  2. 21. Chaperone/usher machinery : a catalyst of virulence organelle assembly

    Author : Xiaodi Yu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Many virulence organelles of Gram-negative bacterial pathogens are assembled via the periplasmic chaperone/usher (CU) pathway. The assembly process is a complex task, involving secretion of organelle subunits via the two membranes and periplasm, subunit folding and assembly. READ MORE

  4. 22. Studies of ash transformation processes in thermochemical co-conversion of phosphorus-rich manure and sludge with biomass residues

    Author : Gustav Häggström; Marcus Öhman; Anders Lagerkvist; Nils Skoglund; Flemming Jappe Frandsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sewage sludge; agricultural residues; forest residues; ash transformation; potassium; phosphorus; combustion; gasification; phosphorus recovery; Energy Engineering; Energiteknik;

    Abstract : Efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus (P) present in manure and sewage sludge. READ MORE

  5. 23. Climate Impact and Energy Balance of Emerging Biorefinery Systems

    Author : Hanna Karlsson Potter; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Use of fossil fuels is the main contributor to anthropogenic emissions of greenhouse gases (GHG). Biorefineries, which are facilities that produce a set of valuable products from biomass, have been suggested as alternatives to fossil refineries, for the production of fuels, chemicals and materials.

  6. 24. Decentralised energy systems based on biomass : a life cycle perspective on climate impact and energy balance

    Author : Marie Kimming; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Replacing fossil fuels with renewable energy sources is recognised as an important measure to mitigate climate change. Residual biomass from agriculture and forestry and short-rotation coppice grown on unused land can be converted to heat, power and fuel without directly compromising production of edible crops.

  7. 25. Energy use and environmental impact of roundwood and forest fuel production in Sweden

    Author : Eva-Lotta Lindholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The increasing awareness of climate change issues, unstable fossil fuel prices and concerns about energy security are leading to a rising demand for forest products. If meeting this demand involves increased harvesting it is essential to employ efficient systems that allow sustainable forest management. READ MORE
