    Author : Michalina Maria Grabowska; [2022]
    Keywords : Scots pine; Pinus sylvestris; drought; thinning; root system; water uptake; heavy water;

    Abstract : Climate change is an ongoing issue in various fields, including forestry. More frequent and severe droughts have been already noted around the world, also in Europe. Visible reduction in available water in forests has adverse consequences such as increased tree mortality, higher vulnerability and smaller growth. READ MORE

  3. 2. Reduction of Set-recovery of Surface densified Scots Pine by Furfuryl Alcohol

    University essay from Luleå tekniska universitet/Träteknik

    Author : Lei Han; [2019]
    Keywords : surface densification; set-recovery; hardness; furfuryl alcohol;

    Abstract :  For wood products such as flooring and worktop, only one surface is normally exposed in their use, and the mechanical properties like hardness and wearing resistance of that surface is then important. Since mechanical properties are strongly related to the density, surface densification, i.e. READ MORE

  4. 3. Finger-jointing of acetylated Scots pine using a conventional MUF resin

    University essay from KTH/Byggnadsmaterial

    Author : Christian Wincrantz; [2018]
    Keywords : Acetylated wood; Scots pine; juvenile wood; finger-jointing; mechanical properties modulus of rupture.;

    Abstract : Acetylation of wood is a modification technique that chemically alters the wood substance and enhances several properties of wood. The basic principle is to impregnate wood with acetic anhydride to react and replace OH-groups with acetyl groups in the wood cell wall. READ MORE

  5. 4. Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood

    University essay from SLU/Dept. of Forest Products

    Author : Victor Fernández-Cano; [2013]
    Keywords : dimensional stability; epoxidised linseed oil; FT-IR spectroscopy; impregnation; leaching; linseed oil; mechanical properties; modified wood; Scots pine sapwood; two-step process;

    Abstract : Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. READ MORE

  6. 5. Planteringsförbandets inverkan på bildningen av kärnved hos tall (Pinus sylvestris L.) : en modellsimulering av planteringsförbandets inverkan?

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Johan Lindström; Erik Persson; [2012]
    Keywords : modellering; extraktivämnen; splintved; krongräns; Pipe modell;

    Abstract : The current state of knowledge indicates that there is more than one factor that initiates heartwood transition. This study supports its hypothesis on the theory that heartwood is formed by a fixed fraction of the annual growthring, 0,5 to 0,8 rings. READ MORE
