Some criteria of density in beech saplings were studied in various forest associations (mainly Galio odorati-Fagetum typicum) growing in the submontane region near Zurich (Swiss Central Plateau). The sample plots were established in regeneration gaps resulting from Swiss irregular shelter wood system (Femelschlag). Five sample plots, each 2x2m in 3 transects (a total of 15 plots in each gap, x...

Wood and wood-based materials are widely used in the construction industry world. The sustainable renewable nature of wood is seen as an important advantage contrast to non-renewable resources such aluminum, steel, concrete, plastic. In order protect advantages eliminate / reduce its disadvantages, plywood, particle board, fiber LVL, CLT, plastic composites etc. new engineering products produce...

Beech-forests (Fagus sylvatica L.) represent the natural vegetation cover for the majority of sites in Germany. Although coniferous forests actually dominate, beech is the most important among the deciduous tree-species in Germany, when considering the area and the economics. While the wood of the younger beech normally shows a whitish colour (white beech), the timber of older beech may form co...

Abstract Forest management allows the sustained removal of significant amounts carbon from atmosphere. Within different activities in forest, wood utilisation has most man-made environmental impact which affects balance, is important to know, be able accurately identify its role climate change. This study aims determine footprint logging during based on scenario analysis national default and th...

The test panels obtained from Scots pine (Pinus sylvestris L.) and Eastern beech (Fagus orientalis L.) were initially adjusted to have 8%, 10%, and 12% moisture content in this study. One-component semimatte and two-component water borne varnishes were applied on the surfaces in order to investigate the effect of the type and the moisture content of the wood on the hardness and the gloss values...

209 ABSTRACT: In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. ...

Tannins and their toxic effects against various decay organisms have been interrelated for centuries. As natural products gained more interest, waste from several production fields abundant in tannins has yielded promising components wood preservation. In this work, the main approach was to split condensed into smaller fractions by chemical hydrolysis evaluate suitability beech impregnation. Co...
