3. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping
Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER
4. Influence of Microstructure on Chip Formation - Machining Aero Engine Alloys
Sammanfattning : Aero engine materials such as nickel-iron and titanium based alloys are known to be very difficult to machine. They are also known to produce shear-localized chips; a type of chip which is associated with both an increase of the tool wear and the vibration levels during machining. LÄS MER
5. Improved mass accuracy in MALDI-TOF-MS analysis
Sammanfattning : Mass spectrometry (MS) is an important tool in analytical chemistry today, particularly in the field of proteomics where identification of proteins is the central activity. The focus in this thesis has been to improve the mass accuracy of MS-analyses in order to improve the possibility for unambiguous identification of proteins. LÄS MER
