Stress is a ubiquitous condition that affects all people. Stress can be mental or physical, although in the context of this article the focus will be mental stress. Mental stress involves challenge, threat or worry about future adverse events. Such stress activates the brain’s stress response systems, which in turn affect the body. Many of the body’s major systems are altered by stress (cardiov...

water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of sb university of kerman using five wheat cultivars.xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. results showed that significant difference exists...

common vetch ) vicia sativa .l) is belong to fabaceae family and due to adaptation and tolerance to environmental stresses are considered. in this research, morphological and agronomic characteristics of 89 genotypes of common vetch ) vicia sativa .l) were evaluated in an augmented design under irrigated and drought stress conditions in research field of university of tehran at karaj in 2011. r...

Study about Fracture Mechanics and the root cause of fracture in order to estimates lifetime for Mechanical parts in designing process and manufacturing have tremendous role in this realm. Stress intensity factor comes into design which not only is dependent to geometry also extremely to load condition; for instance, it is important in failure processes (brittle and ductile Materials) or to pre...

Abstract Effects of water stress on root and leaf growth rates and their relationships with yield under normal and water stress conditions were examined at the Greenhouse and Research Field of Faculty of Agriculture, Kerman University, Iran, using seven maize cultivars including SC-404, SC-704, BC-666, TC-647, DC-370, Jeta and Kordona. During a period of 14 days, water stress at -0.4 MPa was ...

chickpea (cicer arietinum l.) is mainly cultivated in arid and semi-arid agricultural systems. drought stress is a major factor delimiting maximum yield. this research evaluated the effects of drought stress treatments on expression of cu/znsod as a gene involving in drought tolerance by real time pcr technique. to find the probable relationship between the molecular and physiological effects o...
