Ergonomics
Martie Bitzer, senior lecturer at the UFS Department of Architecture, says an architect envisions how the user will live in a space and designs accordingly.

“Design is not just what it looks like and feels like. Design is how it works.” – Steve Jobs

Whether at work or at home, scientists have found a way to “comfortably” carry out tasks. According to Martie Bitzer, senior lecturer at the University of the Free State’s Department of Architecture, we all experience discomfort due to the effects of repetitive actions in a day – whether in daily tasks of necessity like washing the dishes or hours spent at work behind a desk or a countertop. “The word ‘ergonomics’ is the key to ease this discomfort!,” she said.

Martie believes that a space needs not only to look beautiful but that it must be practical as well. 

“The specific dimensions of the human body should serve as the designer’s ‘measure’ for the height of your kitchen counter or the angle of your computer screen,” says Martie.

She continues: “In architecture, ergonomics is always the starting point for design. The architect envisions how the user will live in a space and designs accordingly. Ergonomics touches all aspects of a person’s life in a building – from the distance you walk in your kitchen while cooking to the impact of the height of a specific space. It is working at best when you live fluently in a space, unaware of obstacles and challenges. The human body’s capabilities and limitations are at the heart of the responsible designer’s task to improve the quality of life in a building.”

In a world where we are daily more aware of how we engage with our surroundings, good design matters!

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
