Evaluation of cottonseed oil as co-feedstock for the hydroprocessing of petroleum middle distillates for diesel fuel production
(ETA, 2016)Mandatory blending of biodiesel into petroleum diesel came to effect in 2015 in South Africa. The availability of biodiesel to implement this mandate however poses a challenge for local biodiesel producers and petroleum ... -
Evaluation of design and planning parameter impact by energy efficient measures through appliance-based modelling
(IEEE, 2017)In a rapidly evolving industry as a result of consumer self-generation and a drive to become more energy efficient, it is necessary to understand whether traditional network planning methods are sufficient. Electrical ... -
Evaluation of harmonic distortion from multiple renewable sources at a distribution substation
(IEEE, 2017)Harmonic emission assessment in a distribution network with existing background voltage harmonics is a challenge for Renewable Power Producers (RPP) aiming to achieve grid code compliance. Dynamic interaction of harmonic ... -
The evaluation of spent coffee grounds as feedstock for continuous hydrothermal liquefaction
(EARET, 2018)This study looks at converting a low-value waste in a continuous hydrothermal liquefaction reactor to a high-value biocrude and biochar product. The feedstock chosen for this study was spent coffee grounds (SCG) as spent ... -
Evaluation of system losses due to harmonics in medium voltage distribution networks
(IEEE, 2016)Power system harmonics are a known cause to failure, disoperation or premature aging of customer's equipment. It also causes additional losses in a distribution network that influence the planning and design of future ... -
Evaluation of the in vitro antimicrobial activity of a Pheroid®- entrapped plant extract against human pathogens
(Elsevier, 2019)This plant extract (PE) has proven activity against fungi affecting crops in South Africa. However, there is currently insufficient data on the activity of the PE against human pathogens. The general aim of this study ... -
Evaluation of the oral delivery of a peptide with Pheroid® technology
(Elsevier, 2019)Goserelin is a type of hormone therapy used in addition to standard adjuvant therapy. Currently, goserelin is only available as a slow releasing subcutaneous implant but this is an invasive and generally not well- tolerated ... -
Evaluation of the wideband compressive radio receiver for spectrum sensing
(IEEE, 2011)We present an empirical evaluation of the carrier detection method used in the Wideband Compressive Radio Receiver (WCRR), which is of particular interest for spectrum sensing in Cognitive Radio (CR) and Dynamic Spectrum ... -
Evaluation of waste-to-energy grate incineration power plant drivers and barriers for a small South African city: a swot analysis approach
(SAIIE, 2016)The global share of energy from waste is approximately 0.4% of global energy consumption. The average amount of municipal solid waste generated in South Africa is equivalent to 11 GWh wasted energy. This paper focuses on ... -
Evidence-informed decision making for nutrition: African experiences and way forward
(Cambridge Univ Press, 2017)Although substantial amount of nutrition research is conducted in Africa, the research agenda is mainly donor-driven. There is a clear need for a revised research agenda in Africa which is both driven by and responding to ... -
The exceptional VHE gamma-ray outburst of PKS 1510-089 in May 2016
(PoS, 2017)PKS 1510-089 (z=0.361) is one of only a handful of flat spectrum radio quasars that have been detected at very high energy (VHE, E > 100GeV) gamma rays. It is a very active source across the entire electromagnetic spectrum. ... -
Expanding industrial thinking by formalizing the industrial engineering identity for the knowledge era
(IEOM, 2017)To date, the formal identity of the Industrial Engineer remains vague. D ue to the broad knowledge base and application areas made available to Industrial Engineers, pinning down the commonality has ... -
EXPANSION STRATEGIES IN THE AGRO-PROCESSING SECTOR FOR SMALL-SCALE AGRO-PROCESSORS IN SOUTH AFRICA
(IBC, 2021)The study was aimed at developing strategies for expansion by small-scale agro-processors in South Africa. This article purports that post-colonial states are organizations that choose to develop ... -
The expected very-high-energy flux from a population of globular clusters
(SAIt, 2015)Given their old ages, globular clusters are expected to harbour many evolved stellar objects. Their high core densities enhance stellar encounter rates, also facilitating the formation of stellar end products. In particular, ... -
Experimental results of an asynchronous machine with thermoelectric cooling modules
(2012)It is estimated that globally around 40% of the electricity supplied to the industrial sector is consumed by electric motorised systems and for South Africa around 60% of the electricity supplied is consumed by asynchronous ... -
Experimental study on liquid hydrocarbon formation during pressurized underground coal gasification conditions
(2018)UCG is a gasification process used to produce synthesis gas from coal in situ (underground in the coal seam) by injecting air or oxygen, with or without steam, into coal seams and extracting the product gas via surface ... -
Experimentelle und theoretische Untersuchungen zum Rotorabsturz in Wälzlager
(2011)Um eine Auslegung von Fanglagern durchzuführen ist es notwendig, die Belastungen dieser in den zu erwartenden Abwurfszenarien zu kennen. Da so ein chaotischer Vorgang schwer analytisch berechnet werden kann, ist es ... -
Exploiting high-energy polarization in blazars
(Sissa Medialab, 2018)The spectral energy distributions (SEDs) and variability of astrophysical sources can be modeled in many different ways, in particular, the production of X-rays and γ-rays in the SEDs of blazars. High-energy polarimetry ... -
Exploration of biomarkers for subclinical atherosclerosis in an African population using a proteomics chip targeted at inflammation and cardiovascular disease
