  4. 3. Towards sustainability in additive manufacturing: material and process aspects

    Författare :Tatiana Fedina; Frank Brückner; Alexander Kaplan; Fabian Riss; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : The acceptance of additive manufacturing (AM) depends on the quality of final parts and process repeatability. Recently, many studies have been dedicated to the establishment of the relationship between the process behavior and material performance. LÄS MER

  5. 4. Minnesrörelser

    Författare :Helga Krook; Ingrid Elam; Gunnar D Hansson; Arne Melberg; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; litterär gestaltning; konstnärlig forskning; berättande; minne; arkiv; dokument; författaren; läsaren; översättning; museum; nazistisk eutanasi ; flod; dotter; biografi; Kreativt skrivande; Creative writing; Literary composition; artistic research; narration; memory; authorship; readership; document; archive; translation; museum; Nazi euthanasia; family album; daughter; river; biography;

    Sammanfattning : The starting point of the doctoral project Minnesrörelser (Movements of Memory) is a documentary material, based on interviews, archival documents, letters, diaries and more, from Germany and Sweden from the 1930's to present time, focusing on childhood, upbringing, eugenics, bilingualism. The family as a place for historical writing, family stories inevitably connected with political history, and how they can be passed on or kept secret makes up the main subject matter, where questions of memory and postmemory, heritage and transgenerational consequences of terror, war and guilt, as well as the role of silence, speaking and translation, are investigated.
