Temperature and heat in informal settlements in Nairobi.
(University of Nairobi, 2017)
Nairobi, Kenya exhibits a wide variety of micro-climates and heterogeneous surfaces. Paved roads and high-rise buildings interspersed with low vegetation typify the central business district, while large neighborhoods of ...
First-principle investigation of structural, electronic and magnetic properties of Co2VIn and CoVIn Heusler compounds
(University of Nairobi, 2017)
Investigation of the structural, electronic and magnetic properties of full-Heusler Co2VIn as well as half-Heusler CoVIn Cobalt based Heusler compounds using density functional theory (DFT) leads to the general conclusion ...
Influence of Perception and Quality of ICT‐Based Agricultural Input Information on Use of ICTs by Farmers in Developing Countries: Case of Sikasso in Mali
(University of Nairobi, 2017)
Small-scale cereal farmers dominate agricultural activities in developing countries. These agricultural activities are characterized by low productivity due to lack of agricultural input information. ...
Effects of Tio2 Film Thickness and Electrolyte Concentration on Photovoltaic Performance of Dye-sensitized Solar Cell
(University of Nairobi, 2017)
Effects of film thickness and electrolyte concentration on the photovoltaic performance of TiO2-based dye-sensitized solar cell (DSSC) were studied. Nanocrystalline anatase TiO2 thin films with varying thicknesses (3.2–18.9μm) ...
Quantifying the intensity of permethrin insecticide resistance in Anopheles mosquitoes in western Kenya.
(University of Nairobi, 2017)
BACKGROUND:
The development and spread of resistance among local vectors to the major classes of insecticides used in Long-Lasting Insecticidal Nets (LLINs) and Indoor Residual Spraying (IRS) poses a major challenge to ...
Temporal genetic differentiation in Glossina pallidipes tsetse fly populations in Kenya.
(University of Nairobi, 2017)
BACKGROUND:
Glossina pallidipes is a major vector of both Human and Animal African Trypanosomiasis (HAT and AAT) in Kenya. The disease imposes economic burden on endemic regions in Kenya, including south-western Kenya, ...
Emphasis on Photovoltaic (PV) Solar System Installation Training: A Case Study of a PV Solar System Installed in Makueni County, Kenya
(University of Nairobi, 2017)
The installation of Photovoltaic (PV) solar systems in institutions as well as homesteads in the rural areas in Kenya is increasing at a high rate; and so is the need for the stake holders to make sure the ...
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 ...
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 ...
