  1. 1. Ortnamnsanpassning som process : En undersökning av vendiska ortnamn och ortnamnsvarianter i Knýtlinga saga

    Författare :Alexandra Petrulevich; Henrik Williams; Staffan Nyström; Michael Lerche Nielsen; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; place-name replication; place-name adaptation; Old Norse; Knýtlinga saga; Wendish place-names; contact onomastics; philology; ortnamnsreplikation; ortnamnsanpassning; fornvästnordiska; Knýtlinga saga; vendiska ortnamn; kontaktonomastik; ortnamnsvariant; filologi; Pommern; vender; språkkontakt; polabiska; pomoranska; Nordiska språk; Scandinavian Languages;

    Sammanfattning : The aim of the thesis is to theoretically and empirically describe and explain the phenomenon of place-name adaptation which does not necessarily end with the borrowing or replication of place-names but can continue further. 48 Wendish place-names in Knýtlinga saga, including their attestations and variants in a selection of the saga’s text carriers and corresponding text witnesses, constitute the primary material for the investigation.

  3. 2. Progressives in use and contact : A descriptive, areal and typological study with special focus on selected Iranian languages

    Författare :Ghazaleh Vafaeian; Östen Dahl; Agnes Korn; Maria Koptjevskaja Tamm; Pier Marco Bertinetto; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; progressive; use; contact; areal; parallel corpora; typology; grammaticalization; Iranian; Persian; Mazandarani; Gilaki; Taleshi; Tati; Linguistics; lingvistik;

    Sammanfattning : Progressives are grammatical patterns primarily used to refer to events that are ongoing at a specific time. This thesis investigates uses of such patterns in a number of languages as well as the interaction of a number of progressives in contact. LÄS MER

  4. 3. Cam Roller Contact : Surfaces and Tribology

    Författare :Frédéric Cabanettes; Bengt-Göran Rosén; Ulf Olofsson; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wear reduction; camshaft; roller; surface topography; relocation; elasto plastic rough contact; elasto hydrodynamic lubrication; Mechanical engineering; Maskinteknik;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. In the valve train, mechanical components such as camshafts and rollers are defined by specifications including more and more constraints concerning their ability to face wear thus prolonging lifetime.

  5. 4. Wheel-rail contact modelling in vehicle dynamics simulation

    Författare :Matin Shahzamanian Sichani; Mats Berg; Roger Enblom; Elena Kabo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; non-elliptic contact; vehicle-track interaction; rail vehicle dynamics; rolling contact; MBS; virtual penetration; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Sammanfattning : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena. LÄS MER

  7. 5. The Plasma Contact System : New Functional Insights from a Hemostatic and Thrombotic Perspective

    Författare :Jennie Bäck; Bo Nilsson; Kristina Nilsson Ekdahl; Ulla Hedner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Contact activation; factor XII; platelets; coagulation; antithrombin; C1 inhibitor; hemostasis; biomarkers; vascular disease.; Klinisk immunologi; Clinical Immunology;

    Sammanfattning : The physiological role of the plasma contact system still remains a partial enigma. The aim of the presented work was to expand our understanding of the plasma contact system, focusing on its physiological activation and function, principally from a hemostatic perspective. It also explored contact system activation under pathological conditions. LÄS MER
