Besides being the top medical student at UFS in 2021, Dr Mario Vieira is passionate about food, music and sport, and plays the piano and guitar for leisure.

Dr Mario Vieira, one of the University of the Free State’s (UFS) newest graduates in the MBChB programme, says he is fortunate and blessed to graduate from the Faculty of Health Sciences as the top achiever in the class of 2021. Dr Vieira will graduate at the year-end ceremonies. 

Says Dr Vieira: “Privileged is the first word that comes to mind. Yet, there are so many other emotions and feelings involved. One is relieved that the hard work is over for now, but in the same breath, quite sad that this chapter of one’s life has come to an end. Excitement also comes through, knowing that a new challenge lies ahead.” 

Dr Vieira says being the top achiever is undeniably an unbelievable achievement, but there were many other factors and people who made it possible. His family, especially his parents, were his greatest motivation. Their unconditional love and support have made his success possible. 

Multiple factors led to medicine 

According to Dr Vieira, who wanted to be a pilot when he was growing up, there were multiple factors that led to him eventually study medicine. He says: “My first experience with medicine was at a young age when I lost a good friend of mine to cancer. I believe the seed that was planted began to grow when my brother started studying medicine. 
“In high school I made the decision once I realised I was passionate about people and would love to make a difference in the life of others. I think it was the idea that if one could pass this degree, one would be equipped and capable to change lives on a daily basis. My friends in medicine and the support system in Bloemfontein were also incredibly valuable. When times were tough, we would carry each other through,” says Dr Vieira on graduating in one of the university’s toughest fields.

He is starting his internship on 1 January 2022 at Addington Hospital in Durban. 

Besides medicine, this Bothaville, Free State native is also passionate about food, music and sport. He loves cooking and hopes to retire one day with a small restaurant by the sea – cooking food and putting smiles on people’s faces. He also loves playing piano and the guitar.

His message to other students who might be considering studying medicine is: “Be courageous. You are capable of more than you think. Believe in yourself. Hard work, determination and time management can get you where you want to be.” 

Your courage 

Prof Lynette van der Merwe, who took up her new position as Academic Head in the Division Health Sciences Education, Faculty of Health Sciences on 1 December 2021, congratulated the new cohort of UFS doctors and reminded them of the three Cs in the MBChB programme in 2021 – courage, conviction and compassion.

 “I saw your courage, the way you squared your shoulders and looked personal, academic and financial problems in the eye, and endured. You were brave and strong when it mattered most. and stayed true to yourself despite overwhelming odds. You made good choices although they were hard, you found a way to put one foot in front of the other when you were too tired to even think.”

“In the words of the poet Amanda Gorman, “There is always light, if only we’re brave enough to see it. If only we’re brave enough to be it. May you always carry your light into a dark world.”

New world-class Chemistry facilities at UFS
2011-11-22

 

A world-class research centre was introduced on Friday 18 November 2011 when the new Chemistry building on the Bloemfontein Campus of the University of the Free State (UFS) was officially opened.
The upgrading of the building, which has taken place over a period of five years, is the UFS’s largest single financial investment in a long time. The building itself has been renovated at a cost of R60 million and, together with the new equipment acquired, the total investment exceeds R110 million. The university has provided the major part of this, with valuable contributions from Sasol and the South African Research Foundation (NRF), which each contributed more than R20 million for different facets and projects.
The senior management of Sasol, NECSA (The South African Nuclear Energy Corporation), PETLabs Pharmaceuticals, and visitors from Sweden attended the opening.

Prof. Andreas Roodt, Head of the Department of Chemistry, states the department’s specialist research areas includes X-ray crystallography, electrochemistry, synthesis of new molecules, the development of new methods to determine rare elements, water purification, as well as the measurement of energy and temperatures responsible for phase changes in molecules, the development of agents to detect cancer and other defects in the body, and many more.

“We have top expertise in various fields, with some of the best equipment and currently competing with the best laboratories in the world. We have collaborative agreements with more than twenty national and international chemistry research groups of note.

“Currently we are providing inputs about technical aspects of the acid mine water in Johannesburg and vicinity, as well as the fracking in the Karoo in order to release shale gas.”

New equipment installed during the upgrading action comprises:

  • X-ray diffractometers (R5 million) for crystal research. Crystals with unknown compounds are researched on an X-ray diffractometer, which determines the distances in angstroms (1 angstrom is a ten-billionth of a metre) and corners between atoms, as well as the arrangement of the atoms in the crystal, and the precise composition of the molecules in the crystal.
  • Differential scanning calorimeter (DSC) for thermographic analyses (R4 million). Heat transfer and the accompanying changes, as in volcanoes, and catalytic reactions for new motor petrol are researched. Temperature changes, coupled with the phase switchover of fluid crystals (liquid crystals -watches, TV screens) of solid matter to fluids, are measured.
  • Nuclear-magnetic resonance (NMR: Bruker 600 MHz; R12 million, one of the most advanced systems in Africa). A NMR apparatus is closely linked with the apparatus for magnetic resonance imaging, which is commonly used in hospitals. NMR is also used to determine the structure of unknown compounds, as well as the purity of the sample. Important structural characteristics of molecules can also be identified, which is extremely important if this molecule is to be used as medication, as well as to predict any possible side effects of it.
  • High-performance Computing Centre (HPC, R5 million). The UFS’ HPC consists of approximately 900 computer cores (equal to 900 ordinary personal computers) encapsulated in one compact system handling calculations at a billion-datapoint level It is used to calculate the geometry and spatial arrangements, energy and characteristics of molecules. The bigger the molecule that is worked with, the more powerful the computers must be doing the calculations. Computing chemistry is particularly useful to calculate molecular characteristics in the absence of X-ray crystallographic or other structural information. Some reactions are so quick that the intermediary products cannot be characterised and computing chemistry is of invaluable value in that case.
  • Catalytic and high-pressure equipment (R6 million; some of the most advanced equipment in the world). The pressures reached (in comparison with those in car tyres) are in gases (100 times bigger) and in fluids (1 500 times) in order to study very special reactions. The research is undertaken, some of which are in collaboration with Sasol, to develop new petrol and petrol additives and add value to local chemicals.
  • Reaction speed equipment (Kinetics: R5 million; some of the most advanced equipment in the world). The tempo and reactions can be studied in the ultraviolet, visible and infrared area at millisecond level; if combined with the NMR, up to a microsecond level (one millionth of a second.

Typical reactions are, for example, the human respiratory system, the absorption of agents in the brain, decomposition of nanomaterials and protein, acid and basis polymerisation reactions (shaping of water-bottle plastic) and many more.
