  1. 1. Innovative seismic imaging solutions : From hardrock mineral exploration to quick-clay site characterization

    Författare :Tatiana Pertuz; Alireza Malehmir; Cesare Comina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic methods; mineral exploration; quick-clays; seismic imaging; seismic characterization; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Seismic methods are an efficient and powerful tool to explore the subsurface. It principally helps to gain information on the subsurface structure, bedrock topography, and the nature of the host rock. LÄS MER

  3. 2. Predicting Spatial and Stratigraphic Quick-clay Distribution in SW Sweden

    Författare :Martin Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quick clay; Stratigraphic modeling;

    Sammanfattning : Clay sediments are associated with a wide variety of engineering problems, of which landslides, together with settlement, are the most investigated due to the large associated costs. Quick-clay deposits, which if disturbed can transform into a liquid, pose a serious threat to society in southwestern Sweden and have been involved in several large landslides, sometimes with fatal consequences.

  4. 3. Multidisciplinary Near-Surface Investigation of a Quick-Clay Landslide Prone Area in Southwest Sweden

    Författare :Silvia Salas Romero; Alireza Malehmir; Ian Snowball; Christopher Juhlin; Laura Valentina Socco; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quick-clay; reflection seismic; landslide; southwest Sweden; borehole logging; physico-chemical properties; hydrogeological modelling; multichannel analysis of surface waves; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Quick-clay landslides are considered one of the most important geohazards in Sweden, Norway, and Canada. The deposits involved are glacial and postglacial clays and silty clays, which are very sensitive to increased stress that may collapse their structure and cause liquefaction. LÄS MER

  5. 4. Long shifts, short rests and vulnerability to shift work

    Författare :John Axelsson; Torbjörn Åkerstedt; Ulf Lundberg; Phil Tucker; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sleep; alertness; sleepiness; shiftwork; compressed working hours; long shifts; 12h shifts; quick returns; quick change-overs; tolerance; gender; Psychology; Psykologi;

    Sammanfattning : At the same time as many urban economies are developing into 24-hour societies it is becoming increasingly popular amongst shift workers to compress their working hours. This is done by working longer shifts (>8h) and/or restricting free time (... LÄS MER
