Factors Influencing Smallholder Farmers’ Adaptation to Climate Variability in Kitui County, Kenya
(Juniper Publishers, 2018-02)The study was carried out to examine the factors and constraints that influence small farmers’ adaptation to climate variability in Kitui County. Descriptive survey design was used. Two villages, Kaveta and Mikuyuni, were ... -
Financial Literacy and Retirement Planning in the Informal Sector in Kenya
(2014)Old age dependency has become a major issue of concern to governments today. This is because a large number of retirees lack any form of regular income to sustain them in retirement. Kenya has one of the highest levels ... -
Foreign Exchange Derivative Pricing with Stochastic Correlation
(Scientific Research Publishing, 2016)Financial markets are known to be far from deterministic but stochastic and hence time dependent correlation tends to suit the markets. We price for European Options by using three dimensional assets under stochastic ... -
A Fumonisins Immunosensor Based on Polyanilino-Carbon Nanotubes Doped with Palladium Telluride Quantum Dots
(2014-12-24)An impedimetric immunosensor for fumonisins was developed based on poly(2,5-dimethoxyaniline)-multi-wall carbon nanotubes doped with palladium telluride quantum dots onto a glassy carbon surface. The composite was assembled ... -
Genetic and morphological analyses indicate high population mixing in the endangered cichlid Alcolapia flock of East Africa
(2013)Alcolapia is a minor genus of small-bodied, polymorphic cichlids inhabiting the lagoons and hot springs surrounding the soda lakes Natron (largely in Tanzania) and Magadi (Kenya). Three Alcolapia species are present at ... -
Glossina pallidipes and host interactions: implications of host preference on transmission risk of Rhodesian sleeping sickness in Kenya
(2007)Host preference by tsetse flies, tsetse-host interaction and host diversity and abundance were evaluated in relation to transmission risk of rhodesian sleeping sickness in two tsetse subpopulations in Kenya. Bovidae provided ... -
“God Didn’t Make a Mistake in Creating Me”: Intrapersonal Resilience Processes among Gay and Bisexual Male Youth in Kenya
(MDPI, 2021)Gay and bisexual male youth in Kenya experience human rights violations, including pervasive stigma and discrimination, and these oppressive forces are associated with elevated rates of mental health concerns. Despite ... -
Graphenated tantalum (IV) oxide and poly (4-styrene sulphonic acid)-doped polyaniline nanocomposite as cathode material in an electrochemical capacitor
(Pergamon, 2014)Nanostructured poly(4-styrene sulphonic acid) and tantalum (IV) oxide-doped polyaniline nanocomposite were synthesised and their electro-conductive properties were determined. The oxide was synthesized using a modified ... -

Green Remediation of Carbamazepine from Water Using Novel Magnetic Iron Modified Carbonized Baggasse: Kinetics, Equilibrium and Mechanistic Studies
(SCIENCE DOMAIN, 2017-03-15)Baggasse derived biochar magnetically modified with iron (α-Fe2O3-CBG) was fabricated, characterized and applied as a low-cost adsorbent for the removal of carbamazepine (CBZ), a pharmaceutically active compound which ... -
Green Remediation of Hexavalent Chromium Using Naturally Derived Flavonoids and Engineered Nanoparticles
(2014)Contaminated ground- and surface water supplies such as the municipalities, wells, lakes, and rivers exhibit various levels of contamination that can pose numerous health risks. The release of contaminants into the environment ... -
Growth performance and intestinal morphology of African catfish ( Clarias gariepinus , Burchell, 1822) larvae fed on live and dry feeds
(2018)Effects of live and dry feeds on intestinal morphology and growth of African catfish, Clarias gariepinus, larvae (Burchell, 1822) were investigated from 2 days post hatching (dph) to 6 dph and 11 dph, respectively. Feeding ... -
Growth performance of Nile Tilapia (Oreochromis niloticus) fi ngerlings fed with water spinach (Ipomoea aquatica) diets
(Ann Mar Sci., 2022-04)Nile tilapia (Oreochromis niloticus) are herbivores with longer coiled intestines compared to carnivores; mouth characteristics necessary for plant shredding. Hence, several studies have been conducted to replace feed ... -
