A mathematical model is considered to investigate the behavior of horizontally polarized shear waves (SH-waves) in fluid saturated porous medium sandwiched between heterogeneous half-spaces. Heterogeneity in the upper half-space is due to linear variation of elastic parameters, whereas quadratic variation has been considered for lower half-space. The method of separation of variables and Whitta...

We performed a retrospective chart review for 149 randomly selected well-child encounters to evaluate the frequency with which clinicians plot growth measurements and document growth abnormalities during health maintenance visits. Providers failed to plot at least one measurement of height, weight, and/or head circumference in 31 of 149 encounters (21%, 95% CI = 14.5% to 27.5%). Growth abnormal...

in order to evaluate the influence of different tillage methods and autumn pea cultivars (arman, hashem, ilc-482) in first cultivation on corn forage yield (variety of single cross-704) in second cultivation, this research has been done. the experiment was conducted as split-plot in rcbd with the replication of 4 in tehran university from karaj in 2012. the main plots included different tillage...

An acetaldehyde dehydrogenase from germinating peanut cotyledons has been purified and its properties have been studied. At the highest purification achieved the preparation is free of alcohol dehydrogenase activity.The enzyme is specific toward diphosphopyridine nucleotide, and can oxidize a variety of aldehydes. The highest reaction rate is obtained with acetaldehyde, which is oxidized to ace...

Using wheat germ acid phosphatase and sodium orthovanadate as a competitive inhibitor, a novel method for analyzing reversible inhibition was carried out. Our alternative approach involves plotting the initial velocity at which product is formed as a function of the ratio of substrate concentration to inhibitor concentration at a constant enzyme concentration and constant assay conditions. The ...

Dynamical parameters like average velocity dispersion and temperature profile of galaxy clusters are determined using a quasi equilibrium thermodynamic theory. The calculated velocity dispersion results from theory and simulations shows a good agreement with the velocity dispersion results of (Abdullah et al. 2011). An Adaptive Mesh Refinement (AMR), Grid based hybrid code have been used to car...

Abstract We quantify the role of geography and land quality for agricultural productivity differences across countries using high-resolution micro-geography data a spatial accounting framework. The rich provide each cell covering entire globe, potential yield 18 crops, which measures maximum attainable crop output given soil quality, climate conditions, terrain topography, level cultivation inp...

Background. It has been long believed that Parkinsonian rigidity is not velocity-dependent based on the neurological examination. However, this has not been verified scientifically. Methods. The elbow joints of 20 Parkinson's disease patients were passively flexed and extended, and two characteristic values, the elastic coefficient (elasticity) and the difference in bias (difference in torque m...
