Given any structure, we seek to find the solution of mechanical problem as precisely and efficiently as possible. Within this condition, the BEM is robust and promising development, standing out in the analysis of cases with occurrence of large stress gradients, as in problems of fracture mechanics. Moreover, in BEM the modeling of infinite means is performed naturally, without the use of appro...

the purpose of the present study was to assess job stress in medical records personnel. 117 females and 78 males were assessed by osipow et al.'s job roles inventory. data were analyzed by descriptive statistics and chi-square test. the findings indicated that the physical environment was the main source of stress for the staff of the four different units of the medical records department,...

background and objectives: one of the most important limiting factors of crop growth in the arid and semi-arid regions, is water deficit stress. mycorrhizal fungi are one of the most important microorganisms in the rhizosphere. the effects of these fungi apply via changes on some of the characteristics of roots and nutrient uptake in host plants in drought conditions. however, symbiotic mycorrh...

in order to study the effect of salt stress at different growth stages on physiological characteristics and enzyme superoxide dismutas (sod) activity in wheat genotypes a green house experiment was conducted at the agricultural research greenhouse, agricultural, medical and industrial research school, nuclear science and technology research institute of karaj. a split factorial design on the ba...

Introduction: The restoration material commonly used as core material for pulpless posterior teeth is mostly amalgam due to its high strength and low cost and it can be used with or without pin. The aim of this study was to evaluate the influence of post material on stress distribution in mandibular second premolar tooth by finite element analysis. Method: The stress distribution was analyzed i...

introduction. the professional education can be a very stressful experience. the high level of stress often leads to disruptions in physiological and psychological health. although a moderate degree of stress can promote students’ creativity and achievement, the intense pressures and relentless demands of medical education may destroy personal relationship and ultimately, affect patient care. t...
