Supercontinuum generation in chalcogenides : application to gas spectroscopy in atmospheric band III

2023

This thesis work aims to contribute to the development of new fiber sources emitting over a wide range of wavelengths in the IR, in particular to detect greenhouse gases in the mid-infrared range. Our spectroscopy results with nitrous oxide N2O and methane CH4 are obtained in band III. To achieve this, the generation of supercontinuum (SC) covering band III was made possible by using chalcogenide optical fibers, purified and free of highly toxic elements according to REACH regulations, in particular arsenic and antimony. The fibrable vitreous composition belonging to the Ge-Se-Te ternary system fits perfectly into the context of sustainable development, it is the one that has been identifie…

Synthesis of molecular materials and heterojunctions, on the interest of ambipolar materials in conductometric gas sensors

2017

The molecular semiconductors have enabled the production of electronic devices such as field effect transistors, diodes and other heterojunctions. The ambipolar materials, capable of carrying both positive charges and negative, result in devices with special properties. The purpose of this thesis is to synthesize new ambipolar materials develop original electronic devices, especially for applications in the field of gas sensors. We are interested in molecules capable to lead to thin films with low temperature techniques known as solution processing, particularly metallo-phthalocyanines.

TCR V alpha chain expression influences reactivity to the hapten TNP.

1997

We have recently demonstrated a remarkable selection of in vitro cultivated, TNP-specific polyclonal T cell lines for the expression of a TCR beta chain encoded by the V beta 8.2 gene. The goal of the present study was to analyse V alpha usage in V beta 8.2 T cells responsive to TNP, using TNP-specific T cell lines derived from three common strains of mice, as well as from V beta 8.2 transgenic mice. Results indicate that in vitro TNP stimulation of T cells from TNP-immune mice results in significant skewing of V alpha usage among responding V beta 8.2+ T cells, with overexpression observed for V alpha 3.2 and V alpha 8. These results indicate that V alpha expression influences recognition …

Appropriazione e (ri)semantizzazione dello spazio urbano: lo sport in una piazza palermitana

2019

Il contributo, attraverso uno studio di campo, con un approccio geografico culturale esplora le modalità attraverso cui uno spazio urbano, piazza Vittorio Emanuele Orlando a Palermo, può essere oggetto di complessi processi di (ri)semantizzazione. La piazza diviene infatti luogo per sport giovanili improvvisati, al centro di dialettiche opposte (ufficialità/improvisazione) e di forme multistratificate di socialità e aggregazione.

The chapter through a field study with a cultural geographical approach explores the ways in which urban space Piazza Vittorio Emanuele Orlando in Palermo can be the subject of complex processes of (re) semantization. In fact the square becomes a place for improvised youth sports at the center of opposing dialectics (official/improvisation) and multi-layered forms of socializing and aggregation.

Ultreya, suseya, Santiago!” Viaggio e spazialità ne La ballata dei pellegrini

2020

Per studiare dal punto di vista della geografia culturale alcuni aspetti del pellegrinaggio a Santiago de Compostela, in Spagna, il capitolo prende in considerazione un testo letterario, il romanzo autobiografico "La ballata dei pellegrini" della scrittrice francese Edith De La Héronnière, pubblicato per la prima volta nel 1993 e tradotto in italiano nel 2004. Il romanzo racconta l’esperienza del pellegrinaggio giacobeo effettuato dall’autrice negli anni Novanta assieme a tre compagni di viaggio partendo da un cammino francese. In particolare, attraverso l’analisi di alcune parti del testo, si indagano le modalità attraverso le quali la narrazione costruisce e descrive lo spazio fisico e si…

The contribution critically and from a geographical perspective discusses the connection between propaganda comics and cartoons in the period of twentieth-century totalitarianisms. The way in which space real and symbolic is implicated through the rhetoric and dialectics of power in social economic and identity dynamics is then explored. In order to study some aspects of the pilgrimage to Santiago de Compostela from the point of view of cultural geography in Spain the chapter takes into consideration a literary text the autobiographical novel "The pilgrims' ballad" by the French writer Edith De La Héronnière first published in 1993 and translated into Italian in 2004. The novel recounts the experience of the Jacobean pilgrimage carried out by the author in the nineties together with three traveling companions starting from a French journey. In particular through the analysis of some parts of the text the ways in which the narration constructs and describes the physical and symbolic space of the pilgrimage are investigated. In this way it is possible to explore the way in which peculiar attributions of meaning inscribe the experience of pilgrimage in a symbolic universe that is both personal and collective at the same time.

The Effect of Music on Movement Perception: Synchresis in Hits for HIIT

2021

Hits for HIIT consists in a research-creation project aiming to produce both musical pieces and training exercises for, on the one hand, optimizing HIIT practice and, on the other, enriching scholarly research on the relations between music and sports. These questions and their related studies have highlighted music/movement relations and the way they are perceived. In this paper we would like to outline how we attempt to build a two-way dialogue between the production of music adapted to HIIT and the design of workouts based on the music.

Síntesis de haptenos y bioconjugados de anatoxina-a para el desarrollo de métodos inmunoquímicos

2016

La anatoxina-a es una potente neurotoxina producida por cianobacterias de agua dulce. Bajo ciertas condiciones ambientales, estos microorganismos son capaces de proliferar de forma masiva, dando lugar a floraciones o blooms, liberando concentraciones importantes de anatoxina-a. La presencia de esta biotoxina en ecosistemas de agua dulce ha causado episodios de intoxicación en humanos, así como un elevado número de incidentes mortales en ganado, animales domésticos y fauna salvaje. La posibilidad de detectar la presencia de bajas concentraciones de anatoxina-a en fuentes de abastecimiento de agua, en aguas de uso recreativo o incluso en alimentos, constituye una eficaz aproximación para redu…

Increased expression of ICAM-1, E-selectin, and VCAM-1 by cultured human endothelial cells upon exposure to haptens.

1992

Contact allergens induce several accessory signals which promote the activation of antigen-specific T cells. One of these signals is the increased expression of adhesion molecules on antigen-presenting cells and endothelial cells. Epicutaneous application of non-toxic doses of 2,4-dinitrofluorobenzene (DNFB) onto the skin of non-sensitized individuals elicited progressive staining for ICAM-1 on dermal microvascular endothelial cells. To elucidate the question of whether contact allergens can act directly on endothelial cells to elevate their expression of surface structures that bind leukocytes, confluent monolayers of human umbilical vein endothelial cells were incubated with the contact a…
