   Sammanfattning : Lichens are fascinating symbiotic systems, where a fungus and a unicellular alga, most often green (bipartite green algal lichens; 90% of all lichens), or a fi lamentous cyanobacterium (bipartite cyanobacterial lichens; 10% of all lichens) form a new entity (a thallus) appearing as a new and integrated organism: in about 500 lichens the fungus is associated with both a cyanobacterium and an alga (tripartite lichens). In the thallus, the lichen bionts function both as individual organisms, and as a symbiont partner. LÄS MER

3. 17. Assessment of Concrete Bridges : Models and Tests for Refined Capacity Estimates

   Författare :Niklas Bagge; Anders Carolin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : Optimising the strategy for repairing, upgrading and replacing bridges in the European Union, and elsewhere, is becoming increasingly important due to ageing of the bridge stock, continuously increasing load requirements and budgetary limitations. Thus, there is a clear need to identify or develop, and implement, refined methods for assessing existing bridges in order to determine the most cost-effective options and actions to extend their lives, increase their capacities or replace them.

5. 19. Policy networks : the relation between structure and performance

   Författare :Annica Sandström; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Statsvetenskap;

   Sammanfattning : The importance of policy networks and the need to treat networks seriously have long been emphasized within the field of policy science. However, not many attempts have been made to investigate the explanatory power of policy networks using the tools and theoretical concepts provided by social network analysis (SNA). LÄS MER

7. 20. Sustainability Risk Management in Product Development Companies - Motivating Change

   Författare :Jesko Schulte; Sophie Hallstedt; İdil Gaziulusoy; Blekinge Tekniska Högskola; []
