Impacts of climate-induced changes on the distribution of pesticides residues in water and sediment of Lake Naivasha, Kenya
(Springer Netherlands, 2013-03-01)
This study reports evidence of increased chlorpyrifos contamination in sediment and water in Lake Naivasha following its intensive application in the horticultural farms in the catchment area. Analytical results show that ...
Effect of genotypes in different tea-growing locations in Kenya on some micronutrients content of black tea.
(International Society of Tea Science, 2013)
Human beings and plants require essential elements for normal physiological functions and survival. Tea beverages are the most widely consumed fluids after water. If the beverages have appreciable levels of micronutrients, ...
Influence of Location of Production, Season and Genotype on Caffeine and Flavan-3-ols in Young Green Tea (Camellia sinensis) Leaves in Kenya
(David Publishing Company, 2013)
Although tea is grown in agro-ecological regions widely varying in environmental factors affecting yield and quality, planters usually import genetic materials across the different growing regions assuming genotypes with ...
Archaeal diversity and community structure in the compartmented gut of highert termites
(Philipps-Universität Marburg, 2013)
Termites are phylogenetically divided into lower and higher termites (Inward et al., 2007). The higher termites, which constitute three quarter of all known termite species, are represented by only one family Termitidae, ...
MATHEMATICAL INVESTIGATION ON THE EFFECT OF NUMBER OF BRANCHES ON WATER HAMMER
(Pushpa Publishing House, 2013-10-01)
This paper looks at water hammer with an emphasis on the number of branches. The mathematics of water hammer are described in a transient condition. This includes the momentum and continuity equations for conduits. A ...
Modelling Stratified Flow in an Inclined Flow Channel with a Bend
(International Scientific Press, 2013-07-01)
Multi-phase flows modelling in wellbore has always been a problem to the petroleum and many other industries. In the petroleum industry, correlations are presently in use, most of which are obsolete as their application ...
On the Solution of Confined Aquifer Flow Equations: Finite Difference Approximations
(Hikari Ltd, 2013)
In general, groundwater flow in porous media on a microscopic level is three-dimensional. However, when considering regional flow problems ie groundwater flow on a macroscopic level, it is noted that because of the low ...
Weak Solution of the Singular Cauchy Problem of Euler-Poisson-Darboux Equation for n= 4
(2013)
We consider the singular Cauchy problem of Euler-Poisson-Darboux equation (EPD) of the form utt+ k t ut=∇ 2u u (x, 0)= f (x), ut (x, 0)= 0 where∇ 2 is the Laplacian operator in R n, n will refer to dimension and k a real ...
Factors affecting antenatal care attendance: results from qualitative studies in Ghana, Kenya and Malawi
(Public Library of Science, 2013-01-15)
Antenatal care (ANC) is a key strategy to improve maternal and infant health. However, survey data from subSaharan Africa indicate that women often only initiate ANC after the first trimester and do not achieve the ...
Qualitative analysis of phytoconstituents in tragia brevipes plant
(International Journal of Pharmaceutical Research & Analysis, 2013)
The study was conducted to analyze the phytoconstituents of Tragia brevipes plant leaves. The plant samples were
extracted using methanol and water in the ratio 9:1. The phytoconstituents study was done using standard ...
