This study suggests that psychological morbidity was common in Iranian medical students and practitioners, particularly women. Women were at particular risk. A high prevalence of emotional disturbance among health care practitioners is likely to compound existing problems of health care provision.

Thermoplastic elastomeric nanocomposites due to their excellent mechanical, thermal, and chemical properties have a wide application in airplane, shipbuilding, and automotive industries and medical apparatus. Friction stir processing (FSP) is a novel technique for the fabrication of composites, nanocomposites and microstructural modifications. In this paper, polypropylene/ethylene-propylene-diene monomer (PP/EPDM) nanocomposite with 5 wt% nanoclay are fabricated by FSP to determine the effect of process parameters such as tool rotational speed, traverse speed, shoulder temperature, and number of passes on total work of fracture of this nanocomposite. Response surface methodology (RSM) and Box-Behnken design were used to develop a mathematical model relating the process parameters to the total work of fracture. The results show that the total work of fracture increased with increasing the rotational speed and number of passes and decreasing the shoulder temperature. A maximum total work of fracture of 50.3 N/mm was obtained at traverse speed of 42 mm/min when other parameters were at their center level. The maximum total work of fracture of 61.8 N/mm is achieved at rotational speed of 1,200 rpm, traverse speed of 40 mm/min, shoulder temperature of 1008C, and number of passes of 3. POLYM.
