Every year, 98 million male pigs are castrated in Europe and this surgery is usually carried out before the pigs are 14 days old. Castration is proven to be painful for these animals, not just during the course of the surgery itself, but also for several hours or days afterwards.
It is the treatment of this post-operative pain that Fosse has focused on in her thesis. In addition, piglets often experience pain in connection with conditions such as inflamed joints or traumatic injuries.
Fosse has studied the pharmacology of the two painkillers meloxicam and ketoprofen in piglets. She found that the piglets had a better ability to excrete ketoprofen when they were six days old than when they were three weeks old. This may mean that different dosages should be used, according to the age of the pigs being treated.
By means of an inflammatory model, Fosse showed that piglets treated with ketoprofen experienced significantly less pain when pressure was applied to the inflamed area than pigs receiving no treatment. The painkilling effect was evident for up to 24 hours after the treatment had been given. Meloxicam achieved only a low degree of painkilling effect in this model. Using another model, this medicine was also shown to have a low ability to prevent the production of inflammatory mediators in tissue.
The results of this doctorate can make a big difference to the choice of medicine and dosage to be used in the pain therapy of piglets up to a month old.
Veterinary surgeon Torunn Krangnes Fosse presented her doctoral thesis on 24th September 2010 at The Norwegian School of Veterinary Science. The thesis is entitled: ”Pharmacology of meloxicam and ketoprofen in piglets”.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
