  1. 16. Assessment of dietary patterns and prey consumption of marine mammals: Grey seals (Halichoerus grypus) in the Baltic Sea

    Författare :Karl Lundström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grey seal; Halichoerus grypus; Baltic Sea; diet; predation; fish; consumption; fatty acid signature analysis; bioenergetics; foraging ecology;

    Sammanfattning : The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. LÄS MER

  3. 17. Den envise bonden och Nordens fransmän : svensk och finsk etnicitet samt nationell historieskrivning i svenska och finlandssvenska läroböcker 1866-1939

    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Textbooks; Ethnicity; History; National Identity; Swedish; Finland-Swedish; läroböcker; etnicitet; historia; nation; nationell identitet; svenskspråkig; Sverige; Finland;

    Sammanfattning : Sweden and Finland were one country for more than 600 years and there are many remaining links between the two countries. Throughout the period, but even today there are Swedish and Finnish populations on both sides of the Gulf of Bothnia. LÄS MER

  4. 18. Satellite Radar Altimetry for Determination of Geoid Undulations and Gravity Anomalies

    Författare :Jonas P. Noréus; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resolution; water vapour; geodesy; geoid undulations; gravity anomalies; precision; kriging; satellite remote sensing; radar altimetry;

    Sammanfattning : The sea level changes both temporally (due to dynamic effects) and spatially (due to sea bottom topography and inhomogeneities in the Earth's crust). Satellite radar altimetry is a remote sensing technique which can be used for e.g. determination of the instantaneous and mean sea level, and gravity anomalies at sea. LÄS MER

  5. 19. Properties and analysis of dioxin-like compounds in marine samples from Sweden

    Författare :Kjell Lundgren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; planar dioxin-like compound; polychlorinated dibenzofuran; polychlorinated biphenyl; polychlorinated naphthalene; alkylated polychlorinated dibenzofuran; high-performance liquid chromatography; PX-21 carbon column; biomagnification factor; biota to sediment accumulation factor; fluxes; relative retention time; mass spectrometry; relative response factor; ultra-violet spectroscopy; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) have been assigned toxic equivalency factors (TEFs). These compounds are today routinely analysed with sophisticated analytical techniques. LÄS MER

  7. 20. Glaciodynamics, Deglacial Landforms and Isostatic Uplift during the last Deglaciation of Norrbotten, Sweden

    Författare :Mattias Lindén; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Sedimentology; Geologi; physical geography; Geology; glaciotectonic; thrust stacking; deforming bed; ribbed moraine; Niemisel moraine; De Geer moraine; isostatic uplift; glaciodynamics; deglaciation; klimatologi; kartografi; marklära; Fysisk geografi; geomorfologi; geomorphology; cartography; climatology; pedology;

    Sammanfattning : The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations.
