[Clinicopathology of Epstein-Barr virus-related gastric carcinoma]. | Since Epstein-Barr virus(EBV) was detected in poorly differentiated adenocarcinoma with intense lymphocytic infiltration of stomach, the relationship between EBV infection and gastric carcinoma has been attracted. EBV-related gastric carcinoma is demonstrated by EBV-encoded small RNA in situ hybridization, monoclonality of EBV DNA and elevated antibodies. EBV-related gastric carcinoma is characterized by male predominance, preferential location in the upper and middle part of the stomach, and high prevalence in gastric remnant cancer. Although EBV-positive cases are observed for all histological types and early carcinoma through advanced carcinoma, there is relatively high levels for moderately differentiated tubular adenocarcinoma and solid-type, poorly differentiated adenocarcinoma. EBV-positive early gastric carcinoma shows unique morphology recognized as "lace pattern," and infiltration of CD8-positive cytotoxic T lymphocytes. |
Rapid sizing method for airplanes | A method for rapidly determining airplane takeoff weight, empty weight, and mission fuel weight for a given mission specification is presented. The method applies to a wide range of airplane types and relies on statistical relations between empty weight and takeoff weight of production airplanes. The method can also be used to predict the sensitivity of takeoff weight with respect to changes in the mission specifications as well as to changes in airplane lift-to-drag ratio, specific fuel consumption, and/or propeller efficiency. |
Bayesian Estimation for the Parameter of Exponentiated-Weibull Distribution under Type-II Doubly Censored Scheme | In this paper we discuss the Bayesian estimation for the scale parameter of two parameter EW distribution,based on type-Ⅱ doubly censored sample.Various Bayesian estimates have been derived used non-informative prior and conjugate prior considering squared error loss and LINEX error loss.At last,we compare the accuracy of estimators by means of(Monte-Carlo) simulation. |
Astronomy. Pull of gravity reveals unseen galaxy cluster. | ASTRONOMYAstronomers have discovered a whole new cluster of galaxies and calculated its distance, without relying on its emitted light. Instead they inferred the unseen cluster's existence from the way its gravity rerouted light from more-distant galaxies beyond. The work is the first to show that the technique, known as gravitational lensing, can be used to map matter in deep space. |
Perfect Codes and Uniformly Packed Codes | In this chapter we shall restrict ourselves to binary codes. To obtain insight into the methods and theorems of this part of coding theory this suffices. Nearly everything can be done (with a little more work) for arbitrary fields Fq. In the course of time many ways of studying perfect codes and related problems have been developed. The algebraic approach which will be discussed in the next section is perhaps the most elegant one. We start with a completely different method. We shall give an extremely elementary proof of a strong necessary condition for the existence of a binary perfect e-error-correcting code. The theorem was first proved by S. P. Lloyd (1957) (indeed for q = 2) using analytic methods. Since then it has been generalized by many authors (cf. [44]) but it is still referred to as Lloyd’s theorem. The proof in this section is due to D. M. Cvetkovic and J. H. van Lint (1977; cf. [17]). |
Changes in Chemical/Biological Weapons Technology and Public Opinion since World War II | With the impetus provided by the capture of German nerve agent production plants and agent stockpiles, CW technology moved forward rapidly in the early years after World War II. Both the Soviet Union and the West experimented with these new agents and went on to develop improved variants of their own. |
Electro-optic holography fringe control using diode laser current modulation | Electro-optic holography (EOH) is a whole field, laser-based, vibration measurement technique. Highly dense, unresolvable fringe patterns often limit the EOH measurement range. This paper presents a technique for increasing the measurement range of an EOH system using diode laser current modulation. This technique is known as frequency translated electro-optic holography (FTEOH). Using diode laser current modulation, the fringe patterns are based on higher-order Bessel functions and the sensitivity of the EOH system can either be increased or decreased. The amount of sensitivity reduction is limited only by the frequency limit of the signal generator that modulates the current supplied to the diode laser. EOH and FTEOH experimental results are presented and shown to closely compare. |
PROCEDURE OF RECOVERY, CANCELLATION, MODIFICATION, COMPLETION OR RECTIFICATION OF CIVIL STATUS DOCUMENTS | According to the law, marital status proves to the acts drawn up in the registers of civil status (original acts of civil status), as well as with the civil status certificates issued on the basis thereof. Civil status documents provide proof to the finding of false by a final judgment for other entries, until proof to the contrary, issue, cancellation, rectification or completion or reconstruction of civil status acts, as well as any registrations made on the civil status acts, pursuant to a final and irrevocable judgment or under an administrative provision may be relied on by any person until proof to the contrary. We have proposed in this paper to present the procedure by which acts of civil status can be reconstituted, canceled, corrected, amended and supplemented in order to proof civil status. |

Irregular Ventricular Tachycardia as a Mechanism of Stabilization of Mechanoelectrical Processes in Canine Heart under Conditions of Antiorthostatic Hypokinesia | We studied electrophysiological mechanisms of ventricular arrhythmias in dogs (n=7) under conditions of antiorthostatic hypokinesia (head-down tilt 45°). Abnormal transmural heterogeneity of repolarization in the base and apex of the left ventricle and increased dispersion of myocardial repolarization were revealed. By minute 30 of antiorthostatic hypokinesia, an increase in the duration of repolarization was revealed after a period of ventricular arrhythmia in all segments and regions of heart ventricles, which was accompanied by impairment of the pumping function of the heart. A hypothesis on the physiological role of ventricular tachycardia as a mechanism of electromechanical homeostatic stabilization in the heart was proposed. The obtained results suggest that under conditions of antiorthostatic hypokinesia, canine heart after a paroxysm of irregular ventricular tachycardia becomes more resistant to arrhythmia. |

Risk factors: Sleep apnoea, atrial fibrillation, and heart failure—quo vadis? | Strong associations exist between sleep disordered breathing (SDB) and both atrial fibrillation (AF) and heart failure (HF). Burgeoning epidemics of obesity, SDB, AF, and HF make these conditions priorities for health-care policymakers. Two observational studies now suggest outcome benefits from screening and treating for SDB in AF and HF. |
Capacity market in Poland — Evalutaion of the proposed solution | The first part of the article presents the assumptions of the capacity market in Poland that was recently presented by the Ministry of Economy. The mechanism is based on the centralized capacity market solution already implemented in Great Britain, however, introduces novel solutions such as separate auctions for new and existing power units. In the second part, we described the modifications that could be made in order to specifically address the problems of Polish power sector. The proposed changes are more likely to trigger new investments in the ecological and flexible power units located in the areas that support transmission system. |
Peyronie’s Disease and Other Anatomical Disorders | Disorders of penile anatomy comprise a variety of presentations that produce physical and psychological deficits in men. While congenital disorders like chordee and hypospadias contribute, the acquired condition Peyronie’s disease is by far the most commonly seen penile anatomical disorder. This chapter provides a contemporary review of the pathophysiology, diagnosis, and management of these conditions. |
[Polyneuropathy syndrome in a case of spinal meningeal carcinomatosis]. | The authors report a case of polyneuropathy of lower extremities developing in carcinomatosis of spinal meninges in a patient after gastrectomy for mucus-producing carcinoma. |
Interaction of brain spectrin (fodrin) with phospholipids. | Binding of brain spectrin to frozen and thawed liposomes was studied, using a pelleting assay, as a function of lipid composition. Saturable binding was observed for all lipid mixtures that included aminophospholipids, as well as for the total lipid of synaptic plasma membranes. Binding was strong and saturable, with dissociation constants in the nanomolar range. There were two pH optima at ca. 6.0 and 7.5 and a sharp ionic strength optimum, corresponding to physiological solvent conditions. No competition could be detected with extraneous globular proteins, serum albumin, and hemoglobin. The results imply a strong, direct interaction between brain spectrin and the neuronal plasma membrane in the cell. |

HCl) are described. Topical application of cream and gel formulation of 1 . HCl showed high efficacy against guinea pig dermatophytosis. |
Computational and experimental investigations of supramolecular assemblies of p-sulfonatocalix[4]arene organized by weak forces. | We report the study of the supramolecular assemblies formed by the incorporation of quaternary ammonium cations such as Me4N+ or Et4N+ into host-guest assemblies with p-sulfonatocalix[4]arene in the presence of a lanthanide(III) cation in water. We use microcalorimetry to characterize the formation of these supramolecular assemblies. We obtain a molecular description of these assemblies by performing molecular dynamics simulations over a very large period of time. The structures of these supramolecular complexes have been determined and discussed through specific interaction energy contributions. By combining MD simulations and 1NMR spectroscopy, we highlight a specific behavior of the supramolecular assembly with the Me4N+. |
Fabrication of Porous Structure of BCP Sintered Bodies Using Microwave Assisted Synthesized HAp Nano Powder | Using microwave synthesized HAp nano powder and polymethyl methacrylate (PMMA) as a pore-forming agent, the porous biphasic calcium phosphate (BCP) ceramics were fabricated depending on the sintering temperature. The synthesized HAp powders was about 70-90 nm in diameter. In the porous sintered bodies, the pores having 150-180 μm were homogeneously dispersed in the BCP matrix. Some amounts of pores interconnected due the necking of PMMA powders which will increase the osteoconductivity and ingrowth of bone-tissues while using as a bone substrate. As the sintering temperature increased, the relative density increased and showed the maximum value of 79.6%. From the SBF experiment, the maximum resorption of Ca2+ ion was observed in the sample sintered at 1000°C. |
Selective Cell Control by Surface Structuring for Orthopedic Applications | In this work we present an in vitro study of the influence of two types of femtosecond laser generated topographies on a titanium surface — grooves with different periodicities and “lotus-like” structures — on the behavior of human fibroblast and MG-63 osteoblast cells. We show that anisotropy in wetting of groove structures correlates well with contact guidance of cells. The “lotus-like” structured titanium surfaces show superhydrophobic properties and influence differentially osteoblast and fibroblast adhesion and growth. The proliferation of fibroblast cells is inhibited, whereas the proliferation of osteoblast cells is promoted. This technique for cell specific control offers promising perspectives in fabrication of new functionalized implants. |
Total and free cortisol levels during 1 μg, 25 μg, and 250 μg cosyntropin stimulation tests compared to insulin tolerance test: results of a randomized, prospective, pilot study | Purpose ::: The appropriate cosyntropin dose during cosyntropin stimulation tests remains uncertain. We conducted a prospective, randomized pilot study to compare 1 μg IV low dose cosyntropin test, 25 μg IM medium dose cosyntropin test, and 250 μg IM standard dose cosyntropin test to evaluate secondary adrenal insufficiency. Insulin tolerance test was used as the gold standard. |
An incremental method to detect communities in dynamic evolving social networks | Abstract Detecting communities in dynamic evolving networks is of great interest. It has received tremendous attention from researchers. One promising solution is to update communities incrementally taking the historical information into consideration. However, most of the existing methods are only suitable for the case of one node adding or one edge adding. Factually, new data are always generated continuously with subgraphs joining simultaneously in dynamic evolving networks. To address the above problem, we present an incremental method to detect communities by handling subgraphs. We first make a comprehensive analysis and propose four types of incremental elements. Then we propose different updating strategies. Finally, we present the algorithms to detect communities incrementally in dynamic evolving networks. The experimental results on real-world data sets indicate that the proposed method is effective and has superior performance compared with several widely used methods. |
The efficiency and walking speed of visually impaired people | All pedestrians have a walking speed which they prefer. This appears to be the speed which, for them, is the most physically efficient. Blind pedestrians, if allowed to set the pace when accompanied by a sighted guide, will prefer to walk at a speed which is close to that of sighted pedestrians. However, when walking independently they adopt a pace which is slower than their preferred walking speed. By converting adopted walking speed into a proportion of preferred walking speed we are able to show that subject data may be pooled and comparisons made which had hitherto been impossible. Furthermore, statements may be made about the physiological efficiency of a performance. For example, efficiency varies with route difficulty, increases with increased preview, and only users of guide dogs reach their optimum efficiency. |
Quantitative Effect of N,P and K Fertilizer on Dichondre repens Southern Blight Caused by Sclerotium rolfsii | The effects of nitrogenous,phosphate and potassium fertilizer on Dichondre repens southern blight were different. The results showed that effect of N fertilizer was no significant; P fertilizer had negative correlation to disease under trial condition,which inhibited the occurrence of disease,and K fertilizer had significant positive correlation to disease,which enhanced the occurrence of disease. |

New laytime and demurrage considerations under sale contracts | The recent case of Profindo Pte Ltd v Abani Trading Pte Ltd [2013] SGHC 10 (Comm) seems to have found, and filled, a gap in the law on sale contract demurrage clauses, and is worth exploring. Where laytime is interrupted during unloading, absent fault from either party, how is demurrage to be calculated between buyer and seller? Is laytime to be suspended during unloading or otherwise? It is worth noting that the parties were in agreement that the variances between cif and cfr contracts were immaterial for the purposes of the appeal |
Defining a Noncarcinogenic Dose of Recombinant Human Parathyroid Hormone 1–84 in a 2-Year Study in Fischer 344 Rats | The carcinogenic potential of human parathyroid hormone 1–84 (PTH) was assessed by daily subcutaneous injection (0, 10, 50, 150 μg/kg/day) for 2 years in Fischer 344 rats. Histopathological analyses were conducted on the standard set of soft tissues, tissues with macroscopic abnormalities, selected bones, and bones with abnormalities identified radiographically. All PTH doses caused widespread osteosclerosis and significant, dose-dependent increases in femoral and vertebral bone mineral content and density. In the mid- and high-dose groups, proliferative changes in bone increased with dose. Osteosarcoma was the most common change, followed by focal osteoblast hyperplasia, osteoblastoma, osteoma and skeletal fibrosarcoma. The incidence of bone neoplasms was comparable in control and low-dose groups providing a noncarcinogenic dose for PTH of 10 μg/kg/day at a systemic exposure to PTH that is 4.6-fold higher than for a 100 μg dose in humans. The ability of PTH to interact with and balance the effects of bot... |

Roadblocks to Warrior Subspecialty Development. | This research investigated the factors that influence U.S. Navy unrestricted line (URL) officers' decisions whether to obtain a proven subspecialty in a secondary, technical occupation or not. Data were collected from a sample of 1,329 aviators and surface warfare officers with 10 or more years of commissioned service. Survey data were obtained before the officers had an opportunity to acquire a proven subspecialty and were supplemented from personnel records. Decisions about obtaining a proven subspecialty were most heavily influenced by the officers' perceptions of its contribution to their Navy and post-Navy careers (p < .01). Obtaining a proven subspecialty was influenced by officers' decisions (p < .01) and the opportunity provided by the Navy. It appears to be important for the Navy to ensure that officers with Navy-sponsored educations are provided consistently with opportunities to obtain a proven subspecialty. |
Combining RBF neural network and chaotic map to construct hash function | How to design an efficient and security keyed hash function is always the point in modern cryptography researches. In this paper, A better chaos sequence is generated by RBF neural network through training the known chaotic sequence generated by a piecewise nonlinear map, then the sequence is used to construct keyed hash function. One advantage of the algorithm is that the hidden-mapping model of neural network makes it difficult to get the direct mapping function of the ordinary chaos hash algorithm. Simulation results show that the keyed hash function based on the neural network has good one-way, weak collision, better security property and it can be realized easily. |
Synthesis and Biological Activities of Some Novel Triazolothiadiazines and Schiff Bases Derived from 1,2,4-Triazole | 3-substituted-4-amino-5-mercapto-1,2,4-triazoles are versatile compounds for constructing various biologically active heterocycles. To find more 1,2,4-triazole derivatives that may possess significant biological activities, we synthesized a number of novel 3-(4-ethoxyphenyl)-6-aryl-1,2,4-triazolo[3,4-b][1,3,4]thiadiazines and 4-(arylmethylidene)amino-5-(4-ethoxyphenyl)-3-mercapto-4H-1,2,4-triazoles. All the title compounds were characterized by elemental analysis and NMR data, and the compound 5f was investigated with X-ray crystallography (CCDC No. 611639). The plant-growth regulating effects of those Schiff bases were examined, and they showed an inhibiting effect on the growth of wheat radicles and radish radicles. |
Influence of polycarboxylic-type admixture on the strength of autoclaved aerated concrete | The influence of polycarboxylic-type admixture on the strength of autoclaved aerated concrete (AAC) was investigated. The flexural strength and compressive strength of AAC with polycarboxylic admixture (PA) were tested. The microstructure of AAC reinforced by PA was analyzed using scanning electron microscopic (SEM) methods. The crystal structure analysis of AAC with PA was also carried out using X-ray diffraction (XRD). The results showed that the compressive strength and flexural strength of AAC were increased by 43.9% and 42.8%, respectively, when 1.5wt% of PA was mixed. In addition, the dosage of admixture influenced the reinforcing effect. Admixture affected pore structure and surface characteristic of the products in autoclaved curing process and improved the formation of high crystallite tobermorite which led to the enhancement of the compressive and flexural strength of AAC. |
TRACE EXPANSIONS FOR ELLIPTIC CONE OPERATORS I | Let (M, g) be a Riemannian manifold and E → M a Hermitian vector bundle. Let ::: ::: $$A : {C}_{c}^{\infty }(M;E) \rightarrow {C}^{\infty }(M;E)$$ ::: ::: (1) ::: ::: be a differential operator (with smooth coefficients). |
Geotechnical properties of sediment subjected to ultrasound | The paper reports the comparison of the results of laboratory tests conducted on reconstituted samples of high-plasticity lagoon sediment before and after ultrasonic treatment. The purpose of the work was to evaluate the effects of ultrasonic treatment on the compressibility and velocity of sedimentation and consolidation. The improvement of these geotechnical characteristics may lead to the storage of a greater volume of dredged material in the confined disposal facilities. Tests in a sedimentation column were performed in salt water to investigate the influence of ultrasonic treatment on the occurrence of two different sedimentation processes: zone settling and compression settling. The zone settling velocity of sediment subject to ultrasonic treatment was six times slower than that of natural soils and a significant variation of grain size of the particles was noted. The mechanical effect of sonication produced a reduction in coarse particles, with enrichment of the silty fraction. Different methods of... |
Commercial Credit and Bank Credit:Substitute or Complement? | It is generally accepted that commercial credit can relieve the financing constraint plight faced by enterprises and provide substitution scheme for the enterprises' financing. Using the panel data of Chinese listed companies over the period from 1999 to 2009,this paper studies the relationship between enterprises' commercial credit and bank credit. The study indicates that although there is a substitution relationship between commercial credit and bank credit,the effect depends on the term structure of bank credit and enterprises' position in supply chain. Those enterprises that have more internal funds available,higher liquidity ratio and higher financial cost tend to use less commercial credit. But those enterprises that have higher tangible asset ratio and inventory ratio tend to use more commercial credit. The classification research finds that the substitution relationship between commercial credit and bank credit is stronger for younger and larger enterprises. |
The impact of managed care on physicians' personal finances. | Ultimately, all financial decisions need to take into consideration both the short run implications and the four stages of your professional life. Anyone who attempts to advise or offer you financial products or services without understanding this is doing you a grave disservice. As a physician, your financial needs and concerns are unique, and you will be ill served by a "general investment practitioner" who does not work primarily or perhaps exclusively with physicians. |
[How I study anomalies of glucose metabolism, insulin secretion and the insulin sensitivity with an oral glucose tolerance test]. | Oral glucose tolerance test (OGTT) has been widely used for the diagnosis of diabetes mellitus, gestational diabetes, impaired glucose tolerance or reactive hypoglycaemia. Simultaneous measurements of plasma glucose and insulin levels also allow to derive indices of insulin secretion and insulin sensitivity. Whereas OGTT is not considered anymore as the first choice for the diagnosis of diabetes mellitus, it remains useful for studying abnormalities of glucose metabolism as well as of insulin secretion and insulin action. |
On the Development Dimension of the Human Resources in Guangxi Beibu Gulf Economic Zone | The development of human resources has played an important role in enhancing the competitiveness of regional economic development.The development of Guangxi Beibu Gulf Economic Zone is inseparable from the intelligence support of the regional human resources.The paper,working out a measurement index system of human resources development dimension,tries to evaluate the level of human resources in quantity development,quality development,structure development,and flow development in Guangxi Beibu Gulf Economic Zone,to discover the problems existing in the regional human resources development,so as to provide important scientific basis in hope of realizing the regional strategic target. |
Enantioselective synthesis on the solid phase. | Organic transformations on substrates which are immobilized on an insoluble, polymeric carrier have found broad application in compound collection synthesis. In contrast to other synthetic methodologies in solid-phase organic synthesis, reactions that afford non-racemic products are strikingly under-represented. Not only does the introduction of stereoinformation on immobilized, achiral starting materials provide enantioenriched products which can be of value for biological testing, but it also opens up new perspectives for accessible structures. This feature article gives an overview of successful enantioselective transformations on a solid support. Critical differences in the corresponding solution-phase protocols are highlighted, and applications to the generation of compound collections are particularly mentioned. |
Physisorption of H2 on Fullerenes and the Solvation of C60 by Hydrogen Clusters at Finite Temperature: A Theoretical Assessment | The interaction between hydrogen and carbonaceous nanostructures is of fundamental interest in various areas of physical chemistry. In this contribution we have revisited the physisorption of hydrogen molecules and H2 clusters on fullerenes, following a first-principles approach in which the interaction is quantitatively evaluated for the C20 system using high-level electronic structure methods. Relative to coupled cluster data at the level of single, double, and perturbative triple excitations taken as a benchmark, the results for rotationally averaged physisorbed H2 show a good performance of MP2 variants and symmetry-adapted perturbation theory, but significant deviations and basis set convergence issues are found for dispersion-corrected density functional theory. These electronic structure data are fitted to produce effective coarse-grained potentials for use in larger systems such as C60–H2. Using path-integral molecular dynamics, the potentials are also applied to parahydrogen clusters solvated aro... |
Fluorescence quenching method for determination of trace zinc with salicyl fluorone-Tween-80-hydroxypropyl-β-cyclodextrin | A novel determination method of trace zinc by fluorescence quenching method was established in the presence of hydroxypropyl-β-cyclodextrin(HP-β-CD) and Tween-80 in NaAc-HAc buffer solution and with salicyl fluorone(SAF) as fluorescence reagent.The effects of buffer solution pH and dosage,SAF dosage,surfactant and the addition order of reagents on determination system were investigated,and the optimal experimental conditions were obtained.The results showed that Zn2+ content in the range of 0.036-4.0 μg/25 mL showed good linearity with fluorescence quenching value(ΔF) at maximum emission wavelength(λem=532 nm) of complex(the maximum excitation wavelength was λex= 370 nm).Detection limit of this method was 1.42 μg/L.The proposed method had been applied to the determination of zinc in tap network water.The results were consistent with those obtained by other methods,and the relative standard deviation(RSD,n=5) was 0.42 %. |
[Molecular aspects of the mechanism of anti-oxidant activity of vitamin E: features of the action of alpha- and gamma-tocopherol]. | Current data on mechanisms of vitamin E action are reviewed with the specific reference to the antioxidant theory. Experimental data relevant to this theory on alpha- and gamma-tocopherols reactions in biological and nonbiological systems are considered. Distinctly lower biological activity of gamma-tocopherol, as compared with that of alpha-tocopherol, was shown not to depend only on dissimilar antiradical properties of these two homologues. Tocopherol-binding proteins, exhibiting high affinity only to alpha-tocopherol, appear to be responsible for realization of the biologically important reactions. |
KEKERASAN PADA ANAK DALAM GROUP HOME DI JEPANG YANG TERCERMIN DALAM DRAMA ‘ASHITA, MAMA GA INAI’ | There is child care institutions in Japan called group home. In this group home, child are nurture, care, and protected by creating a peaceful and comfortable environment. The number of children who are cared in group home are less than 10 people. In this group home, the children are not always find happiness. They also can get violent. This research discusses about the acts of violence committed by caregivers to children in a group home in Japan. In addition, authors also discussed about the acts of violence that occur among children in a group home. In this research, the authors used a Japanese drama titled 'Ashita, Mama ga Inai'. The methode used is qualitative method, since this research is descriptive research. To analyze the problem, author uses the theory of semiotics belong to Pierce. Analytical results from this study indicate that the violence perpetrated by caregivers to children are physical abuse and emotional abuse. While violence among children is fighting. |
Hypocalcemia Following Magnesium Sulfate Therapy | To the Editor.— Monif and Savory (219:1469, 1972) reported the case of maternal hypocalcemia secondary to magnesium sulfate therapy for eclampsia, as an example for the interrelationship of magnesium and calcium ions in man. Such an interrelationship is known to exist, though the exact role of parathormone in magnesium homeostasis remains to be defined. 1 Knowledge of the mechanism involved would have considerable implications regarding possible benefits and hazards of therapeutic use of magnesium. We had the opportunity to study the changes of magnesium, calcium, and phosphate in serum and urine after a two-hour intravenous infusion of 41.1 mEq of magnesium (as magnesium sulfate in 200 ml normal saline solution) in 22 normal volunteers, 9 male and 13 female, whose ages ranged from 17 to 61 years. Blood and urine specimens were obtained before infusion, at the end of infusion, and at one-hour intervals, for a total time of four |
[Antibiotics: interactions with other drugs (author's transl)]. | More and more numerous each year, and only rarely beneficial, these are responsible for unexplained therapeutic failures or complications. They may occur at different levels. In the bottle of infusion fluid, the risk is that of neutralisation of varying amounts of the antibiotic. At the physiological stages of pharmacokinetics, there may be reduction of absorption and modification of urinary excretion. The most striking iatrogenic consequences result either from competition for binding to plasma albumins or from induction (or inhibition) of hepatic enzymes responsible for biotransformation (toxic overdose). Within bacteria, these interactions explain synergisms and antagonisms. They should lead to awareness of the multiple dangers of polypharmacy. |
Simulation of Chaos in Different Models of Josephson Junctions | Chaotic behaviors of Josephson junctions are of great value in research and applications. According to Josephson junction dynamics, we put forward the chaotic behavior simulation of different models of Josephson junctions. Then a new method for the research of Josephson junction chaos is presented. There are three kinds of simulation models of Josephson junctions, RCSJ model driven by rf current, RCSJ model with tunnel effect and RCLSJ model. Taking advantage of the models, chaotic properties of Josephson junctions are simulated, including the time-domain properties, frequency-domain properties and the sensitivity to initial conditions. The results prove the models are correct and applied in the chaos research easily. Also the results give the difference of chaotic behavior between the RCSJ model and the RCSJ model with tunnel effect. |

Synthesis of Bis(Benzene)Tetracarbonyldivanadium, (C6H6)2V2(CO)4 | Abstract The synthesis and reactions of (C6H6)2V2(CO)4 are reported showing the presence of a vanadium-vanadium triple bond (V≡V). Preliminary structural data on a twinned crystal indicate a V-V bond length of ∼ 2.25 A. |
Capturing Design Space From a User Perspective : The Repertory Grid Technique Revisited | The design of an artifact (e.g., software system, household appliance) requires a multitude of decisions. In the course of narrowing down the design process, "good ideas" have to be divided from "bad ideas." To accomplish this, user perceptions and evaluations are of great value. The individual way people perceive and evaluate a set of prototypes designed in parallel may shed light on their general needs and concerns. The Repertory Grid Technique (RGT) is a method of elucidating the so-called personal constructs (e.g., friendly-hostile, bad-good, playful-expert-like) people employ when confronted with other individuals, events, or artifacts. We assume that the personal constructs (and the underlying topics) generated as a reaction to a set of artifacts mark the artifacts' design space from a user's perspective and that this information may be helpful in separating valuable ideas from the not so valuable. This article explores the practical value of the RGT in gathering design-relevant information about th... |
Backward design and cross-functional design management | This study establishes a framework for backward design analyses and cross-functional performance management system to achieve product design for excellence. The authors define backward design as opposed to regular forward design. A cross-functional viewpoint emphasizing downstream knowledge and lessons learned is introduced for proactive product design management. The study proposes several approaches for backward design endeavors, including Extended Failure Mode and Effect Analysis (EFMEA), Attributes Function Deployment (AFD), Feedback Tracking and Analysis System (FeTAS), Fuzzy Decision Tree, etc. Based on the backward design concerns, a cross-functional design management system is then established to serve as an incentive system for designer to incorporate cross-functional concerns. The contributions include: (1) Proposing backward design mechanisms; (2) Establishing a cross-functional design management system which is conducive to design for excellence. |

The Impact of CYP2D6 Genotyping on Tamoxifen Treatment | Tamoxifen remains a cornerstone of treatment for patients with oestrogen-receptor-positive breast cancer. Tamoxifen efficacy depends on the biotransformation, predominantly via the cytochrome P450 2D6 (CYP2D6) isoform, to the active metabolite endoxifen. Both genetic and environmental (drug-induced) factors may alter CYP2D6 enzyme activity directly affecting the concentrations of active tamoxifen metabolites. Several studies suggest that germline genetic variants in CYP2D6 influence the clinical outcomes of patients treated with adjuvant tamoxifen. Here, we review the existing data relating CYP2D6 genotypes to tamoxifen efficacy. |
[Anatomo-clinical study of a case of regenerative nodular hyperplasia of the liver with Felty's syndrome and portal hypertension]. | Regencrative nodular hyperplasia (RHN) is a rare condition, the diagnosis of which is based upon histological findings. It is seen in Felty's syndrome with portal hypertension (PHT), as was the case in the patient reported here. This was a 72-year-old man, with long standing rheumatoid arthritis, hepatosplenomegaly, a neutrophil leucopaenia and oesophageal varices responsible for recurrent haematemeses. Despite a portocaval anastomosis, the patient died from postoperative acute hepatic failure. Histological study revealed changes in the hepatocytes and the reticulin system typical of RNH without cirrhosis. The relationship between Felty's syndrome and RHN, as well as the mechanism of the hypertension, are discussed in the light of cases from the literature. |
Gold nanoparticle-coated silicon cone array for surface-enhanced Raman spectroscopy | ABSTRACTWe demonstrate a silicon cone array substrate coated with gold nanoparticles and which was highly sensitive, homogeneous, and provided a large area for surface-enhanced Raman spectroscopy (SERS). A deep reactive ion-etching process was used to fabricate the high-density silicon cone array, and gold nanoparticles were formed on the silicon cone surface by magnetron sputtering. The substrate was tested with 10−6 M rhodamine 6 G solution. Enhancement of the substrate was about 60-fold greater than that of flat substrate. Moreover, SERS signals obtained from 24 random areas on the substrate showed good homogeneity with an average standard deviation of 3.9%. |

Vibration reduction of cable-stayed bridge model retrofitted with SMA restrainers | Shape Memory Alloys (SMAs) are more and more frequently used in civil structures subjected to extreme dynamic loadings. Due to their unique properties, the SMAs are used for seismic retrofit of bridges, tall buildings and masts. The paper presents selected results of numerical calculations of a cable-stayed steel bridge model retrofitted with SMA restrainers. The original set of constitutive relationships describing pseudoelastic properties of SMA was used for this purpose. The formulation of SMA model is based on analysis of a special rheological scheme representing its constitutive properties. The SMA model was implemented within FEM software Abaqus using an user defined subroutine. It was proved that the application of SMA restrainers can reduce significantly vibrations and internal forces caused by seismic excitations. |
Fundamental studies of new high-energy permanent magnet materials | Rare-earth transition metal nitrides and carbides have been prepared by gas-solid reaction with N and HC gases. Neutron diffraction was used to study changes in structure which accompany the nitridation. In NdFe[sub 10]Mo[sub 2]N[sub x], nitrogen occupies the base center site (1/2, 1/2, 0) of the tetragonal unit cell with 84% occupancy. Two crystal structure types were found in LaFe[sub 13[minus]x]Si[sub x]; nitridation of the cubic phase expanded the unit cell by 6.2-10.8%, leading to increases in Curie temperature and spontaneous magnetization. The interstitial N atom from nitridation expanded the unit cell volume of NdFe[sub 10]Mo[sub 2] by 3%; the Curie temperature reached 563 K. Magnetically hard NdFeMoN[sub x] with coercivity 8.8 kOe at RT and 33.7 kOe at 10 K were obtained by nitriding melt-spun ribbons. |
The ac susceptibility of Y2Cu2O5 | Abstract The temperature dependence of the real and imaginary part of the ac susceptibility was measured for polycrystalline Y 2 Cu 2 O 5 . It was found that apart from the known maximum at 13 K, connected with the antiferromagnetic transition of Cu ions, another maximum appears at about 5.8 K. It is very weak and disappears almost completely for an external magnetic field of above 100 Oe. |
Experimental Results of a Raspberry Pi Based WMN Testbed for Multiple Flows and Distributed Concurrent Processing | Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers, because of their potential use in several fields such as collaborative computing and communications. Considering mobility of the terminals, routing is a key process for operation of WMNs. In this paper, we present the implementation of a testbed for WMNs. We analyze the performance of Optimized Link State Routing (OLSR) protocol and parallel distributed processing in an indoor scenario. For evaluation we considered hop count, delay, jitter and processing time metrics. The experimental results show that the nodes in the testbed were communicating smoothly. The processing time for node 1 is smaller than other nodes. |
Delamination problems of UV-cured adhesive bonded optical fiber in V-groove for photonic packaging | In this letter, we investigated the origin of the interfacial delamination due to uneven curing of ultraviolet (UV) adhesive in the fixing process of a fiber on a V-groove. The analytical ray tracing technique is used to estimate the UV intensity at different locations along the adhesive-fiber interface. Consequently, the unexposed or shaded region in the adhesive layer is determined, through which the interfacial delamination as a result of the reliability test is predicted. |
2-Diazomethyl-4-furanones. Synthesis and properties | 1,5-Bisdiazo-3-alkylpentane-2,4-diones were synthesized by the reaction of alkylmalonic acid chlorides with diazomethane; the products readily undergo intramolecular cyclization at the oxygen atom and one of the diazoacetyl groups under the influence of acidic agents with the formation of 2-diazomethyl-3-alkyl-4-furanones. It is shown that diazomethyl-4-furanones, which are vinylogs of α-diazo ketones, undergo reactions that are characteristic for aliphatic diazo compounds. The structure of the product of 1,3-dipolar cycloaddition of dimethyl acetylenedicarboxylate to a diazomethyl-4-furanone was investigated by means of x-ray diffraction analysis. |
Method for producing thermal-transfer-image-receiving sheet support, and method for producing thermal-transfer-image-receiving sheet | Provided is a method for producing a thermal-transfer-image-receiving sheet support with which it is possible to obtain a thermal-transfer-image-receiving sheet that has high uniformity of properties and is easily handled, air bubble formation in an adhesive layer of the thermal-transfer-image-receiving sheet being prevented, while maintaining glossiness. A resin 15 is supplied to one surface of a base material 1 and passed between a cooling roller A(12) and a rubber roller A(13); and a porous film 4 is superimposed on the other surface of the base material 1 with a resin 15 interposed therebetween, the porous film 4 being passed between a cooling roller B(22) and a rubber roller B(23). The ten-point average roughness (Rz) of the surface of the cooling roller A(12) is 5-30 μm, the ten-point average roughness (Rz) of the surface of the cooling roller B(22) is 0-20 μm, the rubber hardness (durometer (type A)) of the rubber roller A(13) is 60-95, and the rubber hardness of the rubber roller B(23) is 50-80. |
Width and layout dependence of HC and PBTI induced degradation in HKMG nMOS transistors | This paper discusses in detail the effects of transistor width and layout on the Hot-Carrier (HC) and Positive Bias Temperature Instability (PBTI) induced degradation in nMOS transistors fabricated using a 28-nm gate-first HKMG CMOS technology. It is observed that the HC and PBTI induced degradation reduces with reduction in the width of HKMG nMOS transistors. The physical mechanisms behind this width dependence are attributed to reduction in the number of defect states in HfO2 for narrow width transistors. It is also shown that the long term reliability of the HKMG nMOS transistors could be further improved by dividing a single active into multiple actives, by increasing the active-to-active spacing and gate pitch. |
Reflections on the Use of Technology in the Mathematics Classroom. | ABSTRACT The use of technology in collegiate mathematics classrooms is increasing. The most effective means of using technology, however, is an open question. During the summer of 1993, the Department of Mathematical Sciences at Montana State University offered an experimental course in which the programming language ISETL served as a tool for exploring concepts in abstract algebra. This paper describes these efforts and offers informal observations regarding the effectiveness of this approach. In addition, the paper identifies instructional strategies that (in the opinion of the author) facilitate the successful use of ISETL in abstract algebra. These strategies are offered as a preliminary model of technology use in the mathematics classroom. |
Full-Wave Analysis of Dielectric Waveguides at a Given Frequency | New variational formulation to compute propagation constants is proposed. Based on it. vector finite element method is proved to exclude spurious modes provided finite elements possess discrete compactness property. Convergence analysis is conducted in the framework of collectively compact operators. Reported theoretical results apply to a wide class of vector finite elements including two families of Nedelec and their generalization, the hp-edge elements. Numerical experiments fully support theoretical estimates for convergence rates. |
Basic principles and advantages of the | Electrostatic projection methods are now well established as a primary means of corrosion protection and product finishing. Until about 18 months ago these methods were used almost exclusively for depositing paint surfaces, but they are now rapidly establishing themselves as techniques for plastics coating and vitreous enamelling. Compared with the conventional, compressed‐air‐spraying technique, the electrostatic method sometimes exhibits quite remarkable advantages, best known of which is the almost complete elimination of overspray. This arises from the ‘homing’ charge given to the atomised paint during the spraying operation. |
William James’s Pragmatism. Ethics and The Individualism of Others | In his popular lecture “On a Certain Blindness in Human Beings” (1899), William James considers the lack of awareness that we often have toward the insights of other people. “There is no point of view absolutely public and universal,” he says, and “even prisons and sick-rooms have their special revelations.” While every observer “gains a partial superiority of insight from the peculiar position in which he stands,” the stubborn fact, according to James, is that “neither the whole of truth nor... |

This mini review briefly summarizes topical use of selected most common medicinal herbs, naturopathic chemicals, and bioactive peptides examined for skin protection. |
X-ray micro-diffraction studies of heterogeneous interfaces between cementitious materials and geological formations | In the present study the challenge of analyzing complex micro X-ray diffraction (microXRD) patterns from cement–clay interfaces has been addressed. In order to extract the maximum information concerning both the spatial distribution and the crystal structure type associated with each of the many diffracting grains in heterogeneous, polycrystalline samples, an approach has been developed in which microXRD was applied to thin sections which were rotated in the X-ray beam. The data analysis, performed on microXRD patterns collected from a filled vein of a cement–clay interface from the natural analogue in Maqarin (Jordan), and a sample from a two-year-old altered interface between cement and argillaceous rock, demonstrate the potential of this method. |
Synthesis and swelling behavior of temperature responsive κ-carrageenan nanogels | Abstract Crosslinked κ-carrageenan hydrogel nanoparticles (nanogels) with an average size smaller than 100 nm were prepared using reverse microemulsions combined with thermally induced gelation. The size of the nanogels varied with biopolymer concentration at a constant water/surfactant concentration ratio. The nanogels were found to be thermo-sensitive in a temperature range acceptable for living cells (37–45 °C) undergoing reversible volume transitions in response to thermal stimuli. This opens the possibility to explore the application of these nanogels in smart therapeutics such as thermo-sensitive drug carriers. As such, the sustained release of methylene blue from the nanogels was evaluated in in vitro conditions as proof of concept experiments and the release rate was found to be controlled with temperature. |

Association and Feeding Relationships Between Eogammarus confervicolus (Amphipoda, Gammaridae) and Benthic Algae on Sturgeon and Roberts Banks, Fraser River Estuary | Field and laboratory studies of the feeding and association of the gammarid amphipod Eogammarus confervicolus with algae and vascular plant debris were conducted on jetties, marshes, and sandflats at the Fraser River Estuary. Associations with Prasiola meridionalis (alga), and debris from Carex lyngbyei (vascular plant) were statistically significant. Vascular plant debris was more widespread in winter (January) compared to a summer survey (August). Laboratory growth rates and survival varied with food types, which were ranked (best to worst) as follows: Enteromorpha linza, Pylaiella littoralis, Porphyra spp., Navicula grevillei, Carex lyngbyei debris and Ulva lactuca. Assimilation efficiencies, measured with gravimetric and radioisotope techniques (14C) ranged from about 78% with P. littoralis to 62% with U. lactuca. Construction of jetties could increase the surface area for algal growth, but there would be no appreciable enhancement of primary production compared to a natural marsh/sandflat ecosystem.K... |
Geometrically invariant image watermarking in the DWT domain | Watermark resistance to both geometric attacks and lossy compressions is a fundamental issue in the image watermarking community. In this paper, we propose a DWT (Discrete Wavelet Transform) based watermarking scheme for such a challenging problem. Watermark resistance to geometric deformations is achieved by using the invariance of the histogram shape. In both theoretical analysis and experimental way, we show that the invariance can be extended to the DWT domain thanks to the time-frequency localization property of DWT. Consequently, we achieve the goal to embed a geometrically invariant watermark into the low-frequency sub-band of DWT in such a way that the watermark is not only invariant to various geometric transforms, but also robust to common image processing operations. Extensive simulation results demonstrate the superiority of the proposed watermark strategy due to the use of the histogram shape invariance combined with the DWT technique. |

Enabling Automated Transparency for the Market Participation of ESCOs with Blockchain | This study investigates the decision problem that Energy Service Companies (ESCOs) encounter for growing their project portfolios whilst seeking financial investors. Global investment in energy efficiency expanded in 2016 at 9%, despite low energy prices, with most of those investments in buildings, which account for one-third of total energy demand. Nevertheless new ways for raising equity and debt, are needed to enable developers to access into larger financing pools, especially for funding retrofitting assets and small-scale energy efficiency projects. We provide an analysis of portfolio generation using digital data system architectures implemented with Blockchain technology as transaction mechanism. |
Physiopathology and diagnosis of nephrogenic diabetes insipidus | Nephrogenic diabetes insipidus (NDI) is caused by an improper response of the kidney to the antidiuretic hormone arginine vasopressin (AVP), leading to a decreased ability to concentrate urine which results in polyuria and polydipsia. The clinical diagnosis of NDI relies on demonstration of subnormal ability to concentrate urine despite the presence of AVP. NDI is most commonly acquired, secondary to kidney disorders, electrolyte imbalance and various drugs. Congenital forms of NDI are rare, and most commonly inherited in a X-linked manner with mutations of the AVP receptor type 2 (AVPR2). Mutations of the water channel aquaporin-2 (AQP2) can be detected in autosomal recessive or dominant forms of NDI. Management of NDI should focus on free access to drinking water and reduction of polyuria. |

Design of composite filters with equiripple passbands and least-squares stopbands | We study a class of composite filters (C-filters), each is composed of a prototype filter and a shaping filter in cascade, where the shaping filter is constructed by cascading several complementary comb filters. In particular, the problem of designing a C-filter with equiripple passband and least-squares stopband subject to peak stopband gain is formulated and an algorithm for designing such a class of linear-phase FIR C-filters is proposed. The algorithm is based on an alternating convex optimization strategy in that the prototype and shaping filters are optimized in separate steps which are coupled and carried out in a sequential manner to yield a satisfactory design. Design example is presented to illustrate the algorithm and demonstrate the performance of the C-filter relative to its conventional FIR counterparts. |

[Features of the innervation of fascia and their microcirculatory bed in the rat]. | By means of silver impregnation, methylene blue staining and using glyoxylic acid, the neural apparatus of the muscle fasciae in the shoulder girdle and back and their microcirculatory bed have been revealed in laboratory white rats. An uneven concentration of neuronal terminals makes the base of neurotissue interactions of the muscle fasciae of the shoulder girdle and the back of the rats. Only a small part of microvessels possesses neural elements. The fasciae and their microvessels are innervated both by sensitive and sympathetic neural fibers and their endings; they differ from each other morphologically and histochemically. The rat fasciae are useful objects for vital observations for behaviour both of the vascular nerves and the avascular areas. |
Symbol of Good or Ill Luck and Their Cultural Sources in English and Chinese Numerical Words | The worship and taboo of numerical words is the important content of numerical culture.As numerical words carry rich cultural information,different numbers have different symbolic sense in English and Chinese.Studying the background knowledge of their cultural sources in the two languages help to know cultural differences,eliminate cultural conflict and improve people's inter-cultural communication. |
Experimental study and numerical modelling of thermo-mechanical behaviour of Tournemire argillite | In this paper, we present an experimental investigation and a numerical modelling of thermo-mechanical behaviour of Tournemire argillite. In the first part, the results of triaxial compression tests under two different temperatures are presented in order to show the thermal effect on the mechanical behaviour. In the second part, taking into account the induced thermal effects on shear strength at critical state, a new thermo-elasto-plastic model is proposed for Tournemire argillite. An internal variable is introduced in this model for the purpose of describing thermal effect on elasto-plastic properties. In addition, the post-peak behaviour is considered as a plastic strain softening in the model. |
NITROGEN FIXATION IN POLLUTED SEAWATER OF ALEXANDRIA COAST, EGYPT. | The inshore area of the Mediterranean water, west of Alexandria, Egypt, is subjected to different types of pollutants. Nitrogen fixation rate was studied in this area in relation to some environmental factors such as pH, oxygen, organic matter, total and inorganic phosphorus and ammonia. In addition, numbers of Cyanobacteria, as nitrogen fixers, were also determined. In order to identify possible relationships between environmental conditions and N-fixation, correlation coefficients were determined for each environmental factor and rates ofN-incorporation. Temporal and spatial variations were observed in the rate of nitrogen fixation, related to a number of factors. Positive correlations were found between the rate of N-fixation and organic matter, total and inorganic phosphorus and the densities of Cyanobacteria in the region. On the other hand, N-fixation was negatively correlated with both ammonia and oxygen concentration. |
Troubled Past of 'Invisible' Profession | ABSTRACT NURSING in the United States is a paradox.It is the most populous profession in health care, with 2.1 million registered nurses alone; yet it has undergone repeated cycles of shortage and oversupply, with shortage the current order of the day. The development of trained nurses helped make possible the rise of both the modern hospital and modern medicine, yet nursing has been a relatively powerless part of health care.Ninety-seven percent of nurses are female and 91% are non-Hispanic whites, yet nursing has been divided internally from the beginning. Often its members have spent more time fighting each other than any outside enemy.And although it is critical to most patient care, nursing's profile is quite low. In the summer 1987 issue of Inquiry, Claire Fagin, PhD, dean of the University of Pennsylvania School of Nursing, Philadelphia, wrote: "As patient needs become greater, requiring more and better-educated nurses, the |

Joint Audit through Law and Sociology | This paper uses Carbonnier’s sociology of law as a theoretical framework to understand the efficiency of joint audit in the French corporate governance context. Joint audit has been strongly criticized by a range of professionals, academics, and politicians. These criticisms focus on the ineffectiveness of the law underpinning joint audit. We show that these criticisms are based on a confusion between material and symbolic effectiveness of the law and are unable to undermine the relevance of joint audit which remains a key institution of corporate governance. |
[Latissimus dorsi flap in reconstructive surgery of the lower limbs]. | The free latissimus dorsi flap has been used to repair 10 complex losses of substance of the lower extremity. The results have shown the great reconstructive potentialities of the microvascular transfer of this muscle, considered by the authors the most versatile of the myocutaneous flaps. Among the advantages there are the extended surface, its thickness, its pedicle with adequate length and diameter as well as the absence of functional involvement, especially by preserving the upper branch of the thoracodorsal nerve. The indications, however, are limited due to a significant rate of complications which prevent its extended use. |
Theory of mode-locked semiconductor lasers | We present a theoretical study of semiconductor mode-locked lasers at a phenomenological level. We use the slow absorber model of New and Haus, but extend the analysis by taking into account the shift in the gain maximum due to the changing number of carriers. In our analysis of the resulting equation, we show that due to stability requirements the shortest attainable pulse duration is limited. The use of self-phase modulation due to a slow medium can at most lead to a shortening of the pulse by a factor of 2. We show that the shifting of the gain maximum due to the changing number of carriers in the laser is a crucial aspect in the operation of mode-locked semiconductor lasers. We further find that the end mirrors must be reflecting more than about half of the light intensity to prevent a self-pulsation type instability similar to the relaxation oscillation. |
Recent results of fracture experiments on carbon steel welded pipes | Abstract Several pipe fracture experiments were conducted with circumferential cracks in the center of ferritic nuclear pipe welds. These experiments involved either submerged arc or shielded metal arc welds with either through-wall cracks or internal surface cracks. The pipe diameters varied from 940 mm (37 inches) to 152 mm (6 inches), and thickness from 10·9 mm (0·43 inches) to 86·6 mm (3·41 inches). Some of the through-wall and surface-cracked pipe experiments were conducted under constant internal pressure and four-point bending. The test temperature was 288°C (550°F). The results of these experiments are compared with limit-load analyses, the ASME, Section XI, article IWB-3650 criterion, and more elaborate elastic-plastic fracture mechanical analysis. |
Effective site finding using link anchor information | Link-based ranking methods have been described in the literature and applied in commercial Web search engines. However, according to recent TREC experiments, they are no better than traditional content-based methods. We conduct a different type of experiment, in which the task is to find the main entry point of a specific Web site. In our experiments, ranking based on link anchor text is twice as effective as ranking based on document content, even though both methods used the same BM25 formula. We obtained these results using two sets of 100 queries on a 18.5 million document set and another set of 100 on a 0.4 million document set. This site finding effectiveness begins to explain why many search engines have adopted link methods. It also opens a rich new area for effectiveness improvement, where traditional methods fail. |
Zinc Sulfide Phosphor Constitution and Its Effect on Electron Traps | The phosphorescence and thermoluminescence of zinc sulfide phosphors are governed by the mechanism of electron trapping in the phosphor crystal lattice. Experiments have been carried out to find the effect of phosphor constitution and method of preparation on the numbers and the energy distribution of electron traps. In order to investigate the traps, use has been made of the thermoluminescence vs. temperature characteristics of the phosphors.These experiments show that pure zinc sulfide and zinc sulfide activated by silver and manganese possess similar ``shallow'' electron trap configurations after preparation and that these configurations are not markedly dependent on the particular activator. However, the introduction of copper impurity to zinc sulfide causes a marked change in the number and distribution of electron traps and is responsible for the long afterglow of these phosphors. Investigations of the effect of firing temperature and crystal form on the electron traps show that below the blende‐wur... |
Defining Limits by Means of Integrals | A particular notion of limit is introduced, for Riesz space-valued functions. The definition depends on certain ideals of subsets of the domain. It is shown that, according with our definition, every bounded function with values in a Dedekind complete Riesz space admits limit with respect to any maximal ideal. |
