  2. 11. Spatial and temporal dynamics of nutrients in two agricultural catchments in southeast Sweden

    Author : Andreas Milver; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HYPE-model; phosphorus; nitrogen; arable land; discharge; water quality modeling; snowmelt; nutrient transport; local information;

    Abstract : Many lakes and coast areas in Sweden and all over the globe suffer from eutrophication, caused by an overload of phosphorus (P) and nitrogen (N). In Sweden these emissions from point sources, e.g. READ MORE

  4. 12. Water transport through perinatal skin : Barrier function and aquaporin water channels

    Author : Johan Ågren; Gunnar Sedin; Gunnar Flemström; Steven B Hoath; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Preterm infant; Transepidermal water loss; Aquaporin; Skin biology; Hyperosmolarity; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Abstract : While constituting a well functioning interface with the aqueous environment in utero, the skin offers a poor barrier after very preterm birth. As a result, transepidermal water loss (TEWL) is high, a fact which has important clinical consequences in these infants. READ MORE

  5. 13. Climate Change Impacts on the Catchment Contribution to Lake Water Quantity and Quality

    Author : Karen Moore; Kurt Pettersson; Donald Pierson; Timothy Kratz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; water quality modelling; Lake Mälaren; GWLF; nutrient transport;

    Abstract : A key question related to climate change projections is how will aquatic systems respond to changes in variables such as temperature and precipitation? This thesis uses GWLF, a simple catchment scale model to explore potential impacts of climate change on water quantity and quality.River discharge and nutrient loads were modelled for several warmer world scenarios.

  6. 14. Placental transport of glucose and amino acids in early pregnancy. Cellular mechanisms, regulation and relation to diabetes

    Author : Anette Ericsson; Göteborgs universitet; []
    Keywords : placental transport; diabetes; first trimester; GLUT; system A; hyperglycemia;

    Abstract : Despite strict glycemic control of the pregnant woman with type 1 diabetes fetal overgrowth is still common. The first trimester is often characterized by sub-optimal glucose levels and elevated HbA1C in early pregnancy is a predictor of fetal overgrowth. READ MORE

  7. 15. Lake Hydrodynamics and Pollution Transport under Climate Change : The Case of Lake Victoria

    Author : Seema Paul; Henrik Ernstson; Zahra Kalantari; Abhijit Mukherjee; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bathymetry mapping; model verification; water balance; correlation; tracer transport; wind hydrodynamics; pollution and nutrient transport; climate effect; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : A very small part of the total earth’s water is freshwater (only 2.5 %). Unfortunately, due to climate change and pervasive manmade activities, surface freshwater quality in many places of the world has become degraded. READ MORE
