Dalla costruzione alla verità dello spazio
2020
Nel progetto di architettura si compie la riconciliazione tra realtà fisica e luogo, ovvero tra un contesto stratificato e molteplice ed un sistema ordinato e dotato di senso che ne esplicita una particolare declinazione estetica. Il progetto è lo strumento capace di governare il dualismo visibile/invisibile da cui scaturisce il movimento che procede dalla materialità della costruzione all’immaterialità dello spazio: la composizione dell’architettura, lungi dal pretendere di cristallizzare tale dinamica in forma, ne deve ricercare la rappresentazione più autentica. Ivi la tragedia della finitezza della forma e la speranza senza fine della vita si contrappongono e contemporaneamente si autor…
NANO, SMART AND COMPOSITE MATERIALS IN CONSTRUCTION
2018
Si può generalmente affermare che l’industria delle costruzioni costituisca un settore capace di attivare grandi attività economiche e di spe- rimentazione, anche se spesso esso utilizzi componenti e sistemi abbastanza obsoleti, se paragonati ad altri settori industriali quali, ad esempio, quello bellico o farmaceutico. La ricerca e lo sviluppo di materiali innovativi costituiscono una priorità delle agende scientifiche di parecchie Nazioni, con investimenti - sia nel pubblico che nel privato - di diversi milioni di dollari l’anno. La scelta tra i nuovi materiali avanzati è sempre più vasta ed articolata, con una capillare attenzione rivolta sia alle prime fasi della progetta- zione che all…
NANOTECHNOLOGY IN CONSTRUCTION: JUST FASHION OR REAL POTENTIALITIES?
2017
Developments of technology and advances in materials science and engineering are leading to a new generation of products that may represent a competitive route to achieve a real sustainable growth in construction. Currently many nano-based products are available on the global market: smart-materials, nano- composite materials, nano-devices, etc.. Further nanotechnologies enable new developments: materials and products are fast emerging or exist in bulky and expensive forms in other industrial sectors. Anyway, a great deal of research, directly focused in construction’s applications, should be done. This paper is aimed to discuss such an increasing trend and analyses the global market. A gen…
Cap Rate as the Interpretative Variable of the Urban Real Estate Capital Asset: A Comparison of Different Sub‐Market Definitions in Palermo, Italy
2017
Real estate capital is in constant competition with other capital assets due to its different and complementary economic functions such as direct use, productive investment, and speculative investment. These features and the resulting opportunities cannot be easily deduced from direct observation of the real estate markets, so some further insights need to be carried out in order to highlight the relationship between prices, rents and performances. This study aims at providing a multifaceted perspective of a specific urban real estate market to overcome the difficulties arising from opacities and informative asymmetries that hinder the decision of investors, by facilitating the comparison o…
Measurements of transition probabilities for two N I infrared transitions and their application for diagnostics of low temperature plasmas
2010
Abstract Spectra emitted from a wall-stabilized arc, running in a gas mixture of helium, argon, nitrogen, oxygen and traces of hydrogen have been studied. Intensities of selected spectral transitions of neutral nitrogen and oxygen have been measured. Applying the Boltzmann plot method and using a reliable set of O I transition probabilities of spectral lines, originating from levels considerably spread in excitation energies, the temperatures of arc plasmas have been determined. Line intensities of two N I infrared transitions, originating from doubly excited terms 3p′ 2 F o and 3p′ 2 G have been measured. In order to obtain the corresponding transition probabilities ( A ki ) for these line…
A “Voodoo Doll in Diapers”: Deconstructing the Cruel Child in Lionel Shriver’s We Need to Talk About Kevin (2003)
2018
This chapter examines the ways in which Lionel Shriver’s novel We Need to Talk About Kevin (2003) complicates mainstream representations of young high school shooters. The central argument is that Shriver offers her readers a critical and informed meta-perspective which conceives of childhood as a discursive construct. The chapter illustrates how constructivism arises as a highly ambivalent practice in the novel. One the one hand, it allows the novel to dissect and challenge the patterns according to which school shooters are commonly constructed in the media without, however, confirming any of them as Kevin’s “true” nature. On the other hand, the novel’s engagement with constructivism is b…
Exploring the Background: Puzzles, Afterthoughts, and Replies
2017
In this paper I review the comments, and reply to the objections, put forward in the commentaries to my essay “Pre-conventions. A fragment of the Background”, published in issues n. 30 and 33 of Revus – Journal for Constitutional Theory and Philosophy of Law. My remarks fall under the following headings: 1. The social dimension of pre-conventions; 2. Pre-conventions and ordinary habits and dispositions; 3. Whether my examples are mistaken; 4. Reasons and causes; 5. Normative facts; 6. Whether abstract entities can be causes; 7. Are pre-conventions conditions of Lewis-conventions? 8. What can pre-conventions do for legal theory? 9. Whether I discharged my argumentative burdens.

Fluorogenic detection of Tetryl and TNT explosives using nanoscopic-capped mesoporous hybrid materials
2013
[EN] A hybrid capped mesoporous material, which was selectively opened in the presence of Tetryl and TNT, has been synthesised and used for the fluorogenic recognition of these nitroaromatic explosives.
Aportaciones al estudio de la cerámica medieval valenciana. El proyecto de investigación arqueológica en las cubiertas de San Martín Obispo y San Ant…
2009
Una de las contribuciones más importantes que el Profesor Pedro López Elum ha realizado acerca de la cerámica medieval valenciana ha sido el estudio sistemático de las fuentes documentales, esperamos con este trabajo ampliar nuestro conocimiento sobre su empleo en el ámbito arquitectónico, a partir de las investigaciones arqueológicas que actualmente estamos llevando a cabo en las cubiertas de las Iglesia de San Martín Obispo y San Antonio Abad de Valencia.
Las torres del portal de Cuarte de Valencia y su función carcelaria
2007
Las torres de tos portales de Cuarte y de Serranos en la muralla cristiana de la ciudad de Valencia pudieron salvarse en la segunda mitad del Ochocientos a causa de albergar prisiones, mientras el resto del muro urbano estaba siendo inmolado. El presente artículo se ocupa de las primeras: sus comienzos constructivos y su historia penitenciaria desde el siglo XVII, así como su posterior destino guareciendo prisiones militares entre la década de 1820 y 1946. Además las torres de Cuarte fueron mudos testigos de ciertas reformas urbanas y otros acontecimientos. (A)
