    Abstract: The problem of selecting a suitable safety factor for industrial products, and especially for a design proposal is reviewed. Products are mainly introduced to provide a certain profit or turnover in terms of resources enhancement. However, any proposed product will somehow drain natural resources whether it operates properly or erroneously. A compr... Show More

    Abstract: In this work, the computational fluid dynamics is used to model a micro torch. This is to investigate the effect of wall conductivity for different operating conditions on combustion characteristics as well as flame stability. The effect of convective heat transfer coefficient on the flame stability, out of the burner, is also studied. The results ... Show More

    Abstract: Zingin watershed is one of the most erosion-prone watersheds in the highlands of Ethiopia which received little attention. This study was, therefore, carried out to spatially predict the soil loss rate of the watershed with a Geographic Information System (GIS) and Remote Sensing (RS). Revised Universal Soil Loss Equation (RUSLE) adapted to Ethiopi... Show More
