  1. 1. Multilayered Governance : Pesticides in the South - environmental concerns in a globalised world

    Författare :Sylvia Karlsson; Anders Hjort av Ornäs; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multilayered governance; CPRs; global commons; pesticides; global environmental change; institutions; knowledge; values; mismatches; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Environmental issues increasingly demonstrate local-global linkages in driving forces and effects. Policy responses are initiated at local, national and global levels. The successful management of such cross-level environmental issues involves co-ordinated and co-operative policies and action among stakeholders at several levels of governance. LÄS MER

  3. 2. Nanoscale Reaction Systems

    Författare :Karin Fromell; Karin Caldwell; Francesco Dondi; Uppsala universitet; []
    Nyckelord :Life sciences and physical sciences; nanoparticles; Sedimentation Field-Flow Fractionation; bioaffinity; multilayered functionalization; protein attachment; diagnostics; bioluminescence; NATURVETENSKAP;

    Sammanfattning : The work presented in this thesis describes the use of polystyrene nanoparticles as model surfaces for bioanalytical work. Nanoparticles constitute convenient platforms for the attachment of bioactive agents, and receptor coated particles offer high local concentration of binding sites for specific ligands with minimal steric hindrance.

    Författare :Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Wennhage Wennhage; Camille Perrot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poroelastic media; anisotropy; plane waves; multilayered systems; dynamics; acoustics; optimisation; matériaux poro-visco-élastique; anisotropie; ondes planes; panneaux multicouches; dynamique; acoustique; optimisation; Poroelastiska material; anisotropi; planvågor; flerskiktssystem; dynamik; akustik; optimering; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. LÄS MER

  5. 4. Fabrication, Characterization and Applications of Porous Silicon Thin Films and Multilayered Systems

    Författare :Shahin Zangooie; John A. Woollam; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Variable angle spectroscopic ellipsometry was used for characterization of single- as well as multilayered systems of porous silicon. In addition to the complex structures such as Bragg reflectors and Fabry-Pérot filters, more advanced continuos porosity profiles were manufactured in a controlled manner. LÄS MER

  7. 5. Statistical energy analysis and variational principles for the prediction of sound transmission in multilayered structures

    Författare :Mathias Barbagallo; Svante Finnveden; Jean-Louis Guyader; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical energy analysis; porous materials; biot theory; variational principles; hamilton principle; double walls; multilayered structures; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer;

    Sammanfattning : Multilayered structures have many application in industry and society: they have peculiar properties and serve a variety of purposes, like structural support, thermal insulation, vibrational and acoustic isolation. This thesis concerns the prediction of sound transmission in multilayered structures. LÄS MER
