    Författare :Jonathan Fagerström; Christoffer Boman; Dan Boström; Marcus Öhman; Bengt-Johan Skrifvars; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; biomass; thermochemical fuel conversion; combustion; fine particle emissions; slag formation; fixed-bed; ash chemistry; fuel engineering; release;

    Sammanfattning : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. LÄS MER

  5. 4. Attached Bacterial Communities in Lakes – Habitat-Specific Differences

    Författare :Ann-Louise Haglund; Lars Tranvik; Helmut Fischer; Bengt Boström; Erik Törnblom; Paul del Giorgio; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; bacteria; freshwater; sediment; epiphyton; bacterioplankton; metabolically active; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : For many years, the importance of microorganisms attached to surfaces in littoral zones and wetlands has been disregarded when describing aquatic ecosystem dynamics. Supporting evidence is scarce but convincing that these microbial communities are not only very productive but can often serve as major regulators of nutrient and carbon dynamics in many freshwaters.

  7. 5. Climate Effects on Phytoplankton Biomass and Functional Groups

    Författare :Hampus Markensten; Donald Pierson; Kurt Pettersson; Bengt Boström; Colin Reynolds; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Climate change; phytoplankton; chlorophyll a; Lake Mälaren; Galten; PROTBAS; numerical modeling; water quality; succession; shallow lake; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Future climate in temperate regions is projected to get warmer and in many cases wetter. This poses questions about how phytoplankton in our lakes will respond. LÄS MER
