  1. 36. Effects of commercial hatchery processing on behaviour and welfare of laying hens

    Författare :Louise Hedlund; Per Jensen; Charlotta Berg; Bas Rodenburg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Around the world, more than 76.7 million tons of eggs are consumed every year. To meet this demand, billions of laying hen chicks are produced under highly industrial circum-stances. These chicks are hatched in commercial hatcheries for laying hens in a presumably stressful environment, which might affect their welfare and production later in life. LÄS MER

  3. 37. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass

    Författare :Hanbing He; Marcus Öhman; Kent Davidsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layer formation; bed particle; woody biomass; quartz; K-feldspar; olivine; bed agglomeration; deposition; fluidized bed; combustion; gasification; Energiteknik; Energy Engineering;

    Sammanfattning : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. LÄS MER
