Comparative analytical work-up for reproducible metabolite derivatisation for gas chromatography-mass spectrometry
(North-West University (South Africa), 2023)Gas chromatography-mass spectrometry (GC-MS) is one of the most popular analytical instruments used for metabolomics analyses. However, chemical derivatisation of the sample is generally required to increase the volatility ... -
The suitability of NAD(P)/NAD(P)H as redox agents for gold nanostar shape alteration in colourimetric clinical enzymology
(North-West University (South Africa), 2024)Biosensors have proven to be a strong instrument for detecting varied targets such as proteins, DNA, small molecules (disease biomarkers), toxins and metabolites with great sensitivity and specificity. The fundamental goal ... -
Effects of climate variability, land-use change and transformation on grassland plant diversity in South Africa
(North-West University (South Africa), 2024)Grasslands as open ecosystems are not successional stages or degraded forests but are ancient old-growth systems supporting a high diversity of fauna and flora. It is now known that forests and grasslands are two distinct ... -
Developing a conceptual model of resilience of communities to climate change in the Cuvelai Etosha Basin
(North-West University (South Africa), 2024)Research on vulnerability and adaptation to climate change have increased because of the growing realisation that the response determines resilience. Societal capacity to adapt is linked to both severity of impacts and ... -
Landscape functionality and restoration of degraded sites in the Mokala and Karoo National Parks of South Africa
(North-West University (South Africa), 2024)The reduction in plant cover and density, as well as other ecological processes, all contribute to the deterioration of the land in ecosystems. In hyper-arid, arid, and semiarid regions, frequent and ongoing land degradation ... -
Numerical simulations of the evolution of astrospheres in different interstellar conditions
(North-West University (South Africa), 2024)Astrospheres are large-scale structures arising from the interaction between the stellar wind and the interstellar medium (ISM). This study investigates the effect of various parameters, such as the simulation time, mass ... -
Integrating informal waste reclaiming practices into the formal waste management sector: Madibeng Local Municipality
(North-West University (South Africa), 2024)Waste pickers, crucial for waste management, often face poor conditions and legal hurdles. Integrating them requires clear policies, infrastructure, and overcoming challenges like safety risks and resistance to change. ... -
Determining the sensitivity of flood risk assessment to different multiple criteria analysis approaches
(North-West University (South Africa), 2024)Floods, as a prevalent and destructive natural hazard, have globally inflicted substantial human, economic, and environmental losses. With floods affecting approximately 1.6 billion people and accounting for 44% of all ... -
Perceptions on integrating informal waste tyre dealers into the formal waste sector: Emalahleni Local Municipality
(North-West University (South Africa), 2023)In South Africa, the prohibition of waste tyre disposal in landfills has positively impacted landfill usage but led to an increase in illegal dumping of tyres. Although the informal waste sector plays an important role ... -
A Monte Carlo simulation study of the excitation of molecules in high-mass star forming regions
(North-West University (South Africa), 2024)Astronomical maser emission occurs in various astrophysical environments and can be used to infer the physical properties of the regions where they are excited. A key component of interpreting the presence of maser emission ... -
The use of beneficial bacterial endophytes for improving biomass yield and nutritive value of vegetables

Evaluating E-waste management practices in buildings of the National Department of Public Works, South Africa
(North-West University (South Africa), 2024)E-waste is a universal problem, and in 2014, approximately 41.8 million tonnes of e-waste was generated worldwide. In 2017, the Global E-waste Monitor also indicated that there was a 5% year on year increase in E-waste ... -
Industry perceptions of South African Extended Producer Responsibility (EPR) Regulations: Challenges and opportunities for the paper and packaging industry
(North-West University (South Africa), 2024)The waste management environment in South Africa is undoubtedly characterised by collection and landfilling with a limited amount of recycling. Landfills have several detrimental environmental effects, including air pollution ... -
Isothermal amplification assays for point of-care diagnostics of bovine brucellosis and tuberculosis in South Africa
(North-West University (South Africa), 2024)Bovine brucellosis, caused by Brucella abortus, is a disease of global socio-economic importance. Bovine tuberculosis (bovine TB) is a chronic wasting disease of cattle caused primarily by Mycobacterium bovis. Complete ... -
Stakeholder perspectives of the key challenges and opportunities in implementing organic waste diversion in the Western Cape
(North-West University (South Africa), 2024)Organic waste diversion from landfill presents challenges in both developed and developing countries, where it accounts for 32% and 50% of the total waste stream respectively. From international research these challenges ... -
