Architectural excellence celebrated at recent Sophia Gray lecture
Prof ‘Ora Joubert, a leading architect and academic, delivered the 30th Sophia Gray Memorial Lecture at the UFS.

A jolly kink, creative, aesthetically sensible, a dream house, welcoming, true colours, bright lights – these are some of the terms one can use to describe the work of Prof ‘Ora Joubert, leading architect, academic and former head of the UFS Department of Architecture.

A journey through time and space

She is also the 30th laureate to deliver the recent Sophia Gray Memorial Lecture on the Bloemfontein Campus of the University of the Free State (UFS). The lecture was titled: La Promenade Architecturale – A journey through time and space. “The title refers to the revelatory experience of an observer who wanders on a pathway in and through architectural spaces,” said Jan Ras, lecturer in the Department of Architecture and organiser of the event. 
“As the observer tours the architectural configuration, a sequence of composed images, themes and ordering systems are revealed. This gradually unfolds as the observer moves through the spaces,” Ras said.

The lecture, which coincided with an exhibition at the Oliewenhuis Art Museum, is a highlight of the South African architectural community and celebrates outstanding practitioners and academics in architecture.

Besides the numerous design awards she received as practitioner, Prof Joubert’s work has also received critical acclaim internationally in publications from Australia, to Russia and the UK. In 2001 she was cited as one of the most esteemed architects under the age of 40 and her work was included in the 2004 Phaidon Atlas of Contemporary Architecture. She is also a well-respected academic with 34 articles published in a variety of publications.

Recognising the intelligence and ingenuity of design

Prior to the lecture, the department also presented a mini-congress, introducing the new PhD with Design programme. This programme recognises the intelligence and ingenuity of design and is aimed at, among others, younger MArch graduates who wish to explore creative research. The department envisaged that the PhD study might be practice-based for architects who wish to document and research their own work and or design-led for candidates who wish to explore a new creative project. 

Forming part of this week filled with architectural creativity was a fundraising breakfast, with contributions going to the Sophia Gray Bursary Fund. The fund is part of a greater call to alumni and friends to be actively involved in the department’s continuous development and future endeavours towards imagination, care and excellence.

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.
