    Sammanfattning : Despite the past four decades of service experiences with polymeric insulators in power systems all over the world, an adequate standard allowing for proper selection of polymeric materials for applications in high voltage outdoor environments has still been lacking. Therefore CIGRE Working Group D1. LÄS MER

  3. 2. Polymer-coated paper and board - Role of substrate, polymer characteristics and additives

    Författare :Thomas Schuman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface energy; latex; surface roughness; corona; contact angle; barrier properties; liquid sorption; surface treatment; calendering; poly vinyl alcohol ; coating;

    Sammanfattning : The surface roughness of paper or board has a significant influence on the homogeneity of an applied polymer film, and this thesis discusses how it may be improved by a surface treatment, e.g. high-temperature calendering or precoating. LÄS MER

  5. 4. Engineering Nanotherapeutic Strategies for Osteoarthritis Treatment

    Författare :Ula von Mentzer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoparticles; nanomedicine; cartilage; osteoarthritis;

    Sammanfattning : Osteoarthritis (OA), the most prevalent joint disorder, is characterized by the degeneration of cartilage tissue leading to pain, stiffness, and impaired mobility. Primarily affecting the elderly, OA can also impact athletes, postmenopausal women, and individuals with conditions like diabetes. LÄS MER

  7. 5. Aspects of decisions to withhold and withdraw life-sustaining treatment in intensive care

    Författare :Alma Nordenskjöld Syrous; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; critical care; end-of-life decision-making; intensive care; life-sustaining treatment; withdraw; withhold;

    Sammanfattning : End-of-life decision-making is required when the patient no longer benefits from available treatment options and there is a need to redirect medical treatment goals from cure to palliative care. End-of-life decisions are multifaceted and complicated processes for intensive care physicians. LÄS MER
