Usher | Effects of War on America | The New York Times Current History of the European War | http://www.gutenberg.org/files/16702/16702-h/16702-h.htm | 1,915 | Info | Lit | 1,300 | start | null | PG | 2 | 2 | The events of the last few days of July 1914, showed the Americans the far-reaching effects of a state of war. There are now few who would say, as used to be so common, that a European war would make no difference to us. The closing of the New York Stock Exchange, the great shipments of gold and its consequent scarcity in the United States, the closing of the New England cotton mills, the cessation of export to Europe and of transatlantic communication with the Continent were instantaneous effects of a war 3,000 miles away obvious even to the apathetic and the heedless. With these we have not here to do; such are already past history. There is, however, a legitimate field for speculation as to the probable effects on the United States of the continuation of the state of war in Europe for months or years. The permanent results of a war naturally cannot be predicted in advance, but in the light of the history of the past, certain changes and developments in the United States appear so probable if the war continues as to reach almost the realm of certainty. | 192 | 6 | 1 | -1.192858 | 0.487036 | 47.51 | 14.62 | 15.73 | 15 | 8.75 | 0.33295 | 0.32235 | 13.121 | 2,155 |

But it is clear that they should differ in some respects: left-handers use their hands (and feet) differently than right-handers do, and they do this often over the course of a lifetime. It is only natural that the parts of the brain that control movements should be different in left-handers and right-handers. Compare this to skilled musicians: they practice fine movements a lot, and this influences their brains. To study exactly how the brains of left- and right-handers differ, we need to look at brain lateralization.
Brain lateralization refers to the fact that the left and right sides of the brain are not the same. The two sides differ in their anatomy, and also in what they do. By the way, lateralization is also found in the rest of the body: the two arms look slightly different, and are capable of doing different things; the heart is lateralized to one side of the body cavity, etc. Left-handers are distinct from right-handers in that they tend to have less lateralization in the brain. | 188 | 9 | 2 | -0.443453 | 0.471147 | 63.16 | 9.92 | 10.95 | 11 | 7.84 | 0.1932 | 0.18843 | 27.824689 | 1,712 |

The information itself can be stored in many different ways - before digital computers, card files, printed books and other methods were used. Now most data is kept on computer files.
A database system is a computer program for managing electronic databases. A very simple example of a database system would be an electronic address book.
The data in a database is organized in some way. Before there were computers, employee data was often kept in file cabinets. There was usually one card for each employee. On the card, information such as the date of birth or the name of the employee could be found. A database also has such "cards". To the user, the card will look the same as it did in old times, only this time it will be on the screen. To the computer, the information on the card can be stored in different ways. Each of these ways is known as a database model. The most commonly used database model is called relational database model; it uses relations and sets to store the data. | 190 | 14 | 3 | -0.622843 | 0.468447 | 62.32 | 7.96 | 6.49 | 12 | 8.36 | 0.26354 | 0.23633 | 21.335058 | 460 |

For example, a box is three-dimensional; it is solid, and not thin like a piece of paper. It has volume, a top and bottom, left and right (sides), as well as a front and back. You can turn the box around to view it from another side (called a face, surface or simply side).
A dimension is measurable in inches, microns, miles, kilometers, or any other unit of length.
The three dimensions are often called length (or depth), width (or breadth), and height. Some purposes use other words.
3D graphics are used to make video games or animated movies. Many calculations are needed to make pictures seem three-dimensional on a screen. Modern computers usually have a GPU (Graphics Processing Unit) to handle these calculations.
Binocular vision helps people to see the third dimension easily.
In the Cartesian coordinate system, length, width, and height are given in letters (variables) to make them easier to write, or if a value is not known. Often X is width, Y is height, and Z is length. Other 3D coordinate systems such as spherical coordinates include both linear and angular measurements. | 190 | 14 | 6 | -0.838837 | 0.463235 | 63.17 | 7.98 | 7.35 | 11 | 8.78 | 0.28487 | 0.23819 | 14.995108 | 911 |

When Havelok heard who was lord of that part of Denmark, he was glad, and set out to go to Ubbe's castle in good hope. He dared not say yet that he was Birkabeyn's son, for if Earl Godard heard of it, he would come against him and slay him before he could win any followers. But he went to Ubbe and spoke him fair and courteously, and gave him a gold ring, and asked leave to settle in that land to be a merchant; and Ubbe, seeing how strong and comely Havelok was, gladly gave him leave, and thereafter bade him to a great feast. Havelok went to the feast, and Goldborough with him, and Grim's sons also; and Ubbe grew to love him so well that when the feast was ended, he sent him with ten knights and sixty men-at-arms to the magistrate of those parts, Bernard Brun, a man of might and substance. | 183 | 5 | 2 | -2.415775 | 0.561062 | 64.46 | 13.51 | 16.13 | 12 | 8.45 | 0.04357 | 0.04651 | 18.386359 | 328 |

They saw nothing but mantles of green covering all the field; then every man began saying to another: "I dread our king is slain; if Robin Hood comes to the town, he will never leave one of us alive. "They all hastened to make their escape, both men and lads, yeomen and peasants; the ploughman left the plough in the fields, the smith left his shop, and old wives who could scarcely walk hobbled along on their staves.
The king laughed loud and long to see the townsfolk scurry off in this fashion, and he commanded them to come back. He soon let them understand that he had been in the forest, and that from that day for evermore he had pardoned Robin Hood. When they found out the tall outlaw in the Lincoln green was really the king, they were overjoyed; they danced and sang, and made great feasting and revelry for gladness at his safe return. | 169 | 6 | 2 | -1.541347 | 0.478166 | 71.58 | 10.31 | 12.94 | 9 | 7.36 | 0.11994 | 0.13639 | 13.972723 | 343 |

Gamification commonly employs game design elements which are used in so called non-game contexts in attempts to improve user engagement, organizational productivity, flow, learning, employee recruitment and evaluation, ease of use and usefulness of systems, physical exercise, traffic violations, and voter apathy, among others. A review of research on gamification shows that a majority of studies on gamification find positive effects from gamification. However, individual and contextual differences exist. Gamification uses an empathy-based approach (such as design thinking) for introducing, transforming and operating a service system that allows players to enter a gameful experience to support value creation for the players and other stakeholders. Gamification designers address the user as player to indicate that the motivations and interests of the player are in the center of the gamification design. | 142 | 6 | 1 | -2.243349 | 0.495231 | 9.46 | 17.98 | 18.15 | 17 | 11.87 | 0.3748 | 0.38238 | 1.289615 | 539 |

Having said this, depending on how old you are, you may still have to wait a while until you have your first déjà vu experience. A very small number of people say they had their first déjà vu experience by the age of 6. More people report their first déjà vu experiences as having happened sometime before they were 10 years old. The reason it may take a while to have your first déjà vu experience is that you need to be able to work out whether the feeling of familiarity you have really is stronger than it should be. For many younger kids, this may be a tricky thing to do.
By the time you reach an age between 15 and 25, you will probably be having déjà vu experiences more often than you will ever have them after that. The number of déjà vu experiences people report steadily decreases after 25 years old. This is puzzling for researchers because we are used to thinking of memory problems increasing with age, not decreasing with age! | 182 | 9 | 2 | 0.115479 | 0.522876 | 67.85 | 8.85 | 8.75 | 10 | 7.92 | 0.04992 | 0.0368 | 30.142037 | 1,585 |

The few people she met turned to look at her, as if it was a pleasant sight to see a hearty, happy girl walking countryward that lovely day; and the red-faced young man steaming along behind, hat off and every tight curl wagging with impatience, evidently agreed with them.
Presently a mild 'Hallo!' was borne upon the breeze, and pausing, with an effort to look surprised that was an utter failure, Nan said affably:
'Oh, is that you, Tom?'
'Looks like it. Thought you might be walking out today'; and Tom's jovial face beamed with pleasure.
'You knew it. How is your throat?' asked Nan in her professional tone, which was always a quencher to undue raptures.

In telephonic central offices, M. Bede has seen all the signals of one row of telephone wires fall at the same moment, proving that an electric discharge had fallen upon the wires, and been by them conveyed to earth.
This fact shows that wires, even without points, are capable of attracting the atmospheric electricity; but it must be remembered that there are two points at every join in the wire. M. Bede insists strongly upon the uselessness of terminating lightning conductors in wells, or even larger pieces of water. The experiments of MM. Becquerel and Pouillet proved that the resistance of water to the passage of electricity is one thousand million times greater than that of iron; consequently, if the current conveyed by a wire one square mm. thick were to be carried off by water without increased resistance, a surface of contact between the wire and the water of not less than 1,000 square meters must be established. | 177 | 7 | 2 | -3.596751 | 0.56705 | 52.7 | 12.23 | 13.57 | 12 | 8.18 | 0.17871 | 0.17741 | 10.791031 | 3,047 |

When asked as to the future, they reply that they will do all in due time. After Belgium will come France, and then the turn of England will arrive. They are not discouraged by the failure to reach Paris, since the strategy adopted by the French would have rendered the possession of Paris of little value. It will still be taken.
With regard to England not much is said of an army of invasion, but German confidence is evidently reposed in her Zeppelins, of which a large number is being constructed with all possible speed. They are to be employed against England, whose part in the war is the least honorable of all. Belgium's attitude at the outset they can understand, France's desire for la revanche is natural, but England's only motive was jealousy of Germany's industrial development and the desire to cripple her trade and commercial prosperity.

A fragment of the Babylonian flood story, coming from at least as early as 2000 B.C., has recently been discovered. The probability is that the tradition goes back to the earliest beginnings of Babylonian history. The setting of the Biblical accounts of the flood is also the Tigris-Euphrates valley rather than Palestine. The description of the construction of the ark in Genesis 6:14-16 is not only closely parallel to that found in the Babylonian account, but the method—the smearing of the ark within and without with bitumen—is peculiar to the Tigris-Euphrates valley. Many scholars believe, therefore, that Babylonia was the original home of the Biblical flood story.
Its exact origin, however, is not so certain. Many of its details were doubtless suggested by the annual floods and fogs which inundate that famous valley and recall the primeval chaos so vividly pictured in the corresponding Babylonian story of the creation.

An actual energy (E = hf) is a nonzero-frequency angular momentum.
A potential energy is the zero-frequency angular momentum stored in a potential flow of the vacuum.
The potential fields are irrotationally radial ("electric") fluxes of the vacuum and divide into two classes:
The gravitoelectric fields;
The electric fields.
The potential energy is negative. It is not a mere convention but a consequence of conservation of energy in the zero-energy universe—as an object descends into a potential field, its potential energy becomes more negative, while its actual energy becomes more positive.
In accordance with the minimum total potential energy principle, the universe's matter flows towards the minimum total potential energy. This cosmic flow is time. | 136 | 8 | 8 | -2.830374 | 0.526537 | 31.78 | 12.83 | 11.01 | 16 | 11.84 | 0.31871 | 0.32689 | 11.203506 | 765 |

No great man ever lived that was not a patriot in the highest and truest sense. From the earliest times, the sentiment of patriotism has been aroused in the hearts of men by the narrative of heroic deeds inspired by love of country and love of liberty. This truth furnishes the key to the arrangement and method of the present work. The ten epochs treated are those that have been potential in shaping subsequent events; and when men have struck blows for human liberty against odds and regardless of personal consequences. The simple narrative carries its own morals, and the most profitable work for the teacher will be to merely supplement the narrative so that the picture presented shall be all the more vivid.

The work to be done by a fan consists in putting a weight--that of the air--in motion. The resistances incurred are due to the inertia of the air and various frictional influences; the nature and amount of these last vary with the construction of the fan. As the air enters at the center of the fan and escapes at the circumference, it will be seen that its motion is changed while in the fan through a right angle. | 194 | 8 | 2 | -1.759132 | 0.497073 | 72.33 | 9.29 | 9.86 | 10 | 8.22 | 0.25461 | 0.24646 | 17.033411 | 2,849 |

Well, this charming little pet was of a light yellowish-brown color, and over his whole body were white spots about the size of a dime.
Some boys had surprised him asleep, when he was about a week old, and had carefully taken him home with them. There he had been tended and made much of by the whole family, and so he had grown to have a genuine affection for his captors.
He was allowed full freedom to go about the woods as he chose, and never failed to return at night; and when called by name—for the boys had named him Dick—he would come bounding up as if he dearly loved to be petted. | 161 | 6 | 4 | -0.194721 | 0.469728 | 81.3 | 7.07 | 7.14 | 7 | 5.9 | -0.00269 | 0.01476 | 19.511055 | 2,953 |

The method in common use, and which may be called the natural method, is to devote a separate drawer to the drawings of each machine, or of each group or class of machines. The fundamental idea of this system, and its only one, is, keeping together all drawings relating to the same subject matter.
Every draughtsman is acquainted with its practical working. It is necessary to make the drawing of a machine, and of its separate parts, on sheets of different sizes. The drawer in which all these are kept must be large enough to accommodate the largest sheets. The smaller ones cannot be located in the drawer, and as these find their way to one side or to the back, and several of the smallest lie side by side in one course, any arrangement of the sheets in the drawer is out of the question. | 182 | 7 | 3 | -2.138277 | 0.477507 | 55.55 | 12.04 | 12.77 | 12 | 7.34 | 0.25827 | 0.26242 | 16.511334 | 2,955 |

Some edible oils and syrups are also made from corn, such as fructose and other sweeteners, used in most sodas or even juices sold in supermarkets. Processed corn is also used in medicines, cosmetics, glues, paper, textiles, paints, and solvents. Corn residues or "scraps" have recently been used to create biodegradable materials similar to plastics. Another use for corn is to use its sugars to make biodiesel fuel for use in cars and other vehicles.
So, not only can we eat corn as an additive mixed into different foods, or as a side dish like delicious corn on the cob, or grits, or as a snack in the form of nachos and popcorn: around the world, there are many dishes—and cultures—that totally revolve around corn.

Several evenings, when Susan was alone in the house, he "scared her stiff," as she declared, by doing this. He would sit in the middle of the kitchen floor, with his terrible eyes fixed unwinkingly upon hers for an hour at a time. This played havoc with her nerves, but poor Susan really held him in too much awe to try to drive him out. Once she had dared to throw a stick at him and he had promptly made a savage leap towards her.

Broadly speaking, viruses are made of two things, proteins and nucleic acids (nucleic acids are the stuff that genes are made of). The proteins make a coat around the genes and this coat protects them from the environment and helps the virus to infect cells. There are multiple types of flu virus and we categorize these types based on the two proteins that appear on the surface of the virus. These two proteins are called hemagglutinin and neuraminidase. These proteins are assigned a number based on their specific shape, giving us many combinations, for example H1N1 or H5N1. These different combinations of proteins on the surface of the flu virus have an important impact on which animal species the flu virus infects. For example, there is a chicken virus (H5N8) causing infections in bird populations in Europe in 2017, but this virus is unlikely to cause illness in people. | 173 | 8 | 1 | -0.426743 | 0.51739 | 57.97 | 10.61 | 12.07 | 11 | 9.95 | 0.32059 | 0.31143 | 9.265386 | 1,355 |

A mass of cold metal placed in the oven is instantly bedewed with moisture, which dries up as the temperature of the metal rises. This is, for many purposes, an objection, and the remedy is to close the bottom of the oven and place burners underneath. If for drying purposes and a current of air is necessary, the simplest way is to place in the bottom of oven the a number of tubes hanging downward in such a position that the heat of the flame acts both on the bottom of the oven and the sides of the tubes, which, of course, must be long enough for the lower opening to be well below the level of the flame. The exit may be at any level, but for drying purposes it is better at the top, and it should be controlled by a damper to prevent cooling by excessive currents of air. | 196 | 6 | 1 | -2.01784 | 0.541235 | 54.98 | 13.71 | 14.58 | 12 | 8.4 | 0.27203 | 0.26944 | 10.967817 | 2,688 |

They are usually triggered by the saturation of thickly vegetated slopes which results in an incoherent mixture of broken timber, smaller vegetation and other debris. Debris avalanches differ from debris slides because their movement is much more rapid. This is usually a result of lower cohesion or higher water content and commonly steeper slopes.
Steep coastal cliffs can be caused by catastrophic debris avalanches. These have been common on the submerged flanks of ocean island volcanos such as the Hawaiian Islands and the Cape Verde Islands. Another slip of this type was Storegga landslide.
Debris slides generally start with big rocks that start at the top of the slide and begin to break apart as they slide towards the bottom. This is much slower than a debris avalanche. Debris avalanches are very fast and the entire mass seems to liquefy as it slides down the slope. This is caused by a combination of saturated material, and steep slopes. | 179 | 11 | 3 | -1.470831 | 0.53284 | 55.52 | 9.6 | 9.92 | 11 | 9.6 | 0.26962 | 0.25006 | 7.763293 | 638 |

The word nation comes from a word meaning "birth" or "place of birth." The adjective is national .
Some nations are people with a particular belief, such as the Vatican City, or ethnic group, such as Armenia. Others share an idea, such as Democracy in the United States or Communism in China.
Some nations are controlled by a small minority who have all the power, such as Saudi Arabia, who hold the nation together with the use of this power.
Some of these may also be combined. The highest lawful authority of most nations is a constitution, which is a document which states clearly what kinds of power the rulers have and how new laws must be made. Many others are ruled by a single person who holds an "office" (position), such as a King or Pope, or from a long legal tradition without an official Constitution, such as the United Kingdom. | 178 | 10 | 5 | -0.049815 | 0.482689 | 59.93 | 9.4 | 8.53 | 11 | 8.02 | 0.17891 | 0.1651 | 13.647593 | 707 |

The current can also be increased to make the magnetism stronger. British electrician William Sturgeon invented the electromagnet in 1825.
An electromagnet is useful because it can be turned on and off easily (using an electric current), whereas a permanent magnet cannot be turned off and will continue to affect its immediate environment.
Different alloys act differently. Iron stops being an electromagnet very quickly, but steel takes time to wear off. To make an electromagnet, copper wire is wound around an iron rod. The two ends of the wire are connected to the + (positive) and - (negative) side of the battery.
Electromagnets are used in everyday items such as burglar alarms, electric relays and fire bells. Electric motors are basically electromagnets. Their ability to change from the state of non-magnetic to magnetic just by passing an electric current through it allows it to be used in many different items. This ability is used in relays. | 178 | 12 | 4 | -1.009733 | 0.464928 | 46.85 | 10.45 | 9.4 | 12 | 8.5 | 0.25148 | 0.22998 | 12.185381 | 972 |

It does not refer to everything everybody thinks or does, but only to those things that everybody acts upon – or refuses to do – quite reliably.
Because it must keep even the poorest and weakest members of a society willing to help even the richest and strongest, a society is very concerned with its citizenship, rights, ethics and time limits. These are basic ways to achieve fairness. If they break down badly, people will think the society is unfair and start taking things from each other, refusing to help each other, or seeing those who have more as cheats.
While every society is different, the way it breaks down and fails is very often the same: fraud, theft, violence, war and sometimes even genocide if people stop identifying with the society and thus identify with what they think of as a "race" of people. A new society may be formed out of only those who still agree, or who just survive the collapse of an old failed one. | 186 | 7 | 3 | -0.698004 | 0.477325 | 53.42 | 12.41 | 13.34 | 12 | 7.76 | 0.21778 | 0.19914 | 16.760597 | 822 |

This current is sometimes called the global conveyor belt, for the way it circulates water all around the globe. If water could be tracked on its journey on the global conveyor belt, following the red path as warm water nears the surface, then cools and sinks to follow the blue path until it comes back to the surface again, we would find that it takes the water around 1,000 years to complete its travel all the way around the world.
An obvious first guess as to what might cause this motion in the ocean is the wind. Wind blows over the ocean's surface, causing both waves and movement of water in a downwind direction.

The greenhouse effect is caused by greenhouse gases; the most important greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, and methane. When there is more greenhouse gas in the air, the air holds more heat. This is why more greenhouse gases cause global warming.
The greenhouse effect is natural. It is important for life on Earth. Without the greenhouse effect, the Earth's average temperature would be around -18 or -19 degrees Celsius (0 or 1 degree Fahrenheit). Earth would be locked in an ice age. Because of the greenhouse effect, the Earth's actual average temperature is 14 degrees Celsius (57 degrees Fahrenheit).
The problem is that recently, the greenhouse effect has become stronger. This is because humans have been using large amounts of fossil fuels, which release carbon dioxide when they are burned. | 167 | 12 | 4 | -0.281876 | 0.501788 | 63.57 | 7.91 | 9.49 | 9 | 10.28 | 0.27011 | 0.2566 | 19.226058 | 561 |

Research and development is a component of Innovation and is situated at the front end of the Innovation life cycle. Innovation builds on R&D and includes commercialization phases.
The activities that are classified as R&D differ from company to company, but there are two primary models, with an R&D department being either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields which may facilitate future product development. In either case, R&D differs from the vast majority of corporate activities in that it is not often intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. | 145 | 5 | 2 | -1.657824 | 0.472398 | 20.17 | 17.7 | 19.1 | 18 | 12.11 | 0.35131 | 0.36244 | 9.103277 | 791 |

The next thing was to find a name, "pretty, and not too common," Alice said. While she was trying to think of one, she went up to her own little room and searched among her ribbons for a piece to tie around the kitten's neck. She soon found one that was just the thing.
In one of her drawers, she found a tiny bell that somebody had given her and thought it would be a good plan to hang that around kitty's neck by the ribbon.

This would be of immense advantage to the future of civilization and ensure us against the horrors of a prolonged war. A separate peace would be the best chance for certain Powers to change their international policy. To my mind the issues of this war will greatly change the attitude of some hostile States toward us, and will bring about more intimate relations between them and ourselves, besides widening the foundations of the alliance between Hungary and her allies. And this is to be the rock upon which the European balance of power is to rest in the future.

These poles stay in the same place and are usually the ones we mean if we just say North or South Pole. People can tell that they are at these poles by looking at the stars (at the poles, a star just circles around at the same height, never dipping to the horizon). The Sun rises once a year and gives the South Pole half a year of summer, but it is always cold. When the Sun sets half a year later it makes half a year of winter which is even colder.

But do you know that the plants and animals around us also have languages that allow them to "talk" to each other? Both land and water plants and animals have a special chemical "language" that they use to communicate. These communication chemicals are called info-chemicals (information-carrying chemicals). When a bee visits a flower, it is not just random! The flower releases info-chemicals that the bee can sense, which invite the bee to visit the flower and help the flower to pollinate. So, the next time you see a bee visiting a flower, maybe you will think about the role that info-chemicals play for the beautiful flowers around us.
What about marine animals and plants, those that live in the oceans? We know that some marine animals communicate using sounds, like the dolphins producing clicking sounds or the singing of whales, but this is not the only way for marine organisms to talk to each other. Marine organisms mostly talk to each other using info-chemicals, which are known as the "language of life" in the sea. | 184 | 10 | 2 | -0.346338 | 0.503995 | 58.87 | 9.77 | 10.07 | 11 | 7.24 | 0.14543 | 0.13962 | 20.563862 | 1,046 |

This resin is a very beautiful red substance, which communicates its peculiar color to the leather.
We should mention here that in these calculations we assume that the hide is in a perfectly dry state, water being a changeable element which does not allow one to arrive at a precise result.
These figures show the enormous differences resulting from diverse methods of tanning. Hemlock, which threatens to flood the markets of Europe, distinguishes itself above all. The high results attributable to the large proportion of resin that the hide assimilates, explain in part the lowness of its price, which renders it so formidable a competitor. One is also surprised at the large return from sumac-tanned hides when it is remembered in how short a time the tanning was accomplished, which, in the present case, only occupied half an hour.
The figures show us that the greatest return is obtained by means of those tanning substances which are richest in resin. In short, hemlock, sumac, and pine, which give the greatest return, are those containing the largest amount of resin. | 191 | 9 | 4 | -2.913002 | 0.534775 | 52.65 | 11.33 | 12.74 | 12 | 8.34 | 0.32883 | 0.30893 | 6.606611 | 3,022 |

If for heating boilers, furnaces, etc, coke or any kind of coal maybe used; but for gas engines or any application of the gas requiring great cleanliness and freedom from sulphur and ammonia it is best to use anthracite, as this does not yield condensable vapors, and is very free from impurities. Good qualities of this fuel contain over 90 per cent of carbon and so little sulphur that, for some purposes, purification is not necessary. For gas engines, etc., it is, however, better to pass the gas through some hydrated oxide of iron to remove the sulphureted hydrogen. The oxide can be used over and over again after exposure to the air, and the purifying is thus effected without smell or appreciable expense. Gas made by this process and with anthracite coal has no tar and no ammonia, and the small percentage of carbon dioxide present does not sensibly affect the heating power. | 170 | 6 | 1 | -1.561415 | 0.474681 | 52.8 | 11.93 | 12.36 | 13 | 9.11 | 0.19213 | 0.19356 | 10.061088 | 3,017 |

The Americans were led by General Horatio Gates. The British were led by General John Burgoyne. On October 17 Burgoyne surrendered his army of nearly 6,000 British soldiers. The American victory helped convince France to come to the aid the Continental Army. It also helped them recognize the United States.
In early 1777, General William Howe asked London to approve his plan to attack Philadelphia. This would destroy the rebel American government. In Canada, General John Burgoyne submitted a plan to move down through New York and meet General Howe at Albany. This would divide the colonies. London approved both plans. Burgoyne began moving down the Hudson River valley from Canada. He split his force into two columns. One, under Colonel Barry St. Leger moved east from Lake Ontario down the Mohawk Valley. They attacked the Americans at Fort Stanwix.

Ultimately, research in neuroethics seeks to identify solutions to help neuroscience and society come together safely and with the best results.
Research in neuroethics breaks down into four main areas of study. To provide a better understanding of each of these areas, we highlight four examples of neuroethics research from each of the four categories.
The term cognitive enhancement refers to the improvement of thinking skills when there is not an inherent problem with thinking. Several medications have been created to help people with thinking problems improve their ability to concentrate and do better in school. Sometimes, however, healthy people also use these medications because they want to improve their memory or ability to learn as well. This is called cognitive enhancement, and neuroethicists have raised four concerns related to this practice. | 176 | 9 | 3 | -1.686058 | 0.500361 | 40.14 | 12.55 | 13.61 | 14 | 9.61 | 0.21883 | 0.20713 | 17.372146 | 1,573 |

Enzymes have names which show what they do. Enzyme names usually end in –ase to show that they are enzymes. Examples of this include ATP synthase. It makes a chemical called ATP. Another example is DNA polymerase. It reads an intact DNA strand and uses it as a template to make a new strand.
One example of an enzyme is amylase, found in saliva. It breaks down starch molecules into smaller glucose and maltose molecules. Another kind of enzyme is lipase. It breaks down fats into smaller molecules, fatty acids and glycerol.
The proteases are a whole class of enzymes. They break down other enzymes and proteins back into amino acids. Nucleases are enzymes that cut DNA or RNA, often in specific place in the molecule.
Enzymes are not only for breaking large chemicals into smaller chemicals. Other enzymes take smaller chemicals and build them up into bigger chemicals, and do many other chemical tasks. | 169 | 16 | 4 | -1.684292 | 0.470707 | 64.11 | 6.99 | 6.35 | 10 | 9.59 | 0.30799 | 0.29636 | 17.402195 | 506 |

You would live with your mother, father, brothers and sisters in a group. This group is called a pack. Other wolves would live in the pack, too.
You would like to play with your brothers and sisters. This would teach you how to hunt. Your pack would hunt together. You might hunt caribou, rabbits, and musk oxen.
Your life would be hard. Hunting is dangerous. You might not be able to find food. Then you would be hungry.

In its Greek origin the word has no negative meaning: we translate Oedipus Tyranos as 'Oedipus the King'. A tyrant usually rules a country, and he often got his position as powerful ruler by force, although some of them inherited their power.
Later, the word came to mean someone who ruled with cruelty and injustice. The rule of a tyrant is called tyranny. The adjective is tyrannical.
A dictator or despot is someone who rules with absolute authority, usually cruelly. It now has the same meaning as 'tyrant', whereas before, 'tyrant' meant something like 'ruler' or 'king'.
In the 10th and 9th centuries BC, Ancient Greece was ruled by monarchs. By the 7th century BC, they were ruled by groups of aristocrats. These aristocrats started to become unpopular. This gave cruel people the chance to get power for themselves, telling the people that they would be good rulers, but turning bad once they got power.
Around 650 BC the tyrant Cypselus became powerful in Corinth. | 173 | 13 | 5 | -0.426009 | 0.445915 | 63.7 | 7.53 | 7.06 | 10 | 8.97 | 0.22973 | 0.21834 | 13.564268 | 1,514 |

This Caliban, Prospero found in the woods, a strange misshapen thing, far less human in form than an ape: he took him home to his cell, and taught him to speak; and Prospero would have been very kind to him, but the bad nature which Caliban inherited from his mother Sycorax, would not let him learn anything good or useful: therefore he was employed like a slave, to fetch wood, and do the most laborious offices; and Ariel had the charge of compelling him to these services.
When Caliban was lazy and neglected his work, Ariel (who was invisible to all eyes but Prospero's) would come slily and pinch him, and sometimes tumble him down in the mire; and then Ariel, in the likeness of an ape, would make mouths at him. | 173 | 3 | 2 | -2.131611 | 0.497781 | 27.39 | 23.85 | 28.12 | 18 | 9.6 | 0.2749 | 0.2749 | 15.733946 | 4,381 |

And early on I made another choice, which I hope you'll make as well. Whether you are talking about education, career, or service, you're talking about life — and life really must have joy. It's supposed to be fun.
One of the reasons I made the most important decision of my life, to marry George Bush, is because he made me laugh.

To his nephew, Talus, or Perdrix, he taught all that he himself knew of all the mechanical arts. Soon it seemed that the nephew, though he might not excel his uncle, equaled Dædalus in his inventive power.

The term electronic engineering started to emerge in the late 1950s. Before the second world war, electronic engineering was commonly known as a 'radio engineering'. At that time, studying radio engineering at a university was part of a physics degree. Later, as consumer devices started to be developed, the field broadened to include modern TV, audio systems, Hi-Fi and later computers and microprocessors. In the mid to late 1950s, the term radio engineering gradually gave way to the name 'electronic engineering', which then became a standalone university degree subject. Fundamental studies of the discipline are the sciences of physics and mathematics as these help to get both qualitative and quantitative descriptions of how such systems will work. | 172 | 8 | 1 | -1.011278 | 0.479459 | 28.4 | 14.67 | 15.28 | 15 | 11.01 | 0.31313 | 0.29564 | 8.489953 | 1,323 |

They define who we are and how we experience the world. During learning, in a process called memory allocation, a group of active neurons are selected to serve as the cells that "hold" a specific memory. These cells will tend to be active together from that time forward, so that each time this memory is recalled, this chosen group of neurons will be reactivated. Therefore, recalling a memory depends on the reactivation of the same group of cells that were activated at the time the memory was made.
Memory disruption is relatively easy to induce in the lab, but what most of us really want, even if our memory is perfectly normal, is to make it even better. This aspiration for memory improvement has challenged scientists for many years. Most attempts to improve memory focus on strengthening the connections between neurons or boosting the formation of memories.
Is it possible that astrocytes can sense the neuronal activity around them and use this information to improve the flexibility of neuronal communication and possibly improve memory? | 185 | 9 | 3 | -1.342049 | 0.457267 | 41.43 | 12.64 | 12.42 | 15 | 9.48 | 0.3063 | 0.28927 | 17.070464 | 799 |

Like life in a desert, life in the tropical ocean is difficult for all organisms. Yet, coral reefs are colorful oases full of life in the middle of this marine desert. How can millions of species call coral reefs their home? All organisms living there play their roles in recycling the small amounts of food and nutrients that are available. Because nothing is ever truly wasted, coral reefs can flourish in a marine desert that has hardly any food. Although coral reefs existed on this planet long before the dinosaurs, they are facing serious problems today. Warming oceans can harm corals, leading to the loss of coral reefs. However, corals in the northern Red Sea are very resistant to warm temperatures. Some scientists believe that these Red Sea reefs may be able to survive even when reefs are disappearing elsewhere around the world. | 152 | 10 | 1 | 0.991114 | 0.55908 | 60.05 | 8.66 | 9 | 10 | 8.86 | 0.2431 | 0.23795 | 17.123709 | 1,081 |

No wonder, therefore, that poor Daffydowndilly found it a woeful change to be sent away from the good lady's side and put under the care of this ugly-visaged schoolmaster, who never gave him any apples or cakes, and seemed to think that little boys were created only to get lessons.
"I can't bear it any longer," said Daffydowndilly to himself, when he had been at school about a week. "I'll run away and try to find my dear mother; and, at any rate, I shall never find anybody half so disagreeable as this old Mr. Toil!"
So the very next morning, off started poor Daffydowndilly, and began his rambles about the world, with only some bread and cheese for his breakfast, and very little pocket-money to pay his expenses. But he had gone only a short distance when he overtook a man of grave and sedate appearance, who was trudging at a moderate pace along the road. | 190 | 7 | 3 | -2.141945 | 0.526452 | 55.4 | 13.56 | 15 | 11 | 7.36 | 0.12516 | 0.10116 | 16.862254 | 3,150 |

In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. This pressure difference results in a net upwards force on the object. The magnitude of that force exerted is proportional to that pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the volume of the object, i.e. the displaced fluid.
For this reason, an object whose density is greater than that of the fluid in which it is submerged tends to sink. | 156 | 8 | 2 | -1.238432 | 0.476088 | 61.75 | 10.22 | 10.78 | 11 | 10.08 | 0.3461 | 0.3676 | 15.14524 | 402 |

From the very beginning of the Austrian conflict we strove and worked toward the end that this trouble remain confined to Austria-Hungary and Serbia. All Cabinets, especially that of England, take the same stand; only Russia declares that she must have a word in the decision of this conflict. Therewith the danger of European entanglements arises. As soon as the first authentic reports of the military preparations in Russia reached us we declared in a friendly but emphatic manner in St. Petersburg that war measures and military preparations would force us also to prepare, and that mobilization is closely akin to war.
Russia asserts in what is an apparently friendly manner that she is not mobilizing against us. In the meantime England tries to mediate between Vienna and St. Petersburg, in which she is warmly supported by us.
On July 28 the Kaiser telegraphed the Czar, asking him to consider that Austria-Hungary has the right and that it is her duty to defend herself against Serbian intrigues, which threaten to undermine her existence. | 182 | 8 | 4 | -2.479528 | 0.517425 | 43.77 | 12.96 | 13.44 | 14 | 9.86 | 0.23844 | 0.23844 | 8.851872 | 2,075 |

The Leap-frog said nothing; but people gave it as their opinion, that he therefore thought the more; and when the housedog snuffed at him with his nose, he confessed the Leap-frog was of good family. The old councillor, who had had three orders given him to make him hold his tongue, asserted that the Leap-frog was a prophet; for that one could see on his back, if there would be a severe or mild winter, and that was what one could not see even on the back of the man who writes the almanac.
"I say nothing, it is true," exclaimed the King; "but I have my own opinion, notwithstanding."
Now the trial was to take place. The Flea jumped so high that nobody could see where he went to; so they all asserted he had not jumped at all; and that was dishonorable.
The Grasshopper jumped only half as high; but he leaped into the King's face, who said that was ill-mannered. | 184 | 7 | 5 | -0.846828 | 0.487327 | 73.64 | 8.95 | 9.94 | 10 | 6.55 | 0.08854 | 0.08983 | 16.798099 | 3,609 |
