Rhombi-chain Bose-Hubbard model: Geometric frustration and interactions
2018
We explore the effects of geometric frustration within a one-dimensional Bose-Hubbard model using a chain of rhombi subject to a magnetic flux. The competition of tunnelling, self-interaction and magnetic flux gives rise to the emergence of a pair-superfluid (pair-Luttinger liquid) phase besides the more conventional Mott-insulator and superfluid (Luttinger liquid) phases. We compute the complete phase diagram of the model by identifying characteristic properties of the pair-Luttinger liquid phase such as pair correlation functions and structure factors and find that the pair-Luttinger liquid phase is very sensitive to changes away from perfect frustration (half-flux). We provide some propo…
Archaeometric Characterisation of Decorated Pottery from the Archaeological Site of Villa dei Quintili (Rome, Italy): Preliminary Study
2019
This work focused on the study of decorated pottery dated back to the 16th century from the Roman archaeological site of Villa dei Quintili, a monumental complex located in the south-eastern part of Rome (Italy). A minero-petrographic and geochemical study was undertaken to analyse five archaeological samples in order to define textural features and raw materials used for their production, along with the chemical and physical composition of the superficial decorative glazed coatings. For this purpose, different analytical methods were used, such as polarising optical microscope (POM), X-ray diffraction (XRD), micro-Raman spectroscopy, X-Ray fluorescence (XRF), and electron microprobe analys…
The renaissance of tramways and urban redevelopment in France
2017
Abstract Tramways have made a remarkable comeback in France since the 1980s. An organization of public transport based on the decentralized administration system set up in the early 1980s has allowed local urban authorities to make their own choices to develop public transport networks in the context of automobile domination. As in many other countries, worries about fossil fuel dependency and demands concerning sustainable urban development appear as strong elements in favour of urban light rail. However, in France, tramways are not just technical solutions for traffic congestion, they have also become a symbol of a cultural mutation in urban development planning. Coupled with a national p…
Influencia de la velocidad de nombramiento en el inicio de la lectura
2016
Abstract:The analysis of the cognitive processes that are the basis of reading skill has detected some predictors of the development of phonological-orthographic skills necessary in learning it and has identified the naming speed as a good predictor of deficit related to reading difficulties. The objective of this study is to analyze the relationship between naming speed and initial learning of literacy through the analysis of aspects such as the influence of the reading habits, age of onset of literacy or participation in specific learning methods as Kumon. The study involved 289 children aged 4 to 6 years. Results showed naming speed correlates with phonological awareness, predicts readin…
The Images of the Others in Rome (and Geo-Climatic Determinism) (Le Immagini Dell'Altro a Roma (E Il Determinismo Climatico-Ambientale))
2008
In order to explain the anthropic differences of the foreign people, many Roman authors often make use of the well known theory of geo-climatic determinism. Within the frame of this theory Rome becomes the center of the world, i. e., the place of normality, culture, and identity. The Roman identity, however, is not exclusive and is deeply rooted in alterity. In fact, the foundation of Rome, seen as "conluvies convenarum", can always be repeated by means of the conquests of the "Other", who can easily become "identical".
Dissimilar Regulation of Antimicrobial Proteins in the Midgut of Spodoptera exigua Larvae Challenged with Bacillus thuringiensis Toxins or Baculoviru…
2015
Antimicrobial peptides (AMPs) and lysozymes are the main effectors of the insect immune system, and they are involved in both local and systemic responses. Among local responses, midgut immune reaction plays an important role in fighting pathogens that reach the insect body through the oral route, as do many microorganisms used in pest control. Under this point of view, understanding how insects defend themselves locally during the first phases of infections caused by food-borne pathogens is important to further improve microbial control strategies. In the present study, we analyzed the transcriptional response of AMPs and lysozymes in the midgut of Spodoptera exigua (Lepidoptera: Noctuidae…
Dubái: estrategias para una posible transición urbana
2020
The article presents the work "Dubai Pop-Up. Architecture in a transient city", the result of an international design workshop (coordinated by T. Aglieri Rinella and R. Garcia Rubio) which brought the Dubai question to the center, bringing together a large number of teachers and students to think how to introduce new ways of thinking about the city. Thanks to the diversified and sometimes surprising hypotheses that the projects developed suggest, it is clear how open the degree of alternatives to that development model only oriented on the “monoculture of profit” that has guided urban choices in this city up to now can still be.
RAÍCES MITOLÓGICAS EN LA ICONOGRAFÍA DE LA BELLA DURMIENTE EL CASO DE LA BELLA DURMIENTE DE WALT DISNEY
2020
Sleeping Beauty is a story we can all tell. A cursed princess who pricks herself and falls into a deep sleep until her prince wakes her up. But, like all stories, she has evolved into this form. If we trace its origins, the first time it was put down on paper was in the 13th century. Later, in the 14th century, three more versions were added. In the 17th century Giambattista Basile popularized it, but in that same century Perrault adapted it to his own way and in the 19th century the Brothers Grimm simplified it. Through all these forms there remains an essence, a common narrative, some characteristic elements that allow us to identify this story as the same one. And in them we …
Pioneras en escena : el Pioneer Club y el teatro británico de la década de 1890
2021
espanolLas artes escenicas fueron un ingrediente esencial en la actividad de los clubes femeninos de Londres a partir de la decada de 1890, que contribuyo a la renovacion del teatro britanico del cambio de siglo. Sin embargo, su presencia en estos espacios ha sido sistematicamente olvidada por la historia teatral del periodo. El objetivo de este articulo es trazar un mapeo de su influencia desde una triple perspectiva: ludico-formativa; como promotor de dramaturgas con escasa visibilidad en los circulos mas comerciales, y de renovacion escenica. Para esta ultima, acudimos al estudio de caso del Pioneer Club que, como concluiremos, nutrio el discurso progresista de los ibsenitas y movimiento…
El encuadre de los temas de salud: cobertura en prensa escrita del daño cerebral adquirido
2014
En este trabajo analizamos el encuadre informativo del Daño cerebral adquirido (DCA) en noticias publicadas en El País, El Mundo y La Vanguardia entre 2010 y 2013. Partiendo de una búsqueda léxica, se seleccionaron los textos que tematizaban el DCA, bien como tema central o secundario, y se analizaron las distintas categorías de encuadre discursivo. Los resultados muestran la escasa presencia del DCA en la prensa generalista, frente a su incidencia en nuestra sociedad, y que esta presencia escasa se refiere sobre todo a aspectos secundarios (prevención, necesidades asistenciales, calidad de vida), con especial magnificación de los avances tecnológicos. This paper analyzes the framing of Acq…
