  2. 21. Insect diversity on clearcuts in boreal forest landscapes

    Author : Diana Rubene; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Intensive management and loss of natural disturbance dynamics in boreal forests leads to habitat loss and degradation for forest dwelling species. As a consequence, many species have become threatened, especially those dependent on dead wood. READ MORE

  4. 22. Methods for the Evaluation of Wingsails with a Crescent-Shaped Profile

    Author : Heng Zhu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind-assisted ship propulsion; rigid wingsail; light weight structure; crescent-shaped profile; wind-assisted ship propulsion.;

    Abstract : Seaborne transportation accounts for a large proportion of greenhouse gas (GHG) emissions. The International Maritime Organization (IMO) has stipulated that GHG emissions should be reduced by 50% before 2050 compared to 2018. The use of wind-assisted ship propulsion (WASP) is considered one of the most effective ways to reduce GHG emissions. READ MORE

  5. 23. Links between activation and cytoskeletal regulation of B lymphocytes

    Author : Gediminas Greicius; Edvard Smith; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoological Developmental Biology; zoologisk utvecklingsbiologi;

    Abstract : Interplay between adhesion molecules and the cytoskeleton is involved in many aspects of B lymphocyte behaviour during an immune response. Events such as cell polarisation and locomotion, collaboration with T lymphocytes and segregation in secondary lymphoid tissues all include mechanisms that recognise microenvironment and accordingly adjust morphological features of the cell.

  6. 24. Reinforcement Learning for Improved Utility of Simulation-Based Training

    Author : Johan Källström; Fredrik Heintz; Erik Herzog; Julian Togelius; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Team training in complex domains often requires a substantial number of resources, e.g. vehicles, machines, and role-players. For this reason, it may be difficult to realise efficient and effective training scenarios in a real-world setting. READ MORE

  7. 25. Signaling pathways in the activation and proliferation of Drosophila melanogaster blood cells

    Author : Carl-Johan Zettervall; Marie Meister; Umeå universitet; []
    Keywords : innate immunity; cellular immunity; molecular signaling; molekylärbiologi; Molecular Biology;

    Abstract : The larva of the fruit fly Drosophila melanogaster is an excellent model to study the molecular control of innate cellular immune responses. Cellular responses take place, and can be studied, following infestation of the wasp Leptopilina boulardi. This response includes proliferation and activation (differentiation) of the blood cells (hemocytes). READ MORE
