  2. 1. Delayed and cancelled orthopaedic surgery; Causes and consequences

    Author : Ulla Caesar; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Appointments and schedules; Operating rooms organisation and administration; Waiting list; Cancelled surgery; Orthopaedic surgery; Delayed surgery; Perioperative nursing; Phenomenological Hemeneutics Method; Social rejaction; Shame; Appointments and schedules;

    Abstract : Extended waiting time, over-booked waiting lists and cancelled and delayed surgical procedures are realities for some patients treated at orthopaedic clinics in Sweden. This situation affects the prioritisation procedures for both emergency and elective surgery and results in even longer waiting lists, not only for planned patients, but for emergencies as well.

  4. 2. Thermodynamic and kinetic investigation of systems related to lightweight steels

    Author : Weisen Zheng; Malin Selleby; Tomás Gómez-Acebo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-Mn-Al-C; CALPHAD; MGI; ICME; Precipitation strengthening; Lightweight steels.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Lightweight steels have attracted considerable interest for automobile applications due to the weight reduction without loss of high strength and with retained excellent plasticity. In austenitic Fe-Mn-Al-C steels, the nano-precipitation of the κ-carbide within the austenitic matrix significantly contributes to the increase in yield strength. READ MORE

  5. 3. Theoretical Atomic Spectroscopy of Earthbound and Stellar Plasma

    Author : Jon Grumer; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; atomstruktur; atomära processer; elektronkorrelation; plasmaspektroskopi; magnetfält; hyperfinstruktur; solkoronan; rymdväder; förekomst av grundämnen i stjärnor; datorsimuleringar; Zeemaneffekt; relativistiska effekter; atomic structure; atomic processes; computer simulation; electron correlation; relativistic atomic theory; plasma spectroscopy; Zeeman effect; magnetic fields; hyperfine structure; solar corona; space weather; stellar abundances; Fysicumarkivet A:2016:Grumer;

    Abstract : Motivated by spectroscopic analysis of astrophysical and laboratory plasma, this thesis concerns the fundamental structure and spectral properties of atoms and their ions. The multiconfiguration Dirac-Hartree-Fock (MCDHF) method is used to predict the emission or absorption of radiation, by atomic systems in general, and of heavy and highly charged ions in particular.

  6. 4. A Stacked Prism Lens Concept for Next-Generation Hard X-Ray Telescopes

    Author : Wujun Mi; Mats Danielsson; Peter Nillius; Ralf K. Heilmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; focusing X-ray telescopes; Wolter-I optics; stacked prism lens; focused UV lithography; grayscale e-beam lithography; proximity effect correction; angular resolution; effective collecting area; röntgenteleskop; Wolter-I-optik; staplade prismalinser; fokuserad UV-litografi; elektronstråle-litografi; Fysik; Physics;

    Abstract : Over the past half century, the focusing X-ray telescope has played a very prominent role in X-ray astronomy at the frontier of fundamental physics. The finer angular resolution and increased effective area have enabled more and more exciting discoveries and detailed studies of the high-energy universe, including the cosmic X-ray background (CXB) radiation, black holes in active galactic nuclei (AGN), galaxy clusters, supernova remnants, and so on.

  7. 5. Study of precipitation in martensitic Fe-C-Cr alloys during tempering : Experiments and modelling

    Author : Ziyong Hou; Joakim Odqvist; Andersson Jörgen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-C-Cr alloy; Microstructure; Precipitates; Tempering of martensite; Electron microscopy; Modelling.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. READ MORE
