Effect of chemical spray on insect pests and yield quality of food grain legumes
(2008)
Phaseolus vulgaris L. var. GLP 2), the lima bean (Phaseolus lunatus L.), the green gram (Vigna radiate L.), the lablab (Lablab purpureus L.) and the chickpea (Cicer arietinum). The experimental design was a randomized ...
Kinetics of Copper Desorption from Regenerated Spent Bleaching Earth
(2009)
Recent studies have shown that spent bleaching earth (SBE), a clayey waste from edible oil refineries,
could be used to remove Cu from aqueous solutions. This could result in copper-laden material whose continual
disposal ...
Management of Fusarium head blight of wheat and deoxynivalenol accumulation using antagonistic microorganisms
(2008)
Laboratory and green house studies were conducted at the Faculty of Agriculture, University of Nairobi, to evaluate the efficacy of Epicoccum sp., Alternaria sp., Trichoderma sp. and Bacillus sp. in control of Fusarium ...
High-Level Heterologous Expression of Bacillus halodurans Putative Xylanase Xyn11A (BH0899) in Kluyveromyces lacti
(2007-03)
The putative xyn11A structural gene (BH0899) encoding a family-11 xylanase from alkaliphilic Bacillus halodurans strain C-125 was heterologously expressed in the yeast Kluyveromyces lactis CBS 1065 and secreted to a level ...
Cloud cover estimation over selected locations in East Africa using satellite derived reflectivity data
(2008)
The study aimed at improving the estimation of cloudiness over East
Africa through establishment of the relationship between observed
cloud cover and the satellite derived reflectivity. Two types of data
were used, ...
Soil moisture and maize-bean yields under different management in a six years old hedged Agroforestry system in Semi-Arid Laikipia, Kenya, for two contrasting seasons
(2007)
Hedged agroforestry (AF) demonstration plots with maize/bean intercrops were studied at Matanya in
Laikipia district, Kenya, between 1991 and 1995 inclusive, to understand crop yield behaviour due to
selected soil moisture ...
Preliminary reports on Radon Concentration in Drinking Water and Indoor Air in Kenya
(2002)
A screening survey has been carried out to determine activity concentrations of radon (222Rn) in drinking water and indoor air in various locations in Kenya. The concentration of 222Rn in water was measured using a liquid ...
On The Regular Polygons In The Chinese Checker Plane
(University of Nairobi, 2000)
In this paper, we define Chinese checker regular polygons, and determine which Euclidean regular polygons are also Chinese checker regular, and which are not. Finally, we study the problem of existence or nonexistence of ...
EFFECT OF NITRATION ON PRESSED TIO2 PHOTOELECTRODES FOR DYE-SENSITIZED SOLAR CELLS
(2007)
TiO2 films made by the pressing method and then nitrogen-doped by heat-treatment in
nitrogen, oxygen and argon gas mixture have been studied and the effects of structural characteristics,
optical and electrical properties ...
