  3. 2. 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

  4. 3. The impact of addition of force control agent in adhesive mixtures : Effect of magnesium stearates on flowability and aerosolization properties

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Moa Erlandsson; [2023]
    Keywords : ;

    Abstract : When drugs need to be delivered to the respiratory system dry powder inhalers (DPIs) are often used. The powders in DPIs often consists of a micronized active pharmaceutical ingredient (API) that is adhered to a larger carrier particle forming an adhesive mixture. READ MORE
