  2. 11. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field

    Author : Zsofia Réka Stangl; Vaughan Hurry; Lisa Ainsworth; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Abstract : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. READ MORE

  4. 12. Sensitivity and Uncertainty Analysis of Boiling Water Reactor Stability Simulations

    Author : Ivan Gajev; Weimin Ma; Tomasz Kozlowski; Kostadin Ivanov; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; SRA - Energy; SRA - Energi;

    Abstract : The best estimate codes are used for licensing of Nuclear Power Plants (NPP), but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. READ MORE

  5. 13. Sensitivity and Uncertainty Analysis of BWR Stability

    Author : Ivan Gajev; Tomas Lefvert; Paolo Vinai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; Engineering physics; Teknisk fysik; SRA - Energy; SRA - Energi;

    Abstract : Best Estimate codes are used for licensing, but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. READ MORE

  6. 14. Peatland dynamics in response to past and potential future climate change : A regional modelling approach

    Author : Nitin Chaudhary; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PEATLANDS; PERMAFROST; Carbon accumulation; Microtopography; LPJ-GUESS; Earth system models;

    Abstract : The majority of the northern peatlands developed during the Holocene as a result of a positive mass balance between net primary productivity (NPP) and heterotrophic decomposition rates. Over that time they have sequestered a huge amount of carbon in terrestrial ecosystems. READ MORE

  7. 15. Thrombin activatable fibrinolysis inhibitor (TAFI) in different hemorrhagic and thrombotic conditions

    Author : Jovan P Antovic; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Thrombin activatable fibrinolysis inhibitor TAFI ; coagulation; fibrinolysis; thrombin; plasmin; factor V Leiden; hemophilia; von Willebrand disease; diabetes mellitus; preeclampsia;

    Abstract : Until recently the coagulation and fibrinolytic systems were usually considered as separate entities. Accounts of a fibrinolysis inhibitor that is generated by thrombin shed more light on this field and changed the concept by giving thrombin, the pivotal enzyme in hemostasis, another important role in the down-regulation of fibrinolysis.
