    Abstract: The purpose of this paper is to evaluate the effect of five different mixing rules on the calculated thermodynamic properties including vapor pressure, density and excess property of several binary mixtures. These properties are calculated by ISM (Ihm-Song-Mason) and PHS (Perturb Hard Sphere) equations of state (EOS). Also we use two interaction pa... Show More

    Abstract: China's energy demand is growing rapidly and large hydropower plants are becoming more common. This therefore has resulted in the building of many large concrete dams across the country. Significant dam cracking can have major environmental, economic and social consequences. Collapse of High concrete dam may cause serious harm to economic developme... Show More

    Abstract: In this study, the flux and energy of the helium ions beam produced by United Nations University/International Centre for Theoretical Physics Plasma Fusion Facility (UNU/ICTP PFF) and NX2 dense plasma focus devices, were studied when the pressure of gas changed by carrying out numerical experiments using Lee code. The results showed that the value ... Show More

    Abstract: Cow’s milk is considered as one of responsible food sources contamination with heavy metals. The objective of the study were to assess to content of selected heavy metals in fresh cow's milk and its associated human health risks in the food chain in Sudan. Fresh cow's milk samples were collected from two dairy of Merowe city-North Sudan by using At... Show More
