Quality of HIV counselling in South Africa
(Kamla-Raj, 2015)HIV counselling and testing (HCT) has become increasingly available in South Africa since the 1990s. Over 4500 public health facilities offer client and provider-initiated HIV counselling and testing. Counselling and testing ... -
Quality of home-based rapid HIV testing by community lay counsellors in a rural district of South Africa
(International Aids Society, 2013)INTRODUCTION: Lack of universal, annual testing for human immunodeficiency virus (HIV) in health facilities suggests that expansion of HIV testing and counselling (HTC) to non-clinical settings is critical to the achievement ... -
Quality of life amongst young adults with stroke living in Kenya
(Makerere University Medical School, 2013)BACKGROUND: The world has been experiencing an increase of stroke among young adults. Occurrence of stroke in young adults dramatically affects the quality of life of the individuals. OBJECTIVES: To investigate the quality ... -
The quality of life of HIV-infected and non-infected women post-caesarean section delivery
(AOSIS OpenJournals Publishing AOSIS (Pty) Ltd, 2017)There is a dearth of literature on the postnatal quality of life (QoL) of women. This study aimed to determine to QoL of HIV-infected and non-infected women post-caesarean section delivery. This prospective, longitudinal ... -
Quantification and characterisation of microplastics ingested by selected juvenile fish species associated with mangroves in KwaZulu- Natal, South Africa
(Elsevier, 2020)Though the number studies on microplastic ingestion by fish is growing, data on fish species charac- teristic of the South African coastline are scarce. This study quantified and characterised (physically and chemically) ... -
Quantification and identification of sperm subpopulations using computer-aided sperm analysis and species-specific cut-off values for swimming speed
(Taylor & Francis, 2013)Motility is an essential characteristic of all fl agellated spermatozoa and assessment of this parameter is one criterion for most semen or sperm evaluations. Computer-aided sperm analysis (CASA) can be used to measure ... -
A quantification mechanism for assessing adherence to information security governance guidelines
(Emerald, 2022)Boards of Directors and other organisational leaders make decisions about the information security governance systems to implement in their companies. The increasing number of cyber-breaches targeting businesses makes ... -
Quantification of radicals generated in a sonicator
(Iranian Chemical Society, 2016)The hydroxyl radical (OH•) is a powerful oxidant produced as a consequence of cavitation in water. It can react nonspecifically in breaking down persistent organic pollutants in water into their mineral form. It can also ... -

Quantifying the contribution of riparian total evaporation to streamflow transmission losses: Preliminary investigations along the Groot Letaba river
(Elsevier, 2019-11-08)The Groot Letaba River, situated in the semi-arid north-eastern region of South Africa is an example of a river system in which the uncertainty associated with transmission losses (TL) has limited the effective management ... -
Quantitative assessment of heavy metal effects on sperm function using computer‐aided sperm analysis and cytotoxicity assays
(Wiley, 2018)One known environmental risk factor impacting on human reproduction is heavy metal pollution. Although some metals (e.g., Cu, Se and Zn) have protective effects on the male reproductive system in low doses, heavy metals ... -
A quantitative in-depth analysis of the prototype sdB+BD system SDSS J08205+0008 revisited in the Gaia era
(Oxford University Press, 2021)Subdwarf B stars are core-helium-burning stars located on the extreme horizontal branch (EHB). Extensive mass loss on the red giant branch is necessary to form them. It has been proposed that substellar companions could ... -
Quantitative sperm characteristics of Tankwa goats with special reference to hyperactivated motility
(South African Society for Animal Science, 2020)Computer-assisted semen analysis (CASA) is an automated and objective method of evaluating structural (e.g. morphology) and functional sperm parameters (e.g. motility and hyperactivation). Sperm hyperactivation is essential ... -
Quantitative study on the changes of Karst groundwater level and hydrochemistry in Jinci spring catchment, Shanxi, China
(Springer Nature, 2020)Since Jinci spring ceased to flow on April 30, 1994, it has never been reflowed, which seriously affects the sustainable utilization of karst groundwater. The purpose of this paper is to provide the basis for the reflow ... -
Quantum dot nanotoxicity investigations using human lung cells and toxor electrochemical enzyme assay methodology
(American Chemical Society, 2017)Recent studies have suggested that certain nanomaterials can interfere with optically based cytotoxicity assays resulting in underestimations of nanomaterial toxicity. As a result there has been growing interest in the ... -
Quantum dot-sensitised estrogen receptor-α-based biosensor for 17β-estradiol
(MDPI, 2023): 17β-estradiol (E2) is an important natural female hormone that is also classified as an estrogenic endocrine-disrupting compound (e-EDC). It is, however, known to cause more damaging health effects compared to other ... -
A quarter century of marine biodiscovery in Algoa bay, South Africa
(Journal of Natural Products, 2023)Algoa Bay, the largest crenulate bay on the south-eastern coast of South Africa, is currently one of the most well-studied marine ecosystems in southern Africa. A plethora of endemic marine invertebrates inhabits the benthic ... -
Quartering the city in discourse and bricks: Articulating urban change in a South African enclave
(Springer, 2016)Focusing on the urban enclave in Cape Town known as De Waterkant, this paper examines the product and process of ‘quartering’ urban space—shaping urban space as the locus for the symbolic framing of culture. This paper ... -

Quasi-uniform structures determined by closure operators
(Elsevier, 2021)We demonstrate a one-to-one correspondence between idempotent closure operators and the so-called saturated quasi-uniform structures on a category C. Not only this result allows to obtain a categorical counterpart P of the ...
