  1. 1. 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

  3. 2. Guld och gröna skogar : En analys av värdefull ekmiljö i Stockholms län

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Camilla Pakka; [2023]
    Nyckelord :;

    Sammanfattning : Ek (Quercus spp.) är nationellt av stor betydelse för biologisk mångfald, arterna utgör centrala och grundläggande komponenter i lokala ekosystem. Stockholms län är en av Sveriges mest tätbefolkade regioner där en snabb förtätning av urbana miljöer och hög exploateringstakt utgör ett reellt hot mot värdefulla ekmiljöer. LÄS MER

  4. 3. Additive Manufacturing for Volume Production : A case study in supply chain benefits of AM implementation

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Carl-Johan Bjelke; [2023]
    Nyckelord :Additive manufacturing; Industry 4.0; Design for additive manufacturing; Rapid prototyping; Mass customization; Parts consolidation; Supply chain processes; Decentralized manufacturing.;

    Sammanfattning : Additive manufacturing was first introduced in the 80s and has ever since been used as a tool for rapid prototyping. Its flexible manufacturing characteristics makes it optimal for creating complex geometries in one manufacturing process, eliminating assembly time for several individual parts. LÄS MER

  5. 4. Consequences of alternative forest management in riparian buffer zones : a GIS analysis

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

    Författare :Elijah Ourth; [2023]
    Nyckelord :Riparian buffer zones; Continuous cover forestry; CCF; Hyggesfritt; Geographical information system; Ditch network maintenance; Ditch; Stream; Natural channel;

    Sammanfattning : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.

  7. 5. On the road to grid stability - Using batteries in heavy vehicles and charging infrastructure as frequency reserves

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Matilda Kjellström; Caroline Wuttke; [2023]
    Nyckelord :Case Study; Electrification; Frequency regulation; Energy reserve; Battery; Heavy vehicles; Vehicle-to-grid; Technology and Engineering;

    Sammanfattning : Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. LÄS MER
