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 ... -

(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 ... -
Radical possibilities at the crossroads of African feminism and digital activism
(University of the Western Cape, 2022)Studies abound that deal with digital activism and social movements worldwide. Many African scholars continue to dwell on how the effects of technological advancement and access to social media are ingrained in class and ... -
Radicals and Antiradicals in near-rings
(1979)This thesis deals with Jacobson type radicals and ideals, which are antiradical in the sense that they are direct sums of minimal left ideals and annihilate the quasi-radical of central importance are the s-radical denoted ... -
Radio frequency spectrum monitoring: Officers' acceptance of monitoring technologies such as fixed direction finders
(University of the Western Cape, 2006)The research focuses on the acceptance of new technologies within the telecommunications industry. The study examines three models namely Innovation theory, Theory of Reason Action (TRA), and Technology Acceptance Model ... -
Radio-optical analysis of extended radio sources in the first look survey field
(2010)I combine 610 MHz Giant Metrewave Radio Telescope (GMRT) data, 1.4 GHz Very Large Array (VLA) data and 1.4 GHz Westerbork Synthesis Radio Telescope (WSRT) observations, encompassing a ∼ 4 square degree field (sq. deg. ... -
A radiographic analysis of the anterior palate as a donor site for bone harvesting
(University of the Western Cape, 2015)Autologous bone grafting in conjunction with dental implant therapy is a well-accepted procedure in oral and maxillofacial rehabilitation. A variety of intraoral donor sites, such as the mandibular symphysis, the mandibular ... -
A radiographic comparison of the proclination of mandibular incisors between Class II extraction and non-extraction cases using the Damon® self-ligating system
(University of Western Cape, 2021)The stable position of the mandibular incisors, and the extent to which their spatial position may be changed in the sagittal plane, represents a key point in determining orthodontic treatment goals and objectives. According ... -
Radiographic profile of symptomatic impacted mandibular third molars in the Western Cape, South Africa
(University of the Western Cape, 2005)It is common practice to remove impacted mandibular third molars due to pathology associated with these impactions. Alternatively, impactions can be treated conservatively through a closely guarded follow-up regiment. ... -
Radiometric characterisation of vineyard soils, Western Cape, South Africa
(University of the Western Cape, 2010)This study is aimed at investigating the feasibility of using the radiometric technique as an alternative to traditional methods for determining soil physico-chemical parameters which are important for terroir characterization. ... -
Radiometric investigation of soil and beach sand in Zanzibar
(University of the Western Cape, 2020)This study presents the results of radiometric investigation of soil and beach sand in Zanzibar. The activity concentration of natural radionuclides (40K, and 232Th and 238U decay products) in beach sand and soil samples ... -
Radiometric study of beach sand deposits along the coast of Western Cape province, South Africa
(2007)Natural radioactivity studies have been carried out to study the textural characteristics, heavy mineral composition, provenance, sediment transport, and depositional environment of beach placer deposits. The naturally ... -
Radiometric study of soil: the systematic effects
(University of the Western Cape, 2007)The natural 238U, 232Th and 40K radioactive content of vineyard soil was measured with an in-situ gamma-ray detector. The activity concentrations measured with the in-situ detector are normalized using the laboratory-determined ... -
Radioprotective effects of rooibos herbal tea on the developing central nervous system of wistar rats
(University of the Western Cape, 2018)Background: Early postnatal radiation exposure from environmental, diagnostic or therapeutic sources is potentially deleterious to the developing nervous system resulting in oxidative stress, structural damage, altered ... -
Radiosensitization effects of gold nanoparticles in proton therapy
(University of the Western Cape, 2017)Despite recent advances in radiotherapy, some tumours have shown to be resistant to treatment and patients still experience long term side effects. Gold nanoparticles (AuNPs) have been identified as effective radiosensitizers ... -
Radon escape from water
(University of the Western Cape, 2010)This thesis aims to measure the rate of radon loss from water in a systematic way. The dependence on surface area, temperature and concentration will be investigated. The experiments were done at UWC by creating radon using ... -
Radon exhalation of building materials
(University of the Western Cape, 2018)Public concern about all radiation and radon exhalation from building materials has been highlighted recently. The purpose of this study is to address this public concern and to investigate the contribution of building ... -
Radon exhalation studies for applications in low background environments.
(University of the Western Cape, 2022)Neutrinoless double beta decay (0 ) is a rare process that is yet to be observed. Observation of neutrinoless double beta decays would imply lepton number violation, and that the neutrino is its own antiparticle ... -
Radon exhalation studies for applications in low background environments.
(University of the Western Cape, 2023)Neutrinoless double beta decay (0νββ) is a rare process that is yet to be observed. Observation of neutrinoless double beta decays would imply lepton number violation, and that the neutrino is its own antiparticle (a Majorana ... -
Radon in the Cango Caves
(University of the Western Cape, 2005)Radon is a naturally occurring radioactive element in the 238U decay series that is found in high concentrations in certain geological formations such as Caves. Exposure to high concentrations of radon has been positively ...
