  1. 1. Developing a protocol for 3D-printable bioink from decellularised porcine tissue

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Vendela Sandin; [2024]
    Nyckelord :Scaffold; Extracellular matrix; ECM; Bioink; Bioprinting; Collagen; Pharmaceutical technology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : T-cell administration via a scaffold is a promising tool for treatment of inoperable solid tumours. Traditional scaffold materials lack the complexity of the extracellular matrix (ECM) that cells normally grow in. An alternative is to instead use decellularised ECM (dECM) from biological tissue to create the scaffold. LÄS MER

  3. 2. Can precommercial thinning be used to create more diversity after planting spruce?

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Astrid Bygge; [2024]
    Nyckelord :Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Sammanfattning : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. LÄS MER

  4. 3. Röjningsstrategiers effekt på stubbskottsutveckling och granmedelhöjd i blandbestånd av gran och björk

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Max Lindhe; Jonathan Samuelsson; [2023]
    Nyckelord :röjningsstrategi; stubbskott; björk; gran;

    Sammanfattning : Olika röjningsstrategier förväntas påverka stubbskottsbildning hos röjstubbar av vårtbjörk (Betula Pendula Roth) och glasbjörk (Betula Pubescens Ehrh), men relativt få studier har gjorts på området, varför det finns utrymme för vidare forskning. Det huvudsakliga syftet med den här uppsatsen var att undersöka skillnaderna i stubbsskottsutveckling till följd av olika röjningsstrategier. LÄS MER

  5. 4. Water mapping in Scots pine stands after thinning

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

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

    Sammanfattning : 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. LÄS MER

  7. 5. Mixed Stand vs Monoculture : a Simulation Study Assessing Growth and Profitability of Norway spruce and Birch in Mixtures and Pure Stands

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Babatunde Dosumu; [2022]
    Nyckelord :N.spruce-birch stands; monoculture; thinning treatment; mixed forest;

    Sammanfattning : Picea abies L. Karst (N. spruce) monocultures dominate the forest landscape of southern Sweden due to their suitability for the prevalent site conditions, well established silviculture, and profitability. However, disturbances such as windthrow, bark beetle damage, and Heterobasidion root rot pose a risk to N. LÄS MER
