  1. 11. Wave Power for Desalination

    Författare :Jennifer Leijon; Cecilia Boström; Irina Temiz; Jens Engström; Deborah Greaves; Uppsala universitet; []
    Nyckelord :Wave power; desalination; freshwater; engineering education; linear generator; wave energy converter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : This doctoral thesis presents work related to wave powered desalination. Wave power for desalination could be an interesting alternative for islands or coastal regions facing freshwater shortage, and several systems have been proposed in literature. However, desalination is a process which demands a lot of energy. LÄS MER

  3. 12. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates

    Författare :Warren Kunce; Frank Johansson; Jan Örberg; Sarah Josefsson; Jes Rasmussen; Uppsala universitet; []
    Nyckelord :ecotoxicology; sub-lethal; behavior; biomarkers; thermal tolerance; pesticides; pyrethroids; neonicotinoids; pharmaceuticals; antihistamines; microplastics; mixtures; freshwater; invertebrates; chironomids; damselflies; snails; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

    Sammanfattning : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. LÄS MER

  4. 13. The effects of exposure to microplastics and pollutants on the arthropod microbiome

    Författare :Javier Edo Varg; Richard Svanbäck; Jarone Pinhassi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ecotoxicology; host microbiota; freshwater; anthropogenic pollution; microplastics; pesticides; pyrethroids; detergents; toxic metals; daphnids; chironomids; water boatmen; damselflies; dragonflies;

    Sammanfattning : Anthropogenic pollution is widespread across various ecosystems. This disturbance can alter the interaction between a host and its associated microbiome, with repercussions for hosts traits such as health, behavior, and host evolution. LÄS MER

  5. 14. Transcriptional biomarkers of toxicity – powerful tools or random noise? : An applied perspective from studies on bivalves

    Författare :Gustaf Magnus Oskar Ekelund Ugge; Olof Berglund; Annie Jonsson; Helena Westerdahl; Mikael Ejdebäck; Bruno Nunes; Högskolan i Skövde; []

    Sammanfattning : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. LÄS MER

  7. 15. Polychlorinated biphenyls (PCB) in a river ecosystem

    Författare :Gudrun Bremle; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; dredging; landfill; cleanup; remedial action; air; fish; sediment; Persistent organic pollutants; freshwater; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : Atmospheric deposition is one source of persistent pollutants such as polychlorinated biphenyls (PCB) in aquatic environments. Other point sources can also contribute to the PCB loadings in the water. LÄS MER
