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...
A significant increase in atmospheric radon concentration was observed in the area around the epicentre before and after the occurrence of the shallow inland earthquake in the northern Wakayama Prefecture on 5 July 2011 (Mj 5.5, depth 7 km) in Japan. The seismic activity in the sampling site was evaluated to identify that this earthquake was the largest near the sampling site during the observa...
The effects of chlorine and pH on the bactericidal activity of electrolyzed (EO) water were examined against Escherichia coli O157:H7 and Listeria monocytogenes. The residual chlorine concentration of EO water ranged from 0.1 to 5.0 mg/l, and the pH effect was examined at pH 3.0, 5.0, and 7.0. The bactericidal activity of EO water increased with residual chlorine concentration for both pathogen...
