Antimicrobial activity of South African red algal secondary metabolites
(UWC, 2001)
Infectious diseases, for example, measles, scarlet fever, malaria, tuberculosis, and cholera have claimed many lives. These infections are caused by pathogenic viruses, bacteria, or fungi that invade the body's tissues and ...
The influence of maternal nicotine exposure on neonatal rat trachea development and alveoli status
(University of the Western Cape, 2000)
The aim of this study was to determine the effect of maternal nicotine exposure on
the status of the rat tracheal development as well as the rat lung of 7 to 42 day old
offspring. Wistar dams were injected subcutaneously, ...
Spin and parity assignment in 152gd investigating octupole structures
(University of the Western Cape, 2008)
Spin and parity assignment in 152gd investigating octupole structures
The high-spin states of the nucleus ls2cd have been populated via the ls2sm (cr, 4n)
152Gd fusion-evaporation reaction at abeam energy of 45MeV. The ...
Calibration of germanium detectors for applications of radiometric methods in South Africa.
(University of the Western Cape, 2001)
AII materials that are radioactive emit characteristic gamma-radiation. Natural radioactivity
can be used in heavy minerals exploration and processing, as well as in understanding
sediment transport. processes in coastal ...
Intense pulsed neutron generation based on the principle of plasma immersion ion implantation technique (PIp3s) technique
(University of the Western Cape, 2006)
The development of a deuterium deuterium/ tritium-deuterium (D-D/ D-T) pulsed neutron generator based on the principle of the Plasma Immersion Ion Implantation 1Pl) technique is presented, in terms of investigating development ...
Study of the use of Electret Ion chambers as radom dosimeters in South Africa
(University of the Western Cape, 2002)
Radon is a naturally occuring radioactive gas which has been shown to be a major contribution to background dose. The underground mines in South Africa present a major occupational hazard. A need for cheap personal monitoring ...
A case study of university students' experiences of introductory physics drawn from their approaches to problem solving
(University of the Western Cape, 2001)
This thesis explores the experience of leaming physics through a particular medium: problem-solving, which is seen by many educators as the primary medium in which physics is learnt at university. Situating itself within ...
Inclusive (p, α) and (p,³He) cross sections induced by 100 MeV protons on ⁴⁰Ca
(University of the Western Cape, 2006)
Alpha clusteri ng in nuclei is studied with quasi - free knockout reactions. A beam of 100 MeV polarized protons was used in the quasi-free knockout reaction 40 ~a( p,p' a)36 Arat iThemba LABS. While the scattered protons ...
Measurements and applications of radon in South African aquifer and river waters
(University of the Western Cape, 2009)
In the natural decay series of 238Uan inert radioactive gas, 222Rn(radon) is formed in the decay of 226Ra.Because radon is relatively soluble in water, it migrates from places of its generation in rocks and soils to other ...
Using internet -enabled remote instrumentation for research and training in physics: Evaluation of different diffusion barriers for silver metallization
(University of the Western Cape, 2007)
The growth of the Internet has led to many interesting developments for both educational and commercial purposes. In this project an attempt was made to use the Internet for a research purpose to facilitate the determination ...
