1. Flow and Compression of Granulated Powders : The Accuracy of Discrete Element Simulations and Assessment of Tablet Microstructure
Sammanfattning : Simulations are powerful and important tools for gaining insight into powder processes. Ultimately, simulations have the potential to replace experiments. Thus, accurate models and insight into the essential factors for descriptions of powder behaviour are required. LÄS MER
2. Tableting performance of dry granulated particles : Significance and assessment of compression mechanical properties
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. Traumatic edema of rat spinal cord : composition, relation to degree of compression, influence of methylprednisolone, tirilazad and hypothermia
Sammanfattning : .... LÄS MER
4. Identification and Variation of some Functionality Related Characteristics of Pharmaceutically Relevant Solid Materials and their Effect on Product Performance
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
5. Compression analysis as a tool for technical characterization and classification of pharmaceutical powders
Sammanfattning : There are today strong incentives for an increased understanding of material properties and manufacturing processes to facilitate the development of new technologies in the pharmaceutical industry. The purpose of this thesis was to suggest methods requiring a low sample amount for characterization of technical properties of powders. LÄS MER
