Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health, is a finalist in two categories of this year’s NSTF-South32 Awards. Dr Edward C Netherlands, Senior Lecturer in the UFS Department of Zoology and Entomology, is also in the running for his first NSTF-South32 Award.

Dr Michael Pienaar, Senior Lecturer and Specialist in the University of the Free State (UFS) Department of Paediatrics and Child Health, is a finalist in two categories of the 2023 NSTF-South32 Awards, popularly known as the ‘Science Oscars’ of South Africa.

Dr Pienaar, who has been working in paediatric critical care since 2019 and sees the care of critically ill children as his mission and calling in life, has been named a finalist in the TW Kambule-NSTF Award: Emerging Researcher and the NSTF-SAMRC Clinician-Scientist Award categories.

Another UFS staff member, Dr Edward C Netherlands, Senior Lecturer in the Department of Zoology and Entomology, is also a finalist in the TW Kambule-NSTF Award: Emerging Researcher category.

The NSTF-SAMRC Clinician-Scientist Award, sponsored by the South African Medical Research Council (SAMRC), is a new award for an outstanding contribution by a clinician-scientist, with a focus on work to enhance life and improve community health. This new category is modelled on the Emerging Researcher category.

‘Validating to have research recognised’

Dr Pienaar says it is humbling to be considered for these awards alongside formidable, accomplished, and innovative clinicians and scientists. “This is all somewhat surreal, as I was not anticipating being shortlisted as a finalist. It is validating to have had my research, which I am committed to, recognised on this platform. I am very grateful to the School of Clinical Medicine and the Faculty of Health Sciences and University of the Free State for nominating me for these awards.”

He was nominated by Dr Claire Armour Barrett, Clinical Research Director and Specialist Physician in the UFS School of Clinical Medicine.

Dr Pienaar says his current research focusses on applied machine learning in paediatric critical care. He has been working on the development of machine learning models that can be used in clinical practice to improve patient care.

“The work leading to these nominations focused on triage and identification of critically ill children in South Africa. Currently, I am working towards machine learning models implemented in point-of-care ultrasonography and mechanical ventilation.

“I am pleased just to be shortlisted for these awards. I think this provides important visibility for my work, which I feel has major long-term implications for clinical practice. I am also very happy to represent the research work being done in the Faculty of Health Sciences and the UFS on this platform.”

On what it will mean to win a ‘Science Oscar’, Dr Pienaar says, “While this would advance my career, I am very aware that all the candidates would be worthy winners. As it is, the opportunity to be a scholar is reward unto itself, and I am very privileged to be able to do the research I do. As ever, I am very grateful to the University and the Faculty of Health Sciences as well as the National Research Foundation for supporting my work.”

‘Honour and privilege’

Dr Netherlands, who was nominated by Prof Corli Witthuhn, former UFS Vice-Rector for Research and Internationalisation, says, “It is a great honour and privilege to represent the UFS.”

His work as a parasitologist and herpetologist involves specialised research in the study of blood parasites. His current research focuses on the diversity, evolution, and ecological implications of blood parasites in herpetofauna (reptiles and amphibians of a particular region).

“Being shortlisted as a finalist for this award will be a humbling achievement in my career, that may lead to new opportunities and new collaborations,” Dr Netherlands says. “Furthermore, being shortlisted provides a sense of validation and affirmation for the effort that has gone into conducting my research.”

The announcement of the winners will take place at the NSTF-South32 Awards Gala Event on 13 July 2023.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
