Spatial and Inter Annual Patterns of the Surface Temperatures Over East Africa
(University of Nairobi, 1998)In this study inter-annual patterns of the surface temperature are investigated in order to determine the major climatic fluctuations within the period 1943-1983. The spatial similarities in the observed fluctuation pattern ... -
Dietary composition of wildebeest (Connochaetes taurinus) kongoni (Alcephalus buselaphus) and cattle (Bos indicus), grazing on a common ranch in south-central Kenya
(University of Nairobi,, 2003-03-14)This paper gives the results of a study conducted at Game Ranching Ltd, situated at the Athi Kapiti Plains, Kenya, to determine the dietary composition of cattle (Bos indicus L), kongoni (Alcephalus buselaphus Pallas) and ... -
A Surface Regression Approach For Estimation Of Genetic And Environmental Trends Under Widely Varying Meteorological Conditions Between Years
(University of Nairobi, 2002-04)Under tropical conditions meteorological variations may be a major source of nuisance in the estimation of genetic and environmental progress achieved. In this paper an approach is presented to incorporate polynomial ... -
Enhancing Soil Water Content for Increased Food Production in Semi-Arid Areas of Kenya Results From an On-Farm Trial in Mwala District, Kenya
(University of Nairobi, 2014-03)Soil water conservation through tillage is one of the appr opriate ways of addressing soil moisture deficit in rainfed agriculture. This study evaluated the effects of tillage practices on soil moisture conservation and ... -

Application of the Ems-Wrf Model in Dekadal Rainfall Prediction over the GHA Region
(University of Nairobi, 2014)The IGAD Climate Prediction and Applications Centre exists to monitor and predict the patterns of rainfall over the greater Horn of Africa region, and provide early-warning products and information, particularly concerning ... -
Flood Forecasting Over Lower Nzoia Sub-basin In Kenya
(University of Nairobi, 2014)Real time flood forecasting is one of the most effective non- structural measures for flood management. In this study, Ensemble Kalman Filter (EnKF) is used with Probability Distributed Moisture model (PDM) to forecast ... -
Use of remote sensing techniques for the exploration of groundwater: a case study of Voi divison Taita Taveta district.
(University of Nairobi,, 2005-07)This dissertation applies remote sensing techniques in groundwater exploration. Remote sensing techniques provide efficient real time methods for analysis of hydrologic issues and tools for water use planning and modelling. ... -

(University of Nairobi, 2014-06)The influence of the El - Nino Southern Oscillation (ENSO) evolution phases and monthly precipitation over the 47 counties in Kenya i s analysed using Pearson product moment correlation analysis. Anomalies of ... -
The Shang Ring device for adult male circumcision: a proof of concept study in Kenya
(University of Nairobi,, 2011)Objective: To assess safety, preliminary efficacy, and acceptability of the Shang Ring, a novel disposable device for adult male circumcision in Kenya. Methods: Forty HIV-negative men were recruited in Homa Bay, Kenya. ... -
Spatial Interpolation Of Daily Rainfall Stochastic Generation Parameters Over East Africa.
(University of Nairobi, 2014)Downscaling seasonal rainfall predictions to daily time-scale, for crop yield simulation for instance, can be performed using stochastic generators (SGs). The spatial interpolation of the SG parameters is required to ... -
Lignocellulolytic Activities Of Crude Gut Extracts Of Marine Woodborers Dicyathifer Mannii And Sphaeroma Terebrans
(University of Nairobi, 2006)Marine woodborers have a close association with tropical mangrove plants whereby they voraciously consume lignocellulose and play a role in nutrient cycling. T hey represent a rich source of potential lignocellulo ... -
Adsorption of Congo Red Dye from Aqueous Solutions Using Roots of< i> Eichhornia Crassipes</i>: Kinetic and Equilibrium Studies
(University of Nairobi, 2014)Adsorption of Congo red (CR) from aqueous solution using dried roots of Eichhornia crassipes was studied. Batch experiments were carried out for sorption kinetics and isotherms. Experimental results obtained showed that ... -
Determination of the Effects of Nutrient sources on Enhancement of Crop Tolerance to Bean Root Rot and Bean Stem Maggot in Western Kenya
(University of Nairobi, 1999)Field bean phaseolus vulgaris tolerance to root rot (BRR) and bean stem maggot (BSM) is enhanced by improvement of soil nutrients. Organic and inorganic sources of soil nutrients were evaluated in this study to determine ... -
Induction Of Potent And Long-lived Antibody And Cellular Immune Responses In The Genitorectal Mucosa Could Be The Critical Determinant Of HIV Vaccine Efficacy
(University of Nairobi, 2014-05)The field of HIV prevention has indeed progressed in leaps and bounds, but with major limitations of the current prevention and treatment options, the world remains desperate for an HIV vaccine. Sadly, this continues to ... -
Functional Proportions Of Primate Lumbar Vertebral Bodies
(University of Nairobi, 1975-01)The comparison of certain proportions of lumbar vertebral bodies and of the lumbar column as a whole between a range of primate and non-primate mammals suggests that the relatively high robusticity of the lumbar column in ... -
Plant Dispersal by Hares (Lepus Capensis L.) in Kenya
