  1. 26. Cryptic coloration, microhabitat choice and polymorphism in Idotea baltica (Isopoda)

    Författare :Sami Merilaita; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Sammanfattning : In this thesis I have studied cryptic coloration, microhabitat use and colour polymorphism in the marine isopod Idotea baltica. In the Baltic Sea it lives and feeds mainly on the seaweed Fucus vesiculosus, which in sheltered sites usually is whitespotted on its lower parts due to epizoites. The white-spotted morph of I.

  3. 27. Towards a Sustainable Biomass and Waste Refinery Based on Pyrolysis Combined with a Pretreatment Process

    Författare :Yuming Wen; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; anaerobic digestion; hydrothermal carbonization; refinery; biomass; waste; kinetics; LCA; Energiteknik; Energy Technology; Chemical Engineering; Kemiteknik;

    Sammanfattning : Some of the naturally accumulated biomass and the massive production of waste by human activities have caused serious environmental problems. The degradation of biomass and waste is one of the main greenhouse gasses (GHG) emission sources. LÄS MER

  4. 28. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials

    Författare :Linn Berglund; Kristiina Oksman; Monika Österberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibers; Industrial residues; Ultrafine grinding; Energy-efficiency; Network formation; Hydrogel; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Bio-based resource utilization in different forms has been driven by societal, industrial and academic research interests towards the development of “green”, sustainable materials from renewable sources. Within this context, exploiting biomass from different industrial residues is further advantageous from an environmental and economic point of view, leading to minimization of residues by means of waste treatment and to the development of high-addedvalue- products.

  5. 29. Biochemical and spectral characterization of micro- and macroalgae

    Författare :Calle Niemi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Algae contain many compounds which are of interest to the pharmaceutical, agricultural and food industries, among others. Despite the potential for many applications, a quick, accurate and inexpensive method for characterising algae is lacking. LÄS MER

  7. 30. Novel Marine Ingredients for Aquaculture - Fish Nutrition, Physiology and Intestinal Health

    Författare :Niklas Warwas; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Marine ingredients; Intestinal health; Sustainable feed; Circular economy; Aquaculture;

    Sammanfattning : Aquaculture is among the fastest growing food production sectors globally and supplies more fish to the growing human population than capture fisheries. One of the major challenges in salmonid aquaculture is to find renewable and sustainable feed ingredients which also satisfy the nutritional requirements of the fish. LÄS MER
