Two from Kovsies win Agricultural Student of the Year competition
The competition was an opportunity to force yourself out of your comfort zone and to benchmark yourself against students from other universities. Chéri-Lynn Steyn is pictured here with Mario van den Heever, winner of the Animal Science category of the competition.

This year, two Kovsies won the Old Mutual and Plaas Media Agricultural Student of the Year titles. Chéri-Lynn  Steyn was named the best Agricultural Economics student, and Mario van den Heever was the best Animal Science student. 

Chéri-Lynn  is currently doing her final year of BScAgric in Animal Science and Agricultural Economics. After obtaining her master’s degree, she would like to write modelling programmes for livestock, either for feeding pens or grazing systems. “This is something which fascinates me,” said Cheri-Lynn.

On obtaining his master’s, Mario (currently a final-year student) would like to follow the entrepreneurial route. After winning the competition, he believes that his chosen study field was the right career for him.

The main objective of the competition was to encourage students to pursue careers in an agricultural field. Students are therefore motivated to critically reflect on the major issues within the agricultural sector.

Strong competition

Students from the agricultural faculties of the University of the Free State, the University of Pretoria, Stellenbosch University, and the University of KwaZulu-Natal participated in the competition. 

Among others, they had to submit an essay of 5 000 words on a prescribed topic. Following this, a semi-final was held at each university during which the students had to present their essays and the best student in each of the subject fields for that particular university was chosen. The students competed in the categories Agricultural Economics, Animal Science, and Crop Production. 

Great opportunity for benchmarking

In Agricultural Economics – the category in which Chéri-Lynn  was named the winner – the topic of land expropriation without compensation was investigated, and the question was put whether South Africa would derive any socio-economic benefit from the proposed expropriation.

In Animal Science – which was won by Mario – students had to investigate the South African meat classification system. The question which was asked was whether the current system could be reformed to meet the needs of modern meat consumers in terms of meat quality and whether an international grading system should be adopted.

The Head of the Department of Agricultural Economics at the UFS, Dr Frikkie Maré, said he was very proud of the students. Both of them are currently research assistants in the department.

“The UFS prepares its students very well for the workplace. There are many opportunities to get exposure in the industry; we have almost every week someone from a well-known company to talk to us as students, or even a course, a congress or a farmer’s day that we have to attend,” said Chéri-Lynn .

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.
