Genomic and metabolic investigation of an unknown inborn error of leucine metabolism mimicking MCC deficiency
(North-West University, 2011)This study revolves around a family in which 4 male members have metabolic profiles similar to that of atypical 3–methylcrotonyl–CoA carboxylase (MCC) deficiency, an inborn error of leucine catabolism. This profile consists ... -
The genotoxic effect of gold nanoparticles in cultured human cells
(North-West University (South Africa), 2016)Gold nanoparticles are ultrafine particles which are being used diversely in the medical field. Despite their versatility, the toxicity research which has been conducted on these particles is incredibly limited as well ... -
Genotypic characterisation of ESKAPE pathogens from groundwater
(North-West University (South Africa), 2023)This study aimed to investigate the presence, antibiotic susceptibility profiles, and virulence genes determinants of ESKAPE pathogens isolated from water obtained from different groundwater sources of some villages of ... -
Genotypic characterization of virulent Vibrio species and their endemic bacteriophages
(North-West University (South Africa), 2019)Vibrio are gram negative curved bacteria commonly found in aquatic environments. Some species are pathogenic to humans as well as to aquatic animals and have been associated with serious public health complications in their ... -
Geo-environmental and physical risk associated with the derelict and ownerless gold mines from Transvaal- Drakensberg and Barberton Greenstone Belt Gold Fields, Mpumalanga Province, South Africa
(North-West University, 2019)Historically mines had poor reputation for addressing environmental and safety concerns during mining and at mine closure as a result historic mining areas are left with large open pits, unsealed shafts filled with water ... -
A geobotanical investigation of mountain ecosystems in Griqualand West, South Africa
(North-West University (South Africa), 2021)The Griqualand West Centre (GWC) of plant endemism harbours a unique flora of which 24 species are endemic. Heterogeneous geology, climate and topography are considered drivers of the unique flora and local endemism. ... -
The geochemical history of the sedimentary rocks of the Witwatersrand as reflected in the mineralogy of the heavy-mineral assemblage of the uranium-bearing reefs of the Central Rand Group
(Potchefstroom University for Christian Higher Education, 1990)The well-known Archaean gold deposit on the Witwatersrand is the world's principal source of this precious metal. A tectonically active hinterland comprising Archaean granite-greenstone terrane and pre-Witwatersrand ... -
Geochemical monitoring of soil pollution from the MWS-5 gold tailings facility on the Farm Stilfontein
(North-West University, 2015)The rehabilitation and restoration of degraded landscapes adjacent to gold tailings disposal facilities (TDFs) that have suffered loss of efficiency through anthropogenic forces has become a primary concern to environmental ... -
Geoconservation of abandoned goldmines and granite quarries in the Vredefort Dome World Heritage Site, South Africa
(North-West University, 2012)Since the Vredefort Dome's listing as a World Heritage Site in June 2005, the area has seen a steady increase in tourists to both the local towns of Parys and Vredefort and the Vredefort Structure. Tourists venturing into ... -
'n Geografiese ondersoek na die kleinhoewes in die munisipale gebied van Vereeniging
(1986)The uneconomical subdivision of agricultural land and the resultant changing land usage patterns in the rural-urban fringe are major problems facing many towns in the Republic of South Africa. Against this background the ... -
Geohydrological consequences associated with the post-mine closure flooding of dewatered dolomitic karst aquifers in the Far West Rand, South Africa
(North-West University (South Africa), 2015)English The thesis presents a hydrologic investigation into the effects of deep-level gold mining on the hydrogeological conditions of a fractured-karst aquifer system in the Far West Rand (FWR) goldfield, South Africa. ... -
Geohydrological impact of co-disposed coal material into an opencast pit
(North-West University, 2016)Investigations have shown that receiving water bodies, which mainly include rivers, streams and the more complicated geohydrological system, are part of the primary end receivers of harmful contaminants from identified ... -
The geohydrology and related stability of the dolomite aquifer underlying Ikageng : Potchefstroom
(North-West University (South Africa), Potchefstroom Campus, 2017)Following large scale sinkhole formation on the Far West Rand as a direct result of mining related dolomite dewatering, groundwater is now known as an important factor affecting the stability of cavernous dolomite. Ikageng ... -
