Evaluating cape honey bee sperm quality and the in vitro effect of miticides on sperm functionality and structure
(University of Western Cape, 2021)
Apis mellifera (honey bees) are essential pollinators and thus considered a keystone species. Reproductive success is therefore important to the survival of the species, with drone sperm quality playing a vital role in ...
Analysis of the structural geology of the high-grade metamorphic rocks in part of the Kakamas terrane of an area adjacent to the Neusspruit shear zone South of the orange river, Northern Cape, South Africa
(University of the Western Cape, 2021)
The Proterozoic Namaqua-Natal Province comprises highly deformed rocks of medium to high grade metamorphism and is bordering the Archean Kaapvaal Craton to the west, south and east in South Africa. The sector to the west ...
Disentangling star formation and AGN activity in the GAMA (G23) region
(University of the Western Cape, 2021)
Observations of galaxies at di↵erent wavelengths have shaped our understanding of their
formation and evolution through time. The commonly derived parameters, such as stellar
mass and star formation rate (SFR), rely on ...
Optical and microarray silver-gold based sensors for the detection of e.coli 0157:h7 in seawater
(University of the Western Cape, 2021)
Recently researchers reported that nanoparticles functionalised through chemical methods possess risks to the environment and to the human health since they use hazardous chemicals and produce toxic waste. The increasing ...
Signalling molecule “calcium” improves germination and growth of Sorghum bicolor seedlings under salt stress
(University of the Western Cape, 2021)
Abiotic stress, mainly in the form of extreme temperatures, drought and salinity has caused major crop losses worldwide, putting a severe strain on agriculture. Salinity severely limits plant growth and productivity and ...
The impact of nanoparticles on the proteome of cultured human cells
(2021)
Living organisms are constantly being exposed to nanoparticles (NPs) in the environment via air,
water, soil. Routes of exposure are usually in the form of industrial, occupational exposure, as well
as therapeutic ...
The use of derivative analysis and aquifer parameter estimation to refine a conceptual model: A case study approach, Western Cape, South Africa
(University of Western Cape, 2021)
Hydrogeological characterization of an aquifer system is a first step to determine groundwater quantity, yield potential, socio-economic value, storage capacity and aquifer transmissivity properties of an aquifer as a water ...
Photovoltaic and gas sensing applications of transitional metal nanocomposites of poly(3-hexylthiophene)-titanium dioxide
(University of Western Cape, 2021)
This thesis starts with the reviewing of studies on the loading of noble metals and nanostructured metal oxides into bulk heterojunction organic solar cell device architectures. The reviews focused on the innovative ...
Tin-oxide thin films by thermal oxidation
(University of Western Cape, 2021)
Tin dioxide (SnO2) thin films are a worthy candidate for an electron transport layer (ETL) in
perovskite solar cells, due to its suitable energy level, high electron mobility of 240 cm2 v-1 s-
1, desirable band gap of ...
A comparative evaluation of 3d and spatio-temporal deep learning techniques for crime classification and prediction
(University of Western Cape, 2021)
This research is on a comparative evaluation of 3D and spatio-temporal deep learning
methods for crime classification and prediction using the Chicago crime dataset, which
has 7.29 million records, collected from 2001 ...
