Developing a model of school climate unique to secondary schools in South Africa: A multilevel analysis approach
(University of the Western Cape, 2018)
The educational landscape in South Africa is unique and has also seen many changes since the dawn of democracy more than 20 years ago. The apartheid education system was marred by severe inequalities between schools and, ...
The synthesis and characterization of mixed-organic-cations tin halide perovskites for enhanced photovoltaic cell application
(University of the Western Cape, 2018)
In this research, novel hybrid perovskite materials were synthesized, characterized and applied in photovoltaic cells (PVCs) to enhance the performance of PVCs. Mixed-organic-cations tin halide perovskites (MOCTPs) were ...
Seasonal differences in semen characteristics and sperm functionality in Tankwa goats
(University of the Western Cape, 2018)
Tankwa goats have been free-ranging in the Tankwa Karoo National Park in the Northern Cape for more than 80 years. A genetic study concluded that these feral goats are a unique genetic resource compared to other goat breeds ...
Factors influencing infant and child mortality in Zimbabwe
(University of the Western Cape, 2018)
According to a 2010 report by the United Nations, mortality rates among children under the age of five remain extremely high in most countries in sub-Saharan Africa in which Zimbabwe is one of them. Child mortality in ...
Identification and ranking of pervasive secondary structures in positive sense single-stranded ribonucleic acid viral genomes
(University of the Western Cape, 2018)
The plasticity of single-stranded viral genomes permits the formation of secondary structures
through complementary base-pairing of their component nucleotides. Such structures have
been shown to regulate a number of ...
Radon exhalation of building materials
(University of the Western Cape, 2018)
Public concern about all radiation and radon exhalation from building
materials has been highlighted recently. The purpose of this study is
to address this public concern and to investigate the contribution of
building ...
Formulation and evaluation of polymeric micelles for improved oral delivery of tenofovir disoproxil fumarate and zidovudine using poly-lactic-co-glycolic acid nanoparticles
(University of the Western Cape, 2018)
Background: Tenofovir disoproxil fumarate (TDF) and Zidovudine (AZT) are both nucleotide and nucleoside analogue reverse transcriptase inhibitors (NtRTIs and NRTIs), respectively. They are used for the management and ...
Design and evaluation of fast dispersible tablets of lamivudine using selected natural superdisintegrants
(University of the Western Cape, 2018)
Fast dispersible tablets (FDTs) are solid single-unit dosage forms that are placed in the mouth and allowed to disperse or dissolve in the saliva without the need of water. The basic approach to formulating FDTs consists ...
Evaluation of cytotoxic activity of gold nanoparticles naturally synthesised from South African indigenous medicinal plant extracts
(University of the Western Cape, 2018)
Nanotechnology has emerged as a promising field in the quest to address health conditions. Green nanotechnology is a fairly new branch of nanotechnology, which aims to produce and utilize nanomaterials in a way that is ...
Involvement of abscisic acid and H2O2 in antioxidant enzyme activities mediated by nitric oxide synthase-like activity in maize
(University of the Western Cape, 2018)
In recent years, nitric oxide (NO) has emerged as an important endogenous plant
signalling molecule that mediates many developmental and physiological
processes. NO regulates the activity of antioxidant enzymes in response ...
