No full textTerracotta Imitation of Jewelry. Iconography and function
No full textBetween the end of the 4th and the beginning of the 3rd century B.C., the practice of reproducing jewellery and other objects used as personal ornament in the medium of gilded clay spread throughout the Greek world. The close comparisons drawn between such objects and prestigious artifacts of jewellery have led scholars to assign the former the function of "clay imitations of gold jewellery”, i.e. as reproductions of high quality items produced out of far "poorer" material with the intent to meet a wider demand. However, the data culled from the numerous ancient cemeteries discovered in northern Greece, Bulgarian Thrace, and Magna Graecia (Taras), as well as in many other sites that have yielded these products, offer a new interpretation.
The most significant results to emerge from the research can be summarized as follows:
1) For each of the aforementioned areas the records point to an overall scarcity of such products with respect to the other categories of clay artifacts and gold jewellery of similar date recovered in the same areas. This data is incongruent with any notion of mass production that the low cost would presumably have encouraged.
2) These gilded clay objects are chiefly found in funerary contexts, in either the most elite of monuments such as the tombs in Derveni and the Mound Tjulbe in the valley of Kazanluk (Bulgary) or more modest tombs, which stand out nonetheless for their sheer number and variety of materials together with the highly refined taste that choice items among their burial goods reflect. The latter tombs frequently boast valuables made out of gold, silver, ivory and alabaster that reveal the owners’ belonging to an emerging social class while confirming the luxury status to be assigned to these objects.
3) Though in some geographical areas the gilded terracotta objects are associated with the funerary rite of cremation, still others appear inside inhumation burials. The placement of these items in the tombs indicates, however, that their use is strictly connected to the funeral ritual and to be distinguished from the rest of the burial goods.
4) The use of these objects likely originated from a fad born in Macedonia, where a particular category of gilded pottery, serving analogous funerary purposes, was in vogue during the same period. This datum suggests that this region assigned a high value to the practice of gilding, whose open display together with that of other precious materials had become a status symbol
Mediterranean Connections beyond the Mediterranean : Classical and Early Hellenistic Decorative Systems in Thrace and in the Northern Black Sea Region
No full textIl contributo considera documenti pittorici della Tracia e del Mar Nero settentrionale, databili tra IV e III sec. a.C. seguendo un approccio contestuale e attingendo a fonti di archivio. L’analisi riguarda sia i criteri di articolazione della parete che i motivi inseriti nella parete. L’obiettivo è esplorare le “connessioni” mediterranee di tali prodotti artistici come risultato di mobilità di persone, idee e saperi e come indizio di relazioni interculturali tra popolazioni di diversa origine.Using a contextual approach and drawing on archival sources, this article examines pictorial documents from Thrace and the northern Black Sea, dating to the 4th and 3rd centuries BCE. The analysis focuses on both the structural organization of the walls and the motifs incorporated within them. The aim is to explore the Mediterranean 'connections' of these artistic products, resulting from the mobility of people, ideas, and knowledge, and as evidence of intercultural interactions between populations of diverse origin

Updating the water budget of the Gran Sasso carbonate fractured/karstified aquifer (Central Italy) for a sustainable management of groundwater resources
No full textKarst aquifers are fundamental in the water supply of European countries, where outcrops of carbonate rocks are very common, providing abundant groundwater resources. The Gran Sasso karst aquifer, selected as representative study area for Italy in the EU-funded KARMA project, is characterized by both high percentage of withdrawals for drinking purposes and significant interaction between groundwater and underground works. The recharge evaluation of the aquifer has been carried out considering the 2001–2020 monitoring period, comparing three different methods: the Turc and APLIS methods, on annual scale, and the Thornthwaite method, on monthly scale, territorially distributed by 100 x 100 m cells on GIS basis. The total recharge considers not only rainfall but also the contribution of snow melting on infiltration. The results show similar mean recharge values in 2001–2020 for all methods, corresponding to 19.9, 18.5, and 19.4 m3/s, respectively, from Turc, Thornthwaite, and APLIS methods. A significant contribution to recharge from snowmelt has been confirmed (3.2 m3/s included in the above-mentioned values). These values can be considered reliable with respect to real discharge of the regional aquifer. The obtained results can be used to provide updated information to the drinking water companies for a suitable management of the available resource
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Modulation of Light and Nitrogen for Quality-Traits Improvement: A Case Study of Altino Sweet Pepper
No full textLocal varieties are known to cope more efficiently with stressful and/or low-input conditions than cultivated ones by activating secondary metabolisms and, hence, are supposed to have higher nutraceutical potential. In this work, we investigate the effects of N and light, supplied at optimal and sub-optimal levels, on the fruit yield and quality of a local ecotype of sweet pepper, Altino, grown in the Abruzzo Region (Southern Italy). In 2017, two open-field experiments were carried out, comparing increasing N rates (0, 100 and 200 kg N ha(-1), 0_N, 100_N and 200_N, respectively) and different percentages of shading and/or manipulations of the transmitted solar radiation, obtained through photoselective nets (red net, RN; black net, BN; unshaded Control). Both N and light were preconditions to obtain stable yields in terms of both fruit number and fruit weights. However, BN significantly reduced the number of sunscalded fruits (0.39 vs. 3.38 and 2.59 fruit plant(-1) for BN, Control and RN, respectively), leading to lower waste. N deficiency favoured higher total polyphenol (TPC) and flavonoid (TFC) contents in ripened fruits; on the other hand, shading significantly reduced TPC (-12.4%) in immature and TFC (-18.2%) in red fruits. The variations in nutraceuticals were also evaluated in terms of the variations of the single phenolic acids in fruits during ripening; the most interesting results were associated with light treatments. Further research should be directed to the in-depth study of nutrition regimes, in combination with other photoselective nets applications (i.e., pearl nets), that could be suitable for the Altino genotype to enhance the yield and nutraceutical potentials of its fruits

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
