Member of the research programme group, prof.dr Marko Petrič was for the fourth year invited external examiner at the University of Eldoret, Department of Forestry & Wood Science, Eldoret, Kenya. This proves international / world establishment of the research programme group and international recognition of the researchers from University of Ljubljana, Biotechnical faculty, Department of Wood Science & Technology.
B.05 Guest lecturer at an institute/university
COBISS.SI-ID: 2515081Coworkers of the project organized a training school at the Biotechnical Faculty, Department of Wood Science and Technology in the frame of COST Action FP1302 supported by violin maker workshop Atelje Demšar. 17 trainees from 7 European countries guided by international team of teachers from additional 3 countries attended the training school with an aim to learn the state of the art of dendrochronological dating. They worked practically on dating of violins. They learned how dendrochronological dating is performed, who can do reliable dendrochronological analysis, optimal contents of a dendrochronological report and how to interpret the results which are given by an end date. They learned the strengths and limitations of dendrochronology. Participants had opportunity to learn on culture of Slovenia and after the training school transferred the obtained knowledge in their environments – mainly production and restoration workshops, schools, universities, institutes, and museums.

MSc thesis avarded withe Prešern avard from Biotechnical faculty Wood is a natural material, which is now increasingly used for construction purposes. As all wood species are not sufficiently durable, they should be adequately protected. In our study, we used non-durable Norway spruce, and protected it with non-biocidal products. Spruce was impregnated with a suspension of natural wax, and then thermally modified. The thermal modification was carried out at different temperatures 100 °C, 185 °C, 200 °C, 215 °C and 230 °C. This was followed by the impregnation with the natural wax, which was carried out by 2 methods (immersion and vacuum pressure impregnation), at 2 different concentrations (2.5 % and 5 %). We studied how the thermal modification, the manner of impregnation and the concentration of wax affect the uptake of water vapour, the mechanical properties and resistance to fungi. It has been shown that the thermal modification has a greater impact on the mass loss of the samples, and thus the deterioration of the mechanical properties of wood, but has a positive influence on the resistance to fungi. On the uptake of water vapour, both of the concentrations could be slowed down with proper wax treatment, but for better protection it would be preferred to use the 5 % concentration. More important than the use of concentration is the use of impregnation of wood, in which the vacuum pressure proved to be better
