  1. 21. Rock Mechanical Effects of Cement Grouting in Hard Rock

    Författare :Staffan Swedenborg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A pre-grouted rock mass is subjected to stress re-distribution as the tunnel excavation progresses. The strength and deformation characteristics of grouted rock joints are therefore of interest in any effort to predict the rock mechanical behavior as well as the failure of sealing in a grouted rock mass.

  3. 22. Invasive and Non-Invasive Quantification of Cardiac Kinematics

    Författare :Katarina Kindberg; Matts Karlsson; Bjørn Skallerud; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The ability to measure and quantify myocardial motion and deformation provides a useful tool to assist in the diagnosis, prognosis and management of heart disease. Myocardial motion can be measured by means of several different types of data acquisition. LÄS MER

  4. 23. Evaluation of isovolumic myocardial motions in human subjects using tissue velocity echocardiography

    Författare :Britta Lind; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Colour-coded tissue velocity imaging (TVE) with Echocardiography is an established method for evaluation of the global cardiac function and of the regional myocardial movements. The TVE-technique allows measurements of velocity and deformation variables from any discrete point in the myocardial wall during the cardiac cycle with high temporal and longitudinal spatial resolution.

  5. 24. Computer simulations of electronic energy transfer and a molecular dynamics study of a decapeptide

    Författare :Maria Lindberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electronic energy transfer; Monte Carlo simulations; two-particle model; GAF-theory; anisotropic systems; fluorescence depolarization ratios; Brownian Dynamics; rotating donors; Molecular Dynamics; peptide; renin inhibitor;

    Sammanfattning : Electronic energy transfer has been investigated in pure donor systems by means of computer simulations. Calculated properties were the probability that the initially excited donor is excited at a time t after the excitation, Gs(t), the mean square displacement of the excitation and different fluorescence observables.

  7. 25. Damage mechanics analysis of inelastic behaviour of fiber composites

    Författare :Peter Lundmark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Composite laminates under service loading undergo complex combinations of thermal and mechanical loading, leading to microdamage accumulation in the plies. The first mode of damage is usually intralaminar cracking with the crack plane transverse to the laminate middle-plane, spanning the whole width of the specimen. LÄS MER
