  1. 1. Effects of seed size and habitat on recruitment patterns in grassland and forest plants

    Författare :Karin Lönnberg; Ove Eriksson; Per Milberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seed size; seedling establishment; seedling survival; recruitment; seed removal; co-existence; game-theory; Plant Ecology; växtekologi;

    Sammanfattning : A trade-off between seed size and seed number is central in seed ecology, and has been suggested to be related to a trade-off between competition and colonization, as well as to a trade-off between stress tolerance and fecundity. Large seeds endure hazards during establishment, such as shading, drought, litter coverage and competition from other plants, better than do small seeds, due to a larger amount of stored resources in the seed.

  4. 3. Investigation of degradation of toxic substances in fungal cultures by mass spectrometric techniques

    Författare :Åke Stenholm; Mikael Hedeland; Pablo Campo Moreno; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; UHPLC-Q-TOF MS; filamentous fungi; immobilization; polyurethane foam; removal; biodegradation products; Analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : Micropollutants in water are biological or chemical contaminants that are present in ground and surface waters in trace quantities. They are a result of human activity and include pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs). LÄS MER

  5. 4. Biomass-fuelled PEM FuelCell systems for small andmedium-sized enterprises

    Författare :Tingting Guan; Per Alvfors; Mohsen Assadi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PEMFC; renewable hydrogen production; biomass; hydrogen-rich gas; biomass conversion; anaerobic digestion; steam reforming; CO removal; gasification; sustainable energy system;

    Sammanfattning : Biomass-fuelled proton exchange membrane fuel cells (PEMFCs) offer asolution for replacing fossil fuel for hydrogen production. Through using thebiomass-derived hydrogen as fuel, PEMFCs may become an efficient andsustainable energy system for small and medium-sized enterprises. LÄS MER

  7. 5. Co-combustion of Biomass and Waste Fuels in a Fluidised Bed Boiler - Fuel Synergism

    Författare :Anna-Lena Elled; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-combustion; fluidised bed combustion; straw; municipal sewage sludge; deposit formation; ash composition; biomass; wood;

    Sammanfattning : The objective of this work was to study co-combustion of biomass and waste fuels in a circulating fluidised bed boiler and to detect synergy effects with respect to flue gas composition and ash formation during boiler operation. It was also the aim to perform supplementary thermodynamic equilibrium calculations in order to support the experimental results. LÄS MER
