  2. 11. Mathematical Modelling of Insulin Signalling : Effects on Glucose Metabolism in Skeletal Muscle

    Author : Peter Sögård; Högskolan i Skövde; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Naturvetenskap; Natural sciences;

    Abstract : The use of models to understand complex phenomena is indispensable to the scientific community. The advantage of a model is that it simplifies the phenomena under study. However, a model should be only as complex as required, no more, no less. READ MORE

  4. 12. Environmental and climatic changes in the Baltic Sea and the eastern Mediterranean Sea : as recorded by pigments and isotopes in sediments

    Author : Johanna Borgendahl; Rolf Hallberg; Joyanto Routh; Stefano Bernasconi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap;

    Abstract : This thesis is a study of Holocene sapropels from two semi-enclosed seas; the Baltic Sea and the Mediterranean Sea. Sapropels are sedimentary layers with organic C > 2%. READ MORE

  5. 13. On benthic fluxes of phosphorus in the Baltic Sea proper – drivers and estimates

    Author : Nils Ekeroth; Sven Blomqvist; Per Hall; Volker Brüchert; Brita Sundelin; Jonas Gunnarsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine Ecology; marin ekologi;

    Abstract : This Thesis focuses on the exchange of phosphorus (P) across the sediment–water interface in the Baltic Sea proper, with particular attention to the influence of bioturbating macrofauna and benthic redox conditions. Benthic P fluxes have major influence on P availability in the water column, which in turn regulates growth conditions for dinitrogen fixating cyanobacteria in the Baltic proper. READ MORE

  6. 14. Carbon trace gas dynamics in subarctic lakes

    Author : Joachim Jansen; Patrick Crill; Andreas Lorke; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lakes; methane; carbon dioxide; fluxes; gas transfer; proxy; climate change; geokemi; Geochemistry;

    Abstract : Northern lakes are important sources of greenhouse gases carbon dioxide and methane to the atmosphere. Emissions are expected to increase as the climate continues to warm. Even so, lake carbon budgets are currently poorly constrained. This is in part because of a limited understanding of the processes that govern the flux. READ MORE

  7. 15. Respiratory activity in medulla oblongata and its modulation by adenosine and opioids

    Author : Eric Herlenius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adenosine; opioids; brainstem; perinatal rat; respiration; medulla oblongata;

    Abstract : From the moment of birth the complex neuronal networks generating breathing has to function continuously and adapt to the new postnatal environmental demands. This thesis aims at studying the perinatal development of respiratory control and its modulation by adenosine and opioids. READ MORE
