1. 1. Melt spinning of poly(vinylidene fluoride) mono- and bicomponent fibres and yarns : the formation of piezoelectric beta-phase crystallinity

   Författare :Anja Lund; Högskolan i Borås; []
   Nyckelord :fibres; PVDF; Textilteknologi;

   Sammanfattning : The present study investigates the possibilities of manufacturing piezoelectric polymer fibres or yarns for integration into textile materials. The polymers known to give the strongest piezoelectric effects are poly(vinylidene fluoride) (PVDF) and some of its copolymers. LÄS MER

3. 2. Fuel Cells and Biogas

   Författare :Lars Hedström; Per Alvfors; Peter Lund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air bleed; biogas; carbon dioxide; carbon monoxide; current distribution; dilution; efficiency; energy conversion; energy systems; experimental; fuel cell; fuel cell systems; PEFC; poisoning; reformate; SOFC; Chemical energy engineering; Kemisk energiteknik;

   Sammanfattning : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. LÄS MER

5. 4. Quantitative Magnetic Resonance in Diffuse Neurological and Liver Disease

   Författare :Olof Dahlqvist Leinhard; Peter Lundberg; Anne-Marie Landtblom; Marcel Warntjes; Eva Lund; Göran Starck; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiological physics; Radiofysik;

   Sammanfattning : Introduction: Magnetic resonance (MR) imaging is one of the most important diagnostic tools in modern medicine. Compared to other imaging modalities, it provides superior soft tissue contrast of all parts of the body and it is considered to be safe for patients. LÄS MER

7. 5. Measuring quality of occupational performance based on self-report and observation : development and validation of instruments to evaluate ADL task performance

   Författare :Eva Ejlersen Waehrens; Anne G Fisher; Hans Lund; Bente Danneskiold-Samsöe; Lena von Koch; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; activities of daily living; acquired brain injury; ADL evaluation; ADL task performance; chronic disease; chronic widespread pain; interview; observation; occupational therapy; observation-based evaluation; questionnaire; Rasch measurement; rheumatic diseases; Occupational therapy; Arbetsterapi; Occupational therapy; arbetsterapi;

   Sammanfattning : Background People with rheumatic or neurologic conditions are commonly referred for occupational therapy because of decreased ability to perform ADL tasks. Upon referral, occupational therapists use a client-centred, occupationfocused approach when evaluating a person's perceived and observed quality of ADL task performance to clarify the nature and extent of the person’s problems, plan interventions and determine effectiveness of interventions.
