The question of whether mesospheric OH(υ) rotational population distributions are in equilibrium with the local kinetic temperature has been debated over several decades. Despite several indications for the existence of non-equilibrium effects, the general consensus has been that emissions originating from low rotational levels are thermalized. Sky spectra simultaneously observing several vibra...

In this study, the behavior of a subject consisting of a cylinder with 4 plates perpendicular to it with a rotational degree of freedom under airflow both through the numerical approach, known as improved discrete vortex and experimental approach were investigated. The experimental and numerical results have shown that oscillating regime occurs in low velocity and length. This movement is vibra...

Rotational behavior induced by electrical stimulation of ascending dopamine neurons is used as a behavioral model to investigate gender and hormonal influences on extra-h)pothalamic doparmne systems. Steroid hormones influence the metabolism of many dopaminergic drugs, and therefore ihis approach avoids the complications inherent in drug-induced behavior models of dopamine activity. We found th...

background and objective: parkinson's disease (pd) is an age-related neurodegenerative disease with selective damage of dopaminergic neurons of the mesencephalon. l-dihydroxyphenylamine (l-dopa) therapy is currently the gold standard maneuver for pd. due to the protective, anti-inflammatory, and antioxidant effect of sesamin, this study was undertaken to assess dose-dependent effect of this age...

Classical estrogen receptor-signaling mechanisms involve estradiol binding to intracellular nuclear receptors [estrogen receptor-alpha (ERalpha) and estrogen receptor-beta (ERbeta)] to promote changes in protein expression. Estradiol can also exert effects within seconds to minutes, however, a timescale incongruent with genomic signaling. In the brain, estradiol rapidly potentiates stimulated d...

this study was aimed at evaluating the flow behavior characteristics of yogurt enriched with fish oil (fo) microcapsules prepared by complex coacervation method. fo was microencapsulated in gelatin-acacia gum coacervates. then, the microcapsules were dried, and yogurt was produced from the milk enriched with microcapsules powder. rheological characteristics (as measured using a rotational visco...

the rotational friction dampers can be improved the seismic behavior of the steel structures, and they can be reduced the internal forces in the bracing members, columns and the other structural members. in this research, a simple method for modeling and analysis of braced frames equipped by these dampers is proposed. the proposed model describes seismic behavior of dampers very well and it is ...

Optical heterodyne-detected optical Kerr effect (OHD-OKE) experiments and pulsed field-gradient spin-echo NMR (PFGSE-NMR) experiments were performed to measure the rotational and translational diffusion constants of a polyether, tetraethylene glycol dimethyl ether (TEGDE), in binary mixtures with water over concentrations ranging from pure TEGDE to approaching infinite dilution. In addition, hy...
