1. DIFFUSION OF IONS IN WOOD
Sammanfattning : Wood sourced from well managed plantations or forests, is a renewable material with many advantages over non-renewable (fossil) material, and also wood lignocelluloses are the only type of biomass that is a seasonal-independent product. In addition to direct utilization as a building material, major uses of wood are currently for making pulp and paper products, and fuel. LÄS MER
2. The flow of pulp suspensions
Sammanfattning : Large quantities of pulp suspensions are handled in the pulp and paper industry and knowledge of their flow behaviour is very important in the design and operation of process equipment. Despite this, there is still a lack of a fundamental understanding of the mechanisms of the pulp suspension flow. LÄS MER
3. Fatigue Assessment of Container Ships – a Contribution to Direct Calculation Procedures
Sammanfattning : Within the field of marine structural engineering, the introduction of new materials and material classes, the development of production techniques and new design, and new requirements imposed by authorities are examples which justify a need for continuous revisit and update of fatigue assessment methodologies of marine structures. This thesis contributes to the development and improvement of fatigue assessment methodology for ship structures. LÄS MER
4. Hydrodynamics and Heat Transfer in Vertical Falling Films with Smooth and Modified Heat-Transfer Surfaces – An Experimental and Numerical Investigation
Sammanfattning : High energy utilization efficiency is important to achieve a sustainable society. By having highly efficient heat exchangers, more energy can be recovered and reused at a lower cost. LÄS MER
5. Characterisation of an in vitro dissolution method for assessment of novel pulmonary drug delivery systems : With a focus on controlled release systems
Sammanfattning : Pulmonary drug delivery has been used for decades to treat local diseases like asthma. When using the pulmonary route to deliver drugs, several important lung features are being used, such as a large surface area available for absorption, high organ vascularization, and a thin blood-alveolar barrier.
