Die asimptotiese verdeling van kwadratiese vorme in onafhanklike stogastiese veranderlikes met toepassing op sekere passingstoetse
(North-West University (South Africa), 1972)In hierdie hoofstuk word daar eerstens 'n oorsig gegee van die stogastiese proses benadering tot die bepaling van die asimptotiese verdeling van sekere passingstoetsgroothede. (Sien bv. Anderson en Darling (1952); Kac, ... -
Developing an artefact for raising social engineering awareness among administrative staff
(North-West University (South Africa), 2020)Social engineering is one of the biggest cyber-security threats faced by organisations. Cyber-criminals no longer primarily aim to exploit information systems, but rather target the ‘low hanging fruit’, which is the human ... -
Applicability of analytical techniques to quantify trace metals in particulate matter for source apportionment in South Africa
(North-West University (South Africa), 2020)The impacts of atmospheric trace metal species in particulate matter (PM) on human health and the environment is well documented. Rapid advances in the development of analytical techniques used for characterisation and ... -
Water loss under controlled humidity and temperature regimes in relation to bird eggshell thickness
(North-West University (South Africa), 2020)The African Penguin (Spheniscus demersus) is an Endangered species occurring along the Indian and South Atlantic coasts of South Africa. There are many suspected causes for the precipitous decline in their numbers. Previously, ... -
Hydrogeological analysis of groundwater occurrence within the Limpopo Province
(North-West University (South Africa), 2020)Existing literature is reviewed to investigate what delineation methodologies on groundwater occurrence already exists and could be applied to specifically the Limpopo Province. Valuable lessons learned during this study ... -
Pyrolysis and gasification of coal residues derived from tetralin liquefaction of South African density separated coal
(North-West University (South Africa), 2020)The South African coal mining industry produced approximately 307 million tons of low-rank bituminous coal in 2007. The local thermo-chemical processes utilise this coal for oils, petrochemicals and steam generation. South ... -
Reflecting on the planning of green child-friendly spaces pertaining to different socio-economic gradients
(North-West University (South Africa), 2020)Ongoing urbanisation, loss of biodiversity and development pressures are exposing our children to unhealthy and unfit environments. Children of today are growing up locked indoors and afraid of the outdoor environment, due ... -
Price estimation of basket credit default swaps using numerical and quasianalytical methods
(North-West University (South Africa), 2020)The introduction of the credit derivatives in finance has facilitated the concept of credit risk transfer, together with its analysis and management. The reason is obviously due to the fact that these derivative instruments ... -
The opportunities in aligning environmental and social management systems - a South African mining case study
(North-West University (South Africa), 2020)Historic environmental pollution and degradation from mining and mining related activities has had an adverse impact on the success of mining organisations. This is mainly as a result of pressure from stakeholders (authorities ... -
Assessing atmospheric trace gas concentrations in rural areas of the North West Province
(North-West University (South Africa), 2020)Anthropogenic activities are increasing the ambient atmospheric concentrations of inorganic gaseous pollutants, which include nitrogen dioxide (NO₂), sulphur dioxide (SO₂), and ozone (O₃). These species were also included ... -
Characterization of Staphylococcus aureus from Nigeria and South Africa
(North-West University (South Africa), 2020)The detection of methicillin-resistant Staphylococcus aureus (MRSA) in wastewater system from clinical sources has posed a public health challenge in many countries worldwide. Of a greater concern is the discharge of ... -
Mineral matter in density separated coal fractions and their transformation during laboratory combustion studies
(North-West University (South Africa), 2020)Mineral matter in coal is the primary cause of ash-related problems (fouling and slagging) during the combustion of coal. It is crucial to incorporate the behaviour of mineral matter under combustion conditions into ... -
Investigation into the protection of mitochondrial disease pathology by metallothionein overexpression
(North-West University (South Africa), 2020)Mitochondrial diseases (MD), such as Leigh Syndrome (LS), present with severe neurological and muscular phenotypes in patients, but have no known cure and limited treatment options. Based on their neuroprotective effects ... -
Exploring the perceptions of Cape Town's LGBTIQ+ individuals regarding their treatment in general and during periods of disaster relief
(North-West University (South Africa), 2020)Hazard exposure and disasters are inherently social incidents that originate from social structures and social systems, which are primarily organised according to gender and sexuality. As such, the perceptions communities ... -
Study of Diplostomum (Digenea: diplostomoidea) in South Africa: diversity and effect of metacercariae on fish behaviour
(North-West University (South Africa), 2020)A large and widely distributed group of parasites within the genus Diplostomum (Digenea: Diplostomoidea) utilises a complex life cycle with life stages that parasitise freshwater snails, fish (intermediate hosts) and ... -
Urinary metabolomics investigation of Ndufs4 knockout mice
(North-West University (South Africa), 2020)Mitochondrial diseases (MDs) are the most common inborn errors of metabolism, with an estimated prevalence of approximately 1 in 5 000 live births, and are mainly caused by deficiencies of complex I (CI) of the oxidative ... -
Exposure and effects of platinum and associated metals on the aquatic ecosystems within a platinum mining region
(North-West University (South Africa), 2020)Platinum group elements are precious metals that occur in nature only in trace concentrations. These metals are indispensable for humans due to their unique catalytic properties while they are also resistant to corrosion. ... -
Star formation histories of brightest group galaxies in CLoGS
(North-West University (South Africa), 2020)An important component of galaxy formation and evolution studies, is to accurately constrain the star formation histories (SFHs) of galaxies. While the SFHs of most massive early-type galaxies can be described using a ... -
Distribution of Mantodea in South Africa and biological studies of selected species
(North-West University (South Africa), 2020)Despite human fascination with the Mantodea or praying/preying mantids over millennia, very little is known about of their diversity, biology and ecology, especially in South Africa. Praying mantids are not only important ... -
Ecotoxicological effect of CdTe quantum dots on Eisenia andrei
(North-West University (South Africa), 2020)Nanotechnology is a modern developing discipline producing a large quantity of consumer products, likely resulting in waste materials during the upcoming decades. Engineered nanoparticles with unique physicochemical ...
