The 2021 Kovsie ACT Eco-vehicle race puts students’ sustainable energy and critical thinking skills to the test.

The University of the Free State (UFS) Division of Student Affairs’ (DSA) Director of Student Life, Dr WP Wahl, believes the knowledge and skills that students have gained through participating in the 2021 Eco-vehicle project will position them more optimally in the future world of work. “We are also tremendously grateful for the project funding received from merSETA; without their support, none of this would have been possible,” he remarked.

The Kovsie ACT Eco-vehicle race, in conjunction with the overall programme, was established to encourage students to learn more about the technology and logic behind sustainable energy sources and how this can influence the future global society.

This year’s events witnessed students competing according to their UFS residence teams, with Sonnedou, Legatum, Kestell (SonLeTell); Soetdoring, Beyers Naude, Arista (Soetbeyrista); and Roosmaryn, Kagiso, Karee (Kar-is-myn) ending in first, second, and third place respectively, obtaining the highest scores for the races they competed in.

Anton Calitz, Electrical Engineer in University Estates who was the announcer on the day, described the event as one that exceeded his wildest expectations. “From a sustainable energy point of view, the eco-vehicle race results really turned the tables, with lower energy usage per lap being successfully recorded – as anticipated,” he further added.

Andre van Wyk, Client Liaison Officer of merSETA (Manufacturing, Engineering and Related Services Seta) for the Free State and Northern Cape – as one of the sponsors of the innovative programme – extended warm congratulations to the UFS for hosting an outstanding event. He further applauded the university for its resourcefulness in virtually adding electronic media broadcasts to extend the event to the entire UFS community.

“The Kovsie ACT Eco-vehicle programme was eye-opening and exposed me to the broad field of electronics. It definitely came as a challenge – one I had not anticipated on that level, because at times I couldn’t even see what all the building was leading to, but I just had to put my mind and hands to work – it pushed me to think critically and creatively. I was honoured to have been part of this entire experience and I’m grateful to Anton and his team, as well as the Kovsie ACT office, for being a constant support structure throughout the process, as it was not easy.” 

These were the humble words of Sinegugu Sibisi, a University of the Free State (UFS) student who was part of the 2021 Kovsie ACT Eco-vehicle race, where sustainable energy was at the order of the day.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
