The board of the Suid-Afrikaanse Akademie vir Wetenskap en Kuns (SAAWK) recently (22 April) announced the winners of the 2022 prizes. The academy, which was established in 1901, aims to promote the use of Afrikaans in science and the arts.

Havenga Prize for Physical Sciences

Prof Hendrik Swart, NRF B1-rated researcher, SARChI Research Chair in Solid-state Luminescent and Advanced Materials, and Senior Professor in the Department of Physics at the University of the Free State (UFS), received the prestigious Havenga Prize for Physical Sciences.

He says it is an honour to receive this award. “When I look at the list of names that have received the award in the past, I am very humbled and surprised to receive such an award.”

The Havenga Prize, for which candidates are specifically judged on research publications and evidence of their promotion of Afrikaans, has been awarded annually for the past 77 years for original research in the natural sciences or a technical field. 

A collaboration with researchers from the Nelson Mandela University (NMU) on semiconductor materials that improve the efficiency of solar cells, resulted in Prof Japie Engelbrecht (Emeritus Professor, NMU) nominating Prof Swart for this award. He is involved in an NRF collaborative research project with NMU and Linköping University in Sweden.

Prof Swart has played an important role in the acquisition of numerous research devices for analysing the thin layer of phosphor, and the semiconductor devices that can be made from such materials. His research and zeal for his work led to the establishment of the national nano-surface characterisation facility (NNSCF) containing state-of-the-art surface characterisation equipment. 

The PHI Quantes XPS system, for instance, is the first in Africa and one of only 20 in the world. The Quantes XPS system uses X-rays to determine the chemical composition of molecules on the surface of a sample. The system is unique in the sense that it also has an extra X-ray source that can determine the chemical state below the surface, which was not possible in the past. This will help to dictate the position of defects in phosphor materials, which will consequently enable the department to create better phosphor for solid-state lighting as well as solar cell applications.

The most meaningful for him, however, was the production of several well-trained postgraduate students and the generation of high-impact, well-cited scientific publications.

This award, one of several awards he has received during his career, does not signify the end of the road. On the contrary, he is looking forward to improving solar cells by using the phosphor materials they have manufactured, applying it on glass windows doped with phosphors to generate electricity.

NP van Wyk Louw Medal and Alba Bouwer Prize for children's literature

The NP van Wyk Louw Medal was awarded to Prof Hennie van Coller, a researcher who is also affiliated to the UFS. Prof Van Coller, currently an emeritus outstanding professor and research fellow at the university, was a former Head of the UFS Department of Afrikaans and Dutch, German and French, as well as Chairperson of SAAWK. He is known for his impact on the literary world, both locally and internationally, through the quality of his scientific articles and books. 

According to SAAWK, the body awards the NP van Wyk Louw Medal for a person’s creative contributions to the exploitation, organisation, and continuous development of a section of the humanities, significantly contributing to the advancement of the humanities.

Jaco Jacobs, the children’s author of more than 170 books who recently presented the 35th DF Malherbe Memorial Lecture at the UFS, was also awarded for his work. Jacobs, also a UFS alumnus, received the Alba Bouwer Prize for children's literature. The prize, which is awarded every three years, was presented to Jacobs for the book Die boekwinkel tussen die wolke, written during the COVID-19 lockdown period. 

SAAWK will present the awards later this year during two virtual award ceremonies in July.

The launch of a unique conservation project
2011-06-06

 

Our Department of Animal, Wildlife and Grassland Sciences launched a very special pilot project at Woodland Hills Wildlife Estate in Bloemfontein on Friday 03 June 2011, which aims to eventually aid in the conservation and study of one of Africa’s most graceful animals.

The project aims to provide the scientific basis needed for making future decisions in the best interests of the giraffe in the Kgalagadi Transfrontier Park in the Northern Cape and involves collaring and monitoring the behaviour and movement of these animals via GPS.

Based on the public interest in the giraffe and the increased impact of the growing giraffe population on the vegetation in the area, SANParks has been considering the translocation of a number of Kgalagadi giraffe. Due to limited information regarding their adaptation success and potential impact on their new environment, thorough planning and subsequent monitoring of the species is required.

Mr Francois Deacon from our university decided to undertake a PhD study to address the existing challenges. This will be the first study of its kind, undertaken on giraffe.

He says he decided on this project because of his love for animals and conservation. “There are nine sub-species of giraffe and seven of these are already endangered. I want to involve people and make them aware of the plight of the animals and the need for conservation,” he said.

The project kicked off on Friday morning, with a group of students and curious nature-lovers tracking a herd of giraffe at Woodland Hills. The challenge laid in identifying one of the animals which could easily be collared with a GPS device, tranquilising it, and applying the device, without harming the animal.

After a young bull was identified, it was up to Dr Floris Coetzee, a veterinarian, to get close enough to the animal to tranquilise it, and to the group of students to catch it and hold it down. All this was done perfectly and the animal was fitted with its new collars. The collars were designed and made by Mr Martin Haupt, who gained extensive experience in the design of similar collars for other research studies.

Mr Deacon will spend the following two weeks personally monitoring the animal constantly, to ensure that the collars do not cause any discomfort or injury and to determine whether it should be removed or adapted.

It has taken Mr Deacon over a year to plan the collaring process and the associated study. He says the main challenges in the project are financial, since it will cost approximately R500 000 to run over five years.

Thus far he has been supported by Mr Pieter Malan of Woodland Hills, Mr Cas Kempff of Cas Kempff Consulting Engineers and Prof. Frans Swanepoel of the UFS’ Directorate of Research Development, all of whom have been benefactors of the project.
Information gathered from the pilot project will provide the data to assess how to best fit the collar onto the giraffe to ensure that the animal is comfortable and that the collar will last in the wild.  Scientific data will be generated and processed for use by the Woodland Hills Wildlife Estate management.

Should the pilot project be successful, between four and eight giraffe in the Kgalagadi will be tracked using the satellite GPS collars. The GPS collars will enable the constant recording of the location of individual giraffe for up to 2 years. This will allow control and monitoring of the animals in real-time.

The main benefits of the project include, amongst others, improved decision-making, informing tourism development, education and community involvement, improved sustainability and improved cross-border collaboration between South Africa and Botswana.
