Persistently sub-optimal environmental conditions constitute stress. Perception and signaling lead to protein expression changes, the activation of new biochemical pathways, and repression of others which are characteristic of the unstressed state. Protective metabolic adaptations alter physiological reactions of the whole plant. Paramount among the mechanisms are oxygen radical scavenging, mai...

this research investigates the effect of the post-cure time on the residual stresses in laminated composites. laminated composites were made of t300 carbon fibers and epoxy resin. the post-cure process was carried out at the constant temperature of 120 °c for 6 and 12 hours for two specimens. the slitting method was employed to determine through-thickness residual stress distribution of the com...

background: it has been prover that the prevalence of experiencing job related stress is very high among the dentists. this stress can be the result of factors such as poor lightening of dental office and noise. this stress can cause emotional distress and threaten dentists’ physical health and affect the quality of their life. this study is conducted to determine dentists’ professional quality...

abiotic stress are the main factors causing low growth and yield in crops. osmotic stress is an important stress and in case of salinity stress is presuming at the first step. there are different experimental and computational methods to study plant response to stress and lead to better understanding of mechanism involved in these conditions and improvement of plant tolerance to stress. upstrea...
