  3. 2. Impact of Water-Level Variations on Slope Stability

    Författare :Jens Johansson; Lars Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Waterfront-soil slopes are exposed to water-level fluctuations originating from either natural sources, e.g. extreme weather and tides, or from human activities such as watercourse regulation for irrigation, freshwater provision, hydropower production etc. LÄS MER

  4. 3. Mechanical properties of artificial snow

    Författare :Nina Lintzén; Lars Vikström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Mechanical properties of snow have been a subject of research since the mid-20th century. Theresearch done is based on natural snow. During the last decades the winter business industryhas been growing and also the interest for constructing buildings and artwork of snow. Suchconstructions are generally built using artificial snow, i. LÄS MER

  5. 4. Black liquor gasification : burner characteristics and syngas cooling

    Författare :Mikael Risberg; Mats Lindblom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Black liquor gasification at high temperature is a promising alternative to the conventional recovery boiler process used in chemical pulp mills today. Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel.

  7. 5. Characterization and solidification of arsenic-rich cyanided tailings

    Författare :Roger Hamberg; Lena Sultan; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Information on the occurrence of As species and iron sulphide minerals in tailings is essential for predicting therelease of As over extended period of time. Tailings originating from a goldmine in northern Sweden with low content of trace elements except for As were used for this purpose. The dominating sulphides were pyrrhotite and arsenopyrite. LÄS MER
