Influence of Perception and Quality of ICT‐Based Agricultural Input Information on Use of ICTs by Farmers in Developing Countries: Case of Sikasso in Mali
(University of Nairobi, 2017)
Small-scale cereal farmers dominate agricultural activities in developing countries. These agricultural activities are characterized by low productivity due to lack of agricultural input information. ...
Effects of Tio2 Film Thickness and Electrolyte Concentration on Photovoltaic Performance of Dye-sensitized Solar Cell
(University of Nairobi, 2017)
Effects of film thickness and electrolyte concentration on the photovoltaic performance of TiO2-based dye-sensitized solar cell (DSSC) were studied. Nanocrystalline anatase TiO2 thin films with varying thicknesses (3.2–18.9μm) ...

The Sensitivity of East African rift lakes to climate fluctuations
(2010)
Sequences of paleo-shorelines and the deposits of rift lakes are used to reconstruct past climate changes in East Africa. These recorders of hydrological changes in the Rift Valley indicate extreme lake-level variations ...
Future hydrology and climate in the River Nile basin
(2011)
A critical discussion of recent studies that analysed the effects of climate change on the water resources of the River Nile Basin (RNB) is presented. First, current water-related issues on the RNB showing the particular ...
