Passive RFID Strain-Sensor Based on Meander-Line Antennas

2011

The processing of backscattered signals coming from RFID tags is potentially useful to detect the physical state of the tagged object. It is here shown how to design a completely passive UHF RFID sensor for strain monitoring starting from a flexible meander-line dipole whose shape factor and feed section are engineered to achieve the desired sensing resolution and dynamic range. This class of devices is low-cost, promises sub-millimeter resolution and may found interesting applications in the Structural Health Monitoring of damaged structures and vehicles as well as during extreme and adverse events.

Prefazione a Sulaiman Addonia, Il silenzio è la mia lingua madre

2022

Sulaiman Addonia's 2018 novel Silence is My Mother Tongue, uncharacteristically set in a refugee camp, follows the sentimental education of a girl, Saba, in the place that she, her brother, and their friends have learnt to call home. The Preface to the Italian edition remarks how this classic and yet extraordinary coming-of-age novel offers a fundamental counter-narrative to the mainstream representations of life stories of minor refugees all over the world.

Differential roles of cAMP and cGMP in megakaryocyte maturation and platelet biogenesis

2012

The cyclic nucleotides cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) regulate the activity of protein kinase A (PKA) and protein kinase G (PKG), respectively. This process helps maintain circulating platelets in a resting state. Here we studied the role of cAMP and cGMP in the regulation of megakaryocyte (MK) differentiation and platelet formation. Cultured, platelet-producing MKs were differentiated from fetal livers harvested from 13.5 days postcoital mouse embryos. MK development was accompanied by a dramatic increase in cAMP production and expression of soluble guanylate cyclase, PKG, and PKA as well as their downstream targets vasodilator-stimulated ph…

Quantifying carbon dioxide flux from dormant volcanoes with low-temperature fumarolic activity: demonstration from measurements at La Soufrière, Guad…

2013

Quantifying the flux of magma derived CO2 dissipated by fumarolic fields at dormant volcanoes is fundamental to assess their current state of hydrothermal activity and, therefore, the likelihood of a future phreatic/magmatic eruption. There is, in fact, documented evidence that gas fluxes, and CO2 flux in particular, can increase substantially during volcanic unrests and prior to eruption, due to either degassing of new ascending magma or changes in the hydrothermal system physical regime. Quantifying CO2 emissions is relatively straightforward at open-conduit volcanoes with high-temperature gas venting, which release high enough quantities of SO2 remotely measurable with UV spectroscopy an…

• Volcanic CO2 measurements via Tunable Diode Laser Spectrometer

2014

The analysis of volcanic gas datasets offer key information to build/validate geological models relevant to a variety of volcanic processes and behaviours, including eruptions. In the last decades, near-infrared room-temperature diode lasers, though in an experimental phase, are finding applications in volcanic gas studies. Here, we report on the application of the GasFinder 2.0, a commercial tunable diode infrared laser-receiver unit, operating in the 1.3-1.7 μm wavelength range, to measuring CO2 concentrations in volcanic gas emissions. At first, our field tests were conducted in three different campaigns at Campi Flegrei volcano (near Pozzuoli, Southern Italy), and, subsequently, also in…

Architecture and 15 ka to present volcano-tectono-sedimentary evolution of the Neapolitan Yellow Tuff caldera offshore the Campi Flegrei, (Naples, Ea…

2012

The Campi Flegrei area is structurally dominated by the caldera associated with the eruption of the Neapolitan Yellow Tuff (NYT), a 40 km3 DRE ignimbrite dated at ca 15 ka BP [Deino et al., 2004], The volcanological evolution of the NYT caldera as been long described on the basis of outcrop and subsurface studies onland [Rosi & Sbrana, 1987; Orsi et al., 1996, and references therein; Di Vito et al., 1999; Perrotta et al., 2006; Fedele et al., 2011], but its offshore morphology, the stratal geometry of the volcaniclastic products and structures and the late-stage geodynamic evolution of the inner caldera resurgence are still poorly known. We integrate geological and geophysical data obtained…

Desmantling patriarchy: political practices and Spanish feminist movement slogans in the democratic transition

2010

espanolEl movimiento feminista en Espana adquirio su mayor desarrollo en los anos setenta con el inicio de la transicion democratica. El proceso transicional representaba una oportunidad para la reivindicacion de los derechos de las mujeres y poner las nuevas bases sobre el lugar que debian ocupar en la futura sociedad democratica, asi como para denunciar la represion que la dictadura impuso al colectivo femenino. Las campanas y practicas politicas desarrolladas por el movimiento feminista en Espana fueron acompanadas de simbolos y lemas que formaban parte de la produccion simbolica del movimiento feminista como movimiento social. Estas representaciones simbolicas ayudaron configurar una id…

Campsite choice and the camping tourism experience: Investigating decisive campsite attributes using relevance-determinance analysis

2017

Abstract Camping tourism represents a growing part of the overall tourism industry. Despite this fact, this form of tourism has so far been rather neglected by tourism and hospitality research. Using a case study of a major campsite operator in the coastal part of Croatia, this study thus aims to contribute to the understanding of this specific tourist segment. In particular, a relevance-determinance analysis is conducted to reveal most decisive attributes for campsite choice, on the one hand, and for the actual campsite experience, on the other hand. Overall, the results provide valuable insight to practitioners, especially for the purposes of campsite marketing and experience management.

¿Constructores de Mercado y de Estado? A propósito del Campomanes de V. Llombart

1994

This article seeks to discuss some of the conclusions V. Llombart’s study arrives at about the figure and the meaning of the count of Campomanes in the context of absolutism during the second half of the XVIIIth century. More specifically, it calls in question the idea of an action led by a reforming possibilism, half way between the non-enlightenment and the revolution, which would permit, besides, to establish a doubtful line of continuity among some of the reforms of the second half of the century and the plans of Cádiz. It proposes, on the contrary, to reintroduce an interpretative logic not so attached to the schemes of “market” and “state”.
