Previous studies have shown that N-methyl-D-aspartate (NMDA) receptor activation results in production of reactive oxygen species (ROS) and activation of extracellular signal-regulated kinase (ERK) in hippocampal area CA1. In addition, application of ROS to hippocampal slices has been shown to result in activation of ERK in area CA1. To determine whether these events were linked causally, we in...

prut river is very important for sustaining the biodiversity and economical activities in its area for romania, ukraine and republic of moldova. anthropogenic activities are present everywhere especially near a big water flow because they need a close water resource. the major problems remain the impact and a possible risk produced as a negative result in these activities (agriculture close to ...

study area is located in west of iran with relatively rough topography. lithologic units in the region belong from jurassic and cretaccous till recent era. the study area of the alvand mountain region is related to the tectonic zone of the sanandaj-sirjan region and the area dominant neo-tectonic regime appears to be compressional-extensional type. one of the identification tools to find out th...

Determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. In this paper, the maximum power of the MGT-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. In a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required sta...
