  2. 21. Ageing and Caring as Couples with Disabilities

    Author : Cristina Joy Torgé; Eva Jeppsson Grassman; Anna Whitaker; Lotta Holme; Anneli Anttonen; Linköpings universitet; []
    Keywords : Care; physical disability; ageing; older couples; conjoint interviews; Omsorg; funktionshinder; åldrande; äldre par; parintervjuer;

    Abstract : In gerontology and care research, care is often studied in ways in which older people and people with disabilities are portrayed as dependent on the care of younger or non-disabled people. This thesis, in contrast, studies care provided by people that are both old and have physical disabilities. READ MORE

  4. 22. Assessment of the lifetime of district heating pipes

    Author : Alberto Vega; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FTIR; rigid polyurethane foam; artificial ageing; {District heating pipes; natural ageing; degradation mechanisms; mechanical performance;

    Abstract : This thesis is concerned with the degradation and assessment of the lifetime of district heating pipes, where accelerated ageing is used to study the degradation in a short time frame. The project was divided into four interrelated parts. READ MORE

  5. 23. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications

    Author : Elanghovan Natesan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder head; aluminium; constitutive models; thermo-mechanical fatigue; fatigue; ageing; mechanical behaviour; A356;

    Abstract : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.

  6. 24. The influence of ageing on the salt-frost resistance of concrete

    Author : Peter Utgenannt; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; materialteknik; Building construction; Material technology; freeze thaw testing; hydration; field exposure; carbonation; drying; Byggnadsteknik; ageing; salt-frost resistance; Concrete;

    Abstract : Abstract This thesis presents the results of an investigation of the influence of ageing on the salt-frost resistance of concrete. The ageing mechanisms investigated were hydration, drying and carbonation. READ MORE

  7. 25. Understanding the Role of Molybdenum on the Precipitation in PH Stainless Steels

    Author : MARCUS ANDERSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon; Precipitation; ageing; EFTEM; molybdenum; atom probe.; martensitic PH stainless steel;

    Abstract : The main part of the present work concerns studies of the influence of molybdenum on the microstructure of martensitic PH stainless steels, during ageing at 475°C. A short investigation of the silicon impact has also been conducted. READ MORE
