Il catalano nella Corte Aragonese di Napoli, riflesso in documenti bilingui della cancelleria di Ferrante. Uno studio storico-sociale
2013
Riassunto: Nel presente lavoro viene analizzato il fenomeno del code switching in una prospettiva storico-sociale. In particolare, focalizzeremo la nostra attenzione su cinque lettere bilingui del Codice Aragonese (1458-1460), un registro cancelleresco della corte aragonese a Napoli, in cui si passa dal catalano o dal castigliano al napoletano e viceversa. Analizzando il contesto storico e sociale nel quale le lettere sono state scritte, proveremo a trarre delle conclusioni sulle motivazioni per cui si è realizzato il rispettivo cambio di codice linguistico. Nello stesso modo cercheremo di spiegare la tendenza di esprimersi in catalano in situazioni emozionali o di tensione politica, ma anc…
Musician angels. Study of the narrative evangelic iconographic types
2012
El presente artículo pretende ofrecer una nueva vía de análisis de las imágenes musicales a través del estudio de los tipos iconográficos y las fuentes literarias e icónicas que los configuran. En este caso se ha optado por realizar un estudio del tipo del ángel músico en la narración evangélica y las razones de su inclusión en los diferentes tipos narrativos del arte visual cristiano. The aim of this article is to offer a new way to analyse musical images trough the study of iconographic types and their literary and iconic sources. More precisely, this paper focuses on the apparition of the musician angel in the narrative evangelic context and the reasons for its inclusion in the various n…
Using ultrasound transmission velocity to analyse the mechanical properties of teeth after in vitro, in situ, and in vivo irradiation.
2000
Ultrasound transmission velocity (UTV) in isotropic material as a measure for the modulus of elasticity was correlated to mechanical properties. Changes in micromechanical properties of radiated teeth and influence of the oral cavity were to be evaluated nondestructively. UTV was measured in extracted teeth after 36 Gy and 62 Gy of in situ (enorally, with no contact to the oral cavity) and in vitro irradiation. Relative to controls, teeth subjected to 62 Gy in vivo showed higher UTV values for dentine and enamel. Sound teeth irradiated with 60 Gy in situ also showed higher UTV values for enamel, whereas dentine values were not significantly different from those of control. The mechanical pr…
The Dark Trienium: Valencia, 1389-1391. Unrest coinciding with an assault on the Jewish district
2012
Estudio de base documental sobre el auge del antijudaísmo desde 1371 y el asalto a la judería de Valencia en julio de 1391, al poco tiempo de su ampliación. Sitúa el hecho en el contexto de las tensiones políticas en la Corona de Aragón y en la ciudad, donde se enfrentaban sendos bandos: actuaciones entre 1375 y 1392 del inquisidor Nicolau Eimeric (Directorium inquisitorum) contra herejes y su condena de obras de Ramon Llull. Cortes de 1388-1389. Guerras en el ámbito pirenaico en 1390. Políticas de abastecimiento y defensa de la ciudad de Valencia y oposición de villas y nobles del reino al municipio de la capital, que arma una milicia montada en mayo de 1391. Represión de maleantes y medid…
Automatic detection and agronomic characterization of olive groves using high-resolution imagery and LIDAR data
2014
The Common Agricultural Policy of the European Union grants subsidies for olive production. Areas of intensified olive farming will be of major importance for the increasing demand for oil production of the next decades, and countries with a high ratio of intensively and super-intensively managed olive groves will be more competitive than others, since they are able to reduce production costs. It can be estimated that about 25-40% of the Sicilian oliviculture must be defined as “marginal”. Modern olive cultivation systems, which permit the mechanization of pruning and harvest operations, are limited. Agronomists, landscape planners, policy decision-makers and other professionals have a grow…
Prediction of the mesiodistal size of unerupted canines and premolars for a group of Romanian children: a comparative study
2013
Objectives The aim of the present study was to develop an optimization method of multiple linear regression equation (MLRE), using a genetic algorithm to determine a set of coefficients that minimize the prediction error for the sum of permanent premolars and canine dimensions in a group of young people from a central area of Romania represented by a city called Sibiu. Material and Methods To test the proposed method, we used a multiple linear regression equation derived from the estimation method proposed by Mojers, to which we adjusted regression coefficients using the Breeder genetic algorithm. A total of 92 children were selected with complete permanent teeth with no clinically visible …
Accuracy of the estimation of dental age in comparison with chronological age in a Spanish sample of 2641 living subjects using the Demirjian and Nol…
2016
Age estimation is an important procedure in forensic medicine and is carried out for a number of reasons. For living persons, age estimation is performed in order to assess whether a child has attained the age of criminal responsibility, in scenarios involving rape, kidnapping or marriage, in premature births, adoption procedures, illegal immigration, pediatric endocrine diseases and orthodontic malocclusion, as well as in circumstances in which the birth certificate is not available or the records are suspect. According to data from the UNHCR (United Nations High Commissioner for Refugees), the number of people seeking refugee status continued to increase in the last years, driven by the w…
A study on stress distribution to cement layer and root dentin for post and cores made of CAD/CAM materials with different elasticity modulus in the …
2019
Background To evaluate the stress distribution in a maxillary central incisor with different post and cores made of six CAD/CAM materials with different elastic modulus in the absence of ferrule using the finite element analysis. Material and methods A three-dimensional endodontically treated maxillary central incisor restored with an all-ceramic crown was modelled in Rhinoceros (5.0 SR8, McNeel). The geometries were analyzed in ANSYS 17.2 (ANSYS Inc.) considering isotropic, homogeneous, linearly elastic materials with perfectly bonded contacts. The elastic moduli (E) of the post-and-cores defined the groups to be compared: nanoceramic resin (E=12.8GPa); composite resin (E=16GPa); hybrid ce…
Are Metal-Free Monolithic Crowns the Present of Prosthesis? Study of Mechanical Behaviour
2019
Purpose: To analyze in vitro the mechanical behavior of five types of complete coverage crowns fabricated from different materials. Materials and methods: Seventy-five full coverage crowns were divided into five groups according to material: Group I, metal core with feldspathic ceramic covering (MC- control group)
Decreased dentin tubules density and reduced thickness of peritubular dentin in hyperbilirubinemia-related green teeth.
2016
BACKGROUND It is stated anecdotally that patients with liver diseases in childhood who develop green teeth have increased risk for rampant caries, which may be secondary to changes in dental structure. The aim of this study was to test the hypothesis that hyperbilirubinemia affects the dentin morphology of green teeth. MATERIAL AND METHODS Sixteen primary teeth were prepared and divided into two groups (green teeth, n = 8 and control, n = 8), which were transversely fractured across the cervical third of the dental crowns; dentin was prepared and sputter-coated with gold, and examined under a scanning electron microscope. The mean density and mean diameter of dentin tubules, as well as the …
