  2. 1. The trace of metals : Use, emissions and sediment load of urban heavy metals

    Author : Arne Jonsson; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Urban areas have been considered potential ecological hot spots for metal pollution. This is the result of three trends. First, the 20th century saw a rapid increase in the use of many materials, including metals, in the industrialized world. Second, urbanization has made towns and cities areas nodes of material flows.

  4. 2. Optical Characterization and Energy Simulation of Glazing for High-Performance Windows

    Author : Andreas Jonsson; Arne Roos; Werner Platzer; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; energy simulations; antireflection coatings; dip-coating; optical measurements; spectrophotometer; integrating spheres; low-e windows; solar control windows; smart windows; control strategies; U value; g-value; Engineering physics; Teknisk fysik; Engineering Science; teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : This thesis focuses on one important component of the energy system - the window. Windows are installed in buildings mainly to create visual contact with the surroundings and to let in daylight, and should also be heat and sound insulating. READ MORE

  5. 3. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications

    Author : Jacob Jonsson; Arne Roos; Helen Rose-Wilson; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Photospectrometry; Light scattering; Optical characterisation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : For a long time spectrophotometry has been a powerful method of determining optical material properties. Since the technique measures the parameters of interest, reflectance and transmittance, it is in general easy to use and interpret. READ MORE
