  4. 3. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE

  5. 4. Intermediate-mass black hole binary as an origin of super-massive black holes

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

  6. 5. ”The Sea City” in Trelleborg: A climate-adapted design proposal to combat flooding from cloudbursts and rising sea levels

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Ulrica Flemström; [2023]
    Keywords : Adaptability; climate adaptation; cloudbursts; coastal protections; flooding; nature-based solutions; resilience; rising sea levels; sustainability; sustainable urban design; urban design; urban planning.; Arts and Architecture;

    Abstract : Scientific studies indicate that the effects of the ongoing climate crisis negatively affect and sometimes also threaten the built environment, humanity and nature in many ways. Cloudbursts and rising sea levels are two examples of such effects, which result in complex dilemmas and interesting challenges that planners and urban designers face within their field of work.
