  1. 31. Measurement and prediction of outcome. Application in fusion surgery for chronic low backpain. The Swedish lumbar spine study

    Författare :Olle Hägg; Göteborgs universitet; []
    Nyckelord :Chronic low back pain; clinical outcome; global assessment; measurement; ; minimal clinically important difference; pain drawing; physical disability; predictors.;

    Sammanfattning : Background: Outcome of surgery for chronic low back pain should be documented ina standardised and reproducible fashion to establish evidence of its benefit. Measurement of outcome requires validated instruments, which have the ability to detect functionalchanges perceived as beneficial by the patient. LÄS MER

  3. 32. Thermochromic VO2-based materials for smart windows : Progress towards applications in buildings

    Författare :Yuxia Ji; Granqvist Claes G.; Niklasson Gunnar A.; Lars Österlund; Dimitra Vernardou; Uppsala universitet; []
    Nyckelord :Thermochromic; Vanadium dioxide; Smart windows; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : Vanadium dioxide is a well-known thermochromic material, whose optical properties can be varied reversibly in response to fluctuation of temperature. It is attractive in various fields due to its unique properties as well as its prospective applications. LÄS MER

  4. 33. Experimental studies of large particles in Newtonian and non-Newtonian fluids

    Författare :Sagar Zade; Luca Brandt; Fredrik Lundell; Ellen Longmire; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; finite-size; particle-laden flows; duct flow; pipe flow; viscoelastic fluid; viscoplastic fluid; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : In everyday human life, laminar flow is arguably an exception whereas turbulent flow is the norm. Yet, the former has been much better understood, naturally since laminar flow renders itself to treatment in a relatively easier fashion compared to turbulence with its chaotic dynamics across multiple scales in space and time.

  5. 34. Lignin nanoparticles for photonic crystals and photothermal films

    Författare :Jinrong Liu; Mika H. Sipponen; Maurice Collins; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lignin; colloid chemistry; films; coatings; nanocomposites; materialkemi; Materials Chemistry;

    Sammanfattning : The development of sustainable materials from biobased resources is essential due to environmental concerns posed by fossil-based materials. Lignin is a chemically complex biopolymer that exists in woody tissues of vascular plants. Lignin has many useful properties such as antioxidant activity, thermal stability, UV-absorbance, rigidity and so on. LÄS MER

  7. 35. Improved Adhesion Between Ethylene Polymers and Aluminium

    Författare :Anders Strålin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Adhesion between aluminium and polymers is important in a wide variety of applications. The aim of the present work was to improve adhesion in polyethylene- aluminium laminates by surface modification of aluminium. The treatments examined were hydration in boiling water and phosphatation by immersion in dilute phosphoric acid solutions. LÄS MER
