Membrane filtration is a vital industrial process, with applications including air purification and blood filtration. In this paper, we study the optimal design for concertinaed membrane composed of angled porous membranes dead-ends. We examine how filter performance depends on angle, position, thickness, permeance membrane, through combination numerical asymptotic approaches, latter in limit s...
The present study was conducted to find the effect of three heavy metals, Ag, Hg and Pb on the expression level of a gene encoding plasma membrane H+-ATPase in Aeluropus littoralis. The experiment was laid out in a completely random design with three replications. The expression of the main gene was normalized to the expression of the housekeeping gene actin. Two 259 and 187 bp fragments were a...
The time-lag method, using a gas permeation experiment, is currently the most popular method for determining the membrane properties: diffusivity coefcient and permeability coefcient, and from which the solubility coefcient can be calculated. In this investigation, the impact of systematic, random (noise), resolution and extrapolation errors associated with gas permeatio...
