Actantial model of Judith, a key to unlocking its possible purpose: a greimassian contribution
(Old Testament Society of South Africa (OTSSA), 2015)The goal of this article is to investigate the possible purpose of the Greek apocryphal book of Judith. The investigation of the possible purpose of Judith has attracted the interest of many scholars and varying contributions ... -
Actinellopsis murphyi gen. et spec. nov.: a new small celled freshwater diatom (Bacillariophyta, Eunotiales) from Zambia
(Magnolia Press, 2014)In this paper we describe Actinellopsis murphyi gen. et spec. nov. a small heteropolar and dorsiventral diatom from a seep habitat in Zambia. This novel taxon has the chief distinguishing characteristic, along with its ... -
Action evolution for intelligent agents
(IEEE, 2005)This paper introduces an alternative method of reinforcement learning for intelligent agents. The aim with this method is to closer emulate the natural thought processes of problem solving. This paper only provides a ... -
Action research for the 21st century: exploring new educational pathways
(Unisa, 2014)Twenty years into democracy in South Africa, poverty and disease continue to limit the life prospects of the majority of people. Researchers in higher education have an opportunity, not to mention a moral obligation, to ... -
Activation gap generators in neural networks
(In Proc. South African Forum for Artificial Intelligence Research (FAIR2019), 2019-12)No framework exists that can explain and predict the generalisation ability of DNNs in general circumstances. In fact, this question has not been addressed for some of the least complicated of neural network architectures: ... -
Activation in the context of the unemployment insurance system in South Africa
(Juta, 2011)The main aim of labour market activation policies is to bring jobless people from unemployment or inactivity into work or, at the very least, to influence the employment prospects of the unemployed positively. Activation ... -
An active hybrid energy storage system utilising a fuzzy logic rule-based control strategy
(MDPI, 2020)The research presented in this paper documents the implementation of an active hybrid energy storage system that combined a battery pack and an ultracapacitor bank. The implemented hybrid energy storage system was used ... -
Active magnetic bearing condition monitoring
(Emerald, 2013)In this paper, condition monitoring of the internal parts of a radial active magnetic bearing (AMB) system is performed by means of Cepstrum analysis, Wigner-Ville Distributions (WVD) and enveloped Equi-Sampled Discrete ... -
Active surface area approximation in a lead-acid cell for optimal performance in renewable energy systems
(IFAC, 2014)In a renewable energy system, lead-acid batteries are required to last as long as possible whilst providing deep discharges and are usually charged in an intermittent manner. This type of operation is severely detrimental ... -
Activities of 11-azaartemisinin and N-sulfonyl derivatives against asexual and transmissible malaria parasites
(Wiley, 2017)Dihydroartemisinin (DHA), either used in its own right or as the active drug generated in vivo from the other artemisinins in current clinical use—artemether and artesunate—induces quiescence in ring-stage parasites of ... -
Activities of 11-azaartemisinin and N-sulfonyl derivatives against Neospora caninum and comparative cytotoxicities
(Wiley, 2017)Neosporosis caused by the apicomplexan parasite Neospora caninum is an economically important disease that induces abortion in dairy and beef cattle. There are no vaccines or drugs available on the market for control or ... -
Activity coefficients at infinite dilution of hydrocarbons in glycols: experimental data and thermodynamic modeling with the GCA-EoS
(Elsevier, 2017)The infinite dilution activity coefficients for 12 non-polar hydrocarbon solutes in the solvents, monoethylene and diethylene glycol, were measured using the gas-liquid chromatography technique. Pre-saturation of the carrier ... -
Activity preferences of 9- to 10-year-old girls and the relationship between object control skills and physical activity levels : the NW-Child Study
(Univ Stellenbosch, 2017)Early object control (OC) skills proficiency is reported to be related to long-term physical activity (PA). The percentage of participation in moderate- and high-intensity PAs and the relationship between PA levels and OC ... -
Activity-based costing in small manufacturing firms: South African study
(Clute Institute, 2013)This is an empirical investigation by means of a survey of the experiences and perceptions of activity-based costing (ABC), as an alternative to traditional costing, in small manufacturing firms in the Southern Gauteng ... -
Activity-based learning: a business management case study
(Academic journals, 2012)Many business management lecturers in higher education institutions conform to traditional teaching methods, such as lecturing, with the occasional questions-and-answers teaching method. This pedagogical approach often ... -
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 ...
