    Sammanfattning : In the production of paper, the quality of the pulp is an important factor both for the productivity and for the final quality. Reliable real-time measurements of pulp quality are therefore needed. LÄS MER

  3. 12. Non-Invasive Multidimensional Imaging Applied on Biological Substances

    Författare :Anders Kaestner; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave propagation; Tomography; Polarimetry; Frequency estimation; Anisotropic media; Wood; Muscles; Paper; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis presents the research and development of a microwave in-strument to capture tomographic information from the inner structure ofthe biological sample. The principle of the instrument is based on theanisotropy introduced by the fibres in materials such as wood and musclesin terms of information regarding changes in the fibre structure. LÄS MER

  4. 13. Characterisation of Atrial Electrophysiology with respect to Atrial Fibrillation - A Non-Invasive Approach

    Författare :Fredrik Holmqvist; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Atrial fibrillation; Human; Conduction; Signal; Spectral analysis; P wave morphology; Atrial remodelling; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Atrial fibrillation (AF) is the most common form of cardiac arrhythmia encountered in clinical practice, accounting. Recent findings highlight the need for better characterisation of the arrhythmia in each patient, in order to improve patient treatment. LÄS MER

  5. 14. 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

  7. 15. Non-invasive analysis of leukotrienes as biomarkers of airway inflammation : method development and clinical applications

    Författare :Flora Gaber; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Airway inflammation; aspirin-intolerant asthma; biomarker; exhaled breath condensate; FENO; induced sputum; leukotrienes; 5-lipoxygenase; non-invasive analysis; saliva;

    Sammanfattning : Asthma and chronic obstructive pulmonary disease (COPD) are two common diseases characterized by chronic airway inflammation, but the inflammation in asthma is different from the one in COPD. In addition, asthma is a heterogeneous disease presenting with many different phenotypes (e.g. LÄS MER
