Knowledge and attitudes to malaria control and acceptability of permethrin impregnated sisal curtains
(College of Physical and Biological Sciences, 1999)OBJECTIVES: The objectives of this study were to conduct a survey on the knowledge and practices relating to malaria prevention and treatment in two rural communities in Western Kenya, and to determine the acceptability ... -
Soil condition classification using infrared spectroscopy: A proposition for assessment of soil condition along a tropical forest-cropland chronosequence
(ElsevierSchool of Biological Sciences, University of Nairobi, 2008)Soil fertility depletion in smallholder agricultural systems in sub-Saharan Africa presents a formidable challenge both for food production and environmental sustainability. A critical constraint to managing soils in ... -
Serological evidence for long-term epstein–barr virus reactivation in children living in a holoendemic malaria region of Kenya†
(College of Physical and Biological Sciences, 2009)To study the long term the effects of chronic exposure to P. falciparum malaria on Epstein–Barr virus (EBV) reactivation in children, EBV-specific antibody levels were measured in a cross-sectional survey of two groups of ... -
Crystallisation kinetics, glass forming ability and thermal stability in glassy Se100 − xInx chalcogenide alloys
(ElsevierDepartment of Physics, University of Nairobi, 2011)Differential scanning calorimetry (DSC) studies have been done under non-isothermal conditions at different heating rates for glassy Se100 − xInx (5 ≤ x ≤ 20) alloys. DSC traces with well-defined endothermic and exothermic ... -

Anthocyanin-sensitized nanoporous TiO2 photoelectrochemical solar cells prepared by a sol–gel process
(Springer, 2004)Photoelectrochemical solar cells comprising a colloidal TiO2 photoelectrode and sensitized with anthocyanin pigments, delphinidin purple and cyanidin 3,5-diglucose extracted from Hibiscus sabdariffa and Ribes nigra plants, ... -
Topography and malaria transmission heterogeneity in western Kenya highlands: prospects for focal vector control
(College of Physical and Biological Sciences, 2006)Background Recent resurgence of malaria in the highlands of Western Kenya has called for a more comprehensive understanding of the previously neglected complex highland vector ecology. Besides other drivers of malaria ... -
Electron transport and recombination in dye sensitized solar cells fabricated from obliquely sputter deposited and thermally annealed TiO2 films
(ElsevierDepartment of Physics, University of Nairobi, 2007)Dye sensitized solar cells based on annealed titanium dioxide films prepared by oblique reactive DC magnetron sputtering have been investigated in detail. Electron transport and recombination were studied using intensity-modulated ... -

Some Observations on the Biting Behavior ofAnopheles gambiae s.s, Anopheles arabiensis, andAnopheles funestusand Their Implications for Malaria Control
(College of Physical and Biological Sciences, 1996)Studies were carried out in three villages in western Kenya on the biting behavior ofAnopheles gambiae s.s., Anopheles arabiensis,andAnopheles funestus.Blood feeding behavior and departure from houses were studied under ... -
Comparative assessment of total phenolic content in selected medicinal plants
(2010)This study was to compare the total phenolic (TP) content in extracts from eleven plant materials collected at different geographical locations in Kenya, Nigeria, and USA. These plants have been selected because the majority ... -

Structure, Composition, and Morphology of Photoelectrochemically Active TiO2-xNx Thin Films Deposited by Reactive DC Magnetron Sputtering
(American Chemical Society, 2004)Films of nitrogen-doped TiO2 were made by reactive DC magnetron sputtering in a mixture of argon, oxygen, and nitrogen. The nitrogen gas ratio Φ was varied in the 0 < Φ < 0.025 range during the depositions, resulting in ... -
Resolution of ascorbic acid or catecholamine and indole alkaloid mixtures by pulse voltammetry at highly polished glassy carbon
(1994)Metallographic polishing of glassy carbon electrodes (GCEs) yields well-defined oxidation peaks for two- and three-component mixtures of ascorbic acid, dopamine (DA), catechol, and hydroquinone. Linear calibration plots ... -
