the aim of this study was to investigate the effect of different age groups and protocol type on respiratory function in men following a progressive aerobic exercise protocol. 37 healthy males (mean age of 12.7±1.7, 34.3±4.9,52±5.7 yr) were selected voluntarily. at first, the leg ergometer was used with constant 50 rpm and the initial intensity of 50 watts and 25 watts were added every two minu...

in this article, the effect of parameters like working gap, work piece rotational speed and material removal mechanism(injection of the sic abrasive slurry and al2o3, use of diamond paste as abrasive tool) in magnetic abrasive finishing process using designing of experiments on the external surface of cylindrical work pieces of stainless steel aisi 440c to get minimum surface roughness has been...

the control of biological, hydrological and geochemical cycles of soil is the key part of the earth system. the objective of this research was to evaluate changes in soil chemical properties due to deforestation occurred in the gazafolya village, merek watershed, kermanshah province, iran. toward this attempt, 35 soil samples were collected from top soil layer using auger in early june, 2013. s...

Abstract—In this paper we consider the capacity of a single user MIMO wireless system in a Rayleigh or Ricean fading environment. It is known that a certain central limit theorem exists which states (under certain conditions) that the distribution of the standardized capacity is asymptotically Gaussian as and for some constant . However we demonstrate the surprising accuracy of a Gaussian appro...

The capacity (the maximum number of users per sector that the system can support) and the interference statistics (expected value and variance) of sectors composed of cigar-shaped WCDMA microcells are studied. A model of 5 microcells is used to analyze the uplink capacity and interference statistics. The microcells are assumed to exist in rural zone highways. The capacity and the interference s...

ABSTRACT: An attempt has been made to study and analyze the performance of a magnetic fluid based squeeze film in a rough porous parallel plate slider bearing. The bearing surfaces are considered to be transversely rough. The random roughness of the bearing surfaces is characterized by a stochastic random variable with non-zero mean, variance and skewness. A magnetic fluid is taken as the lubri...
