THE EFFECTS OF MARKET INTELLIGENCE SYSTEMS ON SALES REVENUE AMONG FRENCH BEAN PRODUCERS: A CASE STUDY OF OL-DONYO SABUK, MACHAKOS COUNTY, KENYA
(2016)Businesses operate in a world in which information is more readily and publicly available than ever before. Thanks to the development of the Internet, information on market trends, legislation, customers, suppliers, ... -
Magnetic Concentration of Iron in Lateritic Soils from Kamahuha, Murang’a County, in Kenya using Carbon Monoxide Generated In-Situ
(2014)Chemical and Mineral Analyses of laterites from selected sites in Kamahuha area of Murang’a County, in the Republic of Kenya, have been carried out with particular interest in the levels of iron and the type of minerals ... -
Beneficiation of Iron in Thermal-Reduced Ilmenite by Magnetic Separation
(2013)Increasing demands for Iron in countries development, and lack of conventional reducing agents has resulted into sourcing of alternative ways of beneficiating the iron ore. This paper reports on the study that was done to ... -
IJSET@2014 Page 707 Effects of Temperature on Ilmenite During Concentration of Iron in Laterites Using Charcoal and Separation using Magnetic Separation
(2014)Effect of temperature on ilmenite minerals found in laterites has been investigated. It was found that during reduction of iron minerals in laterites to magnetite using charcoal at temperatures of about 500-700oC, ilmenite ... -
Interrogating alkyl and arylalkylpolyamino (bis)urea and (bis)thiourea isosteres as potent antimalarial chemotypes against multiple lifecycle forms of Plasmodium falciparum parasites.
(2015)Abstract 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 ... -
Antiplasmodial flavonoids from Erythrina sacleuxii.
(2005)Abstract The acetone extracts of the root bark and stem bark of Erythrina sacleuxii showed antiplasmodial activities against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium falciparum. ... -
Antiplasmodial activity, in vivo pharmacokinetics and anti-malarial efficacy evaluation of hydroxypyridinone..
(2015)Background: 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 ... -
Interrogating alkyl and arylalkylpolyamino (bis)urea and (bis)thiourea isosteres as potent antimalarial chemotypes against multiple lifecycle forms of Plasmodium falciparum parasites
(Elsevier, 2015)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
(Dambuza et al. Malar J, 2015)Background: 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 ... -
Antiplasmodial Flavonoids from Erythrina sacleuxii
(Planta Med, 2006)The acetone extracts of the root bark and stem of Erythrina sacleuxii showed antiplasmodial activities against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium falciparum. Chromatographic ... -
Synthesis, Antiplasmodial Activity, and β‑Hematin Inhibition of Hydroxypyridone−Chloroquine Hybrids
(American Chemical Society, 2013)A series of noncytotoxic 4-aminoquinoline-3-hydroxypyridin- 4-one hybrids were synthesized on the basis of a synergistic in vitro combination of a precursor N-alkyl-3-hydroxypyridin-4-one with chloroquine (CQ) and tested ... -

FACTORIZATION OF LARGE COMPOSITE INTEGER
(International Journal of Mathematics and Statistics Studies, 2013)In this paper we practically deal with the problem of factorizing large integers. The various algorithms that have been proposed are not efficient that is they do not run in polynomial time. We use the algebraic approach ... -
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 ... -
