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

    Author : Greta Lindwall; Malin Selleby; Karin Frisk; John Ågren; Carelyn Campbell; KTH; []
    Keywords : hot-work tool steel; precipitation hardening; DICTRA; coarsening; mobilities; CALPHAD; cobalt; PM tool stees; nitrogen; compound materials;

    Abstract : 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.

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

    Author : Per Hofslagare; Michel van Tooren; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. READ MORE

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

    Author : Kristin Wisell; Sofia Kälvemark Sporrong; Marja Airaksinen; Uppsala universitet; []
    Keywords : pharmacy policy; reregulation; liberalization; Sweden; pharmacist; pharmacy; Social Pharmacy; Samhällsfarmaci;

    Abstract : 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. READ MORE

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

    Author : Hongyan Zou; Michael McLachlan; Keri Hornbuckle; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; chemical benchmarking; persistence; half-lives; modeling; threshold benchmarking; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : 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. READ MORE

  5. 5. Viscoelastic Materials : Identification and Experiment Design

    Author : Agnes Rensfelt; Torsten Söderström; Händel Peter; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viscoelastic materials; complex modulus; system identification; optimal experiment design; distributed parameter systems; frequency domain identification; wave propagation; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Viscoelastic materials can today be found in a wide range of practical applications. In order to make efficient use of these materials in construction, it is of importance to know how they behave when subjected to dynamic load. READ MORE
