Travail, travailleurs et ouvriers d'Europe au XXe siècle
2016
International audience; "Ouvriers et travailleurs sont des figures bien connues, mais leurs contours n'ont cessé d'évoluer aux XIXe et XXe siècles en Europe. À partir d'un réexamen de la manière dont on a écrit leur histoire, le propos de cet ouvrage ambitieux est de redessiner ces figures. Rassemblant une vingtaine des meilleurs spécialistes de huit pays, le livre montre sous un jour nouveau ces hommes et ces femmes, engagés dans des métiers et des activités exigeantes, à travers des territoires, depuis les Asturies jusque dans la vallée de la Clyde écossaise, ou des thématiques, la santé ou le chômage, les statuts ou les mobilisations. Par là, en même temps qu'une histoire plurielle du tr…

From the South. Ernesto Basile's Routes and Destinations
2014
Except for a few gaps, the Basile's archive is one of the best maintained contemporary architectural archives in Europe. Basile wrote extensively about his travels and discussed their context and significance. The documents range from reports on the World Exhibition in Paris in 1878, to stories of Ortensio Lando, the sixteenth-century Italian humanist and traveler, who moved "from the far Sicily to the edge of the Alps".

Evanescent wave-initiated photopolymerisation as a new way to create monolithic open-tubular capillary columns: use as enzymatic microreactor for on-…
2010
Evanescent wave-initiated photopolymerisation in an optically wave guiding PTFE-coated fused silica capillary using light-emitting diode as a light source, is established here as a way to fabricate monolithic porous layer open-tubular capillary columns with a potential in capillary separation methods; application of the obtained open-tubular columns as enzymatic microreactors for on-line protein digestion is demonstrated.
Optical Dark Rogue Wave
2016
AbstractPhotonics enables to develop simple lab experiments that mimic water rogue wave generation phenomena, as well as relativistic gravitational effects such as event horizons, gravitational lensing and Hawking radiation. The basis for analog gravity experiments is light propagation through an effective moving medium obtained via the nonlinear response of the material. So far, analogue gravity kinematics was reproduced in scalar optical wave propagation test models. Multimode and spatiotemporal nonlinear interactions exhibit a rich spectrum of excitations, which may substantially expand the range of rogue wave phenomena and lead to novel space-time analogies, for example with multi-parti…
Crucial dependence of excimer laser toughness of “wet” silica on excess oxygen
2011
Creation of point defects by ArF (6.4 eV) and F2 laser (7.9 eV) irradiation in synthetic “wet” silica glass thermally loaded with interstitial O2 molecules was studied by optical absorption, electron paramagnetic resonance and infrared absorption. The presence of excess oxygen caused a significant increase of laser-induced ultraviolet (UV) absorption, which was 4 times (7.9 eV-irradiation) and > 20 times stronger (ArF irradiation) as compared to O2-free samples. The spectral shape of photoinduced absorption nearly completely coincided with the spectral shape of oxygen dangling bonds (NBOHC) in 3 to 6.5 eV regions. The contribution of Si dangling bonds (E' centers) was less than few % and wa…
News about the Aragonese Botanist Martín Sessé Lacasta
2018
Se dan noticias del paso por la Universidad de Zaragoza y por América del médico y naturalista aragonés Martín Sessé Lacasta, que impulsó desde América la Expedición Botánica de Nueva España, así como la creación del Jardín botánico de México. Se trata de una de las personalidades que más han prestigiado la labor científica de España en América. / News about the stay of the Aragonese doctor and naturalist Martín Sessé Lacasta both in the Universidad de Zaragoza and Central America. He was part of the Botanical Expedition in Nueva España where he promoved Botanical studies and helped creating the Botanical Garden in Mexico. He is one of the most important Spanish scientist who spread Science…
Protocols for UV camera volcanic SO2 measurements
2010
Abstract Ultraviolet camera technology offers considerable promise for enabling 1 Hz timescale acquisitions of volcanic degassing phenomena, providing two orders of magnitude improvements on sampling frequencies from conventionally applied scanning spectrometer systems. This could, for instance enable unprecedented insights into rapid processes, such as strombolian explosions, and non-aliased corroboration with volcano geophysical data. The uptake of this technology has involved disparate methodological approaches, hitherto. As a means of expediting the further proliferation of such systems, we here study these diverse protocols, with the aim of suggesting those we consider optimal. In part…
