  1. 16. Corrosion Fatigue of Stainless Steels

    Författare :Jan Linder; KTH; []
    Nyckelord :Stainless steel; corrosion fatigue; crack propagation; spot weld;

    Sammanfattning : The aim of this work was to investigate the effect ofchloride-containing environments on corrosion fatigueproperties for different stainless steels grades. The steelsinvestigated ranged from the standard 304 grade to thesuperaustenitic 654SMO and the superduplex SAF2507. LÄS MER

  3. 17. Polyelectrolyte adsorption on oppositely charged surfaces - Conformation and adsorption kinetics

    Författare :Lars-Erik Enarsson; Lars Wågberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte adsorption; adsorption kinetics; adsorption isotherms; conformation; bridging; stagnation point adsorption reflectometry; quartz crystal microgravimetry; polyelectrolyte titration; cationic polyacrylamide; cationic dextran; colloidal silica; silica surfaces; pulp; Chemistry; Kemi;

    Sammanfattning : Denna avhandling presenterar experimentella studier av polyelektrolytadsorption på motsatt laddade ytor, där substrat av både kiseloxid och blekt barrsulfatmassa har använts. Ett huvudsakligt syfte med denna forskning var att karaktärisera konformationen hos adsorberade skikt av katjonisk polyakrylamid (CPAM) i jämförelse med katjonisk dextran (Cdextran) och relatera denna information till inbindningskapaciteten av kolloidal kiselsyra.

  4. 18. Cerebral mechanisms in cardiovascular control : studies on haemorrhage and effects of sodium

    Författare :Robert Frithiof; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis describes experiments investigating the influence of the brain on cardiovascular adaptations to haemorrhage and excess sodium in conscious chronically prepared sheep. A continuous reduction in blood volume eventually activates a reflex that causes a fall in vascular resistance and heart rate and thereby also in arterial blood pressure. LÄS MER

  5. 19. Aspects of sepsis/SIRS - An experimental study on fluid therapy, vitamin C and plasma volume in increased permeability

    Författare :Björn Bark; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : In sepsis, after major surgery or severe trauma, the human body may suffer from various degrees of generalized inflammation, a syndrome called Systemic Inflammatory Response Syndrome (SIRS). One feature of SIRS is increased capillary permeability, caused by disruption of the capillary endothelium due to e.g. LÄS MER

  7. 20. Epitaxy of oxide and nitride thin films grown by magnetron sputtering

    Författare :Faezeh Alijan Farzad Lahiji; Per Eklund; Arnaud Le Febvrier; Biplab Paul; Tomas Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The need for electronic devices with new functionalities has caused research to move in a way to design and utilize materials with high-performance thermoelectricity, widely used in batteries, sensors, and electronic devices. Two-dimensional materials (2D) with unique structures and remarkable properties have been identified to fabricate oxide heteroepitaxy. LÄS MER
