  1. 21. Tableting performance of dry granulated particles : Significance and assessment of compression mechanical properties

    Författare :Maryam Tofiq; Göran Alderborn; Ann-Sofie Persson; Josefina Nordström; Peter Kleinebudde; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dry granulation; Powder compression; Compression parameters; Granule composition; Granule structure; Granule strength; Granule fragmentation; Granule deformation; Tablet tensile strength; Loss of tabletability;

    Sammanfattning : Dry granulation (DG) is often utilized as an intermediate process during tablet manufacturing, for improving flow characteristics of the powder blend and/or reducing segregation issues related to the active pharmaceutical ingredient (API). The resulting granules exhibit typically irregular shapes with rough surfaces and their mechanical properties are related to the feeding powder and the process parameters used during the DG. LÄS MER

  3. 22. Identification and Variation of some Functionality Related Characteristics of Pharmaceutically Relevant Solid Materials and their Effect on Product Performance

    Författare :Frauke Fichtner; Göran Alderborn; Åke Rasmuson; Peter Kleinebudde; Uppsala universitet; []
    Nyckelord :Pharmaceutics; Particle size distribution; Degree of agglomeration; Amorphous lactose; Matrix agglomerates; Drug release; Compactability; Tablet tensile strength; Particle fracture strength; Surfactant; Compression; Galenisk farmaci;

    Sammanfattning : The aim of this thesis was to identify some functionality related characteristics of pharmaceutically relevant solid materials and to study the effect of their variation on processing behaviour and product performance. For this purpose, particles with different characteristics were prepared under a variety of conditions by crystal agglomeration, wet granulation and spray drying. LÄS MER

  4. 23. Design of solid dosage forms for mucosal vaccination - Investigations on the influence of excipients on product performance

    Författare :Annika Borde; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrophilic matrix tablets; osmotic pressure; protein release; freeze-drying; Vibrio cholerae; mucoadhesion; Bradford Assay; sublingual vaccine tablet; mucosal vaccination;

    Sammanfattning : Most vaccines today are liquid formulations for parental administration. However, there are several drawbacks connected to these vaccines. Since injectable vaccines only induce systemic antibody responses, they are not effective against the various pathogens that affect mucosal surfaces with poor permeability for serum-derived antibodies, e.g. LÄS MER

  5. 24. Scaffolding foreign language learners’ reading strategies using tablet computers at two secondary schools in Denmark

    Författare :Nathalie Auer; UK University of Leicester; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile learning; reading strategies; digital reading; metacognition apply to reading;

    Sammanfattning : The use of mobile devices for learning has led to an increased number of textbooks and reading materials being published in digital format. Specific digital literacies are required to take advantage of these digital texts, and students need to acquire these literacies if they are to read and learn efficiently. LÄS MER
