  1. 1. The Columnar Lined Esophagus. Pathophysiological and Clinical Aspects

    Detta är en avhandling från Department of Surgery and Gastroenterology, Lund University Hospital, SE-221 85 Lund, Sweden

    Författare :Stefan Öberg; Lund University.; Lunds universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intestinal metaplasia; Barrett s esophagus; Esophageal columnar metaplasia; Metaplasia; Pathophysiology; Gastroesophageal reflux disease; Esophagus; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : There is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction.

  2. 2. The Swedish Knee Arthroplasty study with special reference to unicompartmental prostheses

    Detta är en avhandling från Department of Orthopaedics, Lund University

    Författare :Stefan Lewold; Lund University.; Lunds universitet.; [1997]

    Sammanfattning : The Swedish Knee Arthroplasty study has prospectively registered and followed knee arthroplasties done in Sweden since 1976. Demography, epidemiology and general knee prosthetic biofunction is given for 30,003 primary knee arthro-plasties and their revisions through 1992. LÄS MER

  3. 3. Development and evaluation of an independent system for absorbed dose calculations in radiotherapy

    Detta är en avhandling från Stefan Johnsson (request by e-mail)

    Författare :Stefan Johnsson; Lund University.; Lunds universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; tomography; medical instrumentation; radiology; Clinical physics; cancer; Cytologi; onkologi; cancerology; oncology; Cytology; PDA; mini-phantom; in-air equivalence; primary kerma; transmission measurement; stopping power ratio; entrance dose; beam quality; quality control; error prevention; monitor unit calculation; radiation therapy; dose calculation;

    Sammanfattning : The aim of this work was to develop, implement and evaluate an independent system with which to calculate the absorbed dose, delivered by high-energy X-ray beams, to the prescription point and the depth of dose maximum. The introduction of such a system in the clinical routine may help ensure high-quality treatment and avoidance of errors which may jeopardise the clinical outcome of the treatment (i. LÄS MER

  4. 4. Metaphors and Norms - Understanding Copyright Law in a Digital Society

    Detta är en avhandling från Lund University

    Författare :Stefan Larsson; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2011]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; IPRED; copyright; file sharing; conceptual metaphor theory; path dependence; skeumorphs; conceptions; Norms; metaphors; InfoSoc; online anonymity; digital society.;

    Sammanfattning : This is a compilation thesis in the sociology of law, which analyses copyright law in three steps; the legal norms, the social norms and the underlying conceptions in their metaphorical representation. These three steps assist in answering the overarching question: "How do legal and social norms relate to each other in terms of the conceptions from which they emanate or by which they are constructed, and what is the role played by the explicit metaphors that express these norms?" The thesis shows how the development of copyright in Europe, when faced with the digital challenge, has been resiliently path dependent (Infosoc, IPRED and more). LÄS MER

  5. 5. Molecular mechanisms and complete antigen formation in allergic contact dermatitis

    Detta är en avhandling från Department of Clinical Sciences, Lund University

    Författare :Stefan Ahlfors; Lund University.; Lunds universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypersensitivity; adduct; immune response.; Allergy; hapten;

    Sammanfattning : Allergic contact dermatitis (ACD) is a common T cell mediated skin disease. Small reactive organic molecules called haptens induce ACD. Haptens are not recognized by themselves, but need to bond to endogenous proteins in the skin, and processed further into complete antigens. Antigen specific T cells then recognize the resulting antigen. LÄS MER
