1. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics
Sammanfattning : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. LÄS MER
2. Automation in forestry : development of unmanned forwarders
Sammanfattning : For the last 50 year, forestry operations have become more and more mechanized. In modern forestry in Europe two machines are typically used; a harvester that fells, debranches and cross-cuts the trees into logs and a forwarder that transports them to the nearest road. LÄS MER
3. Som man ropar i skogen : Modernitet, makt och mångfald i kampen om Njakafjäll och i den svenska skogsbruksdebatten 1970-2000
Sammanfattning : In this dissertation, the Swedish forestry debate during the last three decades of the 20th century is analysed. The contents, values and underlying assumptions of the debate are investigated from a discoursive point of view. Ideals, methods and aesthetics are analysed, as they have been expressed throughout the debate. LÄS MER
4. Gendered Performances in Swedish Forestry : Negotiating Subjectivities in Women-Only Networks
Sammanfattning : Environmental resource use is intimately intertwined with gendered power relations. Overarching ideals, governance and management are shaped by the negotiation and performance of gendered subjectivities. This thesis identifies and analyses key features of such negotiations and performances in the context of contemporary Swedish forestry. LÄS MER
5. Towards semi-automation of forestry cranes : automated trajectory planning and active vibration damping
Sammanfattning : Forests represent one of the biggest terrestrial ecosystems of Earth, that can produce important raw renewable materials such as wood with the help of sun, air and water. To efficiently extract these raw materials, the tree harvesting process is highly mechanized in developed countries, meaning that advanced forestry machines are continuously used to fell, to process and to transport the logs and biomass obtained from the forests.
