UFS researcher publishes the highest-cited Maths paper in the world in 2017
An article by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies received New Hot Paper status from Clarivate Analytics.

An article on Applied Mathematics, published by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies in 2017, was recently named New Hot Paper by Clarivate Analytics.

Hot paper status
Essential Science Indicators (ESI) is a unique and comprehensive compilation of science performance statistics and science trends. Data is based on journal article publication counts and citation data from Clarivate Analytics that enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 1 2000+ journals from around the world, this in-depth analytical tool offers data for ranking papers, scientists, institutions, countries, and journals. 

ESI from Clarivate Analytics is updated every two months. The New Hot Papers, which are papers published in the past two years, are in the top one-tenth of one percent (0.1%) for their field and publication period. Prof Atangana’s paper had the highest cite count in the field of Mathematics. 

His article that received the New Hot Paper status is titled: “The new fractional derivative and application to nonlinear Fisher’s reaction-diffusion equation”.

The concept of fractional differential operators with non-singular kernel has captured the minds of several researchers in the past year due to their wider applicability in almost all fields of science, engineering and technology. The new fractional differential operators have opened new windows to model complex real-world problems that could not be modelled using the Newtonian and the well-known Riemann-Liouville fractional differential operators. 

“These operators are the way forward in modelling real-world problems in all disciplines, as they are able to include into mathematical formulation the effect of memory,” Prof Atangana said.

The Atangana-Baleanu fractional derivative
The professor developed a new fractional differential operator, called the Atangana-Baleanu fractional derivative. This 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.”

New security measures for Rag fundraising
2012-01-25

The University of the Free State will no longer allow first-year students to sell Ritsems or to shake their cans for change at traffic robots in Bloemfontein in an effort to raise funds for Rag Community Service.

This decision follows after an evaluation has been done in 2011 and 2012 concerning the safety risk for students during this type of sales at road crossings.
 
The new security measures have specifically been implemented for this type of sales since last year.
 
The measures included, among others, that students should be obliged to wear brightly coloured safety jackets during sales, continuous supervision of first-year students by senior students to ensure that students keep to the rules of the road, and limiting the sales hours at robots.
 
Through notices in the media, an appeal was made on motorists to keep a lookout for students raising money for Rag Community Service. The measures were implemented and the effects thereof for students’ safety during sales at robots monitored since last year. This follows after a student, Ms Hanje Pistorius, was hit by a reckless driver in 2010 and she subsequently lost her leg as a result of the accident. 
 
Although, from all appearances, the new measures are a positive contribution to protect students even more, the UFS decided to abolish the sales and fund-raising actions at traffic robots. As reckless drivers would not necessarily take notice of the extra measures, the risk to students at robots stay unchanged. 
 
"The UFS sets the safety of its students as first priority and considers it in the best interest of students to not expose first-years to the risk during our Rag programme,” says Mr Rudi Buys, Dean: Student Affairs at the UFS.
 
Night fund-raising and the selling of Ritsem in the city’s suburbs will, however, continue. 
 
Although the UFS do not expect the new measures to be detrimental to fund-raising efforts, Rag Community Service currently considers new supporting proposals for the raising of funds for community projects in order to address any possible reduction in funds. 
 
Mr Buys also has an agreement with Ms Pistorius to assist Rag Community Services in the planning of new projects.
 
The Night fund-raising in suburbs will take place on Tuesday 24 January and Thursday 26 January and the UFS calls on residents to assist students and help them in the important task at hand.
 
Three Rag processions will take place on Saturday 28 January 2012. At 10:00 two Rag procession will be leave for Heidedal and Mangaung, where the Kovsie Rag Community Service will hand out food parcels.
 
The main Rag Procession will leave the UFS at 18:00 and will move towards the Old Greys sports ground for the Rag concert with Die Heuwels Fantasties and DJ Black Coffee.
