Background and Objective: Different morphologies are factors for the effectiveness of training programs on subjects. The aim of this study was the effect of 8-week Tai Chi exercise on static and dynamic balance in women with multiple sclerosis (MS) with emphasis on mesomorph and endomorph's morphology. Materials and Methods: In a clinical trial, 48 patients with MS were purposefully select...
introduction: attention deficit / hyperactivity disorder (adhd) is a persistent pattern of inattention and/or hyperactivity - impulsivity behavior. adhd is frequently accompanied by developmental coordination disorder (dcd). motor coordination is a complex performance of interaction between visual perceptual, neuromuscular coordination, memory, attention and balance. one of the most important p...
terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
in the current study the effect of casimir force and squeezed film damping on the pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems is investigated separately. linear elastic membrane theory is used to model the static and dynamic behavior of system for strip, annular and disk geometries. squeezed film damping effect is modeled using...
Objectives: The purpose of this study was to investigate relationship between body composition indices with static and dynamic balance and rate of falling in active elderly people. Methods & Materials: This research was a correlation study. Active elderly women volunteered for participation in this research (n=45). Body composition indices (body fat mass, fat free mass, body mass index, wais...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
The viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are ...
It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...
Cortical control of the sensory output of muscle spindles was studied in thirteen anesthetized cats in the present experiment. Gamma motoneuron activity was monitored during electrical stimulation of the sensorimotor cortex while recording from single primary afferents from the tenuissimus muscle. Findings are as follows: 1. The state of anesthesia is crucial in obtaining reproducible resu...
