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!

Plant-strengthening agent a result of joint effort between UFS and German company
2015-07-27

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.

The application of a plant-strengthening agent in the agricultural industry has, until recently, been largely ignored, says Dr Elmarie van der Watt of the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS). The agent was co-developed by researchers at the UFS and a German company.

The product is moving into new markets, such as China, Vietnam, the USA, and Australia.

ComCat® was the result of extensive research by the German company Agraforum AG. Commercialisation was limited initially to Europe, while research was expanded to other parts of the world, with the University of the Free State as the main research centre.  ComCat® is a unique, non-toxic plant strengthening agent derived from wild plants. It enhances plant growth and yield, as well as resistance against abiotic and biotic stress factors.

Dr Van der Watt says that, in nature, plants communicate and interact by means of allelochemicals (the inherent silent tool of self-protection among plants) and other phytochemicals (chemical compounds that occur naturally in plants), as part of their resistance mechanisms towards biotic and abiotic stress conditions.

Most wild-plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent. “Active compounds contained in extracts from wild plants applied to monoculture crops can potentially supply the signal for the latter to activate their dormant resistance mechanisms.” 

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.  A major advantage is that, despite its enhancing effects on root development and yield, it does not induce unwanted early vegetative growth that could jeopardise the final yield, as happened in the past for nitrogen application at an early growth stage. 

Dr Van der Watt says, “Physiological data on the effect of the natural bio-stimulant product on photosynthesis, respiration, and resistance towards biotic stress conditions indicate that it can be regarded as a useful tool to manipulate agricultural crops. Research also showed that the field of application for this natural product is never-ending, and new applications are being investigated every day.”
