Evolution of faint radio sources in the VIDEO-XMM3 field
(OUP, 2013)It has been speculated that low luminosity radio-loud AGN have the potential to serve as an important source of AGN feedback, and may be responsible for suppressing star-formation activity in massive elliptical galaxies ... -
Evolution of star formation in the UKIDSS ultra deep survey field - I. Luminosity functions and cosmic star formation rate out of z = 1.6
(OUP, 2013)We present new results on the cosmic star formation history in the SXDS-UDS field out to z = 1.6. We compile narrow-band data from the Subaru Telescope and the Visible and Infrared Survey Telescope for Astronomy (VISTA) ... -
Evolution of the chemical composition of Sn thin films heated during x-ray photoelectron spectroscopy
(2019)High-vacuum XPS have been used to analyse the surface modification of a 3 nm-thick Sn thin film on Si (100) before and after annealing up to 450 °C. Increasing the XPS stage temperature led to a reduction in the amount of ... -
The Evolution of the concept of 'unfair discrimination' in South African Labour Law
(Juta Law, 2006)Introduction:This article examines the meaning and scope of the prohibition of unfair discrimination against employees contained in s 6 of the Employment Equity Act in the light of the development of the concept of 'unfair ... -
The evolution of the low-frequency radio AGN population to z 1.5 in the ELAIS N1 field
(Advance Access publication, 2020-11-13)We study the cosmic evolution of radio sources out to z 1.5 using a GMRT 610 MHz survey covering ∼1.86 deg2 of the ELAIS N1 field with a minimum/median rms noise 7.1/19.5 μJy beam−1 and an angular resolution of 6 arcsec. ... -
The evolution of the low-frequency radio AGN population to z 1.5 in the ELAIS N1 field
(Oxford University Press, 2021)We study the cosmic evolution of radio sources out to z ≃ 1.5 using a GMRT 610 MHz survey covering ∼1.86 deg2 of the ELAIS N1 field with a minimum/median rms noise 7.1/19.5 μJy beam−1 and an angular resolution of 6 arcsec. ... -
The evolution of the nosology of osteogenesis imperfecta
(Wiley-Blackwell, 2021)Osteogenesis imperfecta (OI) is a relatively common genetic skeletal disorder with an estimated frequency of 1 in 20 000 worldwide. The manifestations are diverse and although individually rare, the several different forms ... -
Evolutionary history of the Corallinales (Corallinophycidae, Rhodophyta) inferred from nuclear, plastidial and mitochondrial genomes
(Elsevier, 2011)Systematics of the red algal order Corallinales has a long and convoluted history. In the present study, molecular approaches were used to assess the phylogenetic relationships based on the analyses of two datasets: a large ... -
The evolving role of science in society
(José Frantz, 2020)The world is experiencing a traumatic change brought about by the Covid-19 pandemic. It is traumatic because it is sudden and affects everyone around the globe at once. Nothing like this has ever happened so rapidly before, ... -
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
(American Association for the Advancement of Science, 2022)Investment in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing in Africa over the past year has led to a major increase in the number of sequences that have been generated and used to track the ... -
Evolving statutory derivative action principles in South Africa: The good faith criterion and other legal grounds
(Cambridge University Press, 2021)The recent Supreme Court of Appeal (SCA) judgment in Lazarus Mbethe v United Manganese of Kalahari raises jurisprudential questions regarding statutory derivative actions in South Africa. For example, the SCA did not ... -
Ex-prisoners' views on imprisonment and re-entry
(Civil Society Prison Reform Initiative, 2009)This research project gathered information from ex-prisoners about their experiences during and after imprisonment. Knowing what prison system users think and say about the system is important because they are ultimately ... -
Ex-prisoners' views on imprisonment and re-entry
(Community Law Centre, University of the Western Cape, 2009)In the past 15 years much research has been conducted on the prison system in South Africa focusing on governance, law reform and human rights. It is, however, of particular concern that the voices of prisoners and ... -
Ex-situ electrochemical characterization of iro2 synthesized by a modified Adams fusion method for the oxygen evolution reaction
(MDPI, 2019)The development of highly stable and active electrocatalysts for the oxygen evolution reaction (OER) has attracted significant research interest. IrO2 is known to show good stability during the OER however it is not known ... -
Examination of maternal gingival crevicular fluid for the presence of selected periodontopathogens implicated in the pre-term delivery of low birthweight infants
(Landes Bioscience, 2010)Background: Reports show that more than 20 million infants world-wide are born prematurely with 95% of all pre-term births occurring in developing countries. Oral colonization of Gram-negative anaerobes has been implicated ... -
An examination of the psychometric properties and dimensionality of the Aggression-Problem Behavior Frequency Scale in a sample of Black South African adolescents
(Sage Journals, 2019)Advancing research into aggressive behaviour in South Africa necessitates a range of suitable measuring instruments. The Aggression-Problem Behavior Frequency Scale is one such instrument that has been extensively used in ... -
Examining inequality of opportunity in the use of maternal and reproductive health interventions in Sierra Leone
(Oxford University Press, 2020)Poor countries, such as Sierra Leone, often have poor health outcomes, whereby the majority of the population cannot access lifesaving health services. Access to, and use of, maternal and reproductive health services is ... -
Examining livelihoods and reconsidering rural development in the former homelands of South Africa
(Institute for Poverty, Land and Agrarian Studies, University of the Western Cape, 2017)Persistent poverty and under-development in South Africa’s former homeland communal areas have been little changed by post-apartheid ‘rural development’ policy. Rural development policy has often been characterised by ... -
