The recombinant expression and enzymatic charaterisation of human ACSM2 ligase.
(North-West University (South Africa), 2023-10)Glycine conjugation is a highly conserved Phase 2 biotransformation reaction for xenobiotic carboxylic acids such as benzoate, salicylate, and medium-chain fatty acids. The glycine conjugation pathway can be saturated by ... -
Pricing European options using artificial neural networks
(North-West University (South Africa), 2023-10)The study’s focus is to examine the pricing of European options using artificial neural networks. It aims to use the predictive powers of artificial neural networks to forecast option prices for European puts and calls ... -
Computational study of Raney nickel type catalysts for the alkaline oxygen evolution reaction
(North-West University (South Africa), 2023-10)The growth of the global population, together with an increase in pollution caused by the use of fossil fuels for energy production, has led to an environmental and energy crisis. This crisis necessitates the search for ... -
An environmental assessment of hydroponic farming in the Johannesburg Metropolitan area and potential for the Vaalharts region
(North-West University (South Africa), 2023-10)The Johannesburg inner city, through various intervention strategies to improve local food security and create a reliable model for small-scale vegetable production, has introduced innovative agricultural initiatives on ... -
The dynamics of fluvial transportation of uranium in the Rietspruit river system in South Africa
(North-West University (South Africa), 2023-10)Mining of precious metals started many years ago, for instance, gold (Au) and the offshoot uranium (U) mining in South Africa's Witwatersrand Basin. Consequently, mining activities contaminate the environment with ... -
Evaluating the effectiveness of air quality management plans as a governance instrument in South Africa
(North-West University (South Africa), 2023-10)Since the 19th century, industrialised societies introduced technologies to enhance economic production and productivity, most notably related to energy generation. These caused ever-increasing levels of air pollution. The ... -
The historical and seasonal distribution of schistosomiasis transmitting vectors in the Mpumalanga province, South Africa
(North-West University (South Africa), 2023-10)Schistosomiasis is a parasitic disease transmitted by freshwater host snails and is prevalent in tropical and subtropical regions. The spatial-temporal focal distribution and transmission of schistosomiasis are determined ... -
Anisotropy and polarization effects in blazar emission
(North-West University (South Africa), 2023-10)Blazars are radio-loud (RL) active galactic nuclei (AGNs) whose relativistic jets are directed at us. These sources are observed to have spectral energy distributions (SEDs) with two broad-humped components, significant ... -
Investigating waste source separation models in Gauteng: Private sector versus co-operatives
(North-West University (South Africa), 2023-10)Globally, the rapid rate of urbanisation, growth in populations and changing consumption patterns have significantly contributed towards increased municipal solid waste (MSW) generation. The rising costs of managing existing ... -
Application of data mining and machine learning techniques for geohydrological datasets in South Africa
(North-West University (South Africa), 2023-10)A desktop study was conducted to research data-driven modelling techniques to classify relationships between borehole parameters and the relevant geological setting. Borehole surveying and drilling is a costly endeavour ... -
Multi-wavelength Study of Radio Galaxies in MeerKAT fields
(North-West University (South Africa), 2023-10)Active galaxies are distinct sub-types of galaxies; their centres, known as Active Galactic Nuclei (AGN), are the brightest and most persistently luminous objects in the cosmos and the AGN core is where the vast majority ... -
Biodiversity and systematics of parasitic Crustacea infesting southern African freshwater fishes
(North-West University (South Africa), 2023-10)Crustaceans (Arthropoda: Crustacea) are regarded as the most morphologically diverse group in the phylum Arthropoda, and they have the greatest diversity of parasitic forms. Parasitic crustaceans have adapted several ... -
Screening of Pt/Ni bimetallic electrocatalysts using DFT calculations
(North-West University (South Africa), 2021-06)Clean, renewable energy could be produced from the electrocatalytic splitting and recombination of water in electrolysers and fuel cells, called electrochemical devices. However, the development of these electrochemical ... -
