Estimation of radon potential through measurement of uranium concentrations in granite geology

Bezuidenhout, Jacques (Academy of Science of South Africa, 2019)

The geology of an area can be used as a predictor for radon potential. Granite rock typically contains a high concentration of uranium and subsequent elevated emanation of radon gas. The geology of the western part of the ...

Assessing public participation strategies in people’s housing process in Wallacedene

Sandile, Unathi (Stellenbosch : Stellenbosch University, 2020-12)

ENGLISH ABSTRACT: Public participation is important in housing development. Since the start of democratic government in South Africa, local governments have been encouraged to promote and use public participation to empower ...

Theoretical study of variable viscosity nanofluids flow in microchannels

Monaledi, Ramotjaki (Stellenbosch : Stellenbosch University, 2020-12)

ENGLISH ABSTRACT: The study of fluid flow and heat transfer through a microchannel is an important research area due to its wide applications in engineering and industrial processes. Some practical applications include ...

Influence of rotation on transversely isotropic piezoelectric rod coated with a thin film

Selvamani, Rajendran; Makinde, Oluwole Daniel (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 ...

Chemically reacting on MHD boundary-layer flow of nanofluids over a non-linear stretching sheet with heat source/sink and thermal radiation

Makinde, Oluwole Daniel; Mabood, Fazle; Ibrahim, Mohammed S. (Thermal Science, 2018)

In this paper, steady 2-D MHD free convective boundary-layer flows of an electrically conducting nanofluid over a non-linear stretching sheet taking into account the chemical reaction and heat source/sink are investigated. ...

The mapping and investigation of radionuclide pollution in the processing plant of a spent phosphate mine by using GIS techniques

Bezuidenhout, Jacques (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

Osman, Shaibu; Makinde, Oluwole Daniel (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

Eegunjobi, A. S.; Makinde, O. D. (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

Hugo, Alfred; Makinde, Oluwole Daniel; Kumar, Santosh; Chibwana, Fred F. (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

Tilahun, Getachew Teshome; Makinde, Oluwole Daniel; Malonza, David (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
