  1. Characterising the Namaqualand Mudbelt: Chronology, Palynology and Palaeoenvironments : Chapter 2
    Gray, Catherine Elizabeth Darnell, 2009, University of Cape Town Libraries
    This multiproxy study explores the palaeoenvironmental record of two cores, H2 and H7, from the Namaqualand Mudbelt representing an arid and highly variable landscape. As bulk organic radiocarbon ages previously proved problematic, with anomalous reversals, the primary objective was to improve chron ...

  3. Rape crisis concellor"s experience of working with rape survivors in Cape Town
    Gregorowski, Claire, 2010, University of Cape Town Libraries
    This exploratory qualitative study documents the clinical knowledges gained by Rape Crisis counsellors working with rape survivors in Cape Town. It includes a description of the demographic profile of their clients, the rape experiences that their clients report, the psychological difficulties that ...
  4. Large vegetated termitaria and fire impacts on reptilitan community assemblage in a miombo woodland system heavily impacted by elephants
    Heermans, Ben Cooper, 2010, University of Cape Town Libraries
    Habitat change is the principal cause of wildlife population declines worldwide. Elephant densities have altered the vegetation structure in many southern African reserves which, combined with the affect of fire and anthropogenic disturbances, have enormous consequences for biodiversity and faunal c ...
  5. The impact of Psychosocial Stress and Biological Sex on False Recognition Memory
    Henry Michelle, 2010, University of Cape Town Libraries
    Based on the premise that both the hippocampus and pre-frontal cortex are affected by cortisol and involved in declarative memory processes, the current research aimed to confirm that psychosocial stress can lead to increased rates of false recognition memory errors in humans. In addition, it attemp ...
  6. Determination of Neutron Energy Spectra inside a water phantom irradiated by Neutrons of Energy up to 64 MeV : Title Page, Abstract, Table of Contents
    Herbert, Mark, 2009, University of Cape Town Libraries
    A neutron spectrometer based on an NE230 deuterated organic liquid scintillator (25 mm diameter x 25 mm) has been developed for measuring neutron spectra in water. The spectrometer is capable of measuring neutron energies above 5 MeV, set by the electronic threshold. An important feature of the spec ...
  7. Investigating the role of IL-4/IL-13 and their receptors in ulcerative colitis
    Hoving, J Claire, 2010, University of Cape Town Libraries
    Ulcerative colitis (UC) is a heterogeneous inflammatory bowel disease (IBD) associated with chronic inflammation of the gastrointestinal tract. Characterized by genetic and immunological abnormalities, UC has overly aggressive T-cell responses to commensal bacteria eventually leading to disease path ...
  8. Analyzing sustainable energy in developing countries: Selected South African case studies
    Howells, Mark Idwal, 2008, University of Cape Town Libraries
    This thesis demonstrates the use of selected Energy-Environment-Economic (E3) modelling techniques to provide insight to developing country issues. The work focuses on analyzing combinations of technologies and energy use to satisfy potential requirements of consumers at the lowest cost to society. ...
  9. The impact of Acute Psychological Stress on declarative memory functioning
    Human, Robyn, 2010, University of Cape Town Libraries
    Previous research has shown that stress affects processing in many different memory systems. This study aimed to investigate the effects of acute psychosocial stress on declarative memory (DM) and working memory (WM) performance, and to explore whether sex differences exist under stress in these two ...
  10. Foundation of relative non-abelian homological algebra
    Janelidze, Tamar, 2009, University of Cape Town Libraries
    We consider pairs (C;E), where C is a pointed category and E a class of regular/normal epimorphisms in C, satisfying various exactness properties. The purpose of this thesis is: 1. To introduce and study suitable notions of a relative homological and a relative semi- abelian category. In the absolut ...
