(University of Eldoret, 2013)Traditional medicines play an important role in the management of common fever associated with malarial symptoms, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully ... -
INVESTIGATION OF POLLUTANT LEVELS AND EFFICIENCY OF HEAVY METAL REMOVAL USING BROWN ALGAE (Sargassum sp) BIOSORBENT: A CASE STUDY OF MIGORI RIVER, KENYA
(University of Eldoret, 2013)ABSTRACT An increase in population initiating rapid industrialization has been found to consequently increase the effluents and domestic wastewater into the aquatic system. This has resulted in heavy metal pollution which ... -
EFFECT OF LIMING ON LEVELS OF POLLUTANT HEAVY METALS IN SOILS AND THEIR UPTAKE BY MAIZE IN UASIN GISHU AND TRANS-NZOIA COUNTIES, KENYA
(University of Eldoret, 2013)Soil contaminated with heavy metals from agricultural and industrial sources leads to unhealthy food. The metals enter the food chain and are consumed by humans. Phosphate fertilizers too contain undetermined amounts of ... -
SYNTHESIS OF A PHENYLETHYLTHIOUREA DERIVATIVE AS A POTENTIAL NON-NUCLEOSIDE INHIBITOR OF HIV-1 REVERSE TRANSCRIPTASE
(University of Eldoret, 2013)The emergence of resistant strains of HIV-1 towards existing drugs has prompted a search for new compounds with good antiviral activity and favourable toxicological profile. This work reports the synthesis of a PETT ... -
SPATIAL AND TEMPORAL VARIATIONS IN PHYSICO-CHEMICAL PARAMETERS, NUTRIENTS AND HEAVY METALS ALONG A GRADIENT OF ANTHROPOGENIC ACTIVITIES WITHIN KAPSABET RIVER, KENYA
(University of Eldoret, 2013)Increased human activities have led to water pollution, especially metals and nutrients. Therefore, prudent management of aquatic environments require information on their quality status that can be estimated by monitoring ... -
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 ... -
ab-initio STUDIES OF MAGNESIUM HYDRIDE AND LITHIUM HYDRIDE FOR HYDROGEN STORAGE APPLICATIONS: A DENSITY FUNCTIONAL THEORY STUDY
(University of Eldoret, 2013)Due to the imminent exhaustion of fossil fuels, related pollution and high cost involved in conventional sources of energy, a search for renewable, environmentally friendly, cheaper and more e cient energy sources has ... -
POLLUTANT LEVELS IN WASTE WATER FROM TANNERY EFFLUENT: A CASE STUDY OF NAKURU TANNERS, KENYA
(University of Eldoret, 2013)Wastewater from leather processing industries is very complex and leads to water pollution if discharged before treatment, especially due to its high organic loading and chromium content. Over the past years, Nakuru Tanners ... -
DETERMINATION OF SELECTED HEAVY METALS POLLUTANTS AND PHYSIO-CHEMICAL PARAMETERS IN SEDIMENTS AND WATER: A CASE STUDY OF RIVER ATHI MACHAKOS COUNTY
(University of Eldoret, 2013)The study set out to evaluate the effect of industrial activities by analyzing selected heavy metals and physicochemical parameters of water. Chemical survey was conducted in 9 selected sites (potential polluting sites) ... -
