  1. 1. The paint loss of Callmander’s stained glass windows: An investigation of the prevalence and causes behind the paint loss on Callmander and Svenska Glasmåleri AB’s stained glass windows

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Victor Eisfeldt; [2024-02-06]
    Nyckelord :Grisaille; Stained-glass; Callmander; Vitreous Paint;

    Sammanfattning : This MA-thesis investigates the loss of grisaille paint in the stained-glass windows created by the artist Reinhold Callmander and Svenska Glasmåleri AB, with the aim of understanding the prevalence as well as the reasons behind the issue. Stained glass has historically been in the periphery of conservation. LÄS MER

  3. 2. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ellen Svens; [2024]
    Nyckelord :Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

    Sammanfattning : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.

  4. 3. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Cecilia Zambelli; [2023]
    Nyckelord :;

    Sammanfattning : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  5. 4. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anton Rolseth; [2023]
    Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER

  7. 5. Image analysis of Light Optical Microscopy (LOM) images of metallurgical samples

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :David Håkansson; [2023]
    Nyckelord :;

    Sammanfattning : Processing metals in different ways often requires stringent quality control to ensure the quality of the processed metal. This master's thesis aims to develop methods for evaluating the quality of metals via image analysis rather than inspecting images manually as it traditionally has been done. LÄS MER
