  6. 14. Transoesophageal and transthoracic recordings of mitral annulus motion

    Author : Bo Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Left ventricular function; echocardiography; M-mode; tissue Doppler; mitral annulus systolic and diastolic velocities;

    Abstract : Maximal systolic and diastolic velocities recorded from four sites of the mitral annulus motion (MAM) reflect left ventricular (LV) performance. This thesis focus on factors influencing M-mode derived velocities in healthy children and adults and reference values are proposed. READ MORE

  7. 15. An Experimental Study of Reynolds Stress Closures in Shear Free and Weakly Sheared Turbulence

    Author : Dag Aronson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulence modelling; dissipation measurements; Reynolds stress closures; isotropic turbulence; anisotropic dissipation rate tensor; hot-wire anemometry; wall proximity effects; pressure strain rate correlations;

    Abstract : The objective of this thesis work is to obtain data enabling evaluation of closure hypotheses used in the Reynolds stress transport (RST) equations. Special attention has been devoted to studies of flow fields with shear free and weakly sheared turbulence. READ MORE
