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 ... -
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 ... -
The Influence Of El-niño Southern Oscillation On Seasonal Rainfall Over The 47 Counties Of Kenya
(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 ... -
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 ... -
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
(University of Nairobi,, 1970)Of 369 hares examined, 160 had a total of 810 disseminules of 17 plant species in their fur. The six commonest plants were Tragus berteronianus, Achyranthes aspera, Pupalia lappacea, Boerhavia repense, Harpachne schimperi, ... -
Distribution of repetitive DNA sequences in Vicia faba chromosomes
(University of Nairobi,, 1980)In situ hybridization of labelled complementary RNA transcribed from whole DNA to metaphase chromosomes indicates the presence of repetitive DNA in both euchromatin and heterochromatin of the Vicia faba genome. -
A comparison of student performance in two parallel physiology tests in multiple choice and short answer forms
(University of Nairobi,, 1978-07)Two parallel tests in physiology, one in multiple choice answer form and one in short answer form, were administered consecutively to a group of 104 students. The construction of the questions in the two papers and marking ... -

Costs Of Reproduction In A Long-lived Female Primate: Injury Risk And Wound Healing.
(University of Nairobi, 2014-07)Reproduction is a notoriously costly phase of life, exposing individuals to injury, infectious disease, and energetic tradeoffs. The strength of these costs should be influenced by life history strategies, and in long-lived ... -
Health and Natural Resources: The Extraction of Useful Chemicals from Plants and their Impact on Socio-Economic Development
(University of Nairobi, 2006)Poverty reduction strategies in developing countries are based on the need to develop and improve the quality of life of people. The successful strategies link wealth creating activities of adding value to local resources ... -
The Olduvai event at Olduvai Gorge
(University of Nairobi,, 1976)Palaeomagnetic polarity measurements from Beds I and II at Olduvai Gorge are described, and used to define the extent of the Olduvai event in the Olduvai Gorge section. The upper boundary of the event occurs very close to ... -
