Differential transcription of two highly divergent gut-expressed Bm86 antigen gene homologues in the tick Rhipicephalus appendiculatus
(College of Biological and Physical Sciences ,Department of Biological Science, 2011)The transcriptional control of gene expression is not well documented in the Arthropoda. We describe transcriptional analysis of two exceptionally divergent homologues (Ra86) of the Bm86 gut antigen from Rhipicephalus ... -
DifiFerentiation of Vector Species of Phlebotominae (Diptera: Psychodidae) in Kenya by Chorionic Sculpturing of Their Eggs
(Entomological Society of AmericaDepartment of Entomology, University of Nairobi, Kenya, 1992)Chorionic sculpturing on eggs of Phlebotomus pedifer Lewis, Mutinga, and Ashford; the closely related Phlebotomus aculeatus Lewis, Minter, and Ashford (=P. elegonensis Ngoka, Madel, and Mutinga); and Phlebotomus martini ... -
Digestive Endo-proteases from the Midgut Glands of the Indian White Shrimp, Penaeus indicus (Decapoda:Penaeidae) from Kenya
(2005)In order to provide information on the digestive capacity of marine crustacea of mariculture potential in Kenya with a view to aiding the development of suitable feeds to support the industry, a biochemical survey was made ... -
The digital matatu project: Using cell phones to create an open source data for Nairobi's semi-formal bus system
(University of Nairobi, 2015-12)In many of the world's growing cities, semi-formal buses form the basis of public transit systems. However, little open and standardized data exist on these systems. The Digital Matatus project in Nairobi, Kenya set out ... -

Direct rapid quality assurance analysis of complex matrix materials: A chemometrics enabled energy dispersive X-ray fluorescence and scattering spectrometry application
(University of Nairobi, 2022)Compared to energy dispersive X-ray fluorescence (EDXRF) that is limited to analysis of elements (Z ≥ 13) via fluorescence and which is hardly direct, energy dispersive X-ray fluorescence and scattering (EDXRFS) spectrometry ... -
Directed ring-opening of 1,5-dioxaspiro[3.2]hexanes: selective formation of 2,2-disubstituted oxetanes
(2003)1,5-Dioxaspiro[3.2]hexanes undergo ring-opening reactions with many heteroatom nucleophiles to provide alpha-substituted-beta'-hydroxy ketones. However, certain Lewis acidic nucleophiles provide 2,2-disubstituted oxetanes. ... -
Directed Ring-Opening of 1,5-Dioxaspiro[3.2]hexanes: Selective Formation of 2,2-Disubstituted Oxetanes
(Department of Chemistry, University of Nairobi, 2003)1,5-Dioxaspiro[3.2]hexanes undergo ring-opening reactions with many heteroatom nucleophiles to provide α-substituted-β‘-hydroxy ketones. However, certain Lewis acidic nucleophiles provide 2,2-disubstituted oxetanes. Herein, ... -
Disappearing medicinal plants in Mt. Kenya forests , Kenya: a case study of East African green heart ( Warburgia ugandensis sprague)
(2013)Natural disturbances and human activities are significantly affecting indigenous trees species in forests. Warburgia ugandensis is a plant highly valued for its medicinal properties, timber and fuel among other uses. Many ... -
Discovery of a novel species, Theileria haneyi n. sp., infective to equids, highlights exceptional genomic diversity within the genus Theileria: implications for apicomplexan parasite surveillance.
(University of Nairobi, 2018)A novel apicomplexan parasite was serendipitously discovered in horses at the United States - Mexico border. Phylogenetic analysis based on 18S rDNA showed the erythrocyte-infective parasite to be related to, but distinct ... -

Dispersal distance of rice (Oryza Sativa L.) pollen at the Tana River delta in the coast province, Kenya
(School of Biological SciencesAfrican Journal of Biotechnology Vol. 8 (10): 2265-2270., 2009)Rice is a staple food in Kenya and its production needs to be increased. Genetically modified (GM) rice may be a solution, but before it can be introduced, potential ecological impacts, such as pollen mediated gene flow ... -
The dissipation and degradation of methoxy‐14C malathion in soil under tropical conditions
(University of NairobiDepartment of Chemistry, University of NairobiDepartment of Chemistry, Maseno University, 2000)l4C‐malathion[S‐1,2‐bis(ethoxycarbonyl) ethyl O,O‐dimethyl phosphorodithioate] has been studied in soil under tropical field conditions by applying the 14C‐malathion pesticide to soil in Polyvinyl chloride (PVC) pipes and ... -
Dissipation behavior of malathion and dimethoate residues from the soil and their uptake by garden pea (Pisum sativum)
(University of NairobiCollege of Biological and Physical Sciences, 2000)The dissipation of malathion and dimethoate from soil and their uptake by garden peas was studied in a greenhouse at 10-26°C. Twenty-one-day-old seedlings were treated with 50% EC malathion or 40% EC dimethoate, labelled ... -
