Pressure-driven magnetic moment collapse in the ground state of MnO

The zero temperature Mott transition region in antiferromagnetic, spin S=5/2 MnO is probed using the correlated band theory LSDA+U method. The first transition encountered is an insulator-insulator volume collapse within the rocksalt structure that is characterized by an unexpected Hund's rule violating `spin-flip' moment collapse. This spin-flip to S=1/2 takes fullest advantage of the anisotropy of the Coulomb repulsion, allowing gain in the kinetic energy (which increases with decreasing volume) while retaining a sizable amount of the magnetic exchange energy. While transition pressures vary with the interaction strength, the spin-flip state is robust over a range of interaction strengths and for both B1 and B8 structures

A Comparative study on the Fasting and Post Prandial Lipid Levels as a Cardiovascular Risk Factor in Patients with Type 2 Diabetes Mellitus

INTRODUCTION: Diabetes mellitus is a major independent risk factor for cardiovascular disease (CVD).Excess abdominal fat ,assessed by measurement of waist to hip ratio, is independently associated with a higher risk for cardiovascular disease. The high cardiovascular mortality which is associated with Type 2 DM is due to a prolonged, exaggerated, postprandial state. The abnormal lipid profile in the postprandial state is more significant than the abnormal lipid profile in the fasting state in causing atherosclerotic complications in Type 2 diabetes. AIMS AND OBJECTIVES: 1. To study the fasting and post prandial lipid levels in patients with type 2 diabetes mellitus 2. To assess the significance of post prandial dyslipidemia with respect to fasting dyslipidemia as cardiovascular risk factor in these patients. MATERIALS AND METHODS: The study was conducted on 100 patients from General Medicine ward and Diabetology OPD of Government Rajaji Hospital, Madurai, and 100 age and sex matched healthy subjects as controls during the period of March 2016 To August 2016. Subjects believed to fulfill all eligibility criteria ,and none of the exclusion criteria were included in the study. METHODOLOGY: A predesigned proforma was used to collect the demographic and clinical details of the patients and the controls. By Clinical examination abdominal obesity was measured by waist hip ratio WHR>.90 in men and WHR>.80 in women were taken as having significant cardiovascular risk. Laboratory investigations fasting Blood Sugar, 2hr Post Prandial Blood sugar, fasting lipid profile and 6 hr post prandial were done. Comparison of various parameters were done and significance assessed by Student t test. One way ANOVA, Pearson Correlation and Chi square test and P value of < 0.05 was taken as significant. RESULTS: Among the 100 cases of Type 2 Diabetes mellitus,by taking value of WHR 0.90 for males and 0.8 for females, the cardiovascular risk was assessed. 96 had cardiovascular risk (50 male, 46 females). By comparing with the standard reference values of the lipid profile out of the 100 diabetic subjects 53 had fasting dyslipidemia (29 males, 24 females) and 64 had post prandial dyslipidemia (23 males, 41 females). We observed a significant increase in both fasting as well as postprandial blood glucose levels in the Type 2 Diabetic subjects, as compared to those of their respective controls. Also, the postprandial blood glucose level was significantly increased as compared to that in the fasting state in the Type 2 Diabetic subjects. But the HDL-cholesterol level was not significantly decreased in fasting as well as postprandial state in the Type 2 DM patients as compared to that of control subjectsin our study. CONCLUSION: Persistent postprandial hypertriglyceridemia may result in a proatherogenic environment leading to atherosclerosis and macrovascular disease in type 2 diabetes subjects 21. LDL oxidation in the postprandial state seems to be affected by an acute increase in glycemia. Thus, oxidative modification of LDL may contribute to higher CVD risk among diabetic patients, and elevated levels of TG may contribute to the rapid LDL oxidation seen in Type 2 DM. Hence, it is important and beneficial to estimate the postprandial lipid profile, in addition to the fasting lipid profile, in the cardiovascular risk assessment in the patients with Type 2 DM

Heat and mass transfer analysis of casson fluid flow on a permeable riga-plate

79-86Numerical analysis has been carried out for a casson fluid flow on a riga-plate with temperature dependent thermal conductivity. The physical model which governs the transport properties is solved numerically. This investigation emphasizes the consequence of variable thermal conductivity and electrically conducting magnetic field on the fluid flow. Rate of heat transfer is elevated, while the flow exposed to constructive case of variable thermal conductivity. The flow speed is enhanced for the improved values of modified Hartmann number. Correlation of the results with the similarity solutions declares the accuracy

Contributions of Sushruta to Anatomy

Sushruta, a practitioner of ancient Indian Medicine has made significant contributions to various branches of medicine. He is glorified as Father of Indian Surgery. He performed surgeries in the era when no diagnostic facilities were available. What astonishes is the favorable outcome from most of his procedures. Probably, the exhaustive knowledge of basic sciences he had would have made him a versatile surgeon. This article has compiled the contributions of this great stalwart to anatomy and interprets his perspective towards teaching this subject.Keywords: Sushruta, Dissection, Cadaver, Anatomy, Preservatio

Exploration of Corpus Augmentation Approach for English-Hindi Bidirectional Statistical Machine Translation System

Even though lot of Statistical Machine Translation(SMT) research work is happening for English-Hindi language pair, there is no effort done to standardize the dataset. Each of the research work uses different dataset, different parameters and different number of sentences during various phases of translation resulting in varied translation output. So comparing  these models, understand the result of these models, to get insight into corpus behavior for these models, regenerating the result of these research work  becomes tedious. This necessitates the need for standardization of dataset and to identify the common parameter for the development of model.  The main contribution of this paper is to discuss an approach to standardize the dataset and to identify the best parameter which in combination gives best performance. It also investigates a novel corpus augmentation approach to improve the translation quality of English-Hindi bidirectional statistical machine translation system. This model works well for the scarce resource without incorporating the external parallel data corpus of the underlying language.  This experiment is carried out using Open Source phrase-based toolkit Moses. Indian Languages Corpora Initiative (ILCI) Hindi-English tourism corpus is used.  With limited dataset, considerable improvement is achieved using the corpus augmentation approach for the English-Hindi bidirectional SMT system
