  1. 1. Management of forest biomass terminals

    Författare :Kalvis Kons; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  3. 2. Carbon Balance Implications of Forest Biomass Production Potential

    Författare :Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Estimation of Forest Biomass and Faraday Rotation using Ultra High Frequency Synthetic Aperture Radar

    Författare :Gustaf Sandberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Ultra High Frequency; Faraday Rotation; Synthetic Aperture Radar;

    Sammanfattning : Synthetic Aperture Radar (SAR) data in the Ultra High Frequency (UHF; 300 MHz – 3 GHz)) band have been shown to be strongly dependent of forest biomass, which is a poorly estimated variable in the global carbon cycle. In this thesis UHF-band SAR data from the fairly flat hemiboreal test site Remningstorp in southern Sweden were analysed. LÄS MER

  5. 4. Forest biomass terminal properties and activities

    Författare :Kalvis Kons; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Primary residual forest biomass is an important source of energy in Sweden. The fuel quality of this biomass depends on several factors including its moisture content, ash content, and particle size distribution. LÄS MER

  7. 5. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band

    Författare :Erik Blomberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Tomography; SAR; L-band; EM Modelling; P-Band;

    Sammanfattning : Forests and their associated habitats are an integral part of Earth's biosphere and provide essential environmental services. There is an ever present need for accurate and economic monitoring of forest parameters such as biomass - of great interest both locally, for forest management and resource utilization, and globally as it represents stored atmospheric CO2 and one of the largest uncertainties in climate modelling.
