Abstract

In the present work authors show the results obtained by means of the application of ultra closerange photogrammetry for assessing the pattern of a detached wall painting's surface during/after cleaning treatments. The cleaning treatments are critical operations in conservation so the choice of the method and the definition of the protocol require preliminary activities and studies for the optimization of the procedure. Since the removal of the material is an irreversible operation, an extremely selective method is needed. The criteria traditionally chosen for the selection of the adequate cleaning procedure are the evaluation of the amount of material removed during the treatment and the surface variations (roughness) before and after the treatment. A non-destructive technique could be particularly highlighted as an assessment tool; to this aim the authors propose the photogrammetry method in ultra close-range mode. The ultra close-range photogrammetry is a total non-invasive method, fully portable, and easy to use. The cleaning treatments studied in this work are chemical cleaning, and laser cleaning. The obtained information on the third dimension of the surface by means of ultra close-range photogrammetry was compared with results performed by 3D optical microscope (only on selected single points). The colorimetric information on selected areas during and after the cleaning completes the surviving activity. The performed tests on the case study demonstrate the ability of the proposed approach to control the effectiveness of the cleaning procedures applied on wall paintings during conservation interventions. The advantages due to the portability and to the non-destructivity of photogrammetry (no-contact measurement method) with regard to others techniques candidates, led this methodology to be used in wider restoration works.

Abstract

A trial was conducted to evaluate the growth performance and survival of Chelidonichthys lucerna. A total of 13 352 180-days old juveniles (5.5 ± 2 g; 5 ± 1 cm) were reared at two different densities (A- EXP = 68 fish m−3; B- FFA = 15 fish m−3) in eight tanks (four tanks per group) for 360 days. The welfare status and meat quality of fish were evaluated for the A- EXP and B- FFA groups in comparison with wild-caught fishery gurnard (C- WID). The survival rate was high for both A- EXP (79%) and B- FFA (93.5%). B- FFA fish had the highest specific growth rate (1.16 vs. 1.07; P < 0.05), and were heavier than A- EXP fish (321 ± 40 g vs .239 ± 44 g; P < 0.01). Rearing conditions did not affect blood metabolites, except for glucose concentrations, which were higher in C- WID ( P < 0.05). The meat quality traits showed that reared groups were fatter (2.8-3.2%) than C- WID (0.94%); total n-3 fatty acids (19.02-19.26%) were lower in reared groups than C- WID (29.99%); and EPA + DHA were similar in all groups (15.1-16.61% vs. 27.99%). Despite the good growth and survival, the final mean weight was below that requested by the market (400-500 g). Future research efforts should focus on reducing the feed conversion rate (3:1).
