  1. 11. Modelling nitrogen balance in two Southern Swedish spruce plantations

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Johannes Loer; [2016]
    Nyckelord :maximum bearable nitrogen input rate; atmospheric deposition; nitrogen saturation; forest fertilisation; ForSAFE; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Sammanfattning : Emissions from agriculture and the combustion of fossil fuels increase the atmospheric load of reactive nitrogen (N). N deposition is projected to continue posing significant harm both for environmental and human health over the upcoming decades. Eutrophication as a result of N leaching is one of the negative effects of heavy deposition. LÄS MER

  3. 12. The impact of climate change on aquatic systems and phytoplankton communities : A quantitative study of the impacts of altering food-quality on microzooplankton growth rate

    Kandidat-uppsats, Institutionen för ekologi, miljö och botanik

    Författare :Linnéa Joandi; [2013]
    Nyckelord :Climate change; phytoplankton communities; microzooplankton; B. Plicatilis; Euplotus sp.; P-limitation; N-limitation; nutrient replete conditions;

    Sammanfattning : A global increase in atmospheric CO2 and temperature is assumed to affect the marine ecosystems in numerous ways, e.g. by altering ocean circulation patterns and changing nutrient regimes. The changes are expected to impact heavily on both phytoplankton communities as well as the rest of the marine food-web. LÄS MER

  4. 13. Methane Oxidation in three Swedish Forest Soils

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Kwesi Idun Osam; [2012]
    Nyckelord :methane; oxidation; forest; soils; methanotrophs; multi-carbon compounds; consumption;

    Sammanfattning : Aerated soils are the largest sinks of atmospheric methane on the Earth’s surface. Methane removal from the atmosphere is performed through oxidation by microorganisms (methaneoxidising bacteria) in the soil. LÄS MER

  5. 14. Growth and characterization of HfON thin films with the crystal structures of HfO2

    Master-uppsats, Plasma och beläggningsfysik

    Författare :Bo Lü; [2011]
    Nyckelord :hafnium dioxide; thin films; gate dielectric; nitrogen incorporation; dielectric constant; crystal structure; HIPIMS; magnetron sputtering;

    Sammanfattning : HfO2 is a popular replacement for SiO2 in modern CMOS technology. It is used as the gate dielectric layer isolating the transistor channel from the gate. LÄS MER

  7. 15. Growth and Characterization of ZnO Nanostructures

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Abdul Samad Syed; [2011]
    Nyckelord :PL photoluminescence ; Zinc Oxide ZnO ; optical properties; temperature dependent PL; Low temperature PL; Nanostructure; epitaxial film;

    Sammanfattning : A close relation between structural and optical properties of any semiconductor material does exist. An adequate knowledge and understanding of this relationship is necessary for fabrication of devices with desired optical properties. LÄS MER
