    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Proximity Extension Assay; Precision medicine; Assay development; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : Precision medicine aims to utilise biomarkers to ensure the right treatment is given to the right patient at the right time. In pursuit of this goal, sensitive protein detection is essential to improve opportunities for discovery, verification, validation and development of valuable protein biomarkers. LÄS MER

  4. 3. Uncovering Magnetic Order in Nanostructured Disordered Materials : A Study of Amorphous Magnetic Layered Structures

    Författare :Panagiotis Korelis; Björgvin Hjörvarsson; Gabriella Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amorphous Materials; Magnetism; Amorphous Magnetism; Magnetic Measurements; Thin Films; Multilayers; Thin Film Deposition; Sputtering; FeZr Alloys; AlZr Alloys; X-ray Diffraction; Rutherford Backscattering Spectrometry; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : The scope of this thesis is the study of the interplay between structure and magnetism in amorphous materials. The investigations focus on the growth of amorphous layers and the study of the influence of structural disorder and reduced physical extension on the magnetic properties of thin films and multilayers.

  5. 4. Geometric discretization for incompressible magnetohydrodynamics on the sphere

    Författare :Michael Roop; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lie-Poisson structure; magnetohydrodynamics; Hamiltonian dynamics; magnetic extension; Casimirs; symplectic Runge-Kutta integrators;

    Sammanfattning : Many physical processes are modelled by partial differential equations (PDE), and their efficient discretization is still a challenging problem and an actively developing field. An important class of models arising in mathematical physics represents PDEs formulated in terms of a Lie-Poisson structure on the dual of infinite-dimensional Lie algebras, such as the Lie algebra of vector fields.

  7. 5. Magnetic Resonance Imaging in Legg-Calvé-Perthes Disease

    Författare :Peter Hochbergs; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; Histology; Metaphysis; Synovitis; Necrosis; Osteotomy; Arthrography; Magnetic Resonance Imaging; Legg-Calvé-Perthes Disease; Pediatrics; Hip; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology;

    Sammanfattning : The aims of this study were: to compare the cartilaginous outline of the femoral head obtained on arthrograms with those on MR images and to correlate it to the bony head outlines on conventional radiograps; to study early, postoperative cartilaginous and bony remodeling of the femoral head, after proximal femoral varus derotation extension osteotomy, with MR imaging and conventional radiography; to describe signal abnormalities on MR images in the femoral epiphysis, their location, extent and restitution over time; to evaluate the degree and persistence of synovitis in the hip joint by MR imaging; to analyze the metaphyseal histology and to correlate it to the signal intensity on the MR images in the corresponding biopsy region. Results and conclusions: MR imaging and arthrography define the shape of the femoral head cartilage equally well. LÄS MER
