  1. 1. Den responsiva demokratin? : Effekter av medborgarnas delaktighet i den lokala demokratin

    Författare :Daniel Wohlgemuth; Anders Westholm; Jan Teorell; Asbjørn Sonne Nørgaard; Uppsala universitet; []
    Nyckelord :Political science; political participation; local democracy; pluralism; responsiveness; policy representation; concurrence; voluntary association; Statsvetenskap;

    Sammanfattning : This thesis aims at investigating the relationship between citizens' attempts to influence decision-making in a democracy and the representativeness of policy outcome. The question is to what extent the degree of citizen political activity, in terms of expressing policy preferences, affects: 1. LÄS MER

  3. 2. Polymer Gels and their Interactions with Ionic Surfactants

    Författare :Olof Rosén; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Polymer-Surfactant Interactions; Modified Polymers; Binding Isotherm; Polymer Gels; Swelling Isotherm; Fysikalisk kemi;

    Sammanfattning : The response on chemically crosslinked gels and polymer solutions on the addition of ionic surfactants and/or addition of salt at different temperatures have been studied. All polymers studied are water soluble and slightly hydrophobic or hydrophobically modified. LÄS MER

    Sammanfattning : Hemicellulose is the second most abundant component in wood and is an important renewable resource  that is used in films, paper composites and biofuels.  Hemicelluloses  have  several  advantages,  including  their abundance,  degradability  and  renewability. LÄS MER

  5. 4. Controlled Polymer Grafting from Nanoparticles for the Design of Dielectric Nanocomposites

    Författare :Martin Wåhlander; Eva Malmström; Anna Carlmark; Henrik Hillborg; Sanat K. Kumar; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The interest for polymeric nanocomposites has rapidly grown during the last decades, fuelled by the great potential and superior properties of nanoparticles (NPs). The production volumes of commercial NPs have increased exponentially during the last ten years, and the quality has been significantly improved. LÄS MER

  7. 5. Hydrogel-based pH-sensors : Development and characterisation of optical and electrical pH sensors based on stimuli-responsive hydrogels

    Författare :Krister Hammarling; Hans-Erik Nilsson; Magnus Engholm; Henrik Andersson; Guido Perrone; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogel; fiber optics; printed electronics; pH; sensor;

    Sammanfattning : The ability to measure the chemical parameter pH is of high importance in many areas. With new government regulations and evolving markets, there is a strong motivation for improving such measurements and conducting research on new types of pH sensors and sensor materials. LÄS MER
