  1. 1. Environmental impact of alum shale mining in Kvarntorp, Närke, Sweden

    Författare :Kristina Åhlgren; Mattias Bäckström; Stefan Karlsson; Roger Herbert; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alum shale; black shale; oil shale; Kvarntorp; uranium; surface water; groundwater; open pits;

    Sammanfattning : Due to scarcity of imported liquid fuel during World War II, alum shale was mined for oil production in the Kvarntorp area 1942-1966. The shale contains both organic matter (kerogen) and elevated concentrations of trace elements such as molybdenum, nickel, uranium and vanadium. LÄS MER

  3. 2. Adaptive immune responses in atherosclerosis - or how to prolong the use of your yellow socks

    Författare :Daniel Kolbus; Kardiovaskulär forskning - immunitet och ateroskleros; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cationized BSA; Atherosclerosis; alum; CD8 T cell; intima-media thickness;

    Sammanfattning : Abstract Atherosclerosis is a multifactorial disease, but an unbalanced immune system plays a critical role in the disease development. A common theory states that a continuous stress to the vascular vessel wall initiates a repair process that however is insufficient to completely heal the tissue. LÄS MER

  4. 3. Thermal Modelling of the Caledonian Basin, Scandinavia and a Northern North Sea Profile

    Författare :Jörgen Samuelsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; petroleum; vitrinite reflectance; thermal maturation; flexural rigidity; heat flow; suppression; thermal conductivity; North West Shelf; Alum Shale;

    Sammanfattning : The reason for the registered high paleotemperatures of the Scandinavian Alum Shale was investigated by heat flow modelling constrained by vitrinite-like reflectance. The behaviour of the lithosphere under a load was modelled and the paleotemperatures were explained by burial of the Alum Shale in a foreland basin, developing during the Caledonian orogeny. LÄS MER

  7. 5. Weathering of mining waste rock containing alum shale and limestone

    Författare :Erik Puura; KTH; []
    Nyckelord :;

    Sammanfattning : Geochemical processes occurring in the waste rock dumps ofan old phosphate mine, located in Maardu, northem Estonia, havebeen studied and modelled. The waste rock contains pyritic,metalliferous and organic-rich shale, as well as limestone.Production of acidity during pyrite oxidation is a potentialmechanism for heavy metal release. LÄS MER
