this study investigated the influence of inoculation with an arbuscular mycorrhizal fungus (amf), glomus mosseae (nicol & gerd.) on growth and antioxidant enzyme activities (sod, cat, gupx) in shoots and roots of wheat (triticum aestivum l.) affected by three different levels of salt stress. the experiment was arranged as a factorial in randomized complete block design (rcbd) with three replicat...

objective: the goals of the study are evaluation the effect(s) of food deprivation as a social stress on testis structure. we also investigated the effects of melatonin treatment as an antioxidant component and inequality on the effect(s) of food deprivation. methods: we investigated the improving effects of melatonin and social stress (food deprivation) on 42 male rats in 7 groups including co...

drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. to evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. cultivars with two-level white seedless and khosh...

in order to investigate the effect of zinc element application on growth and some morphophysiological of maize (single cross 704) an experiment was conducted during 2010 at greenhouse. experimented design was complete randomize factorial with four replications. treatments of experiment were soil salinity (4, 8 ds.m-1 and 0 as a control) and different zinc concentration including 0, 10 and 20 mg...

drought is one of the important environmental stresses that reduce the crop growth. oxidative stress is a secondary stress due to drought and other abiotic stresses. in order to study the effect of exogenous application of hydrogen peroxide on drought tolerance of glob amaranth (gomphrena globosa l.), an experiment was conducted in greenhouse conditions. this study was designed as factorial bas...

this paper presents the results of the assembly process of a gasketed bolted flanged pipe joint for two different bolt tightening strategies, i.e. asme and industrial using torque control of preload method.  the final clamping force is achieved in four and five passes in asme and industrial strategy respectively. axial bolt stress variation, at the end of each pass, individual bolt bending beha...

Introduction: Stress has many effects on the development of systems and organs in the fetal period, and these effects appear after birth. Since hemopoietic system is susceptible to stress, effects of restraint stress were studied in offspring of pregnant rats. Methods: Pregnant rats were divided into one control and three stress groups. The control group did not receive any stress during th...

Objectives: Present study is designed to investigate the effect of stress management training by using cognitive behavioral method on stress of mothers of children with Oppositional Defiant Disorder. Methods: The study was done in a quasi-experiment designed as pre-post-test with control group. The participants were 20 mothers of oppositional defiant disorder children, ages from 4 to7 years ...
