The adsorption of copper in a packed-bed of chitosan beads: Modeling, multiple adsorption and regeneration
(Elsevier, 2009)In this study, exoskeletons of Cape rock lobsters were used as raw material in the preparation of chitin that was successively deacetylated to chitosan flakes. The chitosan flakes were modified into chitosan beads and the ... -
Adsorption of metal ions from fine coal tailings dump waste water using bio-char
(EARET, 2018)Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ... -
Adsorption potential of bentonite and attapulgite clays applied for the desalination of sea water
(PSRC, 2014)A possible new process for the partial desalination of seawater is to use bentonite clay or attapulgite as an adsorbent. The ion exchange property of these clays, which is a result of the characteristic t-o-t layer ... -
The advanced and moderate-growth development paths for the viability and future growth of small wind energy systems
(Elsevier, 2020)The government of South Africa initiated the Integrated Resource Plan (IRP) 2010–2030 to redefine the country's energy portfolio and commitment to wind energy development. The document recommended more research in small ... -
Aeroelastic analysis of T-tails using an enhanced doublet lattice method
(American Institute of Aeronautics & Astronautics, 2011)The subsonic doublet lattice method is widely used to calculate unsteady air loads for aeroelastic analyses. Despite its widespread use and significant improvements in other aspects of the method, its application to the ... -
Air drying of fine coal in a fluidized bed
(SAIMM, 2015)The demand for energy has continued to rise worldwide in line with population growth. The majority of South Africa’s electricity is supplied by coal-fired power stations. The amount of fine coal (-2 mm) generated at coal ... -
Alcohol and the oculomotor neural circuit: system identification, a delay-based approach
(IEEE, 2015)A fair amount of research has been done on the modeling of the oculomotor system. Models of the oculomotor neural circuitry that include the effect of alcohol are less plentiful in literature. We investigated the ... -
Amaranth lignocellulose as feedstock for bioethanol production: effect of microwave-assisted alkaline pretreatment on reducing sugar yield
(ETA-Florence Renewable Energies, 2014)A new class of lignocellulose derived from amaranth (Amaranthus Cruentus) represents a potential feedstock for bioethanol production. The lignocellulose material can be pretreated to yield high monomeric sugar concentrations ... -
Ammonia gas sensing characteristics of V2O5 nanostructures: a combined experimental and ab initio density functional theory approach
(Elsevier, 2020)A combined experimental and density functional theory of α-V2O5 for ammonia gas sensing have been investigated. The material was synthesized from hydrated NH4VO3 in CVD at 400 °C in N2 atmosphere for different time (12 h ... -
Analysing co-articulation using frame-based feature trajectories
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2010)We investigate several approaches aimed at a more detailed understanding of co-articulation in spoken utterances. We find that the Euclidean difference between instantaneous frame-based feature values and the mean values ... -
Analysing the porous structure of packed beds of spheres using a semi-analytical approach
(Elsevier, 2019)In this paper methodologies are described for the analysis of the porous structure of cylindrical and annular packed beds consisting of spheres when the coordinates and sizes of the spheres are known. Methodologies to ... -
Analysing two control methods of shunt active filters for unbalanced load
(Nagpur: Yeshwantrao Chavan College of Engineering, 2014)A three-phase shunt active filter is used for current and/or voltage unbalance compensation. Two control schemes with two different theory, instantaneous power theory and Generalized Fryze are considered to compensate the ... -
Analysis of a 405 km transmission line with series compensation
(EE Publishers, 2012)This paper presents an investigative case study and energy efficiency analysis of the 405 km, 420 kV transmission line between Insukamini substation in Bulawayo in Zimbabwe and the Matimba thermal power station in South ... -
Analysis of metal-laden water via portable X-ray fluorescence spectrometry
(Elsevier, 2018)A rapid method for in-situ elemental composition analysis of metal-laden water would be indispensable for studying polluted water. Current analytical lab methods to determine water quality include flame atomic absorption ... -
Analysis of PM transverse-flux outer rotor machines with different configuration
(IEEE, 2017)This paper presents the electromagnetic analysis of two permanent magnet transverse-flux outer rotor machines with and without magnetic shunts. The research started with designing and analyzing a permanent magnet transverse-flux ... -
Analysis of reaction mixtures of perhydro-dibenzyltoluene using two-dimensional gas chromatography and single quadrupole gas chromatography
(Elsevier, 2018)Energy storage via liquid organic hydrogen carrier (LOHC) systems has gained significant attention in recent times. A dibenzyltoluene (DBT) based LOHC offers excellent properties which largely solve today's hydrogen storage ... -
Analysis of reference ranges of total serum protein in Namibia: clinical implications
(MDPI, 2020)A reference range is an essential part of clinical laboratory test interpretation and patient care. The levels of total serum protein (TSP) are measured in sera to assess nutritional, liver, and kidney disorders. This ... -
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ...
