  1. 1. Immunopathogenic aspects of resolving and progressing appendicitis

    Författare :Marie Rubér; Christina Ekerfelt; Roland Andersson; Gunnar Olaison; Johan Rönnelid; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Background: Appendicitis is one of the most common diseases requiringemergency surgical intervention. There are several indications that the diagnosisappendicitis harbours two different entities, one progressing to gangrene and perforation(advanced) and one that resolves spontaneously (phlegmonous).

  3. 2. An ultra-thin-walled superconducting solenoid for meson-decay physics

    Författare :Roger Ruber; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiologi; Radiology;

    Sammanfattning : A compact and extremely thin-walled superconducting warm-bore solenoid magnet, has been developed for the WASA detector setup at the CELSIUS accelerator and storage ring of the The Svedberg Laboratory. It provides a central axial magnetic field strength of 1. LÄS MER

  4. 3. From Macroscopic to Microscopic Dynamics of Superconducting Cavities

    Författare :Anirban Bhattacharyya; Vitaliy Goryashko; Volker Ziemann; Roger Ruber; Jean Delayen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superconducting cavity; superconductivity; self-excited loop; Ginzburg-landau; vortex; optimization; quality factor; microwave; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : Superconducting (SC) radio frequency (RF) cavities are at the heart of many large-scale particle accelerators such as the European Spallation Source (ESS), the X-ray Free Electron Laser (XFEL), the Linac Coherent Light Source (LCLS)-II and the proposed International Linear Collider (ILC). The SC cavities are essentially resonant structures with very high intrinsic quality factors (Q0) of the order of 1010. LÄS MER

  5. 4. Development of an analytic Beam Model with non-linear Space-Charge Forces and Envelope Stability Studies

    Författare :Michael Holz; Volker Ziemann; Roger Ruber; Mohammad Eshraqi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Space-charge—the repelling force of same-charged particles—is a major challenge in the development and application of high-current linear accelerators like spallation sources or accumulator rings. Understanding the dynamical behavior of the beam in its presence is imperative to prevent beam loss and subsequent detrimental effects. LÄS MER

  7. 5. Criticality of fast failures in the High Luminosity Large Hadron Collider

    Författare :Björn Lindström; Roger Ruber; Daniel Wollmann; Maja Olvegård; Annika Nordt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine protection; failures; beam losses; accelerator physics;

    Sammanfattning : Each of the two Large Hadron Collider (LHC) beams contain 362 MJ of energy. This will be further increased to 678 MJ in the upcoming upgrade to the High Luminosity LHC (HL-LHC). In the event of an uncontrolled beam loss, a significant hazard occurs, that can damage the machine components. LÄS MER
