Applications of linear superposition principle to resonant solitons and complexitons
(Elsevier, 2017)We apply the linear superposition principle to Hirota bilinear equations and generalized bilinear equations. By extending the linear superposition principle to complex field, we construct complex exponential wave function ... -
Applications potential of structural path analysis in urban agriculture: a literature review
(Kamla-Raj Enterprises, 2014)Structural path analysis (SPA) is a specialized SAM technique in which transaction values and direction are loaded on to flow networks between market players in order to capture the size, direction and intensity of ... -
Applying a transdisciplinary mixed methods research design to explore sustainable diets in rural South Africa
(Sage, 2015)This article describes a conceptual framework for exploring sustainable diets, using a case study example of ongoing research in the Vaalharts region, a rural setting in South Africa. A qualitative research approach is ... -
Applying AFLPs in Aizoaceae: the delosperma herbeum complex as a case study

Applying lessons learnt from deficiencies in the Basel Accords to Solvency II
(Sabinet, 2013)Solvency II is the new European Union (EU) legislation that will review the capital adequacy regime for the insurance industry. Considerable progress has been made in the banking sector with the implementation of the Basel ... -
Applying Monte Carlo methods to model multi-wavelength emission of RMHD jet simulations.
(Sissa Medialab, 2019)Relativistic jets associated with active galactic nuclei (AGN) produce radiation over a large range of the electromagnetic spectrum. While relativistic magneto-hydrodynamic (RMHD) simulations have become a powerful tool ... -
Applying predictive analytics in identifying students at risk: a case study
(Stellenbosch Univ, 2016)In this article, a case study is presented of an institutional modelling project whereby the most appropriate learning algorithm for the prediction of students dropping out before or in the second year of study was identified ... -
Applying the science of learning to the learning of science: Newton’s second law of motion
(Taylor & Francis, 2018)Science teaching and learning require knowledge about how learning takes place (cognition) and how learners interact with their surroundings (affective and sociocultural factors). The study reported on focussed on learning ... -
Appraising coach performance: A qualitative analysis of coaches perceptions
(LAM Publications; AJOL; Sabinet, 2013)As a result of the proliferation of international competition, increased participation in sport, increased sponsorship, increased visibility of sport and greater levels spectatorship, the management of human resources in ... -
Appraising the value of independent EIA follow-up verifiers
(Elsevier, 2015)Independent Environmental Impact Assessment (EIA) follow-up verifiers such as monitoring agencies, checkers, supervisors and control officers are active on various construction sites across the world. There are, however, ... -
An approach towards the planning of green child-friendly spaces in South Africa
(Oxford Univ Press, 2018)The impact of green spaces in terms of sustainability and quality of life is well documented in recent literature. Such is the growing awareness of the importance and benefits of designing healthy, safe public spaces for ... -
Appropriate and non-medical use of methylphenidate by residence students at a South African tertiary institution
(LAM Publications, 2017)The purpose was to determine to what degree residence students from a tertiary academic institution use methylphenidate in both non-medical and appropr iate manners in the South African ... -
Aquatic invertebrate community structure of selected endorheic wetlands (pans) in South Africa
(Taylor & Francis, 2016)Shallow wetlands, such as pans, are not well studied in South Africa, even though they perform many important functions, such as providing an important food source for migratory birds and habitat to highly specialized ... -
Aqueous solubility of Cr(VI) compounds in ferrochrome bag filter dust and the implications thereof
(WRC, 2017)The production of ferrochrome (FeCr) is a reducing process. However, it is impossible to completely exclude oxygen from all of the high-temperature production process steps, which may lead to unintentional formation of ... -
Arbuscular mycorrhizal fungal community differentiation along a post-coal mining reclamation chronosequence in South Africa: a potential indicator of ecosystem recovery
(Elsevier, 2020)Arbuscular mycorrhizal (AM) fungi contribute to the restoration of soil ecological functions and processes during ecosystem development. Here, diversity and differentiation of AM fungi in rhizosphere soils and roots of the ... -
Are anomalous cosmic rays the main contribution to the low-energy galactic cosmic ray spectrum?
(IOP Publishing, 2008)While the high-energy part of the Galactic cosmic ray spectrum is well observed, its nature at energies below about 1 GeV nucleon-1 is still not known well. Recent in situ measurements made with the Voyager 1 spacecraft in ... -
Are current effectiveness criteria fit for purpose? Using a controversial strategic assessment as a test case
(Elsevier, 2018)The aim of this paper is to test the broader utility of the sustainability assessment effectiveness framework of Bond et al. (2015) by applying it to a controversial strategic assessment case study. The effectiveness ... -
