Lie Symmetry Analysis of Modified Diffusive Predator-prey Competition System of Equations
(International Journal Of Multidisciplinary Sciences And Engineering, 2020-03)The predator-prey equations were developed and used by Lotka and Volterra to analyze the dynamics of biological systems in which two species interact, one as a predator and the other as prey [3]. Several attempts have been ... -
Use of Infinitesimal Transformations in obtaining the Generator of a harmonic fourth order non-linear ordinary differential equation.
(International Journal of Engineering& Scientific Research, 2017-05-05)Lie group Theory is applied to differential equations occurring as mathematical models [4]. This paper seeks to obtain a generator T for a harmonic fourth order non-linear ordinary differential equation using the Lie ... -
Integrated Approach to Wetland Protection: A Sure Means for Sustainable Water Supply to Local Communities of Nyando Basin, Kenya
(The International Journal of Engineering and Science (IJES), 2017)Wetlands have a buffering role particularly the ones at the lake shore, functioning like living filters by removing dissolved and suspended pollutants, thereby contributing to keeping lake waters clean and clear. They also ... -

(Trends in Phytochemical Research (TPR), 2018-09-27)The plant species Lonchocarpus eriocalyx Harms (Fabaceae) is a deciduous slender tree or shrub which grows up to 15 m tall. It is an important medicinal plant in Kenya used to treat a wide range of ailments including eye ... -
Preparation, characterization, and optimization of primaquine-loaded solid lipid nanoparticles
(International Journal of nanomedicine, 2014-08-11)Primaquine (PQ) is one of the most widely used antimalarial drugs and is the only available drug that combats the relapsing form of malaria. PQ use in higher doses is limited by severe tissue toxicity including hematological- ... -
Lonchocarpus eriocalyx (Harms) Herb Extract for Use as Painkillers
(Science Publishing Group, 2020-02-19)Today, many herbal preparations are being prescribed as analgesics. In the past decade, there has been a resurgence of interest in traditional systems of medicine which has become a topic of global interest. Indeed, many ... -
Estimation of market volatility-A case of logistic brownian motion
(International Journals of Marketing and Technology, 6/29/2013)In this paper, we have used the Dupire's equation to derive the volatility model when the asset price follows logistic Brownian motion. We have used the analysis of Brownian motion, logistic Brownian motion, derivation of ... -
Conditions for Positivity of Operators in Non-unital C*-algebras
(International Journal of Mathematical Analysis, 1/9/2015)In this paper, we present results on the necessary and sufficient condi-tions for positivity of operators in non-unital C*- algebras -
Characterization of Norm-Attainable Operators
(International Journal of Mathematical Archive, 7/13/2018)In this paper we characterize norm-attainable elementary operators, we show that 𝛿 𝑃,𝑄 is norm-attainable if both P and Q are norm-attainable and𝛿𝑃,𝑄 is norm-attainable 𝛿𝑃,𝑄if is normally represented. -
On Compact Operators Whose Norms Are Eigenvalues and Completeness
(International Journal of Contemporary Mathematical Sciences, 2/21/2018)Let X be a Banach space and T: X→Y be a linear operator, then Tis compact if it maps bounded sequences in X to sequences in Y with convergent subsequences, that is, if xn ∈ X is a bounded sequence, then T xn ∈ Y has a ... -
On denseness of similarity orbits of norm-attainable operators
(International Journal of Advances in Applied Mathematics and Mechanics, 4/16/2019)The notion of dense sets has been extensively discussed on both metric and topological spaces. Various properties of the sets have been proved under the underlying spaces. However, if we consider these sets to be from ... -
