  2. 36. Imprint of management on microbial communities in arable soil : implications for N2O emissions

    Author : Tina Putz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Arable soils are a major source of the greenhouse gas nitrous oxide (N2O), emissions of which are directly linked to increased use of N fertilizers. Microbial communities that drive N cycle processes in soil ultimately determine the fate of reactive N inputs and control N2O emissions. READ MORE

  4. 37. Moving towards a More Sustainable World : four Essays on Renewable Energy, Emissions Trading, and Environmental Behaviour

    Author : Sandra Schusser; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Reducing industrial greenhouse gas emissions is essential to fight climate change. In addition, private consumption patterns have effects on emissions and the sustainable use of natural resources. READ MORE

  5. 38. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

    Author : Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

    Abstract : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. READ MORE

  6. 39. Diffusion of innovative domestic heating systems and multi-storey wood-framed buildings in Sweden

    Author : Krushna Mahapatra; Leif Gustavsson; Ole Jess Olsen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

    Abstract : The diffusion of innovations that promote sustainable use of forest resources and energy efficiency is important for reducing greenhouse gas emission and dependency on oil. In this thesis the ‘systems of innovation’ (SI)The SI analyses showed that several sources of path dependency, resulting from the establishment and growth of the concrete-based construction system over the past 100 years, hinder the expansion of a wood-based multi-storeyThe adopter-centric approach included household questionnaire surveys: one covering the whole of Sweden in 2004 involving 1500 randomly selected homeowners with any type of heating system, and another in the city of Östersund inThe expansion of district heating networks in the detached home sector, particularly those homes with resistance heaters, is often considered difficult.

  7. 40. Few particle effects in pyramidal quantum dots - a spectroscopic study

    Author : Daniel Dufåker; Fredrik Karlsson; Per Olof Holtz; Val Zwiller; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis two very similar processes have been studied, both involving excitations of particles during recombination of exciton complexes in quantum dots, reducing the energy of the emitted photon. Different exciton complexes are defined according to the number of electrons and holes in the quantum dot upon recombination. READ MORE
