Integrated survey methodologies for the knowledge, restoration and valorization of modern architecture. The case study of the Archaeological Museum of Siracusa designed by Franco Minissi
No full textThe knowledge of an articulate architectural organism cannot disregard its critical observation: it is important to detect what it generously shows but especially what it jealously hides. This twofold recognition allows making the essential breakthrough for the planning of a conscious restoration project that will so find on it, a solid support on which to unfold and develop. This identification is a multi-faceted process that can today take advantage of digital technologies. These instruments - if properly selected and managed - can facilitate an indepth investigation, stimulating new considerations and inspiring new fields to explore. In this framework, this paper describes the path followed in the study of a modern building: the Regional Archaeological Museum "Paolo Orsi" in Syracuse, designed by Franco Minissi in the '60s and opened to the public almost 30 years later. This work, based on a careful "reading" of the edifice and its environment, made by integrating archival and documentary analysis and different survey methods, aims at suggesting the proper interventions to conserve and enhance the design process developed by the author. It, also, intends to contribute to the definition of a new approach to the museum visitor experiences through multimedia. Conceived as a vital center for research and cultural promotion, the museum, thanks to virtual reality technologies, can today found new capabilities, although keeping its original spirit
Economic feasibility of a solketal production process from glycerol at small industrial scale
No full textIn order to achieve an industrial scale production of solketal from glycerol it is necessary to analyze the technical and economic feasibility of this industrial process. The technical study presented in this paper considers a small-medium plant capable of producing solketal with a plant processing capacity in the range of 4,000 and 20,000 glycerol t/yr. The process is simulated using an excess of acetone (glycerol to acetone molar ratio = 1:6). The total capital investment was estimated between USD 1 million and USD 3 million for plant processing capacities ranging from 4,000 to 20,000 glycerol t/yr, respectively. It is found that even for plants of 4,000 glycerol t/yr, economic indicators such as net present value (NPV) and internal rate of return (IRR) show that the process is economically viable if the sale price of solketal is higher than 2,400 USD/t. With a solketal selling price of 2,250 USD/t, plants with a minimum capacity of 10,000 glycerol t/yr remain profitable. The sensitivity analysis shows that a reduction in the cost of cooling water required to condense the excess of acetone used in this process is much more critical to the profitability of the project than a longer catalyst useful life.Fil: Vannucci, Julian Agustin.

Recovery and Conservation of Old Water Mills in Central Sicily
No full textAbstractEstablished on the analysis of an area dotted by interesting anthropogenic and natural elements, this paper focuses on the recognition of the cultural value of Central Sicily's river landscape. In the territory of Piazza Armerina (Enna) the presence of streams full of water allowed, since the 14th century, a significant production cycle mainly related to the wheat cultivation and grinding. Of the related watermill system, abandoned as any longer functional, today remain little traces, which are, however, important source of cultural identity. This heritage, if rediscovered, conserved and enhanced, may play an essential role in the area's socioeconomic regeneration

Cancer Narratives : autopathographies in Literature : the Italian Case
No full textL’objectif de cette thèse est d’analyser les écritures de personnes atteintes du cancer. La première partie de notre travail se focalise sur la description des caractéristiques des six ouvrages constituant notre corpus. Nous proposons de les nommer « autopathographies », c’est-à-dire de les définir comme des récits rétrospectifs en prose qu'une personne fait de sa propre maladie, dans lesquels il y a identité entre l’expérience de maladie de l’auteur (tel qu’il figure par son nom sur la couverture), celle du narrateur du récit et celle du malade dont on parle. Le rapport qui s’instaure entre la maladie et l’écriture est à la base de la structure interne de la deuxième et de la troisième partie de notre travail. Dans la deuxième partie, nous analysons le lien entre le cancer et l’écriture : nous démontrons le rôle du corps malade comme objet de l'écriture, mais aussi comme cause et source, dans la mesure où l’attention au corps et à son langage façonne les récits. Le langage choisi pour décrire le cancer est l’objet de l’analyse menée dans la troisième partie. En nous basant sur la segmentation faite dans la deuxième partie, nous identifions les métaphores mobilisées par les patients pour décrire la maladie et le parcours de soins. Notre travail démontre l’existence d’une écriture basée sur l’expérience directe de patients qui enrichit le langage pour « dire » le cancer et la représentation de cette maladie. En annexe se trouvent le fruit de nos entretiens inédits avec Giacomo Cardaci, Cristina Piga et Melania Rizzoli, auteurs de trois des autopathographies analysées.The aim of our work is to investigate the narrative of people diagnosed with cancer. The first part of our study focusses on the description of the characteristics of the six works composing our corpus. We define them « autopathographies », meaning « retrospective prose narrative written by a real person concerning his or hers own illness experience »; in these narratives the experience of illness of the author (whose name designates a real person), the one of the narrator and of the one of principal character are identical. The relationship between cancer and writing is the basis of the structure of the second and of the third part of our research. The aim of the second part is to elucidate the link between cancer and writing; we prove that the diseased body is the topic, cause and source of the autopathographies, since the attention accorded to the diseased body models the story. In the third part of my PhD we focus on the language used to describe cancer. The analysis done in the second part is a starting point to identify the metaphors used by the patients to describe cancer and their experience of illness. Our work demonstrates the existence of a narrative based on the patients’ illness experiences and this narrative enriches the language used to “tell” cancer and its representation. Appendices: synopsis of the autopathographies and interviews of Giacomo Cardaci, Cristina Piga and Melania Rizzoli
A bayesian-like approach to derive chemical abundances in type-2 active galactic nuclei based on photoionization models
No full textWe present a new methodology for the analysis of the emission lines of the interstellar medium in the narrow-line regions around type-2 active galactic nuclei. Our aim is to provide a recipe that can be used for large samples of objects in a consistent way using different sets of optical emission lines that takes into the account possible variations from the O/H-N/O relation to use [N II] lines. Our approach consists of a bayesian-like comparison between certain observed emission-line ratios sensitive to total oxygen abundance, nitrogen-to-oxygen ratio, and ionization parameter with the predictions from a large grid of photoionization models calculated under the most usual conditions in this environment. We applied our method to a sample of Seyfert 2 galaxies with optical emission-line fluxes and determinations of their chemical properties from detailed models in the literature. Our results agree within the errors with other results and confirm the high metallicity of the objects of the sample, with N/O values consistent with a large secondary production of N, but with a large dispersion. The obtained ionization parameters for this sample are much larger than those for star-forming object at the same metallicity. © 2019 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical SocietyThis work has been partly funded by the Spanish MINECO project Estallidos 6 AYA2016-79724-C4 and the Junta de Andalucía for grant EXC/2011 FQM-7058.

Chemodynamics of green pea galaxies - I. Outflows and turbulence driving the escape of ionizing photons and chemical enrichment
No full textWe investigate the ionized gas kinematics, physical properties, and chemical abundances of Sloan Digital Sky Survey J142947, a Green Pea galaxy at redshift z∼ 0.17 with strong, double-peak Ly α emission and indirect evidence of Lyman continuum (LyC) leakage. Using high-dispersion spectroscopy, we perform a multicomponent analysis of emission-line profiles. Our model consistently fits all lines as a narrow component with intrinsic velocity dispersion σ ∼ 40 km s-1, and two broader blue-shifted components with σ ∼ 90 and ∼ 250 km s-1. We find electron densities and temperatures, ionization conditions, and direct O/H and N/O abundances for each component. A highly ionized, metal-poor, young and compact starburst dominates narrow emission, showing evidence of hard radiation fields and elevated N/O. The blue-shifted broader components are consistent with highly turbulent, possibly clumpy ionized gas at the base of a strong photoionized outflow, which accounts for ≳50 per cent of the integrated emission-line fluxes. The outflow is dense and metal-enriched compared to the H ii regions, with expansion velocities larger than those obtained from UV interstellar absorption lines under standard assumptions. Some of these metals may be able to escape, with outflows loading factors comparable to those found in high-z galaxies of similar SFR/Area. Our findings depict a two-stage starburst picture; hard radiation fields from young star clusters illuminate a turbulent and clumpy ISM that has been eroded by SNe feedback. Whilst UV data suggest an extended Ly α halo with high average H i column density, LyC photons could only escape from SDSS J142947 through low H i density channels or filaments in the ISM approaching density-bounded conditions, traced by outflowing gas. © 2020 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical SocietyThis study is based on observations made with the William Hersche Telescope operated on the island of La Palma by the Isaac Newton

Pancreatic Neuroendocrine Tumor (Pan-NET) Presented by Abdominal Pain: A Case Report and Literature Review
No full textA pancreatic neuroendocrine tumor (Pan-NET) is a rare neoplasm originating in the neuroendocrine system. Carcinoid syndrome occurs in approximately 19% of patients with functional Pan-NETs, typically when liver metastases occur. In this paper, we describe the case of a patient with a low-grade non-functional Pan-NET, but with a typical clinical presentation of carcinoid syndrome. An 81-year-old male was admitted to our Department of Internal Medicine at Cannizzaro Hospital (Catania, Italy) because of the onset of abdominal pain with nausea, loose stools, and episodic flushing. Firstly, an abdominal contrast-enhanced CT scan showed a small pancreatic hyper-vascular mass; then, a gallium-68 DOTATOC integrated PET/CT revealed an elevated expression of SSTR receptors. Serum chromogranin A and urinary 5-HIAA measurements were negative. We performed an endoscopic ultrasonography (EUS) by a fine-needle biopsy (EUS-FNB), allowing the immunostaining of a small mass (0.8 cm) and the diagnosis of a low-grade (G1) non-functional Pan-NET (NF-Pan-NET). Surgery was waived, while a follow-up strategy was chosen. The early recognition of Pan-NETs, although rare, is necessary to improve the patient’s survival. Although helpful to allow for immunostaining, EUS-FNB needs to be warranted in future studies comparing EUS-FNB to EUS-FNA (fine-needle aspiration), which is, to date, reported as the tool of choice to diagnose Pan-NETs
