Influence of rotation on transversely isotropic piezoelectric rod coated with a thin film
(Polish Academy of Sciences, 2018)In this paper, the influence of rotation on axisymmetric waves of a piezoelectric rod coated with a thin film is studied using constitutive form linear theory elasticity and piezo-electric equations. Potential functions ... -
The mapping and investigation of radionuclide pollution in the processing plant of a spent phosphate mine by using GIS techniques
(CONSAS, 2018)The mining and refinement of phosphate is characterised by high levels of uranium. An in situ gamma ray survey was done at the processing plant of a spent phosphate mine near Vredenburg on the west coast of South Africa ... -
A mathematical model for coinfection of listeriosis and anthrax diseases
(Hindawi, 2018)Listeriosis and Anthrax are fatal zoonotic diseases caused by Listeria monocytogene and Bacillus Anthracis, respectively. In this paper, we proposed and analysed a compartmental Listeriosis-Anthrax coinfection model ... -
Irreversibility analysis of hydromagnetic flow of couple stress fluid with radiative heat in a channel filled with a porous medium
(Elsevier, 2017)Numerical analysis of the intrinsic irreversibility of a mixed convection hydromagnetic flow of an electrically conducting couple stress fluid through upright channel filled with a saturated porous medium and radiative ... -
Optimal control and cost effectiveness analysis for Newcastle disease eco-epidemiological model in Tanzania
(Informa UK Limited, trading as Taylor & Francis Group, 2017)In this paper, a deterministic compartmental eco- epidemiological model with optimal control of Newcastle disease (ND) in Tanzania is proposed and analysed. Necessary conditions of optimal control problem were rigorously ... -
Modelling and optimal control of pneumonia disease with cost-effective strategies
(Informa UK Limited, trading as Taylor & Francis Group, 2017)We propose and analyse a nonlinear mathematical model for the transmission dynamics of pneumonia disease in a population of varying size. The deterministic compartmental model is studied using stability theory of differential ... -
Effects of thermal radiation on MHD peristaltic motion of walters-B fluid with heat source and slip conditions
(Regional Information Center for Science and Technology, 2017)In this paper, we examine the combined effects of magnetic field, thermal radiation, heat source, velocity slip and thermal jump on peristaltic transport of an electrically conducting Walters-B fluid through a compliant walled ... -
New interventions and sustainable solutions : reappraising illegal artisanal mining in South Africa
(University of Cape Town, Centre of Criminology, 2018)Despite being recognised as a significant contributor in the South African economy, the mining industry is riddled with illegal mining activities. Though it remains difficult to precisely measure the extent of the activities ... -
Thermal decomposition analysis in a sphere of combustible materials
(Sage, 2017)In this article, we look at spontaneous combustion due to exothermic chemical reaction taking place within a stockpile of combustible material. The model includes mass and energy balance equations in a spherical domain. ... -
Soret and Dufour effects on MHD flow with heat and mass transfer past a permeable stretching sheet in presence of thermal radiation
(NISCAIR-CSIR, 2017)An analysis has been carried out to study the combined effects of the magnetic field, Joule heating, thermal radiation absorption, viscous dissipation, Buoyancy forces, thermal-diffusion and diffusion-thermion the convective ... -
The impact of saccharomyces cerevisiae on a wine yeast consortium in natural and inoculated fermentations
(Frontiers Media, 2017)Natural, also referred to as spontaneous wine fermentations, are carried out by the native microbiota of the grape juice, without inoculation of selected, industrially produced yeast or bacterial strains. Such fermentations ... -
MHD slip flow and heat transfer over an exponentially stretching permeable sheet embedded in a porous medium with heat source
(Global Digital Central, 2017)Steady two dimensional laminar magnetohydrodynamic (MHD) slip flow and heat transfer of a viscous incompressible and electrically conducting fluid past over a flat exponentially non-conducting stretching porous sheet ... -
Modelling and optimal control of typhoid fever disease with cost-effective strategies
(Hindawi Publishing Corporation, 2017-09)We propose and analyze a compartmental nonlinear deterministic mathematical model for the typhoid fever outbreak and optimal control strategies in a community with varying population.The model is studied qualitatively ... -
The investigation of radionuclides distributions in beach sand by means of GIS techniques
(CONSAS Conference, 2015-11)A transportable and robust gamma ray detection system (GISPI) was employed to determine the concentrations of naturally occurring radionuclides on various beaches in and around Saldanha Bay, located on the West Coast ... -
Optimal control of HIV/AIDS in the workplace in the presence of careless individuals
(Hindawi Publishing Corporation, 2014-06-26)A nonlinear dynamical system is proposed and qualitatively analyzed to study the dynamics of HIV/AIDS in the workplace. The disease-free equilibrium point of the model is shown to be locally asymptotically stable if the ... -

Computational dynamics of arterial blood flow in the presence of magnetic field and thermal radiation therapy
(Hindawi Publishing Corporation, 2014-04-22)We conduct a numerical study to determine the influence of magnetic field and thermal radiation on both velocity and temperature distributions in a single blood vessel. The model here assumes that blood is a Newtonian ... -
Application of successive linearisation method to squeezing flow with bifurcation
(Hindawi Publishing Corporation, 2014-01-02)This paper employs the computational approach known as successive linearization method (SLM) to tackle a fourth order nonlinear differential equation modelling the transient flow of an incompressible viscous fluid between ... -
Unsteady hydromagnetic flow of radiating fluid past a convectively heated vertical plate with the Navier slip
