Louzanne Coetzee and her guide Estean Badenhorst won the silver medal in the 1 500 m in a new African time at the Paralympics in Tokyo on Monday.

It’s been eight years of waiting, but Louzanne Coetzee will finally hang a medal around her neck, and this on the biggest sporting stage in the world.

Coetzee won the silver medal in the 1 500 m women’s T11 final at the Paralympics in Tokyo on Monday (30 August 2021) morning. In the process, she and her guide, Estean Badenhorst, set a new African record (4:40.96).

They are both former University of the Free State (UFS) students, and Coetzee is a resident on the Bloemfontein Campus. 

“I have been competing for eight years and this is my first medal. I’m just overwhelmed. I couldn’t have asked for a better race, a better guide, and better preparation. I’m just very thankful for how everything went down,” Coetzee said.
The race took place at 32 degrees with a humidity percentage of 70 plus. Coetzee’s time was only 2.04 seconds off the previous world record. 

She has had a stunning Games so far. In Sunday’s heat, she improved her personal best from 4:51.65 to 4:49.24 and ran another eight seconds quicker on Monday.

It was also a personal triumph for Coetzee, who experienced the disappointment of being disqualified five years ago at the Rio Games, after a ruling that her guide had stepped in front of her. 

Prof Francis Petersen, UFS Rector and Vice-Chancellor, saluted Coetzee. “We are tremendously proud of what she has achieved throughout her athletics career. She has represented the country numerous times at international sport events and winning a silver medal and setting a new African record is the culmination of hard work and exceptional endurance.” 

“The entire university community was rooting for her; she has done us and her country extremely proud,” Prof Petersen said.

Coetzee still has the T12 marathon on Sunday on her schedule.

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.”
