Synchrotron radiation-based x-ray analysis of bronze artifacts from an Iron Age site in the Judean Hills

Seven bronze bangles from Tell en-Nasbeh, northern Judah, were investigated to understand the phase composition and manufacturing process of the artifacts, and possibly suggest a provenance for their origin. Synchrotron x-ray radiation diffraction (XRD) and fluorescence (XRF) were used in the analysis to avoid any destructive sampling and at the same time penetrate through the surface into the core metal. These techniques enabled us to determine that the bangles were not just tin bronze, but leaded tin bronze. Based on excavation reports, it is unlikely that the metal objects were manufactured locally at Tell en-Nasbeh; rather, preliminary XRD and XRF data point towards the neighboring region of Edom as their origin. Despite their political enmity during the Iron Age II, the data suggest that Judahite social demands for bronze may have fostered a strong economic relationship between these two polities.     

Preliminary Analysis of the Hull of the Roman Ship from Grado, Gorizia, Italy

The hull of the Roman wreck at Grado has been partially preserved under the cargo of amphoras. The right side presents a rare evidence of a section of the waterway. The ship has been assembled by mortise-and-tenon technique following a shell-first conception. All the frames, except one, are of pine while planking is either of pine and elm. Some strakes, of larix , are a repair made by patch-tenons; a wale shows an other kind of repair. Various signs left by the shipwright are on the hull. In the stern area, a box of wooden elements had to protect a 'hydraulic system'.

Early Neolithic obsidians in Sardinia (Western Mediterranean): the Su Carroppu case

All the obsidians from the undisturbed Early Neolithic (Cardial ware phase I) layer of the Su Carroppu rock-shelter (Sardinia island) were studied. Their elemental composition and that of obsidians from the Monte Arci (Sardinia) volcanic complex was determined by ion beam analysis (PIXE). A comparison between the composition of Su Carroppu artefacts, analysed non-destructively, and that of Western Mediterranean analysed in the same conditions shows that the archaeological material belongs to the SA, SB2 and SC Monte Arci-types, to the exclusion of the SB1 type. The typological/technological study of this industry allowed us to reconstruct two chaînes opératoires, for the production of blades (using predominantly SC obsidians) and of flakes (based exclusively on SA and SB2 obsidians), respectively, but on the whole, assemblage blade/bladelet production was performed somewhat preferably with SA and SB2 types. Thus, in the earliest EN culture known on the island, ancient man had, for the making of its obsidian toolkit, a highly adaptive behaviour applied to the reduction of different useful obsidian sources.     

Testing the waters: the limits of consequentialist logic in Australia’s asylum seeker debate

This work takes existing justifications for Australian asylum seeker policy at face value. For the past five years now both major parties have articulated themselves using the rhetoric of consequentialism, arguing that the policies of offshore detention and boat turn backs are all about securing the safety of refugees. This work puts the personal opinions of each member of parliament aside and examines whether these rhetorical justifications are internally consistent. What will become clear is that the utilitarian framework used in this debate does not sit on terra firma. Rather, its foundations lead to conclusions many might find uncomfortable – suggesting that existing theoretical justifications for Australian asylum seeker policy are ultimately implausible.     

Renaissance and ‘Made in Italy’: marketing Italian fashion through history (1949–1952)

Until 1950, Italian fashion did not exist: there were able tailors and creative designers, but they were known only as individuals and not as part of a wider movement that identified with a specific Italian style. Despite the existence of advanced skills, with the potential to realize an Italian fashion in its own right, there was neither a cultural identity to bind them together nor an international legitimization that would allow the new form to compete with the dominant haute couture of Paris. The revival of the Renaissance and its invention as an intangible asset was fundamental in resolving this ‘dual’ absence, and it therefore became a key factor in the international success of Italian fashion. From the 1950s to today – the period of increasing international success of the ‘Made in Italy’ label – in the rhetoric of entrepreneurs, managers and marketing experts, the Renaissance has become almost an integral part of the DNA of Italian fashion, itself at times represented as the direct descendant and legitimate heir of the excellence of Renaissance taste. This is a link, now taken for granted, for which a term has even been coined: the ‘Renaissance effect’. The fundamental argument that supports this so-called Renaissance effect is in fact that of the continuity between the craftsmanship of the Renaissance age and today's fashion houses; a continuity, however, that has been elaborated through ‘manipulations’ of history which are in part simplistic and in part distorted.     

Monitoring the French Panthéon: From Rondelet’s Historical Surveys to the Modern Automatic System

The damage of a historical structure can be today controlled with many sophisticated instruments. Nevertheless, this type of monitoring can give information only over a very short period of time compared with the long life of the building. This approach can be insufficient to reconstruct the whole evolution of the damage, and thus to understand the stress distribution inside the structural elements, particularly in cases for which long-term phenomena (such as viscosity or soil settlements) are present. To reach this more complex aim, an approach of historical monitoring should be applied, both looking at technical historical documents and surveying the traces of history directly on the monument itself. The case of the French Panthéon is presented in this study, showing the usefulness of this approach also for the present stability assessment. The comparison among the plentiful historical documentation (including 18th-century surveys, monitoring, and technical reports), the present surveys of deformations and the “modern” structural monitoring allowed a complete quantitative reconstruction of the main damages evolution from the construction till now, laying the base for a possible future conscious intervention.     

Results of a 60-Year Monitoring System for Santa Maria del Fiore Dome in Florence

This study aims to present the results of the historical and statistical analysis carried out on the monitoring systems that control one of the most studied domes in the world: Santa Maria del Fiore in Florence, Italy. An accurate analysis of the dome crack widths and of its global displacements (horizontal and vertical), both considering the historical data and more recent data, has allowed detection of the static movements developed in the monument over time as well as in context of their relationship to environmental and seismic phenomena. Thanks to the large amount of measured data (from 1955 to 2010), some previous conclusions on the dome damage trend are updated herein. Moreover, in light of the experimental results, some issues on the dome stability—as the principal hypotheses advanced during centuries about the main cause of Brunelleschi’s dome crack pattern—are reconsidered, including the horizontal thrusts due to the dome’s self-weight characterized by Viviani in 1695 and Chiarugi in 1985, the differential settlement of pillars detailed by Cecchini in 1698, Ximenes in 1757 and Borga in 1975 and the influence of temperature variations investigated by Nervi in 1934. The final aim of this study is to show the great utility of modern and historical monitoring in setting up a reliable forecasting model of the monument.
