Grid environment for turbulent dynamics in cosmology

A recent proposal, addressing the organization and evolution of large-scale structures in the Universe, suggests a similarity between cosmological evolution and the dynamics of a turbulent fluid. In this work, we present some optimization procedures for extending the analyses of turbulent signatures in the gravitational potential energy spectrum of dark matter haloes of galaxies at different redshifts. These include the development of a parallel version of the Friends-of-Friends algorithm, for identifying the dark matter haloes, and the implementation of a grid environment. Our data are from the N-body simulations run by the Virgo Consortium. The spectra for different redshifts are computed as independent tasks, therefore, we can use parallelization and a grid environment. We employed the OurGrid middleware in such grid experiment. Here we present the first results demonstrating the feasibility of implementing a computational grid for Astrophysics in Brazil. The obtained results fully corroborate the previously found turbulent-like signatures.
Histopathological spectrum of ovarian tumors: an institutional perspective

Background: Globally ovarian tumor is one of the leading causes of cancer death among women. Ovarian tumor has varied histiogenesis, clinical behavior and malignant potential. The aims and objectives of the present study is to study the histopathological pattern and age distribution of the ovarian tumors.Methods: A total of 84 cases were studied from January 2016 to December 2016. They were reviewed and analyzed for age, histopathological findings and clinical presentations. Classification was done according to WHO histologic classification of ovarian tumors.Results: Of the 84 cases, 75% were benign, 3.6% cases were borderline and 21.4% cases were malignant. Among the histological subtypes surface epithelial tumors comprised of 66.7% followed by germ cell tumors (23.9%). Serous cystadenoma (36.9%) was the most common benign tumor followed by mature cystic teratoma (17.9%). Serous cyst adenocarcinoma (10.7%) was the most common malignant tumour. Tumors were seen over age range of 10-78 years and maximum number of cases were in the 4th to 6th decade. Younger age group primarily presented with benign tumors whereas malignant tumors were common in elderly age group.Conclusions: Surface epithelial tumors were the commonest ovarian tumor. Maximum numbers of ovarian tumors were in the age range 40-59years and malignant tumors were common in >40 years of age.
Dual effect of sympathetic hyperfunction on blood vessels in spontaneously hypertensive and stroke-prone spontaneously hypertensive rats

The sympathetic nervous system has been considered to be hyperactive from the very beginning after birth in spontaneously hypertensive and stroke-prone spontaneously hypertensive rats. This is a primary factor for the development and maintenance of hypertension via structural and functional alterations of the arteries and the heart. It is also described that the sympathetic hyperfunction probably play a protective role in necrosis of vascular smooth muscle cells in spontaneously hypertensive and stroke-prone spontaneously hypertensive rats.

Corporate Payout Policy in Japan

This paper examines cash dividends and share repurchases in Japan - discerning between keiretsu and non-keiretsu groupings of firms - during the period 1990 to 2008, a period of extensive Japanese corporate governance reform. As in the United States, share repurchases in Japan have grown strikingly across firm groupings even relative to cash dividends which have also increased. Unlike in the United States, cash dividends remain the dominant form of payout across the groupings of firms in Japan. Despite extensive corporate governance reform, the keiretsu grouping of firms exhibits a comparative reticence to alter its corporate payout policy. In particular, it remains the case that keiretsu firms disburse relatively large amounts of cash, they rely relatively heavily on cash dividends rather than share repurchases, they exhibit a greater tendency to discontinue cash dividend payouts, their payouts are relatively sensitive to earnings and these payouts respond relatively rapidly with respect to earnings. In addition, the cash dividend payouts in keiretsu firms have been relatively concentrated, while these payouts from non-keiretsu firms concentrate increasingly over time. The findings also suggest that larger firms in Japan are more likely to payout and if they decide to do so they tend to payout more. As the level of concentration of ownership in Japanese firms increases the amount of cash dividends disbursed decreases. Privatized firms are more likely to pay cash dividends and if they decide to do so and they are not keiretsu affiliated they tend to payout more.
Investigation of the aerosol–cloud–rainfall association over the Indian summer monsoon region

Abstract. Monsoonal rainfall is the primary source of surface water in India. Using 12 years of in situ and satellite observations, we examined the association of aerosol loading with cloud fraction, cloud top pressure, cloud top temperature, and daily surface rainfall over the Indian summer monsoon region (ISMR). Our results showed positive correlations between aerosol loading and cloud properties as well as rainfall. A decrease in outgoing longwave radiation and an increase in reflected shortwave radiation at the top of the atmosphere with an increase in aerosol loading further indicates a possible seminal role of aerosols in the deepening of cloud systems. Significant perturbation in liquid- and ice-phase microphysics was also evident over the ISMR. For the polluted cases, delay in the onset of collision–coalescence processes and an enhancement in the condensation efficiency allows for more condensate mass to be lifted up to the mixed colder phases. This results in the higher mass concentration of larger-sized ice-phase hydrometeors and, therefore, implies that the delayed rain processes eventually lead to more surface rainfall. A numerical simulation of a typical rainfall event case over the ISMR using a spectral bin microphysical scheme coupled with the Weather Research Forecasting (WRF-SBM) model was also performed. Simulated microphysics also illustrated that the initial suppression of warm rain coupled with an increase in updraft velocity under high aerosol loading leads to enhanced super-cooled liquid droplets above freezing level and ice-phase hydrometeors, resulting in increased accumulated surface rainfall. Thus, both observational and numerical analysis suggest that high aerosol loading may induce cloud invigoration, thereby increasing surface rainfall over the ISMR. While the meteorological variability influences the strength of the observed positive association, our results suggest that the persistent aerosol-associated deepening of cloud systems and an intensification of surface rain amounts was applicable to all the meteorological sub-regimes over the ISMR. Hence, we believe that these results provide a step forward in our ability to address aerosol–cloud–rainfall associations based on satellite observations over the ISMR.
Numerical modelling of a NATM tunnel construction in London clay

AB5TRACf: The finite element program CRItical State Program (CRISP) has bcen used to model the New Austrian Tunnelling Method (NAT:V1) in London Clay. The non-linear behaviour of the London Clay was p1odelled by a Strain Dependent ~(odjfied Cam Clay (SDMCq mooel and the tunnel lining was modelled bv col\Stant and time-dependent elastic models. 111e col\Struction process was modelled in two and three Jimel\Siol\S by removing soil elements in sequence. 111e tunnel lining was either assumed wished.in-place or introduced after the excavation of each panel. The results obtained from plane strain and three Jirnel\Sional analyses are compared to assess the importance of arching of soil ahead of tunnel face.
Theory & Methods: Estimation of the Stochastic Volatility Model by the Empirical Characteristic Function Method

The stochastic volatility model has no closed form for its likelihood and hence the maximum likelihood estimation method is difficult to implement. However, it can be shown that the model has a known characteristic function. As a consequence, the model is estimable via the empirical characteristic function. In this paper, the characteristic function of the model is derived and the estimation procedure is discussed. An application is considered for daily returns of Australian/New Zealand dollar exchange rate. Model checking suggests that the stochastic volatility model together with the empirical characteristic function estimates fit the data well.
Challenges and Changes to Tinto's Persistence Theory.

Studies investigating academic persistence compose one of the most widely reported areas of research in higher education. Tinto is most often cited in and associated with student persistence research. This paper details the origins of Tinto's theories, as well as subsequent criticisms and reformulations of those fundamental theories. The origins of Tinto's student departure theory began with his collaboration with Cullen in 1973. The academic and social integration variables from this collaboration formed the foundation for Tinto's 1975 model, while his subsequent inclusion of additional environmental variables was adapted from Van Gennep's rites of passage theory. One of the major criticisms of the Tinto model was its exclusion of the two-year college student population. Bers (1988) and Halpern (1990) were among the first to suggest Tinto's model could be applied to twoyear colleges. They also suggested additional variables, such as college major, be included as influences on student persistence. Tierney (1992) asserted that Tinto misinterpreted Van Gennep's anthropological rites of passage, which could have harmful consequences for minority students. This paper argues that research of the 1990s evidences the continuing existence of opportunities for further exploration of the basic theoretical concepts of Tinto and others. Braxton (2000) urges researchers to reinvestigate Tinto's theory of student departure. (Contains 65 references.)

The control of Nigerian women over their sexuality in an era of HIV/AIDS: A study of women in Edo State in Nigeria

HIV/AIDS remains the world’s most menacing disease of the 20th and 21st century. Two-thirds of an estimated 40.3 affected people world-wide live in sub-Saharan Africa and 77% of these are women. In Nigeria, 57% of people living with HIV/AIDS are, according to a 2005 estimate, women. The increasing vulnerability of women/girls to HIV/AIDS has been attributed to many factors. Among these, women’s control over their sexuality has been seriously implicated. Unfortunately however, very little attention has been given to this area both in the fight against the spread of HIV and as an academic inquiry. The study examines the extent to which Nigerian women in Edo state have control over their sexuality as a means of reducing their vulnerability to HIV and curbing the spread of the pandemic. Most importantly, the study examines the extent to which conclusions from two previous similar investigations in the South-West of Nigeria can be generalized. The study shows that most Edo women have a considerable level of control over their sexuality in their homes. The conditions under which such control is exercised as well as the factors that predispose the exercise of such control are discussed. Key words: Human immunodeficiency virus, acquired immune deficiency syndrome, sexually transmitted infections, Edo women.
Variables influencing survival in four generations of captive-born muskoxen

Since 1967, four generations of muskoxen have been born in captivity in Alaska (399 live births, 18 abortions and 47 stillbirths), all derived from 20 females and 8 males captured on Nunivak Island. Analysis of juvenile survival was accomplished by dividing individuals into 7 classes (not born live, born live but not surviving 48 hours, survived 48 hours but < 1 week, survived 1 week but < 1 month, survived 1 month but < 6 months, survived 6 months but < 2 years, survived 2 years). Males were more frequent among live born calves (219:178, P=0.05), but greater numbers of females survived to 2 years (62:86, P<0.01). Birthweight (X=9.75 kg, N=155) did not differ between sexes nor did it significantly influence survival. Of 463 individuals, 131 showed some inbreeding but no coefficients of inbreeding exceeded 0.25 and most were less than 0.13. Analysis of variance (Kruskal-Wallis) showed a significant (P<0.05) difference between survival of inbred and non-inbred individuals. Chi-squared tests showed a greater proportion of non-inbred calves surviving to 2 years (P<0.05) but no significant differences in perinatal mortality. Offspring of the Nunivak Island cows survived significantly (P<.01) longer than those whose mothers were born in captivity, even when only non-inbred calves were compared.
Analysis of organisations to integrate multi-agent design systems into IT landscapes

Recent contributions in engineering design research demand qualitative and quantitative criteria to analyse organisations in order to judge whether information systems in engineering design (i.e. knowledge-based engineering systems) are generally applicable within these organisations. This analysis should be carried out within the early stages of the development of these systems. The present paper is taken up this idea and focuses on multi-agent design systems (MADS) as one kind of knowledge-based engineering systems. By using the design engineering transformation system from design theory, suitable aspects of organisations (so called success factors) are developed. The actual results are qualitative criteria, which are subordinated to the success factors. In order to operationalise the criteria, applicable questions are derived. Finally, the criteria and questions deliver support to knowledge engineers in the early phases of the development of MADS. After a practical relevance has been evaluated, the success factors, criteria and questions are prepared for using them in the development of all knowledge-based engineering systems.
Teaching STEM through Horticulture: Implementing an Edible Plant Curriculum at a STEM-centric Elementary School

School gardens are ideal places for students to ask and answer questions about science. This paper describes a case study of two 3rd grade teachers and two STEM coordinators who were recruited to implement and evaluate a horticultural-based curriculum developed for this study. U Informed by the Teacher-Centered Systemic Reform model we conducted a case study analysis of the beliefs and practices of these four educators. Teachers made curricular decisions based on their confidence teaching about plants, the accessibility of curricular materials, perceptions of relevancy of lessons to academic science standards, and the time constraints. One STEM coordinator reported that the curriculum addressed academic science standards, was relevant to students’ lives, and provided hands-on inquiry activities connected to the school garden. The subsequent STEM coordinator, along with the teachers, believed that garden plants do not address science standards and instead support enrichment activities. We conclude that professional development on horticultural-based curriculum for both teachers and STEM coaches is warranted.
HEALTH-RELATED QUALITY OF LIFE (HRQOL) AMONG WOMEN WITH AND WITHOUT MEDICAL PROBLEMS DURING LAST PREGNANCY AND ITS ASSOCIATION WITH POSTNATAL DEPRESSIVE SYMPTOMS AND ADVERSE PREGNANCY OUTCOME

Background There is an increasing interest in measuring quality of life in clinical settings and in clinical trials. None of the commonly used quality of life (QOL) instrument had been validated for use postnatally. Objectives To assess the psychometric properties of the 26-item of World Health Organization Quality of Life –BREF WHOQOL-BREF among women following childbirth and to identify women with postnatal depression by using Edinburgh Postnatal Depression Scale EPDS. Methods Cross sectional study was carried out during the period from the 1 st of December 2013 to 31 st March 2014 in Baghdad, Iraq. A total number of 558 women were asked within first 48 hours after delivery to complete a questionnaire form which contains three elements (maternal socio-demographic and obstetrical variables, the WHOQOL-BREF which was developed by the WHO and EPDS). Result The study showed that the prevalence of postnatal depressive symptoms among 558 mothers was 33.5%. Most pregnant women included in study had fair QOL scores on all domains at late pregnancy. Thus, the study concluded that women who experienced medical diseases such as hypertension, diabetes and other diseases had a lower HRQOL at late pregnancy than those who were apparently healthy. Also, woman with newborns complications' (respiratory distress, low birth weight and other complications) had been experienced significant declines in psychological health. Conclusion The WHOQOL-BREF is well-accepted instrument in this sample and may be used in postnatal clinical settings or for assessing intervention effects in research studies.
Carcass physical composition and physic-chemical characteristics of meat from Nellore cattle.

Assessment of carcass physical composition and physicochemical characteristics of meat from Nellore males distributed randomly into three treatments: males castrated at 13 months of age at puberty (n=26); castrated at 18 months of age, 15 days before confinement (n=26); and young bulls (n=25). For the evaluation of meat chemical characteristics, we used samples of 12 animals taken at random from each treatment. The experimental design was completely randomized. Animals were slaughtered at 22 months of age after 100 days of confinement. The carcasses of young bulls showed higher contents of muscle (66.46 %) and bone (16.03 %), and lower fat content (17.66 %), in relation to that of steers castrated at 13 (62.83,15.28, and 22.11 %, respectively) or 18 months (63.99, 15.29, and 21.53%, respectively), which did not differ amongst themselves. The meat of young bulls was darker (3.07 points) than the meat from those castrated at 13 months of age (3.43 points), while the meat from those castrated at 18 months displayed an intermediate color (3.29 points), not differing from the others. Young bulls yielded meat with lower content of intramuscular fat (3.18 points) and lipids (3.81%) in relation to those castrated at 13 (4.58 points and 6.77%, respectively) or 18 months (4.52 points and 5.66%, respectively). Protein content was higher (P 0.05) by the age of castration, with young bulls having lower values in relation to the castrated males. Castration of Nellore young bulls in early puberty increases the edible portion of the carcass due to the higher body fat deposit.
Geostatistical inverse modeling of transient pumping tests using temporal moments of drawdown

[1] Pumping tests belong to the most common techniques of hydrogeological site assessment. While the steady state drawdown is determined by the distribution of transmissivity alone, the transient behavior is also influenced by the storativity field. In geostatistical inverse modeling the spatial distributions of both transmissivity and storativity are inferred from the drawdown curves and prior information on the spatial correlation of the parameter fields. So far, however, transient data have hardly been analyzed by geostatistical inverse methods because the computational effort is rather high. In the present study, we characterize the drawdown by its temporal moments. We present moment-generating equations and corresponding equations to compute the sensitivity of the temporal moments of drawdown with respect to the distributions of transmissivity and storativity. We utilize these equations to infer the transmissivity and storativity fields from transient pumping tests using the quasi-linear geostatistical approach of inverse modeling. Considering temporal moments rather than full drawdown curves drastically reduces the computational effort of the estimation procedure. In test cases we show that the first two temporal moments are sufficient to characterize the drawdown curves. We investigate how erroneous assumptions regarding the spatial variability of storativity affect the estimate of the transmissivity field, and we analyze the effect of truncating the measured drawdown curves.
Educational Attainment and Labor Market Performance: An Analysis of Immigrants in France

Using a recent survey of immigrants to France, we provide a detailed analysis of the educational attainment and labor market performance of various sub-population groups in France. Our results indicate that immigrants to France are less educated than the native born and that these differences can be tracked down to differences in socioeconomic background for most groups of immigrants. Similarly, there is a significant wage gap between immigrant and native-born workers, but this is reduced and sometimes disappears after correcting for selection into employment. In most cases the remaining differences in education and labor market outcomes seem related to the area of origin of the immigrant as well as where the education of the immigrant is obtained.
The Influence of Different Commercial Probiotics on Biofloc Nutrition

The intensive aquaculture industry nowadays faces two major problems, such as the decrease of water quality caused by excess metabolite concentration and a lower utilization of natural feed in the high water circulation rate. Accumulation of organic material in the pond will increase population of bacteria. The process of decomposition of organic materials by aerobic bacteria will cause a decrease in the oxygen content in water. Therefore, the conversion of toxic ammonia to nitrate is highly useful and can be successfully accomplished through the implementation of biofloc technology and maximizing the contribution of natural feed in intensifying aquaculture technology. This study aims to gain information on nutrient composition of biofloc caused by the use of different commercial probiotics through the formation of biofloc, including probiotic A, probiotic B and without probiotic. Parameters monitored in this research include biofloc nutrition (protein and fat) and other supporting parameters such as plakton diversity index, plankton domination index, C:N ratio, N:P ratio, pH, temperature and dissolved oxygen. Data analysis was carried out by Anova (analysis of variance) and descriptive. This research demonstrated that different probiotics significantly affected the protein and fat content of biofloc. Probiotics containing different bacterium in wide variety can enrich biofloc nutrient. Keywords— Bioflocs technology, Probiotics, C:N ratio, N:P ratio, biofloc nutrient
