Structural features of air-processible methyl ammonium lead triiodide (MAPbI3) perovskite thin films grown on Al-doped ZnO Nanowire Arrays
(University of the Western Cape, 2023)The performance of air stable, mixed halide (MAPbI3-xClx) perovskite based solar cells is highly dependent on the quality and stability of the perovskite thin film, which in turn, is dependent on the substrate on which it ... -
An assessment of river and wetland morphology dynamics using geospatial techniques
(University of the Western Cape, 2023)Land surface modification has intensified in recent years, and it continues to be an ongoing process. This raises serious concerns about changes in land use and land cover (LULC) since some of these changes have led to ... -
A framework for the analysis of discrete irregular patterned sequential datasets
(University of the Western Cape, 2023)Trial-and-error is often used for developing new deep learning models. There is no systematic procedure for improving existing models for predicting irregular sequential time-series. This research developed a systematic ... -
Investigating genetic diversity and microRNA of Hermetia illucens (the black soldier fly) to breed for mass production of a novel sustainable protein
(University of the Western Cape, 2023)Introduction: A new sustainable source of protein is needed to meet the demands of the growing global population. Insect meal is a suitable replacement, and the black soldier fly (BSF) is the most used insect in industrial ... -
Genomic epidemiology of Rift Valley fever in East Africa
(University of the Western Cape, 2023)Rift Valley fever (RVF) is a climate-driven zoonotic disease of significant importance to public and livestock health given its epidemic potential. The disease was first identified in 1930 in the great rift valley region ... -
An assessment of factors influencing the spatial variability of iron concentrations in groundwater in selected areas of the Western Cape Province.
(University of the Western Cape, 2023)Groundwater in South Africa, and more specifically the Western Cape Province (WCP), has become of major interest in recent years due to the unpredictable climatic conditions and the uncertainty of surface water to continuously ... -
On the efficacy of enhanced feature selection methods for supervised crime prediction
(University of the Western Cape, 2023)The challenge of crime across the globe has necessitated several considerations for crime preventive measures. There exist a variety of crime prevention strategies, such as the use of necessary weapons or tools to respond ... -
Influence of data accuracy and non-use of quality information on reproductive health: a comparative study of Nigeria and South Africa
(University of the Western Cape, 2023)In healthcare settings, information systems play a critical role in providing safe, timely, and effective healthcare services. Decision-making on medical supplies, healthcare providers, service delivery, finance, and ... -
Exploring a participatory multi-stakeholder engagement approach to address chronic medicine use
(University of the Western Cape, 2023)Background: In South Africa, chronic diseases (CD) fall into the quadruple burdens of diseases. In 2018 the World Health Organization (WHO) reported that chronic diseases were responsible for more than fifty percent of ... -
Rainfall induced transient pressure wave mechanisms and pore water pressure dynamics in tailings
(University of the Western Cape, 2023)Tailings Storage Facilities are some of the largest engineered structures responsible for the containment of mining waste, yet some physical/hydrological processes causing slope instability are still poorly understood. ... -
Chemical pressure-induced transition of the magnetic ground state from ferromagnetic to antiferromagnetic order in CeCuGe and DyCuIn alloys
(University of the Western Cape, 2023)Rare-earth intermetallic compounds continue to attract considerable attention, due to their fundamental importance in understanding physical properties and potential applications based on a variety of phenomena. The ternary ... -
Applying a lagrangian trajectory model to investigate and describe the distribution of drifting ecklonia maxima within the benguela upwelling system
(University of the Western Cape, 2023)Macroalgal morphological variation is determined to a large extent by a combination of environmental factors, with wave exposure and temperature perhaps the main influences, as they are key environmental properties to which ... -
Accelerating reionization simulations using machine learning
(University of the Western Cape, 2023)Epoch of Reionization (EoR) refers to the time in the history of the universe when the appearance of the first luminous sources reionized the intergalactic medium (IGM). The EoR carries a wealth of information regarding ... -
Dexamethasone's impact on LPS-induced inflammation of blood-brain barrier endothelial cells
(University of the Western Cape, 2023)The blood-brain barrier (BBB) serves as a protective and regulatory barrier between the blood and the brain. Microvascular endothelial cells provide homeostatic regulation of the central nervous system (CNS). BBB integrity ... -
In vitro neuroprotective potential of phyllanthin in MPP+- induced toxicity in SH-SY5Y neuroblastoma cells
(University of the Western Cape, 2023)Parkinson’s disease (PD) is the second most common age-related neurodegenerative disease after Alzheimer’s disease, with an estimated 9 million people projected to be affected worldwide by the year 2030. PD is associated ... -
Female unemployment in South Africa: insight from the 2021 labour force survey.
(University of the Western Cape, 2023)The study focused on female unemployment and aimed to establish whether or not there is a relationship between female unemployment and demographic characteristics, whether the currently unemployed have ever worked or not, ... -
An evaluation of the biopesticidal characteristics of Helichrysum marifolium and Helichrysum patulum and their effects on animal metabolism
(University of the Western Cape, 2002)There are a number of pesticides that are suspected to be endocrine disrupters Many of these pesticides are man-made. Endocrine disrupters are chemicals that can lead to an increase in birth defects, sexual abnormalities, ... -
Conjugacy classes of some projective linear groups
(University of the Western Cape, 1992)Given a finite set X of distinct symbols the symmetric group S* and the alternating group A* are obtained without further constructions. More interesting groups are contrived, however, by imposing a certain structure on ... -
Investigation of ternary catalysts as anode catalysts for direct methanol fuel cell
(University of the Western Cape, 2023)This chapter reports on various catalyst synthesis methods (impregnation, polyol, modified polyol and microwave-assisted modified polyol methods) to determine which method would result in the most electrochemically active ... -
