  1. 1. Using genomics to improve Bacillus anthracis diagnostics and outbreak investigations

    Författare :Joakim Ågren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The bacterium Bacillus anthracis causes the disease anthrax, primarily in herbivores but many mammals are susceptible to the disease. Its infective form is as a dormant spore that can lie in the soil for decades. LÄS MER

  2. 2. De ofrälse och makten : En institutionell studie av riksdagen och de ofrälse ståndens politik i maktdelningsfrågor 1660-1682

    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Commoner Estates; Riksdag; 17th century; Priests; Burghers. Peasants; power. constitutionalism; patriarchal. institutions. organizations; historia; History;

    Sammanfattning : In this thesis the constitutional policies of the three Commoner Estates (Priests, Burghers and Peasants) of the Swedish Riksdag between the years 1660 and 1682 is examined. While many previous historians have focused on the power-struggle between the Crown and the nobility, the Commoner Estates have been presumed to be staunch supporters of absolutism. LÄS MER

  3. 3. ICME guided study of mass transport in production and application of cemented carbides

    Författare :Armin Salmasi; Henrik Larsson; Lars Höglund; Andreas Blomqvist; Joakim Odqvist; John Ågren; José Garcia; KTH; []

    Sammanfattning : Cemented carbides are metallic composites consisting of a WC hard phase and a ductile binder, usually Co-based, produced by powder metallurgy and sintering. Cemented carbides are an essential part of modern material and manufacturing processes. LÄS MER

  4. 4. Phase Separation in Stainless Steels Studied by Small-angle Neutron Scattering

    Författare :Xin Xu; Peter Hedström; Joakim Odqvist; John Ågren; Cristelle Pareige; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-Cr alloys; stainless steels; spinodal decomposition; phase separation; small-angle neutron scattering; mechanical properties; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Fe-Cr based steels, i.e. stainless steels, possessing a combination of excellent corrosion resistance and good mechanical properties, have indispensable applications ranging from low-end cooking utensils, to sophisticated components for nuclear power plants. LÄS MER

  5. 5. Experimental study of phase separation in Fe-Cr based alloys

    Författare :Jing Zhou; John Ågren; Joakim Odqvist; Peter Hedström; Andersson Marcus; KTH; []
    Nyckelord :Duplex stainless steels; Ferritic stainless steels; Spinodal decomposition; Phase separation; Atom probe tomography; Clustering; Radial distribution function RDF ;

    Sammanfattning : Duplex stainless steels (DSSs) are important engineering materials due to their combination of good mechanical properties and corrosion resistance. However, as a consequence of their ferrite content, DSSs are sensitive to the so-called ‘475°C embrittlement’, which is induced by phase separation, namely, the ferrite decomposed into Fe-rich ferrite (α) and Cr-rich ferrite (α'), respectively.
