abstract a significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. this research presents a straightforward approach for processing output of the hec-ras hydraulic model, to enable two- and three dimensional flo...

Introduction: Alzheimer’s disease is a progressive neurodegenerative disorder, characterized by impairment of memory and changes in behavior and personality. Recent evidence suggests that mitochondrial channels play important roles in memory disorders. Accordingly, the biophysical properties of a single potassium channel were investigated in the brain mitochondrial inner membrane of rat with...

Numerical analysis is performed to investigate transport phenomena in channel flows under uniform heating from both side-walls. Emphasis is placed on an effect of heat flux ratio from both sides on the velocity and thermal fields. The twoequation heat-transfer model is employed to determine thermal eddy diffusivity. It is found that (i) under strong heating from both walls, laminarization, i.e....

In this paper, a three-dimensional, single-phase proton-exchange membrane fuel cell (PEMFC) is studied numerically. Finite volume method was used for solving the governing equations and, consequently, the numerical results were validated by comparing them with experimental data, which showed good agreement. The main objective of this work is to investigate the effect of a novel gas channel shap...
