(The American Society of Tropical Medicine and Hygiene, 2007-02-23)
Human co-infection with Plasmodium falciparum and helminths is ubiquitous throughout Africa, although its public health significance remains a topic for which there are many unknowns. In this review, we adopted an empirical ...
Biochemical differentiation in Camellia sinensis and its wild relatives as revealed by isozyme and catechin patterns
(Pergamon, 2002-12-10)
The variation in three NADP-linked dehydrogenase enzymes; glucose-6-phosphate dehydro- genase, 6-phosphogluconate dehydrogenase and shikimate dehydrogenase as well as alpha and beta esterases was determined in 24 cultivars ...
Response of tomato genotypes to induced salt stress
(African Crop Science Society, 2003-12-31)
Thirteen tomato (Lycopersicon esculentum L.) genotypes were subjected to salt treatment under hydroponics and their responses monitored in a set of two experiments with the objective of advancing them as potential salt ...
Polyploidy Breeding of African Nightshade ( Solanum section Solanum )
(Global Science Books, 2007)
The perception of African nightshades (
Solanum
section
Solanum
) as “healthy” foods, supported by documentation of their high nutri-
tional and medicinal benefits, has led to a sudden and ...
Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Global Science Books, 2009-01-21)
Solanum villosum is an important leafy vegetable in Kenya whose production faces low yields. Two potentially high leaf-yielding
genotypes of S. villosum, T-5 and an octoploid have been developed. Field experiments were ...
Combining evidence of natural selection with association analysis increases power to detect malaria-resistance variants
(The American Society of Human Genetics, 2007-08)
Statistical power to detect disease variants can be increased by weighting candidates by their evidence of natural selection. To demonstrate that this theoretical idea works in practice, we performed an association study ...
The effect of education on business skills cognition among informal sector entrepreneurs
(journal of Vocational Education and Training, 2003)
This study examined the effect of education, in comparison to training the experiential factors on
Business Skills Cognition. Business Skills Cognition was a quantitative dependent variable

Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Afr. J. Hort. Sci., 2009)
Seven tomato (Lycopersicon sp.) accessions were evaluated for their resistance to the tomato red spider mite, Tetranychus evansi Baker and Pritchard, in the laboratory. Data recorded was: (i) trichome density and (ii) ...

This study sought to find out the opinion of the head teachers on equity of the established criteria in bursary support for the needy. It was done in the District’s 27 secondary schools with the total student enrolment of ...
Effects of day-length and temperature on floral structure and fertility restoration in a season-dependent male-sterile Solanum villosum Mill. mutant
(Springer Verlag, 2007)
Solanum villosum is an important African leafy vegetable whose yield is limited mainly by competition from early and excess fruit-set. Induced male-sterility is a potential tool to reduce this competition and enhance yields. ...
