Antinociceptive and antiplasmodial activities of cassane furanoditerpenes from Caesalpinia volkensii H. root bark
(Elsevier, 2012-01-01)
The chloroform and ethyl acetate extract (100mg/kg) of Caesalpinia volkensii H. exhibited
significant (P≤ 0.05) antinociceptive activities using hot plate and writhing tests in mice
while the later showed antiplasmodial ...
NaCl salinity affects germination, growth, physiology, and biochemistry of bambara groundnut
(Sociedade Brasileira de Fisiologia Vegetal, 2012-09)
The effects of NaCl salinity on seed germination, growth, physiology, and biochemistry of two bambara groundnut landraces (Vigna subterranea (L.) Verdc), Kakamega (white seed coat) and Mumias (red seed coat), were investigated ...
Quality and yields of black tea Camellia sinensis (L.) O. Kuntze responses to harvesting: A review on experiences from Kenya
(PBS Journals, 2012)
Tea beverages, from tender shoots of Camellia sinensis L., are the most widely consumed fluids after water. The young tender shoots of the plant are harvested using various plucking methods. Incorrect plucking leads to ...
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 ...
Changes in soil properties following conversion of forests into intensively managed Camellia sinensis L. plantations along a chronosequence.
(International Society of Tea Science, 2012)
Tea in Kenya was introduced in the beginning of the 20th Century, although commercial cultivation commenced in 1924. The total acreage of tea plantations has steadily increased and currently covers approx. 0.15 million ha, ...
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 ...
