  1. 1. Effect of mixing time and mixing rate on the evolution of powderproperties for binary adhesive mixtures

    Master-uppsats, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Författare :Noveen Muslih Sadullah; [2024]
    Nyckelord :Adhesive mixture; mixing time; mixing rate; Budesonide; Lactopress SD;

    Sammanfattning : Dry powder inhalers (DPIs) are often used to deliver drugs to the lungs when treating respiratory diseases. Inhalation powders are often formulated as adhesive mixtures which is the main formulation type used for dry inhalation powders of pharmaceuticals. LÄS MER

  3. 2. The functional anatomy of the crocodilian heart

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Jennifer Karlsson; [2023]
    Nyckelord :Anatomy; Cardiac right-to-left shunt; Cog-teeth-like valves; Crocodilian heart; Foramen of Panizza; Hemodynamics; Left aorta;

    Sammanfattning : Crocodiles are ectothermic, intermittent breathing reptiles with low metabolic rates. Additionally, they are diving animals that can stay submerged for long periods, which poses special demands on their cardiovascular system. The crocodilian heart is four-chambered with completely separated ventricles, making it unique among other reptiles. LÄS MER

  4. 3. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Nadja Rabizadeh; [2023]
    Nyckelord :CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Sammanfattning : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. LÄS MER

  5. 4. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  7. 5. Polymer gel dosimetry - Using MRI-readout, simplified relatively non-toxic mixing procedure tested on FLASH

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Maria Blomstedt; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to its favorable qualities such as very high resolution, 3D coverage, tissue equivalence and independence of energy and incident direction of the radiation beam.
