International Mother Language Day Celebration 2021

23 March 2021 | Story Mbali Moiketsi

The Office for International Affairs recently celebrated International Language Day. This year, we invited all faculties to submit the names of people who would be willing to contribute video clips to educate us about their mother tongue. The videos submitted were from diverse academic staff members and postdoctoral fellows currently based in different parts of the world. Extensive research has created this edutainment video, featuring famous language quotes, indigenous languages across the African continent, and business languages used across the African continent. Some of the indigenous languages on the African continent are fading away, caused by colonial influence.

Fun facts:
From 1994 to 2013, South Africa was in the Guinness Book of World Records for most official languages. These are Afrikaans, English, Ndebele, Sepedi, Sesotho, Swati, Tsonga, Tswana, Venda, Xhosa, and Zulu.

Since the adoption of the 2013 Constitution, Zimbabwe now holds this title with 16 official languages, namely Chewa, Chibarwe, English, Kalanga, Koisan, Nambya, Ndau, Ndebele, Shangani, Shona, Sign Language, Sotho, Tonga, Tswana, Venda, and Xhosa. Zimbabwe therefore now holds the Guinness World Record for the country with the largest number of official languages.

Albeit the main languages in Zimbabwe are English, Shona and Ndebele, the minor languages are Chewa, Chibarwe, Kalanga, Koisan, Kunda, Lozi, Manyika, Nambya, Ndau, Nsenga, Tsonga-Shangani, Sotho, Tjwao, Tonga, Tswa, Tswana, Venda, and Xhosa.

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.
