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 ... -
Dynamics of Suspended Sediment Exchange and Transport in a Degraded Mangrove Creek in Kenya
(Royal Swedish Academy of SciencesDepartment of Zoology, University of Nairobi, Nairobi, KenyEcology and Environment Research Programme, Kenya Marine and Fisheries Research InstituteDepartment of Geography, University of Nairobi, 2002)This study focuses on sediment exchange dynamics in Mwache Creek, a shallow tidal mangrove wetland in Kenya. The surface area of the creek is 17 km2 at high water spring. The creek experiences semidiurnal tides with tidal ... -
Dynamics of the developing chick Chorioallantoic membrane assessed by Stereology, allometry, Immunohistochemistry and molecular analysis.
(University of Nairobi, 2016)The chick chorioallantoic membrane (CAM) is a widely used model for the study of angiogenesis, tumour growth, as well as drug efficacy. In spite of this, little is known about the developmental alteration from its appearance ... -
Dynamics of the East African climate
(Department of Meteorology, University of Nairobi. Nairobi. Kenya, 1993)Results of studies on regional climatic trends and the factors controlling the regional climate have been discussed in this paper. Potential impact of impending climatic change on the natural resources and socio-economic ... -
The Dynamics Of The Turbidity Maximum Zone In A Tropical Sabaki Estuary In Kenya.
(University of Nairobi, 2014-05)The spatial temporal variability and the behavio r of the Estuarine Turbidity Maximum (ETM) zone in the shallow, ephemeral, well - flushed Sabaki estuary located in the northern region of the Kenya coast, were studied ... -
Dynamics of topsoil carbon and nitrogen along a tropical forest–cropland chronosequence: Evidence from stable isotope analysis and spectroscopy
(ElsevierSchool of Biological Sciences, University of Nairobi, 2008)Analyses of δ13C and δ15N abundances and near infrared reflectance spectroscopy (NIRS) were used to evaluate the changes in SOC and total nitrogen (TN) content along a forest–cropland chronosequence in the margins of ... -
The Dynamics of Vector-Host Feeding Contact Rate with Saturation: A Case of Malaria in Western Kenya.
(University of Nairobi, 2013-10)In this study, we develop an expression for a saturated mosquito feeding rate in an SIS malaria model to determine its effect on infection and transmission dynamics of malaria in the highlands of Western Kenya. The basic ...
