  1. 1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands

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

    Författare :Richard Engholm; [2024]
    Nyckelord :chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

    Sammanfattning : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. LÄS MER

  3. 2. The importance of bacterial functional diversity for mixotrophic flagellate function

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Simon Wentritt; [2023]
    Nyckelord :Mixotrophs; Functional Diversity; Algae Culturing;

    Sammanfattning : This project examined the role of functional diversity of bacterial prey organisms on a mixotrophic flagellate’s function. The concept of functional diversity and its role for ecosystem functioning is a subject of ongoing research and controversially discussed. Mixotrophy is the combination of different modes of nutrition in one organism. LÄS MER

  4. 3. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Naga Deepika Peddamudium; [2023]
    Nyckelord :Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. LÄS MER

  5. 4. Satsvisa laboratorieförsök för utvärdering av kolkällor i denitrifikation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Lisa Tejde; [2022]
    Nyckelord :external carbon source; biological nitrogen removal; denitrification; chemical oxygen demand COD ; step-feed biological nitrogen removal; ethanol; methanol; Brenntaplus VP1; industrial waste products; denitrification batch activity tests; extern kolkälla; biologisk kväverening; denitrifikation; kemisk syreförbrukning COD ; kaskadkväverening; etanol; metanol; Brenntaplus VP1; industriella restprodukter; satsvisa laboratorieförsök;

    Sammanfattning : I takt med att Uppsala växer behöver kapaciteten för avloppsvattenrening på Kungsängsverket byggas ut. För att möta en framtida ökad belastning bedömer Uppsala Vatten & Avfall AB att en kolkälla kommer behöva tillsättas i den biologiska kvävereningen för att effektivisera den heterotrofa denitrifikationen på Kungsängsverket, som idag sker utan tillsats av kolkälla.

  7. 5. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Juliane Glinski; [2022]
    Nyckelord :sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

    Sammanfattning : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. LÄS MER
