  1. 1. Long-Term Tracheostomy : Outcome, Cannula care, and Material Wear

    Detta är en avhandling från Stockholm : Karolinska Institutet

    Författare :Gunilla Björling; Sophiahemmet Högskola.; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tracheostomy; long-term care; INTERDISCIPLINARY RESEARCH AREAS Caring sciences Nursing; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Vårdvetenskap Omvårdnad; Long-term tracheostomy; Respiratory failure; Hospital care; Tracheostomy care; Decontamination; Trachestomy tube; Material degradation; Polymeric material; Health-related quality of life; Long-term tracheostomy; respiratory failure; hospital care; tracheostomy care; decontamination; tracheostomy tube; material degradation; polymeric material; and health-related quality of life;

    Sammanfattning : Do people with long-term tracheostomy need hospital care? Which cleaning method is most appropriate for decontamination of inner cannulae? Are tracheostomy tubes changed for rational reasons? There is clearly a lack of evidence based research in this field and the clinical guidelines available are often based on local practice. A tracheostomy is a created opening in trachea to facilitate breathing. LÄS MER

  2. 2. Polymeric materials in nuclear power plants : Lifetime prediction, condition monitoring and simulation of ageing

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Erik Linde; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nuclear power plants generate a significant part of the world’s electrical power consumption. However, many plants are nearing the end of their designed lifetime, and to extend the lifetime it is important to verify that every component can withstand the added service time. This includes polymeric materials, which become brittle with time. LÄS MER
