Dr Tronél Hellberg, UFS alumna, completed her PhD in Music from the OSM in 2018.
The COVID-19 pandemic and subsequent lockdown has posed many challenges. Not only has it distrupted our normal way of life it but has created a ‘new normal.’ Even in these trying times, alumni from the University of the Free State (UFS) have adjusted to the new normal by going above and beyond to make it as normal as possible.
One of these is Dr Tronél Hellberg, an alumna from the
Odeion School of Music at the UFS, who has supported Grade 12 learners by presenting free online prescribed music theory classes. The classes are beneficial for learners following the CAPS or IEB curriculum. “I trust the online videos will assist learners and teachers to get through this challenging Grade 12 year,” says Dr Hellberg. She has
recorded more than 38 live videos on her
G-Sential Theory of Music Facebook page.
The recordings are accessible to Grade 12 learners and their teachers at no cost. Dr Hellberg established the
G-Sential Theory of Music in 2007 and has since published 20 theory of music books.
Apart from assisting in teaching, one of her main objectives is to reach less fortunate learners who do not have access to music teachers. “Grade 12 music literacy requires an accumulative understanding of theory of music,” she says. With her initiative she also aims to “fill any gaps” to solidify knowledge and information which might still be unclear.
Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.
Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.
The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.
It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.
The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.
Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”
“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.
The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.
“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.
And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
