  1. 6. Palaeosurfaces and palaeovalleys on North Atlantic previously glaciated passive margins : reference forms for conclusions on uplift and erosion

    Författare :Johan M. Bonow; Karna Lidmar-Bergström; Clas Hättestrand; Jens-Ove Näslund; Mats Olvmo; Adrian Hall; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palaeosurface; palaeovalley; uplift; valley; incision; glacial erosion; weathering; Neogene; southern Norway; West Greenland; Earth sciences; Geovetenskap;

    Sammanfattning : Palaeosurfaces and palaeovalleys are landforms under destruction in the present climate and/or tectonic regime, and thus mainly reflect processes not active today. Uplifted palaeosurfaces exist along the formerly glaciated passive continental margins around the North Atlantic. LÄS MER

  3. 7. Experimental and theoretical study of post-dryout heat transfer in annuli with flow obstacle

    Författare :Ionut Anghel; Henryk Anglart; Dariusz Mikielewicz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; annulus; flow obstacles; critical heat flux; post-dryout; thermal margins; boiling water reactor; Fysik; Physics;

    Sammanfattning : An experimental study on post dryout heat transfer regime in annuli with flow obstacles wasconducted in the High-pressure Water Test (HWAT) loop at the Royal Institute of Technologyin Stockholm, Sweden. An annulus with flow obstacles, consisting of two concentric heatedpipes (12.7x24. LÄS MER

  4. 8. Authentic Language : Övdalsk, metapragmatic exchange and the margins of Sweden’s linguistic market

    Författare :David Karlander; Kenneth Hyltenstam; Christopher Stroud; Tomas Riad; Judith T. Irvine; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; authenticity; history of linguistic thought; indexicality; linguistic anthropology; linguistic minorities; metalanguage; metapragmatics; philosophical anthropology; Övdalsk; autenticitet; filosofisk antropologi; indexikalitet; lingvistisk antropologi; metaspråk; metapragmatik; språkliga minoriteter; språkvetenskapens idéhistoria; älvdalska; Bilingualism; tvåspråkighet;

    Sammanfattning : This compilation thesis engages with practices that in some way place stakes in the social existence of Övdalsk (also älvdalska, Elfdalian, Övdalian), a marginal form of Scandinavian used mainly in Sweden’s Älvdalen municipality. The practices at hand range from early 20th century descriptive dialectology and contemporary lay-linguistics to language advocacy and language political debate. LÄS MER

  5. 9. Diagenesis and Reservoir-Quality Evolution of Deep-Water Turbidites: Links to Basin Setting, Depositional Facies, and Sequence Stratigraphy

    Författare :Howri Mansurbeg; Sadoon Morad; Ihsan Al-Aasm; Uppsala universitet; []
    Nyckelord :Bedrock geology; Diagenesis; reservoir quality; active margin; passive margin; depositional facies; sequence stratigraphy; Berggrundsgeologi;

    Sammanfattning : A study of the distribution of diagenetic alterations and their impact on reservoir-quality evolution in four deep-water turbidite successions (Cretaceous to Eocene) from basins in active (foreland) and passive margins revealed the impact of tectonic setting, depositional facies, and changes in the relative sea level. Diagenetic modifications encountered in the turbiditic sandstones from the passive margin basins include dissolution and kaolinitization (kaolin has δ18OV-SMOW = +13. LÄS MER

  7. 10. Viscous-brittle deformation of shallowly emplaced silicic magma : Implications for outgassing and volcanic hazards

    Författare :Taylor Witcher; Steffi Burchardt; Edward Llewellin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magma deformation; magmatic outgassing; magmatic intrusions; rhyolite; Sandfell laccolith; crystal mush; volcanic hazards; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : Silicic magma in the shallow crust has the potential to violently erupt, depending on its ability to release overpressures caused by magmatic volatiles (outgassing). Deformation-induced outgassing is prevalent along volcanic conduit margins, where ascending magma is sheared at high rates. LÄS MER
