Use less water and save more
Don't think twice about being water-wise

“Lift up the handle as soon as you flush. Don’t use the whole five litres at a go,” says Dr Cindé Greyling, who reckons we could save 25% of the water we flush down the toilet. Dr Greyling, who completed her PhD in Disaster Management at the University of the Free State (UFS), has spent years studying ways to shape the drought dialogue. Her voice is one that deserves our attention as citizens of this province.

Over the past five years the Free State has been experiencing heightened stress levels on reservoirs and dams due to the drought conditions induced by climate change. Since 2013 the issue has been worsening instead of improving.

Feasible water-conservation strategies
Students and staff members are advised to apply the same principle in the bathroom and kitchen alike by not letting the tap run while rinsing coffee cups. You could save a litre or two a day by (depending on how much coffee you drink and the number of cups rinsed) by quitting this bad habit. According to Dr Greyling, litter on campus is a secondary way of wasting water which many are unaware of. Litter blocks the drains and water which could have otherwise been recycled is lost in the process.

What do fellow Kovsies say?
Unamandla Mdlotshana, a third-year Actuarial Science student proposed eco-friendly adjustments that could potentially save litres of water on our campuses. He believes that using bottles to collect drinking water from taps, installing more water dispensers, and introducing hand sanitisers in bathrooms could drastically minimise water usage.

In Tebogo Chabangu’s view, taking shorter showers, turning off the tap while brushing your teeth, and making sure taps are properly closed are some of the ways we could be water-wise. For the Anthropology honours student being water conscious means changing habits on a daily basis.

Join us as we spread the message of reversing the effects of the drought by saving water prior to the Rector’s engagement with students at 11:30 on 08 March 2018 at the Albert Wessels Auditorium on the Bloemfontein campus.

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.”
