Photometric study of the over-contact binary star GSC 3822-1056

Here we present the first Johnson-Cousins VRC light curves of the over-contact binary star GSC 3822-1056. A period study and the light curve solution are also given. An extremely high rate of period increase (+11: 6s =century) was found. The origin of this period change can be: (i) partly covered light-time eect due to the orbital motion around the mass center of a possible third body; (ii) mass transfer between the components. The light curve was solved using the 1998 Wilson-Devinney Code. We examined the light curve with and without third light. Both solutions yielded a contact configuration with high temperature dierence between the components. Despite the high degree of the contact ( f = 0:57), the temperature dierence between the componentsT= Tprimary Tsecondary= 1045 K. The high mass ratio of the system and its other unusual properties suggest that GSC 3822-1056 may be a recently formed contact binary.
HPC and CFD in the Marine Industry: Past, Present and Future

This paper explores the use of Computational Fluid Dynamics (CFD) applications on High Performance Computing (HPC) platforms from the perspective of a user engaged in Naval Architecture research. The paper will consider the significant limitations which were imposed on research boundaries prior to present HPC capabilities, how this impacted development in the field and the implications for industry. One particular example is the costly experimental testing which, due to resource constraints, is generally restricted to model scale. It will then present an overview of the numerical simulation capabilities using current HPC performance and capability. With the increase of computational power and capacity, CFD simulations are proving to be more accurate and reliable. Being relatively cheaper and more time efficient, numerical methods are becoming the preferred choice within the industry compared to traditional experimental tests. Nevertheless, certain experimental procedures cannot be numerically replicated with the current levels of computational capacity. The future needs and challenges of research and development will be outlined and discussed, highlighting the significant impact exascale computing will have in the field.
Comparison of the effect of contrast medium, air, and ozone on ischemia/reperfusion injury due to experimental intussusception model

To compare effects of contrast medium, air, and ozone on ischemia/reperfusion injury due to intussusception. Materials and methods: Thirty Wistar rats were allocated into five groups (n = 6). In the control group (CG), 2 cm of colonic segment, 5 cm distal to ileocecal valve, was removed. Intussusception was performed at 5 cm distal to the ileocecal valve by pushing a proximal intestinal segment distally by stile in experimental groups. One hour later, in the sham-operated group (SG), manual reduction was performed. In the reduction groups, reduction of intussusception was performed by contrast medium (CMG, 1/1 diluted omnipaqueR, infusion rate 2 mL/min), by air (AG, Pmax = 60 mmHg), or by ozone (OG, 10 µg/mL, 0.5 mg/kg, Pmax = 60 mmHg). One hour after reduction, 2 cm of colonic segment was removed. Colonic tissues were evaluated for histopathological grades and oxidative injury markers (malondialdehyde [MDA], nitric oxide [NO], and total sulfhydryl [T-SH] values). Results: Mucosal injury score was significantly higher in AG then in CG or SG (P 0.05). MDA levels were significantly higher and NO levels were significantly lower in CMG, OG, and AG than in CG (P 0.05). Conclusion: None of the reduction methods in intussusception have superiority over others in preventing ischemia/reperfusion injury.
Studies on the Nutritional Characteristics of some Commercial Wheat Varieties of Dry Land and Wet Land Grown in Sindh Province

The present research was carried out to investigate the nutritional characteristics of some commercial wheat varieties of dry land and wet land grown in Sindh province during 2011-12 at Institute of Food Sciences and Technology, Faculty of Crop Production, Sindh Agriculture University Tandojam. Four irrigated land (Inqulab, TD-1, Sarsabz and kherman) wheat varieties and four dry land (TK-3, Marvi, PK-85, Sassi) wheat varieties were collected from their respective areas and subjected to chemical analysis. The bio-chemical characteristics of dry land and wet land wheat varieties differed significantly. Chemical analysis indicate that moisture (13.06%), protein (14.83%), dry gluten (9.03%), wet gluten (35.66%), gluten index (73.8%), starch (75.83%) and zeleny (68.66%) contents were recorded higher in wet land wheat varieties than those of dry land wheat varieties with moisture (12.66%), protein (11.9%), dry gluten (8.2%), wet gluten (32.93%), gluten index (64.53%), starch (68.66%) and zeleny (58.33%). This study reveals that availability of water and environmental factors are directly related with the nutritional characteristics of wheat varieties. This study clarify that wet land wheat varieties are better in the context of nutritional qualities.
Synthesis of P(NIPAM-co-Am)/Mesoporous Silica Composites and Their Temperature- Responsive Anion Exchange

The purpose of this study is to examine the structure and the temperature-responsive anion exchange property of amino-functionalized mesoporous silica coated with temperature-responsive copolymer, poly(N-isopropylacrylamide-co-acrylamide) (P(NIPAM-co-Am)). For this purpose, the composites which contained 0, 10, or 20 wt% of Am were synthesized. From the TG results, it was found that the amounts of copolymer immobilized on the mesoporous silica were 1.6 - 2.6 wt%. XRD patterns revealed that the structures of composites were hexagonal and almost the same as that of original mesoporous silica without polymer. At low temperature the methyl orange (MO) anions adsorbed and desorbed reversibly with changing pH of the solution, while at high temperature the MO anions did not. This temperature, at which the amount of adsorbed MO anions changed considerably, shifted to the higher temperature side with increasing the amount of added Am.
Correlation of defaults in complex portfolios using copula techniques

This work, dealing with the correlation between subportfolios in more complex portfolios, begins with a brief survey of the necessary theoretical background. The basic statistical and probabilistic concepts are reviewed. The notion of copulas is introduced along with the fundamental theorem of Sklar. After this background a numerical procedure and code are developed for correlated defaults in multiple correlated portfolio. Further on, interesting results regarding the impact of changes in correlation on the portfolio performance are investigated in the simulations. The most valuable observations regarding the expected default ratios of two subportfolios considered jointly are presented and explained with particular care. These observations are compared with theoretical results. The sensitivity of the tranche losses to correlation parameters is examined carefully. The work is concluded with a brief summary of the most significant observations and their possible impact on portfolio performance.
Simulating the Energy and Water Fluxes from Two Alkaline Desert Ecosystems over Central Asia

The Central Asia region is covered by vast desert ecosystems, where the characteristic of energy and water fluxes is different from other humid ecosystems. The application of land surface models (LSMs) in arid and semiarid ecosystems was largely limited. This paper presents a detailed evaluation of Common Land Model (CoLM) at two eddy covariance (EC) sites in alkaline desert ecosystems over Central Asia. Simulations of the net radiation (), latent heat flux (), sensible heat flux (), and soil temperature showed that refined estimate of roughness length () significantly improved the performance of CoLM in simulating turbulent heat fluxes. was increased but was decreased, which were in better agreement with the observations from EC system. The results indicated that accurate parameterization of is of crucial importance for predicting energy and water fluxes in LSM when applied in Central Asia desert ecosystems. Sensitivity analysis regarding leaf area index (LAI), , and albedo () showed that is very sensitive to but , , and soil temperature () are sensitively varying with the estimate of at the two EC sites over Central Asia.
Temporal and spatial patterns in waterborne bacterial communities of an island reef system

The bacterial 16S rRNA gene diversity of waterborne bacterial (WBB) communities was assessed using PCR/denaturing gradient gel electrophoresis (DGGE) techniques, along with sequence analysis of selected bands. 16S rRNA gene diversity varied between seasons, and significant differences were recorded between night and day. However, there were no significant differences detected between low, ebb, flood and high tides when the water body sampled would have originated from completely different areas including those off-reef. These results suggest that changes in productivity and/or vertical diurnal migrations of plankton may have greater effects than large-scale water movements effected by tidal flows. These results do not demonstrate a strong link between WBB communities and their underlying benthos. This either suggests a lack of coupling between the benthos and the water column (benthic-pelagic coupling) or that the processes are extremely rapid and efficient with strong mixing. Previous studies at this site have shown cycling between coral reef and lagoon sediments via coral mucus release and tidal transport, supporting the latter. We found a strong seasonality in the abundance and composition of WBB communities, with Alphaproteobacteria being more prevalent during winter and Gammaproteobacteria during summer, but quantitative PCR (qPCR) showed no significant differences in vibrios between seasons.
Bi-ethnic infant thermal care beliefs in Bradford, UK

Purpose – Overheating is considered a modifiable risk factor for sudden infant death syndrome (SIDS). The purpose of this paper is to explore differences in infant thermal care beliefs between mothers of South Asian and white British origin in Bradford, UK. Design/methodology/approach – This study employed face-to-face interviews with semi-structured and structured questions with 51 white British and 51 South-Asian mothers in the Bradford District, UK. Findings – White British mothers were more concerned about overheating causing SIDS whereas South-Asian mothers were more concerned about cold causing respiratory infections. However concerns around hypothermia and chills causing colds were expressed in both groups. White British mothers were significantly more likely to be concerned about their infant getting too hot than too cold and South-Asian mothers about both heat and cold (p0.001), but white British mothers on lower incomes and with poorer education expressed concern about cold more so than their b.
Capital Structure Determinant's of North American Banks and the Compensation Executive Program-An Empiric Study on the Actual Systemic Crisis

The works related to the capital structure of banks consider the requirements for minimum regulatory capital, established by the Basel agreements, as their key determinant. However, recent studies suggest that standard determinants of non-financial institutions – size, profitability, growth opportunity, tangible assets and payment of dividends, also have the power of explaining the leveraging level of banks. Thus, this work was aimed at checking whether, for those banks that hold own capital above the minimum regulatory value, the predictive capacity of standard determinants also applies to American banks that have business portfolio. As an original contribution, the work evaluated the role of the compensation program for executive managers in order to determine the capital structure of banks. The final sample was comprised by 30 banks, which observations refer to the period before (2003 to 2006) and during (2007 to 2010) the systemic crisis. The dynamic regression model with panel data confirmed the key assumption mentioned by means of the significance of the independent variables profitability and growth opportunity. At last, the variable of compensation program for executive managers has been evidenced as significant in the definition of bank leveraging, but with sign opposite to the expected one by the finance theory.
DISABILITY AND QUALITY OF LIFE AMONG OLDER MALAYSIANS

Introduction: With increases in life expectancy, more Malaysian will live to old ages. The ageing of the Malaysian population is leading to an increasing number of disabled older people, as disability is associated with increasing age. Research on disability prevalence, risk factors for disability, and consequences of disability for quality of life is important in face of the ageing population. This study assessed disability prevalence and determined factors that predict disability and quality of life among older Malaysians (ages 60+) who are community-dwelling. Methods: Data from the Mental Health and Quality of Life of Older Malaysians Survey (MHQoLOM) were used in this study, which was a national survey conducted from 2003 through 2005 that employed a cross-sectional design. A multi-stage proportional stratified sample of 2980 community-dwelling older persons in Malaysia, ranging in age from 60 to 104 years, were interviewed in the respondent’s home. Statistical procedures for the analyses included descriptive statistics, univariate logistic regression, and multivariate logistic regression.
Estimating yield curves from swap, BUBOR and FRA data

In this paper we estimate yield curves from Hungarian interest rate swap and money market data. Following general practice, we experiment with several models-differing in the functional form and objective function-and chose the model which performs best according to standard evaluation criteria. We find that the methods perform equally well in terms of residuals and out-of-sample fit; however, the smoothing spline method stands out when we consider the ability to fit the short end of the maturity spectrum, stability of estimation and plausibility of the estimated curves.
Entrepreneur's profile of health staff (HS): a SEM approach

This study aims at identifying the entrepreneurial spirit of a specific professional group: health staff (HS). In this context, the psychological and cognitive structure of the HS was compared with the non entrepreneurial HS. The study used primary data collected through a face to face and an online survey, using industry organisations and institutions, and labour unions in order to get access. The results regarding the entrepreneur’s psychological and cognitive profile supported the hypothesis that HS who have created a firm have psychological and cognitive characteristics that support entrepreneurial activities.
Global Brand Identity as a Network of Localized Meanings

In this article, we develop a semiotic model to analyze advertisement glocalization. This model focuses on the mental representations that local audiences build of a i°globali± brand identity. We demonstrate how this model fills up gaps left by a popular marketing model for global advertising. We argue that the seemingly linear three- step marketing model implies several reciprocal processes in which meaning is developed and determined. This semiotic reinterpretation of the marketing model explains how a global brand identity maintains a dynamic relation with the actual brand identity that local customers construe. To illustrate the dynamics of the semiotic model, we analyzed localizations in the Snickers campaign i°Youi¯re not you when youi¯re hungry.i± Because the semiotic model elaborates the dynamics between the professionalsi¯ discourse used in developing a campaign and the localized i°globali± brand identities brought about in receiving the campaign, the model helps to explain anthropological dynamics in designing campaigns, the arising of locally differentiated i°globali± brand identities that are the result of global campaigns and the dynamic development of global campaigns.
Potentials for Usage of Significantly Reduced Chemical Mechanisms in Numerical Modeling of Combustion Processes

The paper presents comparison of the results obtained in numerical research conducted, with the aim to simulate combustion of methane-based fuels like natural gas, Serbian gas, biogas, etc. Presented results were obtained using experimentally verified, full chemical mechanism GRI 3.0, with 325 chemical reactions, and using selected, very reduced chemical mechanism, with only two chemical reactions, based on two-step C.K. Westbrook & F.L. Dryer (WD) model. “ChemKin” software was used for all numerical simulations of chemical kinetics and “Fluent” for CFD analysis. The goal was to determine possibilities and application fields of this very reduced chemical mechanism in CFD calculations, especially in cases when flows with chemical reactions, through complex geometry of burners and furnaces, disable usage of full mechanisms.
Separating Productivity and Quality Effects from Relative Prices

Based on a general equilibrium model, we derive a relative price function which can be decomposed into productivity and quality effects. We then develop a method for inferring relative quality changes and apply that to US services versus US goods using NIPA data from 1946-2005. First, relative quality was decreasing after 1946 and has been increasing since the 1970s. Second, relative productivity and quality are negatively correlated, suggesting an endogenous link between the two. Third, productivity changes alone cannot fully explain the evolution of the services-goods relative price. This suggests that ignoring quality variations when explaining relative prices or exchange rates can lead to incorrect conclusions.
Sources of Current Account Fluctuations in Industrialized Countries

We analyze the sources of current account fluctuations for the G6 economies. Based on Bergin and Sheffrin’s (2000) two-goods inter-temporal framework, we build a SVAR model including the world real interest rate, net output, real exchange rate, and the current account. The theory model allows for the identification of structural shocks in the SVAR using longrun restrictions. Our results suggest three main conclusions: i) we find evidence in favour of the present-value model of the CA for all countries except France; ii) there is substantial support for the two-good intertemporal model, since both external supply and preferences shocks account for an important proportion of CA fluctuations; iii) temporary domestic shocks account for a large proportion of CA fluctuations, but the excess response of the CA is less pronounced than in previous studies.
Comparing Performance Of Pid And Fuzzy Controllers In The Present Of Noise For A Photovoltaic System

The main advantage of using fuzzy controller for a hard nonlinear system, for instance solar cell, is the reduction of effect of uncertainty in system control. In this paper, this prominent quality has been tried to represent more with comparing fuzzy and PID controllers. Although PID controller is a linear controller but it can control many nonlinear and industrial systems with a much better performance. Howbeit it has less robustness against uncertainty. We have indicated that if an uncertainty for example a noise or a changing in the parameter of system, enters during the operation of system, fuzzy controller will decrease the effect of it better than PID controller.
Korean proven bull (KPN) variants database based on the whole-genome resequencing data.

Korean Hanwoo cattle have been subjected to intensive artificial selection over the past four decades to improve meat production traits by national breeding program. In recent, Hanwoo also start to implement genomic selection into national breeding program. We have sequenced key ancestors, the representative individuals in each family by pedigree analysis of all Korean proven bull (called KPN) and the recent selected proven bulls using illumine HiSeq platform. Total 203 individuals are sequenced at an average of 23.6X depth. We carried out a genomewide analysis in terms of structural variants including SNPs, Indels and haplotypes and developed “Korean proven bull (KPN) genomes database” to summarize the sequencing data and variants information. Users can explore genomic information of KPN including their phenotypic information. The new database is accessible online and queries can be answered using several search options.
Characterization of two novel spindle matrix proteins in Drosophila, Chromator and Megator

We have previously described the Drosophila protein Skeletor and proposed that it is a component of a spindle matrix, a relatively static structure proposed to help organize and stabilize the microtubule spindle during mitosis. In this study, we describe the cloning and characterization of a novel chromodomain protein, Chromator, which is an interaction partner of Skeletor. Chromator interacts with Skeletor in yeast two-hybrid assay as well as in in vitro pull down and coimmunoprecipitation experiments. Chromator colocalizes with Skeletor during metaphase on a spindle-like structure but becomes concentrated on the centrosomes and spindle midzone during telophase. A recessive lethal allele of Chromator has been identified. The polytene chromosome squashes prepared from homozygous Chomator mutant larvae demonstrate severe morphological defects. These data suggest that Chromator is an essential gene and is probably required for establishing or maintaining normal chromosome structures. Its association with Skeletor and its dynamic distribution pattern also suggest that Chromator may mediate spindle matrix' involvement in mitotic processes like the pericentrosomal microtubule organization as well as chromosome
Retinoid Signaling in Cancer and its Promise for Therapy

Deregulated signal transduction is a major facet of cancer development and progression. Herein, we review the current paradigm for retinoic acid signaling, its role in cancer and potential therapeutic applications and challenges. Retinoic acid is used with remarkable success in the treatment of one of the most high-risk leukemias, acute promyelocytic leukemia; however, extending its use in the treatment of other cancers has had limited success at best. Functional studies provide clues for the poor performance of retinoic acid as a general cancer therapeutic, connecting retinoic acid signaling to both cell growth arrest and proliferation with tumor suppression and cancer progression consequences. The dualistic role of the retinoic acid signaling pathway in cancer is revealed in its gene transcription targets, cross-talk with other transcription factors, mediation of apoptotic pathways, and influence in the immune system. If the greatest potential benefit of retinoid-based cancer therapeutics is to be achieved, the many physiological roles of retinoic acid need to be considered.
Integrating Resource-based and Rational Contingency Views: Understanding the Design of Dynamic Capabilities of Organizations

Resource-based view of organisation emphasises that no organisation can be self sufficient and it will always be dependent on the environment for the fulfillment of resource needs. Further, this interaction with the environment can take various forms including manipulation, which is manifested through mergers, acquisitions and other interorganisational relationships. The rational contingency view of organisations emphasises the goals that an organisation has, which are not clearly brought out in the resource dependence view. It is attempted here to integrate perspectives from the resource-based and rational contingency views of organisations to assess how the dominant coalition would view its role in an organisation with respect to building dynamic capabilities after analysing an array of goal-resource linkage possibilities.
