Binding of opsonized immune complexes to Erythrocyte crlicd35 inhibits TNF-a production by restricting immune complex uptake by macro phages
(Maseno university, 2008)Previous studies have shown that children suffering from severe malaria have elevated concentrations of TNF-a, increased levels of circulating immune complexes (ICs) and decreased levels of complement regulatory proteins ... -
Characterization of variability of Total Electron Content (TEC) over Malindi
(Maseno University, 2013)The dynamics of the ionosphere depends largely on solar activity. The attenuation of radio signals as they propagate through the ionosphere can be determined through a parameter called the Total Electron Content (TEC),which ... -
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 ... -
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 ... -
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 ... -
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 ... -
The cooling effect of air on flat plate solar energy collectors
(Maseno university, 2021)Use of solar energy devices requires that they be exposed to receive maximum solar radiation. Unfortunately, the intensity of solar radiation incident on these devices varies throughout the day with the position of the sun ... -
Correlation between equatorial electrojet and the occurrence of equatorial ionisation anomaly over the East African region during the solar minimum period 2008-2009
(Maseno University, 2023)In the electron density distribution at the low-latitude ionosphere, equatorial electrodynamics plays a critical role such as forecasting the dynamics and fluctuations of ionospheric plasma densities. The equatorial ... -
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 ... -
Correlations between schistosoma mansoni-specific immunoglobulins (igg1, igg2, igg3, igm), infection intensity and age among school pupils in Asembo area, western Kenya.
(Maseno University, 2017)ABSTRACT Schistosoma mansoni is a blood parasite that is common among school going pupils living near water bodies. It causes a disease known as schistosomiasis or bilhaziasis. Infected pupils stand higher risks of ... -
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 ... -
Determination of Antimicrobial Resistance of Escherichia Coli Isolated From Rastrineobola Argentea and Water Samples From Lake Victoria - Kenya
(Maseno University, 2014)Many strains of Escherichia coli can be pathogenic leading to diarrheal diseases. The occurrence of antimicrobial resistant bacteria is increasing in aquatic environments infecting fish which are later consumed by humans ... -
Determination of effective combinations of selected local materials for treatment of borehole water and to compare their effeciency with municipal water treatment technology
(Maseno University, 2016)Use of contaminated water risks human lives hence should be treated to meet drinking water quality guidelines. The most applied technique is municipal water treatment technology (MWTT) though inaccessible in peri-urban/rural ... -
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 ... -
Dissipation Rate of Chlorpirifos Within Mosquito Larvae Habitats In Maseno and its Activity Against the Larvae Relative to Dichlorodiphenyltrichloroethane
(Maseno University, 2016)ABSTRACT Despite more than a century of efforts to eradicate and control malaria, it still remains a major risk to public health and economies of countries in the tropical and subtropical regions of the world. Control of ... -
