Dr Marié Herbst
Dr Marié Herbst received her PhD with specialisation in Design, titled The (S)Pace of Images: establishing a practice of the conscious abstraction of motion. She hopes that the techniques and processes explored in her research will spark creativity in the way other designers approach their work.

“My research has unveiled the exquisite patterns generated by motion in nature and everyday objects – patterns that often evade our awareness as we encounter motion in a fleeting moment. Abstraction plays a pivotal role in unveiling these exquisite yet largely unnoticed patterns that surround us.”

This is the perspective of Dr Marié Herbst, who graduated at the University of the Free State (UFS) in December, receiving her PhD with specialisation in Design, titled The (S)Pace of Images: establishing a practice of the conscious abstraction of motion.

Abstraction, a key component of building design

Dr Herbst says that the abstract art movement has had a profound influence on how designers think about design. “Highly regarded architects such as Le Corbusier and Zaha Hadid identify their practice of creating abstract paintings as the driving force behind their ground-breaking building designs. Abstraction is therefore a key component of building design, although the process of how it is applied has historically not received adequate attention. My research explores the way abstraction enables designers to include design information that is only possible through the process of abstraction. One such aspect is motion. Through the process of tracing and superimposing still images extracted from films, I can integrate them into a single picture that shows the progression of time,” she explains.

She hopes that the techniques and processes explored in her research will ignite creativity in how other designers approach their work. “The concepts and techniques outlined in my research are intended to prompt other designers to reconsider the procedures they employ when crafting spaces,” she states.

In the future, Dr Herbst says, she would like to further explore the ideas sparked by her research, such as determining how design would be affected by recording movement in a three-dimensional environment. “New technologies such as LiDAR make the recording of three-dimensional information much simpler, and it will increasingly become a part of our everyday lives. This is a potentially useful information stream that could be applied to create novel designs,” she says.

‘Practice-based’ versus ‘design-led’ research

Prof Jonathan Noble, Head of the Department of Architecture, says this is the very first PhD from the new creative research programme in architecture that was launched in 2018, where the student has completed a ‘design-led’ enquiry. 

He explains that the new creative programme differentiates between ‘practice-based’ research, closely tied to real-world architecture, where candidates analyse and study their previous work, and ‘design-led’ research, which is led by an entirely new creative exploration that encourage speculation and experimentation. According to him, the latter leads to a creative enquiry, and this body of new work is analysed and written about.

Following Prof Noble, postgraduate research in architecture in South Africa has traditionally centred around architectural theory, cultural history, urban studies, and conservation. Creative research methods, however, have not been as prominent. The Department of Architecture is addressing this by introducing new postgraduate research modes supported by innovative research degrees, marking a departure from the traditional approach in South Africa.

“We believe the programme will have a lasting and significant effect upon our professional degrees, injecting professional creativity and new thinking into the life of the department, and serving as an opportunity to look deeply into design and pedagogic practices. Over time, the programme will strengthen ties with the profession and address the closed mentalities of the so-called ‘academic ivory tower’.”

“In addition to providing emerging young scholars with opportunities, the programme facilitates the documentation of the unique qualities of South African practice and makes an important contribution to future research publication and teaching pedagogy at the UFS and beyond,” he says.

Bloemfontein's quality of tap water compares very favourably with bottled water
2009-08-04

The quality of the drinking water of five suburbs in Bloemfontein is at least as good as or better than bottled water. This is the result of a standard and chemical bacterial analysis done by the University of the Free State’s (UFS) Centre for Environmental Management in collaboration with the Institute for Groundwater Studies (IGS).

Five samples were taken from tap water sources in the suburbs of Universitas, Brandwag, Bain’s Vlei, Langenhoven Park and Bayswater and 15 samples were taken of different brands of still and unflavoured bottled water. The samples were analysed at the laboratory of the IGS, while the interpretation of the analysis was done by the Centre for Environmental Management.

“We wanted to evaluate the difference in quality for human consumption between tap water and that of the different brands of bottled water,” said Prof. Maitland Seaman, Head of the Centre for Environmental Management.

“With the exception of two samples produced by multinational companies at their plants in South Africa, the different brands of bottled water used for the study were produced by South African companies, including a local small-scale Bloemfontein producer,” said Prof. Seaman.

According to the labels, the sources of the water vary from pure spring water, to partial reverse osmosis (as an aid to standardise salt, i.e. mineral, content), to only reverse osmosis (to remove salts). (Reverse osmosis is a process in which water is forced under pressure through a pipe with minute pores through which water passes but no – or very low concentrations of – salts pass.)

According to Prof. Seaman, the analysis revealed some interesting findings, such as:

• It is generally accepted that drinking water should have an acceptable level of salt content, as the body needs salts. Most mineral contents were relatively higher in the tap water samples than the bottled water samples and were very much within the acceptable range of drinkable water quality. One of the bottled samples, however, had a very low mineral content, as the water was produced by reverse osmosis, as stated on the bottle. While reverse osmosis is used by various producers, most producers use it as an aid, not as a single method to remove nearly all the salts. Drinking only such water over a prolonged period may probably have a negative effect on the human physiology.

• The pH values of the tap water samples (8,12–8,40) were found to be slightly higher (slightly alkaline), like in all south-eastern Free State rivers (from where the water is sourced) than the pH of most of the bottled water samples, most of which are sourced and/or treated in other areas. Two brands of bottled water were found to have relatively low pH levels (both 4,5, i.e. acidic) as indicated on their bottles and as confirmed by the IGS analysis. The health implication of this range of pH is not significant.

• The analysis showed differences in the mineral content given on the labels of most of the water bottles compared to that found by IGS analysis. The possibility of seasonal fluctuation in content, depending on various factors, is expected and most of the bottling companies also indicate this on their labels. What was a rather interesting finding was that two pairs of bottled water brands claimed exactly the same mineral content but appeared under different brand names and were also priced differently. In each case, one of the pair was a well-known house brand, and the other obviously the original producer. In one of these paired cases, the house brand stated that the water was spring water, while the other (identical) “original” brand stated that it was spring water treated by reverse osmosis and oxygen-enriched.

• Nitrate (NO3) levels were uniformly low except in one bottled sample, suggesting a low (non-threatening) level of organic pollution in the source water. Otherwise, none of the water showed any sign of pollution.

• The bacterial analysis confirmed the absence of any traces of coliforms or E.coli in any of the samples, as was also indicated by the bottling companies. This is very reassuring. What is not known is how all these waters were sterilised, which could be anything from irradiation to chlorine or ozone treatment.

• The price of the different brands of bottled water, each containing 500 ml of still water, ranged between R3,99 and R8,99, with R5,03 being the average price. A comparison between the least expensive and the most expensive bottles of water indicated no significant difference in quality. In fact, discrepancies were observed in the most expensive bottle in that the amount of Calcium (Ca) claimed to be present in it was found to be significantly different from what the analysis indicated (29,6 mg/l versus 0,92 mg/l). The alkalinity (CaCO3 mg/l) indicated on the bottle was also found to differ considerably (83 mg/l versus 9,4 mg/l). The concentration of Total Dissolved Salts (TDS) was not given on the product.

“The preference for bottled water as compared to Bloemfontein’s tap water from a qualitative perspective as well as the price discrepancy is unjustifiable. The environmental footprint of bottled water is also large. Sourcing, treating, bottling, packaging and transporting, to mention but a few of the steps involved in the processing of bottled water, entail a huge carbon footprint, as well as a large water footprint, because it also requires water for treating and rinsing to process bottled water,” said Prof. Seaman.
