Visar resultat 1 - 5 av 37 avhandlingar innehållade orden fibre separation.
Sammanfattning : In this thesis the orientation of macro-sized fibres in turbulent flows is studied, as well as the effect of nano-sized fibrils on hydrodynamic stability. The focus lies on enabling processes for new materials where cellulose is the main constituent. LÄS MER
- Detta är en avhandling från Sundsvall : Mid Sweden University
Sammanfattning : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. LÄS MER
3. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve functionDetta är en avhandling från Department of Plastic and Reconstructive Surgery, Malmö University Hospital, Malmö, Sweden
Sammanfattning : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. LÄS MER
- Detta är en avhandling från Department of Plastic and Reconstructive Surgery, Malmö University Hospital, Malmö, Sweden
Sammanfattning : Non-spherical particles are present all around us, in biological, industrial and environmental processes. Making predictions of their impact on us and systems in our vicinity can make life better for everyone here on earth. LÄS MER
- Detta är en avhandling från Stockholm : Royal Institute of Technology
Sammanfattning : In this thesis, wood nanotechnologies for transparent, fire-retardant and hydrophobic/lipophilic wood have been developed. There are two main parts; wood template preparation/processing concepts and materials design using these templates.In the wood template processing part, highly porous nanostructured wood templates are prepared.
