Effects of Zeolite X on Dissipation of Hexazinone from Agricultural Waste Waters in Western Kenya
(2013-10)Dissipation of hexazinone in Zeolite X treated wastewater followed pseudo first-order kinetics giving a calculated half-life of 41 days compared to a half-life of 144 days in untreated wastewater. The herbicide degraded ... -
Natural Convection in a Rectangular Enclosure with Colliding Boundary Layers
(Journal of Applied Mathematics & Bioinformatics, 2014)The movement of the fluid in natural convection results from the buoyancy forces imposed on the fluid when its density in the proximity of the heat transfer surface is decreased as a result of the heating process. The ... -
Effects of Temperature on Ilmenite During Concentration of Iron in Laterites Using Charcoal and Separation using Magnetic Separation
(International Journal of Scientific Engineering and Technology, 2014)Effect of temperature on ilmenite minerals found in laterites has been investigated. It was found that during reduction of iron minerals in laterites to magnetite using charcoal at temperatures of about 500-700oC, ... -
