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 ...
Viability and Dormancy of Rice Seeds after Storage and Pre-Treatment with Dry Heat and Chemical Agents
(University of Nairobi, 2017)
Inappropriate seed packaging and seed dormancy affects seed quality and consequently leads to reduced crop stand, low seedling vigour and reduced yields. The objective of the study was to determine the effect of seed ...
Seroepidemiological Survey of Rift Valley Fever Virus in Ruminants in Garissa, Kenya
(University of Nairobi, 2017)
Introduction: Rift Valley fever (RVF) is a vector-borne zoonotic disease caused by phlebovirus in the family Bunyaviridae. In Kenya, major outbreaks occurred in 1997–1998 and 2006–2007 leading to human deaths, huge economic ...
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 ...
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 ...
Adsorption Of Malachite Green From Aqueous Solutions Onto Rice Husks: Kinetic And Equilibrium Studies
(University of Nairobi, 2017)
A study was done to evaluate the removal of a cationic dye from simulated waste water onto rice husks (RH). Spectroscopic methods such as FTIR and SEM/EDX were used for adsorbent characterization. Experimental dependency ...
Prevalence of fibromyalgia syndrome in diabetics with chronic pain at the Kenyatta National Hospital
(University of Nairobi, 2017)
Background: Fibromyalgia Syndrome (FMS), an increasingly recognized disorder with heightened response to pressure, characterized by Chronic Widespread Pain (CWP), for which no other cause can be identified. Diabetes Mellitus ...

(University of Nairobi, 2017)
Theeffects of 2 Neem derivatives, Neem oil (NO) and Neem Seed Powder (NSP),on various physiological parameters of the brown ear tick, Rhipicephalus appendiculatus,the vector for Theileria parva. ...
Effect Of Intercropping Maize-Soybean On Grain Quality Traits In Kenya
(University of Nairobi, 2017)
An study was carried out in Kenya to assess the suitability of three promiscuous soybean varieties
(SB19, GAZELLE and TGX1990-5F) intercropped with Maize (Duma 43). A randomised complete
block design was used replicated ...
