  2. 1. Transvascular fluid exchange with application to the brain. An experimental study in cat skeletal muscle and brain

    Author : Lis Kongstad; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; intensivvård; capillary filtration coefficient; Capillary permeability; reflection coefficient; brain edema; dural puncture; Anaesthesiology; Anestesiologi; intensive care; neuropsykologi; neurofysiologi;

    Abstract : This study evaluated transcapillary fluid exchange in the cat brain and in a cat skeletal muscle enclosed in a plethysmograph. A method for determination of capillary permeability (capillary filtration coefficient and reflection coefficient) and effects of transcapillary hydrostatic pressure changes were studied We found that capillary fluid permeability in a tissue can be determined by the capillary filtration coefficient, even when arterial pressure and vascular tone are changed.

  4. 2. Utility of bispectral index (BIS) monitoring during general anesthesia

    Author : Maj-Lis Lindholm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The possibility to objectively measure effects from anesthetics on the level of consciousness has since long been desired. General anesthetics cause changes in brain electrical activity, seen as changes in the electroencephalogram (EEG). READ MORE

  5. 3. Concepts for hot sheet metal forming of titanium alloys

    Author : Eva-Lis Odenberger; Roger Reed; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot sheet metal forming; Titanium; FE simulation; Validation; Springback; HCP; Varmforming; Titan; FE simulering; Validering; Återfjädring; HCP; Hållfasthetslära; Solid Mechanics;

    Abstract : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. READ MORE

  6. 4. Material characterisation for analyses of titanium sheet metal forming

    Author : Eva-Lis Odenberger; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : New demands and opportunities for simulation driven product development, that today's finite element (FE) technology allow for, exists in modern industry. Full applicability, in which decisions based on numerical evaluations and predictions, require accurate material parameters and of course accurate modelling of remaining features. READ MORE
