  1. 26. Mosses as mediators of climate change : implications for tree seedling establishment in the tundra

    Författare :Signe Lett; Ellen Dorrepaal; David Wardle; Marie-Charlotte Nilsson; Vigdis Vandvik; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arctic; alpine; B. pubescens; bryophytes; competition; facilitation; mosses; P. sylvestris; precipitation changes; seedlings; traits; tree line; warming;

    Sammanfattning : Alpine and arctic tree line expansion depends on the establishment of tree seedlings above the current tree line, which is expected to occur with climate warming. However, tree lines often fail to respond to higher temperatures. Other environmental factors are therefore likely important for tree seedling establishment. LÄS MER

  4. 28. Transformation through Integration : An Activity Theoretical Analysis of School Development as Integration of Child Care Institutions and the Elementary School

    Författare :Monica Nilsson; Institutionen för ekonomi och samhällsvetenskap Blekinge Tekniska Högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Integration; pre-school teacher; recreation pedagogue; schoolteacher; contradiction; expansive learning; mediation; and tool;

    Sammanfattning : This study analyzes an attempt at integration of a pre-school class, a leisure-time center and an elementary school in Sweden. The integration was organized in the form of Vertical Track which implies a successive development of groups comprising children between six and twelve years old, pre-school teachers, recreation pedagogues, and schoolteachers.

  5. 29. Automatic Analysis and Reduction of Reaction Mechanisms for Complex Fuel Combustion

    Författare :Daniel Nilsson; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydraulik; Complex fuel combustion; Reduced kinetic models; skeletal mechanism; QSSA; hydraulics; Mechanical engineering; vacuum technology; Maskinteknik; vibration and acoustic engineering; vakuumteknik; vibrationer; akustik; Physics; Fysik; Chemistry; Kemi; Fysicumarkivet A:2001:Nilsson;

    Sammanfattning : This work concentrates on automatic procedures for simplifying chemical models for realistic fuels using skeletal mechanism construction and Quasi Steady-State Approximation (QSSA) applied to detailed reaction mechanisms. To automate the selection of species for removal or approximation, different indices for species ranking have thus been proposed. LÄS MER

  7. 30. Cyanobacteria as a model system for studies of oxygenic photosynthesis and respiration

    Författare :Fredrik Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Virtually all the energy available to living organisms is derived from solar radiation. The light energy from the sun is harvested by plants, algae and phototrophic bacteria and converted to chemical energy through the process of photosynthesis.Cyanobacteria are procaryotic organisms capable of oxygenic photosynthesis.
