1. 6. Nucleator-driven assembly of curli organelles and their pathophysiological role in E. coli septic shock

   Författare :Zhao Bian; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Assembly; Curli; NOS2; Nucleator; Sepsis;

   Sammanfattning : The understanding of how polymeric surface structures are assembled in bacteria is one of general interests, which can provide insight into details of macromolecule interactions, and study how proteins fold into domains as assembly modules for building organelles. Protein-protein interactions in various subcellular compartments lead to the assembly of fimbriae at bacterial cell surfaces. LÄS MER

3. 7. Development of characterisation methods for the components of the polymer electrolyte fuel cell

   Författare :Jari Ihonen; KTH; []
   Nyckelord :polymer electrolyte membrane fuel cell; contacct resistance; clamping pressure; stainless steel; membrane degradation;

   Sammanfattning : In this work characterisation methods and fuel cell hardwarewere developed for studying the components of the polymerelectrolyte fuel cell (PEFC). Humidifiers and other componentswere tested in order to develop reproducible and reliableexperimental techniques. A set-up for testing larger cells andstacks was developed. LÄS MER

4. 8. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

   Författare :Ronald Whiddon; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

   Sammanfattning : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. LÄS MER

5. 9. Influenza A Virus : Spatial analysis of influenza genome trafficking and the evolution of the neuraminidase protein

   Författare :Dan Dou; Robert Daniels; Martin Schwemmle; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Influenza A virus; IAV; neuraminidase; NA; IAV genome trafficking; viral entry; viral replication; co-infection; antigenic drift; antigenic shift; NA assembly; transmembrane domain; evolution; Biochemistry; biokemi;

   Sammanfattning : Influenza A viruses (IAVs) are a common infectious agent that seasonally circulates within the human population that causes mild to severe acute respiratory infections. The severity of the infection is often related to how the virus has evolved with respect to the pre-existing immunity in the population. LÄS MER

7. 10. Integrated microsystems for continuous glucose monitoring, interstitial fluid sampling and digital microfluidics

   Författare :Federico Ribet; Niclas Roxhed; Göran Stemme; Boris Stoeber; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microelectromechanical systems MEMS ; biosensors; biomedical devices; continuous glucose monitoring CGM ; glucose sensors; microneedles; interstitial fluid sampling; minimally-invasive technologies; electrochemical sensors; heterogeneous integration; wire bonding; magnetic assembly; electrowetting-on-dielectric EWOD ; digital microfluidics; ionic liquids; gas sensors; optical switches; laser shutters.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Interdisciplinary research between medicine and microsystem engineering creates new possibilities to improve the quality of life of patients or to further enhance the performance of already existing devices. In particular, microsystems show great potential for the realization of biosensors and sampling devices to monitor bioanalytes with minimal patient discomfort. LÄS MER
