molluscicidal and antimicrobial activity of solanum aculeastrum
(2003)
The methanolic extract of the fresh root bark and berries of Solanum aculeastrum showed significant activity against host snails of schistosomiasis. The berries extract was more potent with 100% snail kill at 50 ppm. ...
Bandwidth selection in smoothing functions
(2006)
A simple criterion for selecting a bandwidth parameter that controls the amount of smoothing in functions is described. The procedure is computationally inexpensive and, hence, worth
adopting. We argue that the bandwidth ...
Differential Induction of Proteins in Anopheles gambiae sensu stricto (Diptera: Cullicidae) Larvae in Response to Heavy Metal Selection
(National Institute of Health, 2010-07-21)
Investigations were conducted to establish the magnitude and pattern of differential expression of proteins due to generational selection of third instar An. gambiae s.s. larvae by cadmium, copper and lead heavy metals, ...
The Glossina proteolytic lectin (Gpl) gene is expressed only in members of Glossina species
(2008)
Differentiation of bloodstream-form trypanosomes into procyclics in tsetse flies
(Diptera: Glossinidae) is a crucial step in the establishment of midgut infections. A number
of factors have been implicated in the ...
Characterization of Uromyces appendiculatus isolates collected from snap bean growing areas in Kenya
(Academic Journals, 2012-11-02)
Bean rust (Uromyces appendiculatus (Pers.:Pers.) Unger var. appendiculatus) is one of the most devastating and variable pathogens of common bean (Phaseolus vulgaris L.) worldwide that can cause total crop loss. Characterization ...
Isolation and characterization of actinobacteria from Lake Magadi, Kenya
(Academic Journals, 2013-08-09)
Actinobacteria are ubiquitous and have been detected in terrestrial and aquatic ecosystems. Although, various studies have focused on the ecology of this phylum, data on the ecology of actinobacteria endemic to soda lakes ...
Investigating a Prototype Heat Exchanger for Steam Storage
(2014-07)
A coiled tube single pass counter flow heat exchanger was designed and fabricated using locally available materials and its capacity to transmit heat to water to make steam was tested. The heat exchanger was part of ...
New sources of resistance to spotted stem borer, Chilo partellus in sorghum
(2012)
The lepidopteran Chilo partellus Crambid, an introduced pest in East and southern Africa from Asia, is the most economically important stem borer species infesting cereals in Africa. Chilo partellus causes more than 40% ...
Effect of Bt cotton expressing Cry1Ac and Cry2Ab2 protein on soil nematode community assemblages in Mwea, Kenya
(2013)
Objective: The nematode community structure in soil cultivated with Bt cotton (containing
Cry1Ac and Cry2Ab2 protein), isoline (non Bt cotton) and HART 89M (non Bt cotton) was
evaluated in a field trial at Ndomba in the ...
Decomposition of Cassia siamea loppings in semiarid Machakos, Kenya
(1994)
The rate of decomposition of Cassia siamea Lam. prunings in an alley cropping system was investigated using litter bags in the semiarid area of the Machakos District, Kenya, during the short rains of 1988 and the long rains ...
