Modeling the Dynamics of Bacteremic Pneumonia: The role of Control Strategies, Case Detection and Treatment
(Maseno University, 2016)Pneumonia is a respiratory disease mainly caused by bacteria, Streptococcus Pneumoniae. The bacteria exist in up to 90 different strains out of which 25 are invasive. Pneumonia is one of the leading causes of mortality ... -
Zero Divisor Graphs of Classes of Completely Primary Finite Rings of Maximal Prime Power Characteristic
(Maseno University, 2017)It is well known that in a finite ring R, every element is either a zero divisor or a unit. The classification of finite rings is not fully settled. Different studies have generated interesting results on certain classes ... -

Characterization Of Scalar Type Operators
(Maseno University, 2017)A closed densely defined operator H, on a Banach space X, whose spectrum is contained in JR and satisfies the growth condition II (Z-H)-l II:::; CII~~:l Vz E iJR for some a ~ 0 and C > 0 is of (00,00+1) type R In studying ... -
Unsteady MHD heat and mass transfer over an infinite Porous flat plate with convective surface boundary Conditions
(Maseno University, 2018)Unsteady MHD heat and mass transfer over an infinite flat plate with convective surface boundary condition problems have received little attention yet they are of great importance in many scientific and engineering fields. ... -
Certain properties of essential Numerical ranges of bounded Operators on banach spaces
(Maseno University, 2018)Abstract The numerical range of an operator on a Hilbert space has been extensively researched on. The concept of numerical range of an operator goes back as early as 1918 when Toeplitz defined it as the field of values ... -
Construction of Zero Inflated Poisson Mixture Distributions and Application to Fertility Data
(Maseno University, 2018)In applications involving count data, it is common to encounter the frequency of observed zeros significantly higher than predicted by the model based on the standard parametric family of discrete distributions. In such ... -
Analysis of Heat and Mass Transfer Effects on Steady Buoyancy Driven Magnetohydrodynamics Fluid Flow Past an Inclined Infinite Flat Plate
(Maseno University, 2018)The phenomenon of natural convection arises in fluids when temperature change causes density variation leading to buoyancy forces acting on the fluid particles. Natural convection flows are frequently encountered in ... -
Health risk of toxic Cyanobacteria in drinking water in the Nyanza gulf water, Lake Victoria Kenya
(Maseno University, 2018)Cyanobacteria are single-celled algae that thrive in warm and nutrient rich water bodies including lakes. They can produce different kinds of toxins called cyanotoxins. Microcystin is the most common and most studied ... -
Determinants of mortality and survival time among HIV infected patients on antiretroviral therapy in Machakos county, Kenya
(Maseno University, 2019)ABSTRACT Human Immunodeficiency Virus (HIV) remains one of the world's most significant public health concerns. Anti-retroviral treatment (ART) is meant to suppress replication of the virus, consequently improving health ... -
Mathematical Modeling of Pesticide Adsorption In A Porous Medium; Convection-Dispersion Transport with Steady State Water Flow in Three Dimensions
(Maseno University, 2019)ABSTRACT The transport of solutes through porous media where chemicals undergo adsorption or change process on the surface of the porous materials has been a subject of research over years. Usage of pesticides has ... -
Stochastic Modeling of Bamboo Population Growth and Optimal Harvesting
(Maseno University, 2019)Population growth and harvest modeling is an active area of current research. There has been an effort to move from deterministic Ordinary Differential Equations (ODE) to Stochastic Differential Equations (SDE) modeling. ... -
On The Algebraic Numerical Range of the Basic Elementary Operator and Norm of a Generalized Derivation
(Maseno University, 2020)An elementary operator is a bounded linear map defined on the set of bounded linear operators acting on an infinite dimensional complex Hilbert space H. Various forms of elementary operators have been studied in the past ... -
