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 ... -
Spectrophotometric Determination of Traces of Lead (II) in Spinach Samples Marketed in Chuka, Kenya
(2015-11-15)Three hydroxytriazenes were synthesized and studied for the spectrophotometric determination of Lead (II) in spinach samples. Lead (II) reacts with hydroxytriazenes to form a 1:2 yellow complex, having a sensitive absorption ... -
Activity concentrations of 40K, 232Th, 226Ra and radiation exposure levels in the Tabaka soapstone quarries of the Kisii Region, Kenya
(2015-11-18)A radiological study was carried out in the soapstone quarries of Tabaka region of Kisii district in the Southern Nyanza province, Kenya, where soapstone has been mined and used as a carving medium for hundreds of years. ... -
Advances in composite integer factorization
(2015-11-18)In this research we propose a new method of integer factorization. Prime numbers are the building blocks of arithmetic. At the moment there are no efficient methods (algorithms) known that will determine whether a given ...
