Spatial distribution and temporal trend in concentration of carbofuran, diazinon and chlorpyrifos ethyl residues in sediment and water in Lake Naivasha, Kenya
(Springer, 2012)
Chlorpyrifos ethyl was found to be widely distributed in water and sediment in Lake Naivasha. Higher
levels were reported in sediment (11.2–30.0 ng g-1 dry
weight (dw) in wet season than in dry season (4.7–17.4 ng
g-1 ...
Mathematical modelling of wind turbine in a wind energy conversion system: Power coefficient analysis
(2012-01)
The world is increasingly going green in its energy use. Wind power is a green renewable source of energy that can compete effectively with fossil fuel as a generator of power in the electricity market. For this effective ...
Numerical solutions of the Burgers’ system in two dimensions under varied initial and boundary conditions
(2012)
In this paper, we generate varied sets of exact initial and Dirichlet boundary conditions for the 2-D Burgers’ equations from general analytical solutions via Hopf-Cole transformation and separation of variables. These ...
Steady MHD poiseuille flow between two infinite parallel porous plates in an inclined magnetic field
(2012)
In this paper, we examine the motion of a two dimensional steady flow of a viscous, electrically conducting, incompressible fluid flowing between two infinite parallel porous plates under the influence of transverse magnetic ...
Effects of sugarcane farming on diversity of vegetable crops in Mumias Division, Western Kenya
(Academic Journals, 2012-10-31)
Sugarcane farming is a commercial monocultural land use practice which often lead to reduction in agrobiodiversity. The study was carried out in Mumias Division of Western Kenya where 68% of the land is under commercial ...
Allelopathic effects of Mexican sunflower [Tithonia diversifolia (Hemsl) A. Gray] on germination and growth of Spiderplant
(2012)
Allelopathy refers to both beneficial and harmful effects of one plant on another plant by the release of chemicals from plant parts through leaching, root exudation, volatilization, residue decomposition and other processes ...
AN INVESTIGATION OF THE EFFECTS OF BOUNDARY LAYER THICKNESS ON A THIN FILM OF LIQUID FLOW DOWN AN INCLINED PLANE
(2012-12-30)
The motion of fluid substances may be described by the Navier-Stokes (N-S)
equations. The equations arise from the application of Newton’s second Law of
motion to a fluid. In this paper, N-S equations in two dimensions ...
Interactive effects of livestock and trees on nutrients and herbaceous layer production in a humid Kenyan savanna
(East African Journal of Science and Technology,, 2012)
Savannas are key ecosystems that provide vital services such as fodder for wild and
domestic animals, recreation, biodiversity habitats, CO2 sequestration and timber. Their
characteristics and distribution make them ...
Effects of Production Locations and Plucking Intervals on Clonal Tea Fatty Acids Levels in the Kenya Higlands
(J-STAGE, 2012-05-01)
Tea leaves contain unsaturated fatty acids which are precursors of aroma compounds. Despite uniform plucking practices in Kenya, plain black tea quality varies with locations. Variations in tea aroma
and/or precursors ...
Reproduction Inhibition Effects of Neem Products on the Larger Grain Borer (Prostephanus truncatus) (HORN) in Stored Maize Grains
(Egerton Journal of Science & Technology, 2012-12-07)
The larger grain borer (LGB), Prostephanus truncatus (HORN), has become one of the most important insect pest of stored maize in tropical Africa where it was introduced in the early 1980s. It has the major effect of seriously ...
