  1. 6. An Isostatic Earth Crustal Model : and Its Applications

    Författare :Mohammad Bagherbandi; Lars E. Sjöberg; Martinec Zdeněk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crustal thickness; inverse isostatic problem; isostasy; isostatic compensation; Moho depth; Moho density contrast; downward continuation; Earth sciences; Geovetenskap;

    Sammanfattning :  The Mohorovičič discontinuity (Moho), which is the surface separating the Earth’s crust from the mantle, is of great interest among geoscientists. The Moho depth can be determined by seismic and gravimetric methods. LÄS MER

  3. 7. Return to Work : Assessment of Subjective Psychosocial and Environmental Factors

    Författare :Elin Ekbladh; Lena Haglund; Lars-Håkan Thorell; Hans Jonsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bedömningsinstrument; arbetsterapi; arbetsförmåga; arbetslivsinriktad rehabilitering; sjukfrånvaro; Model of Human Occupation MOHO ; WRI; WEIS; Occupational therapy; Arbetsterapi;

    Sammanfattning : Introduktion: Sjukfrånvaron i Sverige är hög och kunskap om vad som påverkar återgång i arbete efter sjukskrivning behöver utvecklas. I processen kring återgång i arbete är bedömning av arbetsförmåga en viktig del. LÄS MER

  4. 8. Seismic Studies of Paleozoic Orogens in SW Iberia and the Middle Urals

    Författare :Artem Kashubin; Christopher Juhlin; Lars Nielsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reflection seismics; Traveltime tomography; Uralian orogeny; Variscan orogeny; Crustal structure; Geophysics; Geofysik;

    Sammanfattning : Controlled source seismic methods were employed in this study to investigate the reflectivity and velocity structure of two Hercynian orogens – the Uralides and Variscides. Conventional common depth point (CDP) sections from five reflection seismic campaigns and a velocity model obtained from tomographic inversion of wide-angle observations were the main datasets studied from the Middle Urals.

  5. 9. Tectonics of the middle Ural

    Författare :Magnus Friberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : This thesis concerns the crustal structure and tectonic evolution of the Middle Urals. Theresults are based on near-vertical reflection seismic profiling, geological fieldobservations and single zircon geochronology,The Ural Mountains delimit. the eastern margin of Baltica. Prior to PalaeozoicUralian orogeny, this margin was bounded by an ocean. LÄS MER

  7. 10. Scattering of seismic waves in random velocity models : Finite difference simulation

    Författare :Lena Frenje; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The small-scale heterogeneities within the Earth's crust and the effect these heterogeneities have on seismic waves have gained increasing interest in the last 15 years. One approach to study seismic wave scattering is through numerical simulations in random media. LÄS MER
