Different approaches to marriage downgrading : from an anti-elusive measure to an antidiscriminatory claim
2021
The essay focuses on the different mechanisms of marriage downgrading. Given the principle of ?cross-border continuity? of statuses, limits to this continuity are sometimes admitted and they are placed through downgrading mechanisms. That can occour in the case of same-sex marriages transcription in a Member State which does not allow such marriages, but which does allow samesex registered partnerships. Downgrading mechanism has an anti-elusive function, but it is not without problems in terms of discrimination on the grounds of sexual orientation. A different approach is taken in the case of an opposite-sex couple requesting the downgrading of their marriage, celebrated before the Member S…
Posttraumatic carotid-cavernous fistula: Pathogenetic mechanisms, diagnostic management and proper treatment. A case report.
2016
Journal Article; UNLABELLED Carotid-cavernous fistulas are an uncommon diseases characterized by abnormal communications between arteries and veins located in the cavernous sinus. According with Barrow´s classification they could be divided in two groups: direct and indirect. The typical symptoms showed by theses pathologies are: pulsating exophthalmos and orbital blow. The present study describes a case of direct posttraumatic carotid-cavernous fistula in a 26 years old man. Furthermore, we present the images that we used to make the diagnosis. In this light, we decided to treat this case with endovascular approach after considering several therapeutic options. The aim of the present repor…
Investigation of molecular states with charm and beauty hadrons
2014
La Fisica de hadrones ha tenido un desarrollo espectacular en los ultimos años debido a la pletora de estados nuevos que han sido descubiertos en laboratorios como BES en Beijing, la colaboracion Babar en USA, Belle en Japon, CLEO en USA y el CERN en Europa, entre otros. El modelo de quarks, segun el cual los mesones estan formados de quark antiquark y los bariones de tres quarks, tuvo en su dia un valor incalculable, al permitir entender los hadrones en terminos de unos pocos componentes elementales. Las predicciones que hizo, y fueron confirmadas, puso este modelo de los hadrones en un lugar incuestionable de la Historia de la Fisica. Sin embargo, el paso del tiempo nos ha ido enseñando q…
Particle identification in ALICE: a Bayesian approach
2016
We present a Bayesian approach to particle identification (PID) within the ALICE experiment. The aim is to more effectively combine the particle identification capabilities of its various detectors. After a brief explanation of the adopted methodology and formalism, the performance of the Bayesian PID approach for charged pions, kaons and protons in the central barrel of ALICE is studied. PID is performed via measurements of specific energy loss ($\mathrm{d}E/\mathrm{d}x$) and time-of-flight. PID efficiencies and misidentification probabilities are extracted and compared with Monte Carlo simulations using high-purity samples of identified particles in the decay channels ${\rm K}^0_S \righta…
Problemas multiplicativos relacionados con la división de fracciones : un estudio sobre su enseñanza y aprendizaje
2013
Los estudiantes tienen dificultades para asociar el enunciado de un problema multiplicativo con la operación que permite resolverlo; esta investigación identifica los tipos de problemas multiplicativos que los estudiantes reconocen como de división de fracciones. Mediante el análisis histórico-epistemológico de textos de enseñanza sobre tres épocas históricas y ocho períodos diferentes, se obtiene un listado de variables de enseñanza (algoritmos, sentidos de uso de fracción y de división de fracciones, representaciones, problemas), así como los valores de dichas variables. Se localizan en los textos consultados algunas reglas particulares y seis algoritmos generales, cuyo predominio ha vari…

A naive approach to compose aerial images in a mosaic fashion
2002
There is growing interest in multiple sequence image analysis to represent those data in a new landscape, for instance reconstruction of old films, mosaicing of images. This paper focuses attention on the mosaic problem; it introduces a naive method to link together images where a common part of the scene is present among two images. An application has been developed to test the method on aerial sequences of images. Given the long distance of aircraft from the scene, the method assumes images without distortions and without problems of prospective. Moreover, the application does not need any additional parameters coming from human experience and for this reason it can be thought of as a ful…
A rare case of acute idiopathic colocolic intussusception in an adult patient
2020
Abstract Adult intussusception is a rare condition that is frequently associated with malignancy and requires surgical approach. Symptoms are often non-specific and of subacute or chronic character. Therefore, computerized tomography (CT) scan is the most commonly used modality for identifying adult intussusception. A 51-year-old female presented with a 1-day history of increasing abdominal pain. Abdominal ultrasound and CT scan revealed intussusception. Intra-operatively, colocolic intussusception was present and laparoscopically reduced. A lead point was found neither intra-operatively nor in post-operative ileocolonoscopy and resection of involved bowel segments was not necessary.
Integrating the Real and Virtual World for Academic Language Education in Second Life
2013
This chapter focuses on a Second Language Acquisition (SLA) study conducted in virtual worlds that could help teachers in terms of knowledge about acquisition processes, in which technology is integration between formal and non formal education. The research comprises of two studies strongly focused on the development of Italian oral language proficiency. It was held within Second Life® (SL™)1 in order to explore the affordances of public spaces to enhance Intercultural Communicative Competence (ICC)2 and to stimulate the oral production through learner’s engagement. Since 2007, a new pilot project, Café Italia, was developed by Carmela Dell’Aria (aka Misy Ferraris) in Second Life®. Startin…
Evaluating the Effectiveness of Modelling-Oriented Workshops for Engineering Undergraduates in the Field of Thermally Activated Phenomena
2017
Two 20-h modelling-based workshops focused on the explanation of ther- mally activated phenomena were held at the University of Palermo, Italy, during the Academic Year 2014–2015. One of them was conducted by applying an inquiry-based approach, while the other, still based on laboratory and modelling activities, was not focused on inquiry. Seventy-two students belonging to the Undergraduate Program for Chemical Engineering attended the two workshops. The related content was focused on an à la Feynman unifying approach to thermally activated phenomena. Question- naires were administered to the students of both groups, before and post instruction. Responses were analysed using k-means cluster…
