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...

analogy and how to treat it is among the earliest issues in the jurisprudence and principles of legal schools. meanwhile, although in shī‘ism the universal approach in this respect has since long ago been a negative one and it still continues to be so, the important issue that has to be taken into further consideration and more deeply contemplated on despite the theological viewpoints of the ju...

Nano structures such as nanowires, nanobeams and nanoplates have been investigated widely for their innovative properties. In this paper the buckling of nanowires surrounded in a Winkler - Pasternak elastic medium has been examined based on the nonlocal Euler-Bernoully model with considering the surface effects. In the following a parametric study that explores the influence of numerous physica...

The aim of this paper is to find connections between the digital game Sunless Sea (Failbetter Games, 2015) and Joseph Conrad’s novels, particularly ones touching on subject sea voyage. an exploration role-playing which focuses topics sailors’ loneliness, dual nature sea, above all, player’s inevitable failure. These tropes are shown not only in narrative structure game, but also its mechanics d...
