  1. 1. Reconstruction of stresses in plates by incomplete Cauchy data

    Författare :Jonas Lundgren; Björn Gustafsson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : We consider an ill-posed boundary value problem from classical plate theory for the biharmonic equation. The boundary conditions involve incomplete Cauchy data on one part of the boundary and an extra condition on the other part. LÄS MER

  2. 2. International organizations as peacemakers : The evolution and effectiveness of intergovernmental instruments to end civil war

    Författare :Magnus Lundgren; Jonas Tallberg; Isak Svensson; Yoram Haftel; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; intergovernmental organizations; international organizations; conflict management; conflict resolution; mediation; civil war; armed conflict; institutional design; mediator bias; bargaining theory; statsvetenskap; Political Science;

    Sammanfattning : Across four self-contained essays, this dissertation seeks to identify which features make international organizations (IOs) effective peacemakers in modern civil wars. The first essay introduces an original dataset on the institutional design of 21 peace-brokering IOs between 1945 and 2010. LÄS MER

  3. 3. Interplay between hormones, nutrients and adipose depots in the regulation of insulin sensitivity : an experimental study in rat and human adipocytes

    Författare :Magdalena Lundgren; Jan Eriksson; Jonas Burén; Eva Degerman; Umeå universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adipose tissue; cAMP; glucocorticoids; glucose; insulin; insulin resistance; lipolysis; subcutaneous fat; type 2 diabetes; visceral fat; Medicine; Medicin;

    Sammanfattning : Obesity and specifically central obesity is related to insulin resistance, type 2 diabetes and other components of the so-called metabolic syndrome. The aim of this study was to elucidate the interplay between hormones, nutrients and adipose depots in normal and insulin-resistant fat cell metabolism. LÄS MER

  4. 4. Evaluation of emerging forest-industry integrated biorefineries : Exploring strategies for robust performance in face of future uncertainties

    Författare :Jonas Zetterholm; Elisabeth Wetterlund; Lundgren Joakim; Johanna Mossberg; Yawer Jafri; Damiana Chinese; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; Biomass; Forest industry; Biofuels; Investment; Gasification; Fast pyrolysis; Energiteknik; Energy Engineering;

    Sammanfattning : Biorefineries have been promoted to reduce dependency on fossil resources, increase self-sufficiency, and revitalise rural areas. Commercial deployment of forest-based biorefineries has been slow, although academic research has identified several technology options as promising in terms of both costs and resource usage.

  5. 5. Forest based biorefinery supply chains - Identification and evaluation of economic, CO2, and resource efficiency

    Författare :Jonas Zetterholm; Elisabeth Wetterlund; Joakim Lundgren; Pettersson Karin; Johanna Mossberg; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Biorefineries for production of fuels, chemicals, or materials, can bean important contribution to reach a fossil-free economy. Large-scaleforest-based biorefineries are not yet cost competitive with their fossil counterparts and it is important to identify biorefinery supply chain configurations with good economic, CO2, and biomass performance if biorefineries are to be a viable alternative to the fossil refineries.
