  1. 6. Sampling from large flotation cells : An invastigation of spatial distribution

    Författare :Lisa Malm; Jan Rosenkranz; Tommy Karlkvist; Anders Sand; Nils-Johan Bolin; Pertti Lamberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flotation; sampling; Mineral Processing; Mineralteknik;

    Sammanfattning : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. LÄS MER

  3. 7. Deformation mechanisms and load distribution in multi-phase engineering materials

    Författare :Nitesh Raj Jaladurgam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deformation mechanisms; Electron microscopy; Eutectic high entropy alloys; Load distribution; Superalloys; In-situ neutron diffraction;

    Sammanfattning : While the transition to carbon neutral technologies is still in progress, it is vital to reduce the environmental impact of existing processes. The efficiency of combustion processes for e.g. power generation and aviation can be greatly improved by increasing the operating temperature. LÄS MER

  4. 8. Variety in Distribution Networks: A Transvection Analysis

    Författare :Kajsa Hulthén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marketing channels; network; distribution; sorting; transformation; variety; transvection;

    Sammanfattning : In recent years, the debate concerning changes taking place in distribution structures has been intense in both academia and in practice. One main standpoint is that distribution is subject to considerable reorganisation. LÄS MER

  5. 9. The Birka Warrior : the material culture of a martial society

    Författare :Charlotte Hedenstierna-Jonson; Lena Holmquist Olausson; Heinrich Härke; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Birka; martial society; warrior; material culture; distribution patterns; cultural expression; Rus’; Viking Age; Early Middle Age; iconography; style; Archaeology; Arkeologi;

    Sammanfattning : This is a study of martial material culture in the context of the Viking Age warrior of Birka, Sweden. The aim is to establish the role, function and affiliation of the Birka warrior and thereby place Birka on the power-political map of the 10th century. LÄS MER

  7. 10. Eutectic Modification of Al-Si casting alloys

    Författare :Jenifer Barrirero; Frank Mücklich; Magnus Odén; Franz Jospeh Feikus; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Aluminum alloys with silicon as the major alloying element are the most widely used aluminum casting alloys. The eutectic phase in these alloys is formed by hard and brittle silicon plates in an aluminum matrix. Such silicon plates can act as crack propagation paths deteriorating the toughness of the material. LÄS MER
