BACKGROUND Natural disasters, both expected and unexpected, usually cause widespread injuries and destruction with a large number of survivors, including children. Several studies have shown that children may develop posttraumatic stress disorder after exposure to disasters such as an earthquake. OBJECTIVES This study aimed to evaluate the screening abilities of the University of California a...

BACKGROUND The objectives of this paper are three folds. First, an integrated framework for designing and development of the integrated health, safety and environment (HSE) model is presented. Second, it is implemented and tested for a large gas refinery in Iran. Third, it is shown whether the total ergonomics model is superior to the conventional ergonomics approach. This study is among the fi...

The occurrence of severe and inclusive dust storms has caused a lot damage every year in the Persian Gulf region it destructive environmental effects this area. aim study is to investigate monthly changes frequency over Khark, Kish Qeshm islands located during 10-year period (2007–2017) using satellite model observations. results show that highest was observed Island followed by Khark Islands. ...

introduction: recent studies have shown the presence of cl- channels in heart and liver mitochondrial membranes. in this work, we have characterized the functional profile of a cl- channel from rat brain mitochondria. methods: after removing and homogenizing the rat brain, the supernatant was separately centrifuged in msedigitonin, h2o and na2co3 and mitochondrial inner membrane vesicles were o...

Tubular channel angular pressing (TCAP) is a recently invented novel severe plastic deformation technique for producing UFG tubes. Plastic deformation analysis using the finite element method (FEM) was carried out to investigate the effects of trapezoidal channel geometry on strain inhomogeneity index (SII), strain level and required load compared to previously used channel geometries. The resu...

background and objectives: despite the increasing impact of heavy metal pollution in persian gulf due to urban growth and agricultural and petroleum activities, few studies have focused on the behavior and relationships of these pollutants in the biotic and abiotic components of aquatic environments. in this study, the amount of some metals (copper, iron, lead, cadmium, zinc and nickel) was det...
