Race, power and me: my position as a History educator in relation to the position of learners
(The South African Society for History Teaching (SASHT) under the auspices of the School of Basic Sciences, Vaal Triangle Campus, North-West University, 2015)History, as outlined in the Curriculum and Assessment Policy Statements for GET and FET (CAPS) is both a journey of enquiry and an evidence-based construction of the past. It enables learners and teachers alike to ... -
Rachel : verse van Totius / met voorwoord van President Steijn
(Potchefstroom : Koomans, 1913)Dit kan gevra worde, waarom ik van mijn re'el afwijk om hier 'n woord van aanbeveling te skrijwe, want enige gedig van Totius het tog bij ons volk g'n aanbeveling nodig. Die rede is dat die skrijwer ons weer die diens het ... -
Radial variation in porosity in annular packed beds
(Elsevier, 2008)This paper describes the results of a study of the variation in the radial direction in the porosity of annular packed beds. A comparison is made between the predictions by a number of empirical correlations found in ... -
The Radial Variation of the Solar Wind Turbulence Spectra near the Kinetic Break Scale from Parker Solar Probe Measurements
(American Astronomical Society, 2023)In this study we examine the radial dependence of the inertial and dissipation range indices, as well as the spectral break separating the inertial and dissipation range in power density spectra of interplanetary magnetic ... -
Radiation and polarization signatures of the 3D multizone time-dependent hadronic blazar model
(IOP Publishing, 2016)We present a newly developed time-dependent three-dimensional multizone hadronic blazar emission model. By coupling a Fokker–Planck-based lepto-hadronic particle evolution code, 3DHad, with a polarization-dependent radiation ... -
Radiation dose and radionuclide inventory characterization following a hypothetical nuclear criticality accident at a uranium processing facility
(North-West University (South Africa), 2021)This study focused on a hypothetical nuclear criticality excursion in a Plutonium Uranium Reduction EXtraction (PUREX) processing facility for the recovery of non-irradiated enriched uranium, which are present in scrap ... -
Radiation from relativistic particles accelerated at shear layers in relativistic jets
(North-West University (South Africa), 2023)Relativistic jets, highly collimated and high-velocity outflows of particles and electromagnetic radiation, are a common phenomenon associated with various astrophysical objects including stellar-mass compact objects ... -
A radiation monitoring program in a South African gold mine
(North-West University, 2005)Legislation requires the regular monitoring of all employees exposed to radiation in their work environment. The monitoring of a-radiation, which is emitted by radon gas, was the primary concern of this study. Radon comes ... -
Radical business ethics: a critical and postmetaphysical manifesto
(Wiley-Blackwell, 2012)Business ethics, as it is understood and practised generally, lacks a component of radicality. As part of the contemporary ‘return to ethics’ it displays an undesirable conservatism and blocks off possibilities for systemic ... -
Radical land reform in South Africa - a comparative perspective?
(University of the Free State, 2017)A great deal of political rhetoric has been uttered regarding radical economic transformation that includes calls for more radical land reform proposals. This rhetoric is the source of political mobilisation in both the ... -
The radicalisation of a Swedish ecclesiastical critic of apartheid-Gunnar Helander
(Scriber Editorial Systems, 2011)From the 1950s through the 1980s, both the government of Sweden and various non-governmental agencies in that country stood at the forefront of the international campaign against apartheid. To a considerable extent, ... -
Radicalism in contemporary South African political thought, as exemplified in selected political party rhetoric (1994-2021)
(North-West University (South Africa), 2023)South Africa has been a democracy for nearly three decades. During the past 28 years, the Republic of South Africa has been the subject of a constant process of political, economic and social change, as it is increasingly ... -
Radikale postkolonialisme en die Suid-Afrikaanse universiteitswese
(Suid-Afrikaanse Akademie vir Wetenskap en Kuns, 2016)This article concerns the wave of student protests that swept across South African universities during 2015 and 2016. The phenomenon of student protest at universities is approached and analysed against the backdrop of ... -
Radio afterglows of very high-energy gamma-ray bursts 190829A and 180720B
(Oxford Univ Press, 2020)We present high-cadence multifrequency radio observations of the long gamma-ray burst (GRB) 190829A, which was detected at photon energies above 100 GeV by the High Energy Stereoscopic System (H.E.S.S.). Observations with ... -
A radio and near-infrared study of 6.7 GHz methanol maser sources
(North-West University, 2004)The 6.7 GHz 51 - 60 A+ methanol maser transition was discovered relatively recently, in 1991. The exact nature of these masers is not known to date, but it seems likely that they are closely associated with high mass stars ... -
Radio broadcasting and the quest for democratic participation on Motsweding FM
(North-West University (South Africa), 2021)The study seeks to explore the role played by Motsweding FM’s news and current affairs programmes-Boresetse and Tsele Le Tsele as an avenue for citizen participation in the democratisation process. It interrogates more ... -
Radio frequency interference detection using machine learning
(IEEE, 2016)Radio frequency interference (RFI) has plagued radio astronomy which potentially might be as bad or worse by the time the Square Kilometre Array (SKA) comes up. RFI can be either internal (generated by instruments) or ... -
Radio imaging of the very-high-energy y-ray emission region in the central engine of a radio galaxy
(Science AAAS, 2009)The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particles to energies exceeding 1012 electron ... -
Radio observations of the region around the pulsar wind nebula HESSJ1303-631 with ATCA
(EDP Sciences, 2017)Radio observations of the region surrounding PSR J1301−6305 at 5.5 GHz and 7.5 GHz were conducted with ATCA on September 5, 2013. The observations were dedicated to the search of the radio counterpart of the evolved pulsar ...
