11. Efficiency of accumulating felling heads and harvesting heads in mechanized thinning of small diameter trees
Sammanfattning : .... LÄS MER
12. Establishment and early management of young forest in Sweden : stand structure, spatial design and pre-commercial thinning
Sammanfattning : Demands on forests have shifted from one (production) to multiple ecosystem services. New management strategies need to be developed to balance production and other services. In this thesis, I evaluate alternative forest management strategies to balance production, profit, and multiple ecosystem services. LÄS MER
13. Improved harvesting technology for thinning of small diameter stands : impact on forest management and national supply of forest biomass
Sammanfattning : Forest biomass is used as feedstock for forest products as well as for bioenergy. The current Swedish roundwood utilization is near the sustainable maximum. LÄS MER
14. Numerical Studies of Mixing in Pipes and Static Mixers
Sammanfattning : The objective of the present work was to investigate the mixing process in static mixers under laminar flow conditions, and in pipes during the displacement of dissimilar liquids. A numerical scheme and a method of characterizing static mixers were developed. LÄS MER
15. Silviculture of oak for high-quality wood production : effects of thinning on crown size, volume growth and stem quality in even-aged stands of pedunculate oak (Quercus robur L.) in Northern Europe
Sammanfattning : Oak is one of the most valuable noble hardwood species in Europe. The production of high-quality wood is associated with long rotations and high labour costs. LÄS MER
