  1. 21. Reliability and Life Cycle Cost Modelling of Mining Drilling Rigs

    Författare :Hussan Hamodi; Luleå tekniska universitet; []

    Sammanfattning : In the context of mining, drilling is the process of making holes in the face and walls of underground mine rooms, to prepare those rooms for the subsequent operation, which is the charging process. Due to the nature of the task, drilling incurs a high number of drilling rig failures. LÄS MER

  3. 23. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Författare :Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Sammanfattning : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. LÄS MER

  4. 24. Long-term performance of water repellants on rendered autoclaved aerated concrete

    Författare :Hülya Kus; Hulya Kus; KTH; []
    Nyckelord :water repellants; renderings; autoclaved aerated concrete; surface treatments; long-term performance; degradation; natural weathering; artificial weathering; moisture monitoring;

    Sammanfattning : Many failures of external walls made of porous buildingmaterials are caused by excessive moisture content,particularly after driving rain and under long duration ofmoist conditions. Lack of sufficient protection againstexposure conditions is one of the reasons for external wallsprematurely demonstrating failures, i.e. LÄS MER

  5. 25. On the operation of light-emitting electrochemical cells

    Författare :E. Mattias Lindh; Ludvig Edman; Thomas Wågberg; Thomas Lanz; Sebastian Reineke; Umeå universitet; []
