Comparative assessment of total Phenolic content in selected medicinal plants
(2008)This study was to compare the total phenolic (TP) content in extracts from eleven plant materials collected at different geographical locations in Kenya, Nigeria, and USA. These plants have been selected because the majority ... -
Long-term effects of tillage, sub-soiling, and profile strata on properties of a Vitric Andosol in the Kenyan highlands
(2008)Tillage alters the structure and composition of soil aggregates affecting infiltration rate (IR) and hydraulic conductivity (K). This study investigated the long-term effects of conventional, minimum, and no-tillage with ... -
Impregnated dry Filter paper as an Alternative medium for Transporting Diarrhoeal Stool Samples
(2008)Diarrhoea due to bacterial infections is a major cause of morbidity and mortality both in children and adults and hence lowers economic activity especially in developing countries. This is especially important in areas ... -
Kenyan Nurses’ involvement in managing hospitalized diabetic patients
