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 ...
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). ...
In this thesis, we analyze a mathematical model for the spread of malaria that consists of
ten components. The human host population is divided into two main categories: semiimmune,
which included all individuals who ...
The understanding of the nuclear breakup dynamics at sub-barrier incident energies,
remains a hot subject in Nuclear Physics. In this dissertation, the breakup of the weaklybound
neutron-halo 11Be nucleus impinging on a ...
The structure, morphology, optical, and electrical characteristics of rare earth (RE) metal ions, few-walled carbon nanotubes (FWCNT) and zinc oxide (ZnO) nanocomposite for possible applications such as electron acceptor ...
Transition metal hydrides, including CrH and others, have a significant impact on
chemical synthesis, serving as intermediates and in solid matrix samples for infrared
spectroscopy. Moreover, the CuLi molecule provides ...
