Tennis team countrys fourth-best
The Kovsies first tennis team is from left Cornelius Rall, Lienke de Kock, Reze Opperman and Arne Nel (captain).
The first tennis team of the University of the Free State (UFS) obtained a respectable fourth place at the Top Guns Club event that finished at Sun City on Monday 19 February 2018.

It was the first time the tournament was held where all the provincial tennis champs competed for the honours as national club champions.

The Kovsie team was represented by Cornelius Rall, Lienke de Kock, Reze Opperman and Arne Nel. Arne a veteran who has played for the first team for six years, led the team. They played as men’s doubles, women’s doubles and mixed doubles with optional rotation at the end of each set.

The round robin matches consisted out of three full short sets. Thus, the first team to four games, by a margin of two would win the set.

Student crown to defend
The Free State students topped their pool with three wins from three encounters.

Victories came against Lapésa Tennis Club of the Northern Cape, Wesbank from Eden and Cradock from Eastern Province, all by 3-0.

It set up an encounter with Camps Bay from the Western Cape in the semi-finals which the Kovsies lost by 1-2.

In the play-off for third and fourth place the students came unstuck against Marks Park Tennis Club from Gauteng Central.

The Kovsies will next be in action from 13 to 16 April 2018 again in Sun City in a university challenge tournament which they have won for the previous two years.

They boast an outstanding record in student competitions, having won the University Sport South Africa (Ussa) the last eight years consecutively.

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.
