Establishing a GC-MS/MS method to quantify redox markers in NDUFS4 knockout mice
(North-West University (South Africa), 2024)Through normal metabolic reactions, electron carriers such as nicotinamide adenine dinucleotide reduced and flavin adenine dinucleotide reduced (NADH and FADH2) are formed through various metabolic pathways which drive the ... -
The host status of selected soybean cultivars to Meloidogyne enterolobii under field and greenhouse conditions
(North-West University (South Africa), 2024)Soybean is a popular oilseed crop in South Africa with an increase in prodution and hectares that doubled in last 10 years. Crop production is predicted to increase with 41% by 2030. The crop is infected and damaged by a ... -
Evaluation of recruitment methodologies for Boscia albitrunca in the southern Kalahari, South Africa
(North-West University (South Africa), 2024)Boscia albitrunca is protected under the National Forest Act (Act No. 84 of 1998) as well as under the Northern Cape Nature Conservation Act (Act No. 9 of 2009). The survival of this species is threatened by farming practices ... -
Comparative analysis of mitochondrial DNA in haemogregarine (Apicomplexa: Adeleorina) blood parasites
(North-West University (South Africa), 2024)See attachment. -
Determining the regulatory awareness and knowledge of small business owners regarding waste management in the Nquthu Municipality, KwaZulu-Natal
(North-West University (South Africa), 2024)Waste management plays a crucial role in preserving the environment, promoting resource efficiency, reducing pollution, and safeguarding human and ecosystem health. It requires collaboration among individuals, businesses, ... -
An investigation into the distance dependence of storativity in dual porosity aquifers
(North-West University (South Africa), 2024)Parameterisation of hydraulic systems becomes increasingly difficult in fractured aquifers. Storativity is one of the main parameters used to quantify the available water in aquifers. This dimensionless value is known to ... -
The application of active and passive bioaccumulation methods to measure metallic and organic pollutants along the Namibian coastline
(North-West University (South Africa), 2024)Human activities and natural weathering processes are responsible for the input of elements and organic pollutants into marine environments. There is currently no ongoing marine pollution monitoring program in Namibia and ... -
Creation of near infrared spectroscopy calibration algorithms for soil water content prediction
(North-West University (South Africa), 2024)Water is arguably the most important human resource, and fresh water is becoming increasingly scarce. Irrigation in agriculture is one of the most water-demanding sectors, which urges the importance of effective management ... -
Novel data augmentation schemes for pose classification using a convolutional neural network
(North-West University (South Africa), 2024)Population aging is a global trend that can be attributed to declining fertility rates, longer life expectancies, and aging cohorts in many developed countries. The number of individuals over the age of 60 is expected to ... -
Evaluation of ROS production in OXPHOS knockout strains of C. elegans
(North-West University (South Africa), 2024)The oxidative phosphorylation (OXPHOS) system, comprising five complexes, regulates electron transport and adenosine triphosphate (ATP) synthesis in mitochondria. Dysfunctions in these complexes lead to diverse diseases. ... -
LC-ESI-MS/MS quantification of hair cortisol, cortisone and DHEA in combined oral contraceptive users
(North-West University (South Africa), 2024)Combined oral contraceptives (COCs) are used chronically by many women worldwide and in South Africa. Because many COC adverse effects coincide with symptoms of stress-related illnesses, including insulin resistance and ... -
Assessment of bacterial community and characterization of Pseudomonas aeruginosa in Diptera flies from livestock kraals and residential dumping sites in Potchefstroom
(North-West University (South Africa), 2024)The gut microbiota of Diptera flies is poorly understood, especially those that coexist with rural community farms and human waste sites. Pseudomonas aeruginosa pose challenges in both clinical and environmental contexts ... -
The influence of HIV-1 viral protein R sequence variation on immune activation, inflammation, and metabolism: implications for neurocognitive impairment
(North-West University (South Africa), 2024)Title: The influence of HIV-1 viral protein R sequence variation on immune activation, inflammation, and metabolism: implications for neurocognitive impairment Background Human immunodeficiency virus (HIV) affects ... -
Explainable machine learning model for predictive maintenance in smart agricultural facilities
(North-West University (South Africa), 2024)Machine Learning (ML) models in Smart Agricultural Facilities (SAF) often lack explainability, hindering farmers from taking full advantage of their capabilities. This study tackles this gap by introducing a model that ... -
Exploring plastic waste management practices surrounding the Agulhas National Park: The case of Struisbaai Harbour
(North-West University (South Africa), 2024)Marine pollution, particularly plastic waste, is an increasing global concern affecting coastal areas, ecosystems, and human well-being. While South Africa has seen some research on marine plastic pollution, there is a ... -
Dissertation accepted in fulfilment of the requirements for the degree Master of Science in Information Technology at the North-West University
(North-West University (South Africa), 2024)While digital platforms have become indispensable to daily life, the ethical dimensions of user privacy remain under-researched. This study's principal goal was to offer recommendations for safeguarding mobile device users ... -
Cloud computing adoption guidelines in a South African Higher Education Institution
(North-West University (South Africa), 2024-07)Global technology is advancing rapidly, particularly within higher education institutions, where remaining competitive in teaching and learning is paramount. Embracing cloud computing offers numerous benefits that higher ... -
Simultaneous quantification of urinary oxidative stress markers in women using combined oral contraceptives
(North-West University (South Africa), 2023)In physiological samples, it is difficult to measure the presence of free radicals. Therefore, secondary oxidative products excreted in urine after detoxification are quantified instead, as they are proportional to the ... -
Ambient and household exposure to particulate matter in a low income settlement
(North-West University (South Africa), 2023-12)Ambient and indoor exposure to particulate matter (PM) is a worldwide health problem, which is most prevalent in developing nations, and typically affects vulnerable groups (elderly, children, and sick people). In South ... -
New characterisation-based tests for symmetry
(North-West University (South Africa), 2021-08)We propose new tests for symmetry of a distribution around an unspecified centre. The first set of tests is based on a lesser-known characterisation involving symmetric integration of the distribution function around the ...
