  1. 1. TROFISK ÖVERFÖRING OCH TOXISKA EFFEKTER AV (NANO-)PARTIKLAR FRÅN ELEKTRONISKT AVFALL

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Elvira Hagman; [2023-06-22]
    Nyckelord :;

    Sammanfattning : Today, nanoparticles (NPs) are being included in an increasing number of products, and with that comes the dispersion of NPs in the environment. However, the ecological impact of NPs remains largely unexplored, particularly in regards to real emissions with complex compositions of NPs and other pollutants. LÄS MER

  3. 2. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jonna Hellesten; [2023-01-26]
    Nyckelord :;

    Sammanfattning : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

  4. 3. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Duncan Jones; [2023]
    Nyckelord :Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Sammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER

  5. 4. Under Rosen : IB: Nationell säkerhetstjänst, Politisk polis eller Stat i staten?

    Master-uppsats, Försvarshögskolan

    Författare :Markus Hjelm; [2023]
    Nyckelord :Underrättelse; IB; Kalla kriget; ansvarsutkrävande; Peter Gill; civil kontroll; civil-militära relationer;

    Sammanfattning : Civilian control over military forces is a prerequisite within democracies in the study of civil-military relations. This requirement extends to military intelligence, as they are a part of the military. However, this relationship needs to balance secrecy with transparency concerns, a relationship which can prove difficult. LÄS MER

  7. 5. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Monica Olsson; [2022-10-05]
    Nyckelord :Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

    Sammanfattning : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. LÄS MER
