1. 31. Influence of resuspension on sediment-water solute exchange and particle transport in marine environments

   Författare :Elin Almroth Rosell; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resuspension; benthic fluxes; oxygen; dissolved inorganic carbon; nutrients; dissolved iron and manganese; in situ chambers; benthic lander; organic matter transport; ecological modeling; Gothenburg Archipelago; Gulf of Finland; Baltic Sea; Loch Creran; Scotland;

   Sammanfattning : Marine sediments contain a large pool of nutrients, which if released would contribute to increased eutrophication, in spite of decreased nutrient loads from land and atmosphere. Resuspension is a process, which might influence the release of nutrients from the sediment to the overlying water. LÄS MER

3. 32. Land-Sea Interactions in the Coastal-Marine System of the Baltic Sea under Hydro-Climatic Variability

   Författare :Yuanying Chen; Vladimir Cvetkovic; Carmen Prieto; Marco Marani; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Baltic Sea; nutrient loads; hydro-climatic variability; hydrodynamics; solute transport; water quality.; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : This thesis investigates a few important component processes for understanding and quantifying eutrophication in the Baltic Sea, that include characterization of nutrient loadings from land, water flow in the sea under changing climate conditions and transport of solutes originating from different locations along the coast. Furthermore, this study aims to improve our understanding on how processes from land (the nutrient loading conditions) and the sea (transport dynamics and water quality) couple to determine the fate of nutrients in the sea and the water quality in a selected localized coastal area, the Himmerfjärden Bay.

4. 33. Generation of Leachate and the Flow Regime in Landfills

   Författare :David Bendz; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Sammanfattning : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. LÄS MER

5. 34. Marginal waters for irrigation and its erosion and solute transport

   Författare :Yasser Hamed Abd El Mageed; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Methods to collect rain water and prevent runoff in agricultural areas are described. The distribution of solutes in soil columns is is investigated in several environments... LÄS MER

7. 35. In vivo Pharmacokinetics of Two New Thrombin Inhibitor Prodrugs : Emphasis on Intestinal and Hepatobiliary Disposition and the Influence of Interacting Drugs

   Författare :Elin Matsson; Hans Lennernäs; Lars Knutson; Ulf Eriksson; Kim Brouwer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Direct thrombin inhibitors; prodrugs; ximelagatran; AZD0837; erythromycin; ketoconazole; drug-drug interactions; hepatobiliary transport; biliary clearance; ATP-binding cassette; ABC transporters; solute carriers; SLC transporters; CYP3A4; Biopharmacy; Biofarmaci; Biopharmaceutics; Biofarmaci;

   Sammanfattning : Biliary excretion is an important elimination route for many drugs and metabolites. For such compounds, it is important to know the extent of excretion and drug exposure in the bile, e.g., for the risk assessment of drug interactions, liver toxicity and the effects of genetic variants.
