  1. 1. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Fanny Otterlin Karlsson; [2024]
    Nyckelord :agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Sammanfattning : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. LÄS MER

  3. 2. Seasonal Variability of Ice Nucleating Particles (INP) in Southern Sweden

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

    Författare :Tamina Kabir; [2023-03-08]
    Nyckelord :;

    Sammanfattning : Cloud ice crystals are formed by ice-nucleating particles (INPs). The micro-physical properties of clouds, precipitation formation and the life cycle of clouds are strongly influenced by the presence or absence of ice. Therefore knowledge of atmospheric INP concentrations is crucial to improve weather forecasting and climate projections. LÄS MER

  4. 3. Parametric investigation of a theoretical organic rankine cycle

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Jim Wernersson; [2023]
    Nyckelord :;

    Sammanfattning : The energy resource waste heat or low-grade thermal energy is available in vast quantities. Tapping into this resource and converting it to electrical energy would not only reduce energy waste but also has the potential to eliminate greenhouse gas emissions. LÄS MER

  5. 4. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :WULLSCHLEGER LÉA; [2023]
    Nyckelord :Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Sammanfattning : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. LÄS MER

  7. 5. En experimentell studie om VVC & KVC-värmepump för att motverka legionella

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Anton Julin Wallén; Arijan Ghassemloi; Marvina Mukamisha; [2023]
    Nyckelord :;

    Sammanfattning : Denna studie har som syfte att främst motverka legionellabakterier i tappvattnet som kan bildas och växa om tappvattnets temperatur ligger inom riskområdet på 20–50 °C. Inandning av legionellabakterier kan leda till pontiacfeber eller den dödliga sjukdomen legionella. LÄS MER
