On Local Linear Regression Estimation of Finite Population Totals in Model Based Surveys
(University of Nairobi, 2018)
In this paper, nonparametric regression is employed which provides an estimation of unknown finite population totals. A robust estimator of finite population totals in model based inference is constructed using the procedure ...
Electrophoretic Deposition of Titanium Dioxide Thin Films for Photocatalytic Water Purification Systems
(University of Nairobi, 2017)
In this study, electrophoretic deposition (EPD) technique was used to deposit titanium dioxide (TiO2) thin films on conducting glass substrates for application in water purification from organic contaminants. Phenol was ...
Raman Crystallinity and Hall Effect Studies of Microcrystalline Silicon Seed Layers
(University of Nairobi, 2017)
Aluminium induced crystallization (AIC) was used to crystallize sputtered amorphous silicon thin films on aluminium-coated glass substrates at annealing temperatures ranging from 250-520°C in vacuum. Crystalline volume ...
Containment Studies of Transgenic Mosquitoes in Disease Endemic Countries: The Broad Concept of Facilities Readiness
(University of Nairobi, 2018)
Genetic strategies for large scale pest or vector control using modified insects are not yet operational in Africa, and currently rely on import of the modified strains to begin preliminary, contained studies. Early ...
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 ...
Groundwater hydrodynamics of an Eastern Africa coastal aquifer during the recent La Niña 2016-17 drought
(University of Nairobi, 2019)
In 2016-17 much of East Africa was affected by a severe drought which has been attributed to Indian Ocean Dipole and El Niño Southern Oscillation conditions. Extreme events such as this have immediate and knock-on effects ...
Variation in host preferences of malaria mosquitoes is mediated by skin bacterial volatiles.
(University of Nairobi, 2017)
The host preferences of the anthropophilic mosquito species in the Anopheles gambiae complex (Diptera: Culicidae) are mediated by skin bacterial volatiles. However, it is not known whether these mosquitoes respond ...
The Potential For CO2 Geosequestration In Kenya: A Suitability Assessment Of The Lamu Basin
(University of Nairobi, 2019)
There is a consensus that current trends in climate change may be due to increasing concentrations of greenhouse gases (predominantly methane and carbon dioxide) from anthropogenic emissions. Among measures proposed for ...
Age and Origin of the Tsavorite and Tanzanite Mineralizing Fluids in the Neoproterozoic Mozambique Metamorphic Belt
(University of Nairobi, 2017)
The genetic model previously proposed for tsavorite- (and tanzanite-) bearing mineralization hosted in the Neoproterozoic Metamorphic Mozambique Belt (stretching from Kenya through Tanzania to Madagascar) is refined on the ...
