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.”

Students translate documents for the aged
2007-11-08

 

As part of practical module in translation, third-year students in Translation Studies at the University of the Free State (UFS) translated a document for a group of aged people. The document is a guide for luncheon clubs of Age-in-Action, a non-governmental organisation working amongst the aged. The document contains information on how the aged can organise the group and the services they can render in the community. The document was translated into Afrikaans and Sesotho with the help of a group in Heidedal and Mangaung, respectively. As part of their course, the students had to meet with the management of Age-in-Action to find out more about the aim of the document. After that, they visited the groups in the community twice to gain information that would ensure that the documents fulfil the needs of the groups. The students attended to matters such as the type of language used by the groups, what the groups do with the document and the layout requirements of the groups, e.g. a larger font. The module in translation studies is presented as a community service-learning module, which means that students learn while rendering service in a community. They have the advantage of learning in a real-life situation and the community has the advantage of receiving a service. The aim is to develop knowledge which is to the advantage of the community. On the photo the translated document is handed to the leaders of the luncheon clubs. From the left, are: Ms Melita Pietersen (luncheon club leader), me. Karma Harvey (third-year student in Language Practice at the UFS), Ms Susan van Eck (luncheon club leader), and Ms Catherine van Rooyen (luncheon club leader).
