Comparative study on the molecular structure of ethylene/1-octene, ethylene/1-heptene and ethylene/1-pentene copolymers using advanced analytical methods
(Stellenbosch : Stellenbosch University, 2015-04)
ENGLISH ABSTRACT: Linear low density polyethylene (LLDPE), one of the fastest growing types of polyethylene, is made from the copolymerisation of ethylene and higher 1-olefin comonomers. 1-octene is the comonomer of choice ...
From stable priors to maximum Bayesian evidence via a generalised rule of succession
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: We investigate the procedure of assigning probabilities to logical statements. The simplest
case is that of equilibrium statistical mechanics and its fundamental assumption of
equally likely states. ...
The effect of in-process ethylene incorporation on the evolution of particle morphology and molecular characteristics of commercial heterophasic ethylene propylene copolymers (HEPCs)
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Impact copolymers or heterophasic polypropylene-ethylene-co-propylene copolymers (HEPCs) commonly produced in industry are valued for their good mechanical properties, combining the rigidity of the ...
The evolution of fynbos-endemic Cephalelini leafhoppers specialising on Restionaceae
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Knowledge of the diversity and evolutionary histories of insects in South Africa’s fynbos biome lags far behind what is known of the plant groups that make up this global biodiversity hotspot. To address ...
Hyperglycemia-mediated onset of myocardial insulin resistance – unraveling molecular mechanisms and identifying therapeutic targets
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Background - Although acute hyperglycemic episodes are linked to lower glucose uptake, underlying mechanisms driving this process remain unclear. We hypothesized that acute hyperglycemia triggers reactive ...
Androgen controlled secondary sexual characters in the male African clawed frog, Xenopus laevis, as potential biomarkers for endocrine disruptor contaminants (with special reference to fungicides) in aquatic systems
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Endocrine disrupting contaminants (EDCs) coming from households, industrial parks, wastewater (sewage) treatment and agricultural areas have been shown to pollute our freshwater systems. These contaminants ...
Grain regression analysis
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Grain regression analysis forms an essential part of solid rocket motor simulation.
In this thesis a numerical grain regression analysis module is developed
as an alternative to cumbersome and time ...
The synthesis of novel kinase inhibitors using click chemistry
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Cancer is the leading cause of death on the planet, killing an estimated 8.2 million people in the year of 2012.The disease is associated with two families of genes, namely oncogenes and tumour suppressor ...
The design and synthesis of novel HIV-1 non-nucleoside reverse transcriptase inhibitors
(Stellenbosch : Stellenbosch University, 2015-04)
ENGLISH ABSTRACT: Since its discovery in the 1980’s, HIV has affected the lives of millions of individuals around the
globe. Despite obvious need and an enormous amount of research a cure has remained elusive
due to the ...
Comprehensive two-dimensional liquid chromatographic analysis of anthocyanins
(Stellenbosch : Stellenbosch University, 2015-04)
ENGLISH ABSTRACT: Anthocyanins are naturally occurring pigments responsible for the colour of many natural products,
including grapes and wine. These pigments are important to the food industry and have been
recognised ...
