USE OF CONSTRUCTED WETLANDS AND SAND FILTERS TO IMPROVE THE QUALITY OF WATER IN BOMACHOGE-BORABU, KENYA
(University of Eldoret, 2016)Degradation of aquatic ecosystems resulting from pollution, poor waste disposal management practices and inadequate knowledge is of concern. Water sources in developing countries are abundantly contaminated with animal and ... -
PHYTOCHEMICAL COMPOSITION AND ANTIBACTERIAL EFFECT OF Sida cuneifolia Vollesen ON SELECTED PATHOGENIC BACTERIA
(University of Eldoret, 2016)During the last decade, the use of traditional medicine has escalated globally. With the increase in antibiotic resistance, there is need for increased search for new plants that possess antimicrobial properties. Sida ... -
SYNTHESIS AND CHARACTERIZATION OF NOVEL TBAF-PROMOTED DESILYLATION OF FLUOROGENIC 3-CYANO-7-HYDROXY-4-METHYLCOUMARIN DERIVATIVES AS POTENTIAL RAPID FLUORIDE DETECTORS IN POTABLE WATER
(University of Eldoret, 2021)Over the years, Fluoride has been identified as a contaminant of great global concern on drinking water safety. The need to prevent the population from consuming higher fluoride content in water lies in fluoride sensing. ... -
CRYSTALLIZATION OF HELIUM-3 AND NEUTRON MATTER FERMIONS IN CONDENSED MATTER PHYSICS
(University of Eldoret, 2017)In this Thesis crystallization of a hard-sphere assembly of fermions with densities ranging from low to high values has been theoretically investigated, the fermions are very close to each other, and the interaction between ... -
USE OF TAYLOR’S SERIES EXPANSION IN DEVELOPING FINITE DIFFERENCE METHODS FOR SOLVING THE WAVE EQUATION
(University of Eldoret, 2021)Hyperbolic partial differential equations (PDEs) are used to model physical phenomena such as wave propagation. Among the simplest hyperbolic equations are the 1-D advection equation which is a first order PDE and the 1-D ... -
