    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Julia Stenius; [2019]
    Keywords : häst; mikrobiom; probiotika; foder;

    Abstract : Hästen är en herbivor vars naturliga diet till stor del består av gräs. För att kunna tillgodogöra sig strukturella kolhydrater är hästen helt beroende av mikrober, som i grovtarmen fermenterar cellulosa, hemicellulosa och pektin till lättupptagliga flyktiga fettsyror. READ MORE

  5. 5. Analysis of harmonic cross-modulation in HVDC line-commutated converters for practical design purposes

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Casper Karlsson; [2018]
    Keywords : Power transmission; design; filters;

    Abstract : The use of HVDC has many benefits over HVAC for some specific power transmission purposes. However, two major problems with HVDC links are that the converters produce harmonics and consume reactive power. Electrical filters are used to compensate for this and are a major cost driver of HVDC links. READ MORE
