  2. 1. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Author : Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Abstract : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. READ MORE

  5. 3. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

    Author : Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

    Abstract : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. READ MORE

  6. 4. Functional Traits in Sphagnum

    Author : Fia Bengtsson; Håkan Rydin; Gustaf Granath; Cronberg Nils; Sari Juutinen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; peat mosses; functional traits; NPP; decay resistance; N2 fixation; desiccation resistance; climate; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

    Abstract : Peat mosses (Sphagnum) are ecosystem engineers that largely govern carbon sequestration in northern hemisphere peatlands. I investigated functional traits in Sphagnum species and addressed the questions: (I) Are growth, photosynthesis and decomposition and the trade-offs between these traits related to habitat or phylogeny?, (II) Which are the determinants of decomposition and are there trade-offs between metabolites that affect decomposition?, (III) How do macro-climate and local environment determine growth in Sphagnum across the Holarctic?, (IV) How does N2 fixation vary among different species and habitats?, (V) How do species from different microtopographic niches avoid or tolerate desiccation, and are leaf and structural traits adaptations to growth high above the water table?Photosynthetic rate and decomposition in laboratory conditions (innate growth and decay resistance) were related to growth and decomposition in their natural habitats.
