Countdown to music, art and fun as Kovsie ACT festival approaches
Kovsie students in the process of building their Eco vehicles

The countdown has begun to the Kovsie-ACT music festival that will take place on 17 February 2018 at the Cross Country Fields.

With just a few days left before the main event where students and the community will be wowed by performances from the likes of Prince Kaybee, Jack Parow and Shekinah, students can look forward to the "Social Cohesion" college festivities namely: the West College Project Neon party, East College Graduation party, Central College Yellow party, South College Feballoween party, North College Cowboys and Crooks party, and finally the Kovsie-ACT Fiesta Mexican party.

Each day leading up to the main event, senior on-campus residence students will be working on the building of their various Eco vehicles. Students will be grouped in their designated colleges at the UFS Rag Farm, with the support of the first-years, pending the Eco vehicle race that takes place on Friday 16 February 2018 from 13:00. The ACT office is working towards obtaining sponsors for the overall winners of the race. Their aim is to give the college that wins the race a-once-in-a-lifetime opportunity to attend an official international car race, where they will be represented by their residence committees. The following race criteria apply: 

Race criteria:

Drag race

Fastest time taken to cover distance wins

Slalom race

Fastest time taken to complete course minus penalties

Obstacle course

Fastest time taken to complete course wins (Obstacles will be introduced on the day, no preparation)

Three lap-race

No winner, just preparation for final endurance race but drivers must change each lap

Endurance race

Longest distance covered

 

Students will also be working on art projects in the form of a canvas that must be made of waste materials such as plastic, scrap metal and/or sustainable organic materials. The work must be between three and five metres high and two to four metres wide. It should be durable and not perish if it is placed outdoors for a year. It must be accompanied by a manifesto that explains the theme and symbolism of the artwork so that the five colleges can effectively illustrate what is important to them and their community.

First-year students have also been assigned to participate in projects that engage with local secondary schools in the Bloemfontein area. The content of the projects will be directed through a short learning programme that will take place during the course of the year.

The Kovsie ACT team looks forward to the activities at the Rag Farm, and encourages students to attend and take part in their numbers. For more information about Kovsie ACT visit the UFS Rag page or the Ofm official website.

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.
