Measles, a highly contagious airborne disease, remains endemic in many developing countries with low vaccination coverage. In this paper, we present a deterministic mathematical compartmental model to analyze the dynamics of measles. We establish glo

Background: Adolescent girls are more likely to develop anemia as a result of physical and physiological changes that place a greater strain on their nutritional needs. Primary studies, on the other hand, may not be sufficient to provide a complete p

Measles is a highly contagious airborne disease that is endemic in many developing countries with low levels of vaccination coverage. In this paper, we propose a deterministic compartmental mathematical model for measles disease dynamics. We establis

MHD Partial Slip Flow and Heat Transfer of Nanofluids through a Porous Medium Over a Stretching Sheet with Convective Boundary Condition
Autor: Yohannes Yirga
Publikováno v: Momona Ethiopian Journal of Science. 12:39-59
This paper investigates the boundary layer analysis for magnetohydrodynamic partial slip flow and heat transfer of nanofluids through porous media over a stretching sheet with convective boundary condition. Four types of nanoparticles, namely copper,

Magnetohydrodynamic Flow of Viscous Fluid over a Non-Linearly Stretching Sheet
Autor: Yohannes Yirga, Daniel Tesfay
Publikováno v: OALib. :1-11
In this paper, the Magnetohydrodynamic (MHD) Flow of Viscous Fluid over a Nonlinear Stretching Sheet is investigated numerically. The partial differential equations governing the flow are reduced to a non linear ordinary differential equations by usi

Heat and Mass Transfer in MHD Flow of Nanofluids through a Porous Media Due to a Permeable Stretching Sheet with Viscous Dissipation and Chemical Reaction Effects
Autor: Yohannes Yirga, Tesfay, Daniel
The convective heat and mass transfer in nanofluid flow through a porous media due to a permeable stretching sheet with magnetic field, viscous dissipation, chemical reaction and Soret effects are numerically investigated. Two types of nanofluids, na
