  1. 1. A study on the effects of mercury in the environment: A focus on atmospheric contributions

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jonna Petersson; [2023-06-22]
    Nyckelord :Mercury; deposition; transformation; remediation; ecosystem impact; human health;

    Sammanfattning : Mercury is a metal that can transform between different forms in both the atmosphere and in ecosystems. The transformation as well as properties of the different mercury compounds affect when, how and where the effects will emerge. LÄS MER

  3. 2. Chariots of the Atlantic Warriors - A Comparative Study of Chariot Motifs on Scandinavian and Iberian Rock Art

    Master-uppsats,

    Författare :Hannes Grahn; [2023-03-17]
    Nyckelord :Bronze Age; Rock art; Chariots; Scandinavia; Iberia; Long-distance interaction; Frännarp; Kivik; Villfara; Iberian warrior stele;

    Sammanfattning : During the last two decades, ideas of long-distance interaction between cultures has gained an increased amount of attention in the field of Bronze Age research. Previous research has shown that such a long-distance interaction, connected to the trade of metal and amber, may have existed between Scandinavia and Iberia, facilitated by a group of seafaring warrior-traders, with a shared identity, set of values and cosmology.

  4. 3. Analys av värmedistribution hos en kabelsko vid drift : Med hjälp av finite element analysis

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Kachin Khamrangsee; [2023]
    Nyckelord :comsol; multiphysics;

    Sammanfattning : I detta arbete simulerades pressningsprocessen och värmeflödet hos en kabelsko genom att använda finite element analasis med hjälp av simuleringsprogrammet COMSOL Multiphysics. Syftet med värmeanalysen var för att undersöka om kabelskon får värmefläckar under drift som kan orsaka utmattning av metall. LÄS MER

  5. 4. Characterization of Lamps of IRF Solar Simulator

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Mrunmayee Sonna; [2023]
    Nyckelord :IRF; Solar simulator; Characterization; Thermal simulations; Systema-Thermica; Autodesk Inventor; correlated results;

    Sammanfattning : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. LÄS MER

  7. 5. Varnishing of Fiber-based Closures

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Nisha Sunil David; [2023]
    Nyckelord :Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

    Sammanfattning : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. LÄS MER
