Development of a Differential Normal Pulse Voltammetric Method for Phosphate Determination in Water
(University of Nairobi, 2023)
Determination of phosphate levels in water is important in assessing the quality of drinking water and remediation of phosphate in water sources. Visible spectrophotometry is the standard technique that has been used for ...
Analysis of Subtropical Anticyclones as Synoptic Controls of Seasonal Rainfall Extremes in East Africa
(University of Nairobi, 2023)
This study aims to investigate the influence of anticyclones adjacent to Africa on seasonal rainfall extremes over East Africa, focusing on the March to May (MAM) and October to December (OND) rainy seasons. Specific ...
Status of Copper Level and Effects of Rhizatech®tm Vesicular Arbuscular Mycorrhizal Fungi on Wheat Growth, Yield and Copper Ion Uptake in Narok North Sub-county, Kenya
(University of Nairobi, 2023)
Soil related abiotic factors hindering wheat production in wheat growing regions in East Africa include
poor soil fertility, pests, diseases, drought and salinity. Copper (Cu) deficiency has been identified in
soils in ...
Implications of Dietary Variation on Abundance and Occupancy Relationships in a Predominantly Muroid Small Mammal Community in Mpala Conservancy, Kenya
(University of Nairobi, 2023)
Positive interspecific relationship between abundance and occupancy (AOR) is among the most common patterns in ecology. This has been attributed to niche differences among species such that resource generalists are expected ...
Clay Derived Zeolites for Removal of Nitrates, Phosphates and Heavy Metals From Water
(University of Nairobi, 2023)
Access to clean and safe water for domestic and industrial use remains a significant challenge in developing countries of the Third World. In Kenya, safe drinking water is accessible to only 59% of the population. Multiple ...
