Cultivating the land-Mpho Twala.

The Bachelor of Community Development qualification offered on the Qwaqwa Campus develops young professionals who are able to work collaboratively with the community to come up with initiatives that build resilience and sustainability. Before obtaining their qualifications, students are required to identify community needs and to come up with viable ways to eradicate these.

It was during this period that Mpho Twala, a recent CommDev graduate, identified a once-thriving community vegetable garden that had been abandoned and subsequently stripped over the years. Further research led her to realise that the soil was still very fertile, and with a bit of work, could once again be revived to become an income-generating business. She received her qualification during the April graduations on the Qwaqwa Campus, but she did not stop there.

Bringing change to the community through vegetable farming

Twala, with no agricultural background, approached the locals for permission to revive the 1-ha garden into a community-owned vegetable garden. “The land has been uncultivated for more than a decade, and after conducting a needs analysis, I didn’t want to leave it like that, because I saw that if I worked with young people, this would help with the high unemployment rate among the youth in this area,” Twala said.

She says she was driven by bringing about change in her community, which she believes was inspired by her studies.
“I’ve always wanted to do something in my community, and CommDev taught me to see opportunities instead of challenges.”

The vegetable garden currently has 17 employees, 10 of whom are under the age of 35. They are currently harvesting cabbages, various forms of spinach, and white onion – all organic – for home consumption and community purchasing. They also occasionally sell to hawkers around Qwaqwa.

Twala dreams of expanding the garden, adding more crops, and ultimately reaching commercial level. “We are currently classified under subsistence farming – farming for home consumption and selling the surplus so that the project can remain operational. But with the right funding and support, we can grow bigger and better.”

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
