  2. 16. Global stability analysis of complex fluids

    Author : Iman Lashgari; Luca Brandt; Francois Gallaire; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-Newtonian flow; Carreau model; Oldroyd-B model; FENE-P model; modal analysis; nonmodal analysis; sensitivity analysis;

    Abstract : The main focus of this work is on the non-Newtonian effects on the inertial instabilities in shear flows. Both inelastic (Carreau) and elastic models (Oldroyd-B and FENE-P) have been employed to examine the main features of the non-Newtonian fluids; shear-thinning, shear-thickening and elasticity.

  4. 17. Tissue Doppler in Spectral and Color ModeMethodological ConsiderationsNon-invasive Estimation of Left Ventricular Filling Pressures using the E/Em index

    Author : Aristomenis Manouras; Lars Åke Brodin; Michael Henein; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue Doppler; Cardiology; Kardiologi;

    Abstract : Aims: Tissue Doppler (TD) in spectral mode (spectral TD) and color TD are the two modalities available today in tissue velocity echocardiography (TVE). Measurements of left ventricular (LV) myocardial velocities and displacement may yield different results depending on the employed sonographic modality and the subjective adjustments during data analysis.

  5. 18. Modelling precipitation and surface complexation reactions in systems with Goethite, Cu(II) and Oxyanions Containing As(V) or P(V)

    Author : Hanna Nelson; Lars Lövgren; Staffan Sjöberg; Per Persson; M. Clara F. Magalhaes; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aqueous solubility of oxyanion (e.g. phosphates and arsenates), and thereby their mobility, bioavailability (phosphates) and toxicity (arsenates), in soils and sediments is dependent upon their chemical speciation. In complex, multicomponent systems, equilibrium modelling can be a useful tool to predict chemical speciation. READ MORE

  6. 19. Rectal washout in rectal cancer surgery

    Author : Rebecca Svensson Neufert; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rectal washout; Rectal cancer surgery; Local recurrence; Anterior resection; abdominoperineal resection; Transanal total mesorectal excision;

    Abstract : BackgroundRectal washout (RW) is performed to eliminate intraluminal cancer cells and thereby reducing the risk of local recurrence (LR). The overall aim of this thesis was to investigate the importance of RW in rectal cancer surgery.MethodPaper I: Survey of the current practice of RW among Swedish colorectal units. READ MORE

  7. 20. The clinical value of total isovolumic time

    Author : Gani Bajraktari; Michael Henein; Krister Lindmark; Lars-Åke Brodin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; cardiac resynchronization therapy; predictors; echocardiography; total isovolumic time; six-minute walk test; left ventricular dyssynchrony;

    Abstract : The objective of this thesis is to evaluate the use of Doppler echocardiography markers ofglobal dyssynchrony [total isovolumic time (t-IVT)] in the following 6 studies: 1) Its prognostic role in predicting cardiac events in patients undergoing CABG surgery,compared with conventional global systolic and diastolic measurements. 2) Its additional value in predicting six minute walk test (6-MWT) in patients with leftventricular (LV) ejection fraction (EF) .
