  2. 1. Pulsed Tissue Doppler and left ventricular filling in acute coronary syndromes

    Author : Cecilia Wallentin Guron; Göteborgs universitet; []
    Keywords : Tissue Doppler; pulsed; regional timing; time interval; the E e filling index; E E; ; diastolic function; left ventricular filling pressure; right ventricular pressure; left atrial size.;

    Abstract : Pulsed tissue Doppler is a new technique, which can investigate longitudinal left ventricular(LV) function, by measuring tissue velocities and timings. Patients with acute coronarysyndromes (ACS) frequently display a reduced longitudinal function. They also developglobal LV filling impairment. READ MORE

  4. 2. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography

    Author : Toomas Kangro; Uppsala universitet; []
    Keywords : Medical sciences; Arterial distensibility; diastole; Doppler echocardiography; exercise; healthy persons; hypertension; LV filling; menopause; medicin; vård; MEDICINE; MEDICIN; Clinical Physiology; Klinisk fysiologi;

    Abstract : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. READ MORE

  5. 3. Modeling of Initial Mold Filling in Uphill Teeming Process Considering a Trumpet

    Author : Zhe Tan; Pär Jönsson; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gating system; uphill teeming; ingot casting; swirl blade; flow pattern; realizable k-ε model; CFD; mathematical modeling.;

    Abstract : The flow pattern in the uphill teeming process has been found to be closely related to the quality of ingots and further to affect the yield of ingot production, which is crucial for the steel making process. The formation of non-metallic inclusion and entrapment of mold flux has been considered to be affected by the flow pattern in the gating system and molds by many previous researchers. READ MORE

  6. 4. Tensor Products of Highest Weight Representations and Skew-Symmetric Matrix Equations A+B+C=0

    Author : Ida Säfström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Highest weight respresentation; tensor product decomposition; orthogonal algebra; skew-symmetric matrix; Horn’s conjecture; moment map; coadjoint orbit; flag manifold; general linear algebra; infinite dimensional unitary representation; general linear algebra;

    Abstract : The question of characterizing the eigenvalues for the sum of two Hermitian matrices, was solved in 1999, after almost a century of efforts. The saturation conjecture for GL_C(n) was proven by Knutson and Tao, filling in the last gap in Horn’s conjecture. READ MORE

  7. 5. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming

    Author : Robert Eriksson; KTH; []
    Keywords : Laser flash method; thermal diffusivity; slags; inclusions; water model; ingot casting; up-hill teeming;

    Abstract : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. READ MORE
