Influence of polymer solution concentration and media permeability on the residual resistance factor
Purpose. Determination of the required concentration polymer solution, providing maximum well insulation effect, depending on filtration characteristics medium. Methodology. The research was conducted by experimental method using methodology planning experiment. theory rational used varying two variables five levels. Media permeability and solution were as variables. Methods mathematical statis...
Surface cracks in butt-welded joints usually occur places with increased stress concentrations. The concentration factor (SCF) can be calculated using an empirical equation, five geometric parameters of a joint (thickness the base material, toe radius, weld angle, width, and reinforcement height). However, industrial environment, it is impractical sometimes even impossible to measure all suffic...
Toll-like receptors (TLRs) activate antimicrobial gene expression in response to detection of specific bacterial products. Relatively little is known about TLR5, the only TLR thought to be preferentially expressed by epithelial cells, beyond that it confers activation of the transcription factor NF-kappaB in a MyD-88 dependent manner in response to flagellin. Because TLRs, in general, are also ...
