  1. 11. Intermediate-mass black hole binary as an origin of super-massive black holes

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Isabelle Signe Maj Maria Thord; [2023]
    Nyckelord :Intermediate-mass black holes; binary; merger; hardening; encounters; Physics and Astronomy;

    Sammanfattning : Galactic nuclei contain super-massive black holes (SMBHs), nuclear stellar clusters (NSCs), or both. In the NSC, intermediate-mass black holes (IMBHs) are likely to reside and form highly eccentric binaries. Over time, the orbit of a binary could harden via interaction with surrounding low-mass stars. LÄS MER

  3. 12. Cryogenic properties of additive manufactured austenitic stainless steels for space applications

    Master-uppsats, Luleå tekniska universitet/Materialvetenskap

    Författare :Patricio Piantanida; [2023]
    Nyckelord :austenitic stainless steel; additive manufacturing; cryogenic;

    Sammanfattning : The mechanical properties of three austenitic stainless steel alloys, namely 21-6-9, 316L and a modifed 316, fabricated via laser powder bed fusion, have been studied. From the results previously obtained through tensile tests at room and cryogenic temperatures, their strength and ductility were compared against similar conventionally processed materials. LÄS MER

  4. 13. Hållfasthetsutveckling för betong med hög andel mineraliska tillsatsmaterial

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

    Författare :Jacob Brännland; Axel Andersson; [2023]
    Nyckelord :betong; cement; hållfasthet; naturliga puzzolaner; mineraliska tillsatsmaterial;

    Sammanfattning : Concrete is the most common building material in the world and is used for structures in all partsof society. As the world is facing a major transition towards more environmentally friendlycommunities, concrete needs to be adapted accordingly. LÄS MER

  5. 14. Irradiation Embrittlement on a Core Shroud from Decommissioned BWR

    Master-uppsats, KTH/Fysik

    Författare :Åsa Bjåland; [2023]
    Nyckelord :hardness; Vickers hardness test; ATT; yield strength; irradiation embrittlement; welds; hårdhet; Vickers hårdhetstest; ATT; sträckgräns; bestrålningsförsprödning; svetsar;

    Sammanfattning : Irradiation embrittlement is a problematic issue for internal structures, such as acore shroud, in a light water reactor. It is characterized by decreased ductility andtoughness, and increased yield strength and hardening due to increased dislocations. LÄS MER

  7. 15. A Balancing Act : Understanding the Gap Between Experienced Realities and The EU Policies Towards the Eradication of Trafficking in Human Beings Through an Ontological (In)Security Lens

    Master-uppsats, Malmö universitet/Institutionen för globala politiska studier (GPS)

    Författare :Lisa Vervoort; [2023]
    Nyckelord :Human Trafficking; Ontological Security; European Union;

    Sammanfattning : The issue of human trafficking is, as stated by the EU, a crime that alters the fabric of our society and is a severe violation of human rights. However, the migration crisis within the EU has fueled a rise of the right across the continent. LÄS MER
