The detailed nature of active central cluster galaxies
(South African Institute of Physics, 2014)We present detailed IFU observations of the central few kiloparsecs of the ionised nebulae surrounding four active central cluster galaxies in cooling flow clusters. All four galaxies have Hα filaments, and existing data ... -
Determination and statistical evaluation of the effect of minerals and mineral associations in specific dense medium fractions on ash fusion temperature
(North-West University, 2005)During Sasol-Lurgi Fixed Bed Dry Bottom coal gasification, the mineral matter in coal undergoes various transformations. Heat induced transformation due to low ash fusion temperatures leads to agglomeration of the ash ... -
Determination of the therapeutic efficacy of a novel Pheroid® formulation in a rodent tuberculosis model
(Elsevier, 2019)Resistance against the current TB treatment regimens is spreading. A combination of the current TB regime with a novel drug delivery system, might lead to reduced resistance, shorter treatment durations and increased ... -
Developing a framework for assessing the influence of public service motivation on core work evaluation and counterproductive work behaviour
(IBC, 2022)The outcomes of low levels of public service motivation are low job satisfaction, organisational commitment, engagement and high levels of counterproductive work behaviour. This study’s primary aim was to ... -
Developing a dynamic control system for mine compressed air networks
(IEEE, 2014)Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed via compressed air ring networks where multiple shafts are supplied with compressed ... -
Developing multivariate models to predict abnormal stock returns - using cross-sectional differences to identify stocks with above average return expectations
(SCITEPRESS (Science and Technology Publications, Lda.), 2010)This paper describes the development of multivariate models used to identify stocks with above average return expectations. While most other research involving the development of stock return models involves time-series ... -
Developing transformational nutrition leaders in Africa
(Karger, 2017)Most African countries are burdened by undernutrition and all indications are that we are set to be particularly hard-hit by the growing burden of overnutrition. Despite significant investments, progress to ... -
Development and implementation of an advanced mobile data collection system
(SAIIE, 2016)This paper describes the development and implementation of a generic data collection tool. The Mobile Information Collection and Verification System (MICAVS) provides users with a generic platform to create application ... -
Development of a batch process to produce ethylated fatty acid esters
(Elsevier, 2019)Pharmaceutical excipients account for the majority of the volume of administered drugs [1]. The problem with the manufacture of pharmaceutical excipients is that they were considered to be inert support material with ... -
Development of a controller for fuel cell and supercapacitor application
(CATSA (Catalysis Society of South Africa), 2014)The growing demand for energy in the world causes a lot of pressure to the environment and the resources used to supply the energy. To ensure a continuous, more reliable and environmentally friendly energy supply system ... -
Development of a model for road transport fuel management
(SAIIE, 2016)Road transport is responsible for 76% of cargo movement in South Africa; at the same time transport cost in Sub-Sahara Africa forms a much higher fraction of the total cost of landed goods compared to the rest of the world. ... -
Development of a predictive pole-slip protection function for synchronous generators
(IEEE, 2015)Predictive pole-slip protection is not implemented in commercially available protection relays, since complex modeling of the network and generator is required to do such predictive detection. All pole-slip protection ... -
Development of a quadcopter for power line inspection
(2014)The inspection of transmission lines is to be done annually. It is proposed that a quadcopter is used to do the inspection of these transmission lines. The modelling of the quadcopter was done by studying its physical ... -
Development of an LC-MS/MS method for the quantification of goserelin from Pheroid® formulation
(Elsevier, 2019)The oral route is for many reasons the most common route of drug administration, however, due to gastrointestinal (GI) tract enzymatic stability issues, peptide drugs are administered parenterally. Goserelin is an ... -
Development of an online reputation monitor by using existing components
(SATNAC, 2014)Customer opinion about companies are very important and companies often get customer feedback via surveys or other official methods. Some customers prefer to voice their opinion on the internet where they take comfort ... -
Diagnosing relativistic particle acceleration in AGN jets
(AIP, 2017)Mildly relativistic, oblique shocks are generally considered to be among the most plausible sites of relativistic particle acceleration and the subsequent production of strongly variable, polarized multi-wavelength emission ... -
A digital signature issuing and verification system for auto identification tokens
(IEEE, 2012)The design of a Digital Signature Issuing and Verification System for Auto Identification Tokens is discussed. A system is proposed that is concerned with proving the validity of physical objects containing digital information ... -
Digital video shot boundary detector investigation
(SATNAC, 2014)Many algorithms have been proposed and evaluated for the detection of shot boundaries in digital video. Although these techniques have been verified, there remains a lack of standardised data to classify which techniques are ... -
Direct liquefaction of 2 South African bituminous coal fines and their beneficiated float fractions
(EARET, 2018)The direct liquefaction of South African coal fines and their density separated (float) fractions were carried out under moderate conditions in a laboratory autoclave. The liquefaction temperature ranged between 380 and ... -
Direct metal laser sintering, using conformal cooling, for high volume production tooling
(Univ Stellenbosch, 2017)Existing techniques to manufacture conventional tool steel inserts for the plastic injection moulding process are expensive and time-consuming. Complex mould inserts, difficult to manufacture with conventional processes, ...
