Computational study of the structural, Electronic, optical and thermal properties of Hexagonal and cubic Germanium-antimony-telluride
(Maseno University, 2016)The electronic, optical and thermal properties of hexagonal and cubic phases of Ge2Sb2Te5 (GST) have been calculated using density functional theory (DFT) as implemented in the QUANTUM ESPRESSO computer package. GST is ... -
Comparison of Variations in Soil-Foliar Nutrients Levels and Productivity of Three Ratoon-Sugarcane Cultivars Due to Nitrogen-Potash Rates and Harvesting Age in Western Kenya
(2016)Sugarcane productivity in Kenya has declined despite increased acreage and new cultivars possibly due to use of old-cultivar agronomic inputs. The N-K2O optimal rates for new cultivars are unknown. Kenya Sugar Industry ... -

(Maseno University, 2016)Incidence of Salmonella resistance to various antibiotic agents, especially to the commonly available antibiotics in Kenya, is rising. Genetic elements such as Class 1 integrons have an important role in development and ... -
Fate studies of chlorsulfuron in selected soils within the Mara river basin of Kenya
(Maseno University, 2016)ABSTRACT Chlorsulfuron is a sulfonylurea herbicide used to control broadleaf and grass weeds in wheat farms within the Mara River Basin. It is assumed to be environmentally safe due to low application rates, relatively ... -
Evaluation of chlorpyrifos ethyl elisa kit and assessment of use and spatial distribution and temporal trend of selected organophosphate and carbamate pesticides residues in water, sediment and fish from lake Naivasha
(Maseno University, 2015)Heavy seasonal use of specific organophosphate and carbamate in the catchment area of Lake Naivasha is a potential cause of pollution of sediment, water and fish in the lake. However, there is lack of data on the potential ... -
Association of Serumestradiol levels and bone marrow Estrogen receptor densities in acute Myelocytic leukemia patients in Moi teaching and referral hospital, Kenya
(Maseno University, 2016)Acute Myelocytic Leukemia (AML) is a cancer of the bone marrow characterized by arrested maturation along with uncontrolled proliferation of hematopoietic progenitor cells. Mostly, it affects persons of age 65years and ... -
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 ... -
Serum-derived immune factors as correlates of Artemisinin-based combination therapy efficacy in treatment of uncomplicated Plasmodium falciparum malaria in Kombewa, Western Kenya
(Maseno University, 2018)Artemisinin-based combination therapy (ACT) is recommended first-line treatment for malaria in a number of Sub-Saharan African (SSA) countries. Recent reports of decline in efficacy of ACT and emergence of ACT resistant ... -
Comparison of Genexpert and line probe assay for detection of Mycobacterium Tuberculosis and Rifampicin mono-resistance in Kenya
(Maseno University, 2018)substantial human morbidity and mortality globally. About 10.4 million TB cases and 1.4 million deaths worldwide were reported in 2015. Kenya is among the 22 countries with highest TB burden. Microscopy is routinely used ... -
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 ... -
Prevalence of sickle cell trait and glucose-6-phosphate Dehydrogenase deficiency and their association with immunoglobulin- G antibody responses to selected Plasmodium Falciparum Antigens in Kanyawegi sub-location, Western Kenya
(Maseno University, 2018)The prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency and sickle cell trait (SCT) may vary within very close localities in malaria endemic areas due to dynamics in malaria incidence and demographics. ... -
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 ... -
