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

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE

  3. 2. Investigation of Ice Nucleating Particles (INPs) in southern Sweden - With a special focus on their origin, possible connection to meteorological parameters and aerosol properties

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Malin Forsmalm; [2023-06-21]
    Keywords : INPs; DFA; LUCS;

    Abstract : This study investigates if there is a seasonal variability of ice nucleating particle (INP) concentrations. There is also a focus in seeing if there are correlations between meteorological parameters and aerosol properties and the measured INP concentrations. READ MORE

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

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Tamina Kabir; [2023-03-08]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Är mjölkprover en alternativ provtagningsmetod för diagnostik av lentivirus hos små idisslare?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Elin Fogelberg; [2023]
    Keywords : maedi-visna; kaprin artrit encefalit; SRLV; serum; mjölk; pool; frysning; kontrollprogram; ELISA;

    Abstract : Lentivirus hos små idisslare (engelska: small ruminant lentivirus; SRLV) innefattar två olika virus: visna-maedivirus (VMV) och kaprin artrit encefalitvirus (CAEV). Dessa två virus orsakar kroniska infektioner hos små idisslare som slutligen leder till döden. READ MORE

  6. 5. Modeling of the trajectory of ice thrown from a wind turbine

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Elena Rocchi; [2023]
    Keywords : Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

    Abstract : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.
