  2. 21. Molecular aspects of post-Chornobyl and sporadic papillary thyroid carcinoma

    Author : Andrii Dinets; Karolinska Institutet; Karolinska Institutet; []
    Keywords : papillary thyroid carcinoma;

    Abstract : Papillary thyroid carcinoma (PTC) exhibits various molecular abnormalities, both when sporadic and radiation-related. PTC is still diagnosed in adult individuals who were younger than 18 years at the time of the Chornobyl accident in 1986 and lived within the contaminated area. READ MORE

  4. 22. Signal processing applied to acoustic distance estimation and sound classification

    Author : Lennart Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : The thesis treats some signal processing applications to retrieval of information from acoustic measurements. In the distance estimation applications (parts AI, A2, B and C) an acoustic signal propagates through a physical system and is modified according to some system parameter. READ MORE

  5. 23. Clinical aspects of arterial wall stiffness with a focus on abdominal aortic aneurysm

    Author : Ida Åström Malm; Peter Blomstrand; Rachel De Basso; Niclas Bjarnegård; Per Lindqvist; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arterial Stiffness; Pulse Wave Velocity; Abdominal Aortic Aneurysm; Left Ventricle Function; Interleukin 10;

    Abstract : Background: Cardiovascular diseases are the most common type of age-related diseases and can affect health in several ways. As a result of increased life expectancy around the world, the prevalence of cardiovascular diseases is expected to increase. READ MORE

  6. 24. Assessment of Long-Term Losses in Prestressed Concrete Structures - Application for Nuclear Reactor Containments

    Author : Peter Lundqvist; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; KstrConcrete; Nuclear reactor containments; prestressed concrete; prestress losses; bonded tendons; creep; shrinkage; relaxation; prediction models; resonance frequency; acoustoelasticity.;

    Abstract : Most nuclear reactors, both in Sweden and worldwide, are enclosed by a prestressed concrete containment. The main purpose of the containment is to prevent any radioactive discharge to the environment in the event of a major internal accident. READ MORE

  7. 25. The right ventricle in volume or pressure overload : Insights from novel imaging techniques

    Author : Aleksandra Trzebiatowska-Krzynska; Eva Swahn; Niels Erik Nielsen; Lars Wallby; Marcus Carlsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : This study is inspired by the gap in knowledge regarding the timing of cardiac surgery and interventions in adult patients with congenital heart disease. There are many parameters used assessing right ventricular function; however, most of them have pitfalls. READ MORE
