Euler’s differential equation and the identification of the magnetic point‐pole and point‐dipole sources
(University of Nairobi, Department of Geology,, 1994)The concept of point‐pole and point‐dipole in interpretation of magnetic data is often employed in the analysis of magnetic anomalies (or their derivatives) caused by geologic bodies whose geometric shapes approach those ... -
Characterization of Environmental Gradients Using Physico-Chemical Measurements and Diatom Densities in Nairobi River, Kenya
(Taylor & FrancisCollege of Biological Sciences, University of Nairobi, 2003)Degradation of water resources due to anthropogenic activities is a major problem all over the world. Monitoring changes in water quality is expensive but essential for management of water resources. Diatom assemblages can ... -
Deterministic and stochastic modelling of technical reserves in short-term insurance contracts
(School of Mathematics, University of Nairobi, Kenya., 2008)Claims reserving for general insurance business has developed significantly over the recent past. This has been occasioned by the growth of the insurance market, with the risk underwriting process becoming more and ... -
THE MECHANICAL TRANSMISSION OF Trypanosoma evansi BY Haematobia minuta (DIPTERA: Mus c idae) AND Hippobosca camelina (DIPTERA: Hippobos c idae) FROM AN INFECTED CAMEL TO A MOUSE AND THE SURVIVAL OF TRYPANOSOMES IN FLY MOUTHPARTS AND GUT
(Department of Zoology, University of Nairob, 2003)The role of Haematobia minuta Linnaeus and Hippobosca camelina Leach in the transmission of camel trypanosomiasis was assessed. In a preliminary survey, there were no trypa nosomes in the mouth parts or gut of the ... -
Simulation of Coupled Heat and Mass Transfer in Granular Porous Media: Application to the Drying of Wheat
(Taylor & FrancisCollege of Biological Sciences, University of NairobiDepartment of Biosystems Engineering, University of Manitoba, Winnipeg, Manitoba, Canada, 2011)A mathematical model was developed to simulate the deep-bed convective drying of Algerian wheat and barley using the characteristics of the selected local varieties. The nonequilibrium model, composed of a system of partial ... -

Effect of nitrogen and water uptake on yield of wheat
(Kluwer Academic PublishersCollege of Biological Sciences, University of NairobiDepartment of Soils, Punjab Agricultural University, 141004, Ludhiana, India, 1992)For 2 years, field experiments were conducted to study the direct and interactive effects of water and nitrogen uptake at different growth stages on grain yield of wheat, grown on coarse textured alluvial soil of Ludhiana. ... -
Glycerol dehydration tests in Ménière's disorder using extratympanic electrocochleography
(College of Biological Sciences, University of NairobiDepartments of Otolaryngology and Medical Physics, University Hospital, Nottingham, 1981)Eleven patients with classical Méniére's disorder were examined electrophysiologically using extratympanic electrocochleography. All had been fully investigated audiologically and by electronystagmography. In addition to ... -
The ecological state of Lake Naivasha, Kenya, 2005: Turning 25 years research into an effective Ramsar monitoring programme
(Department of Zoology, University of Nairobi, KenyaDepartment of Biology University of Leicester, England, 2006)The present paper summarises the state of ecological knowledge in the lake based upon the research of the teams of Harper & Mavuti, funded by the Earthwatch Institute since 1987. It suggests how the research knowledge ... -
Otorhinolaryngology, head and neck surgery in Kenya--consequences of demographic parameters
(University of Nairobi.Department of Surgery, 2002-05)BACKGROUND: In the time of evidence based medicine the analysis of the influence of demographic parameters and different environmental factors on the treatment concepts in a country is often neglected. This is also true ... -

The characteristics of wet spells in Tanzania
(Department of Meteorology, University of Nairobi, 1982)In Tanzania where the bulk of economy depends largely on rain-fed agriculture, the study of daily rainfall patterns is of paramount importance. It is well known that wet or dry spells lasting for long duration may impose ... -
Temporal fluctuations of seasonal rainfall patterns in East Africa
(Department of Meteorology, University of Nairobi, 1984)In order to investigate temporal fluctuations in the seasonal rainfall over East Africa, monthly rainfall records from about 100 stations during" the period 1931 -75 were subjected to harmonic analysis on the yearly ... -
Sunflower pollinators in Kenya: Does diversity influence seed yield?
(University of NairobiDepartment of Zoology, 2007)A field experiment was carried out in 2004 and 2005 to study diversity of sunflower ( Helianthus annuus L.) pollinators and their influence on seed yield in Makueni district, a semi - arid area in Eastern Kenya. ... -
Assessment of soft X-ray imaging for detection of fungal infection in wheat
(ElsevierAgriculture and Agri-Food Canada, Cereal Research Centre, Winnipeg, MB, Canada R3T 2M9Department of Biosystems Engineering, University of Manitoba, Winnipeg, MB, Canada R3T 5V6, 2009)The potential of soft X-ray imaging to detect fungal infection in wheat was investigated. Healthy wheat kernels and kernels infected with the common storage fungi namely Aspergillus niger, A. glaucus group, and Penicillium ... -
Teleconnection between Seasonal Rainfall over East Africa and Global Sea Surface Temperature Anomalies
(Department of Meteorology, University of Nairobi, 1988)In this study, global sea surface temperature anomalies within ±300 latitudes of the equator were correlated with the time series of the major rotated principal component analysis (RPCA) modes of the seasonal rainfall ...
