Porosity decreased less for Silbond, since, without a catalyst and an active surface, it hardly polymerized. Therefore, if an ethyl

Lichens have also been investigated in terms of their dispersion by air: sampling methods for the quantitative assessment of the presence of airborne propagules in areas of artistic and archeological interest are proposed.
