Criteria for regulating and managing radioactive material in South Africa compared to the criteria of the ISO 14001 Environmental Management System within the mining and minerals industries
(Potchefstroom University for Christian Higher Education, 2002)
The National Nuclear Regulator Act (NNRA) (Act no 47 of 1999) and the Hazardous Substances Act (Act no. 15 of 1973): Group IV Hazardous Substances regulate the use of radioactive material in the mining and minerals processing ...
Molecular characterisation of suspected heterozygotes of trimethylaminuria
(Potchefstroom University for Christian Higher Education, 2002)
Trimethylaminuria (McKusick 602079) or Fish odour syndrome is inherited recessively
as a defect in hepatic nitrogen-oxidation of dietary derived trimethylamine (TMA), which
causes excess excretion of trimethylamine such ...
Measurement of the equilibrium factor between radon and its progeny in the underground mining environment
(North-West University (South Africa), 2002)
In an undisturbed area with little air circulation, the short-lived radon daughters will
come into equilibrium with the parent radon, that is, the concentration ( measured in
Bq / m3
) of radon in air will be equal to ...
Development of a duoplasmatron ion source at the Ithemba laboratory for accelerator based science (ithemba labs)
(North-West University (South Africa), 2002)
A cold hollow cathode duoplasmatron ion source has been designed, built, optimized and
evaluated for use as an external stand-by ion source for the second injector cyclotron
(SPC2) during those times that the light-ion ...
A project in symmetries of differential equations
(North-West University (South Africa), 2002)
The aim of the project is to discuss the non-linear wave equations whose
coefficients are dependent on first order spatial derivatives. We construct
the principal Lie algebra, the equivalence Lie algebra, and the ...
The use of ammonium sulphate as an acidiogenic agent in bone meal licks to improve the phosphorus status in cattle
(North-West University (South Africa), 2002)
Sixteen Bonsmara calves ( 4 males, 12 females) were blocked according to sex and randomly assigned to 2 groups of 8 each. They were offered licks containing bone meal and salt (control) and bone meal and ammonium sulphate ...
Design and optimisation of new beamlines for iThemba laboratory for accelerator based sciences (iThemba LABS0
(North-West University (South Africa), 2002)
The facilities at iThemba LABS are used for basic and applied research, treatment of
patients with proton and neutron beams and the production of radioisotopes for
hospitals and industry. The laboratory operates a 6 MV ...

Phosphatase activities of riverine phytoplankton in the Vaal river (South Africa) : physiological responses of nuisance species to different nutrient regimes
(North-West University (South Africa), 2002)
The theme of this thesis is the ecophysiological basis for development of massoccurrences
of phytoplankton species in aquatic environments. Research concerning
the reasons for harmful algal bloom (HAB) formation has been ...
The impact of dark chilling followed by exposure to high light intensities on ultrastructure and selected biochemical reactions of photosynthesis in Glycine Max (L.) Merrill
(North-West University (South Africa), 2002)
The impact of dark chilling on ultrastructure and key reactions of photosynthesis was
assessed in two soybean genotypes, 'Maple Arrow' and 'Fiskeby V'. Both these
genotypes are regarded as chilling tolerant (albeit ...
