  1. 1. Understanding Adhesive Mixtures for Inhalation : Particle Dynamics Modelling and Segregation Experiments

    Författare :Sohan Sarangi; Göran Frenning; Göran Alderborn; Kyrre Thalberg; Johannes Khinast; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inhalation; adhesive mixtures; dry powder inhaler; discrete element method; segregation; stability; modeling; Galenisk farmaci; Pharmaceutics; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Pulmonary route has been used as a source of drug delivery to lungs for centuries. Drugformulation decides the type of inhaler devices such as pressurized metered-dose inhalers(pMDIs), nebulizers and dry powder inhalers (DPIs). LÄS MER

  3. 2. Powder mechanics and dispersion properties of adhesive mixtures for dry powder inhalers : Conceptualized as a blend state model

    Författare :Jonas Rudén; Göran Alderborn; Göran Frenning; Tobias Bramer; Kyrre Thalberg; Regina Scherliess; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inhalation; Dry Powder Inhaler; adhesive mixture; aerosols; powder mechanics; dispersibility; aerosolization; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Inhaled medicines is a therapy that dates back several thousands of years. Nowadays, using various types of inhaler devices to deliver active pharmaceutical ingredients (APIs) to treat respiratory diseases has become common practice. LÄS MER

  4. 3. A Multi-Scale Approach To Adhesive Mixing

    Författare :Duy Nguyen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive particle mixing; CFD simulation; multiscale; dry particle coating; regime map.; DEM simulation; dry powders for inhalation;

    Sammanfattning : Adhesive particle mixing is a fundamental process in many applications, especially in dry powders for inhalation. Despite its importance, a mechanistic process description for designing the structure of interest is still lacking. LÄS MER

  5. 4. Mechanisms of adhesive mixing for drug particle inhalation (Numerical investigation of the interplay between formulation variables)

    Författare :Mohammadreza Tamadondar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Element Method; Agglomerate; Carrier Particle; Adhesive mixing; Dispersion; DPI-formulation;

    Sammanfattning : Formulation of therapeutic dry powders for lung drug delivery via inhalation is done via adhesive mixing. In this process, micron-sized active pharmaceutical ingredient particles are blended with relatively coarse carrier particles until stable adhesive units of carrier and drug particles are formed.

  7. 5. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors

    Författare :Rasoul Nilforoush; Lennart Elfgren; Norbert Randl; Karin Lundgren; Manouchehr Hassanzadeh; Richard Malm; Lars-Erik Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Headed anchor; Anchor bolt; Adhesive anchor; Concrete cone breakout; Concrete splitting; Pullout loading; Size effect; Member thickness; Anchor head size; Orthogonal surface reinforcement; Concrete Strength; High-strength concrete; Cracked concrete; Steel fiber-reinforced concrete; Sustained loading; Creep behavior; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. LÄS MER
