  1. 1. Tailored Properties of Ferromagnetic Thin Films

    Författare :Peter Warnicke; Peter Svedlindh; Peter Grünberg; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; micromagnetics; domain wall; vortex; pinning potential; nanowire; spin dynamics; spin transfer torque; magnetic anisotropy; MFM; Permalloy; PMA; magnetic multilayer; Curie temperature; DMS; GaMnAs; magnetic bioseparation; Engineering physics; Teknisk fysik;

    Sammanfattning : Magnetic thin films and patterned nanostructures have been studied with respect to their magnetic properties using SQUID-magnetometry, magnetic force microscopy, electrical measurements, and micromagnetic calculations. Properties of vortex domain walls, trapped in Permalloy nanowires with artificial constrictions, were investigated experimentally and by numerical calculations. LÄS MER

  2. 2. Homogenization of some partial differential operators and integral functionals

    Författare :Peter Wall; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis is devoted to some problems connected to the theory of homogenization of partial differential operators and integral functionals. The thesis consists of an introduction and three different parts, A-C. In the introduction we give an elementary presentation of the basic ideas in the homogenization theory. LÄS MER

  4. 4. EU-undervisning : En jämförelse av undervisning om politik på nationell och europeisk nivå

    Författare :Peter Wall; Hans Lödén; Malin Stegmann-McCallion; Lee Miles; Cecilia Arensmeier; Karlstads universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Curriculum studies; EU; Swedish National Politics; Civics; Lower Secondary Education; Subject didactics; Ämnesdidaktik; Statsvetenskap; Political Science;

    Sammanfattning : This study focuses on, and explores the curriculum content and resources used when teaching on the European Union (EU) and EU-questions within civics education at lower secondary level in Sweden. The research findings have been examined from a ‘best practice’ perspective in relation to subject matter which is seen as positive in the context of political participation. LÄS MER

  5. 5. New methods for optimization of mechanical ventilation

    Författare :Peter Kostic; Peter Frykholm; Anders Larsson; Johan Petersson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mechanical ventilation; optoelectronic plethysmography; forced oscillation technique; laser interferometry; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Mechanical ventilation saves lives, but it is an intervention fraught with the potential for serious complications. Prevention of these complications has become the focus of research and critical care in the last twenty years. LÄS MER
