Potamanautes warreni biomarker assays to monitor silver nanomaterial contaminants in aquatic environments
(University of the Western Cape, 2016)
There has been extensive growth in nanoscale technology in the last few decades to such a degree that nanomaterials (NMs) have become a constituent in a wide range of manufactured commercial and domestic products. This ...
Nuclear level densities and gamma-ray strength functions in Ta isotopes and nucleo-synthesis of ¹⁸ᴼTa
(University of the Western Cape, 2016)
Most stable and extremely low abundance neutron deficient nuclei with Z ≥ 34 are referred to as p-nuclei. Nearly all p-nuclei with A < 110 are most likely produced in the rp-process while almost all A > 110 are thought ...
The effects of environment on radio-loud AGN activity in Stripe 82
(University of the Western Cape, 2016)
We investigate the link between environment and radiative accretion efficiency using a sample of 8946 radio-loud AGN detected at 1 − 2 GHz in the SDSS Stripe 82 region. We quantify their environments using the surface-density ...
Hydrogen storage in Ti-based coatings and Ti6Al4V alloy
(University of the Western Cape, 2016)
Hydrogen has been regarded as an ideal energy carrier for future, it can be stored as a liquid in cryogenic tanks, a gas in high pressure cylinders and as solid in metal hydrides. Hydrogen storage in metal hydrides is of ...
Mathematical modeling of the population dynamics of tuberculosis
(University of the Western Cape, 2016)
Tuberculosis (TB) is currently one of the major public health challenges in South Africa, and in many countries. Mycobacterium tuberculosis is among the leading causes of morbidity and mortality. It is known that tuberculosis ...
An analysis of sustainability of communally-managed rural water supply systems in Zimbabwe
(University of the Western Cape, 2016)
Sustainability of rural water supply systems is a major development challenge in most
developing countries including Zimbabwe. This thesis aimed to analyse the sustainability of
communally managed rural water supply systems ...
Biodiscovery of Novel Bioactivities from the South African Marine Environment
(University of the Western Cape, 2016)
There is currently a global health crisis taking place, which is the increasing
occurrence of drug-resistant pathogens within clinical microorganisms. Drugresistant
pathogens are increasingly becoming more difficult to ...
Green Synthesis and characterization of gold Nanoparticles using Green Alga Ulva Lactuca and evaluation of their Catalytric Role
(University of the Western Cape, 2016)
Nanoparticles synthesized using typical chemical procedures have associated environmental risks
because of the use of hazardous chemicals. With the ever-increasing potential application for
nanomaterials, there is a growing ...
A comparative analysis of long-term variations of temperature and rainfall in rural and urban areas, and their effects on the estimation of design storms in Kenya
(University of the Western Cape, 2016)
My Thesis aimed at expanding the current knowledge on how variations of temperature
characteristics including the possible existence of urban heat islands (UHI) over urban areas
of Kenya could be influencing rainfall ...
Exogenous caffeic acid alters molecular responses in Salvia hispanica L.
(University of the Western Cape, 2016)
Salt stress is one of the most important abiotic stresses, resulting in the
accumulation of ROS, which amount to great agricultural losses by influencing
plant yield and in turn threaten sustainable agriculture and food ...
