(University of Nairobi, 1993)In a survey of plant parasitic nematodes on passion fruit in Kenya 10 genera of nematodes were discovered. Of these, 8 were identified to species level, two of which attempts were made to determine the existence of races. ... -
Copper Indium Diselenide (CIS) Based Solar Cells: Effect Of CIS Preparation Conditions And Thickness On Performance
(University of NairobiFaculty of Science, 1999-09)The effect of CulnSe, thin film preparation conditions and thickness on CuInSe2 based solar cells has been investigated. Prior to CuInSe2 thin films and device fabrication, metallic Cu and In resistivity changes with ... -
Optimum Age-specific Harvesting Policy For A Population Growing According To The Leslie Matrix Model
(University of NairobiDepartment of Mathematics, 1997-11)Under favorable conditions, natural animal population has a tendency to increase in numbers. It is, however, possible to remove some animals and still maintain a constant population size. This type of removal is known ... -

(Department of Geology, University of Nairobi, 2001)The aim of this study was to investigate the detailed geology, the geochemistry and the mineralogy associated with the mafic and the ultramafic intrusives of the Mozambique Belt, eastern Kenya. To achieve this, a detailed ... -
Influence of major competitors on the abundance and distribution of cheetahs in Maasai Mara national reserve
(2006)Over the years the cheetah population in Masai Mara National Reserve has declined and this has been attributed to several factors. Key among them is the influence of other predators like lions. leopards and hyenas, who ... -
Mechanisms Of Leishmania Uptake And Transmission By Phlebotomine Sand Flies (diptera: Psychodidae
(University of NairobiFaculty of Science, 1995)Leishmania parasites undergo cyclical development in their vector sand fly through various stages before they can be transmitted by bite. Sand fly saliva aids in blood-feeding by modulating host-immune responses through ... -
