  1. 16. Enantiomeric separation by capillary electrophoresis : With special emphasis on the partial filling technique

    Författare :Ahmad Amini; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : Capillary electrophoresis as a powerful separation technique was employed for resolution of racemic drugs. Taurodeoxycholate (TDC), different cyclodextrins and α1- acid glycoprotein (AGP) were dissolved in the background electrolyte at low pH (3.0 to 4.0 ) as chiral selectors. LÄS MER

  3. 17. Work Practice, Safety and Heedfulness : Studies of Organizational Reliability in Hospitals and Nuclear Power Plants

    Författare :Vincent Gauthereau; Karlene H. Roberts; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The study of safety in complex systems has focused on different issues over the past decades. This focus was often linked to the conclusions of previous accidents' / incidents' analyses. When accidents were attributed to technical causes, safety research focused on technical developments.

  4. 18. Lithium-ion batteries for off-grid PV-systems

    Författare :Fabian Benavente; Göran Lindbergh; Anders Olof Lundblad; Saul Cabrera; Daniel Abraham; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; aging; partial cycles; DVA; EIS; NCA; stationary energy systems; PV systems; rural electrification.; Chemical Engineering; Kemiteknik;

    Sammanfattning : This thesis provides a comprehensive and detailed analysis on the effect ofthe battery operation strategy on the lifetime of commercial lithium-ionbatteries and on the economics of off-grid photovoltaic (PV)-batterysystems.Lithium-ion batteries play a key role in the transition to a fossil-freesociety.

  5. 19. Uncertainty and Risk Analysis in Fire Safety Engineering

    Författare :Håkan Frantzich; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event tree; fire engineering design; reliability index; FOSM; Monte Carlo simulation; Risk analysis; uncertainty analysis; response surface.; Technological sciences; Teknik;

    Sammanfattning : Two Quantitative Risk Analysis (QRA) methods are presented which can be used to quantify the risk to occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. LÄS MER

  7. 20. Diagnostics of stator insulatin by dielectric response and variable frequency partial discharge measurements : a study of varied low frequencies in stator insulation, with particular attention to end-winding stress-grading

    Författare :Nathaniel Taylor; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : Stator insulation is a critical to the reliability of electrical generators and motors. It is common industrial practice to use electrical measurement of partial discharges (PD) and some form of current-voltage measurement as part of the condition assessment of stator insulation at maintenance times.
