Louzanne Coetzee ready to take shot at Paralympics title

For some athletes, the postponement of the Paralympics was a big frustration, but for Louzanne Coetzee it was a ‘blessing in disguise’.

According to the former University of the Free State (UFS) student and current Residence Head of Akasia on the UFS Bloemfontein Campus, she was more than happy to get another 12 months to prepare herself to the very best of her ability. She will be in action at the Tokyo Paralympics in the 1 500 m on Sunday (29 August 2021) and Monday (30 August). On 5 September, she will tackle the marathon. It is her second Paralympics.

“This is the most exited I have ever been for an event. It has been so long since I was able to compete on a high level. I think it is a blessing in disguise. It allowed me more time to prepare. I’m in a great state and I cannot wait,” she said.

In the 1 500 m, Coetzee will be guided by Estean Badenhorst. In the marathon she will run next to Claus Kempen, with whom she has completed a couple of marathons before.

“They are both very experienced and I’m fortunate to have such a great team with me. When you are running an event like the 1 500 m, you need to fully trust your guide with his decision making.”

“The main focus is the track item. I won’t put too much pressure on myself in the marathon. The prime goal is to gain experience in the longer distance, because that is where I’ll be shifting in the future,” she explained.

The South African 1 500 m record holder in the T11 classification (totally blind) clocked a personal best time of 4:51.65 in 2019. She is the world record holder in the 5 000 m; however, the item does not feature on the Paralympic programme.

Dr Abdon Atangana cements his research globally by solving fractional calculus problem

2014-12-03

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
