1. 21. Integrated Experimental and Computational Study of Precipitation in Martensitic Steels

   Författare :Tao Zhou; Peter Hedström; David San Martin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precipitation; Martensite; Modelling; Thermodynamics; Mechanical Property; Transmission Electron Microscopy; Materials Design; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : Precipitation is a phase transformation process in metallic materials that significantlyaffects properties. The precipitation process that includes nucleation, growth andcoarsening of small particles can be tuned by alloying, deformation, thermal treatment. LÄS MER

3. 22. Creep modelling of particle strengthened steels

   Författare :Hans Magnusson; Rolf Sandström; Wolfgang Blum; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; creep rate modelling; particle hardening; microstructure evolution; dislocation climb; ferritic steels; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Materials used in thermal power plants have to resist creep deformation for time periods up to 30 years. Material evaluation is typically based on creep testing with a maximum duration of a few years. This information is used as input when empirically deriving models for creep. LÄS MER

4. 23. Collective Patient Participation : Patient Voice and Civil Society Organizations in Healthcare

   Författare :Anna Mankell; Johan Vamstad; Mio Fredriksson; Tine Rostgaard; Ersta Sköndal Bräcke högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; patient participation; healthcare; involvement; patient organizations; advocacy; representation; coproduction; marketization; individualization; civil society; Människan i välfärdssamhället; Social välfärd med inriktning mot civilsamhället; The Individual in the Welfare Society; Social Welfare and the Civil Society;

   Sammanfattning : The importance of engaging patients in the development of healthcare services and policy has received increasing attention over the last decades. However, this attention has mainly been directed towards various forms of involvement of individual patients. LÄS MER

5. 24. Cerebrospinal fluid biomarkers in twins with schizophrenia and bipolar disorder

   Författare :Viktoria Johansson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Previously identified cerebrospinal fluid (CSF) biomarkers were studied in 37 twins with schizophrenia or bipolar disorder to determine their genetic and environmental properties. Further, comorbidities and sibling risks were investigated in patients with schizophrenia (n=22,781), bipolar disorder (n=30,761) and depression (n=172,479) in relation to multiple sclerosis (MS) (n=16,467) in a nationwide cohort.

7. 25. Externally unbonded post-tensioned CFRP tendons : a system solution

   Författare :Anders Bennitz; Chris Burgoyne; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; prestress; tendon; external; unbonded; anchorage; beams; CFRP; förspänning; vajer; utanpåliggande; icke vidhäftande; förankring; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : The introduction of Fibre Reinforced Polymers (FRP) to the civil engineering market in the late 1980s resulted in the emergence of a range of new tools for rehabilitating and strengthening concrete structures. Strengthening using FRPs is typically accomplished using non-prestressed externally bonded FRPs. LÄS MER
