Cover There are many other applications beside the use of polyurethane in medicine like coatings for ships or glass buildings. De illustration shows the hydrodynamic conditions of the environment of adhered bacteria. Omslag Naast het veelvuldig gebruik van polyurethaan in de geneeskunde, heeft polyurethaan andere toepassingen zoals een coating op schepen of glazen gebouwen. De foto illustreert de hydrodynamische condities in een milieu waar gehechte bacteriën voorkomen. Copyright 2004 by D.P.
