In an attempt to treat infection of mice skin, and investigate the antimicrobial effect of bacterial system (G-system) using essential oil and methanol extract of Tagetes patula flowers (Qadifah), several experiments were carried out.These extracts were investigated for the presence of some active secondary metabolites and their antimicrobial activity. Tagetes methanol flowers extract contained phenols, flavonoide, alkaloids, saponins, and terpenes.

Background: Semen preparation techniques were developed to separate motile sperm that are morphologically normal from seminal plasma to optimize successful assisted reproductive technology cycles which seem to be the most effective options in cases of a male factor infertility. Objective: The objective of the present study was to compare between outcomes of two sperm preparation techniques including:

Modeling of Cathodic Protection for Pipelines The corrosion of metallic structures buried in soils or in contact with soils has long been a serious engineering and economic problem. All over the world millions of kilometers of gas, water, oil pipelines, communication cables, power
