Approaches for Understanding Pastoral Response to Drought and Famine in Sub-Saharan Africa
(2016)Drought and famine in Sub-Saharan Africa is among the leading contributory causes of vulnerability in pastoral communities. This paper discusses approaches that allow understanding of pastoral indigenous adaptive ... -
Food Insecurity in Turkana District, Kenya: A Focus on the Impact of Colonial Rule
(2016)This paper examines the contribution of colonial rule to food insecurity among Turkana pastoralists living in the Turkana District in the arid zone of north-western Kenya. It is argued that food insecurity in Turkana ... -
Treatment of flower farm wastewater effluents using constructed wetlands in lake Naivasha, Kenya
(2016)Lake Naivasha, Kenya, is a fresh water lake currently experiencing severe environmental problems as result of pollution from agricultural effluents and urban water surface runoff, uncontrolled water abstraction, improper ... -
TOWARDS A NATIONAL POLICY ON WASTEWATER REUSE IN KENYA
(2016)Kenya is a water-scarce country with the capital city, Nairobi, receiving less than 100 l/capita/day. Potable water for irrigation and industrial use is generally unavailable, and this calls for alternative water sources. ... -
PHYSICOCHEMICAL CHARACTERISTICS OF UNDRAINABLE WATER DAMS UTILIZED FOR FISH REARING IN THE SEMI-ARID NAROMORU AREA, CENTRAL KENYA
(2016)Naromoru is a semiarid area in Central Kenya, occurring on the leeward side of Mt. Kenya. Its water sources include a few permanent rivers such as Nairobi River, intermittent streams and a large number of undrainable ... -
INFLUENCE OF LARGE WOODY DEBRIS ACCUMULATIONS ON MACROINVERTEBRATE DISTRIBUTION IN A LOW ORDER FORESTED TROPICAL STREAM, SAGANA RIVER, KENYA
(2016)Woody debris accumulations are important ecological components in low order forested streams. They provide forage and refuge for a macroinvertebrates, which are key trophic components for riverine fish. The occurrence ... -
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 ...
