Imprints of Primordial Non-Gaussianity on Large Scale Structure in the Universe
(University of the Western Cape, 2016)
Large scale structure in the universe is one of the most important probing tools for
cosmological modelling. Assuming the hot big bang model of the universe, the expansion
history has undergone two phases of acceleration. ...
Optical and electronic properties of methylammonium lead halide perovskite solar cells
(University of the Western Cape, 2017)
Organic-inorganic hybrid perovskite solar cells have emerged as promising materials for next-generation
photovoltaics with certified efficiency of 22.1%. Despite rapid developments, achieving precise control
over the ...
Intra- and inter-population variation in the bladder grasshopper Bullacris unicolor
(University of the Western Cape, 2014)
Although the processes that promote biodiversity and speciation remain poorly understood, ecological factors are thought to be one of the causal agents responsible for promoting variation. Bladder grasshoppers (Orthoptera; ...
A Comprehensive Study on the Global Regulatory Requirements for the submission of a Post-Approval Change, specifically a Change in Manufacturing Site
(University of the Western Cape, 2017)
Regulatory requirements for post-approval changes vary for different countries around
the world. It is a challenging and costly process for pharmaceutical companies to
manage changes to the approved regulatory dossier over ...
Coastal marine heatwaves: Understanding extreme forces
(University of the Western Cape, 2017)
Seawater temperature from regional to global scale is central to many measures of biodi-
versity and continues to aid our understanding of the evolution and ecology of biolog-
ical assemblages. Therefore, a clear understanding ...
Hydrological Characterisation of Wetlands: Understanding wetlands-catchment linkages
(University of the Western Cape, 2017)
This study explores the hydrological processes of selected wetlands in four different catchments in South Africa (the Nuwejaars River in the Western Cape which has the Elandsdrift-Wiesdrift wetland; the Mohlapetsi river ...
Synthesis of metal modified Mesoporous Zeolites catalysts: application in conversion of Olefins to Valuable liquid products
(University of the Western Cape, 2016)
The effects of temperature, synthesis duration and silica source were studied to obtain
suitable conditions for our laboratory experiment concerned with the synthesis of MCM-41
catalyst. The transformation of 1-hexene was ...
Synthesis, characterization and catalytic application of carbonyl complexes of molybdenum and tungsten in epoxidation of some alkenes
(University of the Western Cape, 2010)
In this thesis we describe the synthesis of several carbonyl complexes of molybdenum and tungsten, compounds (Cl-ClO). The compounds Cl- C4 are zero valent carbonyl complexes containing N-base ligands prepared by following ...
Gallic acid modulates salt stress tolerance in soybean plants by regulating antioxidant capacity
(University of the Western Cape, 2017)
Soybean [Glycine max L (mer)] is one of the top commodity crops in the world
including South Africa (de Beer and Prinsloo, 2013). These small yet important
podded legumes are a great source of protein and are used in many forms.
Determining the Spectroscopic Quadrupole Moment Qs of the 2+1 state in 40Ar
(University of the Western Cape, 2017)
The rst reorientation-e ect Coulomb-excitation experiment has been
performed at iThemba LABS by bombarding 40Ar beams on a heavy
208Pb target at a \safe" energy of Elab =143.2 MeV. The goal was to
determine, the spectroscopic ...
