Haemophilia workshop the first of its kind at UFS
The UFS Department of Haematology and Cell Biology is producing quality medical graduates, addressing the high demand for trained graduates. Dr Anneke van Marle, Haematologist in the department, presented a lecture to final-year medical students on muscle and soft-tissue bleeding in haemophilia.

The Medical and Scientific Advisory Council (MASAC) of the South African Haemophilia Foundation (SAHF) has identified a need for more in-depth training of junior doctors on the basic aspects of the bleeding disorder haemophilia. 

Addressing this need in the sector, the Department of Haematology and Cell Biology at the University of the Free State (UFS) recently hosted a training workshop specifically targeting final-year medical students before they enter practice.

The Novo Nordisk Haemophilia Foundation is sponsoring this countrywide haemophilia training.

According to Jaco Joubert, Senior Lecturer and Pathologist in the Department of Haematology and Cell Biology, the department is very active in the field of haemophilia treatment, research and training, with representation on the Executive Committee of the Medical and Scientific Advisory Council of the South African Haemophilia Foundation.

Function with confidence

“The UFS Department of Haematology and Cell Biology has taken a proactive approach, by being the first department in South Africa to offer this training course to final-year medical students at the UFS; an investment in the future. The department runs the Bloemfontein Haemophilia Treatment Centre – which is the main haemophilia treatment and referral centre for patients from the Free State and Northern Cape. It is therefore ideally positioned to offer such training to students,” said Joubert.

Proactive role

The training workshop empowered and equipped students with more extensive knowledge on the practical aspects of managing patients with haemophilia; the various treatment products currently available in South Africa and laboratory diagnostic approaches in complicated cases. “This will enable students to function with more confidence during their internship and community service years,” said Joubert. 

He believes a training workshop of this calibre showcases the proactive role the department and the university is taking in the advancement of haemophilia training in South Africa.

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.
