the purpose of the study is to show in which trimester of pregnancy is fatigue more common among working women, and whether or not there is any relationship between fatigue rate and educational level, income, etc. this is a longitudinal study. from the total number of patients who came to zeinab university hospital, 100 completed a demographics 50 item questionnaire and the numerical rating sca...

this research was conducted in order to evaluate fatigue behavior of asphalt mixes containing electric arc furnace (eaf) steel slag. after initial evaluation of the properties of eaf steel slag using x-ray diffraction (xrd) and scanning electric microscope (sem), six sets of laboratory mixtures were prepared. each set were treated replacing various portions of limestone aggregates of the mix wi...

background: surface electromyography (semg) of muscles is a non-invasive tool that can be helpful in the assessment of muscle function and some motor control evaluations. a loss of force, known as muscle fatigue is accompanied by changes in muscle electrical activity. one of the most commonly used surface emg parameters which reflects paraspinal muscle fatigue during different tasks and positio...

objectives: skeletal-muscular disorders affect the biomechanics of the human body, especially the lower extremity, with a negative effect on the biomechanics of exercise. the main aim of this study was to evaluate the effect of fatigue on the kinematic variables of knee joints during countermovement jumps in female students of physical education with valgus knee deformity.  methods: fifteen sub...

the effect of ferrite grain size on the fatigue and tensile properties of dual phase steels with a 0.25 volumefraction of martensite (vm) under different heat treatments was investigated. the heat treatments werehomogenized at 1200 oc along with several subsequent normalizations at 910 oc, resulting in differentmicrostructures and mechanical properties. after heat treatment, the obtained steels...

the effect of an electroless ni-cu-p coating on the fatigue behavior of quenched and tempered ck45 steel has been investigated. the fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. the results indicate that plating of the base steel leads to a fatigue life reduction. the d...

the relationship between fatigue and mental health in chemical warfare victims with bronchiolitis obliterans     abbasi s [1] , mehdizadeh s [2] *, moqaddam m [3]     received: 8 mar, 2013 accepted: 10 may, 2013    abstract  background & aims : fatigue is one of the most debilitating symptoms in patients with respiratory disorders. in addition, among the chronic disease, lung disease have the h...

The objective of the current study is to determine the fatigue limit of a clean and high-performance material named as HSLA-100 steel and to compare the obtained fatigue limit with that of theoretically predicted fatigue limit by statistics of extreme value (SEV) method. Also, the size of inclusions located at the site of fatigue crack nucleation on the fracture surface of the fatigue test spec...

abstract background: fatigue is the most common side effect of chemotherapy in children with acute lymphoblastic leukemia (all).acupressure is one of the most popular non‑pharmacologic methods used to reduce fatigue in other settings. the aim of the study was to evaluate the effect of acupressure on reducing fatigue among children with all compared with a placebo treatment. materials and method...

driver fatigue is one of the main causes of road accidents. this study aimed to estimate bus driver fatigue through performance measures in a virtual driving environment. the study was conducted on thirty professional male bus drivers participated in a two-hour drive session. the driver subjective fatigue was assessed by fatigue visual analogue scale (f-vas) on 10 min intervals. at the same tim...
