background post-traumatic stress disorder (ptsd) comprises a collection of symptoms following exposure to injury-causing accidents of life. it is estimated that the prevalence of ptsd in children with malignancy and their parents is between 10-30% and even several years after treatment of malignancy this disorderremain in 20-20% of these patients. objectives this study investigated the prevalen...
in the present study, vibration of cylindrical laminates with different layers and angles were studied. in order to actuate and polarize in radial direction, a piezoelectric layer was located at outer surface of composite shell. laminates were assumed long enough so that plane strain state analysis in 2d can be used properly. in order to satisfy the boundary conditions, variables in terms of fo...
metabolic syndrome (mets) as a collection of obesity-associated disorders is associated with inflammation, oxidative stress, pro-thrombotic state, elevated risk of developing cardiovascular disease and type 2 diabetes. adiponectin is one of the most abundant peptide hormones derived from adipose tissue. this protein plays a major role in glucose and lipid metabolism and prevents development of ...
* m1, f2, m3, e4, d5 abstract background: with regard to the importance of mental health in student category particularly for military students, owing to the stress and tension in the military atmosphere which leading to insecurity, reducing the efficiency, and anxiety in these students, therefore this study has been done to investigate the prevalence of state and trait anxiety and its relation...
One of the surface defects that arise in sheet metal working is when the part removes from the die. Since there are no external forces to make this defect, the origin of such fail is known as residual stress. Residual stress can develop in sheet metal forming due to non uniform deformation. In this paper, the workpiece is carbon steel with different volume fractions and arrangement of ferrite ...
Background &Aims of the Study: Nowadays heat stress is one of the most current harmful physical agents in workplaces. Attentions to recognized consequences of heat stress and have no information about heat stress in Ardabil bakeries, this study have been done in 2013. Materials & Methods: This cross sectional research has been done in 96 different bread types bakeries in ...
Lack of the proper conjunctive use of surface and groundwater resources causes large water stresses in one of these resources. Conjunctive use of surface and groundwater, especially in arid and semi-arid regions, is a scientific and practical solution for sustainable water resources management. The aim of this research was to prepare some mathematical modeling to apply the conjunctive use of su...
