  2. 1. Genetic control of myasthenia gravis : a study on cytokine and co-stimulator genes and their related functions

    Author : DeRen Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Myasthenia gravis (MG) is a classical autoimmune disease characterised by muscle weakness due to an immune attack against the nicotinic acetylcholine receptor (AchR) on the postsynaptic membrane of the neuromuscular junction. The aim of the study was to identify the role of the genes encoding potential immune components, such as TNF, IL-1, IL-1 receptor antagonist, IL-4, IL-10, and cytotoxic T lymphocyte antigen 4 (CTLA-4) in the pathogenesis of MG.

  4. 2. An anagram of the ideas of filmmaker Maya Deren : creative work in motion pictures

    Author : Moira Sullivan; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Deren; Maya; 1917-1961; Kvinnliga filmregissörer; Experimentfilm; USA;

    Abstract : Maya Deren’s corpus of work, which has been given various designations within the American avant-garde filmmaking practice of the 1940’s and 1950’s, will be analysed according to the biographical legend—an approach that focuses on authorship within the historical conditions of conception and reception. Influences on her theories in art and ethnography will be noted through several historical discourses: the French Symbolist Poets, Henri Bergson, Kurt Koffka, T. READ MORE

  5. 3. Properties of multilayered and multicomponent nitride alloys from first principles

    Author : Fei Wang; Ferenc Tasnadi; Igor Abrikosov; Frank Mücklich; Claudia Draxl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis is a theoretical exploration of properties of multilayered and multicomponent nitride alloys, in particular their mixing thermodynamics and elastic behaviors. Systematic investigation of properties of a large class of materials, such as the multicomponent nitride solid solutions, is in line with the modern approach of high-throughput search of novel materials.

  6. 4. Simulation Modelling of a Shift to Service-Based Offerings : Resource efficiency and operational implications in the context of the circular economy

    Author : Raphael Wasserbaur; Tomohiko Sakao; Erik Sundin; Steve Evans; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource efficiency; resource effectiveness; circular economy CE ; sociotechnical systems; systems thinking; simulation; product service system PSS ; system dynamics;

    Abstract : The unsustainable levels of resource use and emissions of our economies and their threat to future generations are core issues of our time. The circular economy (CE) conceptualises a different type of economy that is restorative and regenerative by design and aims to keep products, components and materials at their highest utility and value at all times, distinguishing between technical and biological cycles.

  7. 5. Industrial Alloys Studied by Surface Sensitive Techniques

    Author : Lisa Rullik; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminum alloy; brazing; AA 6063; duplex stainless steel; SAF 2507; XPS; APXPS; XPEEM; XRR; microstructure; aluminiumlegering; hårdlödning; AA 6063; duplexstål; SAF 2507; XPS; APXPS; XPEEM; XRR; mikrostruktur;

    Abstract : This thesis reports on surface studies of industrial materials whose importance for society manifests in the vast range of applications. In industrial materials alloying is performed in order to improve the parent material's physical and mechanical properties such as strength, corrosion and wear resistance, as well as high temperature performance in comparison to the pure metal.
