Evolution of the cluster population has been recognized as a powerful cosmological tool. While the pre-sent–day abundance of X-ray clusters is degenerate in σ 8 , n and Ω 0 , Oukbir and Blanchard (1992, 1997) have pointed out that the number density evolution of X-ray clusters with redshift can be used to determine Ω 0. Here, we clarify the origin of this statement by identifying those paramete...

The purpose of this study was to detect staphylococcal classical enterotoxins (SEs) in processed beef from Kingdom of Saudi Arabia (KSA) and Egypt. 1 Department of Food Hy...

In this study, the environmental characteristics of Al-Hillah River were studied using geoinformatics applications, which is one geospatial techniques (GST). Applying methodology, a geographic information system was developed, and it supplied with laboratory data for physical chemical properties 16 parameters 2021. These linked to their spatial locations, radar imagery Digital Elevation Model (...
