Film and Visual Media
Johanet Kriel-De Klerk, Chris Vorster, and Martin Rossouw in the auditorium at the Visual Hub, where a lot of time is spent watching and analysing films.

Three years ago, an oblong yellowish-green building arose between Pellies Park and the Beyers Naudé male residence, housing state-of-the art filming, editing, and viewing facilities, and sporting the promising name ‘Visual Hub’ on its exterior.  With this, an exciting interdisciplinary honours degree in Film and Visual Media was introduced.

While the interior and facilities still provide a brand-new impression, lecturers reflect that they’ve come a long way over this period, finding a delicate balance between practical and academic components. 

Not traditional “film school”

“This is not ‘film school’,” lecturer Chris Vorster explains. “Although we have an intensive practical component that sees our students producing a short film at the end of their training, our emphasis is on equipping students with a thorough academic knowledge of film history and analysis.”

Only 15 students can be accepted each year. Applicants should have a degree in the Humanities, scoring at least a 65% average in their final year.

Over the course of a year, students are given a viewing list of selected movies, illustrating different aspects of visual storytelling, film development and techniques, but which also relate to the societies that produced them in revealing ways.

Broadening students’ viewing experience

“Most people tend to get stuck in their favourite genre when it comes to watching movies. We considerably broaden students’ viewing experience,” says Vorster. “We give them as wide a base as possible. When they walk out of here, they can go on to specialise in anything from directing to writing film reviews.”

He usually advises students to see the year after completing their degree as a ‘practical year’, doing volunteer work in as many fields of film production as possible to see what they enjoy most, and then work hard to become a specialist in that field.

“The film industry is a tough world. You really need a great amount of talent and drive to make it.” 

LECTURERS’ FAVOURITE FILM GENRES:

Chris Vorster: DRAMA AND THEATRE ARTS

Science fiction crossed with psychological thrillers, and all that shouts, explodes, devours, hits, and disgusts.

Johanet Kriel-De Klerk: HISTORY OF ART AND IMAGE STUDIES

Indie (independent) films, as they strike a good balance between profound art and everyday entertainment.

Debeer Cloete: DRAMA AND THEATRE ARTS

Science fiction. A great favourite is Steven Spielberg’s A.I. Artificial Intelligence [2001]. Spielberg was asked by Stanley Kubrick’s widow to direct this film after Kubrick’s death in 1999. It stays true to Spielberg’s own aesthetic approach while incorporating Kubrick’s approach to cinematography and fragmented narratives.  

Martin Rossouw: HISTORY OF ART AND IMAGE STUDIES

So-called boring philosophical art films, such as those of Terrence Malick.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
