    Author : Joakim Hirvonen Grytzelius; Lars Johansson; Hanmin Zhang; Leif Johansson; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiconductor surfaces; Si 111 ; Ge 111 ; manganese; Mn; silicides; germanides; atomic structure; electronic structure; magnetic properties; LEED; ARPES; XPS; core-level spectroscopy; STM; STS; XMCD; Physics; Fysik;

    Abstract : The research presented in this thesis concerns experimental studies of thin manganese silicide and germanide layers, grown by solid phase epitaxy on the Si(111)7×7 and the Ge(111)c(2×8) surfaces, respectively. The atomic and electronic structures, as well as growth modes of the epitaxial Mn-Si and Mn-Ge layers, were investigated by low-energy electron diffraction (LEED), angle-resolved photoelectron spectroscopy (ARPES), core-level spectroscopy (CLS), and scanning tunneling microscopy and spectroscopy (STM and STS).

    Keywords : ARDS; azurocidin; burn; CAP-37; critical care; granulocyte; HBP; histamine; intensive care; leucocyte; leukocyte; mediator; methylhistamine; MOF; oedema; neutrophil; permeability; PMN; trauma; vascular permeability;

    Abstract : Background: Our innate immunesystem protects us from infections but, since its methods is not all specific for microorganisms, may also induce collateral damage.Severe physical injury often proved deadly throughout evolution. Such injuries may induce massive collateral damage. READ MORE

  5. 3. High strain rate deformation of Alloy 718

    Author : Joakim Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Split-Hopkinson; Alloy 718; Johnson-Cook;

    Abstract : Alloy 718 is a high temperature alloy, used where high temperature strength or oxidation resistance is required. As the alloy is precipitate heat treatable it is possible to have a large variety of strength depending on microstructure. READ MORE

  6. 4. High strain rate deformation of Alloy 718, Influence of Microstructure on Mechanical Properties

    Author : Joakim Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Adiabatic shear localisation; Split-Hopkinson; Johnson-Cook;

    Abstract : Alloy 718 is a high temperature alloy, used where high temperature strength or oxidation resistance is required. As the alloy is precipitate heat treatable, it is possible to have a large variety of deformation and mechanical properties depending on microstructure. READ MORE

  7. 5. Why don’t we mine the landfills?

    Author : Nils Johansson; Joakim Krook; Mats Eklund; Peter Tom Jones; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : There are many reasons to mine landfills. For example, metals are increasingly shifting location from the Earth’s crust through human society into landfills. READ MORE
