  1. 16. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

    Författare :Edoardo De Robertis; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomografi; medicinsk instrumentering; radiologi; Klinisk fysiologi; tomography; medical instrumentation; Respiratory system; Andningsorganen;

    Sammanfattning : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. LÄS MER

  3. 17. Experimental and numerical investigations of hydrodynamic focusing of colloidal dispersions

    Författare :V. Krishne Gowda; Fredrik Lundell; Daniel Söderberg; Lynn Walker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; flow focusing; colloidal fiber dispersion; effective interfacial tension; microflow morphology; nanoparticle orientation; Mikrofluidik; flödesfokusering; kolloidala dispersioner; effektiv ytspänning; mikroflödesmorfologi; orientering av nanopartiklar; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Dispersed non-spherical particles are the fundamental constituent of many complex fluids. Such fluids are studied both for their industrial and scientific importance, and for their peculiar functional properties (mechanical, optical, thermal, fluidic). LÄS MER

  4. 18. Major Intrinsic Proteins - Structure, function, interactions

    Författare :ANDREAS KIRSCHT; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporin; membrane proteins; crystallography; stopped-flow; molecular dynamics; structure modeling;

    Sammanfattning : Major intrinsic proteins, also referred to as aquaporins (AQPs) are localized in membranes of all domains of life to increase the permeability to water or other small, polar molecules. Several monophyletic groups can be discerned in this large and divergent protein superfamily. LÄS MER

  5. 19. Probing Proton Translocation in Influenza A/M2 Proteoliposomes - A systematic Approach to Membrane-Protein Reconstitutions

    Författare :Thom Leiding; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : An improved method for reconstituting membrane proteins into artificial liposomes for quantitative functional analysis is presented. A number of key parameters for reconstitution by detergent removal are assessed in this thesis: The lipid-to-protein ratio, the detergent-to-lipid ratio and the lipid and cholesterol composition.

  7. 20. Statistical Physics of DNA: Melting and Confinement Effects

    Författare :Michaela Reiter-Schad; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; DNA melting; DNA confinement; random walk; Fysicumarkivet A:2015:Reiter-Scad;

    Sammanfattning : Investigation of single macromolecules makes it possible to gain insight into and characterize important biological processes. DNA as the molecule of life is of special interest here. LÄS MER
