  1. 6. Underlying mechanisms behind nitrous oxide emissions in oilseed radish, Raphanus sativus var. oleiformis, and Phacelia tanacetifolia

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Annika Swensson Källén; [2023]
    Nyckelord :nitrous oxide; glucosinolates; greenhouse gases; oilseed radish; Phacelia tanacetifolia; cover crops; labile C;

    Sammanfattning : Greenhouse gases are a driving force of climate change and the annual greenhouse gas emissions were higher between 2010-2019 than any other time in human history (Skea et. al. 2022). LÄS MER

  3. 7. Effects of Forest Ditch Cleaning on Surface Water Quality

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Emeli Arvidsson; [2023]
    Nyckelord :Ditch cleaning; forest clear-cut; water quality; water chemistry;

    Sammanfattning : Ditch cleaning (DC) is recommended by authorities to Swedish landowners to maintain forest productivity after forest harvest by lowering groundwater tables of catchment soils. Knowledge regarding the impact of this practice on surface water quality is limited, and results from previous research vary. LÄS MER

  4. 8. 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. 9. Green Anesthesia : Use of Inhalational Anesthetics and their Effect on our Climate

    M1-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Sabina Karchut; Skylar Wedahl; [2023]
    Nyckelord :MAC – minimum alveolar concentration; GWP – global warming potential; CO2 – carbon dioxide; N2O – nitrous oxide; Low-Flow Anesthesia; sevoflurane; isoflurane; desflurane; FGF – fresh gas flow; MAC – minimum alveolar concentration; GWP – global warming potential; CO2 – koldioxid; N2O - lustgas; Lågflödesanestesi; sevofluran; isofluran; desfluran; FGF – färskgasflöde;

    Sammanfattning : This thesis has, commissioned by Dräger, an international company at the forefront of medical and safety technology, examined how the use of inhalational anesthetics affects the climate and environment. The purpose of this work is to examine how the Swedish healthcare sector currently works with inhalational anesthetics, how different anesthetic machines affect the emissions, as well as alternatives available to reduce anesthetic gases emissions.

  7. 10. Emission of greenhouse gases from constructed wetlands : Nutrient status in relation to methane and nitrous oxide emission

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Christian Lundström; [2022]
    Nyckelord :Constructed wetland; greenhouse gas emission; nutrient status; ebullition; Anlagd våtmark; växthusgasutsläpp; näringsstatus; ebullition;

    Sammanfattning : Agricultural land releases large amounts of nitrogen and phosphorus to water bodies which causes eutrophication. Creating wetlands on agricultural land is one way to prevent this major issue. However, constructed wetlands are a large emission source of greenhouse gases. LÄS MER
