Liquid crystal televisions are popular low-cost spatial light modulators. One LCTV of interest is found in the InFocus TVT-6000 television projector. A wavefront splitting interferometer has been constructed and analyzed for measuring the complex characteristics of these modulators, including phase and amplitude coupling. The results of this evaluation using the TVT-6000 projector drive electronics have been presented in a previous work. This work will present results of the complex characterizations of these modulators using custom drive electronics.


Objective:To study the efficacy of single itraconazole and combination with interferon-γ against Candida albicans infection.Methods:Murine models of systemic candida albicans infection were established, and treated with different concentrations of itraconazol alone and combination with INF-γ. Then the concentrations of colonyforming units(cfu) and histolo gical sections were observed to evaluate the emcacy. Results:The combination of 105U INF-γ and itraconazole at the dosage of 10mg/kg showed better effect against Candida albicans than the combination of itraconazole at the dosage of 50mg/kg with 105U INF-γ. Conclusion:The combination of itraconazole at a low dose with INF-γ shows a good effect against Candida albicans.The single use of itraconazole at a high dose is also anti-infection.


Meticulous painting in the embarrassing situation in the art history is the result of the monism context of literati painting.Fine brushwork painting is different from painter painting,because the former is the description of the objective aspect rather than the subjective aspect in the pursuit of painting artistic conception.In the pursuit of the imagery vision and poetic attainment,it pays more attention to the painting's strength.What's more,its idea and artistic conception creation are expressed entirely through the accurate and faithful painting language,which is a valuable mode for later generations.


This prospective observational study was designed to assess the incidence of, risk factors for, and outcome of catheter-related bloodstream infection in children undergoing cardiac surgery. A staff specifically trained to handle the central venous catheters with proper aseptic techniques and an appropriate patient to medical staff ratio remain the most effective measures to prevent this infection.


Approximate value iteration is used in dynamic programming when we use random observations to estimate the value of being in a state. These observations are smoothed to approximate the expected value function, leading to the problem of choosing a stepsize (the weight given to the most recent observation). A stepsize of 1/n is a common (and provably convergent) choice. However, we prove that it leads to very slow convergence for a basic instance of approximate value iteration, to the point of being unusable for most applications. We then derive an optimal stepsize rule for that instance. This is the first stepsize rule that explicitly takes into account the covariance between the current observation and the previous prediction in approximate dynamic programming. The rule can be easily extended to general ADP settings; experimental results show that it produces fast convergence without the need for tunable parameters.


William Riker's article explains a central thesis of social choice theory with its author's characteristic vigor. The initial notion, first put forward some 195 years ago in Condorcet's Essai (1785) is this: Given three or more alternatives (say, laws or candidates) and three or more voters, majorities may march in circles even while individuals do not. The contemporary literature presents an essentially two-sided extension of Condorcet's little discovery: (i) that the Condorcet paradox can be avoided only at cost of violating some other reasonable-sounding axioms for social choice (viz., Arrow's theorem), and (ii) that under majority rule itself, cyclic majorities will be common, often large, generally without a single alternative immune to the process of cyclic dominance. This second range of findings, built up by Kramer, Plott, Fishburn, Bell, McKelvey, Schofield, and many others, tells us that the Condorcet paradox is no fluke, and therefore is not the dismissible "phantom" which Gordon Tullock used to make it out to be. It must be integrated with, not banished from, our understanding of political theory. This is what Riker tells us, and I agree. The question is to see why we should care about transitive consistency in liberal democratic (or any other) political theo ry.


It is shown that a wet process for thin Si and Ge films deposition based on the ballistic electron injection into solutions is available for SiGe. A nanocrystalline silicon (nc-Si) diode is composed of a thin Au (10 nm)/Ti (1 nm) film surface electrode, nc-Si layer (~1 µm), n+-Si substrate, and back contact. The electrochemical effect of ballistic hot electrons was confirmed by cyclic voltammetry analyses. Electrons are emitted from the nc-Si device on which a very small amount of SiCl4+GeCl4 solutions is dripped. After the emitter operation, thin SiGe films are deposited on the emitting surface with neither byproducts nor contaminations as in the case of thin Si and Ge films deposition. Based on the structural and compositional characterizations of deposited SiGe films, the specific features of this reduction-induced deposition mode are discussed in comparison with the conventional processes.

In the field of statistical disclosure control, the tradeoff between data confidentiality and data utility is measured by comparing disclosure risk and information loss metrics. Distance based metrics such as the mean absolute error (MAE), mean squared error (MSE), mean variation (IL1), and its scaled alternative (IL1s) are popular information loss measures for numerical microdata. However, the fact that these measures are unbounded makes it is difficult to compare them against disclosure risk measures which are usually bounded between 0 and 1. In this note, we propose rank-based versions of the MAE and MSE metrics that are bounded in the same range as the disclosure risk metrics. We empirically compare the proposed bounded metrics against the distance-based metrics in a series of experiments where the metrics are evaluated over multiple masked datasets, generated by the application of increasing amounts of perturbation (e.g., by adding increasing amounts of noise). Our results show that the proposed bounded metrics produce similar rankings as the traditional ones (as measured by Spearman correlation), suggesting that they are a viable additions to the toolbox of distance-based information loss metrics currently in use in the SDC literature.


At present, in the aviation sector considerable scientific project work deals with the development of fuel cell systems based on synthetic fuels to be integrated in future aircraft. The benefits of fuel cell systems in aircraft are various. They offer the possibility to simplify the aircraft layout. Important systems, i.e. the gas turbine powered auxiliary power unit (APU) for electricity supply, the fuel tank inerting system and the water tank, can be substituted by one single system, the fuel cell system. Additionally, the energy demand for ice protection can be covered assisted by fuel cell systems. These measures reduce the consumption of jet fuel, increase aircraft efficiency and allow the operation at low emissions. Additionally, the costs for aircraft related investments, for aircraft maintenance and operation can be reduced. On the background of regular discussions about environmental concerns (global warming) of kerosene Jet A-1 and its availability, which might be restricted in a few years, the aircraft industry is keen to employ synthetic, sulfur-free fuels such as Fischer-Tropsch fuels. These comprise Bio-To-Liquid and Gas-To-Liquid fuels. Within this field of research the Institute of Energy Research (IEF-3) in Julich develops complete and compact fuel cell systems based on the autothermal reforming of these kinds of fuels in cooperation with industry. This paper reports about this work.


INTRODUCTION The Sport Psychology is being more and more recognized as a sports science (in the theoretical field) and as a useful tool for sports clubs (in the practical field). The human behavior study, Psychology responsibility, is both complex and important. The Sport Psychology was officially recognized by American Psychological Association (APA) as a Psychology specialty in 1986. It studies behaviors and situations in the very specific environment of sport and physical exercise, significantly changing many athletes and sport professionals lives. It is only natural that the psychological aspects are considered essential training components, responsible for important differentials in the high performance sports, mainly when, more and more, the physical, technical and tactical factors are evened among teams and athletes (WEINBERG; GOULD, 2001; SAMULSKI, 2002; DANTAS, 2003; RUBIO, 2004). The professional soccer involves vast financial interests and occupies considerable media space. In Brazilian History, soccer has well-known associations with Sports Psychology since 1958, with João Carvalhaes in São Paulo F.C. and 1962, with Athayde Ribeiro da Silva in the Brazilian National Team that won the country's second World Cup in Chile. More recently, Regina Brandão work alongside Filipe Scolari was noticed when Brazil conquered its fifth World Cup in Japan/Korea 2002. (BRANDÃO, 2000; BECKER JR, 2000, OSTERMANN, 2002). However, as this study carried through in 2004 shows that the Brazilian south region first state soccer division psychologists seem not to be conquering their due space.


A self-sensing magnetic suspension system with an H-bridge hysteresis amplifier is developed. Since the H-bridge drive circuit consists of a pair of transistors and a pair of diodes, the amplifier operates in two quadrants; the output current has one polarity while the polarity of the voltage applied to the coil is reversed alternatively. The switching characteristics of the amplifier are studied both analytically and experimentally. The measurement results show that the switching frequency is proportional to the air gap between the electromagnet and the suspended object, and insensitive to the value of current command. A digital control system is developed in which the displacement of the suspended object is estimated based on the period time measurement of the switching signal. Self-sensing suspension is achieved with the developed hysteresis amplifiers and the digital control system.


With the development of computer technology and communication technology, the demand for broadband smart grid services is rising rapidly, and the network traffic is growing rapidly. With the digital evolution of power grid, smart grid has also emerged, which makes broadband power network more widely used. In recent years, the traffic and bandwidth of smart grid have increased dramatically, smart grid is facing increasing risk of attack, traffic anomaly detection for smart grid is of great significance to the healthy development of broadband smart grid. This paper proposes a traffic anomaly detection method based on hierarchical spatial-temporal feature learning for smart grid service, using Res2Net and Spatial Attention Mechanism to improve CNN to extract spatial features, and then connect Bidirectional LSTM module to extract temporal features. This method extracts features from temporal granularity and spatial granularity. By adding multi-scale feature extraction module and spatial attention module, while obtaining spatial feature information of different scales, different weights are given to spatial features, and more attention is paid to the parts containing more key information, the part that contains less key information will be less concerned, thereby enhancing the ability of feature representation, improving the accuracy of traffic anomaly detection, and reducing the false alarm rate of smart grid.


Pathogenic fungi are associated with diseases ranging from simple dermatosis to life-threatening infections, particularly in immunocompromised patients. During the past two decades, resistance to established antifungal drugs has increased dramatically and has become extremely important to identify novel antimicrobial compounds. The purpose of this study was to synthesize some new benzimidazole derivatives and to evaluate their activity against some species of Candida, Aspergillus and dermatophytes. Benzimidazoles have been synthesized in the presence of nano-TiCl 4 .SiO 2 as a reusable and efficient catalyst. The stability of different tautomers of some products has been investigated using standard ab initio calculations. The antimicrobial activities of the synthetic compounds have been tested against the fungi by Broth microdilution method as recommended by Clinical and Laboratory Standards Institute (CLSI). Inhibition studies showed that some of the tested compounds, in particular 2-(2,3-dihydroxyphenyl)-1H-5-Nitro-benzimidazole exhibited strong antifungal activities against all tested fungi at concentrations of less than 32 µg/mL while some of them only inhibited the growth of dermatophytes or Aspergillus species. These results suggest that the derivatives should be further investigated for possible use in antimicrobial products. Rezumat


Active β-alanine esters having dipeptide groups, which are capable of forming hydrogen bonds between the side chains, were prepared in the form of hydrogen chloride salts. The polycondensation of these salts was studied in non-polar solvents, in the presence of triethylamine. In the case of the ester with β-alanyl-β-alanine as dipeptide moiety, the polycondensation proceeded smoothly in chloroform solution. To explain the characteristic feature of the polycondensation, an ordered aggregation of the ester molecules is assumed to play an important role. The ester with glycylglycine as dipeptide moiety, however, did not undergo a polycondensation.


Parathyroid cysts are uncommon and are often misdiagnosed as lesions of the thyroid gland. There have been 143 cases reported, most of which were diagnosed only at surgery 11 ]. Sonography is now used often in the evaluation of neck masses, and fine-needle aspiration biopsy is playing a larger role in the clinical management of suspected thyroid disease. Therefore, it is likely that more parathyroid cysts will be encountered. The sonographic features are nonspecific, but the characteristics of the aspirated fluid may allow for the prospective nonsurgical diagnosis of parathyroid cyst.


A two-criterion kinetic damage model is proposed to describe the development of the fatigue fracture process under cyclic loading. On this basis, a procedure is proposed for calculating the coefficients of the kinetic equation for various modes of fatigue fracture from low-cycle to very-high-cycle fatigue. A uniform numerical method has been developed based on an implicit approximation of the differential equation for damage. This method makes it possible to carry out an end-to-end calculation of the evolution of crack-like zones of fatigue fracture in the material without considering cracks in their classical sense, as well as to estimate the durability of samples from the first nucleation to macrofracture. Calculations were made of the fatigue fracture of specimens under long-term cyclic loading according to the three-point bending scheme with the development of crack-like fracture zones in the modes from HCF to VHCF. Comparison of numerical and experimental results for specimens of titanium alloys is carried out.

Parsons's training as an economist, his graduate stay at Heidelberg, and his participation in the Henderson seminar at Harvard provide major clues to his familiarity with Marshall, Pareto, and Weber—three of the four figures whose convergence forms the major theoretical achievement in The Structure of Social Action. But what led him to Durkheim, since Parsons did not study or reside in France, yet read Durkheim in the original, remains an enigma. Without resolving the enigma, this paper argues that Parsons had a great deal in common with Durkheim, and, equally important, that in his mature and late periods he found in his "revisits" of the later writings of Durkheim both inspiration and affinity. I argue that Parsons well deserves recognition as a major authority on Durkheim, and that both combined offer an alternative to the contemporary version of utilitarianism.

This paper describes a technique for accurate threedimensional (3D) position estimations by integrating the extended phase accordance method (EPAM) and the particle filter (PF). Unlike existing positioning systems, EPAM can obtain not only the 3D position but also the instantaneous velocity of the target by using ultrasonic transducers installed with a short baseline. PF uses the position and velocity obtained by EPAM to compute more accurate estimations. The experimental results proved that the integration of EPAM and PF could improve the positioning accuracy. When a single compact ultrasonic receiver unit mounting four ultrasonic sensors to form a 76.2 mm square was used, the average 3D position error was improved from 40 mm to 29 mm. The 95th percentile of the error was also improved to 114 mm while that of EPAM without PF was 160 mm.


In this article, the authors provide a diachronic analysis of the urr variable as it appears in African American English (AAE) spoken in St. Louis. While many believe that this linguistic feature is a product of hip-hop, invented recently for creative purposes, the authors provide linguistic evidence that shows it to be a prevalent feature of dialects of AAE spoken in St. Louis, Missouri, and East St. Louis, Illinois, at an earlier time. The authors suggest that the increase in vowel centralization that evolved in St. Louis is similar to that found in Memphis, Tennessee, along an s-curve pattern. Finally, the authors theorize about how the use of the urr variable by hip-hop artists correlates with its increased usage in present-day local communities. They employ notions of indexicality, meaning making, acts of identity, and accommodation to argue for linguistic convergence between St. Louis rappers and local communities. They argue that the increased usage and acceptance of vowel centralization in local communities is supported by hip-hop language as opposed to innovated through it.

The present invention relates to a receiver for providing a reduced signal interference, receiver circuitry and methods. A receiver is configured to receive a received signal comprising a plurality of signal components, each signal component indicative of antenna ports scrambling sequence and an associated channel, wherein said signal components by a first scrambling sequence based on a first signal components indicated by the first one of the channels is allocated to the receiver for receiving data, and based on a second scrambling different from the first sequence of the signal components second scrambling sequence indicated by the signal component of the channel interference of the second channel being allocated a channel. The receiver includes an interference reduction unit, the interference of the reducing unit is configured to combine the signal components of said first signal component estimate and the second signal component in signal component estimates to provide a reduced signal interference.


The heterogeneously-catalysed oxidation of hydrocarbons over oxide catalysts is reviewed. The first section of the paper deals in a general way with the structural features of hydrocarbons and relates these to the selective oxidation products which may be obtained from them. The interaction of oxygen and hydrocarbons with oxides is also considered in a general context and the kinetics of heterogeneous oxidation of hydrocarbons are discussed. The second section of the paper deals in more detail with the selective oxidation of aromatic hydrocarbons with particular reference to vanadium oxide containing catalysts. Finally, an account is given of the selective oxidation of monoalkenes to 1,3 conjugated systems and ketones over mixed oxide catalysts. The information available is considered throughout with a view to revealing those features of such systems which give rise to the selectivity.


The seismological aspects of various proposed means of obscuring or hiding the seismic signatures of explosions from a surveillance network are discussed. These so-called evasion schemes are discussed from the points of view of both the evader and the monitor. The analysis is conducted in terms of the USSR since that country is so vast and its geological and geophysical complexities are so great that the complete spectrum of hypothesized evasion schemes requires discussion. This part of the paper (Part I) is a general discussion of the evasion schemes, placing the concepts within the reality of general factors influencing effective use of the techniques. Part III will describe techniques appropriate for use when the noise problem is the P and surface-wave codas of earthquakes, and will give analyses of capabilities of several seismological networks to restrain use of such codas for effective evasion.


We report a novel PbS/Er co-doped silica fiber (PEDF) with improved spectral properties in O-band (1260–1360 nm). The results show that the gain of the PEDF exceeds 15 dB in the range of 1150–1360 nm. Compared to PbS-doped silica fiber, the PEDF has a gain improvement of 6.4–10.9 dB in O-band. In addition, the concentration of Pb and S in the PEDF core is significantly higher, and the size distribution of PbS nanoparticles is more concentrated in a narrow range. These factors may account for the enhanced gain characteristics of the PEDF. This work reveals the positive effect of co-doping Er3+ ions on the gain characteristics of the PEDF in O-band, and suggests an important research direction for the design of broadband amplifiers and light sources for optical communication with zero dispersion.


In this paper, we investigate the concepts of downward continuity and upward continuity. A real valued function on a subset E of R, the set of real numbers, is downward continuous if it preserves downward quasi-Cauchy sequences; and is upward continuous if it preserves upward quasi-Cauchy sequences, where a sequence (xk) of points in R is called downward quasi-Cauchy if for every ε > 0 there exists an n0 ∈N such that xn+1 − xn < ε for n ≥ n0, and called upward quasi-Cauchy if for every ε > 0 there exists an n1 ∈ N such that xn − xn+1 < ε for n ≥ n1. We investigate the notions of downward compactness and upward compactness and prove that downward compactness coincides with above boundedness. It turns out that not only the set of downward continuous functions, but also the set of upward continuous functions is a proper subset of the set of continuous functions.


The studies on spermatogenesis and spermiogenesis of teleost in recent years are reviewed in the present paper. It is pointed out that the characteristics of spermatogenesis and spermiogenesis can be used to study phylogenetic devlopment of teleost,and that the comparative study of spem ultrastructure and the three\|dimensional structure of big molecules on the sperm\'s surface of different species has a broad prospective application in the study on evolutionary biology of teleost


ZnSe/semi-insulating GaAs interfaces were studied by observing photogenerated plasmon–LO (PPL) coupled modes by nonresonant micro-Raman spectroscopy. The effect of the carriers generated by the focused laser beam was investigated for a series of different thicknesses of ZnSe epitaxial layers. The PPL mode in GaAs was observed in the micro-Raman spectra for all samples, but with different magnitude. The plasma is believed to be an electron gas as a result of the negative nature of the interfacial region that contains predominantly hole traps. The free carrier concentration is estimated to be > 1018 cm−3 and their lifetime ∼0.1 ns. This relatively long lifetime suggests that the ZnSe/GaAs interface has to be of high structural quality leading to a low recombination velocity. ZnSe/GaAs heterostructures of less crystalline quality (as determined by resonant Raman measurements) shows the effect of photogenerated carriers only to lesser extent.

It is undeniable that we cannot live without water. Safe and clean water supply is crucial to human life activities. It is estimated that 80 per cent of all diseases and more than a third of death in this world is caused by using contaminated water. Constant effort that started in the 1980s has brought water services and sanitation to hundreds of millions of the poor population of the world. Among the efforts are the launch of Sanitation Century and International Drinking Water supply in 1981 resulting in the Mar del Plata Action Plan used by the United Nations. But do we know that to produce clean drinking water, chemicals and electricity are needed? Life cycle assessment (LCA) has found that the chemicals and electricity generation in the drinking water production has the potential of releasing green house gases such as carbon dioxide, methane, carbon monoxide and dinitrogen monoxide. Thus raising the dilemma between basic necessity and the issue of saving the world from the impact of climate change. The use of LCA as a tool to achieve sustainable development could detect weaknesses in any system studied. Analysis has shown that the electricity generation using natural gas fuel emits the highest green house gases such as carbon dioxide (95.26%) and methane (4.47%) while PAC contributes the lowest. This situation should be solved by using electricity generated from alternative sources such as photovoltaic and hydroelectric that emits less green house gases.


The separation of low pour point fractions from Yu-Men light lubricating oil cut by the method of adsorption using silica gel,aluminum oxide,active clay and active carbon as adsor- bents,and by the method of thermal diffusion was investigated. Adsorption on silica gel,aluminum Oxide and active clay,only a small portion with lower pour point was obtained,while the pour points of larger portions are higher than that of the original stocks.It was found that active carbon,especially the Fushun active carbon is very effective for the separation of low pour point lubricating oil,the quantity of fractions with pour point below -35℃(the pour point of the original stock)separated is 40%,a lowest pour point fraction of -63℃ can be obtained. Thermal diffusion method is also effective for the separation of low pour point lubricating oil,but the lowest pour point of the fraction recovered is found to be -55℃,


We consider the problem of estimating the number of common complements of a family of subspaces over a finite field, in terms of the cardinality of the family and its intersection structure. We derive upper and lower bounds for this number, along with their asymptotic versions as the field size tends to infinity. We use these bounds to describe the general behavior of common complements with respect to sparsity and density, showing that the decisive property is whether or not the number of spaces to be complemented is negligible with respect to the field size. The proof techniques are based on the study of isolated vertices in certain bipartite graphs. By specializing our results to matrix spaces, we answer an open question in coding theory, proving that MRD codes in the rank metric are sparse for all parameter sets as the field grows, with only very few exceptions. We also investigate the density of MRD codes as their column length tends to infinity, obtaining a new asymptotic bound. Using properties of the Euler function from number theory, we then show that our bound improves on known results for most parameter sets. We conclude the paper by establishing two structural properties of the density function of rank-metric codes.

A new approach to designing bilateral power transaction bargaining models between two independent utilities in a deregulated electricity market is proposed. In the paper it is assumed that each utility (a seller or a buyer) knows its own operating costs but does not know those of its opponent. The bilateral power transaction problem is then considered as nonco-operative bargaining under incomplete information. Each participant develops its own bargaining strategy based on estimates of the opponent's operating costs and bargaining strategy. Two bargaining models are developed and examples are employed for demonstration.


This is a critical qualitative study grounded in the tripartite frame of Black masculinity, critical race theory and career development theory. The study revealed that African American professional men experience repressive and facilitative structures due to gendered racism, which impacts their careers in ways that are different from their White male counterparts and African American professional women. The study adds to the small body of literature in adult education on career development and race and responds to the call for more culturally relevant career development. Background United States companies (corporate America) are far more diverse today than at any other time in the nation's history. African American professionals' participation in corporate America, like the participation of other professionals of color and women, increased tremendously as a result of the civil rights movement and ensuing legislation. By 2050, African Americans are projected to make up 14 percent of the U.S. workforce, albeit due largely to the growth of African American women's participation (Toossi, 2006). Even with increased access and representation, African Americans continue to encounter racism and disparate treatment, which impedes their career development (Barrett, Cervero, & Johnson-Bailey, 2004; Greenhaus, Parasuraman, & Wormley, 1990; James, 2000; Thomas & Gabarro, 1999). African American men appear to be especially vulnerable, but their experiences are not well delineated in career development literature. When researchers have focused on African Americans, they have tended to treat African Americans as a monolithic group or delve more specifically into how the intersection of race and gender impacts the career development of African American women. Many of the issues facing African American men are different from those faced by African American women (Bingham & Ward, 2001). The universal approach to understanding African Americans' career development experiences is problematic because it has rendered invisible the range of experiences germane to African American professional men in corporate America. African American professional men's career development deserves attention for three reasons. First, the numbers indicate they are in trouble. Not only do they lag behind their White counterparts in workforce participation, promotions and pay, they also trail African American women in many of the same measures with one exception – median earnings. Second, African American men encounter gendered racism, meaning they are subjects of prejudice, negative stereotypes and oppression because they are both Black and men – "blackmen" – a multidimensional understanding of their single social position (Mutua, 2006, p. 18). They experience covert gendered racism in the hiring process. As "soft skills" – defined broadly as interaction skills and motivation skills – have become increasingly more important to employers, these elusive criteria have proven detrimental to African American men in gaining access to jobs


Kevin Kumashiro's book, Against Common Sense , is a book that all educators who care about interrupting norms, challenging oppressions, and questioning the way things are always done, shoud read. It is an accessible book for teachers on the front lines and is filled with practical suggestions for many different subjects. The book also offers a critique for faculties of education to consider, one which challenges the way anti-oppressive teaching is often an afterthought, not a priority, in teacher-preparation, based on the author's research of many US Universities. Ultimately, the book is a call for educators to challenge easy, common sense, solutions; it is a call to action.


Down syndrome is the fourth most come syndrome caused by chromosomal abnormalities. This syndrome includes many abnormalities such as thyroid hormone disfunction. The current study was designed to determine the prevalence of thyroid dysfunction in clinically diagnosed cases of Down syndrome patients that were confirmed on karyotyping later before including in the study. This Cross-sectional study was carried out at different Hospitals of Lahore to find out the prevalence of thyroid hormone dysfunction in 50 clinically diagnosed Down syndrome (DS) subjects from September 2019 to May 2021 by measuring thyroid function test (T3, T4, TSH), and antithyroid antibodies (ATA). A total 50 Down syndrome cases were included in the study and found majority of the patients were males 33(66.0%) while 17(34.0%) were female. Thyroid dysfunction was found in 27 (54%) of DS subjects, of whom 13 (26.0%) had hypothyroidism, 08 (16.0%) were having subclinical hypothyroidism, 01 (2.0%) had sick thyroid syndrome, 4 (8.0%) were hyperthyroidism and 01 (2.0%) were subclinical hyperthyroidism. ATA was positive in 07 (14.0%) patients of DS, of whom 02 (28%) were male and 05 were female (72%), 03 had hypothyroidism, 02 had hyperthyroidism, 02 had subclinical hypothyroidism. remaining 23 (46.0%) were having euthyroid status. This study showed 54% of down syndrome patients that were clinically diagnosed had thyroid hormone dysfunction. It can be concluded that thyroid hormone dysfunction in found in high prevalence in DS patients.


satirist," delivers a painfully honest speech that seems to express Zoshchenko's own fears about the frailties of human character; this passage concludes: "Stormy applause. All rise." Scatton remarks in her own parentheses, "This is one of those infuriatingly ambiguous moments in Zoshchenko's writing. Does the tacking on of these pro forma responses to political speechmaking cast doubt on the sincerity of the monologue which preceded them?" Of course it does. It is precisely by casting doubt—on the most heartfelt "truths," on the most wrenching honesty—that great satirists work their magic.

With rapid construction of hydropower stations and deep underground projects under high water pressure,there are more and more seepage failure risks in these projects. As a result,the in-situ high pressure permeability must be tested and the high pressure permeability properties and seepage stability of rock masses must be systematically and thoroughly studied. In this work,according to the revealed phenomenon in field and the water-rock interactions,the seepage failure mechanisms and failure modes of fractured rock masses under high water pressure are discussed. In addition,based on high pressure packer tests or high pressure permeability tests of several hydropower sataions under high water head,the permeability properties such as hydraulic fracturing, seepage deformation,erosion resistance and long-term seepage stability are studied. The results indicate that:(1) The permeability properties of fractured rock masses can be remarkably changed by high water pressure.(2) The changes of permeability properties are quite correlative with water pressure,supporting environment of stress and fracture fillings.

The finite model calculated results are in good agreement with the results of previous papers of Pseudo dynamic test. It is concluded that this containment vessel has sufficient aseismic safety. It can provide a reference for seismic design.


The radical cations of DNA constituents generated by the ionizing radiation initiate an alteration of the bases, which is one of the main types of cytotoxic DNA lesions. These cation radical spices are known for their role in producing nucleic acid strand break. In this study, the gas-phase intrinsic chemical properties of the gaseous radical cations of cytosine and its base pair with guanine were examined by employing density functional theory (B3LYP) with the 6-311++G(d,p) basis set. Structures, geometries, adiabatic ionization energies, adiabatic electron affinities, charge distributions, molecular orbital analysis and proton-transfer process of these molecules were investigated. The influence of cation radical formation on acidities of multiple sites in cytosine molecule was investigated. Results of calculations revealed that cytosine radicals formed by deprotonation of cytosine cation radicals can exothermically abstract hydrogen atoms from thiol groups, phenol, and α-positions of amino acid. Furthermore, comparison of acidity value of N–H sites of cytosine cation radical with the known proton affinities (PA) of organic and biological molecules implied that cytosine cation radical can exothermically transfer onto basic sites of amino acids and peptides.

Abstract A deep approach to learning is essential for student academic achievement and several studies demonstrate a significant association between such an approach to learning and student academic performance. However, findings from some empirical studies in this domain are inconsistent and the main objective of this study was to determine the feasibility of application of the Biggs (2001) Revised Two-Factor Study Process Questionnaire (R-SPQ-2F) for the diagnosis and monitoring of teacherstudent approaches to learning. Also, the aim of this study was to examine the association of the different approaches to learning with student reading habits and literacy skills. The sample included 202 undergraduate teacher education students. The study found that both, male and female students at the year of study have similar deep and surface approaches to learning. This initial evaluation of the R-SPQ-2F indicates that the questionnaire has acceptable internal consistency and is a promising short instrument for the diagnosis of student teachers′ deep and surface approaches to learning. Results are discussed with reference to a procedure that combines qualitative and quantitative data to increase the diagnostic validity of student learning approaches. Based on the findings of this study, it seems that the R-SPQ-2F scale can be used as a reliable instrument that can help educators diagnose and encourage the development of student teacher approaches to learning, that is a significant contributing factor to their academic performance and teaching practice.


For over a decade, velocimetry based techniques have been used to infer the electrical current delivered to dynamic materials properties experiments on pulsed power drivers such as the Z Machine. Though originally developed for planar load geometries, in recent years inferring the current delivered to cylindrical coaxial loads has become a valuable diagnostic tool for numerous platforms. Previous work summarized uncertainties that can propagate through the current inference technique when applied to cylindrical anodes. The present work compensates for a known source of error generated when openings (slots) are cut into the cylindrical anode to allow optical diagnostic access to the load anode/cathode gap.

A cobalt−rhodium mixed-metal carbonyl complex Co2Rh2(CO)12 effects efficient catalytic silylformylation of an alkyne that adds silyl and formyl groups across the C−C triple bond. A bimetallic synergism in this reaction was elucidated with density functional calculations. The catalytic cycle consists of oxidative addition of hydrosilane, alkyne insertion, CO insertion, and reductive elimination. While major bond-forming events take place only at the rhodium center, the cobalt also plays an important role; it fixes the metal cluster on the organic substrate, keeps the hydride ligand temporarily on the metal center, and suppresses hydrosilylation, which would otherwise be preferred over the silylformylation. The Rh and Co atoms exchange electrons with each other, giving rise to a unique bimetallic reaction pathway that is related to but different from the conventional pathways of hydroformylation and hydrosilylation.


Cortical resections in epilepsy surgery tend to involve multiple lobes in children, compared to adults, partly due to underlying pathology. Oligodendroglia‐like cells (OLCs) have been observed in surgical specimens from children with pharmacoresistant epilepsy. We hypothesize that OLCs recruit multiple‐lobe epileptogenic zones in pediatric pharmacoresistant focal epilepsy.

In this paper, we have study a 3.3kv silicon power diode BDIH with double injection holes on the back side, which structure with an inner N+ layer in the back P region of the CIBH. Based on Sentaurus-TCAD software, we simulate the reverse recovery process of BDIH diodes and conventional PIN diodes when the both diodes work on the condition that real current lower than standard current. The BDIH structure combines the advantages of RFC diodes and CIBH diodes, and the performance of it is better than that of conventional diodes, obviously improving the softness of reverse recovery at small current densities.


Nuclei with a quadrupole deformation such as $^{177}$Hf have enhanced weak quadrupole moment which induces the tensor weak electron-nucleus interaction in atoms and molecules. Corresponding parity non-conserving (PNC) effect is strongly enhanced in the $^3\Delta_1$ electronic state of the $^{177}$HfF$^+$ cation which has very close opposite parity levels mixed by this tensor interaction. In the present paper we perform relativistic many-body calculations of this PNC effect. It is shown that the tensor weak interaction induced by the weak quadrupole moment gives the dominating contribution to the PNC effects in $^{177}$HfF$^+$ which significantly exceeds contributions of the vector anapole moment and the scalar weak charge. The anapole and the weak charge can contribute due to the nonadiabatic mechanism proposed here. Therefore, corresponding experiment will allow one to separate the tensor weak PNC effect from the other PNC effects and to measure the quadrupole moment of the neutron distribution which gives the dominating contribution to the weak quadrupole moment.


The Florida Photovoltaic (PV) Buildings Program will conduct a variety of application experiments over the next decade to gather information that will help define the costs, value and benefits of using photovoltaics with buildings. Four main sources of revenue will support the program: a photovoltaic system buy down (from the present through December 2001), green pricing (present to 2010 and beyond), buy up by end users, and contracts, grants and other subsidies. To give the program sufficient breadth, three different application experiments are planned for each of nine target groups. The data and information from these experiments will help reduce or eliminate key barriers to the commercialization of photovoltaic buildings.


The relation among the woman and the society could make up her mind in some situations. Therefore, these people, through advices, guidance and stress can contribute for the breast-feeding success or failure. In order to plan the actions to promote breast feeding, it is important and essential to know the woman network and the feeding support practice. On this point of view, it was developed on 2012 a study that evaluate the primary and secondary woman network actions considering these relevance on the duration of the breast-feeding. This study has built and validated the measure instruments of woman network support actions, whose psychometric tests were developed on this research. Literature research, developed on the text, show the lack of standardization of devices to measure attitude, experiences and satisfaction of the woman during breast feeding. Thus, this study objective is to analyze the psychometric characteristic of measuring instruments of supportive practices of women, partner and grandmother to breastfeeding. A 45 woman sample with breast feeding experience was interviewed, including al health family teams of sanitary district IV of Recife city. The construto validation was verified thought factorial analysis. Considering the reliability, it was measured the intern consistency using Cronbach alfa and the stability test-retest using the intraclass correlation coefficient. It was observed that the maternal practices scale of support to feed breasting was reliable and valid. The last ten item develop three dimensions (self-assurance, help request, information request) being responsible for 52,39% of the variance. Cronbach alfa of 0,609 and significant intraclass correlation coefficient were obtained. The paternal practices scale of support to breast feeding had 16 last item shared in 6 dimensions, resulting in 68,34% of variance, these scales were: concrete help, nutritional aspect, appreciation, proactive attitude, negative support and brevity. For these aspects it was obtained a good reliability with a 0,831 as Cronbach alfa. For the grandparents' aspects due to feed breasting, ten items shared in two dimensions: concrete help and valorization and incentive, that results in 53,34% of total variance. This scale is also reliable, with a Cronbach alfa of 0,811 if applicable in distinct moments. The three scales validated on this study show good psychometric characteristics and could be used in scientific research and clinics. These scales are valuable device on the support of feed breasting woman considering the mother, the father and the grandmother aspects. The obtained data can be used also as subsidy to plan medical interventions and educational actions in oder to improve the support network on the woman breast feeding.


The disposal of municipal solid waste (MSW) is currently a great challenge to society mainly due to the threat posed by leachate and gases released from the decomposition sites. Landfills have been widely used for this purpose because their waterproofing, drainage and treatment systems have reduced the risks of soil, water and air contamination. Estimating the amount of leachate and gases generated is extremely important for the control and operation of these systems. In this context, this study was developed in the landfill of Timbó, State of Santa Catarina, Brazil, in order to estimate the generation of leachate and to evaluate the effect of profile composition. HYDRUS-1D was used to simulate unsaturated fluid flow through layers. Data on soil matrix such as characteristic curve and unsaturated hydraulic permeability were obtained from previous studies and pedotransfer functions and the respective curves for MSW were obtained from literature. Thirteen layers were simulated by attributing an atmospheric variably boundary condition on top cover and free drainage on the bottom of the profile for two hydrologic years (2017-2019). HYDRUS-1D overestimated the leachate volume by 33.67% when compared with field data. Layers distribution showed an attenuation effect on leachate production which is consistent with design.


. The article deals with a topical issue of organizing self-directed learning for future natural science teachers in the context of educational management. Educational management of students' self-directed learning is defined as a specially organized activity aimed at developing respective skills; a process that involves relevant tools to identify their level of such skills; methods for developing self-directed learning skills while teaching natural sciences; a system of criteria for assessing the level of such skills in future natural science teachers. The article shows that effective educational management of self-directed learning skills in future natural science teachers lies in a gradual expansion of students' subjective functions in the educational process. In turn, this determines the strategy for educational management of students' self-directed learning skills. There are five main types of subject-subject interaction within educational management of self-directed learning skills in higher education institutions. The first type is characterized by the teacher's algorithmic regularization of student activities. The second type is seen as an alternative instruction on rational types and forms of activity, as well as students' right to choose. The third type allows teachers to assign tasks to students and provide instructions for finding possible ways to solve them, always taking into account their level of self-directed learning skills. According to the fourth type, the teacher's role involves setting tasks and, if needed, consulting those students who independently choose the ways of performing them. The fifth type of subject-subject interaction is mostly determined by self-directed learning of students. Finally, the article specifies the stages of developing self-directed learning skills in future natural science teachers. They are as follows: diagnostic (determining an initial level of self-directed learning skills); organizational (setting the aim and tasks of independent work for students in the context of natural sciences, preparing tasks, providing instructions); activity-related (consulting, providing methodological assistance and supervising).

Abstract Technology transforms traditional logistics processes, driving supply chain leaders to adapt. COVID-19 highlighted the importance of public health response logistics and supply chain technologies and the need for employees with new levels of expertise. These supply chain technologies include 3D printing, robotic production, automated inventory management, automated shipping, Blockchain technologies, connected handheld devices, demand forecasting information systems, and digital dashboard tracking information systems. By 2060 women of color will represent (51.7 %) of the workforce, which will lead to significant changes in the composition of workforce hiring pools. As the industry experiences technological knowledge workplace shortages, the need to include more diverse employees, especially African-American women, has never been more necessary. This research explores approaches to make public health response logistics technology organizations more inclusive and psychologically safe for Black women using qualitative interviews to provide data that be used to constructively influence the world of professional practice.


This manuscript presents three families of distributions, namely the Beta, Beta Prime and Beta Exponential families of distributions. From all the distributions of these families, 14 statistical distributions of three, four and five parameters are presented that have applicability in the analysis of extreme phenomena in hydrology. These families of distributions were analyzed regarding the improvement of the existing legislation for the determination of extreme events, specifically the elaboration of a norm regarding frequency analysis in hydrology. To estimate the parameters of the analyzed distributions, the method of ordinary moments and the method of linear moments were used; the latter conforms to the current trend for estimating the parameters of statistical distributions. The main purpose of the manuscript was to identify other distributions from these three families with applicability in flood frequency analysis compared to the distributions already used in the literature from these families, such as the Log–logistic distribution, the Dagum distribution and the Kumaraswamy distribution. The manuscript does not exclude the applicability of other distributions from other families in the frequency analysis of extreme values, especially since these families were also analyzed within the research carried out in the Faculty of Hydrotechnics and presented in other materials. All the necessary elements for their use are presented, including the probability density functions, the complementary cumulative distribution functions, the quantile functions and the exact and approximate relations for estimating parameters. A flood frequency analysis case study was carried out for the Prigor RiverRiver, to numerically present the proposed distributions. The performance of this distributions were evaluated using the relative mean error, the relative absolute error and the L-skewness–L-kurtosis diagram. The best fit distributions are the Kumaraswamy, the Generalized Beta Exponential and the Generalized Beta distributions, which presented a stability related to both the length of the data and the presence of outliers.


The research presents the development of the knowledge value‐adding model (KVAM) for quantitative performance measurement of the community of practice (CoP) of the knowledge management system (KMS) in an A/E consulting firm. The proposed KVAM combines several existing KM theories including knowledge creation spiral, knowledge chain model, and knowledge value added theory to form a process‐level model for measuring the performance of a generic community of practice (CoP). Case study results show that the proposed KVAM provides KM managers with a useful tool not only to monitor the performance of a CoP and its members but also to plan an effective strategy for performance improvement. Unlike the traditional organizational‐level approaches, the proposed KVAM was concluded to better reflect the actual values solely generated by the KMS rather than other management factors.


Protection scheme is desperately needed in the power system network. Protection system plays an important role in detecting the presence disorders and may prevent damage caused interference. This can improve the reliability of the system to maintain continuity of supply to the load. Overcurrent protection is among the important and earliest protection scheme in power system. However the interruptions in power system can happen by fault current. Besides, the improper setting or wrong selection and positioned of the power protection devices is among the reason. Therefore, to maintain and improve the performance of the protection system, this thesis presents a model of overcurrent protection scheme in power system. This thesis describes research carried out to investigate the performance of overcurrent relay on relay operation time (ROT) based on several cases. The model of overcurrent protection system and analysis is developed by using PSCAD simulation software. There are several requirement or conditions are set in order to understand and analyze the reaction and performance of protection system model. The various type and location of faults and relays is proposed in this project to see the changes in power system protection performance. Besides, the implementation of different curve characteristic and various standard also performed. Other than that, installation of distributed generator are also determined because it will give a different impact and result to the power system protection when faults are occur in the system. The result will be studied in order to understand the performance of overcurrent relay in protection scheme.


Recent improvements in object detection have shown potential to aid in tasks where previous solutions were not able to achieve. A particular area is assistive devices for individuals with visual impairment. While state-of-the-art deep neural networks have been shown to achieve superior object detection performance, their high computational and memory requirements make them cost prohibitive for on-device operation. Alternatively, cloud-based operation leads to privacy concerns, both not attractive to potential users. To address these challenges, this study investigates creating an efficient object detection network specifically for OLIV, an AI-powered assistant for object localization for the visually impaired, via micro-architecture design exploration. In particular, we formulate the problem of finding an optimal network micro-architecture as an numerical optimization problem, where we find the set of hyperparameters controlling the MobileNetV2-SSD network micro-architecture that maximizes a modified NetScore objective function for the MSCOCO-OLIV dataset of indoor objects. Experimental results show that such a micro-architecture design exploration strategy leads to a compact deep neural network with a balanced trade-off between accuracy, size, and speed, making it well-suited for enabling on-device computer vision driven assistive devices for the visually impaired.

We present a 43-year-old woman with relapsing–remitting multiple sclerosis (MS) who developed lupus syndrome after 32 months of IFN-β-1a therapy. She presented with malaise, myalgia, arthralgia and fever. Laboratory tests showed high erythrocyte sedimentation rate, anaemia and lymphopenia. Antibodies to double stranded DNA (dsDNA) of IgG, IgM and IgA classes were detected on Critidia luciliae. Additionally, high levels of anti-nucleosomal antibodies, low levels of anti-histone and anti-Ro/SSA antibodies were also found. Diagnosis of drug-induced SLE was established. Treatment with IFN-β was discontinued and oral prednisone was started. Twelve weeks after cessation of IFN-β therapy, the patient's symptoms completely resolved and autoantibodies disappeared. To the best of our knowledge, this is the first report of a patient with MS in whom treatment with IFN-β induced lupus syndrome and antibodies to dsDNA and nucleosome.


Tolerance limits are limits that include a specific proportion of the population at a given confidence level. In the context of process control, they are used to make sure that production will not be outside specifications. It is proposed to obtain long-term and short-term estimates of the process tolerances and to use them in capability analysis as an alternative method to the use of capability ratios. This includes monitoring a tolerance chart to assess continuously process tolerances, similar to a chart of process capability indices. Examples are provided for the continuous assessment of process tolerances and use of estimated tolerance limits as a diagnostic tool in process control.

A new apparatus using the inductance method has been built to test the homogeneity of large area high-T-c superconducting thin films. The apparatus has an X-Y scanning probe that can be moved at liquid nitrogen temperature to test the different regions of the films. The sample chamber of the apparatus can provide large area with high temperature homogeneity. The maximum sample size that can be measured is 50x50 mm(2). A small size of high-T-c superconducting thin film is applied to test the temperature homogeneity of the testing system and the sameness of the gap distance between the surface of the film and probe. A method for testing the apparatus is illustrated, and some experiments for the test of the apparatus have been performed. Experimental results find that the maximum temperature difference is 0.05 K at the surface of the sample mounter, and the drive field remains constant within the error of 5% in the process of X-Y scanning. The apparatus can test the homogeneity of high-T-c superconducting films not only by the superconducting transition temperature T-c, but also by the critical sheet current density K-c.

This study agrees with previous research on the welfare magnetism for immigrants in generous welfare states compared to those with less generous welfare provisions. This study does not stop at just agreeing with the positive previous research of welfare magnetism, this thesis` focus is to present other important factors when dealing with forced immigrants movement choice. In this study case;asylum seekers, not only generous welfare benefits of a country attract forced immigrants, but a combination of immigration policies, networks(social media)and generous welfare provisions attract forced immigrants to a particular country compared to another. This thesis conducted the study by comparing Sweden and Denmark which fall under the same welfare model(Social-democratic) by using secondary sources; mostly recent newspaper articles and government publication statistics. The study concluded that most asylum seekers prefered applying to Sweden compared to Denmark due to their network information, more generous welfare provisions and more welcoming immigration policies in Sweden comparedto Denmark. Despite the fact that, both these countries offer generous welfare provisions compared to other countries in the other two welfare models. (Less)


The determination of the dynamical causes of the morphological Butcher-Oemler (BO) effect, or the rapid transformation of a large population of late-type galaxies to earlier Hubble types in the rich cluster environment between intermediate redshifts and the local universe, has been an important unsolved problem that is central to our understanding of the general problems of galaxy formation and evolution. In this article, we survey the existing proposed mechanisms for cluster galaxy transformation, and discuss their relevance and limitations to the explanation of the morphological BO effect. A new infrared diagnostic approach is devised to disentangle the relative importance of several major physical mechanisms to account for the BO effect, and an example of the first application of this procedure to a single rich intermediate redshift galaxy cluster is given to demonstrate the viability of this approach. The preliminary result of this analysis favors the interaction-enhanced secular evolution process as the major cause of the cluster galaxy morphological transformation. This conclusion is also supported by a wide range of other published results that are assembled here to highlight their implications on a coherent physical origin for the morphological BO effect.

Equilibrium of plasmas in a uniform magnetic field is considered with E × B plasma motion perpendicular to the magnetic field and gravitational field (simulating magnetic field curvature). It is concluded that the equilibrium of moving plasmas in the absence of current parallel to the magnetic field is limited to a very small class of configurations even without the gravitational field. With the motion of plasma included, the plasma equilibrium other than the plasma pressure, p = p(U) where U is the gravitational potential, can be constructed. Finally, the implication of the plasma motion for the increase of the resistive diffusion is considered. It is shown that under a large‐Larmor‐radius configuration, the resistive diffusion could be increased over the classical rate by an amount proportional to the square of the length of a device over the plasma radius.


In recent years, the trend of landslide disasters increases year by year with the rapid development of economic construction. The landslide caused massive casualties and economic losses. In this paper, a new kind of stress-displacement sensor, which can monitor the stress and displacement of local points on the contact surface, is developed. A large indoor direct shear test of the contact surface between red clay in Chongqing and structure is carried out by using this sensor. Furthermore, stress and deformation response evolution characteristics of the contact surface under shear loads and different soil compactness and normal stress are discussed. The shear failure of the contact surface between soil and structure is characterized by progressive failure; the normal stress of the contact surface and the compaction degree of the soil has a significant influence on the progressive failure. The test results indicate that the peak stress along the shear direction of the contact surfaces shows obvious inhomogeneity features. Considering the progressive failure characteristics of soil, the shear strength parameters obtained by the traditional large direct shear test underestimated the soil shear strength before the peak shear stress of shear curves. Then, in the post-peak shear stress stage (post-failure zone), the residual strength obtained by large direct shear tests represents the real residual strength of the soil.


Wettability plays an important role of two phase Àuids Àow in porous media. The displacement efficiency of oil by injected Àuid is also dictated by wettability characteristic of reservoir rocks. This papers contents a highlight of the reservoir wettability modification by injecting TFSA (Thin Film Spreading Agent) surfactant for EOR applications through a laboratory study . TFSA used in this study is called Coconut Ethanolamide with a HLB (Hydrophilic-Lipophilic Balance) level around 13 to 15 which is very suitable for TFSA purposes. Several laboratory evaluations have been done to screen this surfactant with the aim of getting the best properties that fulfill the criteria for EOR chemical injection. Then TFSA solution tests have been carried out including compatibility, thermal stability, phase behavior, and filtration test. The results suggest that all measured parameters are suitable for chemical injection. Others parameters measuring rock Àuid interactions for instance: adsorption, wettability, imbibition, relative permeability, and core Àood experiments has been done to find the quantitative numbers for screening this surfactant. All experiment results categorize as moderate levels for passing the screening criteria for chemical injection except for the adsorption which is excellent. Even though the results of laboratory tests show this TFSA is valid for chemical injection, improvement by adding some chemicals is still suggested to find a better TFSA formula.


Abstract We give a simple necessary and sufficient condition for the inclusion map of a subpolyhedron into a compact 3-manifold with non-empty boundary to be a homotopy equivalence.


As user demand and cost benefits of natural user interface (NUI) technologies are hastening their adoption, computing devices that come equipped with these interfaces are becoming ubiquitous. Consequently, authentication mechanisms on them are becoming an essential security component to enable a wider range of applications that need higher requirements of security as well as privacy. In this talk we will survey the landscape of "point-of-entry" user-device authentication mechanisms based on behavioral biometrics that require a natural user interaction using gestural or non-gestural interaction for access. This interaction includes 2-D touch gestures, 3-D gestures, voice, eye tracking, and braincomputer interaction. We will analyze their potential security and usability promises and issues, and discuss plausible solutions that could be pursued in future work.


American Nurses Credentialing Center's (ANCC, 2004) Magnet Recognition Program© identifies collaborative working relationships as essential. Exploring any potential barriers to collaboration is necessary. Nurses new to the profession may lack or have a varying degree of role confidence. Nurses need to be prepared to work at the collaborative bedside. Does a confident nurse assist in closing the gap in nurse-physician collaboration? The purpose of this investigation was to identify and describe the relationship between a nurses' role confidence and nurse-physician collaboration. The convenience sample (N=90) consisted of RNs working in an acute care setting in a mid-western state. The variables were: (a) Nurse Role Confidence defined by the Nurse Self-concept subscale, the Caring subscale and the Knowledge subscale of the Nurse Self Concept Questionnaire (NSCQ) (Cowin, 2001), (b) Nurse-physician Collaboration defined by the Collaboration with Medical Staff Scale (CMSS) (Adams, Bond & Arber, 1995), (c) RN participant age, (d) RN participant years of nursing experience, and (e) RN unit worked. "Is there a statistically significant correlation between nurse role confidence and nurse perception of nurse-physician collaboration?" was the first research question. A correlation was performed with the NSCQ three selected subscales. The Caring subscale showed a statistically significant correlation with Nurse-physician collaboration. The Nurse Self-concept and Knowledge subscales were not statistically significant. The second research question, "Is there a statistically significant correlation between nurse role confidence and nurse age?" correlated the Nurse Self-concept, Caring and Knowledge subscales with nurse age. No statistically significant correlation was present. The third question was "Is there a statistically significant correlation between nurse role confidence and number of years of nursing experience?" This question correlated Nurse Self-concept, Caring and Knowledge subscales with years nursing experience. No statistically significant correlation was present. The final question was, "Is there a statistically significant difference between nurse role confidence by unit worked?" No statistically significant difference was found between unit worked and the subscales of Nurse Self-concept, Caring and Knowledge. Nurse role confidence, as defined in this investigation was not shown to have a positive correlation with nurse-physician collaboration. The Caring subscale provided a statistically significant correlation with nurse-physician collaboration. Future research for factors that impact collaboration is recommended.


We consider an asset liability model under an internal solvency constraint that includes default probability as well as price-demand functions and combine insights from empirical and theoretical research. Furthermore, as a result of policyholders' heterogeneous willingness to pay, we introduce heterogeneous premiums to maximize the insurer's overall net present value and compare the results with an optimal homogeneous premium. To determine a reservation price for the insurer, we use the Margrabe-Fischer option-pricing formula. Our numerical examples document that heterogeneous premiums for homogeneous risks improve the net present value when correct expectations underlie and are vulnerable against a cost shift but do not per se induce a decrease in the net present value. Moreover, we recognize that the optimal price setting under overall net present value maximization varies from the underwriting net present value maximization on the individual risk level. Hence, in practice, an overall asset liability management perspective should be in focus to reach the best results from the company's point of view.


Rapid rule-out of acute myocardial infarction (AMI) in chest pain patients presenting to the emergency department (ED) is central in assuring adequate triage and optimizing ED length of stay. ED physicians consider safe rule-out strategies with a negative predictive value >99% [1]. Several studies have demonstrated that this diagnostic performance can be reached with a single value of highly sensitive cardiac troponin (hs-cTn) at patient admission lower than the limit of detection (LOD) of the assay [2, 3]. Accordingly, the LOD has been recommended as the lowest reportable limit of troponin results [4]. Accurate calibration of hs-cTn assays in the low range of concentrations is therefore of the utmost importance for this application, as even relatively small analytical variations may influence the proportion of patients who could be identified as suitable for discharge, potentially leading to clinical misdiagnosis or mismanagement [5]. However, commercial internal quality control (IQC) materials usually do not cover such low concentrations, leaving the assay vulnerable to potential drifts that could remain unnoticed. There is evidence that drifts over time are associated with reagent and calibrator lot changes, platform to platform variability, and different schemes of instrument maintenance, as well as instrument decline and malfunctioning [6, 7]. With these considerations in mind, in March 2017 we elected to use a low concentration serum pool with a concentration near to the LOD of the hs-cTn T assay as an additional IQC material (IQC3), besides commercial control materials, both to identify any possible drift in the assay calibration and to monitor assay performance near the assay LOD. Here, we evaluated the impact of this additional quality tool on the performance of our laboratory in the external quality assessment (EQA) program. In our laboratory, we measure hs-cTn T on two interchangeable Cobas e411 platforms (Roche Diagnostics). Limit of blank and LOD of this assay are 3 and 5 ng/L, respectively [8]. For routine checking of the platform alignment, we run Roche PreciControl Troponin 1 and 2 materials (cat. no. 05095107190). IQC3 is prepared by pooling fresh leftover human sera at a final hs-cTn T concentration of approximately 5 ng/L, stored at –20 °C in 250 μL aliquots. A sufficient amount of IQC3 is prepared to run it on our two instruments for approximately 2 months. Before the introduction in use of each IQC3 new batch, batch-specific target value and acceptability range are determined by calculating the mean ±30% of 10 preliminary measurements, performed after verification of optimal instrumental conditions. IQC3 is then routinely assayed, together with the regular two level PreciControl Troponin material provided by the manufacturer, twice daily and after every new calibration. If IQC results, including IQC3, are "out of control", immediate corrective actions, such as recalibration or technical interventions, are undertaken before reports related to the patient samples analyzed in the affected run are issued and measurements repeated. Accuracy of our hs-cTn T measurements is evaluated by participation to the EQA for cardiac markers organized by the UK National External Quality Assessment Service. This monthly scheme consists of the assessment of four different samples and always includes a "low concentration sample" (LCS) with cardiac troponin concentrations lower than the 99th percentile limit of the reference distribution, obtained by spiking with troponin complex a serum sample from a healthy female. Lacking however the definitive demonstration of the commutability of this material, we evaluate our EQA results by comparing them with the mean value of the Roche 411 module group, i.e. participants using the same model instrument/ reagents/calibrator from one manufacturer, and applying *Corresponding author: Elena Aloisio, Clinical Pathology Unit, ASST Fatebenefratelli-Sacco, Via GB Grassi 74, 20157 Milan, Italy, Phone: +39 02 39042683, Fax: +39 02 39042896, E-mail: firstname.lastname@example.com Sara Pasqualetti, Alberto Dolci and Mauro Panteghini: Clinical Pathology Unit, ASST Fatebenefratelli-Sacco, Milan, Italy


Styrene-butadiene-styrene copolymer(SBS)/Clay nanocomposites were prepared by melt mixing method with organic clay modified with dimethyl dihydrogenated-tallow amine(Cloisite 15A) and methyl tallow bis (2-hydroxy-ethyl) amine(Cloisite 30A), respectively. From the results of XRD, we found that mono layered silicates were dispersed in SBS matrix and they were exfoliated nanocomposites. Mechanical properties of exfoliated SBS nanocomposites were more improvedl than those of SBS. Especially, it was found that the addition of small amount of organoclay was enough to improve mechanical properties without increasing hardness.


We present the first multicolor CCD photometry for the eclipsing binary V380 Cassiopeia (V380 Cas) observed on 34 nights in 2009 and 2010 at the University of Patras Observatory. The PHOEBE program based on the Wilson–Devinney algorithm was used to analyze the first complete BVRc Ic light curves. It was found that V380 Cas was misclassified and it is a well-detached system consisting of two main-sequence stars. A range of solutions found to give satisfactory fits to the observations is also investigated. The first orbital solution based on the photometric mass ratio q = 1.08 of almost equal temperatures and masses and orbital inclination of i = 86.°57 was obtained. In addition, based on all available times of light minima, including 12 new ones, a new orbital period of P = 2.714539884 days is given.

In this communication it is shown that the widely held opinion that com- pact program packages for quantum-mechanical calculations of molecular structure can safely be used as black boxes is completely wrong. In order to illustrate this, the results of computations of equilibrium bond lengths, vibrational frequencies and dissociation energies for all homonuclear diatomic molecules involving the atoms from the first two rows of the Periodic Table, performed using the Gaussian pro- gram package are presented. It is demonstrated that the sensible use of the program requires a solid knowledge of quantum chemistry.


Background: The passage of Title IX precipitated a rise in the number of female athletes, an increase in musculoskeletal injuries observed in women, and an understanding that sex disparities in musculoskeletal injuries exist. Women's musculoskeletal health programs have been created to develop sex-specific strategies to prevent and treat musculoskeletal injuries in women. The purpose of this report is to highlight the formative process of a comprehensive Women's Musculoskeletal Health and Sports Medicine Program. Methods: A half-day workshop of research presentations and networking was a preliminary step in the formative process of establishing a Women's Musculoskeletal Health and Sports Medicine Program. This workshop was aimed at facilitating communication and collaboration between subspecialties. Following the workshop, a survey was distributed to assess attendees' impressions of the workshop. Results: Nine of 11 (81.8%) respondents strongly agreed that the workshop was informative and 8 of 11 (72.7%) strongly agreed that they learned something new. Ten of 11 (90.9%) respondents strongly agreed that they would attend a similar workshop in the future. Conclusions: An event focused on defining sex disparity in musculoskeletal injuries, highlighting current research in women's musculoskeletal health, and encouraging networking among health care providers seems to be an effective means of laying the groundwork for the development of a formal comprehensive musculoskeletal health and sports medicine program for women and girls.

The emission process of polyatomic species, in particular the sputtering of metal-adsorbate molecules and metal clusters, has very recently been studied to an increasing extent theoretically and experimentally [1-5]. However, due to the small fraction of sputttered clusters, relatively few experimental data are available at present. The interest in metal clusters arises primarily because metal clusters exhibit a strong potential as catalysts and they represent an intermediate state between atoms and metals. Often already metal clusters, build up of relatively few constituents, show features close to metals.


In the context of sustainable development,environmental factors have increasingly become an important indicator for the evaluation of industrial efficiency.On the basis of the theoretical analysis of the relationship between the degree of environmental control constraints and the process of new industrialization,this paper conducts an empirical test and evaluation with DEA analyzing method on the new industrialization efficiency of Poyang Lake Ecological Economic Zone in the context of environmental control.Such conclusions are drawn that within the Zone the pure technical efficiency of industrial development is rather low,the environmental protection and economic development need to be further coordinated,etc..In order to improve the efficiency of the new industrialization in Poyang Lake Ecological Economic Zone,some measures must be taken,such as to increase investment in science and technology,to introduce more talents,and so on.
