Modeling co-infection of paediatric Malaria and Pneumonia
(Int. Journal of Math. Analysis, 2013)Malaria and persistent childhood diseases are a major threat to child survival in the developing world. In this paper, we develop and analyse a mathematical model for paediatric malaria and pneumonia co-infection. We ... -
Modeling Household Water Demands Using Sinusoidal Models
(International Journal of Statistics and Applied Mathematics, 2019)Household water in Kenya is used in agricultural activities, industrial activities and other uses. A lot of water is consumed by indoor appliances. The water management strategy affects the household demand for water. The ... -
Morphological, genetic and symbiotic characterization of root nodule bacteria isolated from Bambara groundnuts (Vigna subterraneaL. Verdc) from soils of Lake Victoria basin, western Kenya.
(Journal of Applied Biology and Biotechnology, 2015)Low soil nitrogen (N) is a major constraint for sustainable crop production in smallholder farming systems in Africa. Grain legumes such as bambara groundnuts (Vigna subterraneaL. Verdc). can form N fixing symbiotic ... -

(Journal of Natural Sciences Research, 2017)Herbal medicine has been used for many years and it remains widespread in developing countries while the use of complementary alternative medicine is increasing rapidly in developed countries. Senna didymobotrya is important ... -
Multiple Discriminantanalysis as Applied to language Distinction
(Bulletin of Mathematics and Statistics Research, 2018)This paper presents study on the application of multiple discriminant analysis (MDA) to distinguish between languages with a focus on five languages of the Coastal region of Kenya. Chapter one gives an introduction of the ... -
Negative Magnetization and Inverse Exchange Bias Effect Induced By Modulating the Relative Proportion of Mn in Gd 2 Co 2−Xmnxo6 Perovskites
(Physical Review, 2023-06-28)The magnetic properties of Gd 2 Co2−x Mnx O6 by modulating the relative proportion of Mn are experimentally investigated in this paper. The experimental results indicated that an intrinsic effect of negative magnetization ... -
New synthetic pathways for thiocarbohydrazide and salicylaldehyde azine compounds
(Asian Journal of Chemical Sciences, 2017)Thiocarbohydrazide synthesis is an important intermediate step for many hydrazine organic synthetic reactions. Synthesis of thiocarbohydrazide can be done by reaction of carbon disulfide with hydrazine (hydrazinolysis) ... -
Nonlinear H∞ Guidance Design for Missile against Maneuvering Target
(Science Domain, 2017-05-01)A new guidance law is derived for missile against maneuvering target by adopting nonlinear H∞ control theory. The guidance law is based on three dimension (3D) nonlinear kinematics described by modified polar ... -
Nonzero Lie Brackets of Third Order Nonlinear Ordinary Differential Equation
(ResearchGate, 2018-06)Lie symmetry analysis of Ordinary Differential Equation can be used to obtain exact solution of the equation of the form F (x, y, y’ y’’ y’’’) = 0. In this paper we use Lie Symmetry analysis approach to obtain the nonzero ... -
