Stavba a vybrané vlastnosti dřeva paulownie
 Přikryl, Vojtěch
This bachelor thesis deals with the structure and selected properties of wood paulownie. Test sample sets were manufactured from purchased joint boards tests were conducted to determine the following characteristics wood paulownie. The mechanical properties of the wood compressive strength 26.52 MPa and bend strength 39.70 MPa. From the physical the properties of wood were measured density at humidity 0 % 263.39 kg·m−3 and swelling in radial direction 2.78 %, in tangential directions 4.92 % and volumetric 8.75 %. Finaly and natural durability of wood was evaluated. The first part is described the theory of mechanical and physical properties of wood, in the second part the procedure for evaluating the measured values and the results compared with the first is described theoretical part.

Vliv pozice po poloměru kmene na přirozenou trvanlivost dřeva dubu
 Marek, Michal
The Bachelor thesis is focused on the natural durability of oak tree wood and its variability on the tree trunk radius. The durability was defined as a percentual loss of mass after a fungal attack by the white-decay fungus polypore mushroom (Trametes versicolor) in comparison to the original condition. In addition to the durability itself, its dependence on the wood colour was examined. In the theoretical section, the wood durability problems are described as well as its variability and the characteristics of the English brown oak (Quercus robur). The second part of the thesis contains the statistical evaluation of the measured values
