Heaters
Embrace the warmth of safety: Stay cozy with approved quartz heaters such as the Goldair GHQ-100G, keeping our campus secure and snug.

As winter approaches, the University of the Free State (UFS) is expecting increased heater usage. The Department of University Estates is proactively addressing this surge in energy demand caused by colder weather to safeguard our campuses and help mitigate the risk of loadshedding, ensuring uninterrupted operations for our staff and students.

By addressing the surge in energy demand caused by colder weather and promoting energy-efficient practices, UFS aims to play its part in alleviating the strain on the power system and contributing to national efforts to mitigate loadshedding.

With South Africa enjoying a recent break from loadshedding, Nicolaas Esterhuysen, Director of Engineering Services, stresses the importance of wise electricity usage to prevent outages and maintain safety. “During this uninterrupted power supply, it’s crucial to be mindful of our electricity usage, especially regarding heating in winter,” Esterhuysen emphasises. “By adopting energy-efficient practices, we contribute to the university’s energy-efficiency goals and create a safer environment."

In line with promoting energy efficiency, the Office for Occupational Health and Safety (OHS) is rolling out a comprehensive campaign to remove unauthorised heaters, minimising fire risks in residential and office areas.

Thato Block, Deputy Director of OHS, explains: “With the structural fire season approaching, UFS is prioritising campus safety. As colder weather looms, heaters and other warming devices will be in high demand, prompting preemptive action. OHS and the Electrical workshop will commence removing unauthorised heaters from residences and offices starting May 2024.”

Guidelines for heater usage

To ensure compliance and safety, UFS has established specific guidelines for electrical heater usage on its premises. The Standard Operating Procedure (SOP) outlines permissible and prohibited heater types, along with safety measures.

According to the SOP, only quartz heaters meeting specific criteria, such as the Goldair GHQ-100G model, are permitted on campus. These heaters are designated for offices without air conditioning, prioritising energy efficiency and safety. Furthermore, heaters are not permitted in residences due to the presence of centralised heating systems.

Prohibited models like bar, fan and oil heaters are strictly banned due to their high energy consumption and fire risks. Any unauthorised heaters found on campus will be confiscated to prevent electrical circuit overload and ensure emergency power system reliability.

In addition to regulating heater types, the UFS has implemented a stringent purchasing procedure overseen by the Department of University Estates Electrical Engineers. Approval is required before requisitioning heaters, with only quartz heaters meeting purchase criteria. This proactive approach aims to effectively manage electricity consumption, especially during peak demand periods in winter.

Safety precautions

The UFS community is reminded to exercise caution when using heaters, including maintaining a clutter-free environment around the device, and avoiding covering it. It’s also important to ensure adequate distance between the heater and flammable materials, switch off heaters when unattended, and disconnect them from power sources during prolonged periods of non-use.

Commitment to campus safety

The UFS remains committed to prioritising the safety and well-being of its community. Through proactive measures and fostering safety awareness, the university aims to create a secure environment conducive to teaching and learning throughout the year.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
