  1. 1. Inhibition of phagocyte signaling by the Yersinia virulence protein YopH

    Författare :Kerstin Andersson; Kerstin Andersson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Yersinia pseudotuberculosis evades the immediate immune defense of a host organism by inhibiting bactericidal functions of phagocytes, including phagocytosis, cytokine release, and the oxidative burst. Consequently, this pathogen can survive and multiply in lymphatic tissues. An ensemble of proteins called Yops are involved in the virulence of Y. LÄS MER

  3. 2. Effects of composition and the production process on formability of austenitic stainless steels

    Författare :Roger Andersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : Formability of austenitic stainless steels is strongly influenced by the chemical composition, the internal texture and the deformation conditions. The purpose of this study is to determine how small variations in chemical composition and minor variations in the production process are influencing the formability of type 304 and 316 austenitic stainless steels.

  5. 4. The Common Thread, Textile Production during the Late Iron Age and Viking Age

    Författare :Eva Andersson; Arkeologi; []
    Nyckelord :HUMANIORA; HUMANITIES; Haithabu; Birka; Scania; Viking Age; Late Iron Age; household production; textile valuables; sail cloth; bone needle; loom weight; textile production; spindle whorl; Archaeology; Arkeologi;

    Sammanfattning : The initial aim of the present PhD thesis was to develop the method of classification for textile tools to facilitate the study of textile production in an archaeological context. The thesis consists of five separate projects and a concluding summary. The study covers the late Iron Age, mainly the Viking Period. LÄS MER

  7. 5. Lindström quantifiers and higher-order notions on finite structures

    Författare :Anders Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Finite model theory; generalized quantifiers; higher-order quantifiers and operators; bijective Ehrenfeucht-Fraïssé games; quantifying over quantifiers; isomorphism quantifiers; MATEMATIK; MATHEMATICS; MATEMATIK; matematisk logik; Mathematical Logic;

    Sammanfattning : The expressive power of first-order logic is very limited on finite structures. One important way to obtain stronger logics is to add Lindström quantifiers, and another is to add higher-order quantification. We investigate two different ways of combing the two approaches. LÄS MER
