New compounds with antimicrobial activities from Elaeodendron buchananii stem bark
(Journal of Asian Natural Products Research, 2018)The plant species Elaeodendron buchananii Loes is widely used in folklore medicine to manage microbial infections in Kenya. Previous studies on the plant fruits and root bark revealed the presence of steroids and ... -
A new gnidiflavanone-flavonol dimer and other constituents from Gnidia apiculata
(Taylor & Francis, 2022)A new 3,800-flavanone-flavonol dimer gnidiflavanone-flavonol (1) and 10 known compounds (2–11), including four rare primula type flavones 2–5, were isolated from the roots of Gnidia apicu lata. Compounds 2–5 and 7 were ... -
The Nexus between Electoral Management System and Post-Election Violence in Kenya Since 1963
(African Journal of Empirical Research (AJERNET), 2024-10-08)The study investigates the relationship between Kenya's electoral management system and post-election violence, which has per sisted despite numerous reforms since the country's independence in 1963. The primary aim was ... -
Nitrogenous Fertilizer Rates and Plucking Intervals Effects on Soil Organic Carbon, pH and Tea Yields and Their Relationships in Eastern Africa Tea Growing Regions
(International Society of Tea Science, 2020)Eastern Africa tea grows in high rainfall areas where nutrients depletion through leaching, and surface run-off can be high, in addition to removal with crop. Nutrients replenishment through fertilizer applications is ... -

NPK (S) fertilizer use in commercially cultivated clone BBK 35 in different tea growing regions of Kenya: I. Experimental design and initial soil chemical properties.
(Tea Research Foundation of Kenya, 2008)An experiment was set up in five sites by superimposing on commercially grown plantations consisting of one popular tea cultivar, clone BBK 35 at Timbilil estate, Kericho; Changoi Estate, lower Kericho; Magura-Kipkebe ... -
NPK (S) fertilizer use in commercially cultivated clone BBK 35 in different tea growing regions of Kenya: II. Effects of nitrogen rates and plucking intervals on soil chemical …
(Tea Research Foundation of Kenya, 2008)One commercially and widely grown tea cultivar, clone BBK 35 was evaluated for changes in soil chemical properties at different N-fertilizer rates and plucking rounds in five different localities in Kenya. The soils in all ... -
Optimising fermentation time in black tea manufacture
(Elsevier, 1986)A comparative study using in-line theaflavins analysis (ILTF), theaflavins of made-tea analysis (TFMT) and tasters' evaluations, to optimise fermentation during tea manufacture, was carried out. All methods obeyed a quadratic ... -
Optimization of biodiesel synthesis from Jatropha curcas oil using kaolin derived zeolite Na–X as a catalyst
(Royal Society of Chemistry, 2022)Biodiesel is an alternative renewable green fuel obtainable from the reaction of plant or animal oil with a low molecular weight alcohol in the presence of a catalyst. However, the cost of its production remains high due ... -
Optimization of Bioethanol Production from Sweet Sorghum Stalk (Sorghum bicolor (l.) Moench) Juice Using Response Surface Method
(Science publishing group, 2022)The use of fossil fuel as a source of energy has been unsustainable and has adverse effects to the environment. Bioethanol is a suitable alternative due to its exceptional properties. Bioethanol production can be done ... -
Optimization of parameters for bio-ethanol production from sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice and finger millet malt using Taguchi method
(2024)Bio-ethanol is a promising renewable energy but its production is expensive from high cost of feedstocks. In this study, sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice was investigated for bio-ethanol production. ... -
Optimizing production of biodiesel catalysed by chemically tuned natural zeolites
(Elsevier, 2018-12-31)The twin crises of fossil fuel depletion and environmental degradation coupled with their unpredictable prices is a reality. Biodiesel is a promising, viable and environmentally friendly alternative. However, production ... -
Optimizing Zeolitic Catalysis for Environmental Remediation
(John Wiley & Sons, Inc., 2015-05-01)This chapter discusses the effects of chemical and physical properties of zeolites as they affect the catalytic efficacy and applications of the zeolites in environmental remediation. Heterogeneous catalysts, where zeolites ... -
