UFSAfricaWeek -  Sharing a meal to celebrate Africa Day

Since the foundation of the Organisation of African Unity on 25 May 1963, the day has been renowned as Africa Day, celebrated widely across the world and particularly in Africa to signify Africa’s identity and unity.

As a build-up for Africa Day celebrations, the Student Representative Council’s (SRC) executive committee of the International Students Council collectively came up with the ‘Meal in a jar’ initiative. The purpose of this initiative is to reach out to the community, interact and promote unity as a way of celebrating Africa day. It is also to bring to life the sense of integration and inclusion for international students. “From the time one sets foot at the University of the Free State (UFS), the only community most of us will know is the UFS community,” said Andrei Tendai, the SRC International Students Council representative.
 
The international students’ council in collaboration with Elanja Children’s Initiative identified Heide Primary School in Heidedal for this project. Through the ‘Meal in a jar’ initiative, international students will have the opportunity to engage with the broader community outside the institution’s walls in a fun and unique way. Together with volunteers from House Kestell and other partners, the SRC on 24 May 2018 will prepare and share a meal in a jar with 130 learners.

“This project emphasises the efforts by the SRC to denote a significant shift from an attitude of international students’ isolation and exclusion, to an inclusive and open policy that encourages integration and the promotion of the right to equality,” said Tendai.
 
Celebrating Africa day is also about working towards an Africa that relies on the potential of its people, and whose development is people-driven especially for women, youth and children.

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.
