(FACT Limited, 2009)Objective: Competition for land use among crops in the Nzoia and Mumias sugar belts hastened to favour sugarcane and maize at the expense of indigenous food crops such as onions, tomatoes, cassava and sweet ... -
Enhancing production through optimisation of DPPH and radical scavenging activity of grape seed extracts
(African Crop Science Society (Uganda), 2014)Polyphenols are important for their pharmacological activity and positive contribution to cellular processes within the body. They have the capacity to protect against oxidation of High Density Lipids (HDL) and, thus help ... -
Evaluation of Kenyan Bentonite Clay as Geothermal Well Drilling Mud
(2015)The quest for the development of geothermal plants with capacities up to 10,000 MWe in Kenya has recently placed greater demand on bentonite clay. Bentonite clay is at present largely imported into the country at the ... -
Evaluation of Solar-Energy Dryer Systems on Drying Behaviour and Quality Attributes of Amaranth Grains
(Science and Engineering Publishing Company, 2012)This work aimed at evaluating the thin layer drying behaviour of amaranth grains (Amaranthus cruentus) and comparing the quality of the grains dried under solar-energy tent dryer systems and the open sun. The dryers were ... -
Evaluation of the antimicrobial and antioxidant properties of extracts of Mondia whytei roots extracts
(Galati University Press, 2011)Extracts of Mondia whytei (M. whytei) root barks were screened for their inhibitory effects against Staphylococcus aureus (S. aureus) (ATCC 25923), Escherichia coli (E. coli) 0157:H7 (PSSCMI 0032), ... -
An experimental prototype for low head small hydro power generation using hydram
(2013)The global rise in energy demand has resulted to the over exploitation of both renewable and non renewable energy sources. Most feasible hydroelectric power (HEP) plants sites have been exploited and the current ... -
