1. Aspects of the Design of Preparative Chromatography for Purification of Antibodies
Sammanfattning : The development of biotechnological products is becoming more and more expensive. One type of protein attracting a great deal of attention in the biopharmaceutical industry is antibodies, which was used in this work. LÄS MER
2. Mechanistic Modelling of Drug Dissolution and Matrix Formulations: Rotating Disc Dissolution, Dissolution in a Stagnant Medium, Swelling and Dissolving Matrix Systems
Sammanfattning : Popular Abstract in Swedish Under årens lopp har människan gjort stora landvinningar inom läkemedelsforskning, vilket har lett fram till avancerade läkemedel som idag tas för givna. Avancerade läkemedel sätter dock höga krav på tillverkarna av läkemedel, vilket har lett till att framtagandet av nya läkemedel är en ganska komplicerad process. LÄS MER
3. Characterization of the Mechanisms of Drug Release from Polymer-Coated Formulations using Experiments and Modelling
Sammanfattning : The main objectives of the work presented in this thesis were to develop new experimental methods to improve the understanding of the release mechanism from a coated formulation and to develop new mechanistic models to describe the release process for pellets coated with a semi-permeable film. Another aim was to characterize the release mechanism from a formulation coated with films made of a blend of a water-insoluble polymer, ethyl cellulose (EC), and a water-soluble polymer, hydroxypropyl cellulose (HPC).

4. Combined speckle interferometry and speckle correlation for non-destructive testing
Sammanfattning : When a sample is studied during loading in a tensile test machine, the sample is often exposed to rigid body motions during loading at the same time as it deforms due to tension. Therefore, the small deformation field is hard, or impossible, to measure when it is overlaid by a large motion. LÄS MER
5. TV holography and shearography in experimental mechanics
Sammanfattning : TV holography is an optical non-contacting whole field technique to measure deformation. Names as ESPI or Electronic speckle pattern interferometry, Electro-optic holography and Electronic holography are commonly used for this real-time video based interferometric technique. Shearography has become an important tool in non destructive testing. LÄS MER
