  2. 1. Alternative Measures of Phonation: Collision Threshold Pressure and Electroglottographic Spectral Tilt : Extra: Perception of Swedish Accents

    Author : Laura Enflo; David House; Jonas Beskow; Sten Ternström; Francisco Lacerda; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Abstract : The collision threshold pressure (CTP), i.e. the smallest amount of subglottal pressure needed for vocal fold collision, has been explored as a possible complement or alternative to the now commonly used phonation threshold pressure (PTP), i.e. READ MORE

  4. 2. Lung mechanics and airway inflammation in murine models of asthma

    Author : Sofia Jonasson; Josephine Hjoberg; Hedenstierna Göran; Carl Persson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergic asthma; airway inflammation; murine models; lung mechanics; forced oscillation technique; airway reactivity; deep inhalations; oxidative stress; nitric oxide; glucocorticoids.; Clinical physiology; Klinisk fysiologi; klinisk fysiologi; Clinical Physiology;

    Abstract : Allergic asthma is an inflammatory disease of the airways and is characterized by eosinophilic inflammation and increased airway reactivity. In the studies presented in this thesis, lung mechanics and measurements of airway reactivity were assessed in anaesthetized tracheostomized mice by using an animal ventilator (flexiVent®).

  5. 3. Studies on structure and mechanism at formation of solid solutions and solid dispersions of hydrophobic drugs in polymers

    Author : Marie Wulff; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry; fysikalisk och oorganisk farmaceutisk kemi;

    Abstract : The aim of the studies was to investigate the structures formed and mechanisms involved, when a hydrophobic drug is dispersed in a polymer carrier. The effect of different additives, like surfactants and cyclodextrins, was evaluated. The dispersions were prepared by the melting method. READ MORE

  6. 4. Utilization of Decomposition Techniques for Analyzing and Characterizing Flows

    Author : Christian Carlsson; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decomposition techniques; Proper orthogonal decomposition; Dynamic mode decomposition; Extended dynamic mode decomposition; Swirl switching; Swirling flow; Low swirl burner; Fluid-structure interaction;

    Abstract : This thesis presents the utilization of two different decomposition techniques, proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), for enhanced understanding of flow structures and their stability. The advantages of these techniques are shown for a range of flow situations, most of which are turbulent. READ MORE

  7. 5. Quantum dynamics of spin active and d-wave Josephson junctions

    Author : Jens Harro Michelsen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Josephson effect; macroscopic quantum tunneling; high-temperature superconducvity; superconducting junctions; spin-active junctions; nonequilibrium superconductivity; Andreev bound states;

    Abstract : Conventional tunnel Josephson junctions form the basic building blocks of superconducting electronics. Their operation is based on comparatively simple dynamics where the superconducting phases across the junctions is the only dynamical degree of freedom. READ MORE
