  2. 6. Water Absorption in Two-Layer Masonry Systems - Properties, profiles and predictions

    Author : Peter Johansson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture-diffusivities; masonry; measuremets; moisture-profiles; Material technology; simulations; sorption-isotherms; Materiallära; materialteknik;

    Abstract : The main impetus for this research was the desire to verify models for determining transient moisture profiles in the capillary range. For the evaluations, transient moisture profiles were both simulated and measured, after which the results of the two methods were compared. READ MORE

  4. 7. The European forest trade model : EU policy and the impact on forest raw material use

    Author : Anna Mansikkasalo; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : The main purpose of this study is to develop a numerical simulation model of the European trade in forest fuels and analyse the possible trade levels for forest fuels in Europe following the implementation of EU energy policy. The White Paper and the RES-E Directive have been designed partly to support an increased use of forest fuels as sources for energy generation. READ MORE

  5. 8. Environmental, Resource and Health Impacts of Hard Materials

    Author : Anna Furberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFA; life cycle assessment; material flow analysis; cemented carbide; disability-adjusted life years; LCA; DALY; hard metal; tire stud;

    Abstract : The importance of hard materials for society is illustrated by the fact that entire historical time periods have been named after the predominant hard material used at that time. In the latest century, the introduction of the hard material cemented tungsten carbide with cobalt (WC-Co) has contributed to the economic growth we have seen and this material is crucial for the manufacturing industry of today.

  6. 9. Fuel dispersion and bubble flow distribution in fluidized beds

    Author : Johanna Olsson; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluidised bed; fuel mixing; bubble distribution; digital image analysis; particle tracking; Energi och material; Resource Recovery; Resursåtervinning;

    Abstract : Fluidized bed technology is used for thermal conversion of solid fuels (combustion and gasification) and is especially suitable for conversion of low-rank fuels such as biomass and waste. The performance of fluidized bed units depends on the fuel mixing and fuel-gas contact. READ MORE

  7. 10. The role of terrestrial and phytoplankton-derived organic matter in planktonic food webs

    Author : Anja Wenzel; Ann-Kristin Bergström; Tobias Vrede; Maarten Boersma; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Daphnia; phytoplankton; heterotrophic bacteria; terrestrial particulate organic material; food quality; food quantity; fatty acids; oligotrophic; Light:Nutrient-Hypothesis; limnologi; Limnology;

    Abstract : Lakes are important global ecosystems and many of them are nutrient-poor (unproductive). Especially in northern boreal latitudes, lakes may be heavily subsidized by terrestrial organic material (t-OM) from peat layers in the catchment. READ MORE
