  1. 11. Environmental impact of peat mining : Development of storm water treatment methods

    Författare :Bjørn Kløve; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; drainage artificial floodplaines; phosphorus; suspended solids; nitrogen; erosion; peat mining; peak runoff controll; sedimentation; water treatment; water resources; hydrology; hydraulics; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. LÄS MER

  3. 12. Numerical study of particle suspensions in Newtonian and non-Newtonian fluids

    Författare :Dhiya Alghalibi; Luca Brandt; Metin Muradoglu; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inertial suspensions; rheology; non-Newtonian fluids; visco-elastic; sedimentation; deformable particle; hyper-elastic.; tröghetsbehäftad suspension; reologi; icke-Newtonska fluider; vis- koelastik; sedimentering; deformerbara partiklar; hyperelastik; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Solid or deformable particles suspended in a viscous fluid are of scientific and technological interest in a broad range of applications. Pyroclastic flows from volcanoes, sedimentation flows in river bed, food industries, oil-well drilling, as well as blood flow in the human body and the motion of suspended micro-organisms in water (like plankton) are among the possible examples.

  4. 13. Computational studies of flow in Couette Rheometer and particle interaction in non-Newtonian fluids

    Författare :Naser Hamedi; Strömningsteknik; []
    Nyckelord :Non-Newtonian fluids; Correction factor; Fluid properties; Couette Rheometer; Particle interaction; Sedimentation; Computational Fluid dynamics; Plug flow; Herschel Bulkley; Power-law fluid; Immeresed boundary method;

    Sammanfattning : This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated. LÄS MER

  5. 14. Studies of Baltic Sea plankton - spatial and temporal patterns

    Författare :Helena Höglander; Ulf Larsson; Christoph Humborg; Anna-Stiina Heiskanen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton; Vertical distribution; Sedimentation; Baltic Sea; Cyanobacteria; Stable istopes; Cercopagis pengoi; Zooplankton; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : This thesis examines the spatial and temporal patterns of Baltic Sea phyto- and zooplankton. Studies of such patterns are important to gain a better understanding of the offshore nutrient dynamics of the Baltic Sea (Papers I and II) and how to manage eutrophication and invasive species in coastal areas (Papers III and IV).
