  4. 3. On Crack Dynamics in Brittle Heterogeneous Materials

    Författare :Jenny Carlsson; Per Isaksson; Urban Wiklund; Cecilia Persson; Ralf Denzer; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Sammanfattning : Natural variation, sub-structural features, heterogeneity and porosity make fracture modelling of wood and many other heterogeneous and cellular materials challenging. In this thesis, fracture in such complicated materials is simulated using phase field methods for fracture. LÄS MER

  5. 4. Studies in the Dynamics of Residential Segregation

    Författare :Åsa Bråmå; Roger Andersson; Urban Fransson; Terje Wessel; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; residential segregation; segregation processes; selective migration; distressed neighbourhoods; minority enclaves; Sweden; Kulturgeografi; Human geography; Kulturgeografi;

    Sammanfattning : In four scientific papers, this thesis investigates the processes, in terms of movements of individuals, that have produced, reproduced and transformed patterns of residential segregation in Swedish cities between 1990 and 2000.Paper 1 examines processes of immigrant concentration, and the role of the Swedish majority population in these processes.

  7. 5. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt

    Författare :Arya Vijayan; Maria Viklander; Helene Österlund; Göran Blomqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban snow; Traffic pollution; Suspended solids; Metals; PAHs; Tire and Road wear Particles T RWPs ; Microplastics MPs ; Size fractionation; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.
