  1. 11. Nonlinear Dust Particle Dynamics and Collective Effects in Complex Plasmas

    Författare :Gianfranco Sorasio; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Complex Dusty Plasmas; Self excited; Nonlinear; Forced Oscillations; Electrostatic Instabilities in current-carrying magnetoplasmas; Cross-field instabilities in magnetized dusty plasmas; Dust Acoustic Waves; Electrostatic Dust Cyclotron Waves; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Theoretical studies of dusty plasmas have been performed by focusing attention principally on collective phenomena and on grain motion. This thesis consists of a collection of seven published papers that explore both the collective behavior of a complex plasma system as well as the dynamics of grains in plasmas. LÄS MER

  3. 12. Controllability of Complex Networks at Minimum Cost

    Författare :Gustav Lindmark; Claudio Altafini; Anders Helmersson; Franco Garofalo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The control-theoretic notion of controllability captures the ability to guide a system toward a desired state with a suitable choice of inputs. Controllability of complex networks such as traffic networks, gene regulatory networks, power grids etc. can for instance enable efficient operation or entirely new applicative possibilities.

  4. 13. Amphiphilic Peptide Interactions with Complex Biological Membranes : Effect of peptide properties on antimicrobial and anti-inflammatory effects

    Författare :Shalini Singh; Martin Malmsten; Per Hansson; Debora Berti; Uppsala universitet; []
    Nyckelord :LPS; Antimicrobial; Peptide; Inflammation; Infections; Liposome; Binding; PEG; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Sammanfattning : With increasing problem of resistance development in bacteria against conventional antibiotics, as well as problems associated with diseases either triggered or enhanced by infection, there is an urgent need to identify new types of effective therapeutics for the treatment of infectious diseases and its consequences. Antimicrobial and anti-inflammatory peptides have attracted considerable interest as potential new antibiotics in this context. LÄS MER

  5. 14. Interfibre Joint Strength under Mixed Modes of Loading

    Författare :Mikael S. Magnusson; Sören Östlund; Kaarlo Niskanen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interfibre joint strength; fibre-fibre cross; paper mechanics; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The load carrying capacity of interbre joints are one of the key entities for build-up of strength inpaper materials. In order to gain insight in how to tailor the macroscopic properties of such materialsby chemical and/or mechanical treatments at a microscopic level, direct measurement of individualbre{bre crosses are typically performed.

  7. 15. Att läsa bilder med kroppen : En studie om yngre förskolebarns kommunicerande

    Författare :Hanna Thuresson; Marie Nordberg; Christina Olin-Scheller; Anna Klerfelt; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Literacy; Multimodalitet; bilder; förskolebarn; Kropp; Kommunikation; Meningsskapande; Pedagogiskt arbete; Educational Work;

    Sammanfattning : The aim of this study is to examine young pre-school children´s literacy with a focus on their communication about pictures.  Based on the ethnographic method and video-recorded observations, this study demonstrates how young children communicate about pictures in various media.
