Fish Species Composition and Diversity of Small Riverine Ecosystems in the Lake Victoria Basin, Kenya
(2016)Riverine ecosystems in the Lake Victoria Basin (LVB) significantly contribute to the lake’s water budget and aquatic biodiversity. Despite their significance to the lakes fisheries, only limited biodiversity studies have ... -
Effects of irrigated and rain fed conditions on infestation levels of thrips (Thysanoptera: Thripidae) infesting Dolichos lablab (L.) in Eastern Kenya
(2016)Dolichos lablab (L.) is a neglected crop species in Kenya, grown only for subsistence where they are highly adapted to a small range of ecological niches. It is grown under irrigation and rain fed conditions, where ... -
Data Mining Model for Predicting Student Enrolment in STEM Courses in Higher Education Institutions
(2016-11-11)Educational data mining is the process of applying data mining tools and techniques to analyze data at educational institutions. In this paper, educational data mining was used to predict enrollment of students in Science, ... -
Analytic solution of a nonlinear Black-Scholes partial differential equation
(2016)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of a feedback effect. This is an illiquid mar- ket effect arising from transaction costs. An analytic solution to the ... -
A particular solution of a nonlinear black-scholes partial differential equation
(2016)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of transaction costs that lead to market illiq- uidity. After reducing the equation into a nonlinear parabolic porous ... -
On Singular Cauchy Problem of Euler-Poisson- Darboux Equation
(2016)We solve the singular Cauchy problem of Euler-Poisson-Darboux equation. The Riemann function, a solution corresponding to the adjoint equation is calculated and it enables us to evaluate any solution at a point by the ... -
Interrogating alkyl and arylalkylpolyamino (bis)urea and (bis)thiourea isosteres as potent antimalarial chemotypes against multiple lifecycle forms of Plasmodium falciparum parasites
(2016)A new series of potent potent aryl/alkylated (bis)urea- and (bis)thiourea polyamine analogues were synthesized and evaluated in vitro for their antiplasmodial activity. Altering the carbon backbone and terminal substituents ... -
Antiplasmodial activity, in vivo pharmacokinetics and anti‑malarial efficacy evaluation of hydroxypyridinone hybrids in a mouse model
(2016)During the erythrocytic stage in humans, malaria parasites digest haemoglobin of the host cell, and the toxic haem moiety crystallizes into haemozoin. Chloroquine acts by forming toxic complexes with haem molecules and ... -
Analytic solution of a nonlinear Black-Scholes equation
(2016)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of transaction costs that lead to market illiq- uidity. After reducing the equation into a nonlinear parabolic porous ... -
Analytic solution of a nonlinear Black-Scholes equation with price slippage
(2016)We study a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of transaction cost and a price slippage impact that lead to market illiquidity with feedback effects. After reducing the ... -
A put option's value for a nonlinear black-scholes equation
(2016)We study a nonlinear Black-Scholes partial differential equation for modelling illiquid markets with feedback effects. After reducing the equation into a second-order nonlinear partial differential equation, we find that ... -
Synthesis, Reactivity and Stability of Aryl Halide Protecting Groups towards Di-Substituted Pyridines
(2016)This paper reports the synthesis and reactivity of different Benzyl derivative protecting groups. The synthesis and stability of Benzyl halides, 4-methoxybenzyl halides, 3,5-dimethoxybenzyl halides, 3,4-dimethoxybenzyl ... -
The black-Scholes formula and the Greek parameters for a nonlinear Black-Scholes equation
(2016)We study the Greek (risk) parameters of a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of transaction costs. These parameters are derived from the Black-Scholes formula of the ... -
Greek parameters of nonlinear Black-Scholes equation
(2016)Derivatives are used in hedging European options against risks. The partial derivatives of the solution to either a variable or a parameter in the Black-Scholes model are called risk (Greek) parameters or simply the ... -
Climate change and tourism adaptation: Literature review
(2015)Purpose – This paper reviews published English literature on tourism adaptation to climate change. Climate change remains a challenge in the 21st centaury and beyond. Climate sensitive industries like tourism are vulnerable ... -
Adoption of green marketing practises by hotels in Mombasa County, Kenya
(2015)This study examined adoption of green marketing practises by hotels in Mombasa County, Kenya. To better understand this subject, the study sought to achieve three specific objectives; to determine the drivers for adoption ... -
An enhanced framework for regional tourism sustainable Adaptation to climate change
(2014)Tourismis not only contributing to climate change but also vulnerable to risks induced by changing climate regime. Sea level rise, extreme events, loss of biodiversity, water stress among other direct and indirect impacts ... -
Climate Change Impact Representation In Kenya's News Media
(2014)Today the questions of adaptation and mitigation to climate change risks are arching their way out to community platforms in an interpretive flow through various communication modes that shape public opinion and mediate ... -
Climate change-perceived impacts, risks, vulnerability, and response strategies: A case study of Mombasa coastal tourism, Kenya
(2015)Climate change policies are advancing, at least rhetorically. These policies are made through complex processes of interactions among stakeholders whose opinions are shaped by historical experiences, beliefs, awareness ... -
Tourism adaptation to climate change in the lenses of sustainability: Sustainable-adaptation
(2015)Climate change is considered one of the greatest challenges for humanity in the 21st century and beyond. Climate sensitive industries including tourism are vulnerable. In efforts to counter climate change, mitigation ...
