Homodyne Solid-State Biased Coherent Detection of Ultra-Broadband Terahertz Pulses with Static Electric Fields.

2021

We present an innovative implementation of the solid-state-biased coherent detection (SSBCD) technique, which we have recently introduced for the reconstruction of both amplitude and phase of ultra-broadband terahertz pulses. In our previous works, the SSBCD method has been operated via a heterodyne scheme, which involves demanding square-wave voltage amplifiers, phase-locked to the THz pulse train, as well as an electronic circuit for the demodulation of the readout signal. Here, we demonstrate that the SSBCD technique can be operated via a very simple homodyne scheme, exploiting plain static bias voltages. We show that the homodyne SSBCD signal turns into a bipolar transient when the stat…

A new geochemical approach to estimate the distribution of air pollutants from natural and anthropogenic sources: examples from Solfatara Crater (Cam…

2015

Volcanic and geothermal systems significantly contribute to the input of volatile contaminants, such as mercury and hydrogen sulfide, into the atmosphere. Mercury has a strong environmental impact. In the atmosphere the prevalent elemental form is Hg0 (~98 %), whose main physical-chemical features are: high volatility, low solubility and chemical inertness. Hydrogen sulfide (H2S), one of the most abundant gas compounds in volcanic fluids, is highly poisoning and corrosive and unpleasantly smells of rotten eggs. Measurements of Hg0 and H2S concentrations in air are commonly performed by means of passive samplers. However, real-time measurements, coupled with monitoring of local atmospheric c…

Probing Planck scale physics with IceCube

2005

Neutrino oscillations can be affected by decoherence induced e.g. by Planck scale suppressed interactions with the space-time foam predicted in some approaches to quantum gravity. We study the prospects for observing such effects at IceCube, using the likely flux of TeV antineutrinos from the Cygnus spiral arm. We formulate the statistical analysis for evaluating the sensitivity to quantum decoherence in the presence of the background from atmospheric neutrinos, as well as from plausible cosmic neutrino sources. We demonstrate that IceCube will improve the sensitivity to decoherence effects of ${\cal O}(E^2/M_{\rm Pl})$ by 17 orders of magnitude over present limits and, moreover, that it ca…

Los edificios universitarios de Fernando Moreno Barberá en el campus de Blasco Ibáñez de Valencia: nuevas aportaciones a su cronología y construcción

2018

Este artículo estudia el conjunto de edificios construidos por el arquitecto Fernando Moreno Barberá en el campus universitario de Blasco Ibáñez de Valencia, cuyos proyectos se redactaron entre el final de los años cincuenta y primeros sesenta del siglo XX. Este artículo se ha elaborado a partir del estudio de las fuentes originales, sobre todo de las actas de las sesiones celebradas por la Junta de Obras de la Universidad de Valencia; se trata de documentos inéditos que describen con exactitud el proceso constructivo de este espacio tan singular.

The Nuremberg Trial in the Finnish Press Discourse

2011

The opening of the Nuremberg Trial was widely reported in Finland, as in other countries examined here. Like the reportage from the liberated concentration camps, the Finnish press was not represented on the spot although it had a quota for one journalist. However, the trial was a much-awaited event in Finland. The Belsen Trial (the trial of Josef Kramer and 44 others), which had ended on 17 November 1945, was duly reported in Finland, and in part indicated that the interest in Nazi criminality was running high.1

The Finnish Press and the Liberation of the Concentration Camps

2011

Finland’s response to the liberation of the concentration camps was considerably different from the British and Swedish responses; the Finnish press wrote far less about the liberations than their British and Swedish counterparts; the event hardly sparked any public discussions in Finland; and there was almost no pictorial record of the atrocities to accompany the news. The purpose of this chapter is twofold: first, to establish what the Finnish press wrote about the liberation of the camps — to investigate what type of discourses the Finnish press subscribed to; and second, to analyse why they wrote in the way they did — to understand why the news was framed in certain ways.

“I feel, I know, I am immortal”: literary works in the newspapers of Soviet prisons and camps in the 1920s

2021

Abstract The present article sheds new light on the newspapers and other publications of the Soviet prison camps in the 1920s and early 1930s. The first part reconstructs the institutional dynamics that brought about the publication of newspapers, wall newspapers and other periodicals produced inside the camps. The article then focuses on a selection of literary works published by inmates and on the importance of Soviet newspapers published in places of detention as a source for the study not only of the history of the Gulag, but also of its culture and literature.

Rodrigo de Mendoza, I Marqués del Cenete y I Conde del Cid: paralelismos entre su biografía y su pretendida genealogía = Rodrigo de Mendoza, First Ma…

2018

El Gran Cardenal de España quiso, al legitimar a sus hijos nacidos de sendas relaciones ilícitas, consolidarlos como miembros de la nobleza castellana. Así fue, por ejemplo, con su primogénito Rodrigo, I marqués del Cenete y I conde del Cid, emparentado por voluntad paterna con Rodrigo Díaz de Vivar, el Cid Campeador. Al apropiarse de esta ficticia genealogía, el prelado dotaba al mayorazgo legado a éste de un simbolismo que, a medida que el marqués fue madurando y curtiéndose en las guerras de Granada, las campañas italianas y las Germanías de Valencia, cobraba mayor verosimilitud a través de sus actos y acciones. El objeto de este trabajo es aproximarnos al perfil biográfico de Rodrigo de…

Religious thought and experience in the prison camps

2020

The development of religious thought has often been marked by discord and conflicts be tween religions (and/or individual religious thinkers) and the State, which at times led to the repression of individuals and or groups of people united by the same confession. The Russian case is fully in line with this unfortunate tradition: from Nikon’s schism to the re pression against all religions under the Soviet regime, Russian religious thought has of ten developed in repressive conditions. However, the Russian case has one distinguishing feature, that is, the extensive use of prison camps by Russian and Soviet authorities from the nineteenth century onwards, which has had a direct effect on some…

Trauma y denuncia en los testimonios del exilio chileno

2009

El artículo analiza el rol cumplido por los testimonios que los supervivientes de los campos de concentración chilenos publicaron en el exilio en los años siguientes al golpe de estado de 1973, que dio origen a la dictadura de Pinochet. El artículo se centra en dos elementos principales. Por una parte, el papel de los testimonios en las estrategias de denuncia internacional contra la dictadura. Por otra, el modo en que los supervivientes utilizaron la escritura testimonial para elaborar y dar un sentido narrativo al trauma experimentado en los campos de concentración. The article analizes the role accomplished by the testimonies of survivors of concentration camps in Chile, wich were publis…
