Poor mathematics performance is a global issue, including in South Africa, with a reported decline in skills worldwide Berisha et al. (2024). Learners struggle with understanding algebraic fractions, which are essential ...
The present work examined the occurrence of efavirenz, ibuprofen, naproxen, sulfamethoxazole, and trimethoprim in wastewater, sewage sludge, river water, estuaries, seawater, garden soil, and vegetables. This was achieved ...
Let L be a completely regular frame and RL be the ring of real-valued continuous functions
on L. In this dissertation, we will study the maximal ideals and prime ideals of the ring RL
which were described by Dube in [20] ...
The National Curriculum Statement (NCS), implemented in 2003, marked the formal introduction of mathematical modelling into the South African curriculum. This represented a significant shift, as mathematical modelling had ...
In this work, we study synchronisation in power grids using a classical phase oscillator
model that can be thought of as a variant of the famous Kuramoto model for coupled
phase oscillators. In the recent literature, the ...
The global shift toward sustainable energy technologies has increased the demand for advanced energy storage systems that deliver both high energy and power densities. Conventional supercapacitors provide excellent power ...
Water is an essential resource for human survival, agriculture, and livestock. However, over the past thirty years, the World Health Organization has reported growing concerns about the impact of environmental pollution ...
Mental synthesis is the human ability to purposefully form novel mental imagery by
combining memories of different modalities. The neuronal mechanisms that facilitate
this process remain poorly understood. Mental synthesis ...
This study investigates the transmission dynamics of COVID-19 and Lassa
fever, with particular attention to the risks and implications of co-infection. By
dividing the human population into epidemiological compartments, ...
Various nations within sub-Saharan Africa are currently facing different
stages of loadshedding, with South Africa being of no exception to this trend.
Loadshedding has been implemented as a strategy to manage ...
The 2D crystal lattice graphene has attracted tremendous research interest due to its exceptional properties that provide interesting opportunities for many applications, including energy storage technologies. Graphene has ...
This thesis studies the applications of Lie group analysis and conserved vectors to
multi-dimensional nonlinear partial differential equations. Exact solutions and conservation
laws are obtained for such equations. The ...
We report on first-principles density functional theory (DFT) calculations of interactions between extrinsic defects and intrinsic structural defects in silicene. Specifically, we investigate the stability, structural, ...
Over the past few years, heavy metal ion (HMI) pollution has become a crucial matter due to their threat to human health and ecological systems.,. Furthermore, HMIs have been reported to be hazardous, persistent, and in ...
Industrial waste materials have garnered increased attention as viable adsorbents that could be used for the extraction of heavy metals and organic pollutants from wastewater. This is primarily due to their abundant ...
Emerging pollutants (EPs) provide a new global water quality concern, potentially posing a major damage to human health and the surrounding. Pharmaceuticals, extensively used in both human and veterinary medicine, have ...
The neonicotinoid pesticides (NEOs) have been used over the years for plant protection. The use of these NEOs on crops and oil seed plants has led to vegetable oil and crop produce contamination. The four selected NEOs for ...
Contamination of pet food with heavy metals is a crucial problem worldwide and it results in adverse health effects on pets, massive recall of the product, damaging of the brand name and financial loss. Therefore, researchers ...
Microextraction sample preparation methods are miniaturized formats which contributes to green approaches in Analytical Chemistry. They are mainly characterized by the minimum use of organic solvents.
The aim of this ...
The nanocomposite membranes were fabricated by incorporating palladium
nanoparticles into Nafion® matrix to develop suitable membrane to be used as polymer
electrolyte membrane (PEM) in Direct Methanol Fuel Cell (DMFC). ...
