Classes of Dunford-Pettis-type operators with applications to Banach spaces and Banach lattices
(North-West University (South Africa), Potchefstroom Campus, 2017)The aim of this study is to extend existing knowledge of Dunford-Pettis operators on Banach spaces and Banach lattices and their variants. Using the concept of p-convergent operators as basis, we introduce the ... -
Classification of Fischer type metal carbenes
(North-West University (South Africa), 2016)Fischer type metal carbene complexes are used as catalysts in various organic synthesis reactions, e.g. metathesis, cyclopropanation and benzannulation. Nevertheless, the mechanisms of the above-mentioned reactions are ... -
The Classification of Plant Communities and the Evaluation of Restoration Technologies in Different Land-Use Areas in the Vhembe-Dongola National Park, Northern Province, South Africa
(North-West University (South Africa), 2002)The establishment of the Vhembe-Dongola National Park has been an objective of the South African National Parks for many years. The ultimate objective is that the Vhembe-Dongola National Park would become a major component ... -
Classification of water resources within Quaternary Catchment C22K
(North-West University (South Africa), 2019)The Vaal Barrage was built by Rand Water downstream of the Vaal Dam. The Vaal River Scheme, in many respects, brought about a change in the environment along the Vaal River between the Barrage and Vereeniging. Vereeniging ... -
The clean development mechanism’s contribution towards sustainable development in South Africa : the Bisasar Landfill case study
(North-West University, 2018)The Clean Development Mechanism (CDM) was established under Article 12 of the Kyoto Protocol to assist developed countries (countries listed in Annex I of the Protocol) to reduce their greenhouse gas (GHG) emissions by ... -
Clifford-Fischer Matrices and character tables of certain group extensions associated with M₂₂:2, M₂₄ and HS:2
(North-West University (South Africa), 2016)Character tables of finite groups provide substantial information about a group and their use is of great importance in physical sciences and pure mathematics. Any finite group is either simple or has a proper normal ... -
Climate Change and Variability Effects on Malaria Prevalence in the Limpopo Province, South Africa
(North-West University (South Africa), 2015)As the world strives towards the elimination of the highest death causing vector-borne disease, namely malaria, research is needed in order to contribute towards this goal in South Africa. This study contributes towards ... -
The Climatology of heat waves in the North West Province, South Africa
(North-West University (South Africa), 2020)The overall objective of this dissertation was to develop a heat wave climatology in North West Province (NWP) of South Africa (SA) through analysing maximum temperature and subsequent atmospheric parameters during the ... -
Cloning and evaluation of expression of the open reading frames of a South African G9P[6] rotavirus strain encoding rotavirus structural proteins VP2 and VP6 in bacteria and yeast
(2015)Rotavirus infection causes severe gastroenteritis, affecting all children under the age of five regardless of hygiene or water quality. The currently licensed vaccines succeeded in reducing diarrhoea worldwide, but they ... -
Cloning and expression of human recombinant isoform a of glycine–N–acyltransferase
(North-West University, 2012)Awareness of detoxification, nowadays known as biotransformation, has become an integral part of our daily lives. It is a modern buzz word that is used to promote anything from health food to enhancement of performance in ... -
Cloning and expression of recombinant bovine glycine N-acyltransferase from bovine liver
(North-West University (South Africa), Potchefstroom Campus, 2011)The importance and social focus on detoxification and improving a person’s lifestyle has increased tremendously over the years. This is due to increasing levels of pollution and the resulting increase of foreign chemicals ... -
Cloning viral dsRNA genomes : analysis and application
(North-West University, 2004)Double-stranded RNA viruses occur in a large number of hosts in nature ranging from bacteria to mammals. Molecular studies of the double-stranded RNA viruses have greatly enhanced man's understanding of this large group ... -
A closer look at potential exoplanet targets from the Nooitgedacht Observatory
(North-West University (South Africa), 2023)Exoplanet surveys like KELT and TESS often require follow-up observations with a traditional, ground based telescope to confirm whether a potential candidate is indeed an exoplanet or not. The optical telescope at the ... -
Co-adsorption of phenol and calcium from an industrial wastewater stream
(North-West University (South Africa), 2020)The pulp and paper industries are large producers of industrial wastewater that contain both organic and inorganic pollutants that influence water quality and availability. Conventional wastewater treatment methods such ... -
