The effect of organic peroxides on the molecular composition of heterophasic ethylene-propylene impact copolymers
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Heterophasic ethylene-propylene copolymers, also known as impact polypropylene (PP) copolymers (IPCs) or heterophasic copolymers (HECOs), are a unique group of polyolefins produced through the copolymerisation ...
Constructing dualities from quantum state manifolds
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: A constructive procedure to build gravitational duals from quantum mechanical
models is developed with the aim of studying aspects of the gauge/gravity duality.
The construction is simplified as far as ...
Analysis of Extreme Events in the Coastal Engineering Environment
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT : Coastal zones are subject to storm events and extreme waves with certain return
periods. The return period of such events is defined as the average time interceding
two independent, consecutive events, ...
Synthetic porous materials : a study of adsorption selectivity and structure-property relationships
(2015-12)
ENGLISH ABSTRACT: The aim of this thesis was to study structure-property relationships in porous materials using various adapted analytical techniques and in-house instruments. The thesis is divided into two sections, and ...
Novel multinuclear complexes of Rh and Ru and their application in alkene hydroformylation
(Stellenbosch : Stellenbosch University, 2015-11-25)
ENGLISH ABSTRACT: This project entailed the synthesis and characterization of mono- and multi-nuclear rhodium
and ruthenium iminopyridyl complexes and their application in the hydroformylation of 1-
octene. The multi-nuclear ...
The regulation of Phosphoenolpyruvate (PEP) metabolism via Phosphoenolpyruvate Carboxylase (PEPC) in P-deficient roots and nodules of Virgilia divaricata
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Plants exhibit a flexible array of morphological, physiological and biochemical adaptations during
phosphorous limitation. Legumes are vulnerable to P deficiency, because it affects their ability to
fix ...
Studies in the synthesis of benzoxazole compounds
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Benzoxazoles are an important class of π-electron-excessive, benzene-fused heterocyclic
compounds found in natural products and display a wide range of pharmacological applications.
It is therefore a ...
Fouling by non-indigenous marine species - impacts on biodiversity and mariculture
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Alien fouling species are most likely to be introduced into Saldanha Bay via two vectors: the high shipping volume experienced in the Bay and the intensive mariculture operations that take place in the ...
Determination of the bacterial diversity of a natural freshwater wetland impacted by acid mine drainage.
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Freshwater resources in semi-arid countries, such as South Africa, are under constant threat
from pollution. One of the major pollutants is acid mine drainage, which not only lowers the
pH of the water, ...
Synthesis and structure-property relationships of 3-methylene-2-pyrrolidone-based (co)polymers
(Stellenbosch : Stellenbosch University, 2015-03)
ENGLISH ABSTRACT: Recently, the incorporation of renewable resources as a substitute to fossil fuels in the synthesis of polymers/materials has attracted a vast amount of interest, particularly for the green advantages ...
