CAD-CAE methods to support restoration and museum exhibition of bronze statues: the “Principe Ellenistico”

Ancient bronze statues mainly require material integrity assessment and restoration. Restoration may include also the update of the museum exhibition, defining new structural frames and fragment re-composition to preserve the statue and improve the interpretation of the original aspect. This paper proves how engineering methods (such as Finite Element Analysis, Computer Aided Design modelling, Reverse Engineering) may assist cultural heritage experts and restorers in these tasks. It presents the activities made together with the Museo Nazionale Romano and the Istituto Superiore per la Conservazione e il Restauro, on the so-called “Principe Ellenistico” (Hellenistic Prince). This bronze was found in pieces (body, left arm and right leg), at the end of 19th century during an excavation made in Rome. No visual or reference sources can say its origin and its final posture was defined by restorers at the end of the 19th century according to their hypothesis and studies. In the 20th century, a further restoration was made on the critical areas of the surface, together with some structural improvement of the inner frame. Nowadays, after a review of its position inside the Museum, new experimental and numerical analyses have been carried out to better understand surface weakness and correct left arm positionin

Jung and ethics: A conceptual exploration

Despite Jung’s frequent claims that one’s moral and ethical stance play an important role both in the development and in the cure of neurosis, Jung’s ethical position had not been subjected to a critical assessment and the main sources of his ethical outlook had not been investigated. I take my point of departure in Jung’s definition of ethics as involving both consciousness and the unconscious. In the first chapter, Kant’s argument for the primacy of practical reason is shown to ground Jung’s conviction of the decisive freedom of the ego. Jung’s insistence on the importance of the moral development of both patient and therapist is also related to Kant’s call for moral independence. Having elucidated Jung’s understanding of conflicts of duty – the existence of which was denied by Kant – I discuss Jung’s Nietzschean legacy. I argue that Jung derives the crucial distinction between ethics and morality from Nietzsche, as well as the idea that ethics must consider the irrational and unintentional side of the Self; I also consider how Jung’s application of the ‘health criterion’ to ethics differs from Nietzsche’s utilisation of the same device. In Chapter 3, I highlight the critical convergence between Aristotle’s approach to ethics and Jung’s psycho-ethical paradigm: while both stress the importance of acquiring a balance between reason and the passions and place wisdom at centre stage, Jung adds that psychotherapy can successfully integrate ‘unconscious vice’. In the fourth chapter, I examine the (heterodox) Christian side of Jung’s ethics. Here I assess the role played by the psychologically ‘heavy’ notion of evil in Jung’s model and analyse the often-misunderstood link between evil and the Shadow. In Jung’s psychology, the individuated subject is the ethical subject, so depth psychology and ethics converge towards the same goal and can be mutually supportive endeavours

I nostri figli, le nostre scuole, il nostro futuro: la scuola del futuro parte dall’Aquila

Policy paper La scuola è luogo di cittadinanza, soprattutto in una città che ha bisogno di cittadini “nuovi”, consapevoli del passato e portatori di futuro. Le nuove generazioni hanno il diritto di formarsi in spazi sicuri e ben organizzati, che consentano lo sviluppo dei migliori processi di apprendimento ed insegnamento, di partecipazione, di socializzazione e di acquisizione di sensibilità, valori da spendere positivamente nella costruzione della città futura

Disentangling the intrinsic relaxivities of highly purified graphene oxide

The chemistry of Contrast Agents (CAs) for Magnetic Resonance Imaging (MRI) applications is an active area of research and, in recent work, it was shown that CA-based Graphene Oxide (GO) has valuable properties for biomedical uses. GO has a potential as MRI CAs thanks to several functionalities, like its ability to penetrate tissues and cell membranes, as well as easy coupling with therapeutic agents, therefore showing the potential for both a diagnostic and therapeutic role. In this study, we performed a thorough cleaning of the GO sample (synthesized using a modified Hummers method), minimizing the amount of residual manganese down to 73 ppm. Using a wide range of physical-chemical methods (morphology, chemical composition, elemental analysis, spectroscopies, and imaging), we characterized the intrinsic longitudinal and transverse relaxivities of highly purified GO nanosheets. X-band Electron Paramagnetic Resonance (EPR) allowed to recognize the paramagnetic species involved, and 1.0 T MRI was used to disentangle the relative contributions to the MRI contrast of pristine GO nanosheets arising from structural defects and residual paramagnetic manganese impurities embedded in the nanomaterial. Although experiments show that the MRI relaxivity of GO nanosheets arises from the cumulative effect of structural defects and paramagnetic impurities, we conclude that the latter contribution to the longitudinal and transverse relaxivities becomes irrelevant for highly purified (pristine) GO. This novel finding clearly demonstrate that, apart from trivial manganese inclusion, pristine GO produces an inherent MRI response via structural defects, and therefore it is on its own a suitable candidate as MRI contrast agent
