    Sammanfattning : Most of our knowledge about wood production of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) and associated silvicultural guidelines are based on field experiments. LÄS MER

  3. 27. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability

    Författare :Tinh Sjökvist; Åsa Blom; Carsten Mai; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Heartwood; Sapwood; Wood extractives; Moisture content; Paint; Alkyd; Acrylic; Linseed oil; Calcimine paint; Mould; Fungi; Algae; Weathering; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. LÄS MER

  4. 28. Forest Biomass Production Potential and its Implications for Carbon Balance

    Författare :Bishnu Chandra Poudel; Mittuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : An integrated methodological approach is used to analyse the forestbiomass production potential in the Middle Norrland region of Sweden, and itsuse to reduce carbon emissions. Forest biomass production, forest management,biomass harvest, and forest product use are analyzed in a system perspectiveconsidering the entire resource flow chains. LÄS MER

  5. 29. Investigating Consumer Perceptions by applying the Extended Association Pattern Technique : A Study on Wooden Multistory Houses

    Författare :Tobias Schauerte; Anders Baudin; Anders Pehrsson; Udo Mantau; Växjö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Means-End Chain Theory; Means-End Theory; laddering technique; laddering; Association Pattern Technique; end use analysis; wooden multistory houses; timber construction; wood construction; wooden housing; Business and economics; Ekonomi; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : During the past years, the usage of wood as construction material in multistory applications has increased. In Germany and Sweden, various activities have been, and are about to be performed, to accentuate and improve the position of wooden multistory houses. LÄS MER

  7. 30. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industry

    Författare :Henric Svensson; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood leachate; Log yard runoff; Stormwater; Toxicity; Artemia salina; Vibrio fischeri; Constructed wetlands; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. LÄS MER
