Dependence of temperature variation on the shape factor of a Solar Parabolic trough concentrator (ptc)
(Maseno University, 2018)Solar radiation energy incident on a collector can be converted into electricity using PV cells or thermal energy by means of solar thermal collectors. Solar radiation intensity is sometimes lower than required for suitable ... -
Habitat use and ecological carrying capacity for the Eastern black Rhinoceros (Diceros bicornis michaeli) in Ruma National Park, kenya
(Maseno University, 2018)The population of black rhinoceros has declined in African range states since 1960s due to poaching and habitat loss. In Kenya the species population declined from an estimated 20,000 in 1970 to less than 500 animals by ... -
Additive effects of DRAGONFLY (Pantala Flavescens) Nymph and Fungus (Beauveria Bassiana) on development and survival of Malaria Mosquito (Anopheles gambiae)
(Maseno University, 2018)Malaria continues to be a world-wide human health problem. Insecticide resistance challenge efficacy and sustainability of malaria control programs and therefore call for sustainable malaria control strategies. Environmental ... -
Morphological and molecular characterization, pathogenicity and co-infection effects of Ustilago kamerunensis with “candidatus phytoplasma oryzae” strain mbita 1 on napier grass growth tolerance under varying nutrients and moisture levels
(Maseno University, 2018)ABSTRACT: Napier grass (Pennisetum purpureum Schum.) is a leading feed for dairy animals in Eastern and Central Africa. In recent years the napier grass production has been threatened by napier head smut (NHS) and napier ... -
Optimization of Graphene oxide with methyl-β-Cyclodextrin and carbon Nanotubes with Polypyrrole for removal of lead (ii) and copper (ii) ions from water
(Maseno University, 2018)ABSTRACT Heavy metals pose risks to the humans and the environment. Lead (II) and copper (II) are of particular concern because they can cause irreversible damage to vital body organs. Their sources include leaded paints, ... -
Sorption of sulfonamides by γ-fe2o3 modified natural clay: Isotherms, Kinetics and Thermodynamics studies
(Maseno University, 2018)ABSTRACT In recent years, research has indicated the ... -
Effect of physicochemical factors and dyke on conservation of Oreochromis esculentus and Oreochromis variabilis in lake Kanyaboli, Kenya
(Maseno University, 2017)Lake Victoria witnessed mass extinction of native fish species that coincided with introductions of Lates niloticus and Oreochromis niloticus about five decades ago. Small populations of O. esculentus and O. variabilis ... -
Correlation Between Geomagnetic Field Variations and the Dynamics of the Equatorial Ionosphere Over East Africa
(Maseno University, 2017)The geomagnetic field shows regular variation during geomagnetic quiet conditions. However, during geomagnetic storms, it exhibits irregular fluctuations that can induce hazardous electric currents in ground based conductor ... -
Relationship between Physicochemical Factors and Occurrence of Vibrio Strains in the Environment of the Lake Victoria Basin
(Maseno, 2017)Aflatoxins, naturally occurring carcinogenic toxins produced by species of fungi, Aspergillus flavus and Aspergillus parasiticus, are associated with poor growth outcomes, especially stunting and underweight as well as ... -
Characterization of Xanthomonas Campestris Pv.Vesicatoria In African Nightshades (Solanum Scabrum Mill.) and its Control Using Extracts of Bidens Pilosa L. and Euphorbia Hirta L.
(2017)African nightshades (Solanum scabrum Mill.) are an important vegetable in terms of food security, medicinal values and income for most communities in Kenya. Its productivity is majorly affected by bacterial leaf spot disease ...
