  1. 21. 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

  3. 22. Development of an Ultrasensitive Capacitive DNA-sensor: A promising tool towards microbial diagnostics

    Författare :Ally Mahadhy; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitive DNA-sensor; Enterobacteriaceae; mecA gene; Methicillin resistance; automated sequential injection analysis; sandwichhybridization; elevated temperature; polytyramine;

    Sammanfattning : Fast and sensitive detection of pathogenic microbial cells is a highly important task in medical diagnostics, environmental analysis and evaluation of food safety. Accordingly, the idea of microorganism identification by the recognition of specific DNA sequence using electrochemical technique is one of the leading researches in the development of diagnostic devices.
