  1. 1. Klädd Krigare : Skifte i skandinaviskt dräktskick kring år 1000

    Författare :Annika Larsson; Anne-Sofie Gräslund; Svante Norr; Lise Bender Jorgenssen; Uppsala universitet; []
    Nyckelord :Archaeology; warrior; viking age; armour; rigsthula; bayeux tapestry; birka; coin; sigtuna; runic; baptism; rus; khazar; metal wire; textile; christianisation; silk road; canute the great; mercenaries; trade route; dresscode; virtuous woman; kingship; frisian cloth; Arkeologi;

    Sammanfattning : Using textiles as clues, it is shown that, like in the rest of Scandinavia, there is a legible societal shift in favour of a new Christian organization as early as around year 1000 even in the central parts of what is now Sweden, including the, according to Adam of Bremen, “pagan” Mälar valley. During a period of at least a hundred and fifty years, the Mälar valley with Birka in the centre had enjoyed eastern trade, which is reflected in the rich finds of oriental textile fragments in the Birka graves.

  3. 2. Interaction of Cylindrical Penetrators with Ceramic and Electromagnetic Armour

    Författare :Lars Westerling; Kristofer Gamstedt; Bengt Lundberg; Nils G. Ohlson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Sammanfattning : Armoured vehicles have traditionally used steel armour as protection against penetrators such as projectiles and shaped charge jets. The latter produce a thin stretching metal jet, usually of copper, with a tip velocity of about 7-8 km/s. LÄS MER

  4. 3. Interaction between High-velocity Penetrators and Moving Armour Components

    Författare :Ewa Lidén; Bengt Lundberg; Hevré Couque; Uppsala universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Sammanfattning : This work was aimed at understanding mechanisms of importance for the design of weight-efficient armour against long-rod projectiles (LRP) and shaped charge (SC) warheads. The focus was on how to achieve effective mechanical disturbances on the threat before it hits the target. LÄS MER

    Sammanfattning : This thesis is about industrial heritage—the protection of ferrous heritage by using anticorrosive oil varnish paints. The purpose of this thesis in Kulturvård and craft research is to provide guidelines, tools, concepts, and models that may be used in anticorrosive oil varnish painting maintenance of ferrous heritage.
