  1. 1. ANALYS OCH IDENTIFIERING AV BEKÄMPNINGSMEDEL I HISTORISKA TEXTILIER

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Stina Johansson; [2023-06-15]
    Nyckelord :XRF-analysis; FTIR-analysis; Pesticide Identification; Historical Textiles;

    Sammanfattning : This essay will investigate the risks associated with pesticide contamination in textile collections and how information about pesticide content can be found. Uniforms from the collection of the now closed Gothenburg military museum was analysed using Dosa test strips for chloride content, XRF-analysis and ATR-FTIR analysis. LÄS MER

  3. 2. Framtagande av mätmetod för koncentration av fixativ i bakvatten : Undersökning om FTIR lämpar sig som analysmetod med processvatten för en mjukpapperstillverkning

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Laura Paet; [2023]
    Nyckelord :bakvatten; fixativ; ATR-FTIR; koncentration; mjukpapper;

    Sammanfattning : Rexcell Tissue & Airlaid AB is a producer of paper products such as coloured tissue, where it is important to manufacture a product that does not release any colour during usage. To prevent colour bleeding, a fixative is added during the paper dyeing process. LÄS MER

  4. 3. TILLSTÅNDSBEDÖMNINGAR En metodutveckling med sidenfragment från Birka som utgångspunkt

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Gabrielle Weststeyn; [2022-07-05]
    Nyckelord :archaeological textile conservation; condition assessment; decision-making in collection management; Micro Reflectance Transformation Imaging micro-RTI ; statement of significance;

    Sammanfattning : Despite being an indispensable assessment tool and an ethical obligation in the conservation of cultural heritage, traditional condition assessments encompass several shortcomings that reduce their ability to act as substantiated and unambiguous support for decision-making related to interventive and preventive conservation treatments. Integrating opposing theories in the conservation of cultural heritage generates a method that intends to resolve these shortcomings. LÄS MER

  5. 4. SILKE OCH MIKROORGANISMER En kvalitativ studie av bakterie- och mögelangrepp på siden

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Henny von Schantz; [2022-07-05]
    Nyckelord :biodeterioration; cleaning; conservation; historical silk; textile analysis;

    Sammanfattning : In this thesis, bacteria and mold infestation of silk artefacts are investigated through a literature review, a survey sent out to textile conservators, an interview with a mycologist, and an examination of a mold infested robe used as a case study. The robe was examined using methods, including ATR-FTIR, found in scientific literature and methods, including light microscopy, retrieved from the conservators’ recommendations in the survey.

  7. 5. Performance Analysis of Environmentally Adaptable Grease in Large open gears

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Victor Ogunmoye; [2022]
    Nyckelord :Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

    Sammanfattning : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. LÄS MER
