  1. 11. Snow deposit melt and atmospheric icing : analysis and modelling by weather station data

    Författare :Eva Sundin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Snow deposit melt should be included when dealing with urban run off. Every winter structures experience atmospheric icing. The objective was to develop physically sound models based on weather station data for estimating snow melt and atmospheric icing. LÄS MER

  5. 14. Melt-processing and properties of thermoplastic composites based on ethylene-acrylic acid copolymer reinforced with wood nanocellulose

    Författare :Abhijit Venkatesh; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp fibers; Melt rheology; Composite; Injection moulding; Cellulose; Cellulose nanofibers; Cellulose nanocrystals; Extrusion; Mechanical properties;

    Sammanfattning : Composites reinforced with cellulose nanofibers (CNF), both modified and unmodified cellulose nanocrystals (CNC) and pulp fibers have been prepared through small-scale and large-scale methods. The composites were produced by water-assisted dispersion mixing, drying and compression moulding on the laboratory scale and by extrusion and injection moulding for the large-scale production.
