Draft genome sequence of "Candidatus Phytoplasma Oryzae" strain mbita1, the causative agent of Napier grass stunt disease in Kenya.
(University of Nairobi, 2016)Phytoplasmas are bacterial plant pathogens with devastating impact on agricultural production worldwide. In eastern Africa, Napier grass stunt disease causes serious economic losses in the smallholder dairy industry. This ... -
Draft genomes, phylogenomic reconstruction and comparative genome analysis of three Xenorhabdus strains isolated from soil-dwelling nematodes in Kenya
(University of Nairobi, 2023)As a proven source of potent and selective antimicrobials, Xenorhabdus bacteria are important to an age plagued with difficult-to-treat microbial infections. Yet, only 27 species have been described to date. In this study, ... -
Drivers of ecosystem change and their impacts on human well-being in Lake Victoria basin
(2009)To offer an increased understanding of the spatial patterns, temporal, social and physical predictors of the conversion and transformations of land use in Lake Victoria basin, an assessment of proximate and underlying ... -
Drop-off patterns for engorged adult females, nymphs and larvae of Rhipicephalus appendiculatus
(University of Nairobi.School of Biological Sciences, 1991-12)A drop off rhythm of engorged Rhipicephalus appendiculatus Neumann was demonstrated for females and engorged nymphs, but not for larvae. Seventy per cent of 1279 engorged R. appendiculatus females dropped off the animals ... -

Dry season ecology of Anopheles gambiae complex mosquitoes at larval habitats in two traditionally semi-arid villages in Baringo, Kenya
(2/28/2011)Background: Pre-adult stages of malaria vectors in semi-arid areas are confronted with highly variable and challenging climatic conditions. The objective of this study was to determine which larval habitat types are ... -
Dry Storage And Use Of Potassium Nitrate Breaks Dormancy And Improves Seed Germination In Sesamum Latifolium (Gillet)
(University of NairobiCollege of Biological and Physical Sciences, 2011)Seeds of Sesamum latifolium, a medicinal species and wild progenitor of the cultivated Sesame (Sesamum. indicum), have been reported to express dormancy of non-deep physiological nature at maturity. Seed dormancy is not ... -
Durations of development and production estimates by two crustacean zooplankton species Thermocyclops oblongatus Sars (Copepoda) and Diaphanosoma excisum Sars (Cladocera), in Lake Naivasha, Kenya
(SpringerDepartment of Zoology, University of Nairobi, 1994)Durations of embryonic and post-embryonic development of the two dominant zooplankton crustaceans Thermocyclops oblongatus (Copepoda) and Diaphanosoma excisum in Lake Naivasha were determined at various lake water temperatures ... -
Dye-Sensitized and Amorphous Silicon Photovoltaic (PV Devices' Outdoor Performance: A Comparative Study
(2013)The performance of a dye-sensitized solar module (DSSM) has been investigated under different air mass (AM), irradiance intensity and temperature conditions in Nairobi, Kenya. The good response of the DSSM to short wavelength ... -
Dynamic channel sharing strategies through game-theoretic reinforcement learning
(University of Nairobi, 2014-03)—Random access protocols are used by multiple nodes in wireless networks to effectively share a wireless channel for data transmission. While competing for the channel, the nodes seek to achieve an individual or group ... -
Dynamic ecology of Aldabran seabird communities
(University of Nairobi, 1979-07)The characteristics of the present seabird community of Aldabra are described, and compared briefly with others in the tropics. By comparison with Pacific Ocean communities, Aldabra is deficient especially in petrels and ... -
Dynamic Resource Allocation: A comparison of First Price Sealed Bid and Vickrey Auctions
(School of Computing and Informatics, 2008)Resource allocation involves assigning the resources to the resource users. Where the resources and the resource users do not change with time, the resource allocation problem can be solved as a scheduling problem. Where ... -
A dynamical model for stage-specific HIV incidences with application to sub-Saharan Africa
(University of NairobiDepartment of Mathematics, 2003)Abstract In this paper a deterministic model for HIV epidemic with three stages of disease progression among infected patients is discussed. It is assumed that the patient once infected experiences disease progression ... -
Dynamics of chlorpyrifos in water from upper Tana River in Kenya
(University of Nairobi, 2014)Water covers 70.9% of the Earth's surface (WFB, 2008), and is vital for all known forms of life (WFB, 2008). The specific contaminants leading to pollution in water include a wide spectrum of chemicals like Persistent ...
