The research efforts in the Department of Cardiothoracic Surgery in the Faculty of Health Sciences, UFS, have come a long way since the establishment of a homograft bank, animal research, and laboratory-based research on cardioplegia by Prof Hannes Meyer in the 1980s

Several world-class scientists and academics in the field of cardiovascular research will converge at the University of the Free State (UFS) on Thursday (5 May 2022) for a one-day hybrid conference to explore and celebrate the massive strides made in this critical field at the UFS Robert W M Frater Cardiovascular Research Centre.

The research efforts in the Department of Cardiothoracic Surgery in the Faculty of Health Sciences, UFS, have come a long way since the establishment of a homograft bank, animal research, and laboratory-based research on cardioplegia by Prof Hannes Meyer in the 1980s. Renewed interest in 2004 under the leadership of Prof Francis E Smit culminated in the establishment of the Robert W M Frater Cardiovascular Research Centre (the Frater Centre) in 2015. This was made possible through donor funding, especially by Dr Robert W M Frater MD PhD (honoris causa, UFS), a South Africa-born New York-based cardiothoracic surgeon, researcher and innovator as infrastructure and project support by the UFS.

The vision of the Frater Centre is to be a leading cardiovascular research institution in South Africa and sub-Saharan Africa. It provides an interdisciplinary training and research platform for scientists and clinicians from different backgrounds to develop as researchers and collaborators in cardiovascular and thoracic surgery and related domains. Activities are focused on the development of African solutions for African problems.

Three main divisions
The Frater Celebration day will highlight the achievements made thus far in a hybrid format in four sessions, which can be attended on a virtual platform or in person. The centre’s local and international collaborators will participate in the programme, and Dr Ronnie van der Merwe, the Group CEO of Mediclinic International, is the guest of honour.

The Frater Centre consists of three main divisions, all of which will form part of the focus of the conference programme in various forms during the day:

1) The Clinical Research Division addresses cardiovascular disease on a broad front, ranging from population and prevalence studies, healthcare solutions and clinical outcomes studies in a specific South African and African context.

2) The Research, Development and Commercialisation division is divided into Tissue Engineering and Cell Biology, Tissue Banking and Large Animal studies, and bioengineering to develop African solutions and technology within these domains.

3) The Simulation Programme provides an integrated interdisciplinary platform for the education and training of individuals and teams in cardiovascular, thoracic, anaesthetic, perfusion technology and related nursing fields in a state-of-the-art simulation unit. The research centre is developing a unique and leading programme and systems in this field. This endeavour is also developing IT models for training, evaluation and research.

The Frater Centre and 4IR
The Centre is firmly established in the fourth industrial revolution. It is new technology-driven, creating new IT platforms and boasts extensive interdisciplinary projects at the biomedical sector's local, national, and international levels.

It is essential to note that the extensive and successful collaboration within the Frater Centre not only exists on institutional level but also nationally and internationally. These collaborators assist, mentor, direct and contribute to the research activities.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
