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 ... -
Estimation of Annual Effective Dose and Radiation Hazards due to Natural Radionuclides in Homa Mountain, southwestern, Kenya
(ScholarOneSchool of Physical Sciences, 2000)The radiological hazard of naturally occurring radioactive material in Homa Mountain found in southwestern Kenya was investigated after 210 point measurements and 44 samples were analyzed. In situ measured average outdoor ... -

Estimation of climatic parameters from solar indices using ground based data from Kenya, East Africa
(University of Nairobi, 2011)The daily meteorological data of relative humidity, maximum, minimum, and average temperatures obtained from five stations of the Kenya Meteorological Department over the period 1986 to 2005 were filtered and reduced to ... -
Estimation of evapotranspiration using fuzzy state models.
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2000)The suitability of fuzzy logic was examined for estimating evapotranspiration (ET). Two fuzzy ET models, one using two input weather parameters (solar radiation and relative humidity), and the other using three input weather ... -
Estimation of heritability of susceptibility to infection with Theileria parva in the tick Rhipicephalus appendiculatus
(1995)Heritability of susceptibility to infection with Theileria parva was estimated from full sib families of Rhipicephalus appendiculatus ticks. Male and female ticks of 2 stocks were mated singly. Nineteen full sib families ... -
Estimation of IBNR Claims Reserves Using Linear Models
(School of Mathematics, University of Nairobi, Kenya, 2008)Stochastic models for triangular data are derived and applied to claims reserving data. The standard actuarial technique, the chain ladder technique is given a sound statistical foundation and considered as a linear ... -
Estimation of Radiative Forcing due to Aerosols over Selected Sites in Kenya
(Meteorology, 2011)Atmospheric aerosols modulate the radiative budget and ambient air quality of the atmosphere, thus, there is a need to develop both analytical and computational methodological techniques that determine their physical, ... -
Estimation of reference crop evapotranspiration using fuzzy state models
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2001)Daily evapotranspiration (ET) rates are needed for irrigation scheduling. Owing to the difficulty of obtaining accurate field measurements, ET rates are commonly estimated from weather parameters. A few empirical or ... -

(College of Physical and Biological Sciences, 2012)Ethnopharmacological relevance Diabetes mellitus is a growing problem in many developing countries and the financial burden associated with it is enormous. In traditional African communities, majority of people relies ... -
An ethnobotanical study of medicinal plants used by the Nandi people in Kenya.
(University of NairobiCollege of bilogical and physical science, 2008)Ethnopharmacological relevance The study of local knowledge about natural resources is becoming increasingly important in defining strategies and actions for conservation or recuperation of residual forests. Aims of ... -
Ethnobotanical Survey and Antimicrobial Evaluation of Medicinal Plants used by the Samburu Community (Kenya) for treatment of Diarrhorea
(Department(s) of Zoology, University of Nairobi, 2009)The Samburu are a marginalized nomadic people who have no access to conventional medical services. The Samburu therefore depend on traditional medical practice and medicinal plants for most of their medicare. The medicinal ... -
