  1. 1. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

    Detta är en avhandling från Luleå University of Technology

    Författare :Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering;

    Sammanfattning : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

  2. 2. Changes in the Freshwater System Distinguishing Climate and Landscape Drivers

    Detta är en avhandling från Stockholm : Department of Physical Geography, Stockholm University

    Författare :Fernando Jaramillo; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; naturgeografi; Physical Geography;

    Sammanfattning : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

  3. 3. Partitioning of Drugs and Lignin Precursor Models into Artificial Membranes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Elisabet Boija; Uppsala universitet.; [2006]
    Nyckelord :Biochemistry; Bilayer disk; Capillary electrophoresis; Detergent; Drug; Electrostatic interaction; Hydrophobic interaction; Immobilized liposome chromatography; Lignin; Lignin precursor model; Liposome; Membrane model; Octanol water partitioning; Partitioning; Phospholipid; Phospholipid bilayer; Sterol; Biokemi;

    Sammanfattning : The main aim of this thesis was to characterize membrane-solute interactions using artificial membranes in immobilized liposome chromatography or capillary electrophoresis. The partitioning of a solute into a cell membrane is an essential step in diffusion across the membrane. LÄS MER

  4. 4. Partitioning of biomolecules in thermoseparating polymer-water two-phase systems

    Detta är en avhandling från Hans-Olof Johansson, University of Lund, Dept. of Biochemistry, P.O.B. 124, S-221 00 Lund, Sweden

    Författare :Hans-Olof Johansson; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aqueous two-phase system; temperature-induced phase separation; amino acid and peptide separation; polymer; partitioning; Biology; Biologi;

    Sammanfattning : The partitioning behaviour of different types of molecules in thermoseparating two-phase systems has been studied. A thermoseparating two phase system was formed by heating a water solution, which contained a thermoseparating polymer, above the cloud point temperature. LÄS MER

  5. 5. Partitioning and persistence of volatile methylsiloxanes in aquatic environments

    Detta är en avhandling från Hans-Olof Johansson, University of Lund, Dept. of Biochemistry, P.O.B. 124, S-221 00 Lund, Sweden

    Författare :Dimitrios Panagopoulos; Matthew MacLeod; Annika Jahnke; Amelie Kierkegaard; Whelan Mick; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; siloxanes; organic carbon; sediment; partitioning; persistence; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The presence of volatile methylsiloxanes (VMS) in the environment has raised concerns among environmental chemists and regulators about their persistence and the risks they may pose to the environment. This thesis explores the partitioning and persistence of VMS in aquatic environments. LÄS MER
