  3. 2. Quantitative bioimaging in single cell signaling

    Författare :Kristoffer Bernhem; Hjalmar Brismar; Anita Aperia; Lena Scott; Christian Eggeling; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Super resolution imaging; fluoresence; bioimaging; cells; FRET; cluster analysis; labeling; image analysis.;

    Sammanfattning : Imaging of cellular samples has for several hundred years been a way for scientists to investigate biological systems. With the discovery of immunofluorescence labeling in the 1940’s and later genetic fluorescent protein labeling in the 1980’s the most important part in imaging, contrast and specificity, was drastically improved.

    Sammanfattning : The overall purpose of this thesis is to analyze the role of public policies for technological development (i.e., innovation) in the renewable energy sector. The thesis consists of an introductory part and three self-contained papers. LÄS MER

  5. 4. Mellan flykt och förändring : Utopiskt platsskapande i 1970-talets alternativa miljö

    Författare :Kristoffer Ekberg; Forskarskolan i historia; []
    Nyckelord :intentional communities; Utopian studies; Prefiguration; social movements; place; environmental movements; counterculture;

    Sammanfattning : The Swedish alternative movement’s place-making activities in the seventies have been understood as an attempt to escape the political sphere. In this thesis, I investigate the ideas and practices of societal transformation seen in rural intentional communities and, to a lesser degree, urban sites. LÄS MER

  7. 5. Transversal media practices : media archaeology, art and technological development

    Författare :Kristoffer Gansing; Beryl Graham; Malmö högskola; []
    Nyckelord :media archaeology; transversality; technological development; new media; media art; alternative media; practice-based research; cultural production; artistic research; overhead projector; television; remediation; imaginary media;

    Sammanfattning : Transversal Media Practices work across specific situations of technological development, critically examining and redefining the terms of production in different media by bringing heterogeneous histories, institutions, actors and materialities into play with one another. This dissertation is all about trying out and refining the methodologies of such transversal media practices, in the end outlining a conceptual set of tools for further development. LÄS MER
