1. 6. Multi-Photon Interactions with a Time Structure

   Författare :Alexander Baev; KTH; []
   Nyckelord :nonlinear optics; two-photon absorption; mirrorless lasing; charge-transfer chromophores; solutions; resonant photoemission; life-time vibrational interference; scattering duration time; electron Doppler effect; polymers;

   Sammanfattning : The present thesis concerns aspects of the interaction ofmatter in gas, liquid and solid phases, with electromagneticradiation, ranging from the optical to the X-ray region. Overthe last decade the availability of ultrashort strong laserpulses as well as of high power synchrotron sources of tunableX-ray radiation has stimulated a rapid development of newexperimental techniques which makes it possible to analysedifferent physical, chemical and biological processes inunprecedented detail.

   Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER

4. 8. Hydrogen in nano-sized metals : Diffusion and hysteresis effects

   Författare :Wen Huang; Björgvin Hjörvarsson; Max Wolff; Gavin Walker; Uppsala universitet; []
   Nyckelord :Hydrogen; diffusion; hysteresis; optical technique; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Metal hydrides can be used as hydrogen storage materials for fuel cells and batteries, and as sensors for detecting hydrogen gas. The use of metal hydrides for hydrogen storage can be hindered by poor kinetics and low capacity. Moreover, poor sensitivity, long recovery and response time, limit the applications of metal hydrides as hydrogen sensors. LÄS MER

5. 9. Preoperative deposit of autologous blood. Effects on inflammatory mediators

   Författare :Monica Hyllner; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allogeneic; autologous; complement; cytokines; blood storage; erythropoiesis; hysterectomy; plasma; prestorage leucocyte filtration; rHuEPO; whole blood.;

   Sammanfattning : Blood contains complex cascade systems and substances that can be activated during the processing of blood components and storage. Allogeneic blood, i.e. blood from someone else, is normally separated into components before storage and transfusion, while autologous blood (the patient s own blood) often is used as whole blood.

7. 10. Plasma as a Therapeutic Principle in Clinical Practice : With Special Reference to Sweden

   Författare :Rut A C Norda; Bo Nilsson; Bernd G Stegmayr; Kristina Nilsson-Ekdahl; Volker Kretschmer; Uppsala universitet; []
   Nyckelord :Immunology; adverse effects; contact activation; plasma exchange; plasma storage; severe sepsis; therapeutic apheresis; transfusion; Immunologi;

   Sammanfattning : The newly established Swedish Apheresis Registry makes it possible to do national inter-center comparisons. This study was undertaken to describe and analyze the use of therapeutic apheresis and the adverse effects in such therapy. LÄS MER
