background fatigue is a common symptom and one of the most important issues in community psychology. this study aimed to compare the rate and severity of fatigue in male and female students of jiroft university of medical sciences and to present appropriate solutions. material and methods this descriptive-analytical study was conducted on 200 students who were selected randomly at jiroft univer...

background: joint position sense (jps) is comprised of sensory input from several sources, including skin, joint capsule/ligaments, and muscular receptors. if the muscle receptors play a leading role in detecting joint position awareness, then muscle fatigue might yield a declination in jps. the aim of this study was to evaluate if a sustained fatiguing contraction of the tibialis anterior (ank...

A model has been created to allow the quantitative estimation of the fatigue crack growth rate in steels as a function of mechanical properties, test–specimen characteristics, stress–intensity range and test–frequency. With this design, the remarkable result is that the method which is based on steels, can be used without modification, and without any prior fatigue test, to estimate the crack g...

BACKGROUND Fatigue, which interferes with one's physical and mental operation, resulting in strength reduction and weakness, is considered one of the most important issues in the workplace. In addition, it can cause diseases, occupational accidents, and a reduction in an individual's efficiency. The aforementioned effects can be aggravated by fatigue in shift workers who experience sleep distur...

this paper presents the effects of different amounts of reclaimed asphalt on fatigue life of asphalt mixtures. central composite method was used to design of experiments based on response surface method (rsm). binder type (pen 60/70 and pen 85/100), reclaimed asphalt pavement (rap) content (25, 50 and 75%) and loading strain (150, 250 and 350 micro strain) were selected as independent variables...

There have been several studies which have tried to clarify the neural mechanisms of fatigue sensation; however fatigue sensation has multiple aspects. We hypothesized that past experience related to fatigue sensation is an important factor which contributes to future formation of fatigue sensation through the transfer to memories that are located within specific brain structures. Therefore, we...
