  1. 16. European Energy Policy in Transition: Critical Aspects of Emissions Trading

    Författare :Markus Wråke; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy policy; climate policy; carbon dioxide; climate change; emissions trading; EU ETS; efficiency; distributional effects; closures; new entrants; electricity; allocation; auctions; carbon leakage; competitiveness; peat; radiative forcing;

    Sammanfattning : The overarching theme of the thesis is European energy and climate policy, with a particular focus on the role of emissions trading. The thesis consists of eight papers. Paper 1 outlines the origins and characteristics of the European Union’s Emissions Trading System (EU ETS), launched in January 2005. LÄS MER

  3. 17. Perspectives from a human-centred archaeology : Iron Age people and society on Öland

    Författare :Helene Wilhelmson; begravning och social identitet Gravarkeologiska forskargruppen – Död; []
    Nyckelord :HUMANIORA; HUMANITIES; Osteology; bioarchaeology; Iron Age; Scandinavia; 3D; digital; Image Based Modeling; GIS; isotopes; Oxygen; Strontium; Carbon; Nitrogen; trophic level effect; fractionation; chronology; network; Virtual Taphonomy; human-centred archaeology; mortographies; dietary shift; integration; immigration; diet; migration; violence; burial; Viking Age; Öland; island;

    Sammanfattning : The objective of this study was to develop, test and evaluate a specifically defined interdisciplinary approach—the human-centred approach—as applied to a case study, Iron Age Öland. Four themes were selected to highlight different aspects of particular interest in Öland: taphonomy, diet, migration, and social organization. LÄS MER

  4. 18. Natural and social dimensions of forest carbon accounting

    Författare :Wilhelm Dubber; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest carbon fluxes; REDD ; boreal forest; LPJ-GUESS; BIOME-BGC; remote sensing;

    Sammanfattning : Global forests store large amounts of carbon both in living biomass and in the soil. The ability of forests to counteract climate change by acting as carbon sinks have been recognized in global climate politics, such as the 2015 Paris agreement which calls for national commitments to reduce greenhouse gas emissions.

  5. 19. Carbon Dioxide Pneumoperitoneum - Hemodynamic Consequences and Thromboembolic Complications

    Författare :Fredrik Lindberg; K G Ljungström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Laparoscopic surgery; carbon dioxide pneumoperitoneum; hemodynamics; coagulation; fibrinolysis; thromboembolic complications; phlebography; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : The laparoscopic way of performing general surgical procedures was introduced all over the Western world in a few years around 1990. No previous scientific studies of the safety of this new way of performing general surgery had been undertaken. LÄS MER

  7. 20. Achieving carbon isotope mass balance in northern forest soils, soil respiration and fungi

    Författare :Björn Boström; Alf Ekblad; Phil Ineson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 13C; Carbon cycle; Ectomycorrhizal fungi; Forest soil; Microbial respiration; Soil respiration; Stable isotopes; Biology; Biologi; Biology; Biologi;

    Sammanfattning : Northern forests contain a large part of the global terrestrial carbon pool and it is unclear whether they will be sinks or sources for atmospheric carbon if the climate warms as predicted. Stable isotope techniques provide unique tools to study the carbon cycle at different scales but the interpretation of the isotope data is impaired by our inability to close the carbon isotope mass balance of ecosystems.
