Syntheses and bio-evaluation of radioiodinated organic compounds for application in the nuclear medicine field
(North-West University (South Africa), 2000)
Malignant melanoma (skin cancer) is a common tumour and its frequency
is increasing in the general population, the incidence varying with
geographical region (John et al., 1993). It is estimated that the mortality
rate ...
Modelling atmospheric chemical transformations under South African conditions
(Potchefstroom University for Christian Higher Education, 2000)
South Africa is in the process of adapting to new social and economical structures. The government has made it clear that the creation of work and economic growth is of the utmost importance. This policy will put South ...
The study of the deterioration of Fe-Cr-Ni alloys by Mössbauer spectroscopy
(North-West University (South Africa), 2000)
Duplex stainless steels (alloys) with chromium content in the ferritic phase greater than 13% are subject to embrittlement due to hardening of the ferrite phase. Some components of the primary loops of Pressurised Water ...
Biosphere modelling of radioactive waste disposal system in a safety assessment framework
(North-West University (South Africa), 2000)
Radioactive waste is a major concern, not only in South Africa, but worldwide. South
Africa produces radioactive waste through the full nuclear fuel cycle and the application
of radioactive materials in industry, research ...
Differential urbanisation and regional policy : the case of the Gauteng Functional Metropolitan Region
(Potchefstroom University for Christian Higher Education, 2000)
Streekontwikkelingsbeleid en differensiële verstedeliking is twee fundamentele temas binne die ruimtelike beplanningsveld.
Streekontwikkelingsbeleid is veral sedert die Tweede Wêreldoorlog in Europa geïmplementeer, waar ...
The effectiveness of cysteamine as a radioprotector against cellular damage caused by fast neutrons
(North-West University (South Africa), 2000)
At the National Accelerator Centre (NAC) a high energy neutron beam is used routinely for particle radiotherapy. During treatment the chance of biological damage to normal tissue is cause for concern as severe late-reactions ...
Invloed van vog- en ligstremming op die ontwikkeling en bioproduktiwiteit van Glycine max (L) Merr. genotipes van verskillende volwassenheidsgroeperings
(North-West University (South Africa), 2000)
Trials were conducted during the 1997/98 and 1998/99 growing seasons to
determine (1) the influence of drought and low light stress on soybean
development and productivity, (2) to set up a data base to calibrate ...
The characterisation of a fenoprofen prodrug
(North-West University (South Africa), 2000)
The term "prodrug" refers to a pharmacologically inactive compound that is converted to
an active drug by a metabolic biotransformation. A nonenzymatic process, such as
hydrolysis, can activate a prodrug via several ...
Factors affecting biological nitrogen fixation as assessed by the ureide technique in Glycine max. L. (Merril) and its implication on soybean production in South Africa
(North-West University (South Africa), 2000)
Research on nitrogen fixation was limited due to the lack of a simple and accurate
means of assessing nitrogen fixation activity. The development of the ureide technique,
(Herridge et al., 1990; Herridge & Peoples, ...
