Soil Erosion and Sediment Export in Berta Watershed Using GIS and USLE Model in Central Rift Valley Basin, Ethiopia: Implications for Sustainable Natural Resources Management
Abstract: Soil erosion and sedimentation of lake due to runoff is a major problem in Southern Ethiopia. Berta watershed is one of the watersheds in Rift valley Basin, contributing runoff to small Abaya (Tuffa) lake. However, no studies have been conducted on soil erosion and sediment yield from the entire watershed. Therefore, an updated Universal Soil Loss Model and Geographic Information System have been used to start the current study, which …

A New Method of Juice Concentration using a Hydrogen Bubbles Photoelectroflotation Process Powered by Solar
Abstract: Currently, juice concentrates are produced by extracting water from freshly squeezed juice. To extract water from freshly squeezed juice, one of the following methods is used: evaporation, freezing of water, or the use of diaphragms. When evaporating, freshly squeezed juice is heated in a vacuum in special trays, but not to the boiling point, since boiling the juice will destroy all its useful substances. The mass, obtained after evaporation is …

Heavy Ion Radiation Damage Track Studies in SSNTDs (Polymers, Glasses and Minerals) and Single Activation Energy Model
Abstract: My training in Marie and Pierre Curie University, Paris for the identification of relativistic particle tracks in nuclear emulsions came handy for shifting to Heavy ion track studies in solid state nuclear track detectors (SSNTDs). Track formation mechanism in both may be different, but the basic nature of phenomenon by which the tracks are produced remains essentially the same. All charged particles produce ionisation of the medium and lose energy …

Analysis of Flow around Conical, Ogive Nose Cones in Hypersonic Space Shuttle
Abstract: Hypersonic flow is a high Mach number regime used to distinguish flow fields, phenomena and problems appearing at flight speed far greater than the speed of sound. In high speed flows shock waves are formed during the flow. High speed flow have high energy level, thus dissipate large amount of heat, resulting in high temperatures, which may even burn the surface. The nose cone should be built with an outer …
