recognition of relationship between the present day stress state and fractures is very important in fractured reservoirs. fractures that are parallel or oblique to maximum horizontal stress have more tendencies to tensile deformation and tensile deformed fractures will be more permeable. the dalan formation is one of the main gas reservoirs of iran witch most of the production from this formati...

the present article investigates the stress pattern system of central sarawani balochi (csb), spoken in sarawan located in sistan and baluchestan province of the islamic republic of iran, based on metrical theory as developed in hayes (1995). correspondingly, the present research illustrates the position of primary and secondary stress in mono-morphemic words, verbal paradigms, compound words, ...

in order to evaluate drought tolerance of chickpea genotypes and identifying the best indices of drought tolerance, the 20 genotypes desi chickpea plus two improved cultivars (kaka and piroz) were tested using a randomized complete block design under two irrigated (non stress) and (stress) conditions. quantitive drought tolerance and susceptibility indices such as stress tolerance index (sti), ...

the effects of chronic stress and glucocorticoids receptor antagonist (ru486) on expression of melanocortin 4 receptor (mc4r) mrna in arcuate nucleus (arc) of male rats were evaluated. in this study, adult male sprague dawley rats were placed into four groups (n=6/group) stress, ru486, stress/ru486, and control groups. in stress group, the rats were restrained, 1 h/day, for 12 days. in ru486 gr...

background: occupational stress has physical and psychological consequences, and is a major cause of job dissatisfaction among employees, which can reduce the quality of services provided. this study was conducted to examine the relationship between job stress and the prevalence of musculoskeletal disorders (msds) among computer users in hospitals (private & governmental) of gorgan, iran, in 20...

The triaxiality of the stress state is known to greatly influence the amount of plastic strain which a material may undergo before ductile failure occurs. It is defined as the ratio of hydrostatic pressure, or mean stress, to the von Mises equivalent stress. This paper discusses the effects of stress triaxiality on yielding behavior of anisotropic materials. Hill-von Mises’s criteria for anisot...

stress is a physiological reaction to the ever-increasing demands of life. after each stressful event, the body should be returned to a normal relaxed state. however, continuous stress of modern life sometimes put the subjects at risk of developing a range of diseases; from psychosomatic to anxiety disorders. stress management program gives a range of tools to reduce the impact of stress and pr...

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...

to evaluate the effects of drought stress and re-watering on nodal roots initiation and growth, two glasshouse experiments were conducted in commonwealth scientific and industrial research organization (csiro) in australia during 2008-2009. the experimental designs in both experiments were factorial in a randomized complete block design with two factors. first factor was drought stress and seco...

stress is a threatening factor that all living organisms encounter throughout life. depending on the type of stress, there are several mechanisms for keeping body homeostasis to minimize stress effects. brain is an organ which shows high sensitivity to stress conditions. although many studies have shown induced-stress effects on rat embryos, little is known about the mechanisms involved in copi...
