  2. 1. The hidden life of plants : fine root dynamics in northern ecosystems

    Author : Gesche Blume-Werry; Roland Jansson; Ann Milbau; Scott D. Wilson; Isla Myers-Smith; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; belowground; boreal; climate change; fine roots; heath; meadow; minirhizotron; permafrost; phenology; plant community; root biomass; root growth; root litter; root production; subarctic; tundra;

    Abstract : Fine roots constitute a large part of the primary production in northern (arctic and boreal) ecosystems, and are key players in ecosystem fluxes of water, nutrients and carbon. Data on root dynamics are generally rare, especially so in northern ecosystems. READ MORE

  4. 2. Experimental Investigation of Refrigerant Charge Minimisation of a Small Capacity Heat Pump

    Author : W. Primal D. Fernando; Björn Palm; Alberto Gavallini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat pump; propane; low-charge; Wilson plot method; minichannels; aluminium heat exhangers; single.phase flow; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Abstract : Enormous quantities of heat are available in air, soil, water, exhaust air from buildings, and in waste water of any kind. However these heat sources are use-less for heating purposes since their temperatures are lower than the tempera-ture required for heating. READ MORE

  5. 3. Development of robotic instruments and techniques for space and astrobiological exploration and research

    Author : Thasshwin Mathanlal; Javier Martin-Torres; Maria-Paz Zorzano Mier; Anshuman Bhardwaj; Colin Wilson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric science; Atmosfärsvetenskap;

    Abstract : Astrobiology is the study of life in the universe. The search for life beyond the Earth requires an understanding of the signatures of life, and of the nature of the environments that support it. Space exploration is a crucial factor to achieve these goals. READ MORE

  6. 4. Key Notes on the Unruly City : Social, Material, and Spatial Transgressions

    Author : Adam Bergholm; Catharina Gabrielsson; Robin Wilson; KTH; []
    Keywords : Right to the City; Art; Technology and Design; Konst; teknik och design;

    Abstract : This research departs from three intersecting field studies in Berlin, Copenhagen, and Paris, and includes both my interventions in the urban texture and integrations with existing communities working in the subject field of the Right to the City (Lefebvre 1968). The projects explore the mutable “nature” of cities and build on political philosophies which describe egalitarian actions that have shaped what those places could be. READ MORE

  7. 5. Non-conformal gauge/string duality : A rigorous case study

    Author : Xinyi Chen-Lin; Konstantin Zarembo; Jorge Russo; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AdS CFT correspondence; holographic principle; supersymmetric localization; Wilson Loops; Theoretical Physics; Teoretisk fysik;

    Abstract : The gauge/string duality, a.k.a. the holographic principle is a profound assertion that emerged from string theory. READ MORE
