  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

  4. 3. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Viktor Lange; [2023]
    Nyckelord :Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER

  5. 4. DRY POWDER FOR INHALATION - INFLUENCE OF MIXING PROCESS AND ADDITION OF MAGNESIUM STEARATE

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

    Författare :Love Ivarsson; [2023]
    Nyckelord :inhalation; drug delivery; pulmonary drug delivery; API; FPF; FPD; DD; Turbula; Diosna; mixing energy; mixing time; mixing speed; pharmaceutical technology; Medicine and Health Sciences;

    Sammanfattning : For efficient treatment of many diseases of the lung, it is beneficial to deliver the medicine to the respiratory tract directly. This ensures a rapid response since it can enter the bloodstream directly through the alveolar epithelium. Consequently, also decreases systemic effects due to the local treatment. LÄS MER

  7. 5. Study of the effects of the operating conditions of a decanter centrifuge on a pilot-scale protein recovery setup from cold-pressed rapeseed press cake

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

    Författare :Sergio de La Cruz Padilla; [2023]
    Nyckelord :By-product; Rapeseed press cake; protein; Food engineering; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : There is significant evidence to suggest that diets that include high levels of meat consumption have negative effects on both the environment and human health. As a result, efforts are being made to identify and characterize more plant-based proteins, such as those found in rapeseed. LÄS MER
