This indicates that very limited research has been done in the field of business journa ...
  2. A new continuum mapping procedure at HartRAO
    Büchner, Sarah, 1998
    A basket weaving technique for making radio continuum maps has been developed at the Hartebeesthoek Radio Astronomy Observatory (HartRAO). This data reduction technique significantly reduces scanning effects by using independent maps scanned in orthogonal directions. The observation and data analysi ...
  3. The analysis of the strain level and the predicted human error probability for critical hospital tasks
    Burford, Eva-Maria, 2012
    South African hospitals, as a result of numerous factors, have the problem of an increasing workload for nursing staff, which in turn may affect patient treatment quality. This project aimed at addressing patient treatment quality specifically from the perspective of worker capabilities by investiga ...
  4. Synthetic and bioactivity studies of antiplasmodial and antibacterial marine natural products
    Young, Ryan Mark, 2011
    This thesis is divided into two parts, assessing marine and synthetic compounds active firstly against Plasmodium falciparum (Chapter 3 and 4) and secondly active against methicillin resistant Staphylococcus aureus (MRSA, Chapter 5). In Chapter 3 the synthesis of nine new tricyclic podocarpanes (3 ...
  5. The effect of environmental factors and hormone treatments on ovulation rate and spawning success in cardinal tetras, Paracheirodon axelrodi (Pisces: Characidae)
    Burton, Simon Mark, 1998
    Cardinal tetras, Paracheirodon axelrodi (Pisces: Characidae), are among the most popular tropical ornamental fish in the world. Millions of cardinal tetras are removed from their natural habitat, the upper tributaries of the Rio Negro in Brazil, each year and exported to North America and Europe whe ...
  6. Asymmetric induction in reactions of chiral carboxylic esters and silyl enol ethers
    Evans, Melanie Daryl, 1998
    Several camphor and pinane derivatives have been synthesised and evaluated for use as chiral auxiliaries in asymmetric synthesis. Various blocking groups have been attached to the camphor skeleton in attempts to improve stereofacial selectivity; these include a-methoxybenzyl and xylyl groups, and no ...
  7. An exploration into self-extending systems in early literacy in English of Grade One isiXhosa speaking learners
    O"Donoghue, Elizabeth Lindsay, 2012
    The purpose of this research was to explore the ways in which a small, purposefully sampled group of Grade One isiXhosa-speaking children began the process of becoming literate in English as their second language. The research looked specifically for evidence of strategic behaviours in reading and ...
  8. Growth, reproduction and feeding biology of Turbo sarmaticus (Mollusca: Vetigastropoda) along the coast of the Eastern Cape Province of South Africa
    Foster, Gregory George, 1997
    Investigations were carried out on aspects of the biology of the vetigastropod Turbo sarmaticus. Studies included: I) the distribution and standing stock of this animal at four sites along the coast of the Eastern Cape Province of South Africa; 2) the growth rate of animals on a wave-cut platform; 3 ...
  9. Aspects of renormalisation in some quantum field theories
    Roy, Alan A., 1997
    Renormalisation is an important aspect of Quantum Field Theory. It is used to create physically meaningful theories and some major developments took place in the 1970"s and onwards. We consider Renormalisation in its application to the theories of ψ⁴ , Quantum Electrodynamics, Quantum Chromodynamics ...
  10. Ecological interactions on a rocky shore : the control of macroalgal distribution by intertidal grazers
    Whittington-Jones, Kevin John, 1997
    The aim of the present study was to detennine the potential impact of intertidal grazers on the distribution of macro algae on the south coast of South Africa. Particular attention was paid to the large patellid limpet, Patella oculus, which is found thoughout the intertidal zone. Studies of gut ...
