The purpose of this study was to determine the Effectiveness of resilient education on reducing of perceived stress and communicative problems of women with abandoned addicted spouse. Method: The research...
Time-dependent creep analysis is presented for the calculation of stresses and displacements of axisymmetric thick-walled cylindrical pressure vessels made of functionally graded material (FGM). For the purpose of time-dependent stress analysis in an FGM pressure vessel, material creep behavior and the solutions of the stresses at a time equal to zero (i.e. the initial stress state) are needed....
The goal of this research is to determine the effect of the leadership styles on the personnel’s stress with regard to their personalities in the governmental offices of Kerman. “The expost facto research method” was used to accomplish this goal. The means for obtaining the necessary data was “questionnaire”. The statistical population was the personnel of the governmental offices of Kerman fro...
This study was conducted at the Research Farm of Isfahan University of Technology in 2003 to evaluate drought tolerance potential of 20 oat (Avena sativa L.) genotypes including 14 cultivars released in Canada, two cultivars released in the United States of America and Switzerland and four Turkish breeding lines. A randomized complete block design with three replications was used in each irriga...
The deformation of aeronautical monolithic components due to CNC machining is a bottle-neck issue in the aviation industry. The residual stress releases and redistributes in the process of material removal, and the distortion of the monolithic component is generated. The traditional one-side machining method will produce oversize deformation. Based on the three-stage CNC machining method, the q...

Abstract Introduction: Various studies have shown that stress is one of the environmental factors affecting the symptoms of patients with inflammatory bowel disease. Objective: The purpose of this study was to determine the effectiveness of mindfulness-based cognitive therapy on perceived stress in patients with ulcerative colitis. Materials and Methods: This study was a quasi-experimental s...
The selection of power transformer is very important to power sector. Most methods are utilized according to the initial cost and don’t consider the synthetical evaluation of economy and technology. Based on previous research, this paper addresses a new practical probabilistic life cycle cost model. Then, in order to demonstrate the practicability of probabilistic life cycle cost for the power ...
