this work presents a model for calculating the effective ‎thermal conductivity of nanofluids. the proposed model ‎includes the effects of nanoparticles and thermal conductivity ‎base fluid.we will focus on experimental of the volume ‎concentration parameter and temperature on thermal ‎conductivity, nano-fluid combination and multi-walled ‎carbon nanotubes-oxide / copper-paid deionized water. th...

c-reactive protein (crp) is an acute-phase protein synthesized predominantly by the hepatocytes in response to tissue damage or inflammation. levels of acute-phase proteins rise rapidly, during infection and after injury. we take up the study to correlate serum crp levels with other important predictive markers of outcome in copd. patient with stable copd (no exacerbation in the last two months...

according to its superficial anatomical location, the thyroid gland is easily accessible by sonography. sonography allows an exact documentation of the size and thyroid volume. the relationship between thyroid volume and anthropometric characteristics is a matter of controversy. the aim of this study was to investigate thyroid volume and its determinants in healthy adult. a cross-sectional stud...

objective(s) it is well known that prenatal stresses (ps) induce a variety of neurobiological and behavioral alterations, some of them involving the hippocampal formation. this study aimed to determine whether restraint stress influences the neuronal volume and number of granule cells in the hippocampus of adult rat offspring. materials and methods ten wistar pregnant rats were randomly divided...

determination of porosity, permeability, and pore volume compressibility of reservoir rocks and those variations with effective stress changes are of great interest in petroleum engineering. this paper has studied the influence of pore types of carbonate reservoir rocks on pore volume compressibility as well as klinkenberg permeability and porosity at different stress values. in the current stu...

using modern irrigation methods such as border irrigation is one way for an optimum usage of water. potato, for this study, was cultured in a farm located at kermanshah faculty of agriculture to evaluate the efficiency of border irrigation. the culture potato was the agria variety and the applied treatment were 50, 75, and 100 percent of potato plant`s water requirement. tapes were 12 m and the...

the density (d), speed of sound (u) and electrolytic conductivity (λ) for systems containing acetaminophen, ionic liquid {1-octyl-3-methyl imidazolium bromide, [omim] br} and water have been measured at t = 293.15-308.15 k. the measured data have been applied to calculate, standard partial molar volume ( ), hepler’s constant , apparent molar isentropic compressibility (kφ), transfer volume ( ),...

rna extraction is a prerequisite technique for gene expression studies, analyzing the etiology and disease progression, treatment effects, as well as designing the diagnostic methods. although many rna extraction kits have been commercialized, but these kits are expensive and are not accessible in some countries. many studies have shown that trizol is an applicable material for the rna extracti...

accurate prediction of pollution control and environmental protection need a good understanding of pollutant dynamics. numerical model techniques are important apparatus in this research area. so a 2500 line fortran 95 version code was conducted in which using approximate riemann solver, couples the shallow water and pollution transport agents in two dimensions by the aid of unstructured meshes...
