  1. 1. Intrinsically Proton-Conducting Benzimidazole Units Tethered to Different Polymer Chain Architectures

    Författare :Christian Persson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Kemiteknik och kemisk teknologi; Polymer technology; Chemical technology and engineering; Materiallära; materialteknik; Material technology; Makromolekylär kemi; Macromolecular chemistry; proton-exchange membrane fuel cell; structure diffusion; thiol-ene reaction; segmental mobility; high temperature; benzimidazole; block copolymers; polymer electrolyte; anhydrous proton conductivity;

    Sammanfattning : Proton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for powering cars, laptops, buildings etc. LÄS MER

  4. 3. Signs, symptoms, and disability related to the musculo-skeletal system : studies of home care personnel and patients with fibromyalgia

    Författare :Gunnar Lundberg; Ulrich Moritz; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Low back pain (LBP) and neck/shoulder pain are the major reasons for sickness absence and disability pensions in Sweden. The working situation of home care personnel in Sweden frequently requires heavy lifting and forward bending and workers report high prevalences of work-related musculo-skeletal pain and high frequencies of work accidents, especially lower back injuries.

  5. 4. Bimanual movement control : insights from golf ball striking

    Författare :Fredrik Tinmark; Toni Arndt; John Rasmussen; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Sammanfattning : The aim of this thesis was to gain insight into the control of complex bimanual movements that are both fast and accurate. For this, skilled golf ball striking was used as a model in two experimental studies (I and III). LÄS MER

  7. 5. Functionalization of polymer electrolytes for electrochromic windows

    Författare :İlknur Bayrak Pehlivan; Gunnar A. Niklasson; Claes-Göran Granqvist; Michel Aegerter; Uppsala universitet; []

    Sammanfattning : Saving energy in buildings is of great importance because about 30 to 40 % of the energy in the world is used in buildings. An electrochromic window (ECW), which makes it possible to regulate the inflow of visible light and solar energy into buildings, is a promising technology providing a reduction in energy consumption in buildings along with indoor comfort.
