  1. 1. Reconstructing Past Climate by Grain Size and Magnetic Susceptibility Analysis of Belgium Loess From the Late Quaternary

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Susanna Åberg; [2022]
    Nyckelord :aeolian dust; Romont; Europe; true loess line; past climate reconstruction; vindtransporterat stoft; Romont; Europa; true loess line; rekonstruktion av tidigare klimat;

    Sammanfattning : Aeolian dust that gets deposited builds up loess sequences that cover 10% of the Earth's continents. Such sequences can be several metres thick with material deposited over thousands of years, and therefore act like archives of past climates. LÄS MER

  3. 2. Late Quaternary Climate Reconstruction Using Rock - Magnetism in Loess on Portelet, Jersey

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elias Hero; [2022]
    Nyckelord :;

    Sammanfattning : Loess is a very fine aeolian sediment that can be used as a proxy for stadial and interstadial glacialperiods. To understand how Earth’s climate have changed and what effects that change have had on theplanet and life on it we can use climate archives. LÄS MER

  4. 3. Omprövning av markavvattningsföretag - när, av vem och hur?

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fastighetsvetenskap

    Författare :Sandra Mattsson; Elin Willyson; [2022]
    Nyckelord :Drainage; joint drainage unit; joint property unit; water enterprise; re-examination; Technology and Engineering;

    Sammanfattning : Drainage units are measures that permanently modify the water conditions of the land. This is done through drainage or dikes to make the soil more suitable for use by removing unwanted water. Drainage units shall fulfill the purpose of permanently increasing the suitability of a property for a specific purpose. LÄS MER

  5. 4. Prioritising biochar application to arable land in Sweden : A spatial multi-criteria analysis

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Fabian Osslund; [2020]
    Nyckelord :Biochar; Spatial multi-criteria analysis; GIS; Agriculture; Soil enhancement; Biochar volume potential;

    Sammanfattning : Biochar, the solid product of thermal conversion of biomass with little or no available air, is acknowledged as a carbon dioxide removal technique and soil enhancer among other applications. Its potential soil enhancing properties consists of increased water and nutrient holding capacities, liming effects and sorption of pollutants. LÄS MER

  7. 5. Fly larvae composting of fibrous food industry waste : impact of pre-treatment

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Robert Almqvist; [2020]
    Nyckelord :fly larvae; composting; BSFL; waste; recycling; larvae;

    Sammanfattning : With increasing population worldwide comes higher demands of food and greater waste generation. Effective ways for safe nutrient recycling and waste treatment are thus needed to minimize the human impact on the environment. LÄS MER
