Fundamental physics with the square kilometre array
(Cambridge University Press, 2020)The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity and survey speed than any current radio ... -
Fundamentals of anti-bribery and anti-corruption compliance in South Africa
(University of Western Cape, 2019)Corruption is endemic in jurisdictions throughout the world. The financial and reputational risks that follow incidents of corrupt activity within an organisation are considerable. Often they can be quite severe. The ... -
Funding as a crisis for mature women students: Agency, barriers and widening participation
(University of the Western Cape, 2022)Drawing on a research investigation into the learning pathways of mature women, this chapter highlights funding as a crisis. Mature women students face barriers to access, participation and success in higher education. ... -
Fungal‑derived compounds and mycogenic nanoparticles with antimycobacterial activity: a review
(Springer, 2022)Tuberculosis (TB) is a persistent lung infection caused by Mycobacterium tuberculosis. The disease is characterized by high mortality rates of over 1 million per year. Unfortunately, the potency and efectiveness of currently ... -
Further evidence for periodontal disease as a risk indicator for adverse pregnancy outcomes
(Elsevier, 2017)Although there is increasing evidence to suggest an association between periodontal disease and adverse pregnancy outcomes, the issue remains controversial. Study objective: This study tested the hypothesis that ... -
Further from the people – bipartisan ‘nationalisation’ thwarting the electoral system
(SUN Press, 2012)This chapter argues that local government elections offer a unique opportunity in South Africa’s political system for voters to practice forms of democracy that are more local, plural and accountable in character than at ... -
Further observations of Hipparcos red stars and standards for UBV(RI)C photometry
(Oxford University Press, 2007)We present homogeneous and standardized UBV(RI)C JHK photometry for over 100 M stars selected from an earlier paper on the basis of apparent photometric constancy. L photometry has been obtained for stars brighter than ... -
Fusion-assisted hydrothermal synthesis and post-synthesis modification of mesoporous hydroxy sodalite zeolite prepared from waste coal fly ash for biodiesel production
(MDPI, 2022)Increases in biodiesel prices remains a challenge, mainly due to the high cost of conventional oil feedstocks used during biodiesel production and the challenges associated with using homogeneous catalysts in the process. ... -
The future of African customary law
(Elsevier, 2012)It s intended to promote discussion and understanding of customary law and to explore its continued relevance in sub-Saharan Africa…[It] considers the characteristics of customary law and efforts to ascertain and codify ... -
Future-making and scalar politics in a resource frontier: Energy projects in northern Kenya
(Institute for Poverty Land and Agrarian Studies (PLAAS), 2022-01-28)This contribution explores conflicts in the context of energy-related investments and infrastructure projects in Kenya’s arid and semiarid north. Over the past decade or so this historically marginalised region has turned ... -
Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects
(EDP Sciences, 2017)CONTEXT: The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are ... -
Gaia21bty: An exor light curve exhibiting a fuor spectrum
(Oxford University Press, 2023)Gaia21bty, a pre-main-sequence star that previously had shown aperiodic dips in its light curve, underwent a considerable ∆G ≈ 2.9 mag brightening that occurred over a few months between 2020 October and 2021 February. The ... -
The Galactic halo pulsar population
(Oxford University Press, 2018)Most population studies of pulsars have hitherto focused on the disc of the Galaxy, the Galactic centre, globular clusters, and nearby galaxies. It is expected that pulsars, by virtue of their natal kicks, are also to ... -
Galations 2:15-21 and the Belhar Confession (1986) in dialogue
(SUN, 2013)This article brings Gal 2: 15-21 into dialogue with the Confession of Belhar (1986). It starts off with the issue of the formation of confessions in Early Christianity and asks whether there could be a confession basic ... -
Galaxy and Mass Assembly (GAMA): A WISE Study of the Activity of Emission-line Systems in G23
(2020)We present a detailed study of emission-line systems in the GAMA G23 region, making use of WISE photometry that includes carefully measured resolved sources. After applying several cuts to the initial catalogue of ∼41,000 ... -
Galaxy And Mass Assembly (GAMA): Defining passive galaxy samples and searching for the UV upturn
(Oxford University Press, 2019)We use data from the GAMA and GALEX surveys to demonstrate that the UV upturn, an unexpected excess of ultraviolet flux from a hot stellar component, seen in the spectra of many early-type galaxies, arises from processes ... -
Galaxy and Mass Assembly (GAMA): Demonstrating the power of WISE in the study of Galaxy Groups to z < 0.1
(IOP Publishing, 2020)Combining high-fidelity group characterisation from the Galaxy and Mass Assembly (GAMA) survey and source-tailored z < 0.1 photometry from the WISE survey, we present a comprehensive study of the properties of ungrouped ... -
Galaxy and Mass Assembly (GAMA): Mid-infrared properties as tracers of galaxy environment
(EDP Sciences, 2023)We investigate how different mid-infrared (mid-IR) properties of galaxies are correlated with the environment in which the galaxies are located. For this purpose, we first study the dependence of galaxy clustering on the ... -
Galaxy And Mass Assembly (GAMA): Resolving the role of environment in galaxy evolution
(Oxford University Press, 2013)We present observations of 18 galaxies from the Galaxy And Mass Assembly (GAMA) survey made with the SPIRAL optical integral field unit (IFU) on the Anglo- Australian Telescope. The galaxies are selected to ... -
