Sobre los límites entre capítulos en el Amadís de Gaula y en las Sergas de Esplandián
2013
En estas páginas se parte del problema planteado por una anomalía observada en dos capítulos del Amadís de Gaula de Rodríguez de Montalvo, para pasar a un examen de la distribución de los capítulos en esta obra y en las Sergas de Esplandián y proponer una solución: la muy posible influencia del Tirant lo Blanc y su relación con el tópico de las aventuras en el Imperio Bizantino.

Kindergarten children's argumentation in reflection symmetry: The role of semiotic means
2017
International audience; In this paper I investigate the characteristics of children's argumentation when they work with reflection symmetry. Using Toulmin's (2003) model for substantial argumentation, I illuminate structural aspects of the ongoing argumentation. In addition, I analyse the children's argumentation with respect to their use of semiotic means. Results show that children are able to argue for a claim in a quite complex manner. The study also illustrates the extensive use of semiotic means in children's argumentation. In every element in the argumentative structure, children use gestures and other semiotic means to mediate their ideas. It is actually impossible to make sense of …
Historical and Technical Notes on Aqueducts from Prehistoric to Medieval Times
2013
The aim of this paper is to present the evolution of aqueduct technologies through the millennia, from prehistoric to medieval times. These hydraulic works were used by several civilizations to collect water from springs and to transport it to settlements, sanctuaries and other targets. Several civilizations, in China and the Americas, developed water transport systems independently, and brought these to high levels of sophistication. For the Mediterranean civilizations, one of the salient characteristics of cultural development, since the Minoan Era (ca. 3200-1100 BC), is the architectural and hydraulic function of aqueducts used for the water supply in palaces and other settlements. The M…
Gamma-Ray Flares from Mrk421 in 2008 observed with the ARGO-YBJ detector
2010
In 2008 the blazar Markarian 421 entered a very active phase and was one of the brightest sources in the sky at TeV energies, showing frequent flaring episodes. Using the data of ARGO-YBJ, a full coverage air shower detector located at Yangbajing (4300 m a.s.l., Tibet, China), we monitored the source at gamma ray energies E > 0.3 TeV during the whole year. The observed flux was variable, with the strongest flares in March and June, in correlation with X-ray enhanced activity. While during specific episodes the TeV flux could be several times larger than the Crab Nebula one, the average emission from day 41 to 180 was almost twice the Crab level, with an integral flux of (3.6 +-0.6) 10^-1…
Constraints on neutrino emission from nearby galaxies using the 2MASS redshift survey and IceCube
2020
The distribution of galaxies within the local universe is characterized by anisotropic features. Observatories searching for the production sites of astrophysical neutrinos can take advantage of these features to establish directional correlations between a neutrino dataset and overdensities in the galaxy distribution in the sky. The results of two correlation searches between a seven-year time-integrated neutrino dataset from the IceCube Neutrino Observatory, and the 2MASS Redshift Survey (2MRS) catalog are presented here. The first analysis searches for neutrinos produced via interactions between diffuse intergalactic Ultra-High Energy Cosmic Rays (UHECRs) and the matter contained within …
Multi-channel search for squarks and gluinos in root s=7 TeV pp collisions with the ATLAS detector at the LHC
2013
A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb[superscript −1] of √s = 7 TeV pp collisions produced by the Large Hadron Collider and recorded by the ATLAS detector is presented. The search uses a set of variables carrying information on the event kinematics transverse and parallel to the beam line that are sensitive to several topologies expected in supersymmetry. Mutually exclusive final states are defined, allowing a combination of all channels to increase the search sensitivity. No deviation from the Standard Model expectation is observed. Upper limits at 95 % confidence level…
Angioimmunoblastic T-cell lymphoma
2008
Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive neoplasm clinically characterized by sudden onset of constitutional symptoms, lymphadenopathy, hepatosplenomegaly, frequent autoimmune phenomena, particularly hemolytic anemia and thrombocytopenia, and polyclonal hypergammaglobulinemia. The lymph node histological picture is also distinctive, constituted by a polymorphic infiltrate, a marked proliferation of high endothelial venules, and a dense meshwork of dentritic cells. The neoplastic CD4+ T-cells represent a minority of the lymph node cell population; its detection is facilitated by the aberrant expression of CD10. Almost all cases arbor an EBV infected B-cell populatio…
Systems of attention to childhood education in Latin America and The Caribbean (AL & C)
2019
El propósito de este artículo se centra en conocer cómo se estructuran los sistemas educativos de los países de América Latina y la Región de Caribe respecto al tramo de la primera infancia. Se llevó a cabo el análisis de diversos informes internacionales y documentos oficiales sobre los avances de los programas en cuanto a cobertura, inversión, regulaciones, entre otros. La naturaleza de carácter documental de este trabajo permite una aproximación comparada entre los países acerca del modo en que aborda la escolarización de la primera infancia en cada país de la región. Uno de los logros más destacados es el vinculado a la expansión del primer nivel educativo y a la cobertura alcanzada. Ca…
«Povera, buona, malinconica Italia». Le cartografie di Orio Vergani
2019
Un'intensa urgenza di ricostruzione si ritrova nelle pagine di Orio Vergani dedicate alle imprese ciclistiche di Fausto Coppi, in cui la cronaca sportiva si fonde al racconto del tormentato ventennio che va dal 29 maggio del 1940 sino alla morte del «campionissimo», nel gennaio del 1960. In tale ‘narrazione’, che coopera a delineare un percorso ideologico e politico di adesione al fascismo mai negato dallo scrittore ma vissuto, soprattutto a ridosso della guerra, in modo problematico, il trattamento dello spazio riveste una centralità conoscitiva ed intepretativa fondante, configurando topografie in cui spaccato documentario, analisi societaria, suggestione narrativa coesistono. Nell’immedi…
