  1. 21. Chemical emissions from building structures : emission sources and their impact on indoor air

    Författare :Annika Glader; Ingrid Liljelind; Berndt Stenberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; VOC; building structures; emissions; health effects; moisture damage; PCA; OPLS; inomhusluft; VOC; konstruktioner; emissioner; hälsoeffekter; byggnadsmaterial; fuktskada; PCA; OPLS; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. LÄS MER

  3. 22. Timber/Glass Adhesive Bonds for Structural Applications

    Författare :Louise Blyberg; Erik Serrano; Kent Persson; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Byggteknik; Civil engineering;

    Sammanfattning : Timber with its natural appearance and glass with its transparency may be appealing material for architects and users of modern buildings. Glass is a brittle material, but it is about six times stiffer than timber. Combined appropriately, the materials could form different types of composite products, e.g. LÄS MER

  4. 23. Vibrations from Railway Traffic : Computational Modeling and Analysis

    Författare :Jens Malmborg; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Train-induced vibrations; ground vibration; wave propagation; soil dynamics; finite element method; soil stiffening; critical velocity;

    Sammanfattning : The population is growing, and an increasing proportion of the population lives in urban areas. As a consequence, human exposure to noise and vibrations is increasing; two major sources being railway and road traffic. Larger and denser cities lead to a higher amount of traffic close to where people work and live. LÄS MER

  5. 24. Measurement and perception of sound insulation from 20 Hz between dwellings

    Författare :Rikard Öqvist; Fredrik Ljunggren; Roger Johnsson; Anders Ågren; Berndt Zeitler; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound insulation; Lightweight constructions; Annoyance; Measurement uncertainty; Low frequency; Building Acoustics; Walking noise; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Population growth and urbanization are projected by the United Nations to add 2,5 billionpeople to the world’s urban population by 2050. We need to construct buildings in anunprecedented scale to meet global housing demand. Sustainable development is critical. LÄS MER

  7. 25. Shipworm ecology in Swedish coastal waters

    Författare :Christin Appelqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Shipworms (Teredinidae) are marine bivalves adopted for boring into submerged wood, which they efficiently fragmentize and consume. They thereby perform a vital ecosystem service, yet simultaneously they cause extensive damage to important man-made marine structures. LÄS MER
