Effects of land-use intensification on distribution and diversity of Fusarium species in Machakos County, Kenya.
(University of Nairobi, 2015)Land-use intensification has a significant influence on occurrence of soil microorganisms. The effect of this phenomenon on Fusarium species is poorly characterized. One hundred soil samples were obtained from 3 replicated ... -
The effects of legume and maize stover residue management practices on the yield of a subsequent maize crop in Kitale, Kenya
(2015-06-13)A trial focusing on the management of Mucuna pruriens (mucuna) and maize stover residues was conducted over two seasons on a low fertility soil in the North Rift region of Kenya. The effects of factorial combinations of ... -
The effects of maternal and infant vitamin A supplementation on vitamin A status: a randomised trial in Kenya.
(2007)Postpartum vitamin A supplementation of mothers and infants is recommended, but the efficacy has been questioned. In this double-blind, placebo-controlled trial, Kenyan mother-infant pairs were randomised to maternal vitamin ... -
Effects of Medicinal Plant Extracts and Photosensitization on Aflatoxin Producing Aspergillus flavus (Raper and Fennell)
(University of Nairobi, 2017)This study was undertaken with an aim of exploring the effectiveness of medicinal plant extracts in the control of aflatoxin production. Antifungal properties, photosensitization, and phytochemical composition of aqueous ... -
The effects of Mn2+, Ni2+, Cu2+, Co2+ and Zn2+ ions on pesticide adsorption and mobility in a tropical soil.
(Department of Chemistry, 2009)The adsorption behaviour of DDT in a tropical silt-clay soil from Kenya showed that addition of increasing metal ion concentrations from 10 to 100 microg/g of soil, reduced the % DDT adsorption in the soil by factors ranging ... -
Effects of monocular deprivation on the dendritic features of retinal ganglion cells
(University of Nairobi, 2015)SUMMARY: Monocular deprivation results in anatomical changes in the visual cortex in favor of the non-deprived eye. Although the retina forms part of the visual pathway, there is scarcity of data on the effect of monocular ... -

(2014-04-28)The effects of oxygen partial pressure and substrate temperature 011 optical properties of CuCr02 thin films deposited on float glass substrate by reactive DC magnetron sputtering system using CuCr allov targets have ... -
The effects of paraffin oil on phototropic and geotropic responses in avena coleoptiles
(University of Nairobi, 1966)Experiments are described which were designed to test the significance of the coleoptile tip as the site of reception of light stimulus leading to negative photo-tropic response under paraffin oil. The results show clearly ... -
Effects Of Plant Structure On Butterfly Diversity In Mt. Marsabit Forest, Northern Kenya
(2010)Butterflies, like most forest dependent animals are good ecological indicators of the health of the forests they dwell. For example, butterfly species richness decreases after a forest disturbance and fragmentation but a ... -
Effects of prescribed seasonal burning on a comretum-commiphora plant community in south central Kenya
(Texas A and M University, USA, 1982)Studies of prescribed seasonal burning on a combretum-commiphora plant community were conducted in Kenya on the National Range Research Station, Kiboko, in 1980-81. Dry and early rainy season burns were applied in different ... -
Effects of Rainfall on Malaria Occurrences in Kenya
(University of Nairobi, 2015)In this paper, we analyze data on malaria prevalence in Kenya and investigate if there are incidences of malaria in areas formerly not prone to malaria infection. It is hoped that the findings of this study shall be used ... -
