Challenging space missions include those at very low altitudes, where the atmosphere is source of aerodynamic drag on spacecraft. To extend lifetime such missions, an efficient propulsion system required. One solution Atmosphere-Breathing Electric Propulsion (ABEP) that collects atmospheric particles to be used as propellant for electric thruster. The would minimize requirement limited availabi...

introduction: to study the teratogenicity of diazepam intake during pregnancy andits effects on visual system development. materials and methods: about 30 virgin rats of known age and weight were used. after pregnancy, they were divided in three groups: 1) control group: 10 rats (injection daily with destiled water). 2) first experimental group: 10 rats (injection daily with destiled water and ...

The Electrical Submersible Pumping (ESP) system is one of the most commonly used artificial lift methods in petroleum industry and recent breakthrough this enclosed a capsule positioned on seabed skid. As it technology, with only small amount equipment currently operation, there clear need for greater understanding flow within geometry objective perfecting design promising submarine boosting sy...

Introduction: The brain glutamate neurotransmitter system and its NMDA receptors in the nucleus accumbens play an important role in the incidence of the phenomena of sensitivity and addiction. The present study examined the inhibitory effect of glutamate NMDA receptors in the nucleus accumbens in response to chronic stress. Methods: After the unilateral and bilateral cannula placement in the ...

Ghrelin has been attributed various physiological processes including food intake and reward regulation, through activation of the mesolimbic dopamine system. Reward modulation involves the mesolimbic dopamine system, consisting of the ventral tegmental area (VTA) dopamine neurons targeting nucleus accumbens (NAc), a system that ghrelin activates through VTA-dependent mechanisms. In the first s...
