Spatial patterns of species diversity in Kenya
(2001)It is evident to any biologist that small-bodied species within a given higher taxon (order, class, phylum, etc) tend to be represented by more individuals. Hence smallbodied species are generally more abundant than ... -
Spatial profiling of Malaria Epidemiology in a highland area of low Endemicity: transmission, diagnosis and Malarial Anaemia in Nandi county-Kenya
(Maseno University, 2016)Malaria remains prevalent in many parts of Kenya but areas in the highlands of Nandi North sub-county have reported declining incidences of malaria infection and disease burden, and between April 2007 and March 2008 a ... -
Spatial variations in nutrients and other physicochemical variables in the topographically closed Lake Baringo freshwater basin (Kenya)
(Lakes & Reservoirs: Research & Management, 2014)Spatial physicochemical parameters were determined from 39 sampling sites distributed throughout Lake Baringo during December 2010. Mean values of temperature, dissolved oxygen concentration and electrical conductivity ... -

Spatio-Temporal Dynamics in Urban Land Use/Land Cover Change in Urbanizing Sub-Catchments In The Upper Ewaso Ng’iro North River Basin, Kenya
(East African Scholars Publisher, 2021)Massive expansion of urban areas leads to land use/land cover (LULC) changes which significantly alter the hydrology of river basins. Yet, systematic and logical information on the spatio-temporal dynamics of urban LULC ... -
A Spatiotemporal Analysis of HIV-Associated Mortality in Rural Western Kenya 2011–2015
(2018)Background: Reliable data on the HIV epidemic is critical for the measurement of the impact of HIV response and for the implementation of further interventions. Methods: We used mortality data from the Kombewa health ... -
Spectra of Composition Groups on the Weighted Dirichlet Space of the Upper Half-Plane
(Springer, 2020)We prove that the group of weighted composition operators induced by contin uous automorphism groups of the upper half plane U is strongly continuous on the weighted Dirichlet space of U, Dα(U). Further, we investigate ... -
Spectral analysis of certain groups of isometries on Hardy and Bergman spaces
(Academic Press, 2017-12-15)Using the similarity theory of semigroups as well as spectral theory, we obtain the resolvents of the generators of strongly continuous groups of isometries on the Hardy and Bergman spaces. These groups are obtained as ... -
Spectral Properties of Semigroups of Weighted Composition Operators on the Bloch Space
(Maseno University, 2019)Semigroups of composition operators on spaces of analytic functions have interested mathematicians for many years. The breakthrough in Hardy spaces was given by Berkson and Porta. On Bergman and Dirichlet spaces, Siskakis ... -
Spectroscopic characterization of the metal cation siting and the adsorbate-cation interactions in copper (II) and cobalt (II) exchanged faujasite-X zeolite
(State University of New York at Binghamton, 2006)Toxic chemicals are abundant in the environment and their detection often requires very costly and time consuming methods. Where such molecules are able to interact with the transition metal cations, their characteristic ... -
Speech by Prof Julius O. Nyabundi Phd, OGW, Vice-Chancellor, Maseno University On the Regional Scientific Conference On Forced Displacement and Mixed Migration in The East and Horn of Africa: Current Trends and Future Directions On 8th May 2019 At Radisson Blue Hotel, Nairobi, Kenya.

The spleen bacteriome of wild rodents and shrews from Marigat, Baringo County, Kenya
(PeerJ Inc., 2021)There is a global increase in reports of emerging diseases, some of which have emerged as spillover events from wild animals. The spleen is a major phagocytic organ and can therefore be probed for systemic microbiome. This ... -
Split application of nitrogen fertilizer rates in two tea cultivars grown in the Eastern and Western highlands of Kenya: I. Confirmatory results on yield effects.
(Tea Research Foundation of Kenya, 2000)Two experiments were conducted in Kericho and Kangaita, Kenya during 19991-98 to investigate the effects of nitrogen fertilizer rates (50, 100, 200, 400 and 800 kg/ha) and frequencies of application (1, 2 and 4 split ... -
: Spray Pyrolysis Technique (SPT) was used to deposit thin films (TFs) of cadmium stannate, doped with iron (Fe) for the first time. The precursor solutions that were used wereprepared at a concentration of 0.1M, doped with Feand then sprayed onto the pre-heated glass slides immediately at deposition temperatures of 350 ± 7°C, 400 ± 7°C and 450 ± 7°C. The optical properties of the deposited Fe-doped TFs were studied in the wavelength range of 300-1100nm. The X-Ray diffraction (XRD) studies showed that the TFs were orthorhombic with growth orientation along the (2 0 0) direction. Film thickness of 85 ± 10 nm was obtained. It was found out that anincrease in the deposition temperature increased transmittance and band gap, but decreased absorption coefficient, extinction coefficient and refractive index, which was attributed to the improvement in crystallinity of the deposited TFs. Doping reduced transmittance and band gap, but increased refractive index, absorption coefficient and extinction coefficient, which was attributed to the increase in free carriers. KEYWORDS:cadmium stannate, deposition temperature, iron-doped, optical properties of cadmium stannate
(Elsevier, 2020)The elastic properties of the orthorhombic cadmium stannate (Cd2SnO4) were investigated using density functional theory, applying both energy-strain relationship (which is found in the literature) and stress-strain ... -
