Ntebohiseng Sekhele hopes her PhD study will address conservation conflicts that exist between communities and protected areas.

The University of the Free State’s Afromontane Research Unit (ARU) based on the Qwaqwa Campus has recently concluded the process of recruiting candidates for the University Capacity Development Programme (UCDP). Through this programme, two historically disadvantaged South African universities; Universities of the Free State (Qwaqwa Campus) and Venda (UNIVEN) and three universities in the United States will be collaborating on a number of PhD research projects.

“The programme is funded through the US-SA Higher Education Network and will give candidates and their supervisors the opportunity to regularly travel to the USA and spend time at participating US universities where their co-promoters will be based and allow them to collaborate with identified suitable academics based at those institutions,” said Prof Geofrey Mukwada, Associate Professor in Geography and the coordinator of the project.

One of the young academics selected for this is Ntebohiseng Sekhele from the Geography Department. She will be doing her research in collaboration with the Colorado State University.

“I am delighted to be part of this programme and it still feels like a dream. I feel honored to be selected to participate in such a prestigious programme. To be chosen amongst other applicants means the coordinators believe in my potential, and I look forward to working towards my full potential,” said Sekhele, who describes herself as ‘a simple and ambitious village girl from Monontsha in Qwaqwa.’ 

Sekhele’s proposed PhD study will focus on determining strategies and impacts of conservation practices by the local communities. “It will address conservation conflicts that exist between communities and protected areas; different interpretations of sustainability (including indigenous knowledge) and offer recommendations of harmonising the conservation practices with the sustainability of conservation areas. There is a great need to develop management strategies that will simultaneously satisfy conservation and human needs. She will be graduating with an MSc (Environmental Geography) degree in 2019.

Other US universities involved in the UCDP are Appalachian State University (ASU) and University of Montana (UoM).

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.
