(University of Pretoria, 2019)Background The South African Government is spending huge amounts of money (about R64 billion for the fiscal years 2015/16 to 2018/19 as per the revised strategic plan – vote 36) and more than R30 billion was targeted ...
-
(University of Pretoria, 1972)The effective mean temperature difference (M.T.D.) in a heat exchanger depends on the terminal temperatures of the two streams, the distributions of flows over the transfer area with the associated local mixing effects ...
-
(University of Pretoria, 2021)Amoss is an equation-orientated stochastic simulation platform, developed on open-source software. It is designed to facilitate the development and simulation of Sasol value chain models using the Moss methodology. The ...
-
(University of Pretoria, 2020)Sustainable, environmentally friendly, and renewable energy sources are urgently needed as concerns about carbon emissions and the depletion of fossil fuels are becoming worrying. It is vital to explore cost-effective ...
-
(University of Pretoria, 2019)Energy systems and products have always focused heavily on the fuel rather than the oxidant. That oxygen is the definitive factor in the exothermicity of combustion reactions rather than the fuel is demonstrated ...
-
(University of Pretoria, 2020)Fugitive coal dust emissions are a cause of concern from a government and public perspective, particularly so in communities living in proximity of the coal mines. Atmospheric dust contains various constituents and coal ...
-
(University of Pretoria, 2020)Selenium (Se) in the aquatic environment is predominantly found as the soluble selenium oxyanions; selenate (SeO42-), and selenite (SeO32-). These oxyanions are toxic, and they readily bio-accumulate in the food chain. ...
-
(University of Pretoria, 2020-08-28)Biofilms of the bovine rumen bacterium Actinobacillus succinogenes have demonstrated their exceptional capabilities as biocatalysts for high productivity, titre and yield production of succinic acid (SA). Succinic acid is ...
-
(University of Pretoria, 2020)Engineered nanoparticles (ENPs) (e.g. zinc oxide (nZnO) and iron oxide (nFeOx) and organic pollutants (e.g. triclosan (TCS)) are among emerging contaminants (ECs) of environmental concern. However, to date there is limited ...
-
(University of Pretoria, 2020-08-27)The challenge of economical separation of tiny microalgal cells from dilute solution restricts their industry commercialization as promising biosorbents. In the fundamental work of this thesis, self-flocculating microalga ...
-
(University of Pretoria, 2020)Induktiefgekoppelde-plasmareaktore (IGP’s) het toepassings in verskeie industrieë, insluitend die voorbereiding van metaalpoeiers vir laagvervaardiging. Die skermgas (ook skutgas gnoem) speel ’n belangrike rol in die ...
-
(University of Pretoria, 2020)With increasing number of nanoproducts being commercialized globally; and consequent release of engineered nanoparticles (ENPs) into different environmental compartments with unknown impacts has raised concerns. Several ...
-
(University of Pretoria, 2019-10)The measurement of ambient particulate concentration (PM10 and PM2.5) using active monitors requires expensive or labour-intensive apparatus or both. Although PM is a priority pollutant, this has precluded widespread or ...
-
(University of Pretoria, 2019)Dynamic simulation programs were created in the Python programming language, to describe a laboratory scale, sub-zero distillation column, that is used to separate mixtures of tetrafluoroethylene (TFE), hexafluoropropylene ...
-
(University of Pretoria, 2020-02-14)Extraction of Li2CO3 from Zimbabwean petalite, from the Bikita deposit, was studied using ammonium bifluoride (ABF) digestion at temperatures ranging from room temperature to 600 oC, and gram quantities of ore. ABF digestion ...
-
(University of Pretoria, 2020)Water contamination is one of the leading challenges faced by the global community. This is due to the escalating population growth and anthropogenic activities which have led to water supply being inversely proportional ...
-
(University of Pretoria, 2019)Background The four-carbon dicarboxylic acids of the tricarboxylic acid cycle (malate, fumarate and succinate) remain promising bio-based alternatives to various precursor chemicals derived from fossil-based feed stocks. ...
-
(University of Pretoria, 2019)Zirconium (Zr) and hafnium (Hf) metals have drawn considerable attention due to their various applications, especially in the nuclear industry where zirconium is used as a cladding material for nuclear reactors due its low ...
-
(University of Pretoria, 2019)Malaria is a principal cause of illness and death in countries where the disease is endemic. The indoor residual sprays of insecticides and indoor use of long-lasting insecticide-treated nets (LLINs) are practical methods ...
