Roman Women e Public History: la creatività del Web
2018
Partendo dal dibattito sviluppatosi negli USA alla metà degli Anni Settanta sulla condizione femminile nel mondo antico, l’articolo sottolinea che ha contribuito a dare una lettura articolata dell’immagine delle donne romane. Ciò ha inciso non solo sulla storiografia posteriore, bensì oltre, come si ricava da alcuni recenti video YouTube sulle Roman Women, rinvenibili in rete. Essi mostrano la creatività dei loro autori, i loro diversi livelli di conoscenza e capacità tecniche. D’altro lato, proiettano lo spettatore nella vita quotidiana delle donne dell’antica Roma. In tal senso, questo genere di produzione può essere considerato un ottimo esempio di Public History applicata e risultare ef…
Analysis of the 2011 Japan's triple disaster from a conceptual ontology of the domain of risk and disaster,
2012
International audience; In this paper, we propose to use the factual part of a conceptual ontology realized in 2009 (Provitolo and al. 2009 a) to analyze the disaster that occurred in Japan on 11 March 2011 and which was characterized by a sequence of earthquake, tsunami and nuclear accident. Many papers, reports, videos and press articles were published, each one providing a wide variety of information. Some fo- cused on the massive earthquake that triggered the devastating tsunami waves along the eastern coast of the Tohoku region while others mainly analyzed the nuclear crisis. The aim of this work is to syn- thesize in visual form information from various sources and to produce differen…
Acoustic properties of plates with unevenly distributed macro perforations backed by woven meshes
2012
A hybrid model describing the acoustic properties of plates with macro-perforations that can be unevenly distributed on the plate surface and backed by woven or precision woven meshes with microscopic perforations is proposed. The plate perforations may be of circular or rectangular shapes. Since the perforated plate may not necessarily be considered as an equivalent fluid, its surface impedance is calculated by the Maa model [Noise Control Eng. J. 29, 77-84 (1987)], whereas the Johnson-Champoux-Allard model [J. Appl. Phys. 70, 1975-1979 (1991)] is used for the mesh. It is observed that the absorption of the carrying plate seems to depend on the hydraulic diameter of the perforations and no…
Political Action Beyond Resistance: Arendt and "Revolutionary Spirit" in Egypt
2016
The article examines what it calls the "politics-as-resistance" frame in contemporary political theory, originating in the works of Michel Foucault and Judith Butler. This way of organizing political experience is contrasted with Hannah Arendt's political thought, particularly her writings on revolutionary action. Arendt's often overlooked – and partly unpublished – passages on virtù and fortuna are further suggested as important additions to her thinking on action. I argue that Arendt's "world-centric" approach can illuminate certain aspects of political experience that remain dimmed in the more subject-oriented politics-as-resistance frame. Particular focus is paid to the austere notion o…
Coseismic extension recorded within the damage zone of the Vado di Ferruccio Thrust Fault, Central Apennines, Italy
2018
Recent high resolution hypocentral localisation along active fault systems in the Central Apennines illuminates the activation of seismogenic volumes dipping at low angle (<30°) in extensional settings overprinting contractional deformations affecting the continental crust of the Adria microplate. Individuation of the geological structures and of the fault processes associated with these seismic patterns will contribute to the interpretation of seismic sequence evolution, and seismic hazard studies.Here we report field and microstructural evidence of seismogenic extensional faults localized within pre-existing thrust fault zones. The Vado di Ferruccio Thrust Fault (VFTF) is a narrow …
A damage identification procedure based on Hilbert transform: Experimental validation
2010
SUMMARY This paper aims at validating the feasibility of an identification procedure, based on the use of the Hilbert transform, by means of experimental tests for shear-type multi-degree-of-freedom systems. Particularly, a three-degree-of-freedom frame will be studied either numerically or experimentally by means of a laboratory scale model built at the laboratory of the Structural, Aerospace and Geotechnical Engineering Department (DISAG) of University of Palermo. Several damage scenarios have been considered to prove the effectiveness of the procedure. Moreover, the experimental tests have been conducted by considering two different input loads: pulse forces, simulated by means of an ins…
An algorithm for earthquakes clustering based on maximum likelihood
2007
In this paper we propose a clustering technique set up to separate and find out the two main components of seismicity: the background seismicity and the triggered one. We suppose that a seismic catalogue is the realization of a non homogeneous space-time Poisson clustered process, with a different parametrization for the intensity function of the Poisson-type component and of the clustered (triggered) component. The method here proposed assigns each earthquake to the cluster of earthquakes, or to the set of independent events, according to the increment to the likelihood function, computed using the conditional intensity function estimated by maximum likelihood methods and iteratively chang…
Transportan 10 Induces Perturbation and Pores Formation in Giant Plasma Membrane Vesicles Derived from Cancer Liver Cells
2023
Continuous progress has been made in the development of new molecules for therapeutic purposes. This is driven by the need to address several challenges such as molecular instability and biocompatibility, difficulties in crossing the plasma membrane, and the development of host resistance. In this context, cell-penetrating peptides (CPPs) constitute a promising tool for the development of new therapies due to their intrinsic ability to deliver therapeutic molecules to cells and tissues. These short peptides have gained increasing attention for applications in drug delivery as well as for their antimicrobial and anticancer activity but the general rules regulating the events involved in cell…
L'abitare in pratica. Esperimenti nel post-sisma di Configno e Capricchia
2021
The seismic sequence that struck central Italy in 2016-2017 triggered intense de- and reterritorialization processes. This paper examines the cases of Capricchia and Configno (Amatrice, RI) where, with the active participation of non-residents owners of second homes, the communities have undergone autonomous processes in order to not abandon the place of residence while waiting for the institutional emergency solutions. Based on the perspective of social geography, this paper intends to analyze the bottom-up reterritorialization processes and open the discussion on the value and legitimacy of intervention of non-resident subjects.
