Measurement and verification of the Eskom irrigation pumping standard product programme: evaluation of crop load factors
(2013)Eskom Integrated Demand Management (IDM) also included irrigation in the Standard Product Programme (SPP) to cater for smaller irrigation Energy Efficient (EE) projects. The irrigation sector is a large energy consumer ... -
Measurement uncertainty of current harmonics during the assessment of compliance to grid code requirements
(IEEE, 2018)This paper improves the impact of measurement uncertainty on harmonic grid code compliance assessment by characterization of the current transformers at a renewable power producer. Field data was collected to evaluate the ... -
Mechanical and thermal characterization of briquetted high ash South African coal fines using low density polyethylene as the binding agent
(International Pittsburgh Coal Conference, 2016) -
The mechanism by which moderate alcohol consumption influences coronary heart disease
(BioMed Central, 2015)Background Moderate alcohol consumption is associated with a lower risk for coronary heart disease (CHD). A suitably integrated view of the CHD pathogenesis pathway will help to elucidate how moderate alcohol consumption ... -
The mechanisms by which antidepressants may reduce coronary heart disease risk
(BioMed Central, 2015)Background Depression is known to increase the risk for coronary heart disease (CHD) likely through various pathogenetic actions. Understanding the links between depression and CHD and the effects of mediating these links ... -
Medium-vocabulary speech recognition for under-resourced languages
(SLTU, 2012)We report on the development of speech-recognition systems that are able to perform accurate recognition on mediumvocabulary tasks (i.e. tasks that require distinctions between approximately 200 different terms). We are ... -
Membranes with recombination catalyst for hydrogen crossover reduction: water electrolysis
(ECS, 2018)An unusual morphology of the Pt-based catalyst, embedded in a PFSA membrane matrix, is described. The catalyst was developed for reducing hydrogen gas crossover in the PEM water electrolysis process. A modified electroless ... -
Mercury removal by porous sulfur copolymers: adsorption isotherm and kinetics studies
(Elsevier, 2020)Mercury is one of the most toxic, harmful element present in water that severely affects human health. Many traditional as well as advanced technologies were developed to remove mercury from wastewater. In this study, ... -
The merits of exergy-based fault detection in petrochemical processes
(Elsevier, 2019)The complexity and multi-domain nature of petrochemical (PC) plants make the application of conventional model-based fault detection and isolation (FDI) techniques a challenging endeavour. Although hybrid FDI schemes aim ... -
Metagenomic profiling dataset of bacterial communities of a drinking water supply system (DWSS) in the arid Namaqualand region, South Africa: source (lower Orange River) to point-of-use (O'Kiep)
(Elsevier, 2019)The metagenomic data presented herein contains the bacterial community profile of a drinking water supply system (DWSS) supplying O'Kiep, Namaqualand, South Africa. Representative samples from the source (Orange River) to ... -
Metal ions adsorption affinity of clayey materials from the North West Province of South Africa
(CUMTP, 2014)Local clays that are abundant in the periphery of Potchefstroom in South Africa were characterized and investigated as potential sorbents for the removal of metal ions from effluents. The clay samples mostly contained ... -
Metal nanoparticles decorated phosphorylated carbon nanotube/cyclodextrin nanosponge for trichloroethylene and Congo red dye adsorption from wastewater
(Elsevier, 2020)In this research, insoluble nanosponge β-cyclodextrin (β-CD) polyurethane was modified with phosphorylated multiwalled carbon nanotubes (pMWCNTs) and further decorated with titanium dioxide and silver nanoparticles. This ... -
Metal retention potential of sediment and water quality in the Mooi River, South Africa
(Taylor & Francis, 2017)The potential metal retention by sediments along the Mooi River and connected streams in the vicin - ity of Potchefstroom, South Africa, was evaluated using the four-stage sequential extraction proce - dure. ... -
Metal speciation in the rivers around Potchefstroom based on seasonality
(Water Environment Federation, 2018)About 44 surface water samples were collected in the wet and dry seasons around mining areas near the city of Potchefstroom in South Africa, and physicochemical parameters were analyzed to assess the speciation of pollutants ... -
Metastability of the boron-vacancy complex in silicon: insights from hybrid functional calculations
(De Gruyter, 2018)Using four distinct configurations of the boron-vacancy (BV) complex in silicon, we investigate the experimentally observed defect metastability of the BV complex in silicon using the HSE06 hybrid functional within the ... -
A methodology to determine best-suited waiting-time periods for turbine start-up under fluctuating resources
(IEEE, 2019)— It is not uncommon for engineering process plants to comprise energy recovery. When power generation takes place under such circumstances, the nature of interlinked processes may result in fluctuating resource availability. ... -
A methodology to investigate the contribution of conduction and radiation heat transfer to the effective thermal conductivity of packed graphite pebble beds, including the wall effect
(Elsevier, 2017)The effective thermal conductivity represents the overall heat transfer characteristics of a packed bed of spheres and must be considered in the analysis and design of pebble bed gas-cooled reactors. During depressurized ... -
