  1. 1. Resin composites : Sandwich restorations and curing techniques

    Författare :Anders Lindberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Adaption; Clinical; Degree of conversion; Depth of cure; Flowable; Resin composite; Restorations; SEM; Medicin;

    Sammanfattning : Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing demand for aesthetic restorations. LÄS MER

  4. 3. Resin transfer moulded composite materials : processing, structure, property relationships

    Författare :J. Anders Holmberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.

    Sammanfattning : This thesis treats various aspects of structural polymercomposites in aircraft applications. The mechanical performanceand quality of resin transfer molded (RTM) carbon fiberreinforced epoxy composites is studied. LÄS MER

  7. 5. Resin acids in commercial products and the work environment of Swedish wood pellets production : Analytical methodology, occurrence and exposure

    Författare :Sara Axelsson; Ulrika Nilsson; Kåre Eriksson; Håkan Westberg; Martin Harper; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rosin; resin acids; HPLC ESI-MS; air sampling; urine samples; wood pellets; wood dust; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The aims of the work this thesis is based upon were to develop convenient analytical procedures for determining resin acids in biological and environmental matrices, and apply them to enhance understanding of the occurrence, exposure to and uptake by exposed individuals of resin acids. Particular focus has been on the workplace environment of the Swedish wood pellets industry. LÄS MER
