X-ray and gamma-ray polarization in leptonic and hadronic jet models of blazars
(IOP Science, 2013)We present a theoretical analysis of the expected X-ray and γ-ray polarization signatures resulting from synchrotron self-Compton emission in leptonic models compared to the polarization signatures from proton synchrotron ... -
X-ray and gamma-ray variability of NGC 1275
(MDPI, 2020)Gamma-ray emission from the bright radio source 3C 84, associated with the Perseus cluster, is ascribed to the radio galaxy NGC 1275 residing at the centre of the cluster. Study of the correlated X-ray/gamma-ray emission ... -
X-ray diffraction parameters and reaction rate modeling for gasification and combustion of chars derived from inertinite-rich coals
(Elsevier, 2013)An investigation was undertaken to determine the effect of carbon structural properties on the reactivity of chars derived from inertinite-rich coal. The structures of chars were characterized by X-ray diffraction and ... -
X-ray polarimetry with the Polarization Spectroscopic Telescope Array (PolSTAR)
(Elsevier, 2016)This paper describes the Polarization Spectroscopic Telescope Array (PolSTAR), a mission proposed to NASA’s 2014 Small Explorer (SMEX) announcement of opportunity. PolSTAR measures the linear polarization of 3–50 keV ... -

Xenobiotic/medium chain fatty acid: CoA ligase - a critical review on its role in fatty acid metabolism and the detoxification of benzoic acid and aspirin
(Taylor & Francis, 2016)Introduction: Activation of fatty acids by the acyl-CoA synthetases (ACSs) is the vital first step in fatty acid metabolism. The enzymatic and physiological characterization of the human xenobiotic/medium chain fatty acid: ... -

Xenon-induced axial power oscillations in the 400 MW pebble bed modular reactor
(North-West University, 2007)This study evaluates the stability of the 400 MW Pebble Bed Modular Reactor (PBMR) core design with respect to axial xenon-induced power oscillations. Since the two-dimensional capabilities of the reactor dynamics code ... -
Xenophobic attacks on foreign shop owners and street vendors in Louis Trichardt Central Business District, Limpopo Province
(2015)Xenophobic attacks in South Africa in 2008 and 2015 sent shockwaves through the country and the world. In these events, around 70 people were killed while thousands were displaced; and, property and products of street ... -
Xenophobic societal attitudes in a "new" South Africanism: Governance of public perceptions, national identities and citizenship
(2015)This article argues that xenophobia is not a natural state of being for any society; instead, it is a product of socialisation which becomes excessive with violent abuses of the outgroup immigrants where such conduct is ... -
Xenophobic violence and criminality in the KwaZulu-Natal townships
(AOSIS, 2019)This study’s focus on the xenophobic violence in South Africa is topical, mostly concentrating on the economic competition between foreign nationals and local people as a root cause. Whilst the South African government’s ... -
Xenopus laevis as UberXL for nematodes
(Taylor & Francis, 2020)The effect of invasive species on local parasite dynamics is often overlooked. The African Clawed Frog Xenopus laevis (Daudin, 1802) (Anura: Pipidae) is a global invader, with established populations on four continents and ... -
Xenopus laevis oösiete as translasiesisteem vir reovirus-mRNA
(North-West University (South Africa), 1978)Several methods of approximation can be applied in the study of the translation process. In this dissertation a micro injection of Xenopus laevis oocytes was used in conjunction with reovirus mRNA as model in the study ... -
The y-ray spectrum of the core of Centaurus A as observed with H.E.S.S. and Fermi-LAT
(EDP Sciences, 2018)Centaurus A (Cen A) is the nearest radio galaxy discovered as a very-high-energy (VHE; 100 GeV–100 TeV) γ-ray source by the High Energy Stereoscopic System (H.E.S.S.). It is a faint VHE γ-ray emitter, though its VHE flux ... -
Yahweh’s ‘lord’ and unrestrained evil: an Exegesis of Psalm 110
(AOSIS, 2015)This article consists of an exegetical investigation of Psalm 110 and assumes that the psalms function in one sense as prayers, which can be prayed authentically by modern worshippers. Consequently, the specific images of ... -
The year of jubilee: a hermeneutic for social and moral transformation in South Africa
(AOSIS, 2011)This article aims to show that the Old Testament concept of the year of jubilee is neither an anachronistic, nor a peripheral de- tail of Scripture. It is an integral part of it and indeed one her- meneutical tool for ... -
Yeats's manuscripts and authorial intention.
(Taylor & Francis, 2014)The undermining of authorial intention through intertextuality and its consequent implications can sometimes lead to false assumptions about, not simply the meaning of texts, but the strategies used by authors in conveying ... -
Yeats, Vendler, and Byzantium
(Edinburgh University Press, 2014)Helen Vendler, in her magisterial Our Secret Discipline: Yeats and Lyric Form (2007), provides us with the tools with which to register the traditional formal elements of poetry, and she does so for the most part with her ... -
