  1. 1. Three Pion Interferometry in the NA44 Experiment

    Författare :Janus Schmidt-Sörensen; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; heavy-ion physics; bose-einstein; Elementary particle physics; interferometry; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1999:Schmidt-Sörensen;

    Sammanfattning : This thesis presents a three-particle correlation analysis with pions originating from Sulphur-Lead and Lead-Lead collisions at 200 and 158 GeV/c per nucleon respectively, taken by the CERN heavy-ion experiment NA44. The genuine three-body correlation is suppressed in both colliding systems which indicates that the particle production source is partly coherent. LÄS MER

  3. 2. Molecular epidemiology approach : nested case-control studies in glioma and lymphoid malignancies

    Författare :Florentin Späth; Beatrice S. Melin; Carl Wibom; Ann Sofie Johansson; Ingvar Bergdahl; Ola Landgren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; B cell lymphoma; multiple myeloma; risk; repeated samples; prospective longitudinal study; nested case-control study; circulating sEGFR and sERBB2; circulating immune markers and growth factors; marker disease association; disease progression; NSHDS; Janus; linear mixed modeling; epidemiologi; Epidemiology; Oncology; onkologi;

    Sammanfattning : BACKGROUND: Nested case-control studies aim to link molecular markers with a certain outcome. Repeated prediagnostic samples may improve the evaluation of marker-disease associations. However, data regarding the benefit of repeated samples in such studies are sparse. LÄS MER

  4. 3. Viljan att vara reko : biopolitik och professionsetik – rehabkoordineringens janusansikte

    Författare :Ulrika Flädjemark; Tuija Muhonen; Stig Westerdahl; Daniel Nyberg; Niklas Altermark; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; rehabilitation coordinator; biopolitics; governmentality; dispositive analysis; organizational subjectivity; insurance medicine; rehabiliteringskoordinator; biopolitik; governmentality; dispositiv analys; organisatorisk subjektivitet; försäkringsmedicin; Urban studies; Urbana studier;

    Sammanfattning : Rehabiliteringskoordinator (reko) har tillkommit som en ny, lagstadgad funktion i linje med att göra arbetsåtergång för sjukskrivna ett prioriterat område inom vården. Reko har som uppgift att stödja patienten, samordna den interna organiseringen i sjukskrivningsprocessen samt samverka med externa aktörer; såsom arbetsgivare och Försäkringskassans handläggare.

  5. 4. Aerosol Synthesis and Characterization of Heterogeneous Bimetallic Nanoparticles

    Författare :Markus Snellman; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; core-shell; Janus nanoparticles; aerosol technology; Fysicumarkivet A:2023 Snellman; Nanopartiklar; kärna-skal; Januspartiklar; aerosolteknologi;

    Sammanfattning : As the proverbial noose tightens around humanity’s resource spending, research is focused on utilizing materials to their fullest potential. Nanotechnology is the ultimate way to economize by splitting objects into smaller parts and dispersing the material properties over greater surface to volume ratios. LÄS MER

  7. 5. Aerosol Generated Core-shell Nanoparticles : Synthesis and Characterization

    Författare :Markus Snellman; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerosol technology; core-shell particles; nanoparticles; Janus particles;

    Sammanfattning : Aerosol technology is a promising platform to synthesize and study core-shellnanoparticles - a multi-elemental nanoparticle system where the core of one material is covered by a shell of another material. In this thesis, two distinctly separate strategies have been explored to synthesize core-shell nanoparticles by aerosol methods: physical vapor deposition (PVD) by evaporation, and surface segregation via thermal treatment.
