Mathematician makes popular contribution to science Prof Atangana

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.

Researcher shares platform with Nobel Laureate at conference on nanomedicine

Profs. Lodewyk Kock and Robert Bragg from the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS) both presented lectures at the first International Conference on Infectious Diseases and Nanomedicine that was held in Kathmandu, Nepal, late last year.

At the conference, also attended by senior representatives from the International Union of Microbiological Societies (IUMS), Prof. Kock delivered one of the two opening lectures, titled: Introducing New Nanotechnologies to Infectious Diseases (the other opening lecture was presented by Nobel Laureate, Prof. Barry J. Marshal). Prof. Kock also participated in the farewell address.

In two excellent lectures, Prof. Bragg spoke on Bacteriophages as potential treatment option of antibiotic-resistant bacteria, and on Bacterial resistance to quaternary ammonium compounds.

For Prof. Kock this very first conference on infectious diseases and nanomedicine was followed by a very exciting yeast research excursion through the Mount Everest Highway which winds through the villages of the Sherpa tribe.

He describes his journey: “The Mount Everest Highway is a rough road stretching through hills and glacial moraines of unfamiliar altitudes and cold temperatures. Throughout the journey I had to take care of not contracting altitude sickness which causes severe headaches and dizziness.

“The only way of transport is on foot, on long-haired cattle called Yaks, donkeys and by helicopter. After flying by plane from Kathmandu (the capital of Nepal), I landed at Lukla, regarded as the most dangerous airport in the world due to its short elevated runway and mountainous surroundings. From Lukla, the land of the Sherpa, I walked (trekked) with my Sherpa guide and porter (carrier) along the Everest Highway surrounded by various Buddhist Mani scripture stands, other Buddhist representations and many spectacular snow-tipped mountains of more than 6 000 m above sea level. Of these, the majestic mountain called Ama Dablam (6 812 m), the grand 8 516 m high peak of Lhotse and to its left the renowned Mount Everest at 8 848 m in height, caught my attention.

“Dwarfed by these mountain peaks on the horizon, I passed various villages until I eventually reached the beautiful village called Namche Bazar, the heart of the Khumbu region and hometown of the Sherpa. This took three days of up to six hours walking per day, while I spent the nights at the villages of Phakding and Monjo. From there I walked along the Dudh Kosi River which stretches towards Mount Everest, until I reached the high altitude Everest viewpoint – the end of my journey, after which I trekked back to Lukla to return to Kathmandu and South Africa.

“This expedition is the first exploration to determine the presence of yeasts in the Everest region. Results from this excursion will be used in collaborative projects with local universities in Nepal that are interested in yeast research.”
