  1. 1. Insights in paper and paperboard performance by fiber network micromechanics

    Författare :August Brandberg; Artem Kulachenko; Sören Östlund; Carl Dahlberg; Rami Mansour; Kristofer Gamstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Fiber networks are ubiquitous due to their low cost and high ratio of mechanical performance to weight. Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (board). Often the ideal product is both mechanically sturdy and possible to print on.

  3. 2. Micro-mechanical characterization and modeling of paper and paperboard

    Författare :August Brandberg; Artem Kulachenko; Sören Östlund; Carl Dahlberg; Rami Mansour; Ron Peerlings; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (paperboard). This thesis investigates the mechanical performance of paper and paperboard via micro-mechanical modeling and presents new methods for the mechanical characterization of the micro scale, necessary in such models.

  4. 3. Computed Tomography and Magnetic Resonance Imaging in Determination of Human Body Composition. Methodological and Applied Studies

    Författare :John Brandberg; Göteborgs universitet; []
    Nyckelord :X-ray Computed Tomography; Magnetic Resonance Imaging; Body Composition; Obesity; Metabolic Syndrome X; Glucose Metabolism; Growth Hormone; Fatty Liver; Intra-Abdominal Fat;

    Sammanfattning : Background: Computed tomography (CT) and magnetic resonance imaging (MRI) provide important research opportunities due to their unique capability of characterizing and quantifying tissues and organs. Ionizing radiation is a limitation using CT, and recent developments aiming to improve MRI for determination of body composition have not been validated. LÄS MER

  5. 4. On cardiac flow quantification with ultrasound colour doppler

    Författare :Joakim Brandberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis deals with the estimation of blood flow in the heart and larger vessels where control-volume methods are applied using ultrasound Doppler technique. In particular two control-volume techniques were investigated: The proximal isovelocity surface area method, (PISA) and the Surface Integration of Velocity Vectors method, (SIVV). LÄS MER

  7. 5. Solubility of hydrogen in slags and its impact on ladle refining

    Författare :Jenny Brandberg; Du Sichen; Mia Almcrantz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : The aim of the present work was to clarify the mechanisms of hydrogen removal during vacuum degassing. The main reason for this was because the primary source of hydrogen pick-up in steel-making is the moisture in the furnace atmosphere and the raw material charged into the ladle furnace. LÄS MER
