Grammatical constraints and motivations for English/Afrikaans codeswitching: evidence from a local radio talk show
(University of the Western Cape, 2006)The study investigated the practice of codeswitching within the Cape Flats speech community of Cape Town. Members of this speech community have always been exposed to both English and Afrikaans in formal as well as informal ... -
"Grammatical controversy on the temporality of the imperfect tense in the Qur’ānic text" Is it Mu’rab (declinable) or Mabnī (indeclinable)?
(University of the Western Cape, 2018)This research discusses the temporality of Al-Fi’l Al-Moḍāri’ (present tense) in Arabic in terms of structure and case endings. It also focuses on the time of the imperfect tense and how it is affected by the Adawāt ... -
Grand corruption in Swaziland : a critical analysis of the state's response
(University of the Western Cape., 2011)Corruption has crippled many economies, with developing countries being the hardest hit and the Kingdom of Swaziland being no exception. The government of Swaziland loses millions monthly through corruption and the figure ... -
Granivores as ecosystem regulators of woody plant increasers in semi-arid Savannas of the Lowveld, South Africa
(University of the Western Cape, 2006)In recent years, a global trend of increasing woody vegetation densities in semi-arid savanna habitats has been recorded, commonly described in South Africa as 'bush encroachment'. The shrubs and trees that do this ... -
Granting intellectual property rights on life forms and processes: does it ensure food security? A developing country perspective
(University of the Western Cape, 2005)This study critically investigated the argument whether intellectual property rights over life forms and processes would ensure food security. It only considered the issue from the perspective of developing countries, as ... -
Graphenated electrode protocol for electrochemical nanosensing of 17β- estradiol as an environmental estrogeneous endocrine disruptor
(University of the Western Cape, 2016)17β-Estradiol can be defined as an endocrine disruptor chemical with estrogenic activity, which can bind to the estrogen receptor in the body and potentially alter the normal physiological function of the endocrine ... -
Graphenated organic nanoparticles immunosensors for the detection of TB biomarkers
(University of the Western Cape, 2017)Pulmonary Tuberculosis (TB) a disease second to HIV/AIDS is a global health problem that arises in two states; as an active state and as a latent state. Diagnosis of active TB is tedious and requires expensive procedures ... -
Graphenated polyaniline nanocomposite for the determination of polyaromatic hydrocarbons (pahs) in water
(2013)The thesis presents a simple, sensitive, low cost and a novel graphenated polyaniline doped tungsten trioxide nanocomposite, as an electrochemical sensor for the detection and quantitative and determination of PAHs, which ... -
Graphene based materials for carbon capture
(University of Western Cape, 2020)The adverse effects of CO2 and greenhouse gas emissions into the atmosphere is believed to be one of the causes of climate change. The seriousness of global warming is encouraging the development of technologies designed ... -
Graphene based nano-coatings: synthesis and physical-chemical investigations
(UWC, 2012)It is well known that a lead pencil is made of graphite, a naturally form of carbon, this is important but not very exciting. The exciting part is that graphite contains stacked layers of graphene and each and every layer ... -
