Epidemiology of Schistosoma mansoni infection on the Kano Plain of Kenya.
(University of Nairobi.Department of zoology, 1971)1. The results of a survey of 740 school children showed a very low prevalence of S. mansoni infection on the Kano Plain; no infected children were found in 7 out of 16 schools examined and the highest infection rate was ... -
Equatorial ionospheric absorption
(1956)A study has been made of the variation of absorption with frequency and sun's zenith distance χ at Ibadan at vertical incidence. Since the propagation at Ibadan is almost purely transverse, simple theories in terms of ... -
Equatorial paleomagnetic time‐averaged field results from 0–5 Ma lavas from Kenya and the latitudinal variation of angular dispersion
(Department of Geological Sciences, University of Florida, Gainesville, Florida, USADepartment of Earth and Planetary Sciences, Rutgers, State University of New Jersey, USADepartment of Physics, University of Nairobi, Kenya, 2010)[1] Lavas of Pliocene-Pleistocene age were sampled in two regions in Kenya: Mount Kenya on the equator and the Loiyangalani region, east of Lake Turkana, at about 3°N. We sampled 100 sites distributed around the Mount Kenya ... -
Equatorial spread-F at Ibadan, Nigeria
(University of Nairobi, 1961)The characteristics of equatorial spread-F at Ibadan (magnetic latitude 3°S) are investigated including nocturnal, seasonal, solar-cycle and magnetic disturbance variations; and all of these are found to show marked ... -
Equatorial spread-F irregularities observed at Nairobi and on the transequatorial path Lindau-Tsumeb
(Department of Physics, University of Nairobi, 1973)During February and April 1972, 3 weeks of observations of irregularity patches were made by two methods: 1. (a) Non-great-circle propagation on the transequatorial path Lindau-Tsumeb; 2. (b) Radar backscatter at ... -
Equatorial Total ozone as a predictor of sea surface temperature
(university of Nairobicollege of biological and physical science, 2003) -
Equatorial total ozone as a predictor of sea surface temperatures useful for East African seasonal rainfall prediction
(Meteorology, 2003)Monthly total ozone data for the period 1979 to 2001, obtained from Total Ozone Mapping Spectrophotometer (TOMS), for two equatorial African locations of Nairobi, Kenya and Mahe, Seychelles were correlated with monthly ... -
Equilibrium and Kinetic Studies of Cu(Ii) Removal from Aqueous Solutions Using a Kenyan Micaceous Mineral.
(University of Nairobi, 2017)Copper (II) sorption on a Kenyan micaceous mineral (Mica-K) was studied in the batch mode. The effects of different experimental parameters such as; initial concentration, contact time, sorbent dose, pH, particle size, ... -
Equilibrium and kinetics studies for the adsorption of aqueous Cu (II) ions onto mangroves biomass
(University of Nairobi, 2015-08)In this study, adsorption of copper from aqueous solutions was investigated using mangrove biomass from the Kenyan Coast. The efficacy of mangrove biomass on the removal of copper (II) ions from aqueous solutions was ... -
Erratum: Effect Of Reflecting Boundaries On The Transport Of Resonance Radiation. II. Comparison With Diffusion Theory
(University of Nairobi, 1970) -
An Error Analysis and Convergence of a Quadrature Formula to Invert Laplace Transforms
(University of Nairobi.Department of Mathematics, University of Nairobi, 1977)The use of an expression for the exponential function exp(st) in Bromwich's integral, which incorporates a Padé approximation, yields a well known quadrature formula and its error terms. The error is then analysed for ... -
Essential Oil of Lippia wilmsii H.H.W. Pearson". Rev.Latinoamer. Quim., 20 (3), 143-14

Essential oils of indigenous plants protect livestock from infestations of Rhipicephalus appendiculatus and other tick species in herds grazing in natural pastures in western Kenya
(University of Nairobi, 2018)The effects of formulated essential oils of Tagetes minuta and Tithonia diversifolia on Rhipicephalus appendiculatus infesting livestock were evaluated in semi-field experiments. Forty-five zebu cattle naturally infested ... -
Essentiality of a newly identified carbohydrate-binding module for the function of CelB (BH0603) from the Alkaliphilic Bacterium Bacillus halodurans
(Department of Chemisty, University of Nairobi, 2006-10)CelB (BH0603) from Bacillus halodurans is a modular glycoside hydrolase with a family 5 catalytic module, an immunoglobulin-like module, and module PfamB of unknown function. The recombinant PfamB module bound to Avicel ... -
Establishment of pine woolly aphid, Pineus pini (Gmelin) (Adelgidae) on some host trees in Kenya
(1982)The establishment of Pineus pini (Gmel.) on 6 common species of pine in Kenya was examined in the laboratory in relation to possible causes for observed differences in the rates of infestation on different host species in ... -
Estimating IBNR Claims Reserves for General Insurance Using Archimedean Copulas
(School of Mathematics, University of Nairobi, Nairobi, Kenya, 2013)Claims reserving for general insurance business has developed significantly over the recent past. There has always been a slight mystery in short-term insurance contracts of how to go about reserving for claims, which ... -
Estimating IBNR Claims Reserves using Gamma model and GLIM
(University of Nairobi.School of Mathematics, 2003)This paper is concerned with the prediction of outstanding claims amounts on a portfolio of general insurance policies, the extension of the standard actuarial techniques (the chain ladder technique) and the development ... -
Estimating net primary production from measurements made on soil organic-matter
(1999)A model for the turnover of organic matter in soil, ROTHC-26.3, can be used to calculate how much organic C needs to enter a soil annually in order to maintain a specified stock of soil organic C. The annual return of ... -
Estimating the impacts of land cover change on runoff using SWAT: Case study: Nzoia catchment, Kenya
(2009)The SWAT model was used to investigate the impact of land-cover changes on the runoff of the River Nzoia catchment, Kenya. The model was calibrated against measured daily discharge, and land-cover changes were examined ...
