In this research the simulation of an air independent Proton Exchange Membrane Fuel Cell (PEMFC) propulsion system was taken into consideration. The system consists of several parts including PEM fuel cell stack, metal hydride and liquid oxygen (LOX) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. The heat recovery...

thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Background and purpose: Nitrous oxide (N2O) is an anesthetic widely used in operating rooms. Chronic exposure to N2O causes decrease in mental performance, peripheral neuropathy, and polyneuropathy. The aim of this study was to compare neurological complications caused by N2O exposure between operating room staff and other hospital staff. Materials and methods: In this multicenter cohort study...
