  1. 6. A geoarchaeological study on two Norwegian boat graves : Soil analysis and an attempt of forensic work strategy and thinking in the interpretation of the results

    Master-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

    Författare :Stefano Vilardi; [2019]
    Nyckelord :Geoarchaeology; forensic approach; Geochemistry; boat graves;

    Sammanfattning : The following paper is the final thesis of two years long experimental work conducted on two different collections of soil samples coming from two different Norwegian archaeological sites. In particular, the first collection of soil samples comes from an identified boat grave from the Viking Age (eg Sykehus area Kristiansand County, Vest-Agder). LÄS MER

  2. 7. Utökad nytta av befintligt energilager

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Victor Eklund; [2019]
    Nyckelord :Energilager; Batterilager; Elnät;

    Sammanfattning : The electrical grid is facing a modernization due to installations of intermittent energy production from wind and solar energy. Energy storage fulfills an important role in this modernization, with potential to store overproduced electricity and use it at a later time. LÄS MER

  3. 8. Adsorption of lysozyme on Silica Surfaces and Specific ion effects

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Guillem Onyos de Plandolit Ruiz; [2019]
    Nyckelord :Ellipsometry; mesoporous silica nanoparticles; surfaces; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : Biomedical application of nanoparticles is largely associated to their fate in biological media which, in fact, is related to their surface properties. Surface functionalitzation plays a key role in determining biodegradation, cytotoxicity and biodistribution through interactions which may be meditated by the macromolecules occurring in biological media.

  4. 9. Bioactivity testing of dental materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Alexander Eriksson; [2019]
    Nyckelord :Bioactivity; bioactive glass; soaking experiment;

    Sammanfattning :  Ever since Hench et al. first discovered bioactive glass in 1969, extensive interest was created because of the materials ability to chemically bond with living tissue. In this project the bioactivity of three different compositions of the bioactive glass Na2O-CaO-SiO2 have been studied. LÄS MER

  5. 10. Occurrence and fate of organic micropollutants (OMPs) in Lake Mälaren

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Anna-Lena Rehrl; [2019]
    Nyckelord :multi-residue method; UPLC-MS MS; SPE; organic micropollutants; surface water;

    Sammanfattning : The main objective of this study is to investigate the occurrence and fate of organic micropollutants (OMPs) in surface water in Lake Mälaren over one year, including their seasonal variations, correlations between compounds, spatial and vertical distribution. The water samples were enriched with solid phase extraction (SPE) and subsequently analyzed by ultra-high pressure liq-uid chromatography tandem mass spectrometry (UPLC-MS/MS). LÄS MER
