Abstract Introduction: Multiple sclerosis is one the most common diseases of the central nervous system. Fatigue and depression are common symptoms of the disorder. The identification of the factors associated with fatigue can help to solve this problem and subsequently, reduce the problems of these patients. Objective: This study aimed to determine the predictor role of depression in...

background:. multiple sclerosis (ms) is one of the most common chronic diseases. these study aimed to examine the effects of eight weeks of massage therapy on quality of life, in women who sufferers of ms.   methods: this was a true-experimental study. we conveniently selected 20 women volunteers from referrals of the ms society of isfahan. the inclusion criteria were to suffer from relapsing–r...

In this paper, experimental fatigue behaviour of adhesively bonded PEEK composite was investigated. PEEK based materials are considered as a high performance thermoplastic materials conferring to their good mechanical properties and chemical resistant for many aggressive environments due to their semi-crystallinity property. However, it is well known that the adhesive bonding assembly of this k...

The fracture toughness is a critical material property for the pyrolytic carbon materials used in mechanical heart-valve prostheses; however, making accurate toughness measurements has traditionally been problematic due to difficulties in fatigue precracking specimens. In this work, a simple, effective, and reliable precracking method is presented where a sharp precrack is "popped in" from a ra...

Cavitation normally causes severe damage in hydraulic machinery such as pumps, valves and so on. However, cavitation impact can be utilized to surface treatment to improve fatigue strength of metallic materials in the same way as shot peening. A peening method using cavitation impact was named as “cavitation shotless peening” or “cavitation peening” as shots are not required. As increase of sur...
