  1. 1. Impact of aerosol dwell time on the survival of Mycobacterium tuberculosis

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Grisna Isabel Prensa; [2023]
    Nyckelord :;

    Sammanfattning : The airborne pathogen Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB) and claims about 1.6 million deaths annually (WHO, 2022). LÄS MER

  3. 2. 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

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Författare :Moa Erlandsson; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  5. 4. The effect of lactose fines, magnesium stearate, choice of mixer and mixing process on the performance of adhesive mixtures for inhalation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Gabriela Ponce Aparicio; [2023]
    Nyckelord :High shear mixing; low shear mixing; lactose fines; coating agent; budesonide; mixing energy; dry powder inhaler; carrier-based formulations; mixing time; adhesive mixtures; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Dry powder inhaler (DPI) formulation is a major area of interest since they are employed by the healthcare system to treat relevant chronic diseases like asthma. Previous research has established that the manufacturing process and formulation composition are key for the active pharmaceutical ingredient to reach the lungs and achieve therapeutic effects.

  7. 5. Development of methods for detection of radioactive aerosols of special importance for the ESS facility

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Carlström; [2021]
    Nyckelord :alpha spectrometry; radioactive aerosols; spectrum simulation;

    Sammanfattning : With the construction of the European Spallation Source (ESS) steadily approaching the operational phase, an environmental monitoring program will soon be implemented with the purpose of monitoring emissions. With regard to radiation safety, it is highly important to monitor alpha emitting radionuclides in aerosol form. LÄS MER
