  1. 1. Stads- och trafikplaneringens paradigm : en studie av SCAFT 1968, dess förebilder och efterföljare

    Författare :Anders Hagson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; road pattern; traffic environment; urban planning; network; separation; differentiation; principles; road accidents;

    Sammanfattning : Swedish towns have been developed according to the planning guidelines issued by the National Road Administration and the National Board of Urban Planning in 1968; SCAFT 1968 Riktlinjer för stadsplanering med hänsyn till trafiksäkerhet (The SCAFT Guidelines 1968 Principles for urban planning with respect to road safety). The five principles for urban planning suggested are; Locating activities and functions, Separating different classes of traffic, Differentiation within each road network, Clearness, simplicity and uniformity as well as Neighbourhood units.

  3. 2. Cost-Benefit Analysis of Separation Distances - a utility-based approach to risk management decision-making

    Författare :Martin Kylefors; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision-making; cost-benefit; Risk management; land use planning; risk analysis; separation distance;

    Sammanfattning : Decision-making in risk management reflects a normative choice of approach. This dissertation is concerned with the possibility of putting the decision in focus by employing an optimum decision criterion within a utility-based approach. LÄS MER

  4. 3. Structure control by phase separation and influence on mass transport in films for controlled release

    Författare :Helene Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Controlled release; Coating; Cellulose derivatives; Hydroxypropyl cellulose; Solvent evaporation; Ethyl cellulose; Phase separation; Polymer blend; Molecular weight;

    Sammanfattning : Controlled release coatings for oral pharmaceutics are often made of cellulose derivatives. Such coatings can be used to promote a prolonged therapeutic concentration in the blood by a slow drug delivery in the gastrointestinal tract. LÄS MER

  5. 4. Phase Separation and Gelation of Biopolymers in Confined Geometries

    Författare :Sophia Wassén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gelation; gelatin–maltodextrin; whey protein isolate–gellan gum; structure evolution; confinement; biopolymer mixture; image analysis.; spinodal decomposition; phase separation; confocal laser scanning microscopy; microstructure;

    Sammanfattning : Many biopolymer mixtures exhibit segregative phase separation that generates regions enriched in one polymer and depleted in the other. Today, much is known of how phase separating biopolymer systems behaves in bulk phase, and the final morphology can be controlled and tailored with high precision. LÄS MER

  7. 5. Nano-Engineered Contrast Agents : Toward Multimodal Imaging and Acoustophoresis

    Författare :Satya V.V.N. Kothapalli; Dmitry Grishenkov; Lars-Åke Brodin; Andreas Michael Versluis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nano-engineered microbubbles; SPION nanoparticles; Acoustic characterization of MBs; Fracturing mechanism of MBs; Opto-acoustics; Acoustophoresis; Physics; Fysik; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer; Teknik och hälsa; Technology and Health;

    Sammanfattning : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.
