26. Applications of Bayesian Econometrics to Financial Economics
Sammanfattning : This PhD thesis consists of four separate papers. What these papers have in common is that Bayesian Econometrics, in combination with Markov chain Monte Carlo (MCMC) methods, is applied to study various problems in financial economics. LÄS MER
27. Industrial applications and properties of oxalate-degrading enzymes
Sammanfattning : Oxalate-degrading enzymes were investigated with focus on potential applications in the pulp and paper industry and in active packaging. Changes introduced to make the pulp and paper industry more environmentally friendly, such as recirculation of process-water streams and elementary chlorine free bleaching of pulp, have led to increasing problems with precipitation of calcium oxalate.

28. Design of new bioresourcepackaging from wood hydrolysates
Sammanfattning : Hemicelluloses are a large group of polysaccharides that have recently attracted considerable attention in many industrial fields due to their abundance and renewability. They are non-edible and possess very good oxygen-barrier properties. LÄS MER
29. Polysaccharide thin film studies - Adsorption of oxidized xylan on cellulose
Sammanfattning : Wood xylans are renewable natural materials that have potential for future use in bio-based products. However, their high price and low production capacity restrict their industrial use and current applications. This research aimed to explore the potential of wood xylans for film applications.

30. Process intensification in mechanical pulping : Reduced process complexity and improved energy efficiency
Sammanfattning : This work shows that, for newsprint quality grades, the production processes for mechanical pulp can be simplified, and the specific electrical energy demand can be reduced with around 600 kWh/ton (30%). The purpose of the work is to demonstrate how the production cost for mechanical pulps can be decreased through increased energy efficiency and reduced number of unit operations. LÄS MER
