Biochemical Profile of Nonalcoholic Fatty Liver Disease Patients in Eastern India with Histopathological Correlation

Aminotransferase assay is often used as a screening test as well as an endpoint for resolution of disease in nonalcoholic fatty liver disease (NAFLD). Aim of the study was to evaluate the relationship of transaminase level with metabolic variables and histology in NAFLD. Single center observational study was conducted in a gastroenterology clinic at Cuttack in coastal Odisha. Subjects were consecutive patients presenting with functional bowel disease and undergoing abdominal sonography. All participants were evaluated for the presence of metabolic syndrome (MS), insulin resistance, liver function test and lipid profile. Various parameters were compared between NAFLD subjects and controls. 53.5 % of NAFLD had normal serum transaminases, whereas 20.8 % of healthy controls had transaminitis. NAFLD patients had significantly higher BMI, fasting plasma glucose, serum transaminases, serum triglycerides, serum insulin and homeostatic model assessment (HOMA) IR than controls. NAFLD patients who had transaminitis had significantly higher incidence of MS and higher mean HOMA IR than those without. There was no significant difference in histopathological features between NAFLD with and without transaminitis. To conclude, over half of NAFLD subjects do not have transaminitis while transaminitis is present in a fifth of healthy people without fatty liver. Hence serum transaminase should not be used as screening test for NAFLD. NAFLD patients with transaminitis had a higher incidence of MS and insulin resistance than those without. However, there was no significant difference in histopathological features between these two groups.     

Towards a model for measuring holistic performance of professional Football clubs

This paper introduces an experimental model to measure the holistic performance of professional football clubs. The model utilizes a selection of established financial and sporting indicators, which are weighted in accordance with their perceived relative importance and in relation to components of financial management and governing body regulations. The paper uses data pertaining to clubs competing in the English Premier League to demonstrate the outputs of the model. The authors argue that although the model is experimental, it still provides a useful platform to analyse performance of football clubs through further scientific investigation.     

Agri-Manpower Forecasting and Educational Planning

Abstract

Purpose: Developing countries need to plan growth or expansion of education so as to provide required trained manpower for different occupational sectors. The paper assesses supply and demand of professional manpower in Indian agriculture and the demands are translated in to educational requirements.

Methodology: The supply is assessed from the output from agricultural education. The demand in various sub-sectors is assessed employing a mix of quantitative and qualitative forecasting tools. Based on the manpower gaps and extensive interactions with stakeholders, the manpower needs are translated into educational requirements.

Findings: The demand–supply gap in agricultural professionals would cumulate to about 200,000 by 2020, which would need additional annual supply of 10,000 each of diploma holders and graduates.

Practical implications: The study makes three main recommendations: first, to increase the supply of graduates and para-staff to cater to the emerging demand; second, agricultural education needs to meet the changing occupational structure; and third, responsibility for meeting agriculture education to be shared with the private sector.

Originality/value: The paper proposes a mixed method that could be used to forecast human resource requirement in number of sub-sectors having differential information availability and growth patterns in terms of quality and quantity. Since the approach facilitates forecasting in situations of data limitations, it has potential for similar applications in many developing countries.     

Transient growth and why we should care about it

The phrases ‘transient growth’ and ‘non-normality’ have become common parlance in fluid mechanics nowadays. We present these ideas with a simple two-dimensional system, to enable the reader to look for transient growth, as a trigger for nonlinear behaviour to set in, in a variety of situations probably having nothing to do with fluid mechanics. The article is aimed at undergraduate students of science, engineering, finance, etc., and the material is based completely on the excellent books of Trefethen and Embree, and Schmid and Henningson [1,2].     

Improved equalization and joint iterative detection

Intersymbol interference (ISI) degrades the bit error rate (BER) performance of sequential detectors such as maximum likelihood sequence detection (MLSD) and the maximum a posteriori (MAP) algorithm due to minimum distance reduction. This paper describes a novel rotation method that can increase the minimum distance and results in significant improvement in the BER performance for binary PSK and 4QAM systems when operating over severe ISI channels. Simulation results show that this method can improve the BER performance of systems employing MLSD and MAP turbo equalization by up to 4.6 dB compared to existing approaches including known precoding schemes.     

Cloud <Subscript>Micro</Subscript>atlas

We begin by outlining the life cycle of a tall cloud, and then briefly discuss cloud systems. We choose one aspect of this life cycle, namely, the rapid growth of water droplets in icefree clouds, to then discuss in greater detail. Taking a single vortex to be a building block of turbulence, we demonstrate one mechanism by which we believe droplets grow rapidly.     

3D couette flow of dusty fluid with transpiration cooling

INTRODUCTION Transpiration cooling is a very effective process to protect certain structural elements like combustion chamber walls, exhaust nozzles, or gas turbine blades in turbojet and rocket engines, from the influence of hot gases. In view of this, Eckert (1958) obtained an exact solution of the plane couette flow with transpi-ration cooling. The problem remained 2D due to the uniform injection and suction applied at the porous plates. Flow and heat transfer along a plane wall with…
