43. Wood and fibre mechanics related to the thermomechanical pulping process
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
44. Explaining temporal variations in soil respiration rates and delta13C in coniferous forest ecosystems
Sammanfattning : Soils of Northern Hemisphere forests contain a large part of the global terrestrial carbon (C) pool. Even small changes in this pool can have large impact on atmospheric [CO2] and the global climate. LÄS MER
45. Wood fibre deformation in combined shear and compression
Sammanfattning : Mechanical pulping for producing pulps from softwood suitable for printing grade papers, like news, is a highly energy-intensive process consuming around 2000 kWh/t in electrical energy. Due to increasing energy costs and environmental issues there is a high demand for decreasing this energy consumption. LÄS MER
