  1. 11. Optimization of the Sensor-Chip Surface in a Capacitive Biosensor for use in Aflatoxin Assays

    Författare :Alvaro Gutierrez Rojas; Bioteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aflatoxin; biosensor; antibody; bioimprinting; gold nanoparticles; capacitance;

    Sammanfattning : The capacitive biosensor technology can be utilized for the analytical detection of a variety of different compounds. By employing the electrical double-layer principle, it is possible to detect very low concentrations of the target analyte due the methods inherent high sensitivity. LÄS MER

  3. 12. Diagnostics of Oil-Impregnated Paper Insulation Systems by Utilizing Lightning and Switching Transients

    Författare :Roya Nikjoo; Hans Edin; Christer Törnkvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitance; Dielectric Response; Loss tangent; Moisture content; Oil - impregnated paper; Temperature; Transformer Bushing; Transients;

    Sammanfattning : Development of the power gridtowards a more reliable and smarter system requires frequent on-line monitoring of the power components. Power transformers and their bushings are particularly important components in a power transmission system and their insulation degradation may lead to catastrophic failures. LÄS MER

  4. 13. Cardiovascular responses to hypovolemic circulatory stress in women : With special reference to venous compliance and capacitance

    Författare :Marcus Lindenberger; Toste Länne; Peter Friberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiology; Kardiologi;

    Sammanfattning : Acute haemorrhage is a leading cause of death in trauma. Young women (YW) seem more susceptible to hypovolemic circulatory stress than young men (YM), but the underlying mechanisms are not clear. LÄS MER

  5. 14. Charging effects in small capacitance Josephson junction circuits

    Författare :Peter Ågren; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis describes fabrication, measurements and analysisof two different Josephson junction circuits; the Cooper pairtransistor (CPT) and the one dimensional Josephson junctionarray (JJA). All experiments are conducted in a dilutionrefrigerator with a base temperature of 15{30 mK. LÄS MER
