Katleho Nkosi’s design, which won him second place in the national design competition during the Student Entrepreneurship Week 2022.

Katleho Nkosi, a fourth-year Education student at the University of the Free State (UFS), obtained second place in a national design competition hosted virtually by Entrepreneurship Development in Higher Education (EDHE). 

The national design competition formed part of the launch of the Student Entrepreneurship Week 2022, which took place at the University of Venda on 18 August 2022. As such, students from many of the universities in the country, including Nkosi, took part in designing a poster that would be used to advertise the event. 

Nkosi is delighted and excited about this accomplishment. “This win was really surprising and unbelievable for me, because obtaining the second-place position means that my work is good,” said Nkosi.

The participants were allowed to conceptualise and submit their final product between 28 June and 15 July 2022. “I had no experience in this space, I only designed content for fun, and I participated in this competition because I was motivated by a friend,” Nkosi highlighted.

The motivation behind the design

Since the Student Entrepreneurship Week was held at the University of Venda, Nkosi used the vibrancy and colourfulness of Venda as inspiration for his design. “When I was designing the poster, the only thing on my mind was making sure that I put something together that was related to Venda,” he explained. In addition, the theme for the Entrepreneurship Week was ‘Move to Market’, and Nkosi asserts that he tried to integrate the theme with Venda, and this is how the design came about.

The outcome of the competition and future plans

Although Nkosi did not win the competition, he did receive a cash prize for being among the top three. Furthermore, given his accomplishment, Nkosi would like to take part in many more design competitions moving forward. “Now that I have realised that I have the potential to win, I think I can take this as a career path in the future,” he said. Nkosi is also looking at merging his love of teaching with his newfound love for design. “I’m going to try and find the connection between design and education, because I really love to teach, so I could perhaps become a design teacher,” Nkosi expressed

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.
