  2. 1. A Study of Propane and Propene Ammoxidation over Antimony-Vanadium-Oxide Catalysts at Steady-State and Transient Conditions

    Author : Roland Nilsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; oxidation; Ammoxidation; propane; propene; propylene; catalysis; transient response; antimony vanadium oxides;

    Abstract : Propane ammoxidation catalysts of differing Sb/V ratio and consisting of differing amounts of the V2O5, alpha-Sb2O4, and Sb0.92V0.92O4 phases were prepared. In the first paper, the structure of Sb0. READ MORE

  4. 2. The market impact of short-sale constraints

    Author : Roland Nilsson; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The thesis addresses two areas of research within financial economics: empirical asset pricing and the borderline area between finance and economics with emphasis on econometrical methods. The empirical asset pricing section considers the effects of short-sale constraints on both the stock market as well as the derivatives market. READ MORE

  5. 3. Statistical Feature Selection : With Applications in Life Science

  7. 5. Ice, wood and rocks : regulating elements in riverine ecosystems

    Author : Johanna Engström; Christer Nilsson; Roland Jansson; James Helfield; Tenna Riis; Umeå universitet; []
    Keywords : riparian zone; timber floating; river restoration; cut-off side channels; hydrochory; large wood; anchor ice; fish;

    Abstract : Riparian ecosystems are of great importance in the landscape, connecting landscape elements longitudinally and laterally and often encompassing sharp environmental gradients in ecological processes and communities. They are influenced by fluvial disturbances such as flooding, erosion and sediment deposition, which create dynamic and spatially heterogeneous habitats that support a high diversity of species.
