Prelimanary application of a new Bolus Insulin model for Type 1 Diabetes
(Mary Ann Liebert, 2011)Previous work derived a theoretically rigorous bolus insulin model. It was shown that the new model predicts insulin response of subjects without diabetes substantially better than the carbohydrate counting method (CHOcm). ... -
Preliminary economic evaluation of thorium based fuels in PWRs
(Taylor & Francis, 2014)Many studies have proven that thorium-based fuel cycles are more expensive than current uranium fuel cycles, which is confirmed in this paper as well. This research, however, goes beyond the conventional nuclear ... -
Preparation and characterization of gum karaya hydrogel nanocomposite flocculant for metal ions removal from mine effluents
(Springer, 2016)This research paper reports the removal of heavy metal ions from mine effluents using the gum karaya (GK)-grafted poly(acrylamide-co-acrylic acid) incorporated iron oxide magnetic nanoparticles (Fe3O4 MNPs) hydrogel ... -
The preparation of activated carbon from South African coal
(SAIMM, 2012)Activated carbons used in the precious metals extraction industry are characterized by large internal surface areas and a great affinity for metal ions. The purpose of this research is to prepare activated carbon from ... -
Preparation of anodized aluminium oxide at high temperatures using low purity aluminium (Al6082)
(Elsevier, 2019)A rapid two-step anodization process was developed to prepare semi-ordered nanoporous anodized aluminium oxide (AAO) layers using an inexpensive aluminium (Al) alloy, Al6082 (97.53% Al) as the Al source material. Al anodizing ... -
Preparation of biochar from sunflower husks (Poster)
(ETA-Florence Renewable Energies, 2014) -
Preparation of biochars for co-gasification from sweet sorghum bagasse
(ETA-Florence Renewable Energies, 2015)Biochar is a solid product obtained through torrefaction, liquefaction or pyrolysis of organic material. It can be used for soil amendment, activated carbon for sequestration, or as bio-coal for gasification or co-gasification. ... -
Preparation of polyurethane from lignin and crude glycerol
(ETA-Florence Renewable Energies, 2015)Polyurethane foam (PUF) was prepared by a novel approach, using a renewable polyol derived from only biofuel production by-products, lignin and crude glycerol. This could potentially be a high value bio-refinery application ... -
Pressure-drop predictions in a fixed-bed coal gasifier
(Elsevier science, 2011)In the Sasol Synfuels plant in Secunda, Sasol-Lurgi fixed-bed dry-bottom gasifiers are used for the conversion of low-grade bituminous coals to synthesis gas (syngas). The gasifiers are fed with lump coal having a particle ... -
Pretreatment of coal power plant ro retentate using AR Floc 100
(EARET, 2018)The water purification process at Eskom includes a reverse osmosis (RO) treatment plant. There are several limitations to this process depending on the water characteristics. The most common problems limiting the success ... -
Prevalence of dyslipidaemia among type 2 diabetes mellitus patients in the Western Cape, South Africa
(MDPI, 2020)Dyslipidaemia, an irregular aggregate of lipids in the blood is common in diabetes and cardiovascular disease sufferers. A cross-sectional study on the prevalence of dyslipidaemia was performed among type 2 diabetes mellitus ... -
Processing spoken lectures in resource-scarce environments
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2011)Initial work towards processing Afrikaans spoken lectures in a resource-scarce environment is presented. Two approaches to acoustic modeling for eventual alignment are compared: (a) using a well-trained target-language ... -
The product yield problem and the history and future of washability analysis

Production of bio-degradable polyurethane foam from sugarcane bagasse and biodiesel-derived crude glycerine
(ETA-Florence Renewable Energies, 2015)As the threat of the depletion of fossil based fuels becomes more of a reality, there is a need to find alternative carbon sources for the production of a wide range of chemicals, polymers and plastics. One plastic that ... -
Production of citric acid from the fermentation of pineapple waste by Aspergillus niger
(Bentham Open, 2019)Background: Citric acid, aside its uses as a cleaning agent, has varied applications in the chemical, pharmaceutical, and food industries. A biotechnological fermentation process is one of the easiest ways to satisfy the ... -
Production of ethanol from sweetstem sorghum and tropical sugar beet for a rural community
(ETA-Florence Renewable Energies, 2011)Rural communities in the North West Province of South Africa are among the poorest in the world with an average income of less than ZAR 8.75 (EU 0.875) per day. The South African government has committed itself to upliftment ... -
Production of value-added products from biodiesel derived crude glycerol
(ETA-Florence Renewable Energies, 2015)Crude glycerol, a by-product of biodiesel production which contain impurities such as methanol, triglycerides and catalysts, would represent a huge challenge to the environment if disposed. Thus the best opportunity is to ... -
Progress in the development of methods used for the abatement of microbial contaminants in ethanol fermentations: a review
(Springer, 2019)Biofuel research and development roadmap is currently underway in several countries and is expected to pave a way for the establishment of a viable renewable energy sector that can compete with petroleum-based fuels. Ethanol ...
