Mathematician makes popular contribution to science Prof Atangana
Prof Atangana is the first African under 40 years of age to be selected as African Academic of Science affiliated in Mathematics. He recently delivered his inaugural lecture and is pictured with Eelco Lukas, Director of the Institute for GroundwaterStudies at the UFS (middle) and Prof Hendri Kroukamp, Acting Vice-Rector: Academic
Prof Abdon Atangana, researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), recently delivered his inaugural lecture on the topic: Understanding God’s Nature with Non-Local Operators.

His research interests are methods and applications of partial and ordinary differential equations, fractional differential equations, perturbation methods, asymptotic methods, iterative methods, and groundwater modelling. Prof Atangana is the founder of the fractional calculus with non-local and non-singular kernels popular in applied mathematics today. He has introduced more than 12 mathematical operators, most of which bear his name (such as the Atangana-Baleanu fractional integral).

He stated: “We will not stop until we change the classical view of doing mathematics. Mathematics is not a subject but a tool given to mankind by God to understand nature. One single mathematical operator cannot portray God’s nature accurately. Therefore the Atangana Baleanu was suggested.”

New weapons

Most physical problems can be expressed in terms of mathematical formulations called differential equations. According to him the differential equation’s aim is to analyse, understand, and predict the future of a physical problem. Prof Atangana introduced the Atangana-Baleanu fractional integral. This brought new weapons into applied mathematics to model complex real-world problems more accurately.

Prof Atangana explained: “The Atangana-Baleanu fractional derivative is able to describe real-world problems with different scales, or problems that change their properties during time and space for instance, the spread of cancer, the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers, and many others. This crossover behaviour is observed in many empirical systems.”

Sudden change

The Atangana-Baleanu fractional derivative is also able to describe physical or biological phenomena, such as a heart attack, the physiological progression from life to death, structural failure in an aeroplane, and many other physical occurrences with sudden change with no steady state.

The new differential and integral operators are nowadays in fashion and are being applied with great success in many fields to model complex natural phenomena. It is believed that the future of modelling complex real-world problems relies on these non-local operators.

UFS Rose Ball promises to be an unforgettable experience
2005-09-08

On Saturday 15 of October 2005, the Department of Paediatrics and Child Health at the University of the Free State (UFS) in collaboration with Medi-Clinic, are hosting a Rose Ball in aid of children and babies with serious diseases and special needs.

The Bloemfontein public should get ready for one of the most magnificent events ever held in the city. 

The Rose Ball promises to offer an evening of glamour, elegance and beauty which will make it an unforgettable and unique event.  The Department aims to make the Rose Ball an annual event to which the Bloemfontein public can look forward to with expectation.

“Excellent food and wine, a 35 man symphony orchestra and of course a magical setting awaits those who attend the Rose Ball.  We will do everything possible to make guests feel special, so that they return to the Rose Ball year after year.  In this way, we can ensure an annual income from this event for children and babies who are very ill and need specialised care,” said Prof. André Venter, Head of the Department of Paediatrics and Child Health.

The Department of Paediatrics and Child Health at the UFS is responsible for the tertiary care, that is highly specialised care, of around 1 000 000 children in the Free State, Northern Cape, North-West, Eastern Cape and Lesotho.  Approximately 13 000 out-patients are treated at the Universitas and Pelonomi Hospitals annually.  Children who suffer from cancer, heart disease, neurological disease and endocrinological and gastro-enterological conditions are treated.  The Department is also responsible for children who need intensive care and children with contagious diseases.  In addition, there is a large neonatal unit where prematurely born babies are treated.

The level of health care needed to treat these children and babies, necessitate highly specialised equipment and knowledge.  However, it is not always possible to replace or upgrade equipment, due to the lack of much-needed funds.  That is why a fund was created within the Department to satisfy the need for funds. The Rose Ball promises to eventually give a vital boost to the fund that will go a long way toward providing in the special healthcare needs of these patients.

The Rose Ball is made possible thanks to the support of Medi-Clinic.

“Medi-Clinic is honoured to be involved in this great effort and in this way take hands with the Department of Paediatrics and Child Health at the UFS.  There are so many children with life-threatening diseases today and we cannot afford to be uninvolved in any effort to make life better and easier for these children.  We at Medi-Clinic, as a private sector company, look forward to establishing a long-term commitment with the Department of Paediatrics and Child Health,” said Mr Sakkie van der Merwe, Hospital Manager of Bloemfontein Medi-Clinic.

Only a limited number of tables are still available for the Rose Ball.  Tickets cost R500 per person or R5 000 per table of 10 people. 

Those who are interested can contact Ms Ilse Olivier at 051-4012415 or Ms Adele van Aswegen at 051-4013535 for more information.
