In this article, entropy generation on viscous nanofluid through a horizontal Riga plate has been examined. The present flow problem consists of continuity, linear momentum, thermal energy, and nanoparticle concentration equation which are simplified with the help of Oberbeck-Boussinesq approximation. The resulting highly nonlinear coupled partial differential equations are solved numerically b...

The present study was carried out with an objective of preparation and in vitro evaluation of floating tablets of hydroxypropyl methyl cellulose (HPMC) and polyethylene oxide (PEO) using ranitidine hydrochloride as a model drug. The floating tablets were based on effervescent approach using sodium bicarbonate a gas generating agent. The tablets were prepared by dry granulation method. The effec...

Background: There are accumulating evidences showing the role of adiponectin, a newly discovered adipocytokine secreted from adipose tissue, in the regulation of the ovarian function in dairy cows. The objective of the present study was to evaluate the pattern of serum adiponectin concentration during a normal estrous cycle in the postpartum dairy cows. Materials and Methods: Coccygeal vein blo...

This article presents the effect of heat and mass transfer on the blood flow through a tapered stenosed artery assuming blood as a Jeffrey fluid model. The equations governing the blood flow is modeled in cylindrical co-ordinates. Analytical solutions are constructed for the velocity, temperature, concentration and flux by solving flow governing non-linear coupled equations using Homotopy Pertu...

abstractabout 30 to 50 percent of applied nitrogen fertilizers leached from soil to ground waters which can causes environment contamination and various human health problems. the rotation type can affect nitrogen mobility rate, so it is necessary to study effect of rotation type in on nitrogen movement. in order to evaluate effects of three main rotations in khuzestan province on inorganic for...

BACKGROUND Few studies have focused on the potential relationship between parental educational level and cardiovascular risk factors among young male adults. The aim of this study was to investigate cardiovascular disease risk factors among young men and whether body mass index (BMI), serum lipids, physical fitness and smoking habits were related to paternal and maternal education. METHODS In...

The study was conducted to investigate the fatty acid profile of intramuscular fat in longissimus lumborum (LL) of three genotypic groups: Qazvinian native (Q, n=10), crossbred Qazvinian native × Saanen breed (QS, n=10) and backcrossed Qazvinian native × Saanen breed (QSS, n=9) male kids.All of kids were weaned at 75-days-old and then fed with a diet consisted of concentrate (70%) and alfalfa h...

The dependence of nanoparticle concentration on the conformation of bovine serum albumin has been studied. A very small but consistent enhancement in the tryptophan emission is observed in the presence of sub-picomolar concentration of gold nanoparticles. At this concentration, the bovine serum albumin unfolding profile in presence and absence of nanoparticles are quite similar and the protein ...

Background Understanding whether the preceding low lipid profile leads to active tuberculosis (TB) or active TB leads to low lipid profile is crucial. Methods Lipid profile concentrations were determined from 159 study participants composed of 93 active TB patients [44 HIV coinfected (HIV+TB+) and 49 HIV negative (HIV-TB+)], 41 tuberculin skin test (TST) positive cases [17 HIV coinfected (HIV...

A Proton Transfer Reaction-Mass Spectrometer (PTR-MS) has been coupled to the outlet of a Field and Laboratory Emission Cell (FLEC), to measure volatile organic compounds (VOC) concentration during a sorption experiments (Rizk et al., this issue) [1]. The limits of detection of the PTR-MS for three VOCs are presented for different time resolution (2, 10 and 20 s). The mass transfer coefficient ...
