(University of the Western Cape, 2015)Background: The effectiveness of the combined oral contraceptive pill as a family planning method is dependent on its quality. The quality of medicines on the healthcare market is established through postmarket quality ... -
Quantified assessment to enhance student learning in the sciences at UWC
(University of the Western Cape, 2005)This project discusses whether the British prototype questionnaire called the Assessment Experience Questionnaire (AEQ) could be standardized as a quantifier of assessment and be used at a multicultural institute such as ... -
Quantifying competition in two co-occurring southern African psammophiinae snakes: Psammophis crucifer and psammophylax r. Rhombeatus
(University of Western Cape, 2020)Studies on snake competitive interactions have relatively been well documented globally, however, those examples tend to be dominated by non-African examples. Africa has a large and spectacular reptile diversity and yet ... -
A quantitative and qualitative assessment of dental aerosols within a dental clinical unit: An avenue for the transmission of resistant nosocomial infection.
(University of Western Cape, 2020)Introduction: Nosocomial infections are infections that occur 48 hours after receiving care for an unrelated condition in a clinic or a hospital environment, many of which are resistant to at least one of the drugs most ... -
Quantum dot sensitized estrogen receptor alpha-recombinant protein electrochemical biosensor for 17-beta estradiol
(University of the Western Cape, 2016)Estrogens play an extraordinary role in the endocrine system regulation through the stimulation and regulation of endocrine pathways. 17β-estradiol is one of the final metabolites in estrogen regulation by hydroxylase ... -
Quantum dots for multiplexed biological imaging
(University of the Western Cape, 2023)Over the past two decades, indium phosphide (InP) colloidal quantum dots (QDs) have attracted substantial interest as a possibly less hazardous alternative to cadmium-based QDs. The improvements in their colloidal synthesis ... -
Quantum dots genosensor for Her2/Neu oncogene - a breast cancer biomarker
(University of the Western Cape, 2014)The human epidermal growth factor receptor (HER)-family of receptor tyrosine kinases; human epidermal growth factor receptor 1, human epidermal growth factor receptor 2, human epidermal growth factor receptor 3 and human ... -
Quantum dots-amplified electrochemical cytochrome P450 phenotype sensor for tamoxifen, a breast cancer drug
(University of the Western Cape, 2017)Breast cancer is regarded as the most common cancer in South Africa and its rate of occurrence is increasing. About one in every 31 South African women are at the risk of developing breast cancer and early diagnosis and ... -
Quasi-uniform and syntopogenous structures on categories
(University of the Western Cape, 2019)In a category C with a proper (E; M)-factorization system for morphisms, we further investigate categorical topogenous structures and demonstrate their prominent role played in providing a uni ed approach to the theory ... -
Radiation-induced Leukaemia in South Africa: Response of lymphocytes and cd34+ cells to different radiation qualities
(University of the Western Cape, 2020)Epidemiological studies have highlighted that leukaemia can be considered as the most prominent malignancy after radiation exposure during childhood. The lifetime risk on radiation-induced leukaemia for a given dose is 3 ... -
