Attitudes towards environmental issues: a case of Bophelong Township
(The Social Sciences Research Society (SOSRES), 2013)This paper examines the attitudes that the households of Bophelong Township have towards environmental issues in their area. Focus was placed on issues pertaining to air pollution and littering in the Township. The study ... -
Attitudes towards information privacy amongst black South African Generation Y Students: A study of loyalty cards
(Mediterranean Center of Social and Educational Research (MCSER), 2013)Aim: In this era of globalisation characterised with rapid spread and usage of Information Communication Technology (ICT) and the capacity to store personal information, the issue of information privacy is becoming an ... -
Augmented supraspinal fatigue following constant-load cycling in the heat
(Wiley, 2015)The development of central fatigue is prominent follow- ing exercise-induced hyperthermia, but the contribution of supraspinal fatigue is not well understood. Seven endurance-trained cyclists (mean ± SD peak O 2 uptake, 62.0 ... -
Authenticating the presence of a relativistic massive black hole binary in OJ 287 using its general relativity centenary flare: improved orbital parameters
(IOP Publishing, 2018)Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show that observations associated with the ... -
Autobin: a predictive approach towards automatic binning using data splitting
(SASA, 2018)The concept of binning is known by many names: discretisation, classing, grouping and quantisation. It entails the mapping of continuous or categorical data into discrete bins. Binning is an important pre-processing step ... -
Automated continuous air monitoring
(Elsevier, 2015)Anthropogenic and anthropogenically induced emissions (such as emissions due to land use change) of various gaseous and particulate atmospheric species have substantially increased since the onset of the industrial ... -
Automated fiber diameter and porosity measurement of fibrin clots in SEM images
(Biophysical Society, 2020)SEM images of fibrin meshes can provide profound insights into the microstructure of blood clots. This is significant because characteristics of clot microstructure, such as fiber diameter and clot porosity, may be altered ... -
Automatic alignment of audiobooks in Afrikaans
(Pattern recognition association of South Africa (PRASA), 2012)This paper reports on the automatic alignment of audiobooks in Afrikaans. An existing Afrikaans pronunciation dictionary and corpus of Afrikaans speech data are used to generate baseline acoustic models. The baseline system ... -
Automatic speech recognition for under-resourced languages: A survey
(Elsevier, 2014)Speech processing for under-resourced languages is an active field of research, which has experienced significant progress during the past decade. We propose, in this paper, a survey that focuses on automatic speech ... -

Automatic vs manual assessment of programming tasks
(ACM, 2017)Lecturers are struggling to keep up with their daily responsibilities because of an ever-increasing workload. Manual programming assessment processes are time-consuming, but a possible solution is to use the assistance of ... -
Automation of generalized additive neural networks for predictive data mining
(Taylor & Francis, 2011)For a new technology to make the step from experimental technology to mainstream technology, tools need to be created to facilitate the use of the developed technology in the envisaged application area. Generalized additive ... -
Automation of membrane based solvent extraction unit for Zr and Hf separation
(Elsevier, 2017)In recent years, research into metal ion solvent extraction using hollow fibre membranes has grown. Current studies generally use an analogue controlled experimental setup. Although the analogue system is sufficient for ... -
Avian interspecific differences in VKOR activity and inhibition: insights from amino acid sequence and mRNA expression ratio of VKORC1 and VKORC1L1
(Elsevier, 2020)Worldwide use of anticoagulant rodenticides (ARs) for rodents control has frequently led to secondary poisoning of non-target animals, especially raptors. In order to suggest some factors that may help considering the ... -
The awakening of BL Lacertae: observations by Fermi, Swift and the GASP-WEBT
(Oxford University Press, 2013)Since the launch of the Fermi satellite, BL Lacertae has been moderately active at γ-rays and optical frequencies until 2011 May, when the source started a series of strong flares. The exceptional optical sampling achieved ... -
Bacillus pumilus strain YSPMK11 as plant growth promoter and bicontrol agent against Sclerotinia sclerotiorum
(Springer, 2017)A study was executed in a direction to attenuate Sclerotinia stalk rot (SSR) disease through biocontrol agent and also to enhance crop productivity. Culture filtrate of bacterial strain YSPMK11 inhibited growth of Sclerotinia ... -
Bacillus-based bionematicides: development, modes of action and commercialisation
(Taylor & Francis, 2018)Agricultural crops are severely damaged by root-knot nematodes causing extensive financial losses globally. Historically, agrochemicals have been the preferred method to combat these pests; however, threats to humans and ... -
Bacterial community composition of an urban river in the North West Province, South Africa, in relation to physico-chemical water quality
(Springer, 2016)The aim of this study was to determine the impacts of anthropogenic disturbances on bacterial community composition in an urban river (Mooi River). Physico-chemical analysis, bacterial enumeration and 454-pyrosequencing ... -
Bacterial diversity and mycotoxin reduction during maize fermentation (steeping) for ogi production
(Frontiers Research Foundation, 2015)Bacterial diversity and community structure of two maize varieties (white and yellow) during fermentation/steeping for ogi production, and the influence of spontaneous fermentation on mycotoxin reduction in the gruel were ... -
Bacterial pathogens identified from houseflies in different human and animal settings : a systematic review and meta‐analysis.
(Elsevier, 2022)Housefly (Musca domestica) is an excellent candidate for the distribution of susceptible and resistant bacterial strains that potentially threaten public health. To date, there is a paucity of information on the global ...
