  1. 1. Moisture Conditions in Exterior Wooden Walls and Timber During Production and Use

    Författare :Lars Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory test; MRD-index; moisture; driving rain; hysteresis; wood; precipitation; timber; weather barrier; mould growth; façade; wall; wind barrier; measurement; field test; mold;

    Sammanfattning : Thermal insulation of building envelopes has improved over the years. This means that building envelope have become more susceptible to defects, with an increased risk of moisture damage. The criteria for energy consumption have become more rigorous, but the shift should not lead to moisture problems. LÄS MER

  3. 2. Solar wind ions inside the induced magnetosphere of Mars

    Författare :Catherine Dieval; Christian Mazelle; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : The subject of the thesis is analysis and modeling of the entry, transport, and atmospheric precipitation of solar wind ions, H+ and He2+, into the induced magnetosphere of Mars. The solar wind is a flow of charged particles emitted by the Sun. The solar wind carries with it a magnetic field, the interplanetary magnetic field (IMF). LÄS MER

  4. 3. Interaction of Hurricanes and Natural Coastal Features: Implications for Storm Damage Reduction

    Författare :Ty Wamsley; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Louisiana; Barrier island; Vegetation; Flooding; Waves; Storm surge; Hurricanes; Mathematical modeling; Storm damage reduction;

    Sammanfattning : It is generally acknowledged that wetlands and barrier islands can reduce surge and waves. However, while a general qualitative understanding of these interactions is available in the scientific literature, quantification of these interactions is lacking and has previously been based on limited data of relatively poor quality.

  5. 4. The solar wind protons inside the induced magnetosphere of Mars

    Författare :Catherine Dieval; Maria Hamrin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : Mars is an unmagnetized planet. Mars has no intrinsic magnetic field but has local magnetic anomalies in the crust. The solar wind, which is the plasma flowing from the Sun at supersonic speed, interacts with the magnetic fields of the currents induced in the conductive Martian ionosphere, deviates and slows down to subsonic speeds.

  7. 5. Protection against cold in prehospital trauma care

    Författare :Otto Henriksson; Ulf Björnstig; Tore Vikström; Peter Naredi; Hannu Rintamäki; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypothermia; prehospital trauma care; emergency medical services; passive warming; thermal insulation; heat loss; body temperature regulation; kirurgi; Surgery;

    Sammanfattning : Background: Protection against cold is vitally important in prehospital trauma care to reduce heat loss and prevent body core cooling. Objectives: Evaluate the effect on cold stress and thermoregulation in volunteer subjects byutilising additional insulation on a spineboard (I). LÄS MER
