asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. this is mainly prompted by the unsatisfactory performance of traditional road materials exposed to dramatic increases and changes in traffic patterns. this paper presents the evaluation of fatigue behaviour of nano reinforced stone mastic asphalt mixtures. fatigue...

background: muscle fatigue is an important issue in neuromuscular rehabilitation. better control of this phenomenon would result in better prevention of its consequent physiological damages. objective: to provide a mathematical representation of muscle fatigue as a function of time. methods: we conducted this study by combining the emg-based estimation methods of muscle activation with the avai...

objectives: this study was designed to evaluate the psychometric features of the persian version of the fatigue impact scale (fis-p) tool when used in iranian ms patients. methods: 140 ms patients and the equivalent number of healthy controls completed the following assessments: fis-p, fatigue severity scale (fss), sf-36 questionnaire and  the mini-mental state examination (mmse).  results: a s...

 Background: The purpose of the present study was to evaluate the psychometric properties (validity and reliability) of the Persian version of the Sustained Auditory Attention Capacity Test in children with attention deficit hyperactivity disorder. Methods: The Persian version of the Sustained Auditory Attention Capacity Test was constructed to assess sustained auditory attention using the meth...

original article   shift work is a common work schedule that has several inappropriate consequences, the most important of which is fatigue. the aim of this study was to invest gate the impact of the shift length on the occupatio al fatigue of operators in filling stations. this cross-sectional study was carried out on operators of the filling station in national iranian oil products distributi...

background: cancer can lead to fatigue and the manifestation of psychological symptoms in patients, including depression, anxiety, and stress. objectives: the aim of this study was to investigate the relationship between fatigue and psychological symptoms in patients with gastrointestinal cancer. materials and methods: the study had a descriptive, cross-sectional design. we assessed levels of f...

fatigue behavior of a vanadium microalloy steel has been studied in this research. here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. the results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. optimal heat treatment cycle of the microalloyed stee...

The authors used high-resolution computed tomography (HRCT) for studying 52 congenitally malformed ears in 45 children between five and 10 years of age. In six children the malformations were bilateral. The malformations clinically manifested as microtia, atresia of the external auditory canal and conductive deafness. Analyzing anatomical details and pathological changes on HRCT axial sec...

normal 0 false false false en-us x-none ar-sa background: circadian rhythm sleep disorders are a presentation of sleep disorders in patients with multiple sclerosis (ms). this study aims to compare this problem in ms patients with healthy people and to determine its association with chronic fatigue in ms patients. materials and methods: a case-control study was performed on 120 ms patients and ...

abstract background: the aim of this study was to determine the auditory performance of congenitally deaf children and the effect of cochlear implantation (ci) on speech intelligibility. methods: aprospective study was undertaken on 47 children in a pediatric tertiary referral center for ci. all children were deaf prelingually and were younger than 8 years of age. they were followed up until 5 ...
