  1. 1. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Anton Wagner; [2022]
    Nyckelord :Bottom currents; Sortable silt; Radiocarbon dating; Baltic Sea stages; Estuarine circulation; Marine sediment cores; Marine geophysical mapping;

    Sammanfattning : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. LÄS MER

  3. 2. Experimental Spironucleus infections in Atlantic salmon (Salmo salar) : Hidden secrets of the life cycle of Spironucleus salmonicida revealed

    Magister-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Anders Alfjorden; [2018]
    Nyckelord :Parasite; Salmon; Infection; Diplomonada; Spironucleus;

    Sammanfattning : We have performed experimental infections of Atlantic salmon (Salmo salar) from the Baltic Sea region with the protozoan parasite Spironucleus salmonicida. By this infection trial we have been able to show that the life cycle may use an alternative route of transmission. LÄS MER

  4. 3. Seasonal changes in clupeids maturation constrains the food quality of chicks of the common guillemot (Uria aalge) : A case study of a potential mismatch, from the perspective of the common guillemot chicks on Stora Karlsö, the Baltic Sea

    Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

    Författare :Emelie Delphin; [2018]
    Nyckelord :Common guillemot Uria aalge ; Sprat Sprattus sprattus ; Herring Clupea herengus ; Match-mismatch hypothesis; the Baltic Sea;

    Sammanfattning : Background: Common guillemots are integral elements of the Baltic Sea marine ecosystem. They possess life-history characteristics such as relatively long lifespan, quite low fecundity resulting in only one egg per breeding season – characteristics that make them particularly vulnerable to even small changes in the environment.

  5. 4. Ultrafiltration of Bleach Plant Efflunet from a Sulphite Pulp Mill-Influence of operating parameters

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erna Trokic; [2017]
    Nyckelord :Ultrafiltration; bleach plant effluent; sulphite pulp mill; Technology and Engineering;

    Sammanfattning : Stora Enso Nymölla Mill is an integrated pulp and paper mill located in south Sweden near the Baltic Sea. The mill uses ultrafiltration (UF) to remove compounds with a high chemical oxygen demand (COD) from the bleach plant effluent. UF is a separation technology using membranes. LÄS MER

  7. 5. Utsläpp från svenska reningsverk till Östersjön : Granskning av Henriksdals reningsverk, Ryaverket, Sjölunda reningsverk, Kungssängsverket och Duvbackens reningsverk

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Dolovan Ahmed; Mohammed Erik Jamal Fadul; [2017]
    Nyckelord :Purification plant; phosphorus; nitrogen; mechanical purification; biological purification; chemical purification; person equivalent pe .; Reningsverk; fosfor; kväve; mekanisk rening; biologisk rening; kemisk rening; personekvivalent pe .;

    Sammanfattning : From domestic and industrial waste water will have to be cleaned before it can be released into lakes and streams again. This purification takes place through various stages of treatment plants. LÄS MER
