  1. 1. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joakim Edlund; [2022]
    Nyckelord :Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

    Sammanfattning : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. LÄS MER

  3. 2. Characterization of Metal Powders in Electron Beam Powder Bed Fusion : Regarding particle size distribution of the finished part

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mattias Jerhamre Engström; Saman Sharif Hedås; [2022]
    Nyckelord :;

    Sammanfattning : As the manufacturing industry looks for better ways to create complex parts using sustainable and efficient methods, the additive manufacturing sector is taking a step forward. Additive manufacturing brings with it a large reduction in material used and the complex structures that can be created are not something to overlook. LÄS MER

  4. 3. Grain-Size Analysis of Loess Deposits of the Last Glacial Period, NW France

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Linnéa Rodin Borne; [2021]
    Nyckelord :loess; grain-size; glacial; Weichselian; Primel-Trégastel;

    Sammanfattning : Loess is an unique record of the paleoclimate of the Quaternary. Because it is directly deposited from the atmosphere, it can be used as a proxy for wind speed and circulation patterns. It can also be directly dated using luminescence. LÄS MER

  5. 4. Machine Learning Applied to Reach Classification in a Northern Sweden Catchment

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Mariana dos Santos Toledo Busarello; [2021]
    Nyckelord :machine learning; geomorphology; random forest; channel type;

    Sammanfattning : An accurate fine resolution classification of river systems positively impacts the process of assessment and monitoring of water courses, as stressed by the European Commission’s Water Framework Directive. Being able to attribute classes using remotely obtained data can be advantageous to perform extensive classification of reaches without the use of field work, with some methods also allowing to identify which features best described each of the process domains.

  7. 5. The applicability of agricultural fibres in industrial cleaning cloths : in the aspects of processability and sustainability

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Liv Walker; Karin Essén; [2020]
    Nyckelord :Nonwoven; Industrial cleaning cloth; Agricultural fibres; Bast fibres; Polyester; Single-use; Nonwoven; Industriella rengöringsdukar; Naturliga fibrer; Bastfibrer; Polyester; Engångsartiklar;

    Sammanfattning : This study has its background in the EU directive, the ‘Single-Use Plastics Directive’. The directive was initiated due to the environmental impacts that the oceans suffer due to plastic waste. The directive presents the most common single-use products found as waste in the oceans, including wipes and cloths. LÄS MER
