Be Safe on road
Be safe on the roads: Prevention is better than a hospital ward or coffin.

Safety starts with you, non-compliance ends you. A traffic spike over the Easter holidays does not justify disobeying road rules. The university is counting on all students, both drivers and pedestrians, to continue prioritising safety on the roads.

Don’t be a statistic, take responsibility
The 2018 Preliminary Easter Road Safety Report issued by the Department of Transport, indicated that most accidents were caused by irresponsibility.  “In 2018, human factor contributed 89,5% to crashes as compared to the 74,3% in 2017. The number of jay-walking pedestrians killed on our roads also increased to 38% as compared to 25,2% in 2017,” said Minister of Transport, Blade Nzimande.

The university implores you to play a role in reducing these numbers in 2019.

On driving and cellphones
According to Arrive Alive, the use of communication devices while driving is prohibited. “No person shall drive a vehicle on a public road while holding a cellular or mobile telephone or any other communication device in one or both hands or with any other part of the body, unless such a device is affixed to the vehicle or is part of the fixture in the vehicle.”

Pedestrian duties
Pedestrians are encouraged to practice caution when using sidewalks and while crossing the road. When walking, face oncoming traffic and pay attention to traffic signs so as not to constitute a source of danger to yourself or to traffic.

Safe speed saves lives
A general speed limit of 60 kilometres per hour shall apply to all public roads within urban areas, 100 kilometres per hour on public roads, and 120 kilometres per hour on freeways. Abide by these speed limits, unless stated otherwise by traffic signs.

More tips on drunken driving, wearing seat belts, and other aspects of road safety are easily available on the Arrive Alive website.

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.
