  4. 3. Structural and mechanistic aspects of alcohol dehydrogenase function

    Författare :Stefan Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Vertebrates possess a complex alcohol dehydrogenase (ADH) system composed of multiple molecular forms, which are currently classified into seven classes according to their structural properties. ADHs are dimeric zinc metalloenzymes that catalyze the reversible oxidation of alcohols to aldehydes/ketones using NAD+/NADH as electron acceptor and donor, respectively. LÄS MER

  5. 4. The Operational Problem of Fire Control

    Författare :Stefan Svensson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; control; tactics; operation; firefighting; procedure;

    Sammanfattning : The operational core of firefighting operations was examined. The effects of various firefighting procedures on the fire ground, their impact upon conditions on the fire ground in which decisions by commanding officers are made and the effects of allocating resources in time and space on the fire ground were explored.

  7. 5. Power Measurement Techniques for Nonsinusoidal Conditions. The Significance of Harmonics for the Measurement of Power and other AC quantities

    Författare :Stefan Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-sinusoidal; reactive; harmonics; power; sampling wattmeter;

    Sammanfattning : The increased application of power electronics and other non-linear loads makes it necessary to re-evaluate the measuring techniques used in the power system, and the measuring problems these loads cause. An instrument utilising digital sampling techniques has been built and evaluated at the Swedish National Testing and Research Institute (SP). LÄS MER
