  1. 11. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Gabriella Zimmerman; [2023-11-07]
    Nyckelord :plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Sammanfattning : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. LÄS MER

  3. 12. FRÅN VITT TILL GRÖNT, RÖTT ELLER BRUNT: Kan blindering åtgärdas med kunskap vi redan har?

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Annica Drotz; [2023-11-07]
    Nyckelord :blanching; oil paint; bloom; paint layer; accelerated aging; consolidation;

    Sammanfattning : Blanching is a common phenomenon affecting the binding medium within the paint, resulting in an abnormality of the paints light scattering. Multiple studies have confirmed that the change is the result of pore formation within the binding medium caused by humidity or water damage. LÄS MER

  4. 13. Relationship between Fatigue Properties and Surface Treatment of Aluminum Alloy

    H-uppsats,

    Författare :Umair Ali Khan; Soroosh Zahedi; [2023-09-14]
    Nyckelord :Corrosion resistance; Fatigue; Aluminium alloys; HPDC; PMC; Sheet Metal; Anodization Molding; Casting;

    Sammanfattning : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. LÄS MER

  5. 14. The Impact of Global Warming on Wind Power Potential in the Greater Horn of Africa

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Bromwel Apondi; [2023-08-17]
    Nyckelord :Near-surface wind speed; the Greater Horn of Africa; ERA5; Wind power density; CORDEX-Africa;

    Sammanfattning : The wind speed variability and wind power potential in the Greater Horn of Africa is analyzed in this study to fill a knowledge gap regarding if wind power can be used more as a source of energy for the region. This is investigated based on reanalysis data from ERA5, observed wind speeds, CORDEX-Africa regional climate models (RCMs) for future projections and a literature review. LÄS MER

  7. 15. Drivers of sea level variability using neural networks

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Linn Carlstedt; [2023-05-10]
    Nyckelord :;

    Sammanfattning : Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh water into the oceans due to melting of the Earth’s land ice together with thermosteric changes has led to a rise of the global mean sea level with an accelerating rate during the twentieth century.
