implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...
triamidefon is a triazole derivative, which have both fungicidal and plant growth regulator (pgr) properties, and also protect plants from several types of abiotic stresses. the influential mechanism of triamidefon on plants is not much studied. in this study effect of this compound on the drought stressed in tomato plants was investigated. the plants were subjected to 5 day interval drought st...
Introduction: It is well established that stress or the use of sulpiride, an antipsychotic, disrupts the reproductive system. Translocator protein (TSPO) in the mitochondrial membrane of steroidogenic tissues, such as gonads, is involved in the regulation of steroid hormone production by transporting cholesterol into the mitochondria. The present study aimed to investigate the effects of stress...
Introduction: Some evidence demonstrates endogenous inhibitory pathways of pain involved in the interphase (phase between early and later phase) of the formalin test. We previously showed that swimming stress modulates the pain-related behaviors during the interphase of the formalin test. In this study, we evaluated the role of the endogenous opioid system in modulating nociceptive responses of...
Introduction: Video games are common cultural issues with great influence in all societies. One of the important cognitive effects of video games is on creating stress on video players. The present research objective was to study different types of stress in players based on video game styles. Methods: A total of 80 players, aged 18 to 30 years, played four types of video games; Ru...
To study the effect of different levels of peppermint (Mentha piperita) plant powder, on immune system of broilers under heat stress condition, 192 one-day old chickens (Ross, 308) were randomly allocated to 4 dietary treatments with 4 replicates of 12 chicks each, using a completely randomized design. The four groups were characterized by a basal diet (control), basal diet supplemented with 1 ...
it has been recognized that acute and chronic stress has an impact on the immune system. acute stress may have a stimulating effect on the immune system, while in the case of chronic stress specially depression, the immune system could be down-regulated. however, an association between depression and a higher number of circulating white blood cells with increased activity has been reported. ele...
in order to study the sensitivity of vegetative growth to water deficit stress of a late-maturing peach (prunus persica l. cv. elberta) under orchard conditions, an experiment was conducted as randomized complete-block design with three treatments and four repetitions in shahdiran commercial orchard in mashhad during 2011. three irrigation treatments including 360 (low stress), 180 (moderate st...
