    Sammanfattning : Cross-country (c.c.) skiing is a complex sport discipline from both physiological and biomechanical perspectives, with varying course topographies that require different proportions of the involved sub-techniques to be utilised. A relatively new event in c. LÄS MER

  3. 17. Hjemmesykepleie til eldre som bor på bygda med uhelbredelig kreft

    Författare :Siri Andreassen Devik; Ove Hellzen; Ingela Enmarker; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The need to deliver high-quality palliative homecare has been underscored in current professional guidelines and demands for efficacy, as well as in the preferences of patients and their families. Indeed, demographic changes and an increased risk of cancer among older people pose challenges to the home healthcare settings in Norway and the rest of the world. LÄS MER

  4. 18. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production

    Författare :Britta Andres; Håkan Olin; Christina Dahlström; Jonas Örtegren; Renyun Zhang; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electric Double-Layer Capacitor; Graphite; Cellulose Nanofibers; Large-Scale; Mass Balancing; Metal-Free;

    Sammanfattning : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. LÄS MER

  5. 19. Paper-based Supercapacitors

    Författare :Britta Andres; Håkan Olin; Mats Sandberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; graphene; graphite; paper; nano fibrillated cellulose; supercapacitor; electric double-layer capacitor; energy storage; roll-to-roll; coating; kinetic energy recovery;

    Sammanfattning : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. LÄS MER

  7. 20. Towards Self-Powered Devices Via Pressure Fluctuation Energy Harvesters

    Författare :Jesus Javier Lechuga Aranda; Bengt Oelmann; Sebastian Bader; Meiling Zhu; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The growing interest in the Internet of Things has created a need for wireless sensing systems for industrial and consumer applications. In hydraulic systems, a widely used method of power transmission in industry, wireless condition monitoring can lead to reduced maintenance costs and increase the capacity for sensor deployment.
