2020-12-31 Thermal biology of the invasive ladybird Harmonia axyridis : physiological plasticity, thermoregulatory behaviour and fitness
(Stellenbosch : Stellenbosch University, 2014-12)ENGLISH ABSTRACT: Physiological and behavioural responses to changes in temperature may enable ectotherms to buffer the effects of climate change or facilitate movement into novel environments. The thermal biology of the ... -
36 Chlorine isotope systematics in saline groundwater in the Buffels River Valley
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: It is typical for coastal aquifers in arid regions to be affected by salinisation, populations in these areas that rely upon groundwater resources are often directly afflicted by this phenomenon. Large ... -
3D numerical techniques for determining the foot of a continental slope
(Stellenbosch : Stellenbosch University, 2004-12)ENGLISH ABSTRACT: The United Nations Convention on the Law of the Sea (UNCLOS) provides an opportunity for qualifying coastal signatory states to claim extended maritime estate. The opportunity to claim rests on the ... -
A 3D Virtual Environment Development Platform for ASD Therapy Tools
(Stellenbosch : University of Stellenbosch, 2009-12)ENGLISH ABSTRACT: The aim of this thesis is to develop a generic 3D virtual environment development platform for autism spectrum disorder (ASD) therapy tools. The potential of using computerised therapy tools for ASD ... -
50 years of Emmonsia disease in humans : the dramatic emergence of a cluster of novel fungal pathogens
(Public Library of Science, 2015)New species of Emmonsia-like fungi, with phylogenetic and clinical similarities to Blastomyces and Histoplasma, have emerged as causes of systemic human mycoses worldwide. They differ from classical Emmonsia species by ... -
A fully dissociated compound of plant origin for inflammatory gene repression
(PNAS, 2005-11)The identification of selective glucocorticoid receptor (GR) modifiers, which separate transactivation and transrepression properties, represents an important research goal for steroid pharmacology. Although the gene-activating ... -
A study on the reversible photo-induced isomerisation of platinum(II) and palladium(II) complexes of the N,N-dialkyl-N’-acyl(aroyl)thioureas with reversed-phase HPLC separation from related rhodium(III), ruthenium(III) and iridium(III) complexes
