  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

  2. 2. Indocyanine-green fluorescence imaging to detect anastomotic insufficiency after esophagectomy

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Love Kildetoft; [2024]
    Nyckelord :Fluorescence; Imaging; Indocyanine-green; ICG; Esophageal cancer; Physics; Photonics; Image Analysis; Blood Perfusion; Anastomotic leakage; Anastomotic insufficiency; Physics and Astronomy;

    Sammanfattning : This research project is concerned with the development of simulation models and image analysis algorithms, as well as instrumentation for characterizing anastomotic leakages after a patient has undergone surgery for esophageal cancer. Anastomotic leakage is a high-incidence complication after esophagectomy, a surgical procedure for esophageal cancer. LÄS MER

  3. 3. Nya metoder för fernissaborttagning – En komparativ studie

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Alica Larsson; [2023-11-08]
    Nyckelord :Oil painting; Varnish removal; Evolon® CR; Tissue-gel composite;

    Sammanfattning : In recent years, new varnish removal methods have emerged in conservation, with two notable approaches: the tissue-gel composite method, involving gel-coated tissue material pressed onto varnished surfaces for simultaneous dissolution and binding, and the use of Evolon® CR textile saturated with solvent. Evolon® CR offers an alternative to gels and tissue-gel composites, aiming to eliminate residue from gel thickening agents and the need for mechanical cleaning, while enabling the use of non-polar solvents in a bound form.

  4. 4. FÖRUNDERSÖKNING AV EN EGYPTISK POLYKROM KISTA Dokumentation, tillståndsbeskrivning och analys

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Ida Kingo; [2023-06-15]
    Nyckelord :consolidation; heritage science; ancient Egypt; polychrome coffin; XRF; FTIR;

    Sammanfattning : On ancient Egyptian polychrome art and mainly on coffins, it was normal practice to apply a thick ground and gesso before painting the wood. Sometimes varnish was also applied. Due to fluctuating levels of relative humidity and temperature, the wood swells and shrinks, causing the layers on top of the wood to become damaged. LÄS MER

  5. 5. Image Segmentation and Object Identification in Cancer Tissue Slides from Fluorescence Microscopy

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Sebastian Eriksson; Fredrik Forsberg; [2023]
    Nyckelord :image analysis; cancer research; fluorescent microscopy; image segmentation; bildanalys; cancerforskning; fluorescensmikroskopi; bildsegmentering;

    Sammanfattning : In cancer research, there is a need to make accurate spatial measurements in multi-layered fluorescence microscopy images. Researchers would like to measure distances in and between biological objects such as nerves and tumours, to investigate questions which includes if nerve distribution in and around tumours can have a prognostic value in cancer diagnostics.
