Activity-based risk management for the acquisition of electronic mine safety equipment
(SAIMM, 2017)A new approach is proposed to perform relativistic comparisons between alternative operational risk management solutions by taking into account the impact of each operational activity on overall system performance. ... -
Actors, observers, and the estimation of task duration
(Taylor & Francis, 2013)People are often wrong in estimating both how long tasks have taken in the past and how long they will take in the future. Bias could be due to factors such as task involvement, an individual’s engagement or motivation ... -
Acute and chronic effects of acidic pH on four subtropical frog species
(Water Research Commission, 2016)Acidic precipitation is implicated as a possible cause of global amphibian decline. Even protected areas such as Kruger National Park receive acid rain which may lead to possible negative effects on the park’s natural ... -
Acute cardiometabolic responses facilitating a state of chronic hyperglycemia and renal impairment: the SABPA study
(Wolters Kluwer, 2014)"Background: Augmented α-adrenergic response patterns are associated with vascular risk in Africans. The aims of this study were 1) to assess ethnic differences between glucose and cardiovascular responses during acute ... -
Acute changes in haematocrit leading to polycythaemia in late-onset hypogonadism patients that receive testosterone replacement therapy: a South African study
(Taylor & Francis, 2019)Background: According to the literature, parenteral testosterone replacement therapy (TRT)-induced polycythaemia is associated with cardiovascular events. No or minimal data exist for the prevalence of TRT-induced ... -
Acute exposure to environmentally relevant lead levels induces oxidative stress and neurobehavioral alterations in larval zebrafish (Danio rerio)
(Elsevier, 2020)The ubiquitous contamination of environmental lead (Pb) remains a worldwide threat. Improper Pb mine waste disposal from an abandoned lead-zinc mine has recently unearthed widespread Pb poisoning in children in Kabwe Zambia. ... -
Acute toxicity of double-walled carbon nanotubes to three aquatic organisms
(Hindawi Publishing Corporation, 2015)This study investigated the toxicity of double walled carbon nanotubes (DWCNTs) to three aquatic organisms, namely, Pseudokirchneriella subcapitata, Daphnia pulex, and Poecilia reticulata under the influence of exposure ... -
Adam Smith's contribution to secularisation
(AOSIS, 2013)This article examined several crucial themes in Adam Smith’s philosophy with the purpose of highlighting and assessing his contribution to the secularisation of Western society. The article, written from the perspective ... -

Adaptation and latent structure of the Swahili version of Beck Depression Inventory-II in a low literacy population in the context of HIV
(Public Library Science, 2016)Objective:We set out to adapt the Beck Depression Inventory (BDI)-II in Kenya and examine its factorial structure. Methods:In the first phase we carried out in-depth interviews involving 29 adult members of the community ... -
Adaptation and preliminary validation evidences of the School Climate Questionnaire - Revised, Elementary and Middle School Version (SCS-MS)
(Rua Ramiro Barcelos, 2016)This study presents the procedures for adapting the School Climate Survey - Revised, Elementary and Middle School Version (SCS-MS) to the Brazilian context and demonstrates the first evidence of the validity of its use ... -
Adaptation behaviour of bacterial species and impact on the biodegradation of biodiesel-diesel
(Brazilian Society of Chemical Engineering, 2017)Two bacteria, namely Bacillus subtilis and Pseudomonas aeruginosa were exposed to different concentrations of diesel to increase their adaptation to the fossil fuel, and were used for the degradation of diesel-biodiesel ... -
Adaptation in an era of vanishing territory – the political economy of the impact of clime change versus total migration, status of statehood and refugees in Africa
(Business Perspectives, 2014)Mass migration as a way of adapting to climate change impact is not new. However, the total migration of a permanent population from a defined territory as a coping response to the impact of climate change is only emerging. ... -
Adaptation to damaging dance and repeated-sprint activity in women
(Wolters Kluwer, 2016)he repeated bout effect (RBE) refers to the prophylactic effect from damaging exercise after a single previous bout of exercise. There is a paucity of data examining the RBE in women, and investigations using exercise ... -
Adaptations in corticospinal excitability and inhibition are not spatially confined to the agonist muscle following strength training
(Springer, 2017)Purpose We used transcranial magnetic stimulation (TMS) to determine the corticospinal responses from an agonist and synergist muscle following strength training of the right elbow flexors. Methods Motor-evoked potentials ... -
Adapting mobile medical information search to low-resourced areas
(IST-Africa, 2013)Providing good medical care in low-resourced areas is a challenge faced by many low and middle income countries. Continuously improving mobile communication infrastructure in these areas is however providing the opportunity ... -
Adapting plant measurement data to improve hardware fault detection performance in pressurised water reactors
(Elsevier, 2012)With the fairly recent adoption of digital control and instrumentation systems in the nuclear industry a lot of research now focus on the development expert fault identification systems. The fault identification systems ... -
Adapting the Macaulay duration for defaultable and option-embedded bonds
(Faculty of Economic and Management Sciences, University of Pretoria., 2008)Most contemporary bonds have embedded options and all face the possibility of default. Both features introduce risk (the former market risk and the latter credit risk) by altering the quantity and timing of the promised ... -
Adapting the singular spectrum analysis trajectory matrix technique to identify multiple additive time-series outliers
(Bureau for Economic Research and the Graduate School of Business, University of Stellenbosch., 2015)Singular spectrum analysis is a powerful non-parametric time series method that unfolds an observed time series into a special structured matrix, called a trajectory matrix. The trajectory matrix has a Hankel structure, ...
