  2. 16. Modification of Paper into Conductive Substrate for Electronic Functions : Deposition, Characterization and Demonstration

    Author : Elson Montibon; Magnus Lestelius; Lars Järnström; Jouko Peltonen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic paper; electroconductive paper; flexible electronics; conducting polymer; ionic liquids; fiber network; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : The thesis investigates the modification of paper into an ion- and electron-conductive material, and as a renewable material for electronic device. The study stretches from investigating the interaction between the cellulosic materials and the conducting polymer to demonstrating the performance of the conductive paper by printing the electronic structure on the surface of the conductive paper.

  4. 17. Outdoor Recreation and Environmentalism : Social and Spatial Perspectives

    Author : Daniel Wolf-Watz; Klas Sandell; Tom Mels; Karlstads universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human geography; Kulturgeografi; Kulturgeografi; Human Geography;

    Abstract : Outdoor recreation and environmentalism are interlinked phenomena. Historically, they have clear parallels; both emerged at the dawn of the last century, drew inspiration from the Romantic Movement, and were reactions against elements in the modern industrialized and urbanized society.

  5. 18. Underwater radiated noise from Point Absorbing Wave Energy Converters : Noise Characteristics and Possible Environmental Effects

    Author : Kalle Haikonen; Jan Sundberg; Sigray Peter; Uppsala universitet; []
    Keywords : Wave energy conversion; renewable energy; environmental impact; marine ecology; underwater noise;

    Abstract : The conversion of wave energy into electrical energy has the potential to become a clean and sustainable form of renewable energy conversion. However, like all forms of energy conversion it will inevitably have an impact on the marine environment, although not in the form of emissions of hazardous substances (gases, oils or chemicals associated with anticorrosion).

  6. 19. Mathematical modelling approach to collective decision-making

    Author : Natalia Zabzina; Denis Gaidashev; Torbjörn Lundh; Uppsala universitet; []
    Keywords : collective behaviour; collective decision-making; communication mechanisms; positive feedback; mathematical modelling; bifurcation phenomena; steady state solutions; symmetry breaking; symmetry restoring; diffusion-limited aggregation; fractal dimension;

    Abstract : In everyday situations individuals make decisions. For example, a tourist usually chooses a crowded or recommended restaurant to have dinner. Perhaps it is an individual decision, but the observed pattern of decision-making is a collective phenomenon. READ MORE

  7. 20. "Please Mind the Grey Digital Divide" : An Analysis of Digital Public Policies in Light of the Welfare State (Sweden and Greece)

    Author : Sofia Alexopoulou; Joachim Åström; Martin Karlsson; Elin Wihlborg; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; grey digital divide; welfare regimes; digital public policies; digital technologies; older people;

    Abstract : This thesis examines the grey digital divide and digital policies in the divergent welfare regimes of Sweden and Greece. The grey digital divide is a serious problem not only for the individual but also for society. The grey digital divide signifies the inability of older people to utilize digital technology. READ MORE
