Atmospheric corrosion of quaternary bronzes (Cu-Sn-Zn-Pb): laboratory tests (accelerated ageing in wet & dry conditions)and field studies (the Bottego monument in Parma, Italy).

The interactions between outdoor bronzes and the environment, which lead to bronze corrosion, require a better understanding in order to design effective conservation strategies in the Cultural Heritage field. In the present work, investigations on real patinas of the outdoor monument to Vittorio Bottego (Parma, Italy) and laboratory studies on accelerated corrosion testing of inhibited (by silane-based films, with and without ceria nanoparticles) and non-inhibited quaternary bronzes are reported and discussed. In particular, a wet&dry ageing method was used both for testing the efficiency of the inhibitor and for patinating bronze coupons before applying the inhibitor. A wide range of spectroscopic techniques has been used, for characterizing the core metal (SEM+EDS, XRF, AAS), the corroded surfaces (SEM+EDS, portable XRF, micro-Raman, ATR-IR, Py-GC-MS) and the ageing solutions (AAS). The main conclusions were: 1. The investigations on the Bottego monument confirmed the differentiation of the corrosion products as a function of the exposure geometry, already observed in previous works, further highlighting the need to take into account the different surface features when selecting conservation procedures such as the application of inhibitors (i.e. the relative Sn enrichment in unsheltered areas requires inhibitors which effectively interact not only with Cu but also with Sn). 2. The ageing (pre-patination) cycle on coupons was able to reproduce the relative Sn enrichment that actually happens in real patinated surfaces, making the bronze specimens representative of the real support for bronze inhibitors. 3. The non-toxic silane-based inhibitors display a good protective efficiency towards pre-patinated surfaces, differently from other widely used inhibitors such as benzotriazole (BTA) and its derivatives. 4. The 3-mercapto-propyl-trimethoxy-silane (PropS-SH) additivated with CeO2 nanoparticles generally offered a better corrosion protection than PropS-SH.

Urban water demand model: the case study of Emilia Romagna (Italy)

Water is the driving force in nature. We use water for washing cars, doing laundry, cooking, taking a shower, but also to generate energy and electricity. Therefore water is a necessary product in our daily lives (USGS. Howard Perlman, 2013). The model that we created is based on the urban water demand computer model from the Pacific Institute (California). With this model we will forecast the future urban water use of Emilia Romagna up to the year of 2030. We will analyze the urban water demand in Emilia Romagna that includes the 9 provinces: Bologna, Ferrara, Forli-Cesena, Modena, Parma, Piacenza, Ravenna, Reggio Emilia and Rimini. The term urban water refers to the water used in cities and suburbs and in homes in the rural areas. This will include the residential, commercial, institutional and the industrial use. In this research, we will cover the water saving technologies that can help to save water for daily use. We will project what influence these technologies have to the urban water demand, and what it can mean for future urban water demands. The ongoing climate change can reduce the snowpack, and extreme floods or droughts in Italy. The changing climate and development patterns are expected to have a significant impact on water demand in the future. We will do this by conducting different scenario analyses, by combining different population projections, climate influence and water saving technologies. In addition, we will also conduct a sensitivity analyses. The several analyses will show us how future urban water demand is likely respond to changes in water conservation technologies, population, climate, water price and consumption. I hope the research can contribute to the insight of the reader’s thoughts and opinion.

Seismic vulnerability of the ancient albergotti's manor in Arezzo, Italy

The thesis moves from the need of understanding how a historical building would behave in case of earthquake and this purpose is strongly linked to the fact that the majority of Italian structures are old ones placed in seismic sites. Primarily an architectural and chronological research is provided in order to figure out how the building has developed in time; then, after the reconstruction of the skeleton of the analyzed element (“Villa i Bossi” in Gragnone, AR), a virtual model is created such that the main walls and sections are tested according to the magnitude of expected seismic events within the reference area. This approach is basically aimed at verifying the structure’s reliability as composed by single units; the latter are treated individually in order to find out all the main critical points where rehabilitation might be needed. Finally the most harmful sections are studied in detail and proper strengthening is advised according to the current know-how.

L'ethos del marchio "Barilla" nella comunicazione pubblicitaria francese: Un modello di valorizzazione del made in Italy.

L’elaborato propone un’analisi dettagliata della configurazione del discorso pubblicitario, inteso come il risultato di una duplice operazione: quella di produzione del messaggio, a opera del pubblicitario, utente di precise strategie discorsive, e quella di interpretazione, da parte del destinatario che completa il significato dell’enunciato attribuendogli le proprie peculiari connotazioni. Il corpus utilizzato consiste in una raccolta di spot pubblicitari prodotti dall’azienda Barilla per i telespettatori francofoni, ed è stato reperito presso l’Archivio Storico di Barilla nella sede di Parma. L’illustrazione e la descrizione di alcune pubblicità scelte come modelli forniscono la base per l’approfondimento di alcune problematiche linguistiche e traduttologiche; in particolare, viene posto l’accento sulla nozione di ethos discorsivo, collocabile nell'ambito dell’analisi del discorso, e su quella di stereotipo linguistico, considerato come veicolo culturale e strumento dotato di straordinaria forza assertiva e pertanto prediletto dalla comunicazione pubblicitaria. Tale forma di linguaggio merita di essere analizzata e studiata nella sua ricca complessità, dal momento che è da considerarsi come il più efficace e moderno mezzo di diffusione, incorporazione e assimilazione di valori e comportamenti culturalmente orientati.

Relazioni fra regime dei venti e pH in un "campo di fumarole" a CO2 sui fondali costieri dell'isola d'Ischia (Italy).

Il problema dell'acidificazione degli oceani, conseguente ai cambiamenti climatici, è un processo ancora poco conosciuto. Per comprendere questo fenomeno, possono essere utilizzati degli ambienti naturalmente acidificati, considerati laboratori a cielo aperto. Lo scopo di questo lavoro di tesi è stato quello di utilizzare le fumarole presenti nell'isola di Ischia, per approfondire le dinamiche dei processi di acidificazione e per analizzare l'eventuale interazione tra pH e condizioni meteorologiche. I dati utilizzati, forniti dalla Stazione Zoologica “Anton Dohrn” di Napoli, erano serie di pH e di vento rilevate in continuo, in due aree, nord e sud rispetto all'isolotto del Castello Aragonese, e in tre stazioni lungo un gradiente di acidificazione. Tutto il lavoro è stato svolto a step, dove il risultato di un'analisi suggeriva il tipo e il metodo analitico da utilizzare nelle analisi successive. Inizialmente i dati delle due serie sono stati analizzati singolarmente per ottenere i parametri più salienti delle due serie. In seguito i dati sono stati correlati fra loro per stimare l'influenza del vento sul pH. Globalmente è stato possibile evidenziare come il fenomeno dell'acidificazione sia correlato con il vento, ma la risposta sembra essere sito-specifica, essendo risultato dipendente da altri fattori interagenti a scala locale, come la geomorfologia del territorio, le correnti marine e la batimetria del fondale. È però emersa anche la difficoltà nel trovare chiare correlazioni fra le due serie indagate, perché molto complesse, a causa sia della numerosa quantità di zeri nella serie del vento, sia da una forte variabilità naturale del pH, nelle varie stazioni esaminate. In generale, con questo lavoro si è dimostrato come utilizzare tecniche di analisi delle serie storiche, e come poter utilizzare metodi di regressione, autocorrelazione, cross-correlation e smoothing che possono integrare i modelli che prendono in considerazione variabili esogene rispetto alla variabile di interesse.

Proposta di sottotitolaggio del social movie italy in a day

The aim of this thesis is to analyse the main translating issues related to the subtitling of the Italian social movie Italy in a day into English: Italy in a day is a crowdsourced film, comprising a selection of video clips sent by ordinary people, showing occurrences of everyday life on a single day, October 26th, 2013. My dissertation consists of four chapters. The first provides a general overview of audiovisual translation, from the description of the characteristics of filmic products to a summary of the most important audiovisual translation modes; a theoretical framework of the discipline is also provided, through the analysis of the major contributions of Translations Studies and the multidisciplinary approach proposed by the scholar Frederic Chaume. The second chapter offers insight into the subtitling practice, examining its technical parameters, the spatial and temporal constraints, together with the advantages and pitfalls of this translation mode. The main criteria for quality assessment are also outlined, as well as the procedures carried out in the creation of subtitles within a professional environment, with a particular focus on the production of subtitles for the DVD industry. In the third chapter a definition of social movie is provided and the audiovisual material is accurately described, both in form and content. The creation of the subtitling project is here illustrated: after giving some information about the software employed, every step of the process is explained. In the final chapter the main translation challenges are highlighted. In the first part some text reduction techniques in the shift from oral to written are presented; then the culture-specific references and the linguistic variation in the film are analysed and the compensating strategies adopted to fill the linguistic and cultural gap are commented on and justified taking into account the needs and expectations of the target audience.

Distribution of metals in several vineyards of North Italy: from soil to wine

Nowadays we live in densely populated regions and this leads to many environmental issues. Among all pollutants that human activities originate, metals are relevant because they can be potentially toxic for most of living beings. We studied the fate of Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn in a vineyard environment analysing samples of plant, wine and soil. Sites were chosen considering the type of wine produced, the type of cultivation (both organic and conventional agriculture) and the geographic location. We took vineyards that cultivate the same grape variety, the Trebbiano). We investigated 5 vineyards located in the Ravenna district (Italy): two on the Lamone Valley slopes, one in the area of river-bank deposits near Ravenna city, then a farm near Lugo and one near Bagnacavallo in interfluve regions. We carried out a very detailed characterization of soils in the sites, including the analysis of: pH, electric conductivity, texture, total carbonate and extimated content of dolomite, active carbonate, iron from ammonium oxalate, Iron Deficiency Chlorosis Index (IDCI), total nitrogen and organic carbon, available phosphorous, available potassium and Cation Exchange Capacity (CEC). Then we made the analysis of the bulk chemical composition and a DTPA extraction to determine the available fraction of elements in soils. All the sites have proper ground to cultivate, with already a good amount of nutrients, such as not needing strong fertilisations, but a vineyard on hills suffers from iron deficiency chlorosis due to the high level of active carbonate. We found some soils with much silica and little calcium oxide that confirm the marly sandstone substratum, while other soils have more calcium oxide and more aluminium oxide that confirm the argillaceous marlstone substratum. We found some critical situations, such as high concentrations of Chromium, especially in the farm near Lugo, and we noticed differences between organic vineyards and conventional ones: the conventional ones have a higher enrichment in soils of some metals (Copper and Zinc). Each metal accumulates differently in every single part of grapevines. We found differences between hill plants and lowland ones: behaviors of plants in metal accumulations seems to have patterns. Metals are more abundant in barks, then in leaves or sometimes in roots. Plants seem trying to remove excesses of metal storing them in bark. Two wines have excess of acetic acid and one conventional farm produces wine with content of Zinc over the Italian law limit. We already found evidence of high values relating them with uncontaminated environments, but more investigations are suggested to link those values to their anthropogenic supplies.

Impact of irrigation in the Po valley (Italy) on meteorological parameters through numerical simulation

Recent studies found that soil-atmosphere coupling features, through soil moisture, have been crucial to simulate well heat waves amplitude, duration and intensity. Moreover, it was found that soil moisture depletion both in Winter and Spring anticipates strong heat waves during the Summer. Irrigation in geophysical studies can be intended as an anthropogenic forcing to the soil-moisture, besides changes in land proprieties. In this study, the irrigation was add to a LAM hydrostatic model (BOLAM) and coupled with the soil. The response of the model to irrigation perturbation is analyzed during a dry Summer season. To identify a dry Summer, with overall positive temperature anomalies, an extensive climatological characterization of 2015 was done. The method included a statistical validation on the reference period distribution used to calculate the anomalies. Drought conditions were observed during Summer 2015 and previous seasons, both on the analyzed region and the Alps. Moreover July was characterized as an extreme event for the referred distribution. The numerical simulation consisted on the summer season of 2015 and two run: a control run (CTR), with the soil coupling and a perturbed run (IPR). The perturbation consists on a mask of land use created from the Cropland FAO dataset, where an irrigation water flux of 3 mm/day was applied from 6 A.M. to 9 A.M. every day. The results show that differences between CTR and IPR has a strong daily cycle. The main modifications are on the air masses proprieties, not on to the dynamics. However, changes in the circulation at the boundaries of the Po Valley are observed, and a diagnostic spatial correlation of variable differences shows that soil moisture perturbation explains well the variation observed in the 2 meters height temperature and in the latent heat fluxes.On the other hand, does not explain the spatial shift up and downslope observed during different periods of the day. Given the results, irrigation process affects the atmospheric proprieties on a larger scale than the irrigation, therefore it is important in daily forecast, particularly during hot and dry periods.
