Correlation between the expectations of patients and their new complete removable dentures, constructed by undergraduate students
(South African Dental Association, 2018)Most edentulous patients have expectations regarding complete dentures which may impact on their levels of satisfaction. AIM: To determine whether their expectations influence the satisfaction of patients with new complete ... -
Correlative imaging and histopathology of a complicated sinonasal teratocarcinosarcoma
(SA Journal of Radiology, 2023)Sinonasal teratocarcinosarcoma (SNTCS) is a highly malignant and rare tumour characterised by a complex admixture of teratomatous and carcinosarcomatous components. In the head and neck area, it almost exclusively occurs ... -
Corrigendum: Immunological changes during space travel: A ground-based evaluation of the impact of neutron dose rate on plasma cytokine levels in human whole blood cultures
(Frontiers Media, 2021)A better understanding of the combined impact of different space stressors on human health is urgently warranted, considering the upcoming long-duration missions beyond lower Earth orbit. Therefore, a growing number of ... -
Corrigendum: Novel Coronavirus and regular physical activity involvement: Opinion
(AOSIS, 2021)The novel coronavirus (NCOVID-19) has quickly become a public health concern globally and needs urgent attention. While there is no current evidence of vaccines and specific drugs to prevent and treat the ailments emanating ... -
Corrigendum: Synthesis and cytotoxic activity of novel indole derivatives and their in silico screening on spike glycoprotein of sars-cov-2
(Frontiers Media, 2021)The authors Kaliappillai Vijayakumar, Magda H. Abdellattif, Mohd Shahbaaz were not included in the published article and the authors Daoud Ali, Saud Alarifi, and Amal Alotaibi were mistakenly included in the author list. ... -
Corrosion improvement of 304l stainless steel by zrsin and zrsi(N,o) mono-and double-layers prepared by reactive cathodic arc evaporation
(MDPI, 2021)Zr-based nitrides and oxynitrides were deposited by reactive cathodic arc evaporation in monolayer and double-layer structures with the aim of increasing the corrosion protection of 304L stainless steel (SS) in a biomedical ... -
Corrupting perceptions: The impact of the united nations convention against corruption on corruption perceptions index scores
(University of Western Cape, 2019)This paper examines the impact early ratification of the United Nations Convention against Corruption has on a country’s Corruption Perceptions Index score. It builds on much of the recent scholarly work that explores ... -
Corruption in Kenya during the Covid-19 pandemic and the right to health: Lessons learnt and future prospects
(University of the Western Cape, 2022)Kenya has made positive strides in fighting corruption through signing and ratifying the United Nations Convention Against Corruption and the African Union Convention on Prevention and Combating Corruption. These Conventions ... -
Corruption in the new public procurement regime in Nigeria
(University of the Western Cape, 2018)Corruption in the public procurement system has been a major obstacle to Nigeria’s economic development and, as such, it has remained one of the prime concerns of successive governments, both military and civilian, since ... -
Corruption in the prison context
(Civil Society Prison Reform Initiative, 2006)The point of departure of this paper is that, in general, corruption is a human rights issue, which is accentuated in the prison context given the nature of imprisonment. Three factors create an intrinsic risk for corruption ... -
The COS-Halos survey: Rationale, design and a census of circumgalactic neutral hydrogen
(IOP Publishing, 2013)We present the design and methods of the COS-Halos survey, a systematic investigation of the gaseous halos of 44 z = 0.15–0.35 galaxies using background QSOs observed with the Cosmic Origins Spectrograph aboard the Hubble ... -
Cosmic evolution of star-forming galaxies to z 1.8 in the faint low-frequency radio source population
(Oxford University Press, 2019)We study the properties of star-forming galaxies selected at 610 MHz with the GMRT in a survey covering ∼1.86 deg2 down to a noise of ∼7.1 μJy beam−1. These were identified by combining multiple classification diagnostics: ... -
The cosmic evolution of the IMF under the Jeans conjecture with implications for massive galaxies
(Oxford University Press, 2013)We examine the cosmic evolution of a stellar initial mass function (IMF) in galaxies that varies with the Jeans mass in the interstellar medium, paying particular attention to the K-band stellar mass-to-light ratio (M/LK) ... -
Cosmic microwave background constraints on a physical model of reionization
(Oxford University Press, 2021)We study constraints on allowed reionization histories by comparing predictions of a physical seminumerical model with secondary temperature and polarization anisotropies of the cosmic microwave background (CMB). Our model ... -
Cosmic sands: the origin of dusty, star-forming galaxies in the epoch of reionization
(The astrophysical journal, 2023)We present the Cosmic Sands suite of cosmological zoom-in simulations based on the simba galaxy formation model in order to study the buildup of the first massive and dusty galaxies in the early universe. Residing in the ... -
Cosmological 3D Hi Gas Map with HETDEX Lyα Emitters and eBOSS QSOs at z = 2: IGM-Galaxy/QSO Connection and a ∼ 40-Mpc Scale Giant Hii Bubble Candidate
(IOP Publishing, 2020)We present cosmological (30−400 Mpc) distributions of neutral hydrogen (H i) in the intergalactic medium (IGM) traced by Lyα emitters (LAEs) and QSOs at z = 2.1–2.5, selected with the data of the ongoing Hobby–Eberly ... -
Cosmological baryon transfer in the SIMBA simulations
(Oxford University Press, 2019)We present a framework for characterizing the large-scale movement of baryons relative to dark matter in cosmological simulations, requiring only the initial conditions and final state of the simulation. This is performed ... -
Cosmological constraints from the EFT power spectrum and tree-level bispectrum of 21 cm intensity maps
(Elsevier B.V., 2024)We explore the information content of 21 cm intensity maps in redshift space using the 1-loop Effective Field Theory power spectrum model and the bispectrum at tree level. The 21 cm signal contains signatures of dark matter, ... -
Cosmological constraints from the power spectrum and bispectrum of 21cm intensity maps
(IOP Publishing, 2022)The 21cm emission of neutral hydrogen is a potential probe of the matter distribution in the Universe after reionisation. Cosmological surveys of this line intensity will be conducted in the coming years by the SKAO and ... -
