  1. 11. Settling Mechanisms of Valuable Metal Droplets in Iron Silicate Slag

    Författare :Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : A significant source of copper losses from pyrometallurgical copper extraction is attributed to dissolved and entrained copper in discarded slag. Entrained copper can be recovered via pyrometallurgical slag cleaning in a settling furnace where the droplets settle under gravity. LÄS MER

  3. 12. Slag Cleaning of a Reduced Iron Silicate Slag by Settling : Influence of Process Parameters and Slag Modification on Copper Content

    Författare :Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Pekka Taskinen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Copper losses; matte; speiss; fayalite slag; temperature; settling time; solid phases; industrial trial; CaO modification; Process Metallurgy; Processmetallurgi;

    Sammanfattning : During the pyrometallurgical extraction of copper, a significant part of the copper is lost with discard slag, which decreases profits, overall copper recovery, and efficiency of raw material usage. Smelting furnace slag usually has a copper content that is close to or higher than that of copper ores. LÄS MER

  4. 13. Utbildningssituationen för elever med lindrig intellektuell funktionsnedsättning : Lärares och föräldrars perspektiv

    Författare :Anna-Lena Andersson; Jenny Wilder; Jonas Almqvist; Mälardalens högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; inclusive education; transition; students with mild intellectual disability; interview; pedagogical evaluations; teachers; parents; Didactics; didaktik;

    Sammanfattning : The goal of the Swedish educational system is to offer all students a meaningful and equal education in an inclusive classroom environment. At the same time there are parallel school systems in Sweden, comprised by the Compulsory School for Students with Intellectual Disability (CSSID) and Compulsory School (CS). LÄS MER

  5. 14. The Responsible Business Person : Studies of business education for sustainability

    Författare :Pernilla Andersson; Magnus Boström; Jenny Gunnarsson-Payne; Johan Öhman; Malin Ideland; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; sustainable development; responsibility; environment; business; curriculum; teaching; discourse analysis; poststructuralism; pedagogy; classroom; Environmental Studies; Miljövetenskapliga studier;

    Sammanfattning : Calls for the inclusion of sustainable development in the business curriculum have increased significantly in the wake of the financial crisis and increased concerns around climate change. This has led to the appearance of new initiatives and the development of new teaching approaches. LÄS MER

  7. 15. Hematopoietic Serine Proteases from the Mast Cell Chymase and Tryptase Loci - a Functional and Evolutionary Analysis

    Författare :Jenny Reimer; Lars Hellman; Gunnar Nilsson; Sara Wernersson; Göran Andersson; Uppsala universitet; []
    Nyckelord :Cell and molecular biology; immune system; mast cell; basophil; mast cell chymase locus; multigene tryptase locus; serine protease; evolution; Cell- och molekylärbiologi;

    Sammanfattning : Mast cells are key effector cells in allergic and inflammatory diseases. However, their primary role is most likely in host defence against parasitic and bacterial infections. Mast cells are a particularly rich source of serine proteases. LÄS MER
