  1. 21. Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export

    Författare :Isabelle Giddy; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; sea ice; submesoscale; diapycnal mixing; heat fluxes; primary production; carbon export; gliders.;

    Sammanfattning : The sea ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, along-isopycnal upwelling of warm, carbon-rich circumpolar deep water coincides with the annual growth and melt of Antarctic sea ice that represents one of the worlds largest surface water transformations.

  2. 22. Microplastic Mitigation in Urban Stormwater : Assessing Horizontal-Flow Filters of Bark, Biochar and Sand as Remediation Strategies

    Författare :Gabriella Rullander; Sahar S. Dalahmeh; Roger Herbert; Jes Vollertsen; Claudia Lorenz; Ann-Margret Strömvall; Giuliano Di Baldassarre; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Decentralized water treatment; Filtration; Filter systems; Pollution control; Porous media; Stormwater management; Sustainable solutions; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Sammanfattning : Urban stormwater has been suggested as a significant vector through which microplastics (MPs) reach aquatic environments. Currently, only a small fraction of stormwater in Sweden undergoes any form of treatment. LÄS MER

  3. 23. On the Chemical Composition of Metal-Poor Stars : Impact of Stellar Granulation and Departures from Local Thermodynamic Equilibrium on the Formation of Spectral Lines

    Författare :Remo Collet; Bengt Gustafsson; Martin Asplund; Roger Cayrel; Uppsala universitet; []
    Nyckelord :Astronomy; late-type stars; stellar abundances; stellar atmospheres; spectral line formation; convection; hydrodynamics; Galactic chemical evolution; Astronomi;

    Sammanfattning : The information about the chemical compositions of stars is encoded in their spectra. Accurate determinations of these compositions are crucial for our understanding of stellar nucleosynthesis and Galactic chemical evolution. LÄS MER

  4. 24. A study of the traits associated with the biocontrol activity of Phlebiopsis gigantea

    Författare :Anthony Christian Mgbeahuruike; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Phlebiopsis gigantea has routinely been used for the biocontrol of the conifer pathogen, Heterobasidion annosum s.l. but the mechanism for the biocontrol action has not been properly understood. In the present work, 64 isolates of P. LÄS MER

  5. 25. Fuel retention and fuel removal from first wall components in tokamaks

    Författare :Darya Ivanova; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik;

    Sammanfattning : Fuel inventory and generation of carbon and metal dust in a tokamak are perceived to be serious safety and economy issues for a steady-state operation of a fusion reactor, e.g. ITER. These topics have been explored in the on-going Ph. LÄS MER
