  1. 1. Some aspects on strength properties in paper composed of different pulps

    Författare :Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Øyvind Gregersen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; reinforcement; multilayer; stratified; handsheet former; abaca; southern pine; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : For papermakers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are desirable both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging and light-weight building material. LÄS MER

  2. 2. Evaluating thinning practices and assessment methods for improved management in coniferous production forests in southern Sweden

    Författare :Magnus Persson; Johan Bergh; Lauri Mehtätalo; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; thinning; within-stand variation; tree species classification; Scots pine; Norway spruce; Sentinel-2; Heureka; Precision forestry; thinning detection; basal area; Forestry and Wood Technology; Skog och träteknik;

    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. 3. Submerged Landscapes in the Hanö Bay : Early Holocene shoreline displacement and human environments in the southern Baltic Basin

    Författare :Anton Hansson; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; Submerged landscapes; Baltic Sea; Southern Sweden; Geoarchaeology; Mesolithic; Early Holocene; Environmental reconstruction; Shoreline displacement;

    Sammanfattning : During times of lower global sea level, vast areas of the coastal shelf were exposed and converted into ecologically diverse coastal landscapes that wereattractive for human occupation. The landscapes were subsequently flooded during the deglaciation, but well-preserved remains of these landscapes andtheir inhabitants can today be found on the seafloor. LÄS MER

  4. 4. Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits

    Författare :Johannes Edvardsson; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; The Holocene.; Peatland development; Scots pine; Palaeoclimatology; Dendrochronology; Subfossil trees; Raised bog; Palaeohydrology;

    Sammanfattning : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. LÄS MER

  5. 5. Fire history in the hemiboreal and southern boreal zones of southern Sweden during 11000 years : Relationships with past vegetation composition and human activities and implications for biodiversity issues

    Författare :Qiao-Yu Cui; Marie-José Gaillard; Boris Vannière; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fire history; land-use history; biodiversity; charcoal analysis; Landscape Reconstruction Algorithm LRA ; Holocene; Småland; Sweden; Paleoecology; Paleoekologi;

    Sammanfattning : This thesis studies fire history over the last 11 000 years (Holocene) in central Småland, southern Sweden, on the basis of palaeoecological analyses of peat sequences from three small bogs (Notteryd, Stavsåkra and Storasjö). The main objective is to gain insights into the long-term relationships between fire, climate, human-impact, other environmental factors and the history of biodiversity in the study region. LÄS MER
