The role of Tarebia granifera as an invasive in freshwater ecosystems of Southern Africa
(North-West University (South Africa), 2022)
Over the past few decades, the increase in import and trade frequency of exotic aquatic species for aquarium hobby sales have led to the introduction and establishment of several invasive snail species on a global scale. ...
Evaluating radiological impacts due to uranium mining in the Erongo Region, Namibia
(North-West University (South Africa), 2022)
The unambiguous and continuously increasing exposures of human beings to terrestrial radiations is highly attributed to naturally occurring radioactive materials in the environments. Background radiation had been increasing ...
Efficient energy-aware controller placement in software-defined wireless sensor networks
(North-West University (South Africa), 2022)
A centralized controller in the Software-defined Wireless Sensor Networks (SDWSN)
environment poses a single point of failure and is inapt for a large-scale network. As leverage,
multiple controllers have been introduced ...
Indoor radon measurements in dwellings and public buildings within the KOSH gold mining region, North West Province
(North-West University (South Africa), 2022)
A wide distribution of indoor radon levels was observed for measurements conducted in schools and homes in different areas. Schools’ results showed a minimum of 18.06 Bq.m-3 and a maximum of 154.96±20.48 Bq.m-3 with the ...
Effect of rutin on TNF-α-induced insulin resistance in 3T3-L1 cells
(North-West University (South Africa), 2022)
Obesity has become a growing epidemic globally and a burden to the health care system due to its association or contribution to the development of other chronic diseases. The excessive accumulation of fat in adipocytes or ...
Agro-morphological and genetic characterization of advanced potato (Solanum tuberosum L.) breeding lines in Mahikeng, South Africa
(North-West University (South Africa), 2022)
One of the most important strategies for increasing crop productivity and improvement in potato yield output is the development and introduction of new cultivars. Phenotypic characteristics are the first aspects to consider ...
Determination of tritium (3H) and radiocarbon (14C) levels in groundwater using alpha/beta spectrometry
(North-West University (South Africa), 2022)
With the current state of water scarcity in Mahikeng due to the low water levels, increasing population and increased demand for fresh water supply, it is therefore crucial to ensure the sustainability and availability of ...
Age structured population dynamics with applications in epidemiology
(North-West University (South Africa), 2022)
Models describing the dynamics of biological phenomena that evolve in stages have been
studied extensively using time-delay mathematical models. Recently, these models have
evolved into age structured models with age ...
Development of a two-level full factorial model to analyse antenatal HIV data
(North-West University, 2018)
The present study is based on antenatal HIV data collected annually by South Africa’s National Department of Health (NDoH) from 2001 to 2010. The data was obtained by sampling pregnant women attending the clinic for antenatal ...
Molecular modelling of species pertaining to the solvent extraction of tantalum penta-fluorides
(North-West University, 2018)
Solvent extraction (SX) is used for the separation and purification of various metals, including tantalum (Ta) and niobium (Nb). Industrial processes for the separation of Ta and Nb traditionally use high concentrations ...
