(North-West University, 2017)This thesis, with the title "A metabolomics investigation of in utero antiretroviral exposure to neonates", deals with the concern over adverse metabolic consequences reported for some neonates prenatally exposed to ... -
An investigation into maser variability in high-mass star forming regions
(North-West University, 2018)The two brightest class II methanol masers - at 6.7- and 12.2-GHz, are exclusively associated with the early phases of high-mass star formation. This implies that studying these maser species is an indirect probe of the ... -
Fusarium verticillioides infection and fumonisin synthesis as affected by maize plant stressors
(North-West University, 2017)Fusarium verticillioides is an important ear rot pathogen of maize that can lead to economic losses due to yield and grain quality reduction. Symptoms vary depending upon genotype, environment and disease severity. F. ... -
Effects of Dolerite Intrusions on the geohydrology of Karoo sediments in the Mount Frere area, South Africa
(North-West University, 2017)The Karoo Supergroup has a geohydrological regime which is largely controlled by Jurassic dolerite dyke and sill complexes. The study area is located in the central interior of the Eastern Cape Province, in the former ... -
A molecular study of the causal agent of bacterial leaf streak disease
(North-West University, 2016)Bacterial leaf streak disease (BLSD) of maize is caused by the pathogen currently classified as Xanthomonas campestris pv. zeae. The disease has only been reported in South Africa and is a potential threat to commercial ... -
The feasibility of alternative fuels to reduce air emissions from South African cement production
(North-West University, 2017)The research aims to determine the feasibility of alternative fuel co-processing to reduce kiln stack emissions and focussed on the calculation of possible reductions in these emissions when substituting one tonne of ... -
