Safety pharmacology of herbal medicines in South Africa
(Elsevier, 2019)The use of herbal medicine for treating various ailments has a deep history in South African traditional medicine. South Africa has a rich floral biodiversity which has been exploited for centuries mainly for day-to-day ... -
Search for High-redshift Blazars with Fermi/LAT
(Sissa Medialab, 2019)High-redshift blazars (z ≥ 2.5) are one of the most powerful classes of γ-ray sources in the Universe. These objects possess the highest jet powers and luminosities and have black-hole masses often in excess of 109 solar ... -
A search for optical counterparts of the complex Vela X system
(South African Institute of Physics, 2015)The pulsar wind nebula (PWN) associated with the Vela pulsar is a bright source in the radio, X-ray and gamma-ray bands, but not in the optical. This source is very near, lying at a distance of 290 pc, as inferred from ... -
Search for pulsed VHE gamma-ray emission from young pulsars with H.E.S.S.
(ICRC, 2008)We present the results of a search for pulsed very-high-energy (VHE) gamma-ray emission from young pulsars using data taken with the H.E.S.S. imaging atmospheric Cherenkov telescope system. Data on eleven pulsars, selected ... -
Securing number plates based on digital signatures and RFID
(IEEE, 2013)The automated detection of vehicles forms an important part of Intelligent Transportation Systems. The vehicle number plate is the primary token used for the identification of the vehicle; the number plates industry is ... -
Selective adsorption of heavy and light metals by natural zeolites
(PSRC, 2014)Recent studies have shown that zeolite can be applied through an ion-exchange process to remove metals from solutions. In this paper the potential of two zeolites to perform as sorbents for treatment of multi-metal system ... -
The selective targeting of cancer cells by using Pheroid® as a drug delivery system
(Elsevier, 2019)Pheroid® is a drug delivery system with possible use in the treatment of chronic diseases such as cancer and that enhances the efficacy of the treatment of chronic diseases [1]. Current cancer treatment is non-selective, ... -
Self Reported Vulnerability to Food Insecurity in a South African Low Income Neigbourhood
(World Business Institute, 2013)Food security is defined as a state in which all people in a household at all times have both physical and economic access to sufficient food to meet their dietary needs for a productive and healthy life. Household food ... -
Self-reported physical activity is not a valid method for measuring physical activity in 15 year old South African boys and girls
(Human Kinetics, 2018)Valid instruments for the assessment of physical activity remains a challenge in field studies. This study determine the level of agreement between objectively measured physical activity by ActiHeart® and the ... -
Semantic-driven E-government: a case study of formal representation of government domain ontology
(IEEE, 2011)Semantic Web technologies are increasingly being adopted in egovernment to describe and specify e-government services, aiming at their semantic integration and interoperability. However, current research does not ... -
The semi-automated creation of stratified speech corpora
(Pattern recognition association of South Africa (PRASA), 2013)Smartphones provide an efficient means for the collection of speech data; however, the quality of the corpora created in this fashion is not predictable. We describe an approach that allows us to post-process and rank ... -
Sensitivity of static energy meter reading errors to changes in non-sinusoidal load conditions
(IEEE, 2019)Previous studies regarding static energy meter errors under non-sinusoidal load conditions have shown that these meters can produce erroneous readings. This paper describes an investigation done using loads consisting ... -
Separation of lignin from industrial prehydrolysis liquor using a solid acid catalyst
(ETA-Florence Renewable Energies, 2019)The concept of a biorefinery has been introduced in the pulp and paper industry in order to improve the industry’s profitability and competitiveness by generating new revenues from new products. Prehydrolysis liquor (PHL) ... -
Series-parallel approach to on-line observer based neural control of a helicopter system
(Elsevier, 2014)This paper is concerned with the control of an under-actuated, uncertain, delayed non-linear system through the implementation of arti cial neural networks(ANNs). The aim is the development of a series-parallel training ... -
Short-term variation in the galactic cosmic ray intensity measured with the PAMELA experiment
(PoS, 2017)New results on the galactic cosmic ray (GCR) short-term intensity variation associated with Forbush decrease and co-rotating interaction regions (CIRs) measured by the PAMELA instrument between November 2006 and March ... -
Simplified performance monitoring of energy systems
(IEEE, 2014)Large energy consumers face mounting pressure due to recent energy cost increases, as well as regulatory requirements and limitations. Therefore, energy performance monitoring is an essential component of many modern ... -
Simulating operational improvements on mine compressed air systems
(Univ Stellenbosch, 2018)Compressed air systems are one of the most significant energy users on mines, with a contribution of about 20 per cent to the total electrical energy consumption on a mine. Research has shown that these compressed air ... -
A simulation approach to reconciling customs and trade risk associated with cross-border freight movements
(Stellenbosch Univ., 2016)Suider-Afrika is krities afhanklik van verhoogde uitvoer om ekonomiese groei te bevorder. Logistieke tekortkominge beperk uitvoer, en oorgrens vertragings is ’n sleutelfaktor wat koste verhoog en onsekerheid ...
