    Sammanfattning : Soft matter, here, liquids and polymers, have adaptability to a surrounding geometry. They intrinsically have advantageous characteristics from a mechanical perspective, such as flowing and wetting on surrounding surfaces, giving compliant, conformal and deformable behavior. LÄS MER

  3. 2. Improved mechanical properties of a polar polythiophene through copolymerization or blending with urethanes

    Författare :Sepideh Zokaei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductive fibers; polar conjugated polymers; mechanical properties;

    Sammanfattning : Polar polythiophenes with oligoethylene glycol side chains are a developing class of materials that are great candidates for energy harvesting and storage as well as bioelectronics. The polar side chains enhance the compatibility with molecular dopants and improve the electrical conductivity and thermal stability of the doped material. LÄS MER

  4. 3. Effects of repetitive work on proprioception and of stretching on sensory mechanisms : implications for work-related neuromuscular disorders

    Författare :Martin Björklund; Håkan Johansson; Albert Crenshaw; Ronny Lorentzon; Måns Magnusson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Repetitive motions; Muscle fatigue; Proprioception; Muscle stretching; Work-related musculoskeletal disorders; Nociception; Ergonomics; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

    Sammanfattning : The aims of the thesis were (i) to investigate the impact of repetitive low-intensity work exposure on proprioception and (ii) to examine effects of muscle stretching (especially sensory effects and effects on muscle nociception) and to relate its application to the prevention, alleviation and/or treatment of work-related neuromuscular disorders. The effects of low-intensity repetitive work on the shoulder proprioception were tested in healthy subjects. LÄS MER
