A Mathematical Model for Mycolactone Toxin Reaction and Diffusion in Cell Cytoplasm

Peter Romeo Nyarko, Isaac Kwame Dontwi & Nana Kena Frempong · Journal of Advances in Mathematics and Computer Science · 2018

The study of mechanisms and transport of proteins inside cells provide understanding of the dynamics of biological systems and give clues to biological effect of drugs on our system. Reaction-diffusion mechanisms inside cells control various cell functions from adhesion, haptotax...

A Formal Homogenization Approach to Piping Flow Erosion with Deposition in a Spatially Heterogeneous Soil

Adu Sakyi, Peter Amoako-Yirenkyi & Isaac Kwame Dontwi · Journal of Advances in Mathematics and Computer Science · 2020

We model and simulate piping erosion phenomena with deposition in a spatially heterogeneous soil mass motivated by seepage flow. The soil is considered to be a porous media with periodic positioning of pores spread around cylindrical structures or microstructures making the heter...

A Rigorous Homogenization for a Two-Scale Convergence Approach to Piping Flow Erosion with Deposition in a Spatially Heterogeneous Soil

Adu Sakyi, Peter Amoako-Yirenkyi & Isaac Kwame Dontwi · Journal of Advances in Mathematics and Computer Science · 2020

We present a rigorous homogenization approach to modelling piping flow erosion in a spatially heterogeneous soil. The aim is to provide a justication to a formal homogenization approach to piping flow erosion with deposition in a spatially heterogeneous soil. Under the assumption...

Fractional Order SIR Model with Constant Population

Eric Okyere, Francis Tabi Oduro, Samuel Kwame Amponsah, Isaac Kwame Dontwi & Nana Kena Frempong · Journal of Advances in Mathematics and Computer Science · 2016

The main objective of this paper is to formulate an epidemiological model using fractional order derivatives which has an advantage over the classical integer order models due to its memory effect property. Our mathematical formulation of the non-integer order initial value probl...
