Two athletes, both employees of the University of the Free State (UFS), are now giving back to the sport in administrative roles.

Kesa Molotsane and Louzanne Coetzee are making time in their work and training schedules to serve the sports in which they have represented their country – Molotsane in cross-country and Coetzee in the 1 500 m and 800 m T11 category for athletes with a disability.

Coetzee is again heading for the Paralympic Games in Tokyo. She is a nominee for the International Paralympic Committee Athletes’ Council. Six representatives will be chosen at the Paralympics.

Coetzee was recently elected to the South African Sports Confederation and Olympic Committee Athletes’ Commission. She is also an athlete representative of the South African Sports Association for Physically Disabled.

Molotsane was co-opted into the National Executive Committee of University Sport South Africa as an assessor. She is also the new vice-chairperson of the Athletics South Africa Athletes Commission.

“My biggest dream is to enable athletes to dream big, and for their dreams to be recognised. I would like to see them enjoy their sport,” said Molotsane.

“I think I probably missed a lot of opportunities in my career due to a lack of funding, so I don’t want to see anyone face the same situation.”

Molotsane was also recently named as one of two ambassadors for the SPAR Grand Prix Series. 

According to Coetzee, a former member of the Student Representative Council at the UFS, she believes that it is important for a current sportsperson to contribute and give input in their sport. 

“I enjoy leadership, it is perhaps a gift of mine. Serving the sport in that capacity is not something that is too much of an effort or takes too much of my time. I enjoy contributing and to see something move in a direction.”

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.”
