Considering the growing importance of energy-efficient building methods timber construction will play an increasingly important role in the future. Today wooden buildings in Slovenia represent just a small percentage of all domestic buildings constructed. Currently the growing trend towards wooden pre-fabricated houses is positive. This study is focused on the reasons pertaining to wooden building...
On September 2–5 took place 3rd Scientific Conference “Woodworking Technique” in Zaleina (Croatia). The organizer of the conference was Department for Process Techniques of Zagreb Unversity in cooperation with Department of Wood Procesing of Czech University of Agriculture in Prague. The leading subject of the conference was widely treated wood processing. Presentations of papers took place in two...
W dniu 25 marca 2010 roku w Instytucie Technologii Drewna w Poznaniu odbyły się warsztaty pt. „Recykling i wykorzystanie drewna poużytkowego i odpadów drzewnych”. W warsztatach wzięli udział eksperci z Polski, Niemiec, Słowacji i Francji. W trakcie dyskusji poruszano problemy związane z odzyskiem, sortowaniem i zagospodarowaniem drewna poużytkowego. Wykłady były prowadzone w języku angielskim.
The Polish Maritime Museum in Gdansk participated in the EU project MACHU aiming at creation of a system of location, making information on European subaqueous maritime cultural heritage available and dissemination of it. 7 EU countries co-operated in the project. The Wood Technology Institute contributed to research on durability of small oak wood samples submerged in the sea. The samples were considered...
Celem pracy było poznanie wpływu właściwości materiałów drzewnych zanieczyszczonych chemicznie na przebieg podstawowych parametrów procesu ich współspalania z węglem kamiennym w urządzeniu kotłowym małej mocy. Dla realizacji założonego celu przygotowano mieszanki paliwowe z trocin tartacznych, poużytkowych odpadów drzewnych i węgla kamiennego. W pracy dokonano oceny przygotowanych stałych paliw wtórnych...
In our study, three phenomenological strength criteria (the von Mises criterion, the Tsai-Wu criterion, and the Ashkenazi criterion) were compared based on experimental data. The goal of this study was to decide which strength theory describes properly the failure of wood under biaxial load. Formerly, a set of biaxial tests was performed on Norway spruce (Picea abies [L.] Karst.) specimens. As a result...
Because of their economic impact most research on wood in Sweden is aimed at our needle-leaved species, i.e. pine and spruce. Sawmills and other industrial enterprises using these conifers are also in vast majority, both in number of employees and number of companies. However, there is a viable industrial branch in Sweden, i.e. furniture companies, dealing with broad-leaved species such as oak, birch,...
Przedstawiono program odbywającego się cyklicznie Sympozjum „Czwartorzędowe sole amoniowe i obszary ich zastosowania w gospodarce”. Kolejna VII Konferencja da możliwość zaprezentowania dokonań pracowników naukowych zajmujących się badaniami czwartorzędowych soli amoniowych z uwzględnieniem cieczy jonowych.
This article presents methods of identification of dynamics characteristics of chain saws. These methods can be successfully used in the process of identification of resonant frequencies and visualisation of ODS of chain saws. Vibration measurements were done using Laser Doppler Vibrometry. Some examples of identification of dynamics characteristics of chain saws and their operational deflection shapes...
This paper presents results of investigations into possibility of using polymethyl methacrylate to reinforce wood degraded by Phellinus pini (Thore) Fr. fungus. It was found that impregnation of wood with the resin causes an increase in mechanical properties. Nevertheless this increase is relatively greater for wood degraded by biological agents than for undamaged wood. The behaviour of wood-resin...
