1. 1. Wafer-level heterogeneous integration of MEMS actuators

   Författare :Stefan Braun; Göran Stemme; Martin A. Schmidt; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microelectromechanical systems; MEMS; silicon; wafer-level; integration; heterogeneous integration; transfer integration; packaging; assembly; wafer bonding; adhesive bonding; eutectic bonding; release etching; electrochemical etching; microvalves; microactuator; Shape Memory Alloy; SMA; NITINOL; TiNi; NiTi; cold-state reset; bias spring; stress layers; crossbar switch; routing; switch; switch array; electrostatic actuator; S-shaped actuator; zipper actuator; addressing; transfer stamping; blue tape; Computer engineering; Datorteknik;

   Sammanfattning : This thesis presents methods for the wafer-level integration of shape memory alloy (SMA) and electrostatic actuators to functionalize MEMS devices. The integration methods are based on heterogeneous integration, which is the integration of different materials and technologies. LÄS MER

3. 2. Inflammatory responses in minor and major surgical procedures

   Författare :Annette Schmidt; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammatory response; surgery; cytokines; complement split products;

   Sammanfattning : Surgical procedures promote an inflammatory response, correlating to the extent of the procedure performed and influencing outcome after surgery. The aims of the thesis were to investigate factors modulating the inflammatory response perioperatively and to evaluate cell salvage for indications so far not accepted in clinical practice. LÄS MER

4. 3. Bone mineral density in pediatric inflammatory bowel disease

   Författare :Susanne Schmidt; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone mineral density; inflammatory bowel disease; children; Crohn s disease; ulcerative colitis; vitamin D; parathyroid hormone; familial resemblance; body composition; growth;

   Sammanfattning : Low bone mineral density (BMD) has been highlighted as a potential problem in children with inflammatory bowel disease (IBD), which is one of the most common chronic childhood diseases in the westernized world. The mechanisms behind reduced BMD in pediatric IBD are still not completely understood, but several factors that influence bone mineralization have been discussed. LÄS MER

5. 4. Fragmentation of Amino Acids and Microsolvated Peptides and Nucleotides using Electrospray Ionization Tandem Mass Spectrometry

   Författare :Henrik Johansson; Henning Schmidt; Henrik Cederquist; Jens Jensen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylfysik; fysik; Physics;

   Sammanfattning : This thesis presents three different series of high energy (keV) collision experiments as well as a brief scientific introduction to the field. In the first series, protonated glycine and leucine were collided with carbon dioxide and a beam attenuation method was applied to determine their total fragmentation cross sections. LÄS MER

7. 5. Ions in cold electrostatic storage devices

   Författare :Peter Reinhed; Henning Schmidt; Henrik Cederquist; Jason Greenwood; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylfysik; fysik; Physics;

   Sammanfattning : We have constructed a compact purely electrostatic ion-beam trap, ConeTrap, which we have mounted inside a double-walled vacuum chamber. In the inner vacuum chamber, we can obtain ultra-high vacuum (UHV) conditions and reach thermal equilibrium at well controlled temperatures down to 10 K. LÄS MER
