Effect of decomposition intensity of incorporated chickpea manure on stability and saturated hydraulic conductivity of a clay loam and clay soil
(Academic Journals, 2011-03-04)
The role of organic matter (OM) in soil aggregation and saturated hydraulic conductivity (Ksat) has long been recognised but their depedence on the intensity of decay is less studied. The objective of this study was to ...
Effect of Reduced Tillage and Mineral Fertilizer Application on Maize and Soybean Productivity
(2012)
Reduced tillage is said to be one of the potential ways to reverse land degradation and ultimately increase the productivity of degrading soils of Africa. We hypothesised that crop yield following a modest application of ...
Using Podcasts to Help Students Apply Informatics Concepts: Benefits and Unintended Consequences. CIN: Computers, Informatics Nursing
(2012-03)
Despite requirements for robust health informatics education, a multitude of educators and policy analysts report that programs are not adequately preparing nurses to handle the bevy of technologies that will be a part of ...
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, ...
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 ...
