Research on the dynamic behavior of the arc between contacts of DC contactor

Based on magneto-hydrodynamics (MHD) theory, an air arc model is set up for the contacts and arc inducing plate at chamber inlet of a certain type of DC contactor and the dynamic behavior of the arc is simulated. The variation laws of arc length and the main conductive area migrating from moving contact to arc inducing plate were studied quantitatively under the influence of breaking speed and the applied magnetic field. The relationships between the change of breaking condition and position of conductive area, the migration time of area with high conductivity are revealed. And the experimental platform is set up to study arc dynamic development process of DC contactor which is consistent with the simulation results under the same conditions. The research of this paper has certain guiding significance for improving the breaking capacity of DC contactor and optimizing the structure of arc extinguishing chamber.
Congenital contractural arachnodactyly. A heritable disorder of connective tissue distinct from Marfan syndrome.

Congenital contractural arachnodactyly is a newly delineated, dominantly inherited syndrome of multiple congenital joint contractures, arachnodactyly, deformed ears, and kyphoscoliosis. The importance of differentiating this syndrome from Marfan syndrome and arthrogryposis multiplex congenita, the two disorders it most closely resembles, is emphasized because of the different natural history of this disorder.
Analyse et mise en oeuvre de nouveaux algorithmes en méthodes spectrales. (Analysis and Development of New Algorithms in Spectral methods)

Cette these est composee de trois parties. Dans la premiere, nous considerons un systeme d'equations Reynolds Averaged Navier-Stokes en 3D, modelisant le couplage de deux fluides turbulents ( par exemple, ocean/atmosphere). Nous proposons un schema numerique, et nous montrons sa convergence vers l'unique solution du modele. La seconde partie est consacree a une extension des methodes spectrales dans des geometries complexes. Cette nouvelle methode s'appuie sur deux idees: traitement des conditions aux limites de Dirichlet par penalisation, en suivant la methode de Nitsche, et une approximation de la geometrie par des paves, en utilisant une octree (par exemple). Nous donnons des erreurs de projection polyomiale et des estimations a priori. Enfin, la derniere partie est consacree au calucl scientifique ou on a implemente en C++ et valide cette methode dans le logiciel FreeFem3d.
Context Transfer and Q-Transferable Tasks

This article discusses the notion of context transfer in reinforcement learning tasks. Context transfer, as de-ﬁned in this article, implies knowledge transfer be-tween tasks that share the same environment’s dynamics and reward function, but have different state and action spaces. For example, we have a working mobile robot in an environment. At some point, we decide to upgrade its sensors and/or actuators. Any change in these modules will result in a different description of the agent-environment model, and the trained knowledge is no longer applicable. We consider the tasks of the old and new robots, as the source and target tasks, respectively. The Markov decision process (MDP) of these tasks, under certain conditions, are called Q -transferable tasks, and the problem of knowledge transfer between them is called context transfer. We investigate the relation of the MDPs of these tasks.
The Importance of Dividends in Declining Markets: The Case of Thailand

We present empirical evidence on the relevance of dividends in the Thai market. The study outcome reveals that investors are not indifferent regarding firms payout policy, and dividend-paying firms have a superior performance during both declining and advancing markets, but with a clear advantage for the first type. That is, Thai shareholders prefer dividend-paying stocks more in periods where the economy is not performing well. The results are not driven by investors’ preference for large and profitable firms, which in average pay larger dividends, but rather by the prospect of receiving dividends during economic downturns. The findings confirm that dividend payout policy is not irrelevant in the Thai context and provide important insights on the motivations firms have to pay dividends, further advancing the understanding of the dividend payout “puzzle”.
Effect of sucrose in culture media on the location of glucosyltransferase of Streptococcus mutans and cell adherence to glass surfaces

Streptococcus mutans strain B13 (serotype D) almost exclusively produced free glucosyltransferase (GTase) in the culture supernatant when grown in sucrose-free TTY broth medium, which was composed of Trypticase (Baltimore Biological Laboratory [BBL] Cockeysville, Md.), tryptose (Difco Laboratories, Detroit, Mich.), yeast extract (BBL), salts, and 1% glucose. Organisms grown in sucrose-free TTY broth retained very weak cell-associated GTase activity and did not adhere significantly to glass surfaces in the presence of exogenous sucrose. If sucrose was added to TTY broth, however, GTase was found on the cell surface where cell-bound, water-insoluble glucans were synthesized. Most commercially available products of Todd-Hewitt broth were found to contain trace amounts of sucrose, as did Trypticase soy broth (BBL), whereas brain heart infusion broth (Difco and BBL) was found to be essentially free of sucrose. Almost all detectable GTase activity was cell associated when S. mutans B13 was grown in Todd-Hewitt or trypticase soy broth. Heat-treated B13 cells grown in Todd-Hewitt broth and cell-free, water-insoluble glucans bound free GTase and produced marked adherence in the presence of sucrose. Experiments strongly suggest that the binding sites for free GTase are the surface glucans, and cell-associated and extracellular GTases are most likely alternate states of the same enzyme protein.
Auditory circuit in the Drosophila brain

Most animals exhibit innate auditory behaviors driven by genetically hardwired neural circuits. In Drosophila, acoustic information is relayed by Johnston organ neurons from the antenna to the antennal mechanosensory and motor center (AMMC) in the brain. Here, by using structural connectivity analysis, we identified five distinct types of auditory projection neurons (PNs) interconnecting the AMMC, inferior ventrolateral protocerebrum (IVLP), and ventrolateral protocerebrum (VLP) regions of the central brain. These auditory PNs are also functionally distinct; AMMC-B1a, AMMC-B1b, and AMMC-A2 neurons differ in their responses to sound (i.e., they are narrowly tuned or broadly tuned); one type of audioresponsive IVLP commissural PN connecting the two hemispheres is GABAergic; and one type of IVLP-VLP PN acts as a generalist responding to all tested audio frequencies. Our findings delineate an auditory processing pathway involving AMMC→IVLP→VLP in the Drosophila brain.
Feed intake, nutrient digestibility, nitrogen utilization, and ruminal fermentation activities in sheep fed Atriplex halimus ensiled with three developed enzyme cocktails

The effects of feeding Atriplex halimus treated with three developed enzyme cocktails to Barki sheep on feed intake, nutrient digestibility, N utilization, and ruminal fermentation were assessed. A. halimus was ensiled with two developed enzyme cocktails of ZAD1 ® (Z1) and/or ZAD2 ® (Z2) as liquid enzyme preparations (2 l/t) with 5% molasses and ensiled for 30 days. Three Barki rams (45 ± 3.2 kg) were used per treatment in five consecutive digestibility trials, while three ewes fitted with a permanent rumen fistula were used as source of inoculum for in vitro rumen fermentation trials. Barley grain (300 g/animal/day) was fed as energy supplement during the experimental trial for all diets. Five diets were composed as follows: A. halimus (leaves and stems) (D1); untreated A. halimus plus 4 g/animal/day ZADO ® (Z) (enzyme preparation in powder form) (D2); A. halimus ensiled with Z1 and barley plus 4 g/animal/day Z (D3); A. halimus ensiled with Z2 and barley (D3) plus 4 g/animal/day Z (D4); A. halimus ensiled with a combination of Z1 and Z2 (1 : 1) and barley plus 4 g/head/day Z (D5). For all trials, ad libitum A. halimus was offered twice a day at 9:00 and 16:00 h while barley grain was given once a day at 10:00 h. Both D1 and D2 diets increased (P < 0.001) dry matter intake of A. halimus and total dry matter intake. Addition of 4 g/day of Z to Z1 and/or Z2 ensiled diets improved (P < 0.0001) organic matter, crude protein, crude fibre, and neutral detergent fibre digestibilities. Diets D1 and D2 increased (P < 0.001) N intake, whereas the direct addition of Z to D3, D4, and D5 decreased (P < 0.001) N balance and N balance/N absorption ratio. Sheep fed on Z in addition to Z2 ensiled A. halimus showed higher improvements for total volatile fatty acids (P < 0.001), ammonia N (P = 0.007), and microbial protein production (P = 0.003). It can be concluded that feeding sheep on A. halimus ensiled with Z1 and Z2 with direct feeding of Z enzyme preparation improved intake, digestibility, nitrogen balance and utilization, as well as rumen fermentation.
A Fast Segmentation Method for STL Teeth Model

Based on fast marching watersheds and marker-controlled method, a teeth model segmentation algorithm for Virtual Orthodontics System is presented in this paper. Three critical techniques: interactive marker, threshold setting and stack operation theory, is used in the algorithm . To reduce stack operations, a combination technique of automatic threshold setting and manual threshold regulating is proposed, which obviously overcome the difficulty in intuitional segmentation control, solve the maneuverability of threshold, improve the segmentation quality and reduce the running time of segmentation process. The output results show that the segmentation algorithm in the paper has high efficiency and excellent segmentation outcome.
THE IMPACT OF CSR PERCEPTIONS ON MUTUALISTIC VALUES AND THEIR IMPACTS ON BRAND LOYALTY AND RESISTANCE TO NEGATIVE INFORMATION

Corporate social responsibility (CSR) practices are critical to strengthen the relationships between mutualistic banks and their customers. This study aims to identify the impacts of customer perceptions of CSR (the ethical and commercial dimensions) on the perceptions of mutualistic values and their impacts on brand loyalty and resistance to negative information. Mutualistic values (MV) are analysed because mutualistic institutions base their activities not only on the intention to maximise profit but also on adding social value. The research uses data collected through a structured questionnaire from a sample of 391 customers of mutualistic banks in Portugal. In order to operationalize the variables, scales used in existing studies were adapted. Besides that, a new scale to measure MV has been developed. Structural Equations Modelling (SEM) was used to test the investigation model and to provide answers to the proposed hypotheses. The results show that CSR perceptions impact on mutualistic values and that both impact on brand attitudes like loyalty and resistance to negative information. The commercial dimension of CSR seems to have a more relevant impact.
Electronic Communications of the EASST Volume 49 ( 2012 ) Proceedings of the First International Workshop on Bidirectional Transformations ( BX 2012 ) Delta Lenses over Inductive Types

Existing bidirectional languages are either state-based or operation-based, depending on whether they represent updates as mere states or as sequences of edit operations. In-between both worlds are delta-based frameworks, where updates are represented using alignment relationships between states. In this paper, we formalize delta lenses over inductive types using dependent type theory and develop a point-free delta lens language with an explicit separation of shape and data. In contrast with the already known issue of data alignment, we identify the new problem of shape alignment and solve it by lifting standard recursion patterns such as folds and unfolds to delta lenses that use alignment to infer meaningful shape updates.
Clinical Dementia Rating Performed Several Years prior to Death Predicts Regional Alzheimer’s Neuropathology

Aims: To assess the relationships between early and late antemortem measures of dementia severity and Alzheimer disease (AD) neuropathology severity. Methods: 40 residents of a nursing home, average age at death 82.0, participated in this longitudinal cohort study with postmortem assessment. Severity of dementia was measured by Clinical Dementia Rating (CDR) at two time points, averaging 4.5 and 1.0 years before death. Densities of postmortem neuritic plaques (NPs) and neurofibrillary tangles (NFTs) were measured in the cerebral cortex, hippocampus, and entorhinal cortex. Results: For most brain areas, both early and late CDRs were significantly associated with NPs and NFTs. CDRs assessed proximal to death predicted NFTs beyond the contribution of early CDRs. NPs were predicted by both early and late CDRs. NPs were predictive of both early and late CDRs after controlling for NFTs. NFTs were only associated significantly with late CDR in the cerebral cortex after controlling for NPs. Conclusions: Even if assessed several years before death, dementia severity is associated with AD neuropathology. NPs are more strongly associated with dementia severity than NFTs. NFTs consistently associate better with late than early CDR, suggesting that these neuropathological changes may occur relatively later in the course of the disease.
A Note on Comparing Several Poisson Means

There has been a renewed interest lately in comparing the means (rates) of several Poisson distributions (processes) due to its wide applicability in various fields, especially in life sciences. In this article we first review the recent developments in the literature, and then propose a parametric bootstrap method which performs as good as, if not better than, the existing methods. Results of our comprehensive simulation study have been provided to compare the relevant methods. Finally these methods have been used to four real-life datasets including a most recent one obtained from a clinical trial on the Intrinsa hormone patch developed by Proctor & Gamble.
Intervening sequences in the ribosomal RNA genes of Ascaris lumbricoides: DNA sequences at junctions and genomic organization.

An rDNA size class in the genome of the nematode Ascaris lumbricoides is described which is interrupted by a 4.5‐kb long intervening sequence located in the 26S coding region. This molecular form occurs in approximately 15 copies per haploid genome and amounts to approximately 5% of the total nuclear rDNA. Intervening sequences are present only in the 8.8‐kb rDNA, but not in the 8.4‐kb rDNA repeating units of A. lumbricoides. Cloning of the interrupted rDNA units revealed, in addition to the main 4.5‐kb insertion, shorter intervening sequences of 4‐kb and 119‐bp length. Both shorter rDNA forms are present in the single copy range of the haploid genome. Sequence analyses of the intervening sequence/rDNA junctions show an identical right‐hand junction for all of the three different rDNA forms. The two shorter intervening sequences are a coterminal subset of the right‐hand end of the main 4.5‐kb insertion, whereas all three insertions have a different left‐hand junction with the coding region of rDNA. Each intervening sequence is flanked by a short direct repeat of variable length, being only once present in the uninterrupted rDNA. The intervening sequences of A. lumbricoides show striking similarity to the organization of type I insertion family in dipteran flies, even though they are inserted at different positions in the 26S coding region. Additional rDNA intervening sequences may be present outside of the rDNA cluster, but in not more than 15‐20 homologous copies per haploid genome.
The clinical utility of TORCH testing of pregnant women from northeastern Romanian population: Application of electrochemiluminiscence assay

The accurate diagnosis of pregnant women for congenital infections is very important for the health of new-borns. We have used a highly sensitive assay - electrochemiluminiscence (ECLIA), in order to assess the prevalence of antibodies IgM and IgG type against cytomegalovirus, rubella virus and Toxoplasma gondii in pregnant women. None of the tested women were at risk for congenital infections, as we did not detect any IgM antibody present.
The Impact of Service Quality on Customer Satisfaction: A Study on Selected Retail Stores in India

Shopping in India has undergone a revolution with the introduction of modern formats, multiple channels and huge shifts in consumer buying behavior. Modern retailing has entered into India as is observed in the form of sprawling shopping centers, multi-storied malls and the huge complexes that offer shopping, entertainment and food all under one roof. Several studies have shown that customer satisfaction in retailing depends to a large extent on the perceived quality of service offered by the retailer. Managing perceived service quality means that the firm has to match the expected service and perceived service to each other so that consumer satisfaction is achieved. This paper aims to understand the importance and impact of service quality on the satisfaction of customers in selected retail stores in 3 Indian cities using SERVQUAL and GAP models. The paper also looks at the various service quality models and tries to assess their relative importance in successfully measuring service quality. Weighted averages and analysis of variance is applied in relevant places in order to critically examine the customers’ perception towards service quality which will ultimately contribute information for the growth of performance of the organized retail outlets.
E-BANKING IMPLEMENTATION AND TECHNOLOGY ACCEPTANCE IN THE RAFIDAIN AND RASHEED BANKS IN IRAQ: AN EMPLOYEE PERSPECTIVE

In the third millennium, e-banking system has been ad- opted globally in the banking industry. On the other hand, Iraq as a nation with less developed IT adoption has not integrated this system in its banking services, instead of its current acknowledgement on the advantages of e-banking technology in competition among banking service provid- ers. In contrast, Iraqi banks still keep on adopting tradi- tional banking system to deliver the majority of their ser- vices which in this case are paper-based work system. This is greatly resulted from the hesitation of bank employees to adopt new banking technologies. This study aims to identi- fy the impact of hypothesis between e-banking system and Iraqi banks employee perspective. This study was conduct- ed by taking sample of employee from two biggest public banks in Iraq which are AL-RAFIDAIN and AL-RASHEED. A survey through questionnaires on the website was used as the instrument to collect the data were analyzed us- ing PLS software. Technology Acceptance model(TAM) as a basic foundation with independent variables Perceived Usefulness, Perceived Ease of Use, Perceived IT Beliefs and Task–Technology Fit, Attitude as Intervening and Inten- tion to Use as dependent variable. The result of hypothesis analysis reveals that there is a significant impact among all variables to attitude, but Perceived Ease of Use, it does not apply variable from those analysis it is depicted that Perceived Ease of Use does not impact to the perception of the implementation of e-banking system in Iraqi banks. Keywords:E-banking System, Acceptance Theory model (TAM), Perceived IT Beliefs, Task–Technology Fit, Attitude, and Intention to Use.

Scull's Dilemma

Few psychiatrists now take a lively interest in the social sciences, and few social scientists listen to what psychiatrists have to say. For the handful who do, the widening gap between the two fields of knowledge is regrettable, for we have much to learn from each other. The gap seems to have grown for two reasons: psychiatrists, increasingly occupied with pharmacotherapy, have drawn closer to general medicine, and there is comparatively little interest in the social therapies which seemed to offer so much promise back in the 1950s. The open-door system was a success, and so was the idea of community care, even if the practice left much to be desired. Incidentally, these developments destroyed many of the interesting experiments in group dynamics which were at one time a feature of mental hospital life. Social workers, once seen as allies, went off on their own in the new, powerful and largely incomprehensible Social Services Departments, where they had many other tasks to occupy them. Sociologists became shrill and hostile. Many psychiatrists ceased to read sociology after the publication of Goffman's Asylums (Goffman, 1961) because it seemed that sociology was off on some kind of egotrip which was deeply antithetical to their own professional experience. People who talked about “madness” instead of “mental illness”, rejected diagnosis as labelling, and regarded mental patients as victims of a capitalist plot were (and are) difficult to talk to. One of the distinguishing features of mental health reform over the past 200 years has been its apolitical nature—people of all political views could agree on what seemed essentially a matter of common humanity. Suddenly it became highly politicized, both in theoretical terms, since the new analysis was basically neo-Marxist, and in the action of pressure groups in the Civil Liberties lobby. Confused by the Right to Treatment, the Right to Refuse Treatment, the Right to Information and the Right to Confidentiality, most psychiatrists have (wisely in the circumstances) kept their heads down and got on with the job.
CORPORATE ENTREPRENEURSHIP IN SMES DURING THE SEARCH FOR

The present paper illustrates, through three Danish/Dutch case studies, how several of the characteristics connected with SMEs entail significant reasons to make use of corporate entrepreneurship as a search strategy for discontinuous innovation. Characteristic dimensions of corporate entrepreneurship are researched, and pro-activity, risk-taking and autonomy are in particular found to be significant elements of the approach applied. The way these dimensions are implemented, counterbalances the resources constraints in terms of human, social and financial capital found in the SME setting. Competitive aggressiveness is found to be only indirectly influential as a way for the case firms to stay ahead of other firms by knowing what developments are made on shared technologies or part components.
