  1. 11. Polymer Gels as Pharmaceutical Dosage Forms : Rheological Performance and Physicochemical Interactions at the Gel-Mucus Interface for Formulations Intended for Mucosal Drug Delivery

    Författare :Helene Hägerström; Katarina Edsman; Arne Brodin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; gel; rheology; mucoadhesion; mucosal drug delivery; in situ gel; gellan gum; Carbopol; tensile strength; nasal mucosa; intranasal administration; dielectric spectroscopy; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : Drug delivery to the nasal and ocular mucosa faces several obstacles. One of these is from the effective clearance mechanisms present in the nose and eye. Polymer gels with suitable rheological properties can facilitate the absorption of poorly absorbed drugs by increasing the contact time of the drug with the mucosa. LÄS MER

  3. 12. Deformation mechanisms and load distribution in multi-phase engineering materials

    Författare :Nitesh Raj Jaladurgam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deformation mechanisms; Electron microscopy; Eutectic high entropy alloys; Load distribution; Superalloys; In-situ neutron diffraction;

    Sammanfattning : While the transition to carbon neutral technologies is still in progress, it is vital to reduce the environmental impact of existing processes. The efficiency of combustion processes for e.g. power generation and aviation can be greatly improved by increasing the operating temperature. LÄS MER

  4. 13. Nanocellulose-based materials: from colloidal assembly to functional films

    Författare :Yingxin Liu; Lennart Bergström; German Salazar-Alvarez; Orlando Rojas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials Chemistry; materialkemi;

    Sammanfattning : The assembly of nature-based nanomaterials into complex architectures is both a design principle of biological composites, e.g., wood and nacre with outstanding properties and a promising route for developing functional macroscopic materials. LÄS MER

  5. 14. Die Modalpartikeln ja, doch und schon : Zu ihrer Syntax, Semantik und Pragmatik

    Författare :Elisabet Ormelius-Sandblom; Tyska; []
    Nyckelord :HUMANIORA; HUMANITIES; sentence mood; asser; illocutionary force; ja; German modal particles; doch; schon; syntax; semantics; pragmatics; XP; adjunct of VP; non-attitudinal; non-referential; affirmative; adversative; facticity; focus-background structure; theme-rheme structure; German language and literatur; Tyska språk och litteratur ;

    Sammanfattning : The aim of this thesis is to show how modal particles can be integrated into a modular description of language where grammar and pragmatics are seen as two independent but interacting modules. The modular approach is chosen because of the problems connected with a functional approach. LÄS MER
