In this paper, a numerical scheme is proposed for the multi-fluid compressible flows. This method is applied to the problem of underwater explosion. The proposed scheme is basically the extension of Godunov method in gas dynamic problems to the multifluid environments and is second-order accurate in space. In this method, also, the problem of artificial mixing of two different phases on Euleria...

This study was conducted with the purpose of examining Persian speakers’ article acquisition and use with reference to Ionin, Ko and Wexler’s (2004) model, which is based on the prediction of Fluctuation Hypothesis (FH) that EFL learners of [-article] languages, like Persian, make erroneous article use in [+definite, -specific] and [-definite, +specific] contexts. From among the students of an ...

Nowadays, because of the need to decrease fuel consumption and greenhouse gas emissions and also their capability of exchanging power with the grid and regulating the frequency and voltage of the grid at different times of the day, electric vehicles are used more than before all across the world. It is highly important to pay attention to the efficiency, and decrease in the weight and volume of...

Exposure to carbon monoxide (CO) is the leading cause of death by poisoning in industrialized countries. It accounts for hundreds of accidental deaths and thousands of intentional deaths annually in the United States. CO is a colorless, odorless gas that is easily absorbed through the lungs when inhaled. It competes with oxygen for binding to hemoglobin, but because hemoglobin has an affinity f...

Last generation of force-fields are raising expectations on the quality of molecular dynamics (MD) simulations of DNA, as well as to the belief that theoretical models can substitute experimental ones in several cases. However these claims are based on limited benchmarks, where MD simulations have shown the ability to reproduce already existing 'experimental models', which in turn, have an uncl...
