2. 6. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective

   Author : Lisa Näslund Eriksson; Leif Gustavsson; Antti Asikainen; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; Environmental engineering; Miljöteknik;

   Abstract : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. READ MORE

4. 7. Carbon Balance Implications of Forest Biomass Production Potential

   Author : Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; forest management; silviculture; clear-cut forestry; continuous-cover forestry; substitution; total carbon; climate benefit; climate change; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. READ MORE

5. 8. Year-round production of forest seedlings under LED lamps : Biological and energetic implications of indoor cultivation

   Author : Marco Hernandez Velasco; Uwe Zimmermann; Anders Mattsson; Frank Fiedler; Johanna Riikonen; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Picea abies; Pinus sylvestris; year-round cultivation; forest seedlings; LED lamps; light quality; light quantity; daily light integral; adaptive lighting control; greenhouse integrated photovoltaics; agrivoltaics; seedling growth performance; short-day treatments; cold hardiness; light shock stress; Engineering Science; Teknisk fysik;

   Abstract : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. READ MORE

6. 9. Management of forest biomass terminals

   Author : Kalvis Kons; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Terminals and log-yards are becoming increasingly important in Nordic forest supply chains because of the need to support the rising production capacity of pulp mills and heat and power plants. Most modern terminals and log-yards handle multiple assortments, must accommodate multiple incoming and outgoing modes of transport, and have multiple storage areas. READ MORE

7. 10. A land of one's own : Sami resource use in Sweden's boreal landscape under autonomous governance

   Author : Gudrun Norstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : HUMANIORA; HUMANITIES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; HUMANIORA; HUMANITIES; ALS; archaeology; boreal forest; dendrochronology; forest history; historical maps; interdisciplinary research; lidar; Sami; settlement patterns; ALS; arkeologi; boreal skog; bosättningsmönster; dendrokronologi; historiska kartor; lidar; samer; skogshistoria; tvärvetenskap;

   Abstract : The Sami dominated large parts of boreal Sweden well into the 18th century, and knowledge of Sami subsistence patterns is therefore a key to the region’s forest history. Although much research has been done on Sami resource use and landscape impact, the context is often vaguely understood. READ MORE
