‎in this paper‎, ‎we have investigated the chaotic behavior of thermal convection in couple stress liquid saturated porous layer subject to gravity‎, ‎heated from below and cooled from above‎, ‎based on theory of dynamical system‎. ‎a low dimensional lorenz‎- ‎like model is obtained by using galerkin-truncation approximation‎. ‎we found that there is proportional relation between scaled couple ...

Microdialysis was used to measure the effect of benzodiazepines (BDZs) on basal levels and on stress-induced increases of 5 -hydroxytryptamine (5 -HT), 5 - hydroxyind oleacetic acid (5 -HIAA) , noradrenaline (NA), and dihydroxyphenylacetic acid (DOP AC). The stressors used were a 5 min tail pinch or a 10 min period of restraint. A subcutaneous injection of 5 mg/kg diazepam decreased basal ...

objective(s): stress induces many homeostatic aberrations which are followed by lifelong allostatic responses. epilepsy is developed or influenced by different environmental factors, i.e. prenatal stress which makes many contradictory developmental changes in seizure threshold and intensity. we investigated the potential seizure response of the rat offspring to prenatal stress; the stress which...

Adolescence is characterized by increased social stress due to changes in interpersonal relationships, but little is known about daily experiences of social stress. The aim of the present study was to examine daily life predictors of increases in social stress, how these increases affected adolescents' mood, and whether loneliness moderated these relations. The Experience Sampling Method was us...
