  1. 1. X-ray computed tomography to study moisture distribution in wood

    Author : José Couceiro; Lars Hansson; Mike Milota; Luleå tekniska universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

    Abstract : X-ray computed tomography (CT) has been used as an analysing tool for different features in wood research since the beginning of the1980s, but it can also be used to study wood-water interactions in different ways, such as by determining wood moisture content (MC). The determination of wood MC with CT requires two CT images: one at the unknown moisture distribution and a second one at a known reference MC level, usually at oven-dry condition. READ MORE

  2. 2. Conversion of Wood and Non-wood Paper-grade Pulps to Dissolving-grade Pulps

    Author : Viviana Köpcke; Monica Ek; Herbert Sixta; KTH; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära;

    Abstract : Dissolving-grade pulps are commonly used for the production of cellulose derivatives and regenerated cellulose. To obtain products of high quality, these so-called "special" pulps must fulfill certain requirements, such as high cellulose content, low hemicellulose content, a uniform molecular weight distribution and high cellulose reactivity.

  3. 3. Wood fingerprint recognition and detection of thin cracks

    Author : Tobias Pahlberg; Olle Hagman; Matthew Thurley; Michael Felsberg; Luleå tekniska universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

    Abstract : The first part of this thesis deals with recognition of wood fingerprints extracted from timber surfaces. It presents different methods to track sawn wood products through an industrial process using cameras. READ MORE

  4. 4. Small-Scale Fisheries Governance : Broadening Perspectives on Markets, Relationships and Benefits in Seafood Trade

    Author : Elizabeth Drury O'Neill; Beatrice Crona; Maricela de la Torre Castro; Stockholms universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; SAMHÄLLSVETENSKAP; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES; SOCIAL SCIENCES; Sustainability; Social-Ecological System; Value chain approach; Social realm; Gender Roles; Local attributes; Marine ecosystem; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : This licentiate adresses the relative ambiguity surounding benefit flows from small-scale fisheries seafood trade with a specific focus on how they may be impacted by market and social stuctures. Small-scale fishery governenace has previously taken a narrowly approach to sustainability. READ MORE
