Meta-analysis with application to estimating combined estimators of effect sizes in biomedical research.
(2018)Meta-analysis is a statistical analysis that combines results from different independent studies. In meta-analysis a number of statistical methods are currently used for combining effect sizes of different studies. The ... -
Metabolic complications of antiretroviral therapy (ART) in a South African black population..
(2014)Aims To determine the prevalence and incidence of lipodystrophy (fat distribution [lipoatrophy and lipohypertrophy] and metabolic complications [insulin resistance-dysglycaemia and dyslipidemia]) in HIV-1 infected adult ... -
The metabolic fate of sucrose in intact sugarcane internodal tissue.
(2000)The study was aimed at determining the metabolic fate of sucrose in intact sugarcane internodal tissue. Three aspects of the fate of sucrose in storage tissue of whole plants formed the main focus of the work. These were ... -
Metabolic physiology of Colubrid dietary specialists, Dasypeltis scabra and Dasypeltis inornata.
(2009)Metabolic rate (MR) and digestive duration are thermally dependant, and energy usage changes as body temperature (Tb) changes. Increased Tb during digestion causes a rapid increase in VO2 and a shorter postprandial metabolic ... -
Metabolic responses to hyperthermia in two small desert mammals, the Pygmy rock mouse, Petromyscus Collinus and the Namaqua rock mouse, Aethomys Namaquensis.
(2012)The negative consequence of recent climate change on the Earth’s biodiversity has become more evident in recent years. Some animals, due to insularity or habitat fragmentation, are unable to shift their ranges altitudinally ... -
Metadata challenges faced by producers and users of spatial data in South Africa.
(2009)A large number of spatial datasets have inconsistent and/or outdated metadata. In certain cases, metadata is entirely absent. Some spatial data producers suggest that metadata creation and maintenance is a time consuming ... -
A metagenomic insight into the role of wastewater treatment plants as potential hotspot for antibiotic resistant bacteria and antibiotic resistance genes.
(2016)Abstract available in PDF file. -

Metal powder production by pyrolysis of metal oxalates and carbonyl clusters.
(2001)Chapter One serves as an introduction to, and background information, on the thermal decomposition of metal oxalates and homonucleus carbonyl clusters. Emphasis is placed on the compounds under investigation, namely the ... -
Metalinguistic awareness in a group of KwaZulu-Natal beginner readers.
(1996)This study evaluates beginner readers on three aspects of metalinguistic awareness as measured by Metalinguistic Awareness Interview Schedule (Dreher & Zenge, 1990), the understanding of reading as a meaning-gathering ... -
Metallic nanoparticle-graphene quantum dot nanocomposites for the electrochemical detection of methyl parathion.
(2017)This work reports on the detection of methyl parathion (MP) on electrodes constructed or decorated with graphene based nanomaterials. The sensing nanomaterials used include graphene quantum dots (GQDs), metal oxide [(MO): ... -
Metaphysical freedom and determinism: an African perspective.
(2017)The study places emphasis on the critical and philosophical nature of the African concept of destiny as it relates to the problem of freedom and determinism. In light of this, it focuses on the problem of freedom and ... -
Metaphysics of race: revisiting four philosophical views.
(2022)What does race mean in post-apartheid everyday life? Is race real or an illusion? The answer to these questions lies in the idea of how race emerged and is made real in terms of racial categories. South African apartheid ... -
Metasurface based MIMO microstrip antenna with reduced mutual coupling.
(2022)In this thesis, a negative permeability (μ) metasurface is used to reduce the mutual coupling of a 2-port Multiple-Input Multiple-Output (MIMO) rectangular inset fed microstrip antenna. That was designed using the transmission ... -
Metathesis of 1-hexene over a WO3/SiO2 catalyst in a gas-phase fixed bed reactor.
(2008)The performance of a WO3/SiO2 catalyst has been investigated for the metathesis of 1-hexene in an isothermal, gas-phase fixed bed tubular reactor between 420-500°C and at latm. The reactor was fabricated from stainless ... -
Metathesis of 1-hexene over heterogeneous tungsten-based catalysts.
(2013)Olefin (alkene) metathesis can be used for the redistribution of carbon bonds to produce preferred higher range carbon number olefins (C10-C16) from low value medium chain olefins such as 1-hexene. In this study, the ... -
Metformin alleviates neuronal and renal related stress signals in diabetic C57BL/6 mice.
(2019)In recent years, diabetes has become more prevalent due to modern, demanding, and sedentary lifestyle patterns. This disease is characterised by insulin resistance and associated molecular complications. Metformin (MF) is ...
