  • De Bosscher, Karolien   Van den Berghe, Wim   Beck, Ilse M. E.   Van Molle, Wim   Hennuyer, Nathalie   Hapgood, Janet   Liber, Claude   Staels, Bart   Louw, Ann   Haegeman, Guy (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 ...
  • Bailly, Nathalie (Stellenbosch : Stellenbosch University, 2008-12)
    The Reversible addition fragmentation chain transfer (RAFT) technique is a robust and versatile technique that enables the synthesis of polymers of controlled molecular weight and polydispersity. The application of the ...
  • Venter, Gerhard (Gerhard Abraham) (Stellenbosch : Stellenbosch University, 2002-12)
    ENGLISH ABSTRACT: A thorough search through the literature as well as through the Cambridge Crystallographic Structural Database resulted in no examples of a neutral ozone acting as ligand in a complex with any metal. ...
  • Maleri, Rudolf A. (Stellenbosch : University of Stellenbosch, 2006-12)
    Metals are natural elements of the earth crust usually present at low concentrations in all soils. Although many metals such as cobalt, copper, iron and zinc are essential to living organisms, at elevated concentrations ...
  • Robertson, Steven   Allie-Reid, Fatima   Vanden Berghe, Wim   Visser, Koch   Binder, Anke   Africander, Donita   Vismer, Michael   De Bosscher, Karolien   Hapgood, Janet   Haegeman, Guy   Louw, Ann (HighWire Press, 2010-03)
    Compound A (CpdA), a dissociated glucocorticoid receptor modulator, decreases corticosteroid-binding globulin (CBG), adrenocorticotropic hormone (ACTH), and luteneinizing hormone levels in rats. Whether this is due to ...
  • Albertyn, Chris (Stellenbosch : Antarctic Legacy Project, 2011-10-05)
    Film footage of the accident at sea in which Petty Officer Bold lost his life. The men were transporting goods to be offloaded on the Marion Island coast and the boats capsized.
  • Deere, Jacques Andries (Stellenbosch : Stellenbosch University, 2005-12)
    ENGLISH ABSTRACT: Evidence for widespread ecological impacts due to rapid climate change is on the increase, with further warming predicted over the next century. This increase in warming has lead to organisms adjusting ...
  • Bauer, Rolene (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: Wine quality is compromised by the presence of 3-hydroxypropionaldehyde (3-HPA) due to spontaneous conversion into acrolein under wine making conditions. Acrolein is highly toxic and is presence has ...
  • Thomas, Mark Peter (Stellenbosch : Stellenbosch University, 2008-12)
    Cells are equipped with an array of adaptive mechanisms to contest the undesirable effects of ischemia and the associated hypoxia. Indeed, many studies have suggested that there is an increase in the PI3K/Akt pathway ...
  • Coetzee, Liezel (Stellenbosch : Stellenbosch University, 2001-12)
    ENGLISH ABSTRACT: This study concerns the incorporation of adamantane containing monomers 3-(1-adamantyl)-1-propene and 1-(1-adamantyl)-4-vinylbenzene into ethene, propene and higher a-olefins using different catalytic ...
  • Pretorius, Eugene (Stellenbosch : University of Stellenbosch, 2008-03)
    In this paper, tracking tools are developed based on object features to robustly track the object using particle filtering. Automatic on-line initialisation techniques use motion detection and dynamic background modelling ...
  • Joubert, Daniek (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: In this thesis we consider the problem of building a dense and consistent map of a mobile robot’s environment that is updated as the robot moves. Such maps are vital for safe and collision-free ...
  • Rohwer, Christian M. (Stellenbosch : University of Stellenbosch, 2010-12)
    ENGLISH ABSTRACT: Due to the minimal length scale induced by non-commuting co-ordinates, it is not clear a priori what is meant by a position measurement on a non-commutative space. It was shown recently in a paper by ...
  • Anderson, Bruce (AOSIS OpenJournals, 2010-08)
    The new ‘African dinosaurs’ exhibit at the Iziko South African Museum in Cape Town capitalises on a fascination that almost every person – old and (especially) young – has with dinosaurs. A highway into the human ...
  • Makunga, Nokwanda P. (AOSIS OpenJournals, 2011-10)
    In the past few years, African medicinal plants have received considerable attention, and it has been lamented that the documentation of the continent’s species that are used in traditional medicine lags behind China and ...
  • Rajaona, Solofomampionona Fortunat (Stellenbosch : Stellenbosch University, 2013-03)
    ENGLISH ABSTRACT: Stepwise development of a program using refinement ensures that the program correctly implements its requirements. The specification of a system is “refined” incrementally to derive an implementable ...
  • Van Wilgen, Nicola J.   Richardson, David M.   Baard, Ernst H. W. (Academy of Science of South Africa -ASSAf, 2008-02)
    Biological invasions are a growing problem in South Africa. Many alien species have been introduced for various reasons and through multiple pathways over the past few centuries. Invasive alien reptiles and amphibians ...
  • Lee, Jennifer Elizabeth (Stellenbosch : University of Stellenbosch, 2009-03)
