    Sammanfattning : A set of vital societal functions such as health and safety are necessary for today's society to function and to secure the life of its individuals. Infrastructure is required to provide and maintain these functions. LÄS MER

  3. 17. Aerodynamic assessment of velopharyngeal function in speech

    Författare :Hans Dotevall; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Speech production measurements; speech aerodynamics; velopharyngeal function; nasal airflow; perceptual speech evaluation; hypernasality; cleft palate speech; sleep disordered breathing; snoring; sleep apnea;

    Sammanfattning : Velopharyngeal function in speech was assessed by aerodynamic techniques, which were developed and tested. Temporal and dynamic characteristics of the nasal airflow pattern during the velopharyngeal closing phase in speech were studied in different patient groups. Its validity in relation to listener's perceptual evaluation of speech was analyzed. LÄS MER

  4. 18. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

    Sammanfattning : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.
