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.

Up to 60% of students do not have enough to eat
2013-11-15

 

15 November 2013

A report of the University of the Free State has revealed the shocking statistics that almost two-thirds of the students at the university don’t have enough money to buy food, and suffer from hunger during terms.

The study, conducted internally by the university’s Department of Nutrition and Dietetics, was a response to a growing international concern that students worldwide were not getting enough to eat. While studies were conducted in the USA and Australia, no similar research has been done in South Africa.

“There have been many studies on the impact of poor nutrition on school kids,” says Dr Louise van den Berg, Senior Lecturer in the Department of Nutrition and Dietetics, “but almost no research on university students. South Africa is, overall, a food-insecure country, and the university wanted to establish how widespread this problem is among our students.”

The reasons given by students invariably referred to a lack of money, as many students were also supporting families. Some students admitted they lacked the knowledge to feed themselves properly, some admitted to borrowing money to buy food, and some even admitted to stealing food to survive.

“This research has confirmed something we have suspected for a long time,” Dr van den Berg states.

A number of students disclosed that they were reluctant to resort to the university feeding scheme, as they were ashamed to admit they did not have money to buy food.

This study is the first of its kind in South Africa, and underlines the fact that tertiary students are particularly vulnerable when it comes to food security. Often a student has to juggle their studies with their role as breadwinner.

A tiny ray of hope to students who find themselves as food insecure, is the No Student Hungry Programme that offers a food bursary to qualifying students.

This programme, initially established by Prof Jonathan Jansen, UFS Vice-Chancellor and Rector, and now managed by Grace Jansen and Karen Buys, offers a small allowance of about R30 per day to hungry students with an average academic achievement of 60% and above. This criterion discourages entitlement thinking and builds a strong sense of responsibility on the part of those who benefit from the food bursary.

Melanie, a second-year Geography and Environmental Management student, as well as a single mother, is a beneficiary of the NSH Programme. “This bursary helps me to get a balanced meal every day. It is one less worry for me. I dream of completing my studies so that I can be independent and provide my son with the life he deserves.”
