Characterisation of the uranium tetrafluoride unburnt materials using non-destructive assay techniques for safeguards purposes
(North-West University (South Africa), 2020)Inspectors use non-destructive assaying (NDA) techniques for verification measurements of safeguarded nuclear materials. The NDA techniques help the International Atomic Energy Agency to verify all declared nuclear materials ... -
Purposeful covariate selection methods for parsimonious binary logistic regression models
(North-West University (South Africa), 2020)Most previous studies have applied the covariate selection method proposed by Hosmer and Lemeshow (2000) (also referred to in the current study as the Hosmer and Lemeshow algorithm (H-L algorithm)) in attempt to fit ... -
Optimising the dissolution of U/ Al in alkaline solutions and subsequent dissolution of the generated uranium residue in nitric acid
(North-West University (South Africa), 2019)SAFARI-I reactor is a "tank-in-pool" high flux reactor that is situated in Pelindaba, South Africa. The SAF ARI-1 is a material testing reactor that uses LEU target plates, containing 19% uranium enrichment. When producing ... -
Conservation laws and exact solutions of Kudryashov-Sinelshchikov equation and Benney-Luke equation
(North-West University (South Africa), 2017)In this dissertation we study two nonlinear partial differential equations namely; the Kudryashov-Sinclshchikov equation and the Benney-Luke equation. We employ the multiplier method to find conservation laws and Kudryashov ... -
Direct quantitative gross aB-measurements of environmental water contaminated with nuclides from the uranium, thorium and actinium decay series and semi-qualitative identification of nuclides concerned.
(North-West University (South Africa), 2011)Naturally occurring radioactive materials (NORMs) in environmental samples are of crucial importance in the case of radiological impact studies in any environmental compartment. For this reason, valuable information is ... -

(North-West University (South Africa), 2019)The use of non-conventional feedstuffs has the potential to sustainably intensify poultry production in resource-poor communities of South Africa. Red grape pomace (GP) is a feed resource that is rich in beneficial bioactive ... -
Recombinant expression and functional characterization of a putative pentatrico-peptide protein from Arabidopsis thaliana
(North-West University (South Africa), 2012)Food security appears to be heavily dependent on the development of crop plants with increased resistance to both biotic and abiotic stresses such as pathogen infections and droughts respectively. Plant biotechnology has ... -
Recombinant expression and functional characterization of a fusion F-box protein from A. thaliana
(North-West University (South Africa), 2012)Adenylate cyclases (A Cs) are enzymes that are capable of converting adenine-5'-triphosphate (ATP) to cyclic 3', 5'-adenosine monophosphate (cAMP). It has been found that cAMP has an important role in cell signalling and ... -
