this work is aimed to evaluate the role of nanoclay in the protective performance of an eco-friendly silane sol-gel layer applied on mild steel substrate in 0.1m sodium chloride solution. at the first step, the effect of ph of the silane solution, consisting of a mixture of γ-glycidoxypropiltrimethoxysilane and methyltriethoxysilane and tetraethoxysilane, on the coating performance was evaluate...

This research studies the effects of viewing a positive or a negative (violent) film clip on the psychophysiological responses to social exclusion. While previous research has found impressive behavioral overlap between social exclusion and violent media, these two stimuli have not been studied together. Subjects were exposed to either a positive or a negative film prior to being ostracized by ...

A protective coating has been applied onto the phosphated panels using cathodic electrocoating in two different dry film thickness namely 8µm and 20µm. The corrosion resistance of cathodic electrocoatings has been studied using AC/DC/AC method. Twelve cycles of AC/DC/AC test were carried out on each sample which the DC voltage of the first 6 cycles were -4 V VS. Ag/AgCl @ 20 minutes followed by...

Using a multifactorial experiment of the plan N = 2(4), influence components air pollution in livestock buildings on moisture absorption film D-11A plastisol mastic was studied by gravimetric method. The corresponding dependence equations are obtained, which show more aggressive effect hydrogen sulfide and sulfur dioxide protective film.

EDITORIAL The penetration of drugs in the eye after topical administration is one of the most interesting challenges the pharmaceutical science is facing. The objective of the scientist is to penetrate the protective barriers of the eye without damaging ocular structures. In contrast with other epithelia, the epithelium of the ocular surface is not prepared for absorption which means that the t...
