  1. 1. Multicomponent diffusional reactions in tool steels Experiment and Theory

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Greta Lindwall; Malin Selleby; Karin Frisk; John Ågren; Carelyn Campbell; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot-work tool steel; precipitation hardening; DICTRA; coarsening; mobilities; CALPHAD; cobalt; PM tool stees; nitrogen; compound materials;

    Sammanfattning : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.

  3. 3. The Liberalization Experiment Understanding the political rationales leading to change in pharmacy policy

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Kristin Wisell; Sofia Kälvemark Sporrong; Marja Airaksinen; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacy policy; reregulation; liberalization; Sweden; pharmacist; pharmacy; Social Pharmacy; Samhällsfarmaci;

    Sammanfattning : In 2009, a pharmacy policy reform was introduced in Sweden whereby the state owned community pharmacy monopoly was abolished. As a result two thirds of the pharmacies were sold. As there were no longer restrictions on ownership and establishment, new pharmacies and new owners appeared. LÄS MER

  4. 4. Fatigue crack growth in fiber metal laminates : experiment and modeling

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Per Hofslagare; Michel van Tooren; [2004]

    Sammanfattning : Fiber Metal Laminates (FML) is a class of materials with highly resistant fatigue behavior, developed primary for the aerospace industry. The laminates are comprised of alternating layers of high strength aluminwn sheet and fiber reinforced polymers. LÄS MER

  5. 5. The measurement of chemical persistence in the field by benchmarking Theory and Experiment

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Hongyan Zou; Michael McLachlan; Keri Hornbuckle; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical benchmarking; persistence; half-lives; modeling; threshold benchmarking; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Persistence is one of the core criteria in chemical exposure and hazard assessment. It is often defined as the half-life for the removal of a chemical from a specified environment by transformation. Chemicals with long transformation half-lives may pose high risks for wildlife or humans and be subject to long-range transport to remote areas. LÄS MER
