2008
The poor outcome of numerous restorations on artefacts of historical and artistic interest, after a few years, has shown how indispensable an accurate preliminary assessment of the conservation problems of the artefact is for the purposes of the reliability of the intervention. The correct diagnosis of the causes upstream of the phenomena of alteration and degradation, whether physiological or pathological, becomes the fundamental prerequisite for choosing any conservative or restorative intervention. From this point of view, in order to provide the reader with a useful tool for investigation and recognition in the field, the text illustrates the phenomena of alteration and degradation that…

When solving decision problems where multiple conflicting criteria are to be considered simultaneously, decision makers must compare several different alternatives and select the most preferred one.

COVID-19 could also be spread when patients touches a contaminated surface with infected droplets and then touch their nose, mouth, or eyes. It is time to consider a dental practice quite similar to a hospital surgery room, where particular attention should be addressed to problems related to the spreading of infections due to air and surface contamination. The effectiveness of conventional cleaning and disinfection procedures may be limited by seve…
