6. Properties and performance of environmentally adapted synthetic esters
Sammanfattning : The lubricants of the future have to be more environmentally adapted, have a higher level of performance, and lower total life cycle cost (LCC) than commonly used lubricants today. Since we live on a planet with finite resources, we have to think about coming generations and work for a sustainable development in the field of tribology. LÄS MER
7. Microstructure and Mechanical Properties of Plasma Atomized Refractory Alloys
Sammanfattning : Plasma centrifugal atomization is a method widely used in the production of spherical powders of metals and alloys with relatively low melting points. A novel plasma centrifugal atomization process suitable for high melting point materials (i.e. 3500 ᵒC and above) was developed by Metasphere Technology AB, currently Höganäs Sweden AB. LÄS MER
8. Deciphering sequence data : A multivariate approach
Sammanfattning : In this thesis, attention has been focused on the quantitative description of nucleic acids, proteins and peptides. The strategy was to use multivariate chemometrical methods for improving the understanding of the complex structural codes of these kinds of biological molecules. LÄS MER
9. Towards a new sensing strategy for measuring paper pulp properties : a combination of ultrasonic and optical measurement techniques
Sammanfattning : In the manufacturing process of paper the mass fraction and material properties of the fibres in the pulp suspension are important for the strength and quality of the finished product. The properties of the fibres in the pulp suspension that enters the paper machine is not well understood and therefore an adequate prediction of the strength and quality of the finished paper is not possible.

10. Combining limnology and paleolimnology : a refined understanding of environmental sediment signal formation in a varved lake
Sammanfattning : Paleoclimatic archives, such as lake sediments, extend our understanding of terrestrial and aquatic ecosystem dynamics in relation to climate variability beyond the period covered by instrumental data. In this context, annually laminated (i.e. LÄS MER
