The market for new durable products of modified wood has increased substan- tially during the last few years, especially in Europe. This increased interest depends partly on the restricted use of toxic preservatives due to increased environmental concern, as well as the need for reduced...
This paper uses network analysis of two fields to demonstrate the value of the technique, and to examine how the fields have changed over time and to what extent they overlap. This was of interest for a COST Action (FP1407, ModWoodLife: http://costfp1407.iam.upr.si)
