  1. 1. Calibration and quality assessment of DESCARTES : grabsampler for stratospheric tracers

    Författare :Johan Arvelius; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorption; Balloon; Carboxen; CFC; Chloro-Fluoro Carbon; Grab sampling; Halocarbon; Molecular sieve; Stratospheric tracer; Tracer; Adsorption; Ballong; Carboxen; CFC; Halogeniserade kolväten; Klor-Flourkarbon; Spårgas; Stratosfärisk spårgas; Space physics; Rymdfysik;

    Sammanfattning : DESCARTES is a light-weight, balloon-borne grab sampler for stratospheric long-lived tracers developed at the University of Cambridge. 33 flights have been performed with two versions of the instrument at northern latitudes by the DESCARTES team at the Swedish Institute of Space Physics (IRF) in Kiruna during the years 1997-2000.

  2. 2. Prevention of intimal hyperplasia after balloon angioplasty and / or stent insertion. or How to mend a broken heart - Just say NO

    Författare :Jan Harnek; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Remodeling. Endothelium-derived factors. Self-expanding stents. Restenosis. Scanning -electron microscopy. Endothelial factors. Nitric oxide. Intimal hyperplasia. Angioplasty. Stents. Interventional procedures. Endothelium.;

    Sammanfattning : Background: Restenosis is the most frequently occurring adverse event after percutaneous intravascular treatment of atherosclerotic lesions, which limits long-term patency of the intervention. Objective: The aim of the study was to evaluate if minimizing vascular injury during treatment by insertion of self-expanding stents or modifying the reparative mechanisms by local drug delivery can reduce restenosis.

  3. 3. Att föra det egna till torgs : berättande, stoff och samtid i Kerstin Strandbergs, Enel Melbergs och Eva Adolfssons debutromaner

    Författare :Immi Lundin; Litteraturvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; Eva Adolfsson; Enel Melberg; Kerstin Strandberg; 1970 s and 1980 s; Public Dialog in Sweden 1960 s; Contextualization; Focalization; First Novels; Close Reading; Feminist Narratology;

    Sammanfattning : The Swedish debate both on the role of literature and on the social position of women underwent rapid change during the thirty years from 1960 to 1990. In Bringing the Personal to Market: Narrative, Subject-Matter and Contemporary History in the First Novels of Kerstin Strandberg, Enel Melberg and Eva Adolfsson, the debut novels of three female authors’ are close-read from a thematic and narratological perspective.

  4. 4. Physical Aspects of Thermotherapy - A study of heat transport with a view to treatment optimisation

    Författare :Johan Olsrud; Sektion V; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance; non-invasive; temperature; coagulation; prostatic; menorrhagia; liver tumour; finite element method FEM ; thermal conductivity; intracavitary; interstitial; laser; Thermotherapy; hyperthermia; MRI; Medicine human and vertebrates ; Medicin människa och djur ; Physics; Fysik; Fysicumarkivet A:1998:Olsrud;

    Sammanfattning : Local treatment with the aim to destruct tissue by heating (thermotherapy) may in some cases be an alternative or complement to surgical methods, and has gained increased interest during the last decade. The major advantage of these, often minimally-invasive methods, is that the disease can be controlled with reduced treatment trauma and complications. LÄS MER

  5. 5. Thermal endometrial destruction by means of a balloon catheter : experimental and clinical evaluation of a new form of treatment for menorrhagia

    Författare :Britt Friberg; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrologi; Obstetrik; gynekologi; sexuality; gynaecology; andrology; reproduction; Obstetrics; balloon catheter; thermal coagulation; Menorrhagia; endometrial destruction; saline infusion sonography; uterine thermal conductivity; reproduktion; sexualitet;

    Sammanfattning : Thermal endometrial destruction by means of a silicone balloon catheter is a new form of treatment for menorrhagia aimed at reducing menstrual blood loss. The purpose of the present work was to study, experimentally, the thermal effects on and the thermal conductivity of uterine tissue, to obtain a basis for the estimation of optimal treatment conditions by means of numerical analyses using a computer simulation model, to elucidate possible problems which may arise during the procedure, to evaluate how the patients tolerated this treatment and to judge which patients were suitable for this form of treatment and, finally, to study the uterine cavity after treatment and the long-term results of treatment.
