Methods to derive macroscopic transport equations for rarefied gases from the Boltzmann equations are presented. Featured methods include the Chapman-Enskog expansion, Grad’s moment method, and the author’s order of magnitude method. The resulting macroscopic equations are compared and discussed by means of simple problems, including linear stability, shock wave structures, and Couette flow.
Two specific signals for regulating liver regeneration were found after 70% partial hepatectomy (PH) in rats. The first finding was a sustained increasing signal of intracellular Ca2+ ([Ca2+]i) in hepatocytes, consisting of two successive peaks with the first narrow peak at 1 hour and the second broad peak increasing by day 3 and then returning to normal by day 4. The second finding was an abno...
Four different types of macroscopic models developed for the vibration-chemistry coupling in nonequilibrium flows for re-entry applications are presented. First, using an approach based on nonequilibrium thermodynamics, global rate coefficients of dissociation of N2 and O2 under parent molecular or atomic impact and backward molecular recombination are determined. Then a Two-Level Distribution ...
This study aims to examine differences in the number of bacterial colonies after skin preparation using a combination 70% alcohol and 4% chlorhexidine gluconate with 10% povidone-iodine. used quasi-experimental method pre-post test design. The results showed decrease by 99.84% group gluconate, 99.77% povidone-iodine groups. While difference between two groups, there was no significant p-value 0...
