Lubabalo Dobela
Flyhalf Lubabalo Dobela will be an important cog in the wheel for the Shimlas against the Maties in the semi-final stage of the Varsity Cup. He has been named Player that Rocks twice this year.

The Shimlas (University of the Free State) will go into the semi-final against the unbeaten Maties with confidence, knowing that they can compete against them, said coach Hendro Scholtz.

The Shimlas will travel to Stellenbosch for the Varsity Cup clash on Monday (8 April). They qualified for the play-offs thanks to a 38-14 victory over the University of Johannesburg (UJ) in the final round of the competition on Monday 1 April 2019.

The Free State students lost to the Maties by 59-14 two weeks ago, and although the score reflects a big hiding, the Shimlas stood tall for most of the encounter.

“With 18 minutes remaining, we trailed by only ten points (14-24). We can gain confidence from that. We learned a couple of things about them. We will have to stop their driving mall and be sharp when it comes to our discipline. They will hurt us if we concede penalties,” said Scholtz.

According to him, it is important to get off to a good start. “You often sit with students who have other things to think about apart from rugby, such as upcoming tests, which can hamper their concentration. Against UJ in the wet, it was important to play the conditions right, and I think it made the players concentrate that little bit more.”

The Shimlas won four of their eight group matches and will look back on their defeats against the Pukke and Ixias as matches that they could easily have won on another day.

It is the fifth time in the 12 years of the Varsity Cup that the Shimlas have reached the final-four stage, with one win in 2015 over the Ikeys.

The Shimlas will be without two of their key men among the forwards – the injured flank Janco Cloete and hooker Hanno Snyman.

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.
