Small business owner-managers' perceptions of entrepreneurship in the Emfuleni district
(University of Pretoria, 2008)The primary objective of this study was to analyse small business owner-managers' perceptions of entrepreneurship and their motives to start their businesses in the Emfuleni district in South Africa. A total of 307 useable ... -
Small but diverse: larval trematode communities in the small freshwater planorbids Gyraulus albus and Segmentina nitida (Gastropoda: Pulmonata) from the Ruhr River, Germany
(Springer, 2018)In contrast to the well-studied trematode fauna of lymnaeid snails, only little is known about the role of small planorbid snails as first intermediate hosts for trematodes in temperate freshwater systems. This study aims ... -
Small ideas for big impacts: multifunctionality in the rural village of Verkykerskop
(UOVS, 2018)Nijkamp affirms the Utopians’ claim of an open and flexible future, where development could imply surprising steps towards something better. Castells questions admonishingly whether planning approaches are changeable in a ... -
Small molecule fluorescent ligands as central nervous system imaging probes
(Bentham Science, 2013)The design, development and use of small molecule fluorescent ligands to directly or indirectly study receptors, enzymes and other targets in the central nervous system (CNS) have in the recent years become an intense area ... -
Small-amplitude supersolitons near supercritical plasma compositions
(Cambridge Univ Press, 2017)Supercritical plasma compositions in parameter space are considered for a general fluid model consisting of an arbitrary number of species. This is done by applying a Taylor series expansion of the Sagdeev potential about ... -
Smallholder farmer’s adoption intensity of genetically modified maize varieties in Thulamela municipality, Limpopo province, South Africa
(Business Perspectives, 2015)The issues embedded in the controversy surrounding genetically modified crops are varied and complex. Despite the benefits that come with cultivating these crops, adoption has been slow, especially by smallholder farmers. ... -
Smart whiteboard for interactive learning
(IEEE, 2018)The need for educators conveying information more interactively has increased as we are moving into a more technological era. A need for increasing the efficiency of lectures has become very important. This project addresses ... -
A smartphone-based ASR data collection tool for under-resourced languages
(Elsevier, 2014)Acoustic data collection for automatic speech recognition (ASR) purposes is a particularly challenging task when working with under-resourced languages, many of which are found in the developing world. We provide a brief ... -
SmartRoad: a new approach to law enforcement in dense traffic environments
(IEEE, 2015)Road transport law enforcement is facing new challenges against the background of increasingly congested traffic conditions. An ideal law enforcement system must enable authorities to detect, identify and act against illegal ... -
Smoke and clouds above the Southeast Atlantic: upcoming field campaigns probe absorbing aerosol’s impact on climate
(American Meteorological Society, 2016)From July through October, smoke from biomass-burning (BB) fires on the southern African subcontinent is transported westward through the free troposphere over one of the largest stratocumulus cloud decks on our planet ... -
Smoking and vascular dysfunction in Africans and caucasians from South Africa
(Clinics Cardive, 2011)Background: Smoking is an important modifiable risk factor for cardiovascular disease, with limited research having been done in Africans. We aimed to determine the association between smoking and measurements of vascular ... -
Smoking prevalence and attributable disease burden in 195 countries and territories, 1990–2015: a systematic analysis from the Global Burden of Disease Study 2015
(Elsevier, 2017)Background The scale-up of tobacco control, especially after the adoption of the Framework Convention for Tobacco Control, is a major public health success story. Nonetheless, smoking remains a leading risk for early death ... -
Smooth copula-based estimation of the conditional density function with a single covariate
(Elsevier, 2017)Some recent papers deal with smooth nonparametric estimators for copula functions and copula derivatives. These papers contain results on copula-based Bernstein estimators for conditional distribution functions and related ... -
Snapshots of student-teachers’ experiencies of DVDs in a learner support programme in a developing ODL context
(Taylor & FrancisUnisa Press, 2014)The School of Continuing Teacher Education (SCTE) in South Africa delivers an Advanced Certificate in Education (ACE) Learner Support Programme to Open Distance Learning (ODL) students in Namibia, a developing sub-Saharan ... -
SNR G39.2-0.3, an hadronic cosmic rays accelerator
(Oxford Univ Press, 2020)Recent results obtained with gamma-ray satellites have established supernova remnants as accelerators of GeV hadronic cosmic rays. In such processes, CRs accelerated in SNR shocks interact with particles from gas clouds ... -
SO2 - an indirect source of energy
(SAIMM, 2013)Global sulphur dioxide (SO ) emissions peaked around the mid- 1970s, after which they declined. However, with the growth of specifically China, emissions are on the rise again. In 2008, global anthropogenic SO emissions ... -
SO2 crossover flux of Nafion® and sFS-PBI membranes using a chronocoulometric (CC) monitoring technique
(Elsevier, 2012)A chronocoulometric electrochemical measuring technique was used to evaluate the gas flux and permeation properties of sulphuric acid dissolved SO2 across various polymeric membranes, using an in-house assembled permeation ... -
SO2 seasonal variation and assessment of Ozone Monitoring Instrument (OMI) measurements at Sharpeville (27.86°E; 26.68°S) a South African ground-based station
(Taylor & Francis, 2017)In this study, seasonal, inter-annual variations of sulphur dioxide (SO2) were analysed for Sharpeville, South Africa (27.86°E; 26.68°S) for the period 2007–2013. Sharpeville is a residential site located within a highly ... -
SO2 solubility in 50 wt % H2SO4 at elevated temperatures and pressures
