    Sammanfattning : Temperature is one of the most decisive parameters when it comes to determining characteristics and distributions of life worldwide. For plants, as sessile organisms, it is particularly important to be able to deal with the temperatures they are exposed to at a given location. LÄS MER

    Sammanfattning : Equating Earth’s existence to 24 hours, we, the Homo sapiens, came about in the last four seconds. Fossil fuel came to our knowledge with mass extraction dating from the Industrial Revolution two centuries ago, in other words 4 milliseconds out of Earth’s 24-hour equivalent lifetime. LÄS MER

  7. 15. Thermal ice pressure on structures in ice covers

    Författare :Lennart Fransson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : A method to estimate thermal ice pressure is proposed. Temperature-history and stress-history in a confined ice sheet heated at the surface is illustrated with numerical examples. Material parameters for columnar lake ice has been evaluated from classical laboratory experiments and a field program presented here. LÄS MER
