Geophysical characterization of the lithology and structure of the Olobanita Well Field, Lower Lake Baringo Basin, Kenya Rift: Implication on Groundwater occurrence
(University of NairobiGeology, 2010)The task of the research project is the use of geophysical technologies for the characterization of the lithology and structure beneath the Olobanita well field, and determine their implications on the groundwater drilling ... -
Aquifer stratigraphy and hydrogeochemistry of the lake nakuru basin, central kenya rift
(University of NairobiGeology, 2010)The geology of Nakuru area comprises mainly of volcanic soils and rocks (lava and pyroclastics) of Tertiary – Quaternary age, which has been affected by a series of faulting, and are overlain by recent sediments. This ... -
Amagnetic study of the shallow structure in the olobanita wellfield lower baringo basin, kenya rift: implication on the hydrogeology of the basin
(University of NairobiGeology, 2010)This study focuses on the application of the magnetic method as a mapping tool for determining the depth of volcano-sedimentary formations and detection of subsurface structural features in Olobanita wellfield basin, ... -
Subsurface structures and characterization of the silali geothermal system, kenya rift.
(University of NairobiGeology, 2011)Electrical resistivity methods are widely applied in geothermal exploration and are the cheapest means of acquiring subsurface data. Further detailed surveys like exploratory drilling which is cost intensive in an area ... -
Potential effects of changes in climate, land cover and population on the quantity of ater resources in lake nakuru and lake elmenteita areas, kenya
(University of NairobiGeology, 2011)This study evaluates the potential effects of changes in climate, population and land cover on the quantity of surface water and groundwater resources in Lake Nakuru and Lake Elmenteita areas. Multiple linear regression ... -
Geophysical mapping of buried river channels and other shallow structures recharging major aquifers in the lake Nakuru basin, Kenya rift: case study from Kabatini aquifer.
(University of NairobiGeology, 2010)The project covered the geophysical mapping of buried river channels and other shallow structures recharging major aquifers in the upper Nakuru basin of Kenya rift and in particular the Kabatini area. The project aimed ... -
Antiplasmodial Quinonesfrom Pentaslongiflora and Pentas lanceolata
(Chemistry, 2012-01)The dichloromethane/methanol (1:1) extracts of the roots of Pentas longiflora and Pentas lanceolata showed low micromolar (IC50=0.9–3µg/mL) in vitro antiplasmodial activity against chloroquineresistant (W2) and ... -
Expression analysis by quantitative real time polymerase chain reaction of genes for ssociation with resistance to hiv-1 infection in highly exposed uninfected commercial ex workers in the pumwani sex worker cohort
(University of NairobiCentre for Biotechnology and Bioinformatics, 2008)Altered susceptibility to HIV-1 infection has been observed in multiple cohort studies especially in highly exposed commercial sex workers. Host genetic factors have a major impact on the pathology of infectious diseases ... -
Comparative factors that influence landslide occurrence: application of gis and rainfall thresholds in landslide assessment in kenya
(University of NairobiGeology, 2011)Landslides are recurrent phenomena in Murang’a and Mt. Elgon Districts, causing loss of lives, property and fertile farmland. Despite the grievous danger posed, comparative studies of landslides in the two districts have ... -
Integration of remote sensing (RS) and geographic information system (GIS) in monitoring and management of floods; case study Budalangi area
(University of NairobiGeology, 2011)Flooding problem in Budalangi has been there for quite a long time. The flooding poses a major challenge to the riparian communities as well as the Kenyan Government and these calls for a solution to this problem as it ... -
