Dendrochronological analysis was carried out for 13 historic icons from the collection of the Museum of the Folk Building in Sanok, painted on fir and spruce boards. Eleven sequences of the annual growth rings produced from the analysed fir boards were absolutely dated against the fir dendrochronological standard for S Poland, constructed by E.

The potential utility of laser-induced breakdown spectroscopy (LIBS) as a means to detect biological contaminants on painted surfaces is investigated. Issues involving the use of LIBS for detection of biologicals are discussed. The apparatus assembled for this work is described, as is the manner in which samples of bare copper and painted substrates onto which thin layers of bacterial spores, p...

This part describes the results obtained in the simulations and experiments reported in the previous sessions of this report. A) Statistical comparison of the principal component analysis in various spaces The cumulative contributions of the eigenvectors in each space are summarized for multiple-of-three numbers of eigenvectors in Tables I to III. Table I. Cumulative contribution of the eigenve...

Made by Byzantine painters for Catholic patrons, the fresco cycle of St. Catherine Alexandria in Darlos stands apart from other late-medieval cycles. In terms patronage, style, and iconography, this pictorial raises questions cultural exchange between Byzantium West, illustrating how female holiness was differently articulated these areas.
