    Nyckelord :Nuclear physics; fission gas release; nuclear fuel; core physics; gamma-ray spectroscopy; LOKET; thermal power; burnup; fuel failure; validation; cladding; Kärnfysik;

    Sammanfattning : Presently there is a clear trend of increasing demands on in-pile performance of nuclear fuel. Higher target burnups, part length rods and various fuel additives are some examples of this trend. LÄS MER

  4. 3. PET in Heart Failure - Methods and Applications

    Författare :Jens Sörensen; Göran Hedenstierna; Elisabeth Ståhle; Bengt Långström; Juhani Knuuti; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; congestive heart failure; myocardial ischemia; positron emission tomography; left ventricular dysfunction; tracer kinetic models; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : Positron Emission Tomography (PET) permits regional myocardial perfusion, fibrosis and oxidative metabolism to be non-invasively quantified with radioactive tracers such as [15O]-water and [1-11C]-acetate. PET is an established research tool in congestive heart failure (CHF), a major cause of morbidity and mortality. LÄS MER

  5. 4. Failure prediction of orthotropic Non-Crimp Fabric reinforced composite materials

    Författare :Henrik Molker; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Orthotropic; Non crimp-fabric; Failure initiation; Design methodology; Carbon fibre composite;

    Sammanfattning : The automotive industry needs to reduce the energy consumption to decrease the impact on the environment. One part of this is to reduce the weight of cars, thereby reducing the fuel consumption. A promising way to be successful with this is to introduce carbon fibre composites in the structural parts.

  7. 5. Modelling of Forming and Welding in Alloy 718

    Författare :Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forming; welding; Alloy 718; damage; GISSMO; failure; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry due to major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the vehicle’s weight while increasing engine's efficiency. LÄS MER
