  1. 41. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process

    Författare :Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Jonas Alexis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; numerical simulation; inclusion behavior; CFD; clogging; deposition.;

    Sammanfattning : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. LÄS MER

  2. 42. Carbohydrate Levels and Fructan Metabolism in Barley (Hordeum vulgare L.) Leaves : effects of manipulating mineral nutrition and photosynthesis

    Författare :Changwen Wang; Björn Thorsteinsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysiologisk botanik; Physiological Botany;

    Sammanfattning : Carbohydrate levels and fructan metabolism were studied in the leaves of barley (Hordeum vulgare L. cv. Agneta) plants subjected to phosphorous (P)-deficiency, nitrogen (N)-deficiency and N-resupply following the N-deficiency. LÄS MER

  3. 43. Terrestrial Ecosystem Interactions with Global Climate and Socio-Economics

    Författare :Anders Ahlström; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. Currently it is responsible for removing 25-30% of our emissions every year, an important ecosystem service that may not persist in the long term. LÄS MER

  4. 44. The role of subsoil properties for phosphorus leaching in agricultural soils

    Författare :Helena Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Phosphorus (P) leaching from agricultural land is a large contributor to eutrophication of many surface waters and the Baltic Sea. Better knowledge of P sorption and release in the subsoil could enable the development of effective mitigation strategies for P leaching. LÄS MER

  5. 45. The boreal journey of methyl mercury : from forest harvest to black alder swamps

    Författare :Rose-Marie Kronberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The bioaccumulating neurotoxin methyl mercury (MeHg) is largely recognized as a problem in the boreal landscape. Both forest harvest sites and wetlands have been identified as MeHg sources. LÄS MER
