  1. 1. END-OF-LIFE FOR A QUARRY, WHAT IS THE ENVIRONMENTAL IMPACT?

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Kimia Golamian Yosaf Abadi; [2023-06-21]
    Nyckelord :Quarrying; Aggregates; Life cycle; Environmental impact; Restoration; Permit;

    Sammanfattning : Aggregates products are the largest non-energy mining industry in the world, which is the most extracted materials after water. The most prevalent source of aggregates is from quarries, or mines that target the rock itself. LÄS MER

  3. 2. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Linnéa Eriksson; [2023-04-20]
    Nyckelord :soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Sammanfattning : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. LÄS MER

  4. 3. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Sofia Westberg; [2023]
    Nyckelord :Carbon fiber; lignin; cellulose; continuous conversion;

    Sammanfattning : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. LÄS MER

  5. 4. DISTRIBUTED ARTIFICIAL INTELLIGENCE FOR ANOMALY DETECTION IN A MODULAR MANUFACTURING ENVIRONMENT

    Magister-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Hana Hodzic; [2023]
    Nyckelord :;

    Sammanfattning : This thesis investigates anomaly detection and classification in a simulated modular manufacturingenvironment using Machine Learning algorithm Random Forest. This algorithm is tested on a localcomputer and an embedded device, specifically the Raspberry PI. LÄS MER

  7. 5. Economic development in a biodiversity hotspot: what is the jungle worth? : A case study of local understandings of forest use in North Sumatra

    Master-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Sydney Laewen; [2023]
    Nyckelord :Minor Field Study; Sustainable development; Economic development; Natural resource use; Biodiversity; Conservation; Discourse analysis;

    Sammanfattning : Sustainable development as our joint global goal is consensus in the mainstream international arena, in the name of long-term well-being for all living creatures. However economic constraints often limit the choices available to local communities, forcing them to make trade-offs between immediate socioeconomic gains and the long-term sustainability of natural resources.
