    Abstract : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. READ MORE

  3. 3. Quaternary paleoceanography of the Arctic Ocean : A study of sediment stratigraphy and physical properties

    Author : Emma Sellén; Martin Jakobsson; Jan Backman; Dorthe Klitgaard-Kristensen; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Arctic Ocean; sedimentology; Quaternary; stratigraphy; physical properties; Earth sciences; Geovetenskap; Quaternary geology; Kvartärgeologi; Sedimentology; Sedimentologi; Marine Geoscience; marin geovetenskap;

    Abstract : A Quaternary perspective on the paleoceanographic evolution of the central Arctic Ocean has been obtained in this PhD thesis by studying sediment cores from all of the Arctic’s major submarine ridges and plateaus. The included cores were mainly recovered during the Healy-Oden Trans-Arctic expedition in 2005 and the Lomonosov Ridge off Greenland expedition in 2007. READ MORE

  5. 5. Physical properties of chromospheric features : Plage, peacock jets, and calibrating it all

    Author : Alexander G. M. Pietrow; Dan Kiselman; Jaime de la Cruz Rodríguez; Malcolm Druett; Gianna Cauzzi; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Sun; chromosphere; plage; jets; imaging; spectropolarimetry; Astronomy; astronomi;

    Abstract : The chromosphere is a complex and dynamic layer of the solar atmosphere, largely dominated by the local magnetic field configuration. It acts as an important interface between the photosphere below it and the hot corona above. However, studying this layer is not straightforward, as it is largely transparent in optical wavelengths.
