Before the event, he didn’t think it was possible to set two new national track records within 18 hours, but he gained so much confidence after the first win that Danie Breitenbach decided to simply go for it.

With the help of his guide, Oratile Molale, the final-year Law student at the University of the Free State bettered his own South African records in the 800 m (2:05,04) and 1 500 m (4:25.59) in the T11 category (completely blind athletes). This was at the SASAPD National Championships for physically disabled and visually impaired athletes in Stellenbosch. His previous records were set in 2017.

“I struggled with various injuries over a period of two and a half years, during which I never managed to gain my top form. Since January, I was able to train injury-free. I was confident that I could improve on my 800 m record of 2:08,90. Having had such a great first race gave me the confidence to give the 1 500 m record a go the next morning,” Breitenbach (24) said.

With no 800 m event at the Paralympic Games or the World Championships, he is hoping to qualify in the 1 500 m for next year’s Paralympic Games. “I will have to improve on my time, as they are only taking about the top-five in the world. I’m sure I can go quicker with another couple of months of training.”

“I’ve been to a few international events, but these two records will rate among my best achievements. I compete in the 400 m, 800 m, and 1 500 m, but the 800 m is my favourite. I enjoy the balance between speed and endurance.”

Breitenbach was born with limited vision, but at the age of ten became completely blind after suffering a retinal release.

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.”
