This paper aims to study the permeability of High-Performance Concrete containing natural pozzolan and reinforced with fibers in high concentration sodium chloride solution. Optimized finely ground was employed as 6% partial substitution cement. Polypropylene 6 mm 12 lengths were introduced individually for a volume fraction 0.1% 0.15% respectively. Then, combination total fiber content 0.25%. ...

Previous animal and human studies have shown protective effects of Ca on the resistance to enteropathogenic infections. Most interventions were performed with calcium phosphate and little is known about the protective effect of other dietary sources of Ca. Therefore, we investigated the efficacy of several Ca salts to enhance intestinal resistance to Salmonella enteritidis infection. Rats (n 7-...

Water and salt transport properties were determined in a family of sulfonated pentablock copolymers to characterize their potential as chlorine-tolerant desalination membrane materials. The degree of sulfonation, block molecular weight, and casting conditions can be independently varied to tune the transport properties of these materials. Data for water uptake, water permeability, salt permeabi...

Abstract The world today has started facing bigger problems related to the concrete industry, especially with becoming most extensively used construction material in world. At a time like this, where more eco-friendly substitutions are stringent, it calls for comprehensive approach producing recycled from aggregates (RCA). This study is an extension previous studies involving composite utilizat...

Sodium taurocholate is able to produce a decrease in permeability and to antagonize NaCl. This confirms the hypothesis that antagonistic relations can be predicted from studies on the permeability of pure substances.

An in vitro test for the development of corneal opacity in response ocular irritants was first proposed by Muir (1984). This test required the clamping of a bovine cornea between two chambers filled with physiologic saline and measuring the transmittance of white light through the cornea using the voltage output of a photocell. This was followed by exposure of the epithelial surface of the corn...
