  1. 6. Kretslopp från avlopp : enterokocker som indikatororganismer och bärare av Vankomycinresistens

    University essay from SLU/Department of Molecular Sciences

    Author : Maja Berglind; [2023]
    Keywords : Enterococcus; enterokocker; urea; E. faecalis; E. faecium; hygienisering; ureahygienisering; ammoniak; svartvatten; klosettvatten; klosettavloppsvatten; avloppsvatten; antibiotikaresistens; Vankomycin; Vancomycin; CHROMagar; Slanetz-Bartley agar; indikatororganism;

    Abstract : Tillförsel av växtnäring på åkermark är nödvändig för matproduktionen. En återförsel av mänskliga fekalier och urin via källsorterat toalettavfall (klosettavloppsvatten) ökar cirkulationen av näring, bidrar till förbättrad jordhälsa och minskar risken för övergödning i vattendrag.

  3. 8. Financial viability of producing hydrogen in windfarms in the Nordic region

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Juan Munoz; [2023]
    Keywords : Hydrogen; Wind; Energy; Ammonia; Nordic;

    Abstract : With the perspective of a growing hydrogen market that responds to the energy sector requirements for a carbon-free fuel and/or storage method, analyzing the financial viability of producing green hydrogen in the Nordic region is of great importance to understand the possibilities of local supply and the role that the strongly present wind industry can have in it.  Additionally, the possibility of the construction of a dedicated hydrogen pipeline connecting Sweden, Finland, Denmark, and possibly other countries in the Nordic area, changes the previously analyzed scenarios of only local demand, close to production; incorporating this infrastructure into the simulations will shed light upon the possibilities for a Nordic hydrogen market.
