  2. 1. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support

    Author : Klas Lucander; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest; boreal ecosystems; Forest biogeochemistry; Forest bioenergy; Boreal coniferous forest; base cations; Biogeochemical cycles; Dynamic Modelling; Carbon cycle; nitrogen cycle; decision support; policy-making; Weathering; Forestry; Land use change;

    Abstract : Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve.

  4. 2. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments

    Author : Danial Molavitabrizi; Mahmoud Mousavi; Kristofer Gamstedt; Haiyang Yu; Samuel Forest; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot tillämpad mekanik; Engineering science with specialization in Applied Mechanics;

    Abstract : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. READ MORE

  5. 3. Modelling and Retrieval of Forest Parameters from Synthetic Aperture Radar Data

    Author : Maciej Soja; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic Aperture Radar; biomass estimation; modelling; forest;

    Abstract : Currently, one of the most uncertain factors in the global carbon cycle models lies in the terrestrialcarbon stock, mainly forests. The available methods for global forest resource mapping provide onlyrough estimates of biomass, the most relevant practical quantity related to carbon stock. READ MORE

  6. 4. Timber as a forest-risk commodity: embodied socio-ecological impacts in the Brazilian supply chain

    Author : Caroline Sartorato Silva Franca; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Environmentally-extended input-output model; Land use; Supply chain traceability; Forest frontiers; Sustainable Forest Management SFM ; Forest degradation; Illegal logging;

    Abstract : The continued loss and degradation of forest resources is one of the largest sustainability challenges of our time. The past decades rise in global demand for agricultural and forest commodities have created unparalleled pressure on the natural resources, leading to forest destruction and associated loss in carbon stocks, invaluable biodiversity, ecosystems services, livelihoods.

  7. 5. Strain Gradient Plasticity Modelling of Precipitation Strengthening

    Author : Mohammadali Asgharzadeh; Jonas Faleskog; Samuel Forest; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The introduction of particles and precipitates into a matrix material results in strengthening effects. The two main mechanisms involved in this matter are referred to as Orowan and shearing. To numerically study this phenomenon is the motivation to the research done, which is presented here in this thesis. READ MORE
