  2. 26. Process-based modelling of N losses from terrestrial ecosystems

    Author : Josefine Nylinder; Göteborgs universitet; []
    Keywords : ;

    Abstract : Nitrogen (N) loss to atmosphere and ground water can contribute to environmental destruction, by N emission as the greenhouse gas nitrous oxide (N2O) and by leaching of N to contamination and eutrophication of water. Dynamic models are important keys to increase the knowledge of ecosystems N processes. READ MORE

  4. 27. Nitrous oxide and methane emissions from storage and land application of organic fertilisers : with the focus on sewage sludge

    Author : Agnes Willén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Organic fertiliser handling contributes to greenhouse gas emissions. Through storage and field experiments, this thesis examined strategies to reduce emissions of nitrous oxide (N2O) and methane (CH4) from storage and after land application of cattle slurry (CS) and sewage sludge (SS).

  5. 28. New diagnostic approaches to monitor irrigating fluid absorption

    Author : David Piros; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Rinsing the endoscopic operating field with an irrigating solution entails the risk of absorption of the fluid. The physiological consequences of such absorption are explored and two new methods for monitoring the amount of absorption are proposed. READ MORE

  6. 29. Greenhouse gas fluxes between drained forested peatlands and the atmosphere - influence of nutrient status and wood ash fertilization

    Author : Maria Ernfors; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; greenhouse gases; peatlands wood; ash; nutrient status;

    Abstract : The management of peatlands for wood production involves drainage and, sometimes, fertilization with, for example, wood ash. The effects of these measures on greenhouse gas fluxes, in relation to the ... READ MORE

  7. 30. Soft X-ray Scattering Dynamics Close to Core Ionization Thresholds in Atoms and Molecules

    Author : Johan Söderström; Jan-Erik Rubensson; Lorenzo Avaldi; Uppsala universitet; []
    Keywords : Physics; Soft X-ray emission; Resonant inelastic X-ray scattering; Double excitations; Helium; X-ray-emission-threshold-electron coincidence; Fysik;

    Abstract : In this Thesis studies of highly excited states in gas-phase atoms and molecules (He, Ne, N2, O2, N2O and CO2) using a variety of synchrotron-radiation based techniques are presented. The three techniques used most frequently are X-ray-emission-threshold-electron coincidence (XETECO), X-ray emission spectroscopy (XES) and X-ray photoelectron spectroscopy (XPS) and they are all given a brief introduction.
