Satyra na Augusta Zaleskiego czyli o sporze Wojciecha Wasiutyńskiego z „Syreną” paryską
2017
A SATIRE ON AUGUST ZALESKI, I.E. ON THE CONFLICT BETWEEN WOJCIECH WASIUTYŃŚKI AND THE PARISIAN SYRENA In 1949 the Parisian weekly Syrena published an anonymous satire on President August Zaleski. As it later turned out, it was written by Wojciech Wasiutynski, a well-known journalist and activist of the Stronnictwo Narodowe (National Party). Wasiutynski was not informed about the decision to publish his text and was outraged, demanding compensation. The editorial team explained that the anonymous copies of the satire had circulated among Polish immigrants. The issue echoed a far more significant debate concerning the office of the President of Poland in exile.

La productividad científica sobre MOOC: aproximación bibliométrica 2012-2016 a través de SCOPUS
2017
Los Massive Online Open Courses (MOOC) han supuesto un hito en la educacion online en los ultimos cinco anos. La proliferacion de cursos y plataformas para su difusion han hecho que el fenomeno no solo sea un punto de reflexion educativa, social y politica, sino que tambien pase a la esfera academica como objeto de investigacion. El presente estudio analiza la productividad cientifica del fenomeno MOOC a partir del analisis de 752 publicaciones indexadas en la base de datos SCOPUS en el periodo 2012-2016. Los datos extraidos permiten realizar una radiografia global del estado del fenomeno, la evolucion que ha sufrido en los ultimos anos, el tipo de publicaciones que sustentan el fenomeno, l…
CONTROVERSIAS EN TORNO AL SOFTWARE LIBRE: PRÁCTICAS Y DISCURSOS EN LA DOCENCIA UNIVERSITARIA VALENCIANA
2008
Resumen basado en el de la publicación La progresiva implantación del software libre en los ámbitos universitarios, se acompaña de un discurso construido sobre las controversias que rodean a esta tecnología. Para el análisis de este problema se utiliza el modelo de 'espacios controversiales' propuesto por Nudler, definiendo uno de estos espacios en torno a la aplicación de las tecnologías informáticas en las enseñanzas universitarias. El supuesto es que el debate sobre el copyleft está alcanzando también al discurso pedagógico que acompaña a las aplicaciones de estas tecnologías. Este modelo es el que se trata de aplicar al estudio de cómo se formulan tales controversias en la difusión del …
Cloud droplets to drizzle: Contribution of transition drops to microphysical and optical properties of marine stratocumulus clouds
2017
Aircraft measurements of the ubiquitous marine stratocumulus cloud type, with over 3000 km of in situ data from the Pacific during the Cloud System Evolution in the Trades experiment, show the ability of the Holographic Detector for Clouds (HOLODEC) instrument to smoothly interpolate the small and large droplet data collected with Cloud Droplet Probe and 2DC instruments. The combined, comprehensive instrument suite reveals a surprisingly large contribution in the predrizzle size range of 40–80 μm (transition droplets, or drizzlets), a range typically not measured and assumed to reside in a condensation-to-collision minimum between cloud droplet and drizzle modes. Besides shedding light on t…
Extinction and optical depth of contrails
2011
[1] One factor limiting the understanding of the climate impact from contrails and aircraft induced cloud modifications is the accurate determination of their optical depth. To this end, 14 contrails were sampled for 2756 s with instruments onboard the research aircraft Falcon during the CONCERT (CONtrail and Cirrus ExpeRimenT) campaign in November 2008. The young (<10 min old) contrails were produced by 9 commercial aircraft with weights of 47 to 508 t, among them the largest operating passenger aircraft, the Airbus A380. The contrails were observed at temperatures between 214 and 224 K and altitudes between 8.8 and 11.1 km. The measured mean in-contrail relative humidity with respect to i…
PROBING THE DARK MATTER RADIAL PROFILE IN LENS GALAXIES AND THE SIZE OF X-RAY EMITTING REGION IN QUASARS WITH MICROLENSING
2015
We use X-ray and optical microlensing measurements to study the shape of the dark matter density profile in the lens galaxies and the size of the (soft) X-ray emission region. We show that single epoch X-ray microlensing is sensitive to the source size. Our results, in good agreement with previous estimates, show that the size of the X-ray emission region scales roughly linearly with the black hole mass, with a half-light radius of where . This corresponds to a size of or ?1 lt-day for a black hole mass of . We simultaneously estimated the fraction of the local surface mass density in stars, finding that the stellar mass fraction is ? = 0.20 ? 0.05 at an average radius of , where Re is the …
Ground-Based measurements of the 2014-2015 holuhraun volcanic cloud (Iceland)
2018
he 2014–2015 Bárðarbunga fissure eruption at Holuhraun in central Iceland was distinguished by the high emission of gases, in total 9.6 Mt SO2, with almost no tephra. This work collates all ground-based measurements of this extraordinary eruption cloud made under particularly challenging conditions: remote location, optically dense cloud with high SO2 column amounts, low UV intensity, frequent clouds and precipitation, an extensive and hot lava field, developing ramparts, and high-latitude winter conditions. Semi-continuous measurements of SO2 flux with three scanning DOAS instruments were augmented by car traverses along the ring-road and along the lava. The ratios of other gases/SO2 were …
Choix du système électoral et Convention européenne des droits de l'homme : quelques observations à la lumière d'une affaire concernant une loi élect…
2013
Within the space of less than two years the European Court of Human Rights and the Italian Constitutional Court have returned almost opposing judgments on the question of the observance of political rights by Italy’s 2005 electoral law. The ECHR found the applications made to it by groups of electors inadmissible given the manifestly ill-founded character of the grievances they were based on. The Constitutional Court, on the contrary, concluded that the law was unconstitutional. At first sight, the differing approaches by the two courts and the differing conclusions they reached may be viewed as an expression of the complementary nature of the European system of protection of human rights w…
Industry 4.0: Advanced digital solutions implemented on a close power loop test bench
2021
Abstract The paradigm of Industry 4.0 allows to increase the efficiency and effectiveness of the production. Companies that will implement advanced solutions in production systems will increase their level of competitiveness and will be able reach high market shares. The present paper is focused on the development of advanced digital solutions to be implemented on a close power loop test bench designed to test high power transmissions for naval unit. In particular, the test configuration consists of a back-to-back connection between two identical mechanical reducers. Since the efficiency of these systems are very high, it is not necessary to use large electric motors, thus managing to conta…
