DETERMINATION OF DIFFUSION COEFFICIENTS OF FOOD ADDITIVES IN DIFFERENT MEDIA AT 25˚C
(University of Eldoret, 2013)Food additives play a vital role in today’s bountiful and nutritious food supply and their transportation in water is a diffusion process governed by Fickian diffusion laws. The study looks into the rate of diffusion of ... -
THEORETICAL DETERMINATION OF SPECIFIC HEAT AND CRITICAL TEMPERATURE OF HIGH-TC CUPRATE SUPERCONDUCTORS BASED ON INTRALAYER AND INTERLAYER INTERACTIONS
(University of Eldoret, 2013)The role of attractive interlayer and intralayer interactions in layered high-Tc Cuprate superconductors was investigated using a two-layer Hamiltonian. The Hamiltonian was formulated and diagonalized using Bogoliubov ... -
AN INVESTIGATION OF EFFECTS OF BOUNDARY LAYER THICKNESS ON A THIN FILM OF LIQUID FLOW DOWN AN INCLINED PLANE
(University of Eldoret, 2013)The motion of fluid substances can be described by the Navier-Stokes equations. These equations arise from the application of Newton's second Law of motion to a fluid. In this study, Navier-Stokes equations in two ... -
