  1. 16. Exogena östrogeners påverkan på fisk

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Angelica Johansson; [2019]
    Nyckelord :östrogen; fisk; vitellogenin; beteende; intersex;

    Sammanfattning : Fiskars proteiner är snarlika människans vilket gör att de i många fall kan påverkas av samma ämnen som oss. Hormonpreparat, naturliga östrogener och östrogena nedbrytningsprodukter passerar genom reningsverken och hamnar slutligen i vattenmiljön där fiskar exponeras för ämnena. LÄS MER

  3. 17. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Jaka Perovšek; [2018]
    Nyckelord :spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

    Sammanfattning : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. LÄS MER

  4. 18. Inhibition of Nitrification in Industrial Wastewater - Identification of Sources

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Vidar Aspelin; Jennifer Ekholm; [2017]
    Nyckelord :nitrite; nitrate; industrial wastewater; inhibition of nitrification; additivity; nitrifikationshämning; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Sammanfattning : The discharge of industrial wastewaters (WWs) to wastewater treatment plants (WWTPs) can be problematic due to their sometimes elevated concentrations of toxic compounds compared to municipal wastewater. Also, industrial WWs often contain compounds that are unique to the specific production, and the receiving WWTP is not always designed to remove these compounds. LÄS MER

  5. 19. The effect of barley on glucose regulation, appetite and colonic fermentation in middle aged subjects

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Jananee Muralidharan; [2017]
    Nyckelord :Food science; barley; gut microbiota; nutrition; Agriculture and Food Sciences;

    Sammanfattning : Use of wholegrain foods has shown importance in terms of prevention of obesity and related comorbidities. Positive metabolic effects of wholegrain barley have been investigated with this regard. LÄS MER

  7. 20. Effectiveness of a fish-guiding device for downstream migrating smolts of Atlantic salmon (Salmo salar L.) in the River Piteälven,northern Sweden

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Linda Vikström; [2016]
    Nyckelord :salmon smolt; spill gate passage; turbine-mortality; fish way; guidance structure;

    Sammanfattning : Hydropower poses a major threat to both upstream and downstream migrating Atlantic salmon (Salmo salar L.). To ensure a relatively safe route for migrating fish, fish ways and different guidance structures are constructed to help fish to bypass the turbine intakes to power stations. LÄS MER
