    Abstract : Wood plastic composite (WPC) materials have seen a continuous market growth worldwide in the last decade. So-called extruded WPC profiles are today mainly used in outdoor applications, e.g. decking, railing and fencing. READ MORE

  5. 3. Figures of time : on the phenomenology of cinema and temporality

    Author : Malin Wahlberg; Michael Renov; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; film theory; phenomenology; aesthetic theory; temporality; duration; speed; photography; city film; documentary; experimental cinema; Film; Filmvetenskap; Cinema Studies; filmvetenskap;

    Abstract : Image and time represent a favored issue among theorists and practitioners in the history of cinema, where discussion is related to the ingenious machine, the new art, as well as the experience of film. Looking back on this debate, and considering recent accounts of 'time-images,' it is striking to note how the problem has always oscillated between issues of the medium specific and issues of film experience; that is, the ontology of cinema as a time-bound medium, the quality of rhythm, duration, and recorded views, and, not least, the sensory and affective impact of mediated sound-images.

  6. 4. On Textile Farming : Seeds as Material for Textile Design

    Author : Svenja Keune; Delia Dumitrescu; Högskolan i Borås; []
    Keywords : HUMANIORA; HUMANITIES; Textiles and Fashion Design ; Textil och mode konstnärlig ;

    Abstract : Presently, designing with living systems such as insects, fungi and bacteria has become an area of extended interest, proposing collaborative processes of designing and manufacturing - as a solution for symbiotic ways of living. On the scale of the interior, modern systems for interior gardening, combining both functional, e.g. READ MORE

  7. 5. Surface coatings as xenon diffusion barriers on plastic scintillators : Improving Nuclear-Test-Ban Treaty verification

    Author : Lisa Bläckberg; Mattias Klintenberg; Henrik Sjöstrand; Anders Ringbom; Stephan Pomp; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plastic scintillator; Radioxenon; Diffusion barrier; Surface coating; Atomic Layer Deposition; Comprehensive Nuclear-Test-Ban Treaty; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis investigates the ability of transparent surface coatings to reduce xenon diffusion into plastic scintillators. The motivation for the work is improved radioxenon monitoring equipment, used with in the framework of the verification regime of the Comprehensive Nuclear-Test-Ban Treaty. READ MORE
