1. 6. On microchannel acoustophoresis - Experimental considerations and life science applications

   Författare :Per Augustsson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microtechnology; microfluidics; lab on a chip; separation; acoustophoresis; ultrasound; acoustic resonance; acoustic radiation force; phage display; circulating tumour cells; acoustofluidics;

   Sammanfattning : This thesis presents experimental studies of microchannel acoustophoresis, a technique for manipulation of microscopic objects in suspension by means of acoustic radiation forces induced by ultrasonic standing wave fields. By arranging an acoustic resonance across the width of a microchannel, the path of individual cells or microparticles can be deflected orthogonally to the fluid flow. LÄS MER

4. 8. Inside the black box of workplace interventions : investigating the influence of context and process on outcomes

   Författare :Hanna Augustsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Introduction: Staff working in healthcare and residential care for older people are continuously required to learn and develop competencies to keep up with medical, technological and social developments. At the same time, they experience a work situation generally characterized by high demands. LÄS MER

5. 9. On enchytraeids and naidids: Life history traits and responses to environmental stress

   Författare :Anna-Karin Augustsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; oligochaeta; terrestrial naididae; toxicity testing; asexual reproduction; sexual reproduction; drought; environmental stress; metal pollution; Ekologi; Animal ecology; Djurekologi;

   Sammanfattning : My thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. LÄS MER

7. 10. Soft X-ray Emission Spectroscopy of Liquids and Lithium Battery Materials

   Författare :Andreas Augustsson; Joseph Nordgren; Jinghua Guo; Kevin Smith; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Soft X-ray emission; resonant inelastic X-ray scattering; lithium battery; electronic structure; liquid water; Atom- och molekylfysik; Atomic and molecular physics; Atom- och molekylfysik;

   Sammanfattning : Lithium ion insertion into electrode materials is commonly used in rechargeable battery technology. The insertion implies changes in both the crystal structure and the electronic structure of the electrode material. LÄS MER
