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

   Författare :Gunilla Björling; Unn-Britt Johansson; Claes Frostell; Agneta Markström; Bengt Midgren; Sophiahemmet Högskola; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long-term tracheostomy; Respiratory failure; Hospital care; Tracheostomy care; Decontamination; Trachestomy tube; Material degradation; Polymeric material; Health-related quality of life; Nursing; Omvårdnad; 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

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

   Författare :Erik Linde; Ulf Gedde; Mikael Hedenqvist; Sue Burnay; KTH; []
   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

4. 3. Materials Based on Protein Nanofibrils

   Författare :Xinchen Ye; Mikael S. Hedenqvist; Christofer Lendel; Richard T. Olsson; Jonny Blaker; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein nanofibrils; whey protein; hydrogel; film; microfibre; protein structure; mechanical properties;

   Sammanfattning : Protein nanofibrils (PNFs) prepared from whey protein isolate (WPI) at low pH and elevated temperature were processed into materials, i.e. hydrogels, films, foams, and fibres, for different applications where they could potentially be sustainable alternatives to petroleum-based polymers.
