  2. 1. Spray drying of particles intended for inhalation - Investigation of significant process variables and product characteristics, with focus on degradation and solid state properties

    Author : Kristina Mosén; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Läkemedelsteknik och relaterad teknik; Pharmaceutical and related technologies; carbohydrate; insulin; process conditions; crystallinity; degradation; particle size; spray drying; inhalation;

    Abstract : The interest in spray drying for production of inhalable particles has grown considerably since the late 1980s. However, which process variables that control degradation and the solid state properties have not been subject to extensive research. This thesis deals with how important characteristics of inhalation particles can be controlled, i.e. READ MORE

  4. 2. Simulations of Semi-Crystalline Polymers and Polymer Composites in order to predict Electrical, Thermal, Mechanical and Diffusion Properties

    Author : Fritjof Nilsson; Mikael Hedenqvist; Gerhard Goldbeck; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Several novel computer simulation models were developed for predicting electrical, mechanical, thermal and diffusion properties of materials with complex microstructures, such as composites, semi-crystalline polymers and foams. A Monte Carlo model for simulating solvent diffusion through spherulitic semicrystalline polyethylene was developed. READ MORE

  5. 3. Viscous-brittle deformation of shallowly emplaced silicic magma : Implications for outgassing and volcanic hazards

    Author : Taylor Witcher; Steffi Burchardt; Edward Llewellin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magma deformation; magmatic outgassing; magmatic intrusions; rhyolite; Sandfell laccolith; crystal mush; volcanic hazards; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : Silicic magma in the shallow crust has the potential to violently erupt, depending on its ability to release overpressures caused by magmatic volatiles (outgassing). Deformation-induced outgassing is prevalent along volcanic conduit margins, where ascending magma is sheared at high rates. READ MORE
