  1. 21. The Shape of Strangeness: Transverse Spherocity and Underlying Event studies of φ and its relation to Ξ in √s = 13 TeV pp collisions

    Författare :Adrian Nassirpour; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ALICE; Quark-Gluon Plasma; small systems; pp collisions; underlying event; event-shape engineering; transverse activity; strangeness enhancement; resonance production; Fysicumarkivet A:2022:Nassirpour;

    Sammanfattning : Through ultrarelativistic particle collisions at the LHC, it is possible to deconfine quarks and gluons. This deconfinement gives rise to a strongly interacting medium, referred to as the Quark-Gluon Plasma (QGP). LÄS MER

  3. 22. Optimizing computed tomography : quality assurance, radiation dose and contrast media

    Författare :Patrik Nowik; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). LÄS MER

  4. 23. Heat Transfer Enhancement of Latent Thermal Energy Storage in Rectangular Components

    Författare :Amir Abdi; Viktoria Martin; Justin NingWei Chiu; Mohammed Farid; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : Latent Thermal Energy Storage (LTES) is an interesting choice to storethermal energy in a sustainable energy system. The primary benefit of LTESis the relatively high latent heat of fusion of the materials, known as PhaseChange Materials (PCM), used in such a system as the storage medium. LÄS MER

  5. 24. Magnetic Resonance Imaging of the Hepatobiliary System Using Hepatocyte-Specific Contrast Media

    Författare :Nils Dahlström; Örjan Smedby; Torkel Brismar; Anders Ynnerman; Lennart Blomqvist; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostic radiology; Diagnostisk radiologi;

    Sammanfattning : There are two Gadolinium-based liver-specific contrast media for Magnetic Resonance Imaging on the market, Gd-BOPTA (MultiHance®, Bracco Imaging, Milan, Italy) and Gd-EOB-DTPA (Primovist®, Bayer Schering Pharma, Berlin, Germany). The aim of this study in two parts was to evaluate the dynamics of biliary, parenchymal and vascular enhancement using these contrast media in healthy subjects. LÄS MER

  7. 25. Investigation of nanoparticle-cell interactions for development of next generation of biocompatible MRI contrast agents

    Författare :Natalia Abrikossova; Kajsa Uvdal; Caroline Brommesson; Eva Särndahl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Progress in synthesis technologies and advances in fundamental understanding of materials with low dimensionality has led to the birth of a new scientific field, nanoscience, and to strong expectations of multiple applications of nanomaterials. The physical properties of small particles are unique, bridging the gap between atoms and molecules, on one side, and bulk materials on the other side. LÄS MER
