  1. 11. Essays in empirical finance

    Författare :Magnus Andersson; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Financial market analysis nowadays constitutes an important pillar in central banks' monetary policy considerations. This is because the inherently forward-looking properties of asset prices can provide policy-makers with valuable information about future macroeconomic prospects, as seen through the eyes of investors.

  3. 12. Sphagnum limits : Physiology, morphology and climate

    Författare :Charles Campbell; Håkan Rydin; Gustaf Granath; Sebastian Sundberg; Bengt-Gunnar Jonsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sphagnum; ecology; bryophyte; winter; species distribution models; low temperature; plant structure; water economy; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

    Sammanfattning : Sphagnum is the most important plant genus in terms of terrestrial carbon cycling. It and the habitats it creates store an equivalent of ~68% of the CO2 in the atmosphere. The genus has little dispersal limitation and the mire habitats are functionally similar at global scales. LÄS MER

  4. 13. On Battery Electric Vehicles: Driving Patterns, Multi-Car Households and Infrastructure

    Författare :Niklas Jakobsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEV; battery size; individual movement pattern.; Electro-mobility; GPS-logging;

    Sammanfattning : The transportation sector is responsible for a quarter of all greenhouse gas emissions in Europe. Though the transport system may be difficult to change into a less polluting system, electric vehicles may be a possible approach. LÄS MER

  5. 14. Methods for Characterization of the Diesel Combustion and Emission Formation Processes

    Författare :Mikael Lindström; Hans-Erik Ångström; Werner Hentschel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diesel engine emissions; SRA - Energy; SRA - Energi;

    Sammanfattning : In this thesis various aspects of the diesel engine fuel injection, combustion and emission formation processes have been evaluated. Several types of evaluation tools and methods have been applied. Fuel spray momentum was used to characterize injection rate and hole-to-hole variations in fuel injectors. LÄS MER

  7. 15. Relations between soil organic carbon, soil structure and physical processes in an agricultural topsoil : The role of soil mineral constituents

    Författare :Jumpei Fukumasu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : A better understanding of the interactions between soil organic carbon (SOC) and mineral constituents (e.g. clay and reactive oxide phases) and their consequences for soil structure and physical processes is important for assessing the potential for, and benefits of, carbon sequestration in arable soils.
