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 ... -
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 ... -
Evaluation of anticonvulsant activity of extracts and isolates from Maytenus Heterophylla
(Maseno University, 2017)Convulsion is a chronic neurological disorder that develops in up to 5% of the world’s population with prevalence of nearly 88% occurring in Sub-Saharan Africa, prompting serious medical, social, health related stigma ... -
Quantum entanglement properties of polarization states of a semi-classical optical parametric oscillator
(Maseno University, 2017)Entanglement is a fundamental feature of quantum mechanics which originated from the 1935 paper of Einstein, Podolsky and Rosen (EPR) and has been demonstrated in many quantum systems for development of quantum technology. ... -
Effect of NPK blended fertilizer application on soil chemical properties, growth, Chlorophyll content and nutrient uptake on Finger millet (Eleusine coracana l. gaertn.) grown in acidic soils.
(Maseno University, 2017)Finger millet (Eleusine coracana L) is one of the most important cereal crops in Kenya. It is an important staple food rich in minerals and vitamins required for good health. Finger millet has the ability to grow in stressful ... -
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 ... -
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 ... -
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 ... -
Effects and the relationship between nitrogenous fertilizer application rates and plucking intervals on some soil quality indicators and yield of tea (Camellia Sinensis (l.) in eastern Africa tea growing regions
(Maseno University, 2018)Eastern Africa tea is grown in high rainfall areas causing high nutrients depletion through leaching and surface run-off. Nutrients are also removed with harvested crop. The depletion requires nutrients replenishment through ... -
Susceptibility patterns and tolerance mechanisms of Staphylococcus Epidermidis biofilms to Physico-chemical stress exposure
(Maseno University, 2018)Bacterial biofilms remain a major public health burden. Staphylococcus epidermidis biofilm is the predominant cause of biofilm-associated infections. Kisumu county has a high circulation of antibiotic resistance genes, ... -
Survey of greenhouse gas fluxes from different vegetation, seasons and landscape units in small scale farming systems in lower Nyando-Kenya
(Maseno University, 2018)Greenhouse gases (GHGs) emissions data from large-scale agricultural activities are available. In developing countries, e.g. Kenya, agriculture is dominated by smallholder farming, data on the assessment of possible ... -
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 ... -
Acquired plasmodium falciparum-specific antibody responses are associated with efficacy to artemisinin-based combination therapy (act) in the treatment of uncomplicated malaria in Kombewa, western, Kenya
(Maseno University, 2018)Significant advancement achieved in the chemoprophylaxis and chemotherapy of malaria has been pivotal for eventual reduction of malaria prevalence. However, a major setback has been the emergence of resistance to antimalarial ... -
Differences in Antibacterial resistance profiles and genes between Escherichia coli isolates from humans and black rhinoceros in Lambwe Valley, Kenya.
(Maseno University, 2018)Antimicrobials have been in use for decades in disease management, but emergence of resistant pathogens such as Escherichia coli have rendered its future of concern to public health. Increased human-wildlife interaction ...
