Mental health awareness
The UFS joined the global community in commemorating World Mental Health Day.
“This is not a conversation that should wait until people have taken their own lives or have been diagnosed,” said Tshepang Mahlatsi, Founder of Next Chapter, a student organisation that advocates for mental health. In commemoration of World Mental Health Day, the organisation hosted a dialogue around this year’s theme of Mental Health Promotion and Suicide Prevention on 10 October 2019.

Mahlatsi further said: “The conversation around mental health is not one that should be reserved for September or October when we commemorate suicide prevention and World Mental Health Day. We should build a culture and tradition of having and normalising these conversations. This notion becomes highly relevant at institutions of higher learning where most students are affected by various factors, such as finances and academic anxiety.”

Dealing with the dilemma

This open discussion took place on the Bloemfontein Campus between students and a panel comprising Dr Ntswaki Setlaba and Dr Melissa Barnaschone.

Dr Setlaba, a consultant psychiatrist at Pelonomi Tertiary Hospital, said one of the symptoms of major depressive disorder is suicide. She highly recommends that early detection of depression is essential in order to prevent it escalating to a loss of more lives.

Director of the Office for Student Counselling and Development, Dr Barnaschone, supported the concept of early detection, citing that there are plans put in place to support students, such as workshops and the Student Mental Health Toolkit.

Medicine of the mind

Dr Fanie Meyer, a private psychiatrist based in Bloemfontein, described to staff members the effects of depression and anxiety on the brain. He presented a talk titled: Pain vs Depression: ‘The chicken or the egg?’ which was hosted by the Organisational Development and Employee Wellness division in collaboration with the Faculty of Health Sciences.

He also stressed the importance of early detection. “If you leave your pain running for 10 years, it will get worse. The same goes for anxiety,” said Dr Meyer. 

According to Burneline Kaars, Head of the Division, they are committed to changing attitudes about mental health and reducing the stigma experienced by those who live with it. “The focus is on educating staff about mental illness and empowering them to take action and promote mental wellbeing while it is still early.”  

Recognising the early symptoms of a mental disorder is an essential part of tackling the pandemic. Having the mental health conversation throughout the year instead of in September and October ought to further this agenda.

UFS researcher engineers metal surfaces
2015-03-03

Shaun Cronjé, a PhD student, in a surface characterisation laboratory at the UFS.

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
