Selenium (Se) at high concentrations can cause toxic effects in plants, whereas at low concentrations it enhances resistance to certain abiotic stresses. The possible mechanisms of the Se-enhanced tolerance of plants to salinity stress remain elusive. In this work, effect of Se supplementation at 0, 0.1, 1 and 10 mg l-1 sodium selenate was studied in Lallemantia iberica plants subjected to salt...

Background: Impairment in quality of life and mental health had been reported in the previous studies as the results of musculoskeletal disorders among workers. Mental health has a wide concept and contains different disorders including  anxiety, depression or even decreased quality of life, all of which having challengeable impacts on work- related characters such as work productivity and...

background: studies have shown that individuals with fertility problems experience psychosocial problems. the use of various coping strategies seems to have different impacts on women with infertility stress. the aim of this study was to examine the role of coping strategies (active-avoidance, passive-avoidance, active-confronting and meaning based) in predicting infertility stress among a grou...

in recent decades, the issue of stress and its negative consequences such as violence in the workplace, increased accidents at work, absenteeism and burnout, have deleterious effects on the efficiency and economy. the aim of this study was to determine the occupational stress of pelletizing industry workers and its determinants. this study was descriptive-analytical and cross sectional. among w...

since there is limited information on the simultaneous effect of drought stress and salicylic acid on yield and mucilagecontent of the medicinal herb, plantago ovata forssk is available, a pot experiment was conducted in factorial form basedon a randomized complete block design with three replications in jiroft, kerman province, south of iran. as the firstfactor, drought stress included four le...

drought is one of the most important factors limiting crop yields around the world. drought stress in plants, the change (increase or decrease) in the production of plant proteins. this research was carried out using bread wheat genotypes. for evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....

in the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized aa6061 aluminum alloy produced by equal channel angular pressing (ecap) process were investigated. the grain refinement after two passes of ecap significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. however, the improvement of low cycle fati...
