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 ...
Projected Climatic and Hydrologic Changes to Lake Victoria Basin Rivers under Three RCP Emission Scenarios for 2015–2100 and Impacts on the Water Sector
(MDPI, 2019-07-13)
Abstract: Rivers in the Lake Victoria Basin support a multitude of ecosystem services, and the
economies of the riparian countries (Kenya, Tanzania, Uganda, Rwanda, and Burundi) rely on their
discharge, but projections ...
On Comparison of Local Polynomial Regression Estimators for P=0 and P=1 in a model based framework
(Canadian Center of Science and Education, 2018-07)
This article discusses the local polynomial regression estimator for P=0 and the local polynomial regression estimator for P=1 in a finite population. The performance criterion exploited in this study focuses on the ...
A mixed model approach to vegetation condition prediction using artificial neural networks (ANN): case of Kenya’s Operational Drought Monitoring
(MDPI, 2019-05-08)
Droughts, with their increasing frequency of occurrence, especially in the Greater Horn of Africa (GHA), continue to negatively affect lives and livelihoods. For example, the 2011 drought in East Africa caused massive ...
Implications of a Late-Time Interaction in Vacuum Dark Energy Models
(Africa Journal of Physical Sciences, 2019-02-28)
Recently, Wang et al. (2014) and Salvatelli et al. (2014) have reported results showing that a late-time interaction between cold dark matter (CDM) and vacuum dark energy is favoured by current cosmological datasets and ...
Aflatoxin-producing fungi associated with pre-harvest maize contamination in Uganda.
(University of Nairobi, 2020)
Maize is an important staple crop for the majority of the population in Uganda. However, in tropical and subtropical climates, maize is frequently contaminated with aflatoxins, a group of cancer-causing and immuno-suppressive ...
Zoonotic Pathogen Seroprevalence in Cattle in a Wildlife-Livestock Interface, Kenya.
(University of Nairobi, 2019)
A cross-sectional study was conducted to determine the seroprevalence of Brucella spp. and Leptospira spp. and risk factors of exposure in cattle in three zones with varying land use types and wildlife-livestock interactions. ...
Insights into malaria transmission among Anopheles funestus mosquitoes, Kenya.
(BMC, 2018-11-06)
Most malaria vectors belong to species complexes. Sibling species often exhibit divergent behaviors dictating the measures that can be deployed effectively in their control. Despite the importance of the Anopheles funestus ...
Cytotoxicity Of Fagaramide Derivative And Canthin-6-one From Zanthoxylum (Rutaceae) Species Against Multidrug Resistant Leukemia Cells
(University of Nairobi, 2019)
In our continuous search for cytotoxic compounds from the genus Zanthoxylum, chromatographic separation of the MeOH/CH2Cl2 (1:1) extract of Z. chalybeum yielded one new alkamide; 4-(isoprenyloxy)-3-methoxy-3,4-deoxymethy ...
