(University of Eldoret, 2016)Coffee, tea and soya, are widely consumed beverages in Eldoret town. However there is scanty information available on the level of components of these products in the market. A study was conducted to determine the polyphenol ... -
Investigation of Selected Heavy Metal Ions in Irrigation Water, Soil and Managu (Solanum Nigrum) from Homahills, Homabay County, Kenya
(Journal of Health and Environmental Research, 2019)Levels of selected heavy metals of Mn, Cd, Pb, Zn, Fe and Co were evaluated in irrigation water, soil and managu (Solanum Nigrum) from Homahills, Homabay County, Kenya. The samples were collected purposively and randomly ... -
DIFFUSION OF ASPIRIN-(ACETYLSALICYLIC ACID) BASED DRUGSIN SODIUM HYDROXIDE SOLUTION AT 25C
(University of Eldoret, 2014)Diffusion is a macroscopic motion of components of a system that arises from concentration difference and plays a vital role in drug migration in the bodygoverned by Fickian diffusion laws. This project considers effective ... -
SOIL FERTILITY AMENDEMENT USING MOLASSES WASTEWATER AND PIGWASTE AND THEIR INFLUENCE ON SOIL CHARACTERISTICS AND YIELD OF COWPEAS (Vigna unguiculata)
(University of Eldoret, 2014)Soil fertility is the number-one natural resource in Africa. However, due to high soil acidity and low fertility, food production has declined over the last decade. A case in point is in Uasin Gishu County, where farmers ... -
KINETICS OF METAL POLLUTANTS BIOSORPTION IN LAKE VICTORIA AND ITS ENVIRONS USING MORINGA OLEIFERA SEED POWDER
(University of Eldoret, 2016)In the last three decades attention has been paid to environmental management caused by hazardous materials such as heavy metals whose levels have risen due to increased anthropogenic activities. One of the techniques used ... -
