  1. 6. The environment knows no borders : Investigating the collective challenge of governing policy issue interdependencies

    Författare :Johanna Hedlund; Örjan Bodin; Daniel Nohrstedt; Erik Andersson; Michele-Lee Moore; Jale Tosun; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; policy issue interdependencies; collaborative governance; networks; environmental problems; policy issues; policy actors; boundary-spanning; water governance; cross-border climate impacts; food trade systems; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Many of today’s most pressing environmental problems cross-cut jurisdictional, geographical, and administrative boundaries, creating interdependencies between different locations and between policy issues that no single actor can address alone. In practice, however, environmental policy is still often contained within the traditional responsibilities of the public sector and frequently judged ineffective, particularly in the European context.

  2. 7. The Membrane-Spanning Domain of Complex I Investigated with Fusion Protein Techniques

    Författare :Maria Trane; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NuoN; NuoM; NuoL; covalent bound heme; Bacillus subtilis; Escherichia coli; membrane protein; His-tag; Cytochrome c; NADH:quinone oxidureductase; fusion protein;

    Sammanfattning : NADH:quinone oxidoreductase, or complex I, is a large, complex and poorly understood bioenergetic enzyme in the respiratory chain of living organisms. The enzyme has a conserved core structure, comprising fourteen protein subunits: Seven subunits protrude from the membrane and contain a flavin prosthetic group and eight iron-sulfur clusters that guide electrons from the oxidation of NADH towards the quinone binding site(s).

  3. 8. Digitalized industrial equipment : an investigation of remote diagnostics services

    Författare :Katrin Jonsson; Jonny Holmström; Ola Henfridsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boundary-spanning practices; e-maintenance; industry; information technology; IT-enabled services; remote diagnostics systems; ubiquitous computing; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

    Sammanfattning : With the ubiquity of digitalization, digital convergence of applications, devices, networks and artifacts presents both challenges and opportunities for individuals, organizations and society. Physical artifacts that were not digital in the recent past are now increasingly becoming intertwined with digital components, providing them with digital capabilities. LÄS MER

  4. 9. Progress in Hierarchical Clustering & Minimum Weight Triangulation

    Författare :Drago Krznaric; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer technology; Systems engineering; minimum spanning tree; complete linkage; hierarchical clustering; minimum weight triangulation; greedy triangulation; Data- och systemvetenskap;

    Sammanfattning : In this thesis we study efficient computational methods for geometrical problems of practical importance and theoretical interest. The problems that we consider are primarily complete linkage clustering, minimum spanning trees, and approximating minimum weight triangulation. Below is a list of the main results proved in the thesis. LÄS MER

  5. 10. Aspects of Spatial Random Processes

    Författare :Olle Häggström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subshift of finite type; measure of maximal entropy; Ising model; Gibbs measure; uniform spanning tree; first passage percolation; asymptotic shape; first passage percolation;

    Sammanfattning : This thesis consists of five papers dealing with various aspects of spatial random processes. In the first three papers the main focus is on a special class of such processes, namely measures of maximal entropy for subshifts of finite type. LÄS MER
