1,004,768 | The best rices in Madrid are at these restaurants
The irrefutable fact is that Madrid does not have a beach. What you can count on is the spectacular gastronomy that the capital has to offer; savoring the summer whether you are at the beach or not. For this reason and because we don't have a pool to cool down, we have gone out searching for restaurants – air conditioning included- who know how to elaborate the best rice. Take note because this cuisine truly is causing a sensation.
L'Albufera
With a recently renovated image, the restaurant located in the Hotel Meliá Castilla is the perfect ally if you want to be transported to the Mediterranean. For 35 years, this restaurant has offered one of the most acclaimed and difficult to elaborate Valencian gastronomy. To prepare good rice, it goes without saying that it takes good and prime ingredients, patience and time; with this, it has become one of the best restaurants for rice in the capital. Preparing them upon the order being placed, the restaurant offers a wide variety of choices of arroces melosos, paellas o fideuás. Great options include the Bogavante served with large prawns and the Puerros with fresh clams. As for the paellas, L'Albufera – with lobster, cuttlefish, prawns, and shrimp is a popular option. In addition to the specialty of the house, the menu also has other fish and meat options like the Entrecot de vaca ruby gallega that is matured for 30 days and the Rapito a la bilbaina with traditional ajada. There are also recipes made for vegans and vegetarians like the Parrillada with vegetables of the season.
Average price: 40 € (without drinks)
Hours: Monday through Sunday from 13:00 to 16:00 and from 20:00 to 23:30h.
Address: C/ Poeta Joan Maragall, 43.
Sa Brisa https://plateselector.com/sa-brisa/
The Baleares Islands protagonize the gastronomic offerings of this local restaurant is located in the Retiro neighborhood. It has been exactly a year since this restaurant brought typical Mediterranean cuisine to Madrid with local techniques and products such as homemade sobrepasada, Ibiza salt, and the Xeixa bread, among others. Behind the kitchens plates, chef Gonzalo Aragüez provides a menu that showcases the most representative plates of Ibiza, like the Croquetas de Bullit de peix, the Cochinillo (pig) de porc negre ibicenco (a breed of Balearic pig) and the Empanadas rellenas de sofrito payés. If there is one dish that collects the essence of Baleares is, without doubt, the Mantaza(slaughter) rice. This rice is treated as a traditional plate that is prepared the day the pig is killed for all that participated in the party and this is one of the main claims of the Pitiusa island.
Average price: 40 €
Hours: Mondays through Sundays from 12:00 to 24:00h
Address: Av. de Menéndez Pelayo, 15, 28009 Madrid

Antigua Casa de la Paella
With an eagerness to transform the center of the capital's cuisine back to the tradition of the Casa Lucio, the entrepreneur Luca Gambato opened the doors of this restaurant where the paella and traditional cuisine is converted into the identity of the area. For its gastronomic offering, devised by chef Pablo Velilla, and experience in restaurants like La Bomba Bistrot (where he specialized in rice) and La Vanduca, specialized plates include the sirloin tartar over roasted marrow and carpaccio, the Croquetas of goat milk with jam and of course, the rice. Prepared in a traditional manner with Valencian rice. Here, the restaurant gives the customer the option of choosing between rice dishes that are dry, scorched and crunchy, and soft and gooey. Some of their best options are Duck rice with boletus and vegetables. For the fine diners, there's nothing like succumbing to the lobster. True triumph!
Average Price: 35-40 €
Hours: From 12:00 to 16:30 h. and 19:30 to 00:00 h. Closed Tuesdays and Sundays at night.
Address: C/ de la Pasa, 2
El Caldero https://plateselector.com/el-caldero/
In the center of Las Letras neighborhood, you will find one of the best restaurants in the capital for rice. The owners arrived in Madrid more than 40 years ago with the intention of offering the most representative flavors and dishes of their land. Not only have they done it but they have launched themselves into the Madrid public with their caracoles (snails), paparajotes and their well-known specialty plate archiconocido arroz al caldero. This restaurant has more than ten variations – arroz de chato, de marisco (shellfish), arroz negro, with vegetables, a banda- this is, without a doubt, a favorite. Why? Because of its simplicity, originality and strong flavor. It is elaborated with garlic, tomatoes, ñoras and Mediterranean seafood like mújol. The most interesting part is that it was cooked on the beach and served in a large cauldron.
Hours: Sunday to Monday from 13:00 to 16:00 h; Tuesdays through Saturdays from 13:00 to 16:00 h and from 20:00 to 00:00 h.
Address: C/ Huertas, 15.

1,004,769 | It has an interface described in a machine-processable format (specifically WSDL).
Other systems interact with the web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web standards.
Web services operate over any network (the Internet or a private Intranet) to achieve specific tasks.
The tasks performed by a web service are methods or functions that other applications can invoke and use.
Web service requests/responses can be sent/received between different applications on different computers belonging to different businesses.
Web services also include other technologies that can be used to provide additional features such as security, transaction processing and others.
Much of the promise of web services is its potential for seamless interoperability across heterogeneous systems, platforms, applications, and programming languages. Interoperability is a primary goal of web services. However, it is not a given. Web services standards facilitate interoperability, but do not ensure it. Many considerations and issues need to be resolved to achieve full interoperability. As the number of specifications expands to address gaps, so do the interoperability challenges.
A web service has many potential clients, and this array of clients can use a variety of libraries and providers to connect. Services can, in turn, become clients of otherservices. Ensuring that clients based on different implementations of the standards can interoperate with the service is critical to the service's success.
The primary goal of this article is to demonstrate how to create Java webservice and invoke it from ASP.net (C#) application.
Here we shall develop simple mathematical functions like addition, subtraction etc. using Java web services called JSimpCalcWebService. Later we shall demonstrate how to invoke these web service methods through ASP.net with C# called JSimpCalcWebServiceWebSite.To create there two separate applications we need to use two IDEs. Here in this example we use NetBeans 6 for Java webservice and Visual Studio 2008 for the ASP.net web service client which invokes the web service.
Add web service to the project.
Add operations to the web service.
Deploy and test the web service.
Start the Netbeans IDE; go to the New Project which is available under File menu. The New Project wizard opens.
Select the web from categories options and web application from project section and then press the next button.
On the next screen mention the project name, select the project location. We can also mention the server name in which we want to deploy our webapplication as well we can change the default context path.
Here we mention the project name JSimpCalcWebService and keep the context path same as project name. We use GlassFish V2 application server for deployment.
Now, click the finish button.
Right click on the project name in the Projects explorer window.
From the context menu options select the Web Service menu. A web servicedialog opens.
Mention the web service name and the package name as mentioned in the image below, and then click the finish button.
In our example the web service name is JSimpCalcWebService and the package name is calc.ws.
After we add web service to our application, now it's time to add web serviceoperation or WebMethod. We can do it in two possible ways one is through design mode and anather is through source mode. In our example we use design mode for creating skeleton of WebMethod in easiest way.
As we can see from highlighted section in the figure five we can add webservice operations by clicking Add Operation button. It opens a Add Operation dialog box. Please refer to figure six.
In the Add Operation dialog we must mention name (which is actually aWebMethod name).
We can also enter parameter names and their types (these parameter are known as WebParam).
In the figure six we mention the WebMethod name as addition whose return type is java.lang.String and it takes two parameters (parameter1. andparameter2) of type double. Similarly we create other operations as well like subtraction, multiplication, division, power, maximum,minimum.
Once we finish step three, a basic structure of our web service should be ready. Then we switch from design mode to source mode as shown in figure seven to do rest of the implementation.

1,004,771 | Fun Facts About Jay Z and Beyonce's Vegan Challenge!
Home Celebrities Fun Facts About Jay Z and Beyonce's Vegan Challenge!
Sometimes people who are vegan can be quite annoying. They are always shaming people who don't think and do things their way. But, their idea is good and everybody respects them for what they are doing. It's just that some of them can't understand that this vegan thing is not everybody's cup of tea.
Popular rapper Jay Z and his wife Beyonce have tried going vegan for 22 days. It was their 22-day vegan challenge. Here are some interesting facts about.
They didn't just give up the meats and all the other foods, but they actually stopped wearing everything that they couldn't eat. Beyonce gave up fur and leather, they didn't even wear something like a cow-print sweater.
Before ever committing to this challenge, Jay-Z tried going vegan just for breakfast.
His personal trainer Marco Borges asked him whether or not he could go vegan for his first meal of the day, and Jay Z said that he could do it with ease. He actually loved it so much that he and Queen B decided to do this challenge.
Jay Z was the one who suggested this challenge. Borges wanted him to go on a plant-based diet just for one meal of the day, but he turned it into this 22-day challenge. His wife supported that idea and that's how this challenge started.
This is a nice change that everybody can try out. You may like it but revert to your old habits after the 22 days are over. You may even like it so much that you keep being vegan.
There is also that option where you don't like it and you never want to try it again. That's also okay, at least you tried something different. When somebody talks about being vegan, you can have a nice conversation about it while also knowing what you are talking about.

MAIN STAGE bands:
Canned Heat will be performing on stage Saturday night at the 39th Annual Boogie Canned Heat The legendary band, who performed on Saturday at the original Woodstock festival in 1969, will be performing on Saturday night at the 39th Annual Boogie. They are most known for their hits "On The Road Again" in 1968, "Let's Work Together" in 1970 and "Going Up The Country" in 1969, which all became rock anthems throughout the world, with the later being adopted as the unofficial theme song for the film Woodstock and the "Woodstock Generation." (On stage Saturday night at the 39th Annual Boogie)
WoodstockStory.com — "They hit the Woodstock stage at about 7:30pm on Saturday, August 16th and kept the crowd dancing the entire time under a dark Bethel sky. The setlist featured their greatest hits including "Going up the Country", "Let's Work Together", and "On the Road Again". In the Woodstock film during the song "A Change is Gonna Come" there is footage of a fan climbing the stage and instead of kicking him off, Canned Heat singer Bob Hite shares a cigarette with him."

Big Brother and the Holding Company will be performing on stage Friday night at the 39th Annual Boogie Big Brother and the Holding Company Big Brother & The Holding Company – along with bands like The Grateful Dead, Jefferson Airplane, Quicksilver Messenger Service – is considered one of the original, first wave of great psychedelic bands that came out of San Francisco in the summer of 1965 with legendary singer Janis Joplin. Their songs from the album "Cheap Thrills" and their first Mainstream album are now a part of Rock Music history. Their legacy as one of the great bands of the 1960s is secure. In their shows they perform all of their legendary songs; "Piece of My Heart", "Summertime", "Ball and Chain", "Bye Bye Baby" as only the original creators of this music can. And to show that Big Brother is still a living, creative band they throw in a taste of new, original material that embodies the same signature, Big Brother ideas, and energy.

Randy Hansen will be performing on stage Saturday night at the 39th Annual Boogie Randy Hansen's Jimi Hendrix Experience Forty years after his death, Jimi Hendrix is still leaving an impact on the music world. The recent release of Valleys of Neptune — a collection of previously unreleased studio recordings — rocketed Jimi to #4 on the Billboard 200 Chart, making it the highest-charting album of his career. While the legend of this true "guitar hero" lives on, no one celebrates it more than the remarkable Randy Hansen.
For over thirty years, Hansen has been building a reputation as the foremost Hendrix tribute on Earth. As one of the few players officially recognized by the Hendrix family, he has been successfully doing his act since the '70s, stunning audiences worldwide as he channels the spirit of Jimi and perfectly recreates the stage presence and skill of the legendary axeman. Aside from his loyal fanbase, Hansen's guitar work is respected throughout the music business. He's played alongside some of the greats, including Stevie Ray Vaughan, Steve Miller, Paul Rodgers, Herbie Hancock, and original Jimi Hendrix Experience members Noel Redding and Mitch Mitchell… Also original Band Of Gypsies members, Buddy Miles and Billy Cox. (On stage Saturday night at the 39th Annual Boogie)
WoodstockStory.com "Experiencing Jimi Hendrix live at Woodstock in 1969 may have been the most surreal moment anyone could possibly feel after 3 spacey days of living life. I've heard some describe it as a strong sense of deja vu. Anyone who has ever experienced The Jimi Hendrix Experience should right now take a moment to remember the grooves coming out these cat's earthly instruments…for real."
The Who Generation will be performing on stage Friday night at the 39th Annual Boogie The Who Generation A tribute to The Who, including much of the stage presence and antics of the wild yet talented and influential band. Though we may not completely destroy our instruments on stage, the Who Generation WILL give you the illusion of seeing and hearing one of the greatest rock bands, performing some of the greatest songs ever written! If you're ready for an exciting and dynamic rock show, get ready for the Who Generation! (On stage Friday night at the 39th Annual Boogie)
WoodstockStory.com — "At 5am on Sunday just before the Jefferson Airplane took the Woodstock stage, the rock outfit The Who played their rock opera titled "Tommy". The story of a deaf, dumb, and blind boy who is cured of his ailments and gains stardom became a legendary performance. Although not an apex performance in the Who's career, Woodstock helped solidify the band's place in rock history."

1,004,773 | Osage Tribe - Arrow Head LP. This very professional group formed in Italy in 1971 as a trio consisting of bass, guitar and drums. After releasing two singles in 1971 and 1972 the trio recorded the LP Arrow Head in 1972, which displays their great talent, in particular the one of bass player Bob Callero. The style is hard-progressive-rock of the very fine kind and its album can be considered as one of the foundation albums of Italian rock music today, and as one of the best, too. The lyrics are rather interesting and very well integrated in their music´s style and sound. This official reissue comes with a wonderful FOC and 180-gram vinyl. | RedPajamaC4 | test |
1,004,774 | Is the IT industry asleep at the wheel?
Some of the best money saving inventions are the least complicated. In a world gone virtualisation mad, we could use a reseller who makes life simpler, says Nick Booth
There's a brilliant new mobile app that helps you save money on petrol by being a better driver. You put your smartphone on the dashboard of your car and it monitors how you drive by measuring the lurch factor in your driving.
There's nothing more wasteful than a driving style characterised by aggressive revving and heavy braking, so if you think ahead and take your foot off the accelerator when you see that the lights are red in 200 yards time, you will burn less fuel and get more miles per gallon. Or should that be metres for your litre?
The app, by measuring your heavy footed-ness, makes you think what you're doing and try to drive more efficiently. It has another amazing effect, in that driving becomes less angst ridden and more enjoyable.
Surely that's the key to winning friends in the current economic crisis. Make life simpler and make your customer feel clever. The hallmark of a genius is someone who explains complex stuff so simply that they make you feel clever. If you learn to understand, say, software defined networking (SDN) or virtualisation you can start to feel like a genius. But usually that's only possible because the person who explains it to you is rather clever themselves.
Sadly, few people in the IT industry seem to share this view. There are too many people who want to compensate for their own insecurities by making you feel bad too. Misery loves company, as the saying goes. Confusion is quite gregarious too – as is insecurity.
You can find them all at an IT trade show. Often you will see all three on a discussion panel, where they exhort the audience to take some sort of action they don't really understand themselves. It's the bland leading the bland.
So it's a joy when you find people who have made a simple discovery and want to share their joy with others.
Into this category I would place Brian Waddell, director of Norman Disney & Young, who discovered how companies can cut their fuel bills and shrink their carbon footprint. They need to stop blowing money on fans, he said.
The fans on a server account for 15% of their power consumption, Waddell discovered, by tinkering with them and measuring the effect of temperature on the server's performance. At the risk of over simplifying a complicated study, his top finding is this: If you don't switch the fans on, the server still works.
Think how much Santander UK, with its 4,000 servers, could save if it could switch all its fans off. But it can't because reconfiguring those fans is a tricky and time consuming business. The controlling code, that determines when a rise in server temperature indicates when the fans should be switched on, is buried in the processor. It's an algorithm, embedded in a chipset, and obscured by an operating system designed to be unhelpful on this issue.
So going into system settings isn't an easy option.
For some reason, the server manufacturers don't seem to want to help with this either. "We contacted all the big five server vendors and ask them them to co-operate, but didn't get a single response. They didn't even give us background information," said Waddell.
So much for the IT industry's green credentials.
If only a developer could create an app that could reconfigure all the fan settings on servers. Surely there's money in that!
At the same briefing, I met a small company that makes a system that makes your UPSs last longer. Instead of ditching £150,000 of kit every five years, they can make it last eight. Simple enough story, I thought. But the man selling it got all nervous about the messaging, and refused to talk about it. As if I was going to hack his phone messages, interview the neighbours and go through his bins. (Google CellWatch if you're interested).
It's no wonder the IT industry wastes so many of our precious fossil fuels. There are some terrible drivers on the information superhighway.

I apologize for this bug report then; I was navigating to /boot/preferences. I was clicking on the little Haiku icon on the desktop and I attempted to adjust preferences from there. When I checked /boot/system/preferences, that showed up just fine.
If I may make a suggestion I think it would be nice if that folder in the root was removed or perhaps renamed if possible. Yes I know the argument will be that I should have read the documentation more carefully... but still, to a new user who might be used to clicking a "My Computer" like icon for example, to open the first preferences folder that they're presented with and have it be totally empty is just confusing.

Exodus 31:1-11 describes craftsmen who were "filled with the spirit of God, with ability and intelligence, with knowledge and all craftsmanship." Called to construct the tabernacle based on God's specific instructions, their tasks included making artistic designs in gold, silver, and bronze; cutting stones for setting (the type of work a jeweler does with precious stones or a stonemason with granite or marble for a great building); and carving wood (such as a sculptor, carpenter or cabinetmaker). The craft of making finely worked garments, priestly robes, and liturgical decorations for inside the tabernacle is also outlined. In the Old Testament and today, the instruction to "worship the Lord in the beauty of holiness" is enhanced by those individuals gifted in creating a beautiful atmosphere of worship.
The local church functioned as the central point of community life in Anglo-Saxon times, a dynamic that continued for centuries. The development of guilds during the later Middle Ages was a crucial stage in the professional development of artists. Within towns and cities various craftsmen – weavers, shoemakers, masons, painters, sculptors, and so forth joined together to form guilds that helped maintain quality control, train apprentices, and market their particular craft.
Some guilds originated from prayer societies, and it was also common for people engaged in the same occupation to gather together for worship and prayer. Guilds often took responsibility for providing other charitable services for their members and for their community. The Guild of the Holy Cross in Stratford-upon-Avon, for instance, ran a school, a hospital, and an almshouse.
A Worship Arts Guild, a Performing Arts Guild, a Visual Arts Guild (which includes painting, drawing, stain glass, photography, etc.), a Ceramics Guild, a Music Guild, a Woodworking Guild, a Domestic Arts Guild (canning, making products such as salves, candle making, cooking and more), a Culinary Guild, and a Flower & Garden Guild. Remember that our Guilds are open to anyone in the Kansas City area, and we encourage you to join us so we can learn from you and hopefully offer you something as well.
Contact us for more information about any of our guilds.
Our Needlework Guild brings together women and men of all ages and skill levels to participate in a range of hand-made textiles projects including needlepoint, crocheting, knitting, and embroidery. We seek to glorify God and to nurture the textile arts through projects such as making prayer shawls, afghans, scarves, and more for various outreach opportunities. The Guild's long-term goals also include creating liturgical linens, clerical vestments, and needlepoint prayer kneelers for our congregation.

Electric vehicles threaten to overtake biofuels
January 5th, 2017, by Jan Rocha
A sharp increase in the predicted global number of EVs prompts Brazil to rev up its promotion of low-carbon biofuels.
SÃO PAULO, 5 January, 2017 – By 2040, the number of electric cars in the world could have reached 150 million, or even, if more ambitious targets for emissions reductions are adopted, 715 million. So says the International Energy Agency.
Not only would this mean a drastic reduction in the demand for oil, it could also mean a drastic reduction in the demand for biofuels such as ethanol.
But the biofuel industry is not giving up without a fight. At the recent UN climate talks in Morocco, a consortium of 20 countries launched Biofuture, a platform designed to encourage the use of low-carbon biofuels, including the second generation of sugarcane cellulose-based biofuel. Brazil, the world's second largest producer of both ethanol and biodiesel (the US is the largest) is leading the initiative.
Biofuels solution
Renato Godinho, head of the Energetic Resources Division at Brazil's Foreign Ministry, played down the idea of a massive changeover to electric cars before 2050, saying: "Biofuels are an immediate solution. The climate cannot wait."
Even if there were to be a massive replacement of existing light vehicles by electric models, biofuels advocates believe that the cargo and aviation sectors will be using biofuels for a long time to come.
Artur Milanez, manager of the biofuels department at the BNDES, Brazil's development bank, says: "Even if electrification seems to make sense today, what will define things is the market."
Another reason for Brazil's enthusiasm for biofuels is that giving them a larger share in the economy will enable Brazil to fulfil its Paris Agreement emissions targets, reducing the use of fossil fuels. Petrol sold at the pump already contains 25% ethanol, produced from sugarcane. There are more than 400 sugarcane refineries in Brazil, expected to produce an estimated 26.3 billion litres this year, according to the Brazilian Sugarcane Industry Association.
Brazil began developing biofuels in the 1970s, when, as an oil importer, it was badly hit by the OPEC oil shock. Cars running on subsidised ethanol took over the internal market, but once the price of oil fell and Brazil began developing its own oilfields, petrol reasserted its dominance. Even so, many of the cars produced in Brazil today are still dual fuel, known as flex.
Brazil is leading the initiative for biofuels,
but it is allowing them to be grown
in areas that should be protected
Ethanol was traditionally produced by fermentation, but years of research in government-sponsored labs has resulted in what is called second-generation ethanol. Enzymes are used to break down the cellulose in the bagasse (the fibrous waste of sugarcane, maize and rice). Productivity has been increased by 50%, producing 10,000 litres per hectare.
This new technology has now left the lab and joined industry, but there are still some problems of scale. Once the technology becomes more widely used, it is claimed that Brazil could produce 45bn litres a year, using the area already planted with sugarcane.
"This is almost the 50bn litres Brazil needs to produce by 2030 if it is to meet its INDC [the intended nationally determined contribution to the emission cuts determined by the Paris Agreement]," says Milanez.
But such expansion can be problematic. Potential consumers, such as Germany, are wary because they are concerned that demand will lead to sugarcane being grown in the Amazon, causing deforestation, or will push out small farmers growing food crops, as has already happened in Africa.
This is a real threat, which could easily be avoided by a change in government policy, offering incentives to use the millions of already deforested and degraded acres that have been used as cattle pasture and then abandoned, and paying farmers for environmental services.
Under the present government, which is dominated by agribusiness interests, anti-environmentalists and climate deniers, it is more likely that deforestation will continue apace.
Vegetation loss
A WWF study forecast the clearing of approximately 10m hectares of the cerrado, the vast tropical savannah region of central Brazil, for agriculture in the next 10 years, unless there is a change in policy. It also projected a loss of 30% in the natural vegetation cover in the states of Maranhão and Piaui in the same period.
The western region of Maranhão contains an area of Amazonian tropical forest, while Piauí is a large state that borders the semi-arid area of the northeast.
Cássio Franco Moreira of WWF blames Brazil's Forest Code, approved in 2012, which has allowed agricultural expansion in cerrado areas, where many of the country's principal rivers, including those that flow through the Amazon, have their source, instead of encouraging sustainable agricultural practices.
Once again, Brazil presents a paradox. It is leading the initiative for biofuels, which could reduce carbon emissions. But it is allowing them to be grown in areas that should be protected. – Climate News Network

Geo-engineering unlikely to ease climate fears
November 1st, 2016, by Alex Kirby
Attempts to limit climate change by using the novel technologies known as geo-engineering are very unlikely to work, leading biologists say.
LONDON, 1 November, 2016 – The global watchdog responsible for protecting the world's wealth of species, the UN's Convention on Biological Diversity (CBD), has looked at the hopes for reining in climate change through geo-engineering. Its bleak conclusion, echoing that reached by many independent scientists, is that the chances are "highly uncertain".
"Novel means", in this context, describes trying to reduce greenhouse gas (GHG) emissions by removing them from the atmosphere, and altering the amount of heat from the Sun that reaches the Earth.
Some scientists and policymakers say geo-engineering, as these strategies are collectively known, is essential if the world is to meet the goals of the Paris Agreement. This is because current attempts to reduce emissions cannot make big enough cuts fast enough to keep global average temperatures from rising more than 2°C above their pre-industrial levels, the Agreement's basic goal.
But the CBD says in a report that geo-engineering, while it could possibly help to prevent the world overheating, might endanger global biodiversity and have other unpredictable effects.
Many independent analysts have raised similar concerns.Attempts to increase the amount of carbon in the oceans, in order to remove GHGs, have so far shown disappointing results. One report doubted that geo-engineering could slow sea-level rise. Another said it could not arrest the melting of Arctic ice. A third study found that geo-engineering would make things little better and might even make global warming worse.
Transboundary impacts
The lead author of the CBD geo-engineering report is a British scientist, Dr Phillip Williamson, of the UK's Natural Environment Research Council. He is an associate fellow in the School of Environmental Sciences at the University of East Anglia, UK.
The CBD originally became involved in climate geo-engineering in 2008, because member governments were concerned that experiments to fertilise the oceans could pose unknown risks to the environment (they were then unregulated when carried out in international waters).
The CBD's concern expanded to include other geo-engineering techniques, especially atmospheric methods which could have uncertain transboundary impacts. Some scientists argue that "geo-engineering" is a hazily-defined term and prefer to speak instead simply of "greenhouse gas removal".
Dr Williamson and his colleagues say assessment of the impacts of geo-engineering on biodiversity "is not straightforward and is subject to many uncertainties".
On greenhouse gas removal they warn that removing a given quantity of a greenhouse gas would not fully compensate for an earlier 'overshoot' of emissions.
New risks
In some cases, they say, the cure may be worse than the disease: "The large-scale deployment of bioenergy with carbon capture and storage (BECCS) seems likely to have significant negative impacts on biodiversity through land use change."
When it comes to attempts to reflect sunlight back out into space or to manage solar radiation, a familiar theme recurs: "There are high levels of uncertainty about the impacts of SRM [solar radiation management] techniques, which could present significant new risks to biodiversity."
Time and again, it seems, a potential advance is liable to be cancelled by an equally likely reverse: if SRM benefits coral reefs by decreasing temperature-induced bleaching (as it may), in certain conditions "it may also increase, indirectly, the impacts of ocean acidification." There could even be a risk in some circumstances of loss to the Earth's protective ozone layer.
Dr Williamson and his colleagues believe that geo-engineering is essential – if it can be made to work – because of the diminishing chances that anything else will.
"I'm sceptical. That's not to say bio-energy with carbon capture and storage is impossible, but it seems extremely unlikely to be feasible"
They write: "It may still be possible that deep and very rapid decarbonisation by all countries might allow climate change to be kept within a 2°C limit by emission reduction alone. However, any such window of opportunity is rapidly closing."
Repeatedly, those two words recur: a suggested technique or development will be "highly uncertain". Most of the report amounts to a very cautious call for more research, coupled with an implicit acceptance that in the end geo-engineering is unlikely to prove capable of contributing much to climate mitigation.
Dr Williamson told the Climate News Network: "I'm sceptical. That's not to say bio-energy with carbon capture and storage is impossible, but it seems extremely unlikely to be feasible (for all sorts of reasons)" at the scale needed.
When the CBD member governments meet in December they are expected to call for more research: a safe option in most circumstances, but far from a ringing endorsement of a technology once seen as very promising. – Climate News Network

Renewables fuel optimism in Nepal
June 24th, 2016, by Santosh Koirala
Cattle dung and kitchen waste used in biogas plants are helping to save 400,000 trees a year and reduce fossil fuel imports in Nepal.
RAMPUR, 24 June, 2016 – More than a million extra small biogas plants in Nepal could stop forest destruction and reduce the country's large import bill for fossil fuels − but much more investment is needed to help the impoverished country reach its goals.
The government's 2016 Renewable Energy Subsidy Policy is seeking to ramp up investments in power sources such as small-scale hydro, solar, wind and biomass,
One of the habits it is trying to break is the use of wood for cooking. Currently, 64% of the population, particularly the rural poor, rely on supplies of firewood to prepare their daily meal, causing the destruction of the country's forests.
The whole programme has a significant way to go, because in 2012/13 renewables accounted for only 1.66% of the country's total energy supply, according to the government's Alternative Energy Promotion Centre (AEPC).
Major waste
The largest established form of renewables in this mountainous country is micro-hydropower, with 36 MW of electricity, but biogas also has great potential.
This is because the availability of dung − the major waste used for biogas production in rural areas − is calculated at 12 million tonnes a year, enough to fuel 1.49 million household biogas plants in Nepal. And the methane produced by each micro-plant is calculated to save 1.25 trees a year.
The use of readily-available materials – cattle dung and kitchen waste in rural areas, and sewage and kitchen waste in towns – could fuel a biogas boom to head off a looming energy crisis caused by the ever-increasing import of fossil fuels.
Lack of investment in larger-scale biogas plants
in urban areas has led to a surge in imports
of liquefied petroleum gas
The AEPC says that Nepal, through the use of the existing 320,000 biogas plants and the avoidance of cutting tree cover, is already reducing its overall greenhouse emissions by more than one million tons a year. This is saving 400,000 trees annually, and reducing natural gas imports from India.
A second study by the Biogas Sector Programme says that the biogas replaces 800,000 litres of kerosene.
Known potential
Unfortunately, despite its known potential, the lack of investment in larger-scale biogas plants in urban areas has led to a surge in imports of liquefied petroleum gas (LPG). This has now reached 21% of households.
Despite 670 tonnes of biodegradable waste being generated every day in 58 municipalities across the country, the total number of large-scale biogas plants is only 350. Lack of regular maintenance has led to some of these breaking down
The recently-announced government incentive to subsidise and provide loans to boost renewable energy should reduce this decline. The declared aim is to resuscitate and expand the renewable energy source that has already proved to be a realistic way of reining in the need for fossil fuels. – Climate News Network

Bionic leaf can fuel energy revolution
June 10th, 2016, by Tim Radford
Renewable energy experts and microbiologists have teamed up to create a super-efficient artificial leaf that uses photosynthesis to produce carbon-neutral liquid fuels.
LONDON, 10 June, 2016 − Scientists in the US claim to have beaten nature at its own game. They have created a "bionic leaf" that exploits sunlight to create biomass − and they say their invention is now 10 times more effective than an oak or maple leaf.
"This is a true artificial photosynthesis system," says Daniel Nocera, a leading researcher in renewable energy who is professor of energy at Harvard. "Before, people were using photosynthesis for water-splitting, but this is a true A-to-Z system, and we've gone well over the efficiency of photosynthesis in nature."
Photosynthesis was perfected by the plant world over more than 3 billion years of evolution. It drives the entire living world and it is the primary source of all fossil fuels.
Ancient sunshine
Climate change became a problem only when humans started to extract ancient sunshine in the form of coal, oil and natural gas, stored in the Carboniferous rocks, and put it back in the atmosphere.
Just as wood fires from felled timber make no difference to the atmosphere's carbon dioxide levels – because the same forest that shelters the fallen tree will absorb it again – so biofuels converted from surplus maize or sugarcane should, in theory, make no difference to global warming.
So the idea of what the Harvard team call "bionic leaf 2.0" is an attractive one. It could deliver liquid fuels in convenient form that would make no difference to the planet's overall carbon budget. In effect, it could bypass the vegetation stage.
"It's an important discovery. It says we can
do better than photosynthesis"
Chemists and engineers the world over are racing to exploit human ingenuity and deliver brilliant solutions, including artificial leaves that can capture carbon dioxide. The challenge is to do so effectively, cheaply and on a massive scale.
Which is why Professor Nocera's lab teamed up with microbiologists led by biochemist and systems biologist Pamela Silver, of Harvard Medical School.
The scientists report in Science journal that they have devised a hybrid system based on cobalt-phosphorus alloy catalyst partnered with bacteria called Ralstonia eutropha, which splits water into oxygen and hydrogen at low voltages.
The microbes consume the free hydrogen and, in the presence of oxygen and carbon dioxide, begin some organic chemistry. So far, the system has made isobutanol and isopentanol, and even a bio-plastic precursor product.
The Harvard scientists say their bionic leaf converts solar energy to biomass with an efficiency of 10%. The fastest-growing plants do the same with an efficiency of 1%.
What works in a laboratory may be tricky to translate into large-scale production, but the researchers are confident they have something that works.
Professor Nocera says: "It's an important discovery. It says we can do better than photosynthesis. But I also want to bring this technology to the developing world as well.
"If you think about it, photosynthesis is amazing. It takes sunlight, water and air – and then look at a tree. That's exactly what we did, but we can do it significantly better, because we turn all that energy into a fuel." – Climate News Network

Useful waste offers win-win benefits
February 2nd, 2016, by Paul Brown
An unsung success story in the switch to renewable energy is the use of waste to produce gas – and a valuable by-product.
LONDON, 2 February, 2016 – The future is increasingly bright for renewable energy, with the US aiming to cut the price of solar photovoltaics by 75% between 2010 and 2020. Denmark plans to obtain 50% of its energy from wind just five years from now.
But one form of renewable energy – and one which attracts few headlines – manages to create two useful products at the same time, and is making a growing contribution to combatting climate change.
The medieval alchemists who sought to turn base metal into gold would have thrilled at chemistry that let them turn waste into both fuel and fertiliser. Their twenty-first century successors have discovered the secret of doing exactly that.
Unwanted food, animal waste, municipal rubbish, crop and forestry residues, sewage and dozens of other left-overs of civilisation can and are now being turned into methane to generate electricity, provide district heating and to fuel road vehicles.
Big contribution
This largely unheralded revolution takes different forms across the world, mostly because governments set their own rules to encourage the technology, and also because local circumstances provide contrasting piles of waste. But in every case the waste can be converted into gas for use as fuel.
Although the technology is only part of the solution to climate change, the European Biogas Association estimates that over time it should be able to replace 30% of current natural gas consumption in Europe.
The technology is roughly the same whatever the size of the plant or its location. Biogas plants use microbes to eat waste in an oxygen-free environment to produce methane, and leave fertiliser or soil conditioner as a useful by-product. The plants vary from small household types, very popular in China and India, to farm plants and larger-scale municipal installations in Europe.
Poor relation
The potential of wind and solar power for replacing coal to produce electricity is familiar; the biogas revolution is hardly recognised. The first report on biogas produced by the International Gas Union went virtually unreported.
Yet its details included, for example: "One bag of food waste composted to biogas is enough to power a gas-driven car for almost two kilometres", and: "A bus with 55 passengers can run for 1,000 km on the food waste produced by its passengers each year."
Biogas is produced naturally in environments with no oxygen: swamps, for example, rice paddies and the stomachs of ruminant animals like cattle. An anaerobic digester's microbes produce the methane by eating the organic content of the waste, leaving a nutrient-rich fertiliser as the residue.
Germany and China are the world leaders in turning farm waste into gas, with 8,000 and 24,000 farm-based plants respectively. More surprising perhaps is the fact that China has built 42 million small biogas plants in a decade to turn village waste into fuel.
Compatible mix
Usually the methane produced in these digesters is fed into generators or small power stations on site and used locally. But if it is further purified the gas can simply be fed into a pipeline and mixed with natural gas.
In Sweden, which aims by 2030 to replace fossil fuels in transport with biogas, the number of gas-driven vehicles has doubled to 50,000 in the last five years. One Swedish advance is to cool the gas to -163°C until it liquefies, reducing its volume by 600 times and making it a perfect fuel for large lorries. Demand for biogas outstrips supply in much of the country, which is now using its ample supplies of forestry waste.
Elsewhere, for example in the UK and South Korea, much biogas comes from old rubbish dumps where the methane they emit is piped to mini-power stations on site. More recently, to cut down on waste, local authorities in the UK have begun collecting thrown-away food so that purpose-built anaerobic digesters can convert it into gas and fertiliser.
Scotland, although part of the UK, has a devolved government which recognises that stronger regulation can drive the biogas revolution. – Climate News Network

Grasses' growing role for American cars
January 17th, 2016, by Tim Radford
Second-generation biofuel made from natural grass species challenges ethanol derived from maize crops as the US seeks to reduce its fossil fuel use.
LONDON, 17 January, 2016 – In tomorrow's world, it won't be just the corn on the great American plains that is as high as an elephant's eye. It will be the elephant grass as well.
To deliver on US promises to reduce fossil fuel use, American motorists in future will drive on miscanthus − as elephant grass is also known – and prairie switchgrass.
Researchers led by Evan DeLucia, professor of biology at the University of Illinois, report in a new journal, Nature Energy, that to exploit biofuels – which recycle carbon already in the atmosphere, and are therefore technically "carbon-neutral" – Americans will have to think again about how they manage the change away from fossil fuels.
Right now, the US Environmental Protection Agency's Renewable Fuel Standards foresee that by 2022 American motorists will start up their cars with 15 billion gallons (57 billion litres) of ethanol from corn. But this could be augmented by 16 billion gallons (60 billion litres) of biofuel derived from perennial grasses.
Energy source
The switch to the prairie's native switchgrass (Panicum virgatum) and Eurasian elephant grass (Miscanthus giganteus) will be necessary because there are problems with corn as a source of energy.
One is that, in an increasingly hungry world, it reduces the overall levels of food available. The second is that corn requires annual planting, fertilising and harvesting. Perennial grasses simply grow, and can be mown once a year.
So by turning over surplus land to swift-growing grasses, and at the same time reducing the levels of carbon dioxide released from cultivation, the US could meet its target of a 7% reduction in its annual transportation emissions by 2022. If farmers went on gradually to switch from corn to the grasses, the reduction could get as high as 12%.
"The moral of this whole story is that we need to find a way
to expand the production of second generation biofuel crops"
Professor DeLucia says: "Greenhouse gas savings from bioenergy have come under varying levels of attack, and this paper goes a long way to showing that, contrary to what some are saying, these savings can be potentially large if cellulosic biofuels from dedicated energy crops meet a large share of the mandate.
"This is a viable path forward to energy security, reducing greenhouse gases and providing a diversified crop portfolio for farmers in the U.S."
The researchers used a climate model to test what would happen if land now being used to grow corn (Zea mays) for ethanol – currently, 40% of the corn harvest is used for biofuel – was switched to the two candidate grasses.
Store more carbon
"Our results were staggering," Professor DeLucia says. "Since both of those plants are perennial, you don't till every year. The grasses also require less fertiliser, which is a source of nitrous oxide, and they store more carbon in the ground than corn."
The switch could turn the US Midwest from a net source of greenhouse gas emissions to a "sink" absorbing them. The study assumed that, rather than the most productive soil, the low-yielding land would be converted to grasses for biofuel.
It also factored in some of the other consequences: if the extra billions of gallons of fuel led to a fall in fuel prices, would Americans drive more, and eliminate the carbon savings? Even if that did happen, such a change has the potential to reduce US emissions overall.
But growers have to be sure that energy policies will be consistent, according to the paper's co-author, Madhu Khanna, professor in the Department of Agricultural and Consumer Economics at the University of Illinois.
"The moral of this whole story is that we need to find a way to expand the production of second generation biofuel crops and maybe even displace corn ethanol," she says. – Climate News Network

Nepali farmers get renewable 'green' fertilizer
October 20th, 2015, by Robert Powell
Concerns about environmental damage caused by costly chemicals and worries about climate change are altering farming methods in the mountains of Nepal.
KATHMANDU, 20 October, 2015 – For centuries, Nepalese farmers have been mixing the dung and urine of their buffaloes, cows and goats with vegetable compost to make solid manure.
But scientists and agricultural development experts have now helped eight "climate-smart" villages in the foothills of the Himalayas to make liquid variants of this traditional organic fertilizer.
Special mixes of dung, urine, water and additives – including leaves from trees in local woods – have been developed over the past two years to help fix nitrogen and other important plant nutrients into the soil. The bio-fertilizers are collectively known as "jholmol".
Such organic methods are not only good for the soil, they also contribute to the natural carbon cycle, ensuring carbon is sequestered in the earth.
Beneficial microbes
Some mixes of jholmol – such as those containing leaves from the neem tree and stinging nettles, and a special package of beneficial microbes, called jeevatu − also serve as pesticides to control insects and fungal infections.
Yam Presad, who farms just under half a hectare of land in Naubise, a poor village on the floor of a steep-sided valley two hours' drive east of Kathmandu, has been using jholmol for the past year.
"Jholmol does not increase the amount of rice and vegetables I grow, but it saves me having to buy chemical fertilizers, and people like the produce better," he says.
"The cabbages are not shiny, like they were when we used chemical fertilizers and pesticides, but they taste a lot better. People like the fact that we only use natural products. They regard it as safe food."
The Centre for Environmental Policy, Research and Development (CEAPRED), a Nepal-based NGO, is helping to establish eight "climate-smart" villages in the centre of the country.
Increasingly erratic rainfall is making it more difficult to eke out a living from agriculture. The annual monsoon rains tend to arrive later than in the past, and when the rain does fall it often buckets down in heavy downpours that are interspersed with long dry periods.
Meanwhile, scientists say temperatures across much of the Himalayan region are increasing at twice the global average.
Along with the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD), CEAPRED is encouraging villagers to experiment with new ways of conserving water and new crop-growing techniques that will still give a good harvest, despite the changes in climate.
In Naubise, as everywhere in the deceptively green mountains of Nepal, water is in short supply for both drinking and irrigation.
It is easy for farmers to make jholmol because virtually every Nepalese smallholding has a couple of cows and one or two buffaloes to provide milk and pull the plough.
The manure is often also used for energy – shovelled into tanks to make bio-gas, which powers a gas ring in the kitchen.This saves on wood fuel and helps to preserve the precious community-owned forests that still cover the steepest hillsides.
Population pressure has gradually reduced the size of farms in Nepal over the past 50 years. The average size of a family holding today is just 0.8 hectares – and much less in many hilly areas.
Cash remittances
Most smallholdings are unable to provide adequate food or cash income for a family, so, increasingly, rural families depend on cash remittances from one or more sons who have gone abroad to find work.
Some estimates put the number of migrant workers driven off the land by poverty at more than three million – about 10% of Nepal's 32 million population.
This year, the farmers of Naubise and hundreds of other mountain villages in central Nepal are even more hard-pressed than usual due to the series of earthquakes in April and May that killed more than 8,500 people and destroyed buildings in many communities.
Small self-help improvements such as jholmol are likely to play a key role in assisting the rural poor of Nepal – and potentially other mountainous countries in Asia – to survive in an increasingly harsh environment and deal with the impacts of climate change. – Climate News Network

Scientists push boundaries to find new energy
October 8th, 2015, by Tim Radford
From algae to alloys, ingenuity in the world's laboratories is fuelling experiments to find new ways of providing viable sources of clean energy.
LONDON, 8 October, 2015 – Wind and solar energy remain the only obvious replacements for fossil fuels, but recent research shows that scientists are clearly thinking outside the box to come up with future alternatives. They have recently been able to report at least theoretical progress with nuclear energy, algae, and a novel alloy. In just a few days, they proved that thermonuclear fusion – once somebody works out how to make it happen – will be economically viable. They have worked out how to cultivate green algae for biofuel in huge quantities at US$50 a barrel, which is about the cost of crude oil. They have even found a way to get electrical energy directly from cyanobacteria, or blue-green algae. And they have exploited an alloy that can deliver a colossal pulse of electric power when you kick it.
None of these technologies has advanced beyond the experimental stage, but all are testament to the ingenuity now being deployed in the world's laboratories and experimental start-ups. Fusion power – not to be confused with nuclear fission – exploits the thermonuclear conversion of hydrogen to helium with little or no noxious discharge and the generous release of energy. This is what powers the sun and fuels the planet's life. It is also the basis of the thermonuclear bomb. For the last 60 years, humans have been trying to make fusion work peacefully on Earth, with only tantalising flickers of success. But if it does work, British scientists report in the journal Fusion Engineering and Design, it will not be too expensive. They analysed the cost of building, running and ultimately decommissioning a fusion power station, and found it comparable to fission or nuclear energy. The challenge of nuclear fusion is to heat stripped-down heavy hydrogen atoms to 100 million °C so that they fuse into helium, while finding a way to tap the released energy, and at the same time keep the reaction going.
"What we can say is that our predictions suggest fusion won't be vastly more expensive than fission"
The International Thermonuclear Experimental Reactor (ITER), now being built in the South of France, might in a decade show that it could happen. Assuming it works, the process should be affordable. There would be no high-level radioactive waste, no problems with finding fuel, and no by-product that could be turned into nuclear weaponry. "Obviously we have had to make assumptions, but what we can say is that our predictions suggest fusion won't be vastly more expensive than fission," said Damian Hampshire, of the Centre for Materials Physics at Durham University, UK. "Calculating the cost of a fusion reactor is complex, given the variations in the cost of the raw materials and exchange rates. However, this work is a big step in the right direction." Biofuel is currently based mostly on the conversion of agricultural crops – sugar cane, or corn – to feedstock for ethanol, which can be converted into gasoline or other fuels. But, in a hungry world, this is not an ideal solution. So researchers have been looking at the microbial plant life in waste water and ponds as a possible answer, with promising experimental results on the small scale. But now an Israeli company called Univerve has pioneered a cultivation system that gets ever more sunlight to speed up photosynthesis and get the algae working ever harder They report in Technology journal that they bubbled air through a suspended, modular triangular structure with transparent walls so the algae get their solar energy from all sides and their oxygen at all times. They promise green reactors up to 100 metres, holding 100 cubic metres of "production medium", or algae. There is a bonus: algae make omega-3 oils, so it could also serve the food industry and deliver cattle feed, as well as feedstock for the biofuel business. In Montreal, Canada, researchers report in the same journal that they can tap into the photosynthesis in the tank full of algae and directly retrieve clean energy in the form of electricity. The process involves tapping into the electron transfer chains in the plant life that turn sunlight into carbon-based tissue. In essence, the tank of cyanobacteria serves as the anode in a biological battery.
Commercially-useful
Having demonstrated the principle, the next step is to work out how to get commercially-useful power from what becomes, quite literally, the power plant. In the US, civilian and military scientists have been looking again at an alloy of iron doped with gallium that has been around for decades, but which has just shown that it can produce electricity. It has been named Galfenol, and is described in the Journal of Applied Physics as magnetoelastic. Squeeze or deform it, and its magnetisation changes. Stick it in a magnetic field, and it changes shape. The scientists found that when boxed in a clamp so that it could not deform, wrapped with copper wire and subjected to a powerful impact, Galfenol generated as much as 80 megawatts of instantaneous power per cubic metre. That is, it converted mechanical energy into electromagnetic discharge. Right now, like the other advances, it remains a discovery awaiting an application. But energy researchers are certainly applying great ingenuity to the search for clean energy sources. – Climate News Network

Elephant grass could offer viable alternative to coal
September 29th, 2015, by Paul Brown
By adapting a tropical grass to grow in the British climate, scientists hope to be able to replace coal in power stations with biofuel. LONDON, 29 September, 2015 − The UK government is spending £1.8 million on a scientific project that aims to breed a new seed-producing variety of tropical grass that could provide a viable source of fuel for power stations. Miscanthus, better known as elephant grass, is already being used in Europe to produce biofuel to replace coal in power stations − but growing enough of it is the main drawback. So scientists at Aberystwyth University in Wales are being given government funding to help develop miscanthus strains that like UK conditions and produce viable seeds, without losing the fast-growing and drying properties that make it ideal for biofuel. The variety currently used is Miscanthus x Giganteus, which grows fast – up to three metres tall − on poor agricultural land in Europe to produce a cash crop for farmers in the spring, when the dried stalks from the previous year are ideal for burning in power stations.
Hybrid variety
However, the "giganteus" is a hybrid variety that does not produce viable seeds. To grow a new plant, farmers currently have to break off and sow a bit of the root, or rhizome, of another elephant grass. Even with machines to plant dozens of chopped-up rhizomes, it is very time-consuming to plant enough elephant grass to feed a power station, or to make bio-fuel for cars. If the grass produced seed, areas could be planted 200 times faster. Currently, the UK demand for biomass for electricity is more than 5 million tonnes a year, of which 75% is imported − which partly defeats the object, since transporting biomass uses fossil fuels. The theory is that all of these imports could be replaced by elephant grass if UK farmers were given the means to plant enough.
"We need to develop our economy to take advantage of green technologies, as opposed to relying on a limited stock of fossil fuels"
In addition, smaller local biomass plants could be built near where the elephant grass grows, thus cutting transport costs. And any surplus could be used to produce liquid fuel to power lorries and cars. According to enthusiasts, if a car engine used a gallon of fuel every 25 miles, one tonne of miscanthus could produce biofuel to drive over 750 miles. Once the grass has been planted, it lives for 20 years and produces 10-20 tonnes of fuel per hectare. It is also said to be beneficial for birds and wildlife that live protected inside the almost impenetrable foliage and in the leaf litter between the rows. In some parts of the world, miscanthus varieties that do produce seeds can be a problem as they can block watercourses and are hard to remove once their roots have become established. However, the scientists at Aberystwyth University's Institute of Biological, Environmental and Rural Sciences are confident that they can produce a plant that reproduces and grows well in European conditions, while avoiding any environmental problems with careful management.
Reduce emissions
Dr John Clifford Brown, leader of the project, believes that the crop will benefit the agricultural industry and reduce the UK's carbon emissions. He revealed that the university has already spent 10 years working on developing miscanthus into a crop that can supply the UK's growing biomass demand, and that the seeds of the new hybrids will be planted at four trial sites across the UK to see which performs best. "Several harvesting approaches will be explored to maximise crop quality and quantity," he said. "The overall goal is to develop new systems for miscanthus-based agriculture that increase profitability, and so enable transition of today's niche crop into a large-scale biomass supply system. "The UK needs to reduce CO2 emissions in order to mitigate climate change, and we also need to develop our economy to take advantage of green technologies, as opposed to relying on a limited stock of fossil fuels." – Climate News Network

Cutting warming to 1.5°C could put food supply at risk
May 21st, 2015, by Alex Kirby
Scientists say meeting the tougher demands of many countries on limiting global temperature rise may be technically feasible, but would risk worsening world hunger. LONDON, 21 May, 2015 – As world leaders try to agree how to prevent global warming from heating the planet by more than 2°C above pre-industrial levels, scientists have tackled an altogether thornier question: can we keep the rise below 1.5°C? The lower target − demanded by more than 100 countries as a safer goal − is attainable, they say. But there will be little room for error, and getting there will mean not only cutting greenhouse gas emissions, but actually removing carbon dioxide from the atmosphere. That is not possible with the technology now available. And even if it could one day be done, it would probably have forbiddingly harmful consequences for world food supplies. However, limiting temperature rise by 2100 to less than 1.5°C is still feasible, say the researchers from the International Institute for Applied Systems Analysis (IIASA) in Austria, the Potsdam Institute for Climate Impact Research (PIK), Germany, and colleagues. They report their findings in the journal Nature Climate Change.
Similar actions
Not surprisingly, the answer includes doing more, and doing it faster. "Actions for returning global warming to below 1.5°C by 2100 are in many ways similar to those for limiting warming to below 2°C," says IIASA climate researcher Joeri Rogelj, one of the lead authors of the report. The authors accept that the economic, political, and technological conditions for achieving even 2°C are "substantial". The negotiations to be held in Paris in December by member states of the UN Framework Convention on Climate Change (UNFCCC) may show what chance there is of meeting them. The new study identifies key ways of reaching the 1.5°C target by 2100. One is a tight limit on future carbon emissions. Gunnar Luderer, PIK senior researcher in sustainable solutions, who co-led the study, says: "In 1.5°C scenarios, the remaining carbon budget for the 21st century is reduced to almost half, compared to 2°C scenarios. "As a consequence, deeper emissions cuts are required from all sectors, and global carbon neutrality would need to be reached 10-20 years earlier than projected for 2°C scenarios." Energy efficiency will also need to improve faster, he says.
"The scenarios we assess keep warming to the lowest levels currently considered technologically feasible"
But the study finds that staying below 1.5°C would require a radical step change: some time this century, carbon emissions would have to become negative at a global scale. That is the scientists' way of saying that significant amounts of CO2 will have to be actively removed from the atmosphere. And there is at present no known way of doing that. In theory, it is possible − for example, through bio-energy use, combined with carbon capture and storage. But that is a technology that so far remains untested on a large scale. It would also increase hunger, as the crops needed to produce enough biofuel would compete for land with food plants. Another idea is to grow more forests, which would sequester carbon in their trees, but this would be open to the same objection − that it would reduce cropland. The higher temperatures in prospect will themselves affect forest growth and health.
Lowest levels
Rogelj told the Climate News Network: "Increased temperatures can make afforestation efforts harder. However, the scenarios we assess here keep warming to the lowest levels currently considered technologically feasible, and this issue will thus have a relatively smaller impact." Whatever happens, the authors expect things to get hotter before they have any chance of cooling down. Rogelj says: "Basically, all our 1.5°C scenarios first exceed the 1.5°C temperature threshold somewhere in mid-century, before declining to 2100 and beyond as more and more carbon dioxide is actively removed from the atmosphere by specialised technologies." Over 100 countries worldwide – more than half the members of the UNFCCC, including the Alliance of Small Island States (AOSIS) and the Least Developed Countries (LDCs) – have declared their support for a 1.5°C target. – Climate News Network

1,004,784 | Salt marshes are the coastal wetlands being inundated and drained by every salt water carried by the tides. You can find them out marshy since the soil might possibly be made up of a deep mud and a peat. Peat is made from a decomposing plant matter which is often more than a few feet thick. Peat appears to be waterlogged, root-filled, and even extremely spongy.
For the reason that salt marshes are often immersed by the tides and hold a large amount of decomposing plant materials, oxygen levels in a peat can be very low—a condition generally known as hypoxia. Hypoxia is actually due to the development of bacteria which emit the sulfurous rotten-egg odor which is often related to marshes and the mud flats.
These areas manifest throughout the world, particularly in mid to high latitudes. Flourishing on protected coasts, they are a typical habitat within estuaries. In the U.S., salt marshes exists on just about every coast. Around 50% the nation's salt marshes are situated along the Gulf Coast.

1,004,787 | TEETH-IN-AN-HOUR™ is a revolutionary concept providing patients with fully functioning teeth on dental implants in a single procedure that takes about an hour. This technology was developed by Nobel Biocare and utilizes collaboration between both the restorative doctor and the oral surgeon. This merging of knowledge and experience achieves not only increased safety, but also a more precise implant placement. In addition, the fabrication of a final prosthesis is completed prior to the surgery. The procedure can often be done using computer-guided implant surgery and without requiring any flap reflection. This benefits the patient in that there is less postoperative discomfort, less swelling, and less bruising. Patients can often resume their normal activities the next day.
The process begins when an i-CAT scan is taken of the patient's jaw bone. This i-CAT scan allows for the generation of a three-dimensional model of the jaw bone that can then be used with virtual reality software to plan the precise implant placement without requiring the presence of the patient. The results are a more accurate implant placement and less chair time for the patient. | RedPajamaC4 | test |

1,004,790 | Your Views for January 10
Friday, January 10, 2020, 12:05 a.m.
Science waits for no man — or tradition. Its ability to improve our lives looks back to Galileo staring up in wonder into the heavens and finding that the stars could be touched for the good of all.
Not a moment passes that does not bear witness to science's benefits in our lives. But in its haste to help the lives of ALL people, science can forget the very human need to belong to a particular place and its people.
Keeping the ancestral spirits alive in that people's memory, which the sacred mountain tops do, spells the difference between a living and a dead tradition. Without these living traditions to sustain our unique identity, we would become "lost in space."
To help reconcile these equally valid views, I would make the following proposals (immodest, because they involve deep compromises on both sides).
1. Acknowledgment that both sides begin in the wonder of the heavens and earth.
2. Paint all observatories in earth tones so that they no longer stand out as monuments to scientific rationality, at the expense of traditional views of the sacred mountains.
3. Require all new visitors to stop at the 8,000-foot level of the summit road to undergo a brief education in the significance of the sacred mountains to the Hawaiian people, and the taboos concerned with its desecration, in a structure under the management and control of the Department of Hawaiian Home Lands. But it must be left completely up to the visitor to decide whether or not they will proceed to the summit.
4. Have neutral moderators at all junctures. A hotline could be set up between decision makers on both sides to address more difficult issues, with the proviso that traffic to the summit is left open.
5. Finally, and perhaps most importantly, the summit road above the 8000-foot level should be closed on significant ritual and holy days to both visitors and observatory personnel (beyond a skeletal crew).

Use tracking devices
Failing-to-return furlough worker inmates seems to be an ongoing revolving-door problem.
Many furlough workers are so close to going home to start life anew. Failing to return ends up with an escape charge for the individual, and the chances of going home soon are gone.
Why can't tracking devices be placed upon these inmates when they leave for their work program? Too many fail to return.
Worse case scenario, while out, an inmate commits a serious crime against someone. The victim sustains serious injuries, even death. The Department of Public Safety would be on the receiving end of a major lawsuit. The recent incident on Oahu involved a gun in the possession of a fail-to-return inmate. Need I say more?
Tracking devices are needed on work furlough inmates; the sooner they are found, the better the chances of the public being safe.

ASU hosts filmmakers for an insider look at movie making
The film buzz at ASU continues, as students now have a unique opportunity to hear firsthand about the making of 2008 indie darling "Juno" from the director, screenwriter, studio officials and other key filmmakers in a face-to-face daylong discussion – all part of the Anatomy of a Feature Film series.
The film's director, Jason Reitman, and screenwriter Diablo Cody, among a host of film professionals, will be on hand Saturday, Jan. 26, to talk with students studying the art and craft of filmmaking at the School of Theatre and Film in ASU's Herberger Institute for Design and the Arts about the business of making movies.
"Juno" is a low-budget independent film that went on to win multiple accolades, including Best Screenplay at the 2008 Academy Awards.
Due to a limited number of seating, the event will be livestreamed online, from 10 a.m. to 6:30 p.m. (MST), and is free to anyone who wants to watch.
"The program is a unique opportunity for students to hear how a film was conceptualized, produced, marketed and distributed – from the people who actually made it happen, complete with the hindsight of a successful release," said Adam Collis, professor of practice at the ASU School of Theatre and Film, who helped create the program.
Interviews with guests lined up for the event will be broadcast to ASU via video conference provided by Cisco Systems. The ASU School of Theatre and Film is expanding the interactive teleconference program to include students at Duke University, the University of California Los Angeles Anderson, the University of Montana, and Quinnipiac University in Connecticut and the San Francisco Film Society.
A limited number of seats will be available to ASU students and the general public but only students enrolled in the daylong class are able to direct questions to the participants. Film producer Judd Payne ("As Cool as I Am," 2013; "Bernie," 2011) will host at the UCLA site.
"This program is just one of the ways in which we are bringing both a first-rate education and an understanding of the realities of film and media production to film students at the ASU School of Theatre and Film,'' said F. Miguel Valenti, founder and director of the film and media production programs, and Lincoln Professor of Ethics and the Arts at the school.
"We are a young program, founded on principles of narrative storytelling and ethical decision-making. We are pleased to bring this special Anatomy of a Feature Film event to our colleagues in film programs across the country and we hope to expand the program in the near future," Valenti said.
The events are set to take place all day at the Marston Exploration Theater in the School of Earth and Space Exploration, Interdisciplinary Science and Technology Building IV (ISTB4); 850 S. McAllister Ave., Tempe, Ariz.
There is a screening of "Juno" at 7:30 p.m., Jan. 24 (come at 7 p.m. for pizza) that is also free and open to the public at the Marston Exploration Theater. The screening is part of the ASU School of Theatre and Film's Hollywood Invades Tempe series.

1,004,793 | At least 470 killed in hurricane-hit south-western area of Haiti
A boy stands on top of the hillside of town of Jeremie, Haiti, which was destroyed by Hurricane Matthew (AP)
October 8 2016 16:16 PM
At least 470 people have died in one district of Haiti's hard-hit south-western region after Hurricane Matthew pummelled the area earlier this week.
https://www.independent.ie/world-news/at-least-470-killed-in-hurricane-hit-south-western-area-of-haiti-35114389.html
https://www.independent.ie/world-news/a75b3/35114388.ece/AUTOCROP/h342/PANews_P-5c86d2d7-8d6e-4a1f-ae13-906916d070bb_I1.jpg
Civil protection chief Fridnel Kedler said he expects that number to rise because authorities have not been able to reach two communities in the Grand-Anse area on the peninsula's northern tip.
The overall death toll remains unknown.
Officials are especially concerned about Grand-Anse. When the Category 4 Hurricane Flora hit Haiti in 1963, it killed as many as 8,000 people.
Amid the suffering, aid has begun pouring into the coastal town of Jeremie, where thousands of homes were damaged or destroyed and many people were running low on food and facing an increased risk for cholera.
Dozens of young Haitians came to the small airstrip along the coast to watch as a helicopter was unloaded with crates of food and water.
"My home is totally wrecked and I heard they were bringing food," said Richard David, 22, one of those who came to the airport. "I haven't had anything but water today and I'm hungry."
Saint-Victor Jeune, an official with the civil protection agency working in Beaumont, in the mountains on Jeremie's outskirts, said 82 bodies found by his team had not been recorded by authorities in the capital because of spotty communications.
Most appeared to have died from falling debris from the winds that tore through the area at 145mph on Tuesday.
"We don't have any contact with Port-au-Prince yet and there are places we still haven't reached," Mr Jeune said, as he and a team of agents in orange vests combed the area.
The storm left signs of devastation all around the south-western peninsula. Outside Jeremie, home after home was in ruins. Drew Garrison, a Haiti-based missionary who flew in on Friday, said several fishing villages were submerged and he could see bodies floating in the water.
"Anything that wasn't concrete was flattened," said Mr Garrison, whose organisation, Mission of Hope Haiti, based in Austin, Texas, was bringing in a barge loaded with emergency supplies on Saturday.
"There were several little fishing villages that just looked desolate, no life."
The Pan American Health Organisation and others warned of a surge in cholera cases because of the widespread flooding caused by Matthew.
Haiti's cholera outbreak has killed roughly 10,000 people and sickened more than 800,000 since 2010, when it was introduced into the country's biggest river from a UN base where Nepalese peacekeepers were deployed.
Sophia Cheresal, deputy medical coordinator of Doctors Without Borders in Haiti, said there were at least 18 cases of cholera at the Jeremie hospital.
"It's getting worse and probably some people are going to die."
UN emergency relief coordinator Stephen O'Brien called the hurricane's damage a major blow to Haiti's reconstruction effort and the fight against cholera.
"We expect that homes, schools and cholera treatment facilities have been destroyed and that water systems, roads and bridges have been severely damaged," he said.
He also announced that the UN's Central Emergency Response Fund was releasing five million dollars (£4 million) to help Haiti. Earlier this week, the fund released a loan of eight million dollars (£6.4 million) to Unicef to scale up the response to the cholera epidemic.
Those killed in Haiti by Matthew included a woman and her six-year-old daughter who abandoned their flimsy home and headed to a nearby church to seek shelter, said Ernst Ais, mayor of the town of Cavaillon.
"On the way to the church, the wind took them," Mr Ais said.

This chapter provides a general overview of mitochondrial disorders presenting in the pediatric age group. Although there are a variety of disorders in which mitochondrial dysfunction is a secondary phenomenon (eg, Rett syndrome, Friedreich ataxia), we focus predominately on the disorders that result from germline (although acquired mutations can cause disease as well) mutations to mitochondrial DNA (mtDNA), those that alter mtDNA content and quality (depletion and deletions, respectively), and those that (directly or indirectly) alter the composition and assembly of the oxidative phosphorylation (OXPHOS) complexes. Although the pyruvate dehydrogenase (PDH) complex disorders and the citric acid cycle disorders are often considered within the mitochondrial disease framework, these are covered separately in Chapter 8. Given the complexities of the OXPHOS system, the uniqueness of the mitochondrial genome and mitochondrial transcription, a background on the normal physiology and general principles of mtDNA replication and general mitochondrial biology is essential to understand the phenotypic and biochemical consequences of mitochondrial dysfunction and to rationally plan diagnostic and therapeutic strategies. Although the focus is on pediatric mitochondrial disorders, there is a wide clinical spectrum and a number of the disorders discussed in this chapter can also present in adulthood, particularly the disorders caused by mtDNA point mutations and mtDNA maintenance that result in mtDNA depletion or replication infidelity. | RedPajamaC4 | test |

1,004,800 | Revitol eye cream is an effective and safe emollient made to work on the thin and sensitive skin of the eyes. The natural ingredients of Revitol Eye cream calm puffy skin, retain moisture, reduce dark circles and transport vital vitamins into the skin. The cream helps in achieving the desired results by enhancing collagen production.
What should a user expect from Revitol eye cream?
Revitol eye cream works on both under-eye circles and puffiness while also improving the appearance of the fine lines and wrinkles. According to the manufacturers, one starts getting visible results within a few weeks of use.
How to use Revitol Eye Cream?
In a review by revitol eye cream user, she shared the best method to use it. Use this cream regularly and apply it twice – once in the morning and once before going to the bed.
Some of the active ingredients present in Revitol eye cream are given below. Also, read the role played by them to regain beautiful eyes.
Chrysin – an anti-inflammatory flavonoid, it reduces darkness and puffiness.
Niacinamide – A vitamin- B complex, it locks in the moisture. It is full of antioxidants and anti-inflammatory.
N-Hydroxysuccinimide – it reduces pigmentation.
Fraxinus excelsior bark extract – two ingredients – fraxin and esculin help strengthen blood capillaries thus helping in minimizing the dark circles.
Capric Triglyceride – This coconut or olive oil derivative preserves antioxidants, works as a moisturizer and transfers vitamins into the skin.
All in all, Revitol eye cream has been appreciated by the users. The results are real and cause no discomfort.
I am so excited to share my story with you. The good thing is that now my eye bags have gone, the crow's feet too have smoothened out. My lifestyle left me with very little time to sleep. This gradually started developing dark circles and eye bags which looked horrible and made me look older than my age. I tried making some changes to my lifestyle by increasing my sleeping hours and trying home remedies. But it was all in vain.
This is when a friend of mine introduced me to Revitol eye cream. This cream did wonderfully for her – easing the fine lines below her eyes and reducing those eye bags. This was evident, even I noticed those under eye bags weren't visible when I met her. Her positivity instilled in me a lot of faith and optimism. Without wasting any time, I bought this cream.
A few days of using it and the results started showing up. Slowly the bags seemed settling down. The dark circles looked better. The skin had started lightening up. My confidence started coming back. Now, I have no need to put any make-up to hide anything because my eyes shine naturally. | RedPajamaC4 | test |

1,004,804 | Free Legal Weed: Can You Still Get Freebies at Your Local Dispensary?
What's better than legal weed? Free legal weed. Previously, with patient appreciation days, free product samples and a joint with purchase, there seemed to be so many different ways to get a bigger bang for your buck. These days, legal free weed is harder to come by as California laws put the kibosh on free cannabis goods to anyone except those medical patients with state ID cards.
Under California law, retailers are no longer allowed to give out free cannabis or cannabis goods to their store visitors. The law even puts an end to retailers allowing others (not shop personnel) to give out free cannabis goods at their shop. That means shops, vendors and product brands can no longer shower dispensary comers with samples and goodies – leaving patient appreciation days a little less appreciative. But not so fast, a further reading into the law provides for a little bit of leeway on the subject.
Amongst the many benefits (like lower taxes) that Medical Patients still enjoy, gifted weed is one of them. The law carves out an exception for medicinal cannabis patients or primary caregivers, by allowing retailers to provide them free medical cannabis goods. However, this is conditioned on a slue of criteria that must be met.
One of the most important requirements is that the patient or caregiver be in possession of a valid identification card issued by the Department of Health and Safety. As opposed to a doctor's recommendation (a certificate from a doctor recommending the use of medical marijuana), a state-issued card is an identification card granted by the state allowing medical cannabis patients with qualifying medical illnesses to possess, grow, and transport marijuana within the state. While both a doctors' recommendation and a state issued ID are equally valid and allow for access to medical cannabis, a state-issued card may offer more legal protection to patients and in this case, the ability to receive free cannabis.
In addition to the requirement of a state issued ID, cannabis businesses have to comply with certain requirements in order to be able to give out free cannabis. Specifically, all cannabis freebies must always be entered into the track and trace system and be properly lab-tested or have a warning label stating that good wasn't tested. The track and trace requirement does not take effect until July 1, 2018 due to the transition period that the state has created to allow businesses some time to comply. The same goes for the required testing – all cannabis goods with warning labels are only compliant until the end of the transition period, July 1, 2018, thereafter all cannabis goods must be lab tested without exception.
Even if a patient or caregiver meets the above requirements to receive a gift of weed, the state has put limits on these freebies. The catch - Any gift of cannabis received by a patient has to be applied toward the daily limit purchased by a medicinal cannabis customer. Under California law, retailers cannot sell more than 8 ounces in a single day to one patient unless they have a written recommendation that contains a different amount. Thus, any cannabis goods given to patients will be calculated as part of the 8 ounces patients are allowed to procure at once.
Despite the restrictions on gifting free weed, California has carved out an exception for local jurisdictions that may want to allow for some freebies. California law states that a licensee can donate cannabis, cannabis goods and the use of equipment in connection with any local program or ordinance that allows for gifting of cannabis in the name of compassionate use, equality, or other similar programs. If you are a business owner, make sure to check with your local laws before gifting cannabis.
Organize in your local community to make sure compassionate care is available for those in need! | RedPajamaC4 | test |
1,004,805 | \section{Introduction} \label{sec:introduction}
We have developed the \texttt{MACER} (Massive AGN Controlled Ellipticals Resolved) code
over some time as an instrument for exploring the evolution of massive elliptical galaxies
at high spatial resolution including a relatively complete set of physical processes.
A recent paper \citep{gan_macer_2018} outlines the details of how rotation,
massive dark matter halos, infall of cosmological gas and other features were
recently added and tested. With this additional physical infrastructure
we discovered features expected in the normal evolution of elliptical galaxies
that surprised us but for which there is ample observational evidence:
specifically the formation of circumnuclear cold gaseous discs that are Toomre unstable
and which form massive stars in episodic bursts that fuel the central black hole and
explain the enigmatic ``E+A'' phenomenon. The code, with resolution of parsecs
in the central region, resolves the {fiducial} Bondi radius and hence can treat black hole accretion
and AGN (Active Galactic Nucleus) feedback
in some detail including both radiative (UV \& X-ray) and
BAL (Broad Absorption Line) winds in a fashion that imitates the observed output of black holes
in both their low and high output states.
In this {introductory} paper we describe how we can add 12 chemical species produced
by standard stellar physics and injected into the interstellar medium (ISM) by
asymptotic branch stars (AGBs), type I and type II supernovae (SNe I, SNe II).
This will enable us to address a whole new range of questions. For example,
``What is the chemical composition expected of the BAL winds?'' or
``What iron abundance should be seen in the hot X-ray emitting gas?''.
These are questions that most cosmologically based galaxy evolution codes would have
difficulty addressing because they typically do not have the spatial resolution
{needed to resolve} the central regions where the winds are generated
and a significant part of the new metals are produced.
Half of the observed elliptical galaxies are known \textcolor{black}{to contain}
cold gaseous discs in their centers
(a.k.a circumnuclear disks, e.g.,
\citealt{sarzi_sauron_2006, davis_atlas3d_2011, boizelle_alma_2017}).
As we demonstrated in \citet{gan_macer_2018},
the formation of circumnuclear disk is inevitable
due to the angular momentum barrier, as rotation is the general case.
Since the length scale of an AGN is very small when compared to the galactic scale,
most of the infalling gas (due to radiative cooling)
will {settle in a flat, rotationally supported disk-like structure}
before it reaches the galaxy center (see also \citealt{eisenreich_active_2017}).
Moreover, the gas will cool down further in the circumnuclear disk,
which makes it ideal for star formation.
As cold gas condenses and accumulates on the circumnuclear disk,
such a cold gaseous disk would become highly over-dense, and we found that
some of the over-dense disk rings would be gravitationally unstable
(a.k.a. the Toomre Instability; \citealt{toomre_gravitational_1964, tan_star-forming_2005}).
Consequently, angular momentum transfer and star formation are allowed
at the same time due to the Toomre instability
\citep[e.g.,][]{gammie_nonlinear_2001,goodman_self-gravity_2003,
rice_investigating_2005,thompson_radiation_2005, machida_formation_2010}.
Therefore, one may expect a near coincidence of star formation and AGN activity
--- the former is an important metal enriching source
(by SNe II; \citealt{goodman_supermassive_2004}),
and via accretion onto the supermassive black hole from the circumnuclear disk
and then the AGN wind feedback,
some of the metal enriched gas {will} be recycled
in form of BAL winds ---
in this paper, we will also demonstrate the key role of the circumnuclear disks
in the chemical evolution of massive elliptical galaxies, i.e.,
where the metals are condensed, further enriched and recycled.
In the next section
of this paper we will provide the details of
how we implement the chemical abundance inputs to the code.
We outline briefly in \S\ref{sec:model-improvement} the model improvements
we have made to facilitate the introduction of diverse metallicity components.
In \S\ref{sec:results} we will present some results of computations,
including the chemical distribution in the modeled galaxy,
the radiative features of the metal rich gas, composition expected in the BAL winds.
Conclusions are reserved for final sections.
\section{Chemical Abundances} \label{sec:model}
In the \texttt{MACER} simulations, we solve the continuity equation of the ISM,
together with the conservation laws of momentum and energy,
including source terms due to the stellar evolution of
AGBs ($\dot{\rho}_{\star} $),
SNe Ia ($\dot{\rho}_{\rm I} $) and
SNe II ($\dot{\rho}_{\rm II}$)
(\citealt{ciotti_cooling_1997, novak_feedback_2011, gan_macer_2018}),
i.e.,
\begin{equation} \label{eq:massconsvr}
\frac{\partial \rho}{\partial t} + \nabla\cdot(\rho{\bf v}) + \nabla\cdot\dot{\bf m}_{\rm Q}
= \dot{\rho}_{\star} + \dot{\rho}_{\rm I} + \dot{\rho}_{\rm II} - \dot{\rho}_{\star}^{+},
\end{equation}
where $\rho$ and ${\bf v}$ are the mass density and fluid velocity, respectively.
$\nabla\cdot\dot{\bf m}_{\rm Q}$ and $\dot{\rho}_{\rm \star}^{+}$ are the mass advection
due to the Toomre instability \citep{toomre_gravitational_1964}
and the mass sink term due to star formation, respectively.
We refer to our code paper (\citealt{gan_macer_2018} and references therein)
for the full description of the physics and equations we solve in the simulations.
In this paper, we intend to track the chemical evolution of the metals
by using 12 tracers
$X_i$ (i=1, 2, ..., 12; {mass of each element per unit volume})
for H, He, C, N, O, Ne, Mg, Si, S, Ca, Fe and Ni, respectively
(see also \citealt{eisenreich_active_2017}, \citealt{choi_physics_2017}
for large scale simulations using SPH).
We solve 12 additional continuity equations of the tracers, assuming the chemical species
co-move once after they are injected into the ISM, i.e.,
\begin{equation} \label{eq:metal-tracers}
\frac{\partial X_{\rm i}}{\partial t} + \nabla\cdot(X_{\rm i}{\bf v}) + \nabla\cdot\dot{\bf m}_{\rm Q,i}
= \dot{X}_{\rm \star,i} + \dot{X}_{\rm I,i} + \dot{X}_{\rm II,i} - \dot{X}_{\rm \star,i}^{+},
\end{equation}
where
\begin{equation}
\dot{\bf m}_{\rm Q,i} = (X_{\rm i}/\rho) \cdot \dot{\bf m}_{\rm Q}, \quad
\dot{X}_{\rm \star,i}^{+} = (X_{\rm i}/\rho) \cdot \dot{\rho}^{+}_{\star},
\end{equation}
and ${\bf v}$ is obtained by solving the hydrodynamical equations as ususal.
In Equation \ref{eq:metal-tracers}, the passive stellar evolution, i.e., AGBs ($\dot{X}_{\rm \star,i}$),
SNe Ia ($\dot{X}_{\rm I,i}$) and SNe II ($\dot{X}_{\rm II,i}$), serves as metal-enriching sources,
while with different metal compositions (see Table \ref{tab:metal}).
The advection terms $\nabla\cdot(X_{\rm i}{\bf v})$ and $\nabla\cdot\dot{\bf m}_{\rm Q,i}$
\textcolor{black}{describe the transport and the mixing of} ISM with different metal abundances.
Star formation ($\dot{X}_{\rm \star,i}^{+}$) is treated as a sink of local metals,
but not to change the {local} abundance.

We start the simulations with an initial stellar population of an age of 2 Gyr,
its mass distribution is determined by a galaxy dynamics model
(\citealt{gan_macer_2018}).
As cooling flows develop, a circumunuclear disk forms naturally in the galaxy
center, in which the gas is cold and over-dense. Star formation is then inevitable.
Therefore, we have two stellar populations in our modeled galaxy:
(1) the initial stellar population which is 2 Gyr old at the beginning of the simulation,
and in which all massive stars have died,
while its secular evolution (i.e., AGBs and SNe Ia) is considered in our model.
(2) a new stellar population actively forming
in the central cold gas circumnuclear disk during the simulations
and producing SNe II that plays an important role in the metal enrichment.
We calculate time-dependent nucleosynthesis output returned
to the ISM by evolving stars of a simple stellar population (SSP)
with ``CELib'', an open-source software library for chemical evolution
\citep{saitoh_chemical_2017}.
For the initial stellar population,
we assume a SSP that consists of stars of identical age and chemical
composition, and follows the \citet{kroupa_variation_2001} initial
mass function (IMF) with a stellar mass range of $0.1 \-- 120 M_{\odot}$.
The SSP is assumed of metallicity $Z=1.5Z_\odot$
(where $Z_\odot=0.0134$ is the solar metallicity as quoted in Table \ref{tab:metal}).
This abundance matches that expected for an elliptical as massive
as the modeled one, which should be supersolar (e.g., \citealt{thomas_environment_2010}).
The metallicity-dependent stellar lifetime
is taken from \cite{portinari_galactic_1998}. The stellar ``yields'',
the amount of newly synthesized and ejected elements via
stellar evolution, are adopted from \cite{nomoto_nucleosynthesis_2013},
\cite{doherty_super_2014} and \cite{karakas_updated_2010}
for high mass stars (Type II SNe), massive AGB stars with
$M>6 M_{\odot}$, and low mass AGB stars respectively. Our
time-dependent chemical enrichment calculation shows that the
nucleosynthesis output enriches the ISM mainly via two phases,
an early ($t \lesssim 10$ Myr) phase driven by Type II SNe, and
a subsequent late phase ($t \gtrsim 40$ Myr) driven by AGB stars
(cf. Equation \ref{eq:stellar-mass-loss-rate}).
Since our simulation starts at $t_{\rm age}=2$ Gyr, there will be only AGBs,
and its time-dependent abundance is used in our model as shown in Figure \ref{fig:metal},
while the averaged metal abundance of AGB winds
is also summarized in Table \ref{tab:metal} for the readers' reference.
\begin{figure}[htb]

\caption{Cumulative mass loss from the initial stellar population in individual chemical species.
The lines in colors are the mass fractions of the metals ejected during the passive stellar evolution.
The mass losses are in units of $M_{\star,0}$ (i.e.,
the total mass of the initial stellar population at $t_{\rm age}=0$.)}
\label{fig:metal}
\end{figure}
The initial stellar population also contributes metals via Type Ia SNe
(cf. Equation \ref{eq:snia-rate}).
\textcolor{black}{We adopted the ejecta mass and the nucleosynthesis yields of SN Ia from the N100 model of \citet{seitenzahl_three-dimensional_2013}. According to three-dimensional high resolution hydrodynamical simulations of SN Ia explosion model of \citet{seitenzahl_three-dimensional_2013}, each SNIa explosion distributes 1.35 Msolar ejecta in total, and the chemical composition of the ejecta is Fe, Silicon and Oxygen dominated as summarized in Table \ref{tab:metal}.}
The new stellar population contribute metals, unlike the initial stellar population,
mostly in its early phase evolution via massive stars.
For simplicity, we only consider the metals ejected by Type II SNe.
For such new stellar population formed by gravitational instability
in Toomre unstable circumnuclear disks, we adopt
the \citeauthor{kroupa_variation_2001} IMF,
but with the top-heavy index of 1.65 advocated by
\citet{bartko_extremely_2010} and \citet{lu_stellar_2013},
which is based on the observed stellar disks in the
MW and M31. We adopt a stellar mass range of $1 \-- 50 M_{\odot}$
(cf. Equation \ref{eq:star-formation-imf}).
The time-averaged metal abundance of its SN II phase
is summarized in Table \ref{tab:metal}.
As in \citet{gan_macer_2018}, we also consider the cosmic accretion (i.e., CGM infall)
of low-metallicity gas (cf. Table \ref{tab:metal}) through the galaxy outskirts,
which will dilute the metallicity as it falls into the galaxy and mixes with the ISM there.
In addition, we also recycle the metals via the BAL winds which are injected back
to the galaxy by the central AGN.
Those two processes do not appear explicitly in the equations above, but are
implemented via the designed outer and inner boundary conditions, respectively.
In this way, we can track the chemical evolution, i.e., the metal enrichment,
transportation and dilution, throughout massive elliptical galaxies.
After AGN bursts there are significant mass outflows from the galaxy.
To evaluate the metal abundance of the BAL winds, we keep tracking the chemical composition
in our AGN ``sub-grid'' model \citep{ciotti_cooling_1997, gan_macer_2018}.
As the mass source of the AGN fueling is accreted via
the inner boundary, we record all the metals that pass through to the galaxy center,
so that we are able to calculate the averaged metal abundance of the black hole accretion disk
at any given time. The BAL winds are injected (at the inner edge) back to the galaxy
with the instantaneous metal abundance of the black hole accretion disk.
Finally, we assume the initial ISM is of the solar abundance \citep{asplund_chemical_2009}.
We must emphasize that we have not yet corrected for the depletion of metals
onto dust, and thus our characterization of element abundance is the total
(dust plus gas phase) mass in that element per unit volume in units
of the local mass density. Especially in the cold gas component,
the fractional depletion of refractory elements onto dust grains
may be a large correction \citep{hensley_grain_2014}. We reserve it to our future work.
\section{Model Improvements} \label{sec:model-improvement}
Compared to \citet{gan_macer_2018}, the model setups have been modified as follows
(besides adding the metal tracers) to facilitate the metallicity changes,
to improve the model self-consistency, and to better fit the observed galaxy properties:
I. the initial black hole mass is increased by
a factor of 2 (i.e., to $M_{\rm BH}=6.7\times10^8 M_\odot$)
so as to better match the observed $M_{\rm BH}-\sigma$ relation
\citep{kormendy_coevolution_2013,yuan_active_2018},
while the rest of the galaxy model parameters are the same as in \citet{gan_macer_2018},
i.e., total stellar mass at the present time $M_\star=3.35\times10^{11}M_\odot$,
the effective radius $R_e=7$ kpc, the galaxy ellipticity $\eta=0.2$,
and the dimensionless parameters for the total gravity mass ${\cal R}=20$
and for the length scale $\xi=20$ of the modeled galaxy,
which results in a central projected stellar velocity dispersion of $\sim280$ km/s.
II. in order to describe the ordered rotational velocity
of the stellar component we adopted the usual Satoh decomposition
in our previous papers, with a constant rotation parameter $k$
\citep{ciotti_effect_2017,yoon_active_2018,gan_macer_2018}.
Here we add some flexibility to the modeling by considering
a central value ($k_0$) for the k parameter,
and we reduce it in the outer parts of the galaxy as
\begin{equation} \label{eq:rotation-profile}
k = k_0 \cdot e^{-r/R_e},
\end{equation}
where we adopt $k_0=0.25$.
In this way we can have some control over the amount
of angular momentum stored in the external regions of the galaxy.
III. we adopt the stellar (AGB)
mass loss formula in \citet{pellegrini_hot_2012}
and adopt the coefficient $A=3.3$ to match the assumption of the \citeauthor{kroupa_variation_2001} IMF, i.e.,
\begin{equation} \label{eq:stellar-mass-loss-rate}
\dot{M}_\star = 10^{-12} A \cdot \frac{M_\star}{M_{\odot}}
\left(\frac{t_{\rm age}}{12~{\rm Gyr}}\right)^{-1.3}
\ \ M_\odot/{\rm year},
\end{equation}
where $t_{\rm age}$ is the age of the initial stellar population,
and the fitting formula is valid when $t_{\rm age} \geq 2$ Gyr.
As usual, the SN Ia rate is evaluated as
\begin{equation} \label{eq:snia-rate}
R_{\rm SN} = 0.16\times10^{-12} h^2 \frac{L_{\rm B}}{L_{\odot}}
\left(\frac{t_{\rm age}}{12~{\rm Gyr}}\right)^{-1.1} {\rm year}^{-1},
\end{equation}
where $h$ is the Hubble constant in units of $70~{\rm km}~{\rm s}^{-1}{\rm Mpc}^{-1}$,
and the B-band luminosity $L_{\rm B}$ is derived by adopting a mass-to-light ratio
$\Gamma\equiv M_\star/L_{\rm B}=5.8$ in units of the solar value,
as appropriate for an old stellar population with a Kroupa IMF
\citep{pellegrini_hot_2012}.

\textcolor{black}{IV}. the initial mass function of the newly formed stars in the Toomre unstable disks
is assumed to have a top-heavy profile based on both observations and
theoretical expectations
\citep{goodman_supermassive_2004, bartko_extremely_2010,
jiang_star_2011, lu_stellar_2013}, we assume
\begin{equation} \label{eq:star-formation-imf}
\frac{dN}{dM} = \frac{N_0}{M_\odot} \left(\frac{M}{M_\odot}\right)^{-1.65}
\end{equation}
with a mass range of $1 \-- 50 M_{\odot}$.
Such an IMF gives that $\sim60\%$
of the total new star mass is in massive stars ($M>8M_\odot$),
which will turn into SNe II in a timescale of $\sim2\times10^7$ year.
We assume each SN II leaves a neutron star of $1.4M_\odot$ and
ejects $10^{51}$ erg of energy into the ISM (cf. \citealt{ciotti_agn_2012}).
V. we allow for the fact that the atomic heating/cooling function ($S_{\rm line}$)
is approximately proportional to the local metallicity ($Z \equiv 1-(X_1+X_2)/\rho$)
in units of the solar value $Z_\odot = 0.0134$,
i.e., in the net heating rate $H - C = n^2 (S_{\rm comp} + S_{\rm brem} + S_{\rm line})$,
\begin{equation} \label{eq:line-recomb}
S_{\rm line} = 10^{-23}{{a + b\, (\xi/\xi_0)^c}\over 1 + (\xi/\xi_0)^c} {Z \over Z_\odot},
\end{equation}
$S_{\rm comp}$ and $S_{\rm brem}$
are as usual the Compton heating/cooling and the bremsstrahlung loss, respectively
(detailed description of the heating/cooling functions above can be found
in \citealt{ciotti_agn_2012}).
VI. we use the same CGM infall profile as in \citet{gan_macer_2018},
however, since we start the simulation when the galaxy is 2 Gyr old,
we now also start the CGM infall at that time.
The accumulated mass due to the CGM infall before
$t_{\rm age} = 2$ Gyr is now taken as the initial remnant ISM,
which is $\sim 10^{10} M_\odot$.
VII. the AGN feedback wind efficiency $\epsilon_w$ is reduced from 0.005 to 0.004.
Finally, we solve the ISM hydrodynamical equations, together with the metal tracers, using the grid-based
\texttt{Athena++} code \citep[version 1.0.0;][]{stone_athena:_2008} in spherical coordinates.
We assume axi-symmetry but allow rotation (a.k.a. 2.5-dimensional simulation).
The outer boundary is chosen as 250 kilo-parsec to enclose the whole massive elliptical galaxy,
the inner boundary $R_{\rm in}$ is set to be 2.5 parsec to resolve the Bondi radius.
We use a logarithmic grid ($\Delta r_{\rm i+1}/ \Delta r_{\rm i} = 1.1$) to
divide the radial axis into 120 discrete cells. The azimuthal angle $\theta$
is divided into 30 uniform cells and covers an azimuthal range from $0.05\pi$ to $0.95\pi$.
The numerical solver for the gas dynamics is composed
by the combination of the HLLE Riemann Solver, the PLM reconstruction
and the second-order van Leer integrator.
\section{Results}\label{sec:results}
Before we address the simulation details, it is helpful to discuss the
``closed-box problem'',
i.e., what metal composition could be expected if the metal enrichment is only contributed
by the secular evolution of the initial old stellar population, i.e., via AGBs and SNe Ia?
We can see from Figure \ref{fig:metal} that the metal composition of AGB winds
provides only weak evolution after $t_{\rm age}=2$ Gyr (when the simulation starts),
and we use a fixed metal composition for SN Ia ejecta.
Moreover, Equations \ref{eq:stellar-mass-loss-rate} \& \ref{eq:snia-rate} give that
the ratio between the mass return rates of SNe Ia and AGBs evolves weakly
from 0.008 \textcolor{black}{(at $t_{\rm age}=2$ Gyr)}
to 0.012 \textcolor{black}{(at $t_{\rm age}=13.7$ Gyr)}.
Therefore, the secular stellar evolution (AGBs + SNe Ia)
alone will result in a characteristic metallicity in a narrow range of $2.1 Z_\odot < Z < 2.4Z_\odot$
throughout the host galaxy.
In addition, as mentioned in \S\ref{sec:model}, SNe II contribute to the metal enrichment
when there is star formation,
while star formation mainly occurs in the circumnuclear disk,
where most of the infalling gas is circularized because of angular momentum barrier.
Ideally, local metallicity could be up to $12.7 Z_\odot$ if SNe II dominate the metal
enrichment (cf Table \ref{tab:metal}).
We will demonstrate in the rest of this section that the metal enrichment
in the circumnuclear disk is the key to
understanding the chemical evolution of the modeled galaxy.
Therefore, it is worthwhile to analyze the circumnuclear disk in advance
(see \S\ref{sec:CND}).
Following the physical sequence, i.e.,
formation of the circumnuclear disk, star formation, mass inflow, BAL winds, and
then metal transportation, we perform in \S\ref{sec:sf-bha-correlation} detailed analysis
on the star formation and black hole feeding processes.
In \S\ref{sec:metal-budget}, we present the overall gaseous mass and metal budget.
In \S\ref{sec:metal-distribution}, the spatial distribution of metals is presented,
and we will see the role of the BAL winds in transporting metals throughout the modeled galaxy.
Finally, the radiative features of the metal-enriched hot ISM are calculated in \S\ref{sec:radiative-featues}.

The averaged age and metallicity of the new stellar population are 7.52 Gyr
and $Z/Z_\odot=5.82$, respectively.}
\label{fig:star-formation}
\end{figure}
\subsection{Circumnuclear disk} \label{sec:CND}
In Figure \ref{fig:hydro-properties}, we present the hydrodynamical properties
of the ISM during the burst event at $t_{\rm age}=12.1$ Gyr.
The gaseous counterpart of the circumnuclear disk is found
of a size $\sim150$ parsec, and of mass $\sim2.5\times10^8M_\odot$
(see Figure \ref{fig:star-formation} for the stellar counterpart).
It is shown in the polar regions that the high-speed BAL winds
launched by the central AGN
can be heated up to $10^8$ K, which should be capable in emitting X rays.
We have designated as BAL wind gas flowing out
of the galaxy center with radial velocity $\geq 1000$ km/s.
Also, metal-rich gas, recycled from circumnuclear disk, will be transported
through the galaxy by virtue of the high-speed BAL winds.
In Figure \ref{fig:star-formation}, we show the cumulative star formation
in the circumnuclear disk, which is $\sim 6.5\times10^9 M_\odot$ at $t_{\rm age}=12.1$ Gyr.
The stellar disk of the newly formed stars is of a thin geometry,
and its size is $\lesssim150$ parsec, which coincides with the cold gaseous disk
(cf. Figure \ref{fig:hydro-properties}).
Recall that we have two star formation algorithms
in our model setup: one is based on the Toomre instability
and the second on the local Jeans timescale,
with the latter allowed only in the densest gaseous zones
with hydrogen number density $n_H>10^5~{\rm cm}^{-3}$ \citep{gan_macer_2018}.
So, most of the star formation is confined to the innermost region of the circumnuclear disk.
In the simulation, we are able to track the age and the in-situ metallicity
of the newly formed stars, as shown in Figure \ref{fig:star-formation},
the averaged age and metallicity of the new stars are 7.52 Gyr
and $Z/Z_\odot=5.82$, respectively.

as shown with the blue (open) and yellow (filled) cycles.
We find a tight correlation of $\dot{M}_\star^+ \sim 7.7 \dot{M}_{\rm BH}$.

\end{figure}
\subsection{Star formation vs. mass accretion} \label{sec:sf-bha-correlation}
As we discussed previously,
it is the Toomre instability that primarily triggers star formation
and allows mass inflow simultaneously.
So it is unavoidable to expect a coincidence between AGN bursts and star formation
\citep{goodman_self-gravity_2003, Kawakatu_coevolution_2008,
Imanishi_infrared_2011, Diamond-Stanic_relationship_2012, Esquej_nuclear_2014,
yang_black_2017,
Izumi_circumnuclear_2016, Izumi_circumnuclear_2018}.
In Figure \ref{fig:light-curves}, we plot the history of star formation rate $\dot{M}_\star^+$ (blue line)
and the mass inflow rates (that through the inner boundary $\dot{M}_{\rm in}$ in yellow line,
and that onto the black hole horizon $\dot{M}_{\rm BH}$ in green line, respectively).
As expected, the AGN activities are usually coincident roughly with star formation,
and the instantaneous star formation rate $\dot{M}_\star^+$ is typically much larger than
the mass inflow rate through the inner boundary $\dot{M}_{\rm in}$
(or the black hole accretion rate $\dot{M}_{\rm BH}$).
That is, star formation consumes most of the cold gas within the circumnuclear disk
before it can fall onto the central supermassive black hole.
This also means that SNe II in the new stellar population can play a very important
role in enriching metals (see \S\ref{sec:metal-budget} for detailed analysis).
In Figure \ref{fig:bh-sf-correlation}, we present the scatter plot
between the black hole accretion rate $\dot{M}_{\rm BH}$
and star formation rate $\dot{M}_\star^+$,
where we bin the timing data in Figure \ref{fig:light-curves} with adjacent time intervals
of $\Delta t = 10^6$ and $10^7$ year, respectively,
as shown with the blue (open) and yellow (filled) cycles.
We find a tight linear correlation of $\dot{M}_\star^+ \sim 7.7 \dot{M}_{\rm BH}$.
Note that no correlation can be found before binning the data,
due to the time lags between star formation and black hole accretion.
To evaluate the time lags, we perform the calculation below,
\begin{equation} \label{eq:time-lag}
F(\Delta t_{\rm lag}) = \frac{\int \dot{M}_\star^+(t)\cdot \dot{M}_{\rm BH}(t+\Delta t_{\rm lag})\;dt/T}
{\int \dot{M}_\star^+(t)\;dt/T \cdot \int \dot{M}_{\rm BH}(t)\;dt/T}
\end{equation}
where $T=12$ Gyr is the duration of the simulation.
The results are shown in Figure \ref{fig:bh-sf-time-lag}.
It indicates that the time lag between star formation and black hole accretion
is about few $10^6$ year.
\subsection{Overall chemical budget} \label{sec:metal-budget}
The cumulative chemical yields from the initial (old) stellar population
and the new (young) stellar population
are shown in Figure \ref{fig:cumulative-chemical-yields}
with the solid and dashed lines, respectively. During the simulation,
the old stellar population ejects in total $\sim 3.4\times10^{10} M_\odot$
of total mass into the ISM ($\sim 10\%M_\star$; cf Equations
\ref{eq:stellar-mass-loss-rate} \& \ref{eq:snia-rate}).
The cumulative star formation is $\sim 6.7\times10^9M_\odot$ in total,
of which $58\%$ is injected into the ISM via SNe II (cf Equation \ref{eq:star-formation-imf}),
i.e., the new stellar population contributes $\sim1/10$ of the total stellar mass loss
(see the black lines in the top panel),
while it dominates the chemical yields of Neon and
contributes significantly to Oxygen as shown in the middle panel.
The new stellar population also contributes a significant fraction of heavy metals
when compared to that of the initial stellar population as shown in the bottom panel.
Note that star formation mainly occurs in the circumnuclear disk.

$\sim1/10$ of the total mass loss, while it dominates the chemical yields of Neon and

The new stellar population also contributes a significant fraction of heavy metals
when compared to that of the initial stellar population (bottom panel).
}}
\label{fig:cumulative-chemical-yields}
\end{figure}
With the metal sources and the flow pattern as described above, we are ready to analyze the
metal enrichment and its transportation throughout the modeled galaxy.
As shown in Table \ref{tab:metal},
SN II ejecta is enriched in alpha elements (especially Ne and O);
SN Ia ejecta is of the highest mass fraction of Fe and Si;
AGBs produce a relatively high fraction of Nitrogen.
So it is possible for us to track the stellar evolution by using the elements mentioned above.

\subsection{Spatial distribution of metals} \label{sec:metal-distribution}
In Figure \ref{fig:metal-distribution}, we present the spatial distribution of the metallicity Z
and individual chemical species (Fe, Ne, C, O, S) during the burst event at $t_{\rm age}=12.1$ Gyr.
We find that the characteristic metal abundances are different from place to place,
accordingly, the modeled galaxy can be divided into three parts:
(1) the circumnuclear disk, i.e., ($r=0.10$ kpc, $\theta=\pi/2$) and the surrounding region;
(2) the BAL region, i.e., ($r=0.05$ kpc, $\theta\le\pi/6$);
(3) the main body of the galaxy on the length scale of 10 kpc, i.e., ($r=10$ kpc, $\theta=\pi/2$).
We sample the metal abundances from the representative locations above
and show the results in Table \ref{tab:fluid-sample}.
The high metallicities found in the BAL region and in the cold disk
are consistent with the SDSS observations
(e.g., \citealt{nagao_evolution_2006,xu_evolution_2018}).

* The metal abundances are sampled at $t_{\rm age}=12.1$ Gyr from
the hot ISM ($r=10$ kpc, $\theta=\pi/2$),
the cold circumnuclear disk ($r=0.10$ kpc, $\theta=\pi/2$), and
the BAL region ($r=0.05$ kpc, $\theta=\pi/6$), respectively.
All the measurements are in the solar units as defined in Table \ref{tab:metal}.
\end{table}
As shown in top-middle panel of Figure \ref{fig:metal-distribution},
the main body of the galaxy shows the highest Fe abundance
(e.g. at $r\sim10$ kpc, $\theta=\pi/2$).
As we discussed previously, the secular stellar evolution
of the old stellar population dominates the metal enrichment
since there is no star formation in the main body of the galaxy.
The typical value of the metallicity Z is $\sim2.3Z_\odot$,
and it follows the abundance pattern of AGBs + SNe Ia (cf. Table \ref{tab:fluid-sample})
as discussed at the beginning of this section.
As shown in top-left panel of Figure \ref{fig:metal-distribution},
the circumnuclear disk has the highest metallicity,
with a typical value up to $\sim8 Z_\odot$ in the innermost region
and decreasing to $\sim2.3 Z_\odot$ at its outer edge.
Obviously, SNe II play a crucial role in the metal enrichment within the circumnuclear disk.
Note that the disk here seems much more puffy than its geometry seen
in the hydrodynamical counterpart (cf Figure \ref{fig:hydro-properties}),
which is because the massive SN II explosions contaminate the chemical composition
above and below the disk.
We use Neon to track the contributions of SNe II to the metal enrichment
in the upper-right panel, we can see that the spatial distribution of Neon
follows well with the biconical structure of the BAL winds
(cf Figure \ref{fig:hydro-properties};
alpha elements shown in the bottom panels of Figure \ref{fig:metal-distribution}
also share the similar patterns).
As we mentioned, the AGN feeding process is mainly via the circumnuclear disk.
Therefore, the BAL winds would naturally inherit the high metallicity of the circumnuclear disk,
and spread the metal-rich gas in a fashion of biconical winds.
The metallicity of the BAL winds is up to $\sim8 Z_\odot$ and
on average (mass-weighted) it is $\sim3.96 Z_\odot$, because it is diluted by the ISM while the wind is propagating through its host galaxy. Detailed metal composition of the BAL winds (during three representative burst events, at $t_{\rm age}=4.0, 8.1, 12.1$ Gyr, respectively) can be found in Table \ref{tab:BAL-metal},
as previously, we define the BAL winds as the components
moving with radial velocity $\geq1000$ km/s.
We also see at the early epochs that the galaxy outskirts has extremely low metallicity
because of the dilution due to the low-metallicity CGM infall (not shown here).
When such gas cools down and falls onto the galaxy,
it would also dilute the metal abundance in the circumnuclear disk.

\subsection{Metals seen in X-rays} \label{sec:radiative-featues}
As a result of metal enrichment, the radiative
cooling and {\it photoionization} heating of the ISM are significantly enhanced.
We pay special attention to finding observable features which can be used to test our model.
In the rest of this section,
we will perform detailed analysis on the radiative features of the hot ISM,
and illustrate the advantages of computing detailed metallicity.
The post processing is based on the hydrodynamical data.
The frequency-dependent radiation is calculated
using the atomic database \texttt{ATOMDB} (version 3.0.9;
assuming collisional equilibrium),
for example, at any given time and location,
we retrieve the ISM properties, i.e., its density, temperature,
and the detailed abundance of the 12 chemical species.
Then, we take such output from the \texttt{MACER} simulation
as the input of \texttt{ATOMDB},
ultimately, the latter would give us the emissivity in the energy band of interest.

In Figure \ref{fig:xray-spectra}, we plot the representative X-ray spectra
for the hot ISM and BAL winds as sampled in Table \ref{tab:fluid-sample}.
The BAL sample is of a typical temperature $\sim2\times10^7$ K,
and that of the hot ISM is $\sim5\times10^6$ K.
With the metallicity-dependent emissivity,
we are able to synthesize the radiative features of the hot gas.
In the top two panels of Figure \ref{fig:xray-weighted-properties},
we plot the X-ray luminosities and the mass of the hot ISM.
We can see that the ISM X-ray luminosity decreases
systematically from redshift z=3.2 to 0, which is mainly because of
the decrease of gas content in the modeled galaxy.
In the lower panels of Figure \ref{fig:xray-weighted-properties}, we analyze
the X-ray-emission weighted properties of the hot ISM.
We average a quantity of interest $P$ in the manner below,
\begin{equation} \label{eq:xray-weighted}
<P> \equiv \frac{\int{\; j_\nu P \; \mathrm{d} V}}{\int{\; j_\nu \; \mathrm{d} V}}.
\end{equation}
where $j_\nu$ is the X-ray emissivity in the energy band of 0.3-8 keV.
In the volume integrals above, we exclude the disk region
($r<200$ parsec and $\pi/3 < \theta < 2/3\pi$)
and the densest zones with $n_{\rm H}>10^2~{\rm cm}^{-3}$,
i.e., which corresponds approximately to a column density of $10^{23} ~{\rm atom}/{\rm cm}^2$
and may be optically thick to X-rays \citep{ballantyne_obscuring_2008};
The X-ray-emission weighted ISM temperature is presented in the second panel from bottom,
the typical temperature is $\sim 0.7$ keV which is comparable to the virial temperature
on the length scale of 10 kpc.
The averaged metallicity is shown in the bottom panel,
of which the typical value is $\sim2.5Z_\odot$,
while with Fe abundance approximately $\sim6\times$ the solar value.
\section{Conclusions and Discussions} \label{sec:conclusions}
We have developed the \texttt{MACER} code as an instrument for exploring
the evolution of massive elliptical galaxies at high spatial resolution
down to and within the fiducial Bondi radius, which enables us to evaluate the
black hole feeding and feedback processes in a self-consistent way,
and to track the coevolution between the supermassive black holes
and their host galaxies.
In the \texttt{MACER} simulations, we paid special attention to
the internal secular stellar evolution
which plays a crucial role in driving the galaxy evolution
as important sources of mass and energy for the ISM.
As an increment to the \texttt{MACER} code, in this paper,
we track the recycled mass from the stellar physics
with its detailed chemical abundances.
Such an increment provides us unprecedented details of the ISM properties,
which are testable by direct comparison with observations.
To trace the metal enrichment, transportation and dilution processes, we solved 12 additional continuity equations dedicated to H, He, C, N, O, Ne, Mg, Si, S, Ca, Fe and Ni respectively.
The metal yields, from AGBs and supernovae of type Ia and II,
are calculated based on standard stellar physics.
The chemical species are assumed to co-move once after they are injected into the ISM,
and they are naturally mixed following the fluid motion.
As expected, a Toomre unstable circumnuclear disk forms in the galaxy center
with a size of $\sim150$ parsec,
which plays a crucial role in the chemical evolution of its host galaxy
--- it is where the metals are condensed, further enriched and recycled.
The half mass radius of the new stars is roughly 20 parsec.
More specifically, the massive stars formed in the cold gas disk
supplement a significant fraction of metals.
From Figure \ref{fig:star-formation} we see that of order $10^6$ massive stars
will be formed over the lifetime of a massive galaxy.
In their death throes, they will produce core collapse SNe II spewing out
alpha rich chemical products.
As a result, the metallicity of the disk in the innermost region reaches up to $\sim8 Z_\odot$
(Figure \ref{fig:metal-distribution}).
Such metal-rich gas will be captured by the supermassive black hole,
and then much of it will be recycled back to its host galaxy by virtue of high-speed BAL winds.
The latter can be readily observed.
We found that the simulated metallicity in the BAL winds could be up to $\sim 8 Z_\odot$,
while that of its host galaxy is $\sim 2.3 Z_\odot$.
The X-ray emitting hot gas is very metal enriched with a fluctuating value
typically near $3 Z_\odot$.
Our results are well consistent with the clear correlation found observationally
between quasar luminosities and their nuclear gas metallicity
\citep{warner_relation_2003, nagao_evolution_2006,
matsuoka_mass-metallicity_2011, xu_evolution_2018}.
\citet{xu_evolution_2018} analyzed the metallicity of quasar broad line region (BLR)
with a large SDSS sample. They found that the metallicity in the most massive galaxies
is $\sim 2 Z_\odot$, while the BLR metallicity is $0.3 \sim 1.0$ dex larger
than their host galaxies and it does not evolve with cosmic time.
It indicates that the metal enrichment is due to recent star formation
rather than secular stellar evolution, as we found in this paper.
In the \texttt{MACER} simulation, the spatial resolution is close to the BLR length scale,
we also found clear correlation between star formation and AGN bursts
(but lagged in time by roughly $10^6$ years),
and thus significant metal enrichment in the galaxy center.
The ratio of star formation in the circumnuclear disk to
accretion towards to the central supermassive black hole is 2.3,
and of that amount the bulk (62\%) is blown out in the BAL winds
with a fraction of 38\% finally accreted onto the black hole.
Our simulated metallicity, both for the innermost central region
and for the main body of the modeled galaxy, is larger than
derived from X-ray observations
(e.g., see \citealt{humphrey_chandra_2006}, \citealt{mernier_radial_2017} for the abundance of the hot ISM of early-type galaxies). However, there are a number of uncertainties when deriving abundances from the X-ray spectra (see \citealt{kim_metal_2012} for a review). Also,
dust depletion of metals could be a significant factor
(e.g., see \citealt{lakhchaura_possible_2018} for a recent analysis). Additionally we assumed
a metallicity of $1.5Z_\odot$ which seemed reasonable given that
the velocity dispersion of our test galaxy is roughly double that in the MW spheroid.
However, as noted earlier, \cite{conroy_early-type_2014} would give our test galaxy
a Fe abundance (in the old stars) slightly less than the solar value.
One important caveat should be noted in our discussion of the expected
chemical abundances in the X-ray emitting gas. We allowed for CGM infall
of metal poor gas, but the amount of infall in our fiducial simulation was
only $1/12$ of the stellar mass of the initial galaxy, and even somewhat less than
that ($\sim1/20$) when we corrected for starting at $2$ Gyr. This could be too low
an estimate and, in any case, will vary from case to case depending on the
detailed cosmic environment. To check on the sensitivity to this component
we have run a case with three times higher CGM inflow ($1/4$ of the initial
stellar mass corrected to $\sim1/7$ of the stellar mass at $t = 2$ Gyr). In this test run
the CGM inflow dilutes the metallicity enrichment to such an extent that the
final X-ray-emission weighted metallicity
drops to $\sim1.5$ times solar by roughly a factor
of two from our fiducial run. Thus the expected metallicity of the hot Xray
emitting gas has an almost factor of two uncertainty depending on the
cosmic environment --- an uncertainty that can only be addressed by simulations
that are both cosmologically correct and have very high internal spatial
resolution.
\textcolor{black}{We leave it to our future work to explore the consequences of higher
CGM inflow (at 1/7 of the initial stellar mass) as indicated by cosmological simulations.}
The massive stars formed in the Toomre unstable central cold gas disk
should have dramatic observable consequences, besides the metal enrichment.
For example, the SN II going off in the central disk will also produce
a copious X-ray output.
However, those SN remnants occur in such dense regions
that even the X-ray may not be observable
except from the ``runaway'' star explosions and these are not
allowed for in the current simulations.
In addition, the (million) neutron star and black hole condensed remnants of the exploded
early type stars must be considered. If they survive in the discs, then
accretion onto them should have major consequences and they would
be dramatically visible in the ``E + A'' phases when the gas discs have
largely dissipated. But there is another phenomenon which may intervene.
The embedded condensed remnants will interact with the dense gas
disk and be dragged into the central supermassive black hole
in a manor labeled Type I migration first discussed by
\citeauthor{goldreich_disk-satellite_1980}
(\citeyear{goldreich_disk-satellite_1980}; which is important in planet formation).
Using the Equation 70 of \citet{tanaka_three-dimensional_2002},
we estimate that the migration time is comparable to the Hubble time especially for
$10M_\odot$ black holes. Using Type I migration underestimates the migration rate
since it does not allow for the fact that the discs are so dense that in places
they are marginally Toomre unstable. This predictable set of processes
would produce high mass ratio black hole captures
(a.k.a. ``Extreme Mass Ratio Inspiral", or in short EMRI) which,
while undetectable by LIGO,
would be candidates for LISA detection (e.g., \citealt{babak_science_2017}).
A zeroth order estimate of the rate gives $10^{2.5}$ events/year within 1000 mpc.
In this paper, we did not consider the effect of runaway stars
in the star-forming circumnuclear disk, which could be
important in spreading metals in the galaxy center.
We also did not yet consider the dust effects in depleting metals and obscuring radiation,
which could alter the radiative features of the circumnuclear disk significantly.
In the near future, we will introduce the above effects into
the \texttt{MACER} simulations, aiming to interpret/predict
the observed/observable radiative features of the ``E+A'' phenomena.

1,004,806 | After keeping company with a comet for the last two years, a spacecraft is about to get a whole lot closer to it. Engineers will nudge it to a gentle touchdown at the end of the month. That'll provide the sharpest views of any comet to date.
Rosetta entered orbit around Comet 67P Churyumov-Gerasimenko in August of 2014. It dropped a probe a few months later, but the probe landed awkwardly and soon expired.
Even so, Rosetta revealed a great deal about the comet. It found that 67P is shaped like a rubber duck, with two lobes joined by a narrow neck. A recent study found that the two lobes may have split apart and come back together many times over the comet's history.
Rosetta also measured the comet's composition. It detected an amino acid and other compounds that are important for life, suggesting that comets might have delivered some of the ingredients for life to Earth. But it found that the water on 67P doesn't match that found on Earth. That might mean that Earth's water did not come from comets, as scientists have long suggested.
Over the next few weeks, Rosetta will drop closer and closer to the comet, then touch down, snapping pictures and taking other readings along the way. But it's not designed as a lander, so its solar arrays won't be able to gather sunlight, and its radio antenna won't be able to aim at Earth — bringing its mission to an end.
A mission to an asteroid is just about to get started. More about that tomorrow. | RedPajamaC4 | test |

As what to the monument concerns, it was encharged to the french sculptor Louis Carrier Belleuse, disciple of Rodin and even it is argued that the master participated in some of the parts of the monument. It was shipped to Limon port, transported to San Jose and assembled, its inauguration was celebrated in 1895 with the greatest honors to the heroes that parcipated in the campaign. It is made up of seven figures and a pedestal, five of them representing the five central american republics of the time, another is the invader being expelled and the last depicts a dead soldier from the costarrican army.
Finally and I have said in other reviews, it does not have definitively value for a WHS proclamation, but its importance in national terms is obvious and deserves to be kept for the future generations. | RedPajamaC4 | test |

1,004,811 | Nordform to merge with S:t Eriks, creating Sweden's largest independent supplier of pre-fabricated concrete pro¬ducts for infrastructure
By merging their businesses, Nordform and S:t Eriks create Sweden's largest indepen¬dent supplier of pre-fabricated concrete products for infrastructure. After the transaction, Segulah III, L.P. will be the majority shareholder in the new group.
Nordform and S:t Eriks, with a joint 2008 turnover of 900 MSEK (85 MEUR) and 400 employees, act as suppliers to all major construction companies and DIY-chains on the Swedish market. In total the companies have 12 manufacturing facilities spread through¬out Sweden.
Nordform was acquired by Segulah III, L.P. in June 2005. S:t Eriks is a subsidiary of the nationwide construction company Peab.
The merger of the two companies will improve R&D and Sales, and make pro¬duction more efficient. In addition, the aim is to establish presence in the other Nordic markets.
"There are extensive synergies between the companies and we see great potential for both efficiency improvements and Nordic expansion" says Chairman of the Board Lennart Kalén.
The new company will operate under the name S:t Eriks. Head office will be located to Nordform's current head office in Staffanstorp. The Marketing & Sales function will be located to Uppsala.
Nordform's subsidiary Skandinavisk Kommunalteknik AB will not be included in the deal and going forward will hence be owned directly by management and Segulah III, L.P. as a new portfolio company.
Approval from the competition authorities have been received in Sweden, Norway and Finland.

1,004,812 | Jayden Russell: KU football newcomers 'hitting the ground running' this week
Photo by Nick Krug
Kansas signee Jayden Russell scans the practice facility during football practice on Wednesday, March 6, 2019 within the new indoor practice facility.
Before Jayden Russell arrived in Lawrence on Sunday to move into his apartment with fellow Kansas football freshmen Gavin Potter, Valerian Agbaw and Kenny Logan, Russell didn't know all of the details of what awaited him and the numerous other newcomers officially joining the program this weekend.
Even so, Russell was sure of one thing.
"I just know we've got to get to work," Russell said during a recent interview with the Journal-World of the next couple of months leading up to the Jayhawks' preseason camp. "I don't know what we do or how much we do or things like that. But we're going to hit the ground running."
A 6-foot-3, 190-pound defensive back who helped lead St. Thomas Aquinas to a Class 5A state championship as a senior, Russell didn't enter his first week as a college student blindly, though.
Russell also knew Sunday would include a "whole bunch" of medical examinations, measurements and the like for the newest Jayhawks — "five or six hours" worth of those types of necessary orientation items were on the agenda, he estimated.
From there, based on what he had heard from KU football coaches and staffers, players would fully move their belongings into their new living spaces and then meet up for a family dinner. Russell also said the new arrivals would have meetings at KU's facility before summer classes and workouts begin on Tuesday.
Of course, the man in charge of the program, Les Miles, knew before all of his newest players got to town exactly what he would be telling them.
"The speech is: you're joining a community," Miles shared on Saturday. "It's an athletic community. It's a community of the town of Lawrence. And what we're expecting you to do is to adhere to our culture, make sure that they'll do the things in the weight room and on the football field that we want them to do, but also off the field be good students and be part of the community. Do the things to be responsible in the community eye."
Miles said KU's first preseason practice won't be until Aug. 1. However, newcomers and veterans alike will spend plenty of time between now and then going through strength and conditioning workouts, under the supervision of the team's staff members.
Said Miles: "We're going after it."
Russell projects as a safety as a freshman but based on the conversations he has had with various KU coaches over the past few months, he knows it's possible they could move him to another spot, perhaps cornerback or even outside linebacker.
"Just come in and work," Russell related of his new coaches' message to him. "Just with my body frame and things like that, they just want to see how my body grows."
At 6-3, Russell is the tallest defensive back on KU's entire roster.
"So I'm really excited about that," Russell said. "(The coaches) just want to see me work and see how everything goes."
Before he packed up and moved to Lawrence, Russell also spoke with some KU veterans about what to expect this summer as a freshman. He said he often talks with senior running back Khalil Herbert, who hosted Russell on his recruiting visit this past winter.
"It's a different culture," Russell shared of Herbert's words. "Things are so much different. Once you get in there, be ready to work hard, but also do the right things."
The freshmen coming in, Russell said, need to understand they will be held accountable for their actions. He said the whole program "did a 180" once Miles took over.
"Of course we want to be the best football team, but it starts off the field," Russell said. "You have to work hard off the field. Coach Miles really preaches that and every little detail matters. They just want you to work hard once you get here, and that's what the most of the guys are telling me. It's not going to be easy."
Russell said he has been training the past few months in preparation for not only this summer but the preseason camp that will follow it in August. His workouts came with the help of Johnny Beck, a former KU kicker who now helps athletes train.
"You've got to be mentally ready and also physically ready," Russell said of joining the collegiate ranks. "It's a different environment. Of course it's going to be tough, but once you get acclimated it's just football."

You have to appreciate Miles' approach to building a team while respecting the Lawrence and its citizens. In 4 years we can revisit the program's level of success on the field, but I for one like his approach regarding change the football culture in Lawrence. | RedPajamaCommonCrawl | test |

Walking out of Rick Springfield's very fun and truly enjoyable show with the Pacific Symphony on Thursday, I ended up next to two women who appeared to be fans of the rocker going back to his '80s heyday.
"Sixty-nine? He's 69?" one says to the other, loud enough to turn heads in the crowd. "He's so sexy!"
From there, the conversation dove into a discussion of Springfield's attributes so explicit my editor would faint if I included them here. Let's just say they had the same general idea other women who were shouting things like, "I want to have your baby!" at the singer throughout the show.
And let's face it, Springfield is one fit almost-septuagenarian. I heard at least one guy shouting out his love for Springfield during the show, too. And it wasn't me.
But the important thing to know is that Springfield is more than just a pretty boy of a certain age, for in a show that ran two hours including an intermission, he showed he's still got a lot more than a pretty face and "Jessie's Girl," his signature hit, to offer.
Here's what stood out at the Pacific Amphitheatre in Costa Mesa on Thursday.
1) A classy (bleepin') night: Springfield arrived on stage in a slim-cut burgundy tuxedo, his band dressed in black, the Pacific Symphony conducted by Albert-George Schram in white formal wear.
The opening number, "Affair Of The Heart," featured the strings to swell effect, and if not for all the plastic cups of beer that folks were swilling in the seats you might have almost thought this was a highbrow night out. Almost.
"Welcome to a night of (bleepin') culture!" Springfield announced at the end of that first number, the first of many times he playfully joked about a guy like him performing with an orchestra.
He and the musicians then moved into "I've Done Everything For You," a harder rocking number, and that and the next few tunes more or less drowned out the more delicate sounds of the symphony. But they played on every song in the show, and eventually the tunes and arrangements gave them more space to shine
A cover the Beatles' "She's Leaving Home" saw most of his band leave the stage — though his four backing vocalists were featured along with the orchestra — while "I Get Excited" was arranged for just Springfield and a string quartet. Both were highlights.
2. A sentimental guy: Springfield talked a lot between songs, explaining their origins and what they meant to him.
Early in the show, he sang "Souls," a deeper cut from his 1983 album "Living In Oz," a number written for his then-girlfriend, now-wife Barbara. A love song, it was followed by another she inspired. That one, "Don't Talk To Strangers," came from the same era, written as he was being "a bad boy out on the road in 1982," and was wrongly paranoid that she was being naughty at home.
Shortly before intermission, he paired songs written in tribute to his late mother and father, "Irreplaceable" for her, "My Father's Chair" for, well, that's an obvious one, right? Emotional ballads with photos of his parents on the video screen behind him, when he wiped his eyes at the end of the second number you felt it was genuine.
3. Chatter-boxing: Did we mention he talked a lot on Thursday? Springfield's long worked as an actor — and it was clear that his tenure as Dr. Noah Drake on the soap opera "General Hospital" in the early '80s was what brought a lot of these fans into his camp — and his ease on stage added to the fun of his performance.
"Oh, dude, popcorn?" he said at one point to a fan in the front row, helping himself to some of the guy's snacks. "I told you this was going to be a classy (bleepin') gig.

"My mom would have loved this except she wouldn't have been happy with me swearing: 'Richard, you've got to be a good example for the kids!'
"The kids are all in their 50s, mom! They've already decided if they want to swear or not."
Then, after choking for a moment on a piece of the caramel corn he'd snagged: "Note to self: When you're going to sing don't eat any friggin' popcorn!"
4. Rockin' out symphonically: After slower songs and ballads dominated the first set, the second half of the show found Springfield playing more electric guitar and songs like "Kristina" and "World Start Turning" rocking harder to build to the finish.
"You Better Love Somebody" and "Human Touch," a pair of his bigger hits, also rocked hard. The latter song saw him go into the crowd for an extended walk across the seats of fans during which he posed for selfies, offered high fives, and in the case of one overly enthusiastic guy, strap a watch on Springfield's wrist for some strange reason.
And then, of course, the big one. "Jessie's Girl," the song that if you only know one Springfield song you know. It featured two women crashing the stage to hug Springfield, a big crowd sing-along, and a warm finish to the night, that sent some fans home with visions of, well, we won't go there, but you heard what was on their minds at the start of this story.

Holds editorial responsibility for blog topics, is researching and writing articles. Her stories give insights into the world of the voestalpine Group.
voestalpine Wire Rod Austria GmbH is currently building the world's most state-of-the-art wire rolling mill at the Donawitz site. As part of this project, a cutting-edge, integrated logistics solution was developed for the production and storage of wire rods. This project recently received the VNL Logistics Award.
The wire rolling mill project
With the construction of the world's most state-of-the-art wire rolling mill at the Donawitz site, voestalpine Wire Rod Austria GmbH is investing in the future of the Donawitz location and has achieved a milestone in wire rod production. This project will reinforce voestalpine's technology leadership and develop new niche markets with innovative products. By mid-2016, the mill will be producing the first wire rod coils, weighing up to 3,000 kg, with extremely tight tolerances, extended dimensions of 5.00 mm to 60 mm, and appropriate heat and surface treatment.
This investment also includes a new logistics concept with a high-bay racking system that has a capacity of up to 18,000 tons for the storage of individual coils.
Complete logistics solution for the production and storage of wire rods
The integrated logistics solution comprises warehouse management, an application that locates the facility's fork lift trucks, material tracking, fully automated material flow control, a truck control system, as well as loading and dispatch. The fully automated high-bay racking system for the wire rod coils is the largest worldwide and is operated using special portal stacker cranes.
The implementation of the new logistics concept minimizes handling effort and expenditure in the warehouse, careful handling prevents damage to the products, and overall efficiency of logistics operations is doubled.
Honored by the VNL Logistics Award
At the Austrian Logistics Award 2015, the solution developed by voestalpine Wire Rod Austria GmbH was one of the finalists. This logistics award is given annually to companies that implement outstanding integrated overall logistics concepts. The award was presented by Verein Netzwerk Logistik (VNL) in the categories "Best Logistics Project" and "Best Innovative Logistics Solution." The jury particularly focused on the success of the project and its sustainability aspects. | RedPajamaCommonCrawl | test |
1,004,823 | Huawei Executive's Arrest Spooks China's Rich

New trends and breakthrough thinking in politics, science, technology, business and culture. It's futurism at its best.
Meng Wanzhou's arrest has sparked worries among Chinese business leaders about traveling to the U.S.
By Tom Mitchell
The Daily Dose DEC 18 2018
In August, a fu san dai, the Chinese term for "third-generation rich kid," discovered that his similarly wealthy friends in Beijing were taking a new precaution when traveling to the U.S. They would leave their usual smartphones and laptops behind in the Chinese capital and instead take "clean" replacements.
"They carry a second phone that has nothing on it," he explains. "They take the precaution of going in [to the U.S.] with a different phone. They leave the phone that they have in China and take a blank phone instead."
The fu san dai adds that he and his friends did not feel they had anything to hide. But as Sino-U.S. relations rapidly deteriorated over the summer, they heard more and more stories about friends — and friends of friends — being stopped by American "customs and border protection [agents] who would look through their electronic devices and see what was on their Facebook page or WeChat or whatever."
Four months later, Chinese elites have more to worry about than officious U.S. border agents. On Dec. 1, Meng Wanzhou, the daughter of one of China's most celebrated entrepreneurs, was detained in Canada at the request of American prosecutors. She is wanted in the U.S. for alleged bank fraud related to evasion of U.S. sanctions against Iran.
All Chinese … need to stick together and raise high the banner of patriotism.
Sima Nan, Chinese nationalist commentator
Ren Zhengfei, Meng's father, is the founder of privately held Huawei, which over three decades has become one of the world's largest manufacturers of telecommunications network equipment and smartphones. Meng, who was released on bail by a Vancouver judge last week, is a Huawei deputy chairwoman and also its chief financial officer.
To put the incident's shock value in an American context, it was as if a daughter of Steve Jobs, who was following him up the corporate ladder at Apple, had been detained in Moscow pending her possible extradition to Beijing.
Ren is a former Chinese military officer who left the People's Liberation Army in the 1980s to establish Huawei. Because of his background, as well as Huawei's global reach and an opaque employee-ownership structure, the company has never been able to shake U.S. concerns that its equipment posed a security risk to Western governments.
Ren, while doubted abroad, is adored at home. "Almost all the Chinese entrepreneurs I meet have huge respect for what Huawei has done within China and on the global stage," says Rupert Hoogewerf, publisher of Hurun Report, the country's most authoritative rich list. "He's talked about almost in hushed tones."
The reverberations from Meng's legal case are being felt across China. "We always knew Canada is America's running dog and will block Chinese acquisitions of Canadian tech companies [on national security grounds]," says a senior executive at one of China's largest state-owned technology groups. "But this came as a total surprise."
The executive adds that he and his colleagues did not fear suffering the same fate as Meng. Few Chinese companies are as squarely in the U.S. government's crosshairs as Huawei. But Meng's arrest has only reinforced a conclusion his company came to in 2017: It is futile to try to buy U.S. or Canadian technology companies. His group now focuses its acquisition efforts almost entirely on European and Israeli targets, usually below what he calls a "political threshold" of $300 million to avoid government and media scrutiny.
Sima Nan, a prominent nationalist commentator, calls the incident "yet another example of U.S. hegemonism and imperialism," adding that it reminded "all Chinese of the need to stick together and raise high the banner of patriotism."
A Chinese vice foreign minister had summoned both the Canadian and U.S. ambassadors to express his government's outrage over Meng's arrest. But in its public comments, the Chinese government has been careful to train most of its fire at Ottawa rather than Washington.
Angry though Chinese officials may be, their top foreign policy priority is a negotiated end to the trade war with the U.S. They do not want Meng's case to derail trade talks with the Trump administration.
Within 10 days of Meng's arrest, Chinese authorities detained at least two Canadian citizens for allegedly "harming China's national security," with no confirmed cases of any similar reprisals against U.S. nationals. There has been no official confirmation that the detention of the Canadians — Michael Kovrig and Michael Spavor — and that of Meng are connected.
Most commentators on China's tightly monitored social media platforms have stuck to the government's anti-Ottawa script. "China's countermeasures should not stop," Han Dongyan told his more than 600,000 followers on Sina Weibo, the country's equivalent of Twitter. "China should make Canada pay a heavy price for insulting an innocent Chinese national." In Han's view, Meng has been "kidnapped."
The contrast between Meng's detention and the disappearances of Kovrig and Spavor could not be more stark. Meng has appeared with her lawyer before an independent judge in an open court packed with journalists. She was granted bail and allowed to return to one of her two Vancouver homes, which have a combined value of at least $14 million Canadian dollars ($10.5 million).
Such luxurious bolt-holes — and the overseas educational opportunities they have provided for her three children — might make Meng seem an unlikely national hero. During her bail hearing, her lawyer showed the court photos of Meng's family enjoying British Columbia's pristine environment.
Most ordinary Chinese do not appear to begrudge Meng doing what they would do too if they could. Indeed, tens of thousands of well-off mainland Chinese families have done the same. According to Vancouver's 2016 census, ethnic Chinese residents account for 20 percent of the city's 2.4 million people.
"I am back with my family," Meng wrote on her WeChat account after being released on bail. "I am proud of Huawei and I am proud of my motherland. Thank you all for your concern."
Below her comments she posted a Huawei advertisement depicting a ballerina's bruised feet with the tagline: "Behind greatness there is suffering."
Kovrig and Spavor, on the other hand, have disappeared into China's state security apparatus, where they enjoy none of the legal protections afforded to Meng. Their social media feeds have gone silent.
