introduction: cardiovascular disease is one of the greatest widespread disease and the prevalence of it is increasing worldwide. our understanding of the role of psychological factors in the incidence of the cardiovascular system has rapidly increased in the past few years. the purpose of this study was to determine the effectiveness of cardiovascular disease specific psychotherapy [csp] on the...

body psychotherapy technique (bpt) is a program that teaches people how to deal more effectively with stressors. in the present study, we evaluated the effectiveness of body psychotherapy treatment on stress and salivary cortisol level in high school girl students. this randomized clinical trials study with pre- post tests was performed on 20 female students as case group and 20 participants se...

Background & Aims: Considering the important role of stress in intensifying gastroesophageal reflux disease (GERD) symptoms, the aim of the present study was to determine the effectiveness of stress management training in reducing symptoms in patients with GERD. Methods: In the present semi-experimental study, a pre-test post-test design with control group was used. From among the patients who ...

The high residual stress in a resin-molded electronic package sometimes makes the electronic functions unstable. Therefore the residual stress in electronic packages, especially on the top surfaces of semiconductor chips, should be evaluated. The objective of this study is to present a simple method for evaluating residual stress in resin-molded semiconductor chips using a combination of experi...

in this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. geometry of sheet strip is pre-estimated by a shape function. then longitudinal, transversal and shear strains have been calculated. using both the levy-mises and the prandtl reuss equations, and also considering the bauschinger effect, stress distributions have b...
