  1. 1. Jag har snövatten! : En kvalitativ studie om de yngsta barnens meningsskapande under kemiaktiviteten ”Olika ämnens löslighet i vatten”

    Uppsats för yrkesexamina på grundnivå, Karlstads universitet

    Författare :Cecilia Mattsson; [2023]
    Nyckelord :the youngest children; interaction; materials; meaning-making; productive questions; de yngsta barnen; interaktion; material; meningsskapande; produktiva frågor;

    Sammanfattning : The purpose of the study is to contribute with knowledge about the youngest children's meaning-making based on a chemistry content in the activity "Solubility of different substances in water". The study is conducted from a socio-cultural perspective. The study is qualitative and based on the methodological approach Design-based research. LÄS MER

  3. 2. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

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

    Författare :Margot Jeanne Knapen; [2023]
    Nyckelord :Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Sammanfattning : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. LÄS MER

  4. 3. Multifunctional ice and snow repellent coatings for photovoltaic modules

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Gunnar Sandkvist; [2023]
    Nyckelord :sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

    Sammanfattning : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. LÄS MER

  5. 4. Evaluation of the variation in albedo over snow-covered forest in Northern Sweden and Finland

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Klara Hugosson; [2022-05-20]
    Nyckelord :;

    Sammanfattning : The effect of albedo variability induced by meteorological parameters in snow-covered forested areas at local scale is poorly known. Few meteorological stations measure albedo, even though the effect on albedo caused by land use changes is well known. LÄS MER

  7. 5. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Thibault Desjonquères; [2022]
    Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

    Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER
