Leatherback turtles (Dermochelys coriacea) are exposed to many anthropogenic stressors, yet almost no data on stress physiology exist for this species. As a first step toward understanding the physiological responses of leatherback turtles to stress, and with the particular goal of assessment of the effect of capture, we quantified corticosterone (an adrenal stress hormone) and thyroxine (a reg...
The failure and repair of modules in an N-Modular Redundant (NMR) system are governed by a failure time distribution and repair time distribution, respectively. It is generally reasonable to assume that a module’s failure time distribution is a simple exponential distribution. However, it is not reasonable to assume that the repair time distribution is also exponential. Reliability models with ...
Acoustic Doppler velocity profiler (ADVP) measurements of instantaneous threedimensional velocity profiles over the entire turbulent boundary layer height, δ, of rough-bed open-channel flows at moderate Reynolds numbers show the presence of large scale coherent shear stress structures (called LC3S herein) in the zones of uniformly retarded streamwise momentum. LC3S events over streamwise distan...
Sympathetically mediated tachycardia and vasoconstriction maintain blood pressure during hypergravitational stress, thereby preventing gravitation-induced loss of consciousness. Norepinephrine transporter (NET) inhibition prevents neurally mediated (pre)syncope during gravitational stress imposed by head-up tilt testing. Thus it seems reasonable that NET inhibition could increase tolerance to h...
Drought is the most important problems that restrict cultivation of horticultural crops in arid and semi-arid regions and olive (Olea europaea L.) as an important fruit trees grows in these regions. In order to investigate the effect of cycocel treatment on some physioligical characteristics of two olive cultivars (Mary and Mission), under the condition of drought stress, a greenhouse experimen...
reduction of deleterious effects of salt stress using some plant bioregulators has been reported in different plant species. salicylic acid (sa) has been considered as a signaling molecule and it is known to ameliorate the oxidative damage caused by environmental stresses such as salt stress. the present study was conducted to investigate the effects of sa on different growth characteristics, p...
