1. Birch Stem and Wood Traits in Genetic and Silviculture Trials in Southern Sweden
Abstract : Swedish tree species of birch (silver: Betula pendula and downy: B. pubescens) are often neglected during forest management activities, resulting in low value logs. This thesis investigated birch stem characteristics and wood properties important for solid wood products, in genetics and management trials in southern Sweden. READ MORE

3. Chemical Interactions between Fatty Acids and Wood Components during Oxidation Processes
Abstract : Fatty acids auto-oxidation on wood is proposed to follow a complex free radical interaction mechanism. The aim of this study was to analyze the effect of wood constituents on oxidation of fatty acids and thereby the entire drying process, and to characterize the fatty acids-wood interaction by using analytical instruments such as RT-IR and NMR.

4. Process intensification in mechanical pulping : Reduced process complexity and improved energy efficiency
Abstract : 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. READ MORE
