Use of remotely sensed data to estimate tree species diversity as an indicator of biodiversity in BloubergNature Reserve, South Africa
(Taylor and Francis Group, 2022)We use remotely sensed data to estimate species diversity inBlouberg Nature Reserve (BNR) in the Limpopo province, SouthAfrica to understand the state of biodiversity since communities’involvement in conservation initiatives. ... -
Use of remotely sensed derived metrics to assess wetland vegetation responses to climate variability-induced drought at the Soetendalsvlei wetland system in the Heuningnes Catchment, Western Cape province, South Africa
(Taylor and Francis Group, 2021-11-11)Wetland vegetation plays an important role in the environmental functioning of wetlands through the provision of ecosystem services, such as food and critical habitat for organisms that live in or near water resources. The ... -
The use of stable isotopes to identify surface water–groundwater interaction in the Kruger National Park, South Africa
(South African Water Research Commission, 2023)The role of groundwater, in general, is often overlooked in freshwater ecosystem management policies and in the management of South Africa’s flagship conservation area, the Kruger National Park (KNP). To address this gap, ... -
The use of ultraviolet radiation as a non-thermal treatment for the inactivation of alicyclobacillus acidoterrestris spores in water, wash water from a fruit processing plant and grape juice concentrate
(CUT Free State, 2013)Alicyclobacillus acidoterrestris is a non-pathogenic, spore-forming bacterium that can survive the commercial pasteurisation processes commonly used during fruit juice production. Surviving bacterial endospores germinate, ... -
User interfaces for communication bridges across the digital divide
(Springer-Verlag, 2006)Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centred approach to learn how interaction techniques can compensate for poor communication across ... -
Using a disciplinary discourse lens to explore how representations afford meaning making in a typical wave physics course
(Springer Verlag, 2013)We carried out a case study in a wave physics course at a Swedish university in order to investigate the relations between the representations used in the lessons and the experience of meaning making in interview–discussions. ... -
Using a mHealth system to recall and refer existing clients and refer community members with health concerns to primary healthcare facilities in South Africa: a feasibility study
(Taylor & Francis, 2020)Background: Lay health workers (LHWs) are critical in linking communities and primary healthcare (PHC) facilities. Effective communication between facilities and LHWs is key to this role. We implemented a mobile health ... -
Using a multiple-delivery-mode training approach to develop local capacity and infrastructure for advanced bioinformatics in Africa
(Public Library of Science, 2021)With more microbiome studies being conducted by African-based research groups, there is an increasing demand for knowledge and skills in the design and analysis of microbiome studies and data. However, high-quality ... -
Using a simulation software to perform energy and exergy analyses of the sulfur-iodine thermochemical process
(World Scientific Publishing, 2017)The objective of this work is to demonstrate the utilization of the power of simulation tools to perform an exergy analysis of a process. Exergy analysis, being a new and useful thermodynamics tool, will be applied to one ... -
Using cloud computing techniques to monitor long-term variations in ecohydrological dynamics of small seasonally-flooded wetlands in semi-arid South Africa.
(Journal of Hydrology, 2022)Wetlands in drylands have high inter- and intra-annual ecohydrological variations that are driven to a great extent by climate variability and anthropogenic influences. The Ramsar Convention on Wetlands encourages the ... -
Using multiplex amplicon pcr technology to efficiently and timely generate rift valley fever virus sequence data for genomic surveillance
(MDPI, 2023)Rift Valley fever (RVF) is a febrile vector-borne disease endemic in Africa and continues to spread in new territories. It is a climate-sensitive disease mostly triggered by abnormal rainfall patterns. The disease is ... -

Using sap flow data to assess variations in water use and water status of apple orchards of varying age groups in the western cape province of South Africa
(Water Research Commission, 2020)No accurate quantitative information currently exists on how water use of apple (Malus domestica) orchards varies from planting to full-bearing age, leading to poor irrigation and water allocation decision making. This ... -
Using sparse gaussian processes for predicting robust inertial confinement fusion implosion yields
(arXiv, 2019)Here we present the application of an advanced Sparse Gaussian Process based machine learning algorithm to the challenge of predicting the yields of inertial confinement fusion (ICF) experiments. The algorithm is used ... -
Using the water balance approach to understand pool dynamics along non-perennial rivers in the semi-arid areas of South Africa
(Elsevier, 2022)The Touws River in the Klein Karoo region of South Africa Study focus: This study sought to improve the understanding of pool dynamics along non-perennial rivers (NPRs) by utilising the water balance approach to assess the ... -
Using voice over IP to bridge the digital divide: a critical action research approach
(Telkom, 2003)There is a great disparity between those who have access to Information and Communication Technologies (ICTs) and those that do not. This phenomenon forms part of the Digital Divide. Many ICTs may be used to help overcome ... -
Using wearable sensors for remote healthcare monitoring system
(Scientific Research Publishing, 2011)Recent technological advances in wireless communications and wireless sensor networks have enabled the design of low-cost, intelligent, tiny, and lightweight medical sensor nodes that can be strategically placed on human ... -
Utilisation of cover crops: implications for conservation agriculture systems in a mediterranean climate region of South Africa
(Springer, 2021)Purpose Cover crops can provide multiple agroecosystem services to crops produced in conservation agriculture systems. South African grain producers in the Mediterranean climate region are reluctant to integrate cover ... -
