Decolonising the postgraduate diploma in higher education curriculum at one university of technology in South Africa

The aim of this theoretical article is to explain efforts at decolonising the Postgraduate Diploma in Higher Education (PGDHE) curriculum at a university of technology (UoT) in South Africa. The main source of information was collected through relevant secondary data. The cost of continuing with Western knowledge organisation in the PGDHE programme destroys and undervalues African intellectualism, culture and literature, while imposing colonial language through prescribed texts. We argue that a clear understanding of decolonisation of the curriculum is necessary, to avoid the risk of implementing changes that will result in superficial alterations, rather than an inclusive curriculum that accentuates African intellectualism. The article recommends that a discourse around decolonisation should be sustained at all levels of the institution in re-thinking and re-evaluating the modules offered in the PGDHE programme to ensure they become more inclusive

Thermodynamic Analysis for Buoyancy-Induced Couple Stress Nanofluid Flow with Constant Heat Flux

This paper addresses entropy generation in the flow of an electrically-conducting couple stress nanofluid through a vertical porous channel subjected to constant heat flux. By using the Buongiorno model, equations for momentum, energy, and nanofluid concentration are modelled, solved using homotopy analysis and furthermore, solved numerically. The variations of significant fluid parameters with respect to fluid velocity, temperature, nanofluid concentration, entropy generation, and irreversibility ratio are investigated, presented graphically, and discussed based on physical laws
