Two University of the Free State (UFS) students, Keafon Jumbam (PhD) and Chantelle van der Bijl (master’s), emerged victorious at the annual institutional Three-Minute Thesis (3MT) competition held on the Bloemfontein Campus on Friday, 23 August 2019.

The 3MT is a research-communication competition which was developed by the University of Queensland (UQ), whereby PhD students are given three minutes to present a compelling oration on their thesis and its significance. 

Winning students

Jumbam, who is a student in the Faculty of Natural and Agricultural Sciences, cleaned the table in the PhD category, which had six contestants from various faculties. She walked away with a cash prize of R14 000.
She presented a thesis titled: Social, ecological and personality factors influencing bat-eared fox foraging behaviour.
Asked about the secret to her victory, Jumbam said: “You must ensure that you publish your work, because that gives a person a competitive edge, globally.”
In the Master’s Category, Chantelle van der Bijl grabbed the first spot, beating four other contestants in this category, winning an amount of R10 000.  Her thesis title was: Doctor Mothers: Infant feeding intentions and behaviours.
“I am excited to have won this. I am very grateful for the support I got from my family and faculty staff,” said Van der Bijl.

Idea behind the 3MT

The 3MT challenges students to consolidate their ideas and research discoveries in order to be presented concisely to a non-specialist audience. The 3MT was designed to develop skills that will give students an important career advantage once they complete their studies. 
The competition was originally reserved for PhD students, but the UFS Postgraduate School decided to include master’s students so as to prepare them in case they wanted to do their PhDs after their studies. 
The UFS winner in the Master’s Category (Van der Bijl) will not represent the university in the national final 3MT competition on 25 October 2019, but the 1st runner-up in the PhD category (Lourens Strauss) – as per the rules of the competition.

Nothing but research for better future
Giving a word of encouragement to the contestants on the importance of research, the Senior Director for Research Development, Dr Glen Taylor, said: “When our generation of practitioners and leaders (students) engage in research with its deliberate process and requirements for critical thinking skills, they become better students and are best prepared for the challenges and opportunities of the future. Research is an opportunity to make a difference; it is open to everyone and thrives on a diversity of approaches and perspectives.”

Taylor said universities have to be vital sources of new knowledge and innovative thinking, providers of skilled personnel, attractors of international talent and business investment into a region, agents of social justice and mobility, and contributors to social and cultural vitality.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
