Il tempo nuovo dei beni culturali, dell'economia e dei territori

2021

The essay examines the evolution of the relationship between culture and economy in the legal debate, in the perspective of the progressive overcoming of the opposing tendencies to the mixture between the two areas in relation to the growing dimension of the enhancement of cultural heritage, identifying the weaknesses of the discipline (regional ) the participation of cultural assets in the urban regeneration of territories

PATRIMONIO CULTURALE E MARGINALITÀ. LA PANDEMIA DELLA SOLITUDINE. QUALE RIGENERAZIONE?

2021

We start from the assumption that culture is what man assimilates, modifies and transforms, to which he contributes with his work, adding to and preserving the historical heritage. The sum of heritage diversities and values gives cultural uniqueness to the coexistence of the communities that make up each territory. Our main task, the task of each one of us who with an educated eye understands the meaning and value of heritage, must be directed towards committing ourselves not only to be actors in the present historical moment in which such testimonies survive, but to be authors of practices of preservation and enhancement. We cannot learn culture just by looking at its symbols, but by livin…

Piccole città per quarantenni. Sul senso di sé nella scrittura storiografica, in margine a un libro di Vanessa Roghi

2019

Starting from an analysis of Vanessa Roghi's recent book, Piccole città, we focus on the link between historiographic writing and autobiography. In particular, it analyzes the way this link changed at the end of the twentieth century, when political categories that had determined identities, even of historians, for more than a century, have finished. Since then, issues considered "private" have emerged in the public debate and in the historiographic debate, as happened for example with drug addiction, at the centre of Roghi's book.

Fabrication of quercetin and curcumin bionanovesicles for the prevention and rapid regeneration of full-thickness skin defects on mice

2013

In the present work biocompatible quercetin and curcumin nanovesicles were developed as a novel approach to prevent and restore skin tissue defects on chronic cutaneous pathologies. Stable and suitable quercetin- and curcumin-loaded phospholipid vesicles, namely liposomes and penetration enhancer-containing vesicles (PEVs), were prepared. Vesicles were made from a highly biocompatible mixture of phospholipids and alternatively a natural polyphenol, quercetin or curcumin. Liposomes were obtained by adding water, while PEVs by adding polyethylene glycol 400 and Oramix®CG110 to the water phase. Transmission electron microscopy, cryogenic-transmission electron microscopy and small- and wide-ang…

Deciliation: A stressful event for Paracentrotus lividus embryos.

1998

In this report, by using mono- and two-dimensional electrophoretic analysis, we demonstrate that deciliation on sea urchin embryos induces a stress response. Deciliation indeed causes not only the activation of ciliary subroutine, but also a transient decrease of bulk protein synthesis. This decrease is in agreement with our previous results on heat shock response in sea urchin, although deciliation does not induce the expression of the same main hsp set. We were able to characterize one main deciliation-stress protein of 40 kDa whose expression is transiently induced by deciliation and whose localisation is likely to be nuclear.

Robots that look like humans: A brief look into humanoid robotics

2018

This article provides a brief overview of the technology of humanoid robots. First, historical development and hardware progress are presented mainly on human-size full-body biped humanoid robots, together with progress in pattern generation of biped locomotion. Then, «whole-body motion» – coordinating leg and arm movements to fully leverage humanoids’ high degrees of freedom – is presented, followed by its applications in fields such as device evaluation and large-scale assembly. Upper-body humanoids with a mobile base, which are mainly utilized for research on human-robot interaction and cognitive robotics, are also introduced before addressing current issues and perspectives.

Recovery of endogenous beta cell function in non-human primates following chemical diabetes induction and islet transplantation

2009

Objectives: To describe the ability of non-human primate endocrine pancreata to re-establish endogenous insulin production after chemical beta cell destruction. Research Design and Methods: Eleven monkeys (macaca fascicularis) were rendered diabetic with streptozotocin. Eight diabetic monkeys received intraportal porcine islet transplantation. Results: Two monkeys transplanted after 75 days of insulin dependent diabetes, showed recovery of endogenous C-peptide production a few weeks after transplantation, concomitant with graft failure. Histological analysis of the pancreas of these monkeys showed insulin-positive cells, single or in small aggregates scattered in the pancreas and adjacent t…

Slow-roll corrections in multi-field inflation: a separate universes approach

2018

In view of cosmological parameters being measured to ever higher precision, theoretical predictions must also be computed to an equally high level of precision. In this work we investigate the impact on such predictions of relaxing some of the simplifying assumptions often used in these computations. In particular, we investigate the importance of slow-roll corrections in the computation of multi-field inflation observables, such as the amplitude of the scalar spectrum $P_\zeta$, its spectral tilt $n_s$, the tensor-to-scalar ratio $r$ and the non-Gaussianity parameter $f_{NL}$. To this end we use the separate universes approach and $\delta N$ formalism, which allows us to consider slow-roll…

The 2020 skyrmionics roadmap

2020

The notion of non-trivial topological winding in condensed matter systems represents a major area of present-day theoretical and experimental research. Magnetic materials offer a versatile platform that is particularly amenable for the exploration of topological spin solitons in real space such as skyrmions. First identified in non-centrosymmetric bulk materials, the rapidly growing zoology of materials systems hosting skyrmions and related topological spin solitons includes bulk compounds, surfaces, thin films, heterostructures, nano-wires and nano-dots. This underscores an exceptional potential for major breakthroughs ranging from fundamental questions to applications as driven by an inte…
