Destination image and tourism intermediation. A possible interdisciplinary approach
2009
Estudio observacional prospectivo de valoración perioperatoria ecográfica del diafragma (D-POCUS) para la detección del bloqueo frénico y predicción …
2023
El músculo diafragma es el principal musculo que interviene en la ventilación, siendo responsable de alrededor del 80% del trabajo ventilatorio en condiciones normales. Cuando realizamos una anestesia del plexo braquial por encima de la clavícula, la proximidad del nervio frénico provoca un bloqueo de forma frecuente, y este hecho conlleva una disfunción hemidiafragmática en grado variable. Sin embargo pocos pacientes desarrollan complicaciones pulmonares postoperatorias. Se ha prestado poca atención al hemidiafragma contralateral como parte de la función diafragmática global. Conocer con exactitud el comportamiento de ambos diafragmas (en especial el contralateral al bloqueo) es clave para…
Measuring nuclear reaction cross sections to extract information on neutrinoless double beta decay
2017
Neutrinoless double beta decay (0v\b{eta}\b{eta}) is considered the best potential resource to access the absolute neutrino mass scale. Moreover, if observed, it will signal that neutrinos are their own anti-particles (Majorana particles). Presently, this physics case is one of the most important research "beyond Standard Model" and might guide the way towards a Grand Unified Theory of fundamental interactions. Since the 0v\b{eta}\b{eta} decay process involves nuclei, its analysis necessarily implies nuclear structure issues. In the NURE project, supported by a Starting Grant of the European Research Council (ERC), nuclear reactions of double charge-exchange (DCE) are used as a tool to extr…
Statistical properties of general Markov dynamical sources: applications to information theory
2004
In \textitDynamical sources in information theory: fundamental intervals and word prefixes, B. Vallée studies statistical properties of words generated by dynamical sources. This is done using generalized Ruelle operators. The aim of this article is to generalize sources for which the results hold. First, we avoid the use of Grotendieck theory and Fredholm determinants, this allows dynamical sources that cannot be extended to a complex disk or that are not analytic. Second, we consider Markov sources: the language generated by the source over an alphabet \textbfM is not necessarily \textbfM^*.
Earth resistance measurements in urban contexts: Problems and possible solutions
2017
Both EN 50522 and IEEE Std. 81 propose the Fall of Potential Method (FPM) to carry out the measurement of the resistance to earth of an Earthing System (ES). However, in urban areas, the recommended distances between the ES and auxiliary electrodes are not easy to respect, due to the presence of buildings and tarmac. Moreover, unknown buried metallic parts, as well as the interconnection among the ESs made by the Distributor System Operator, could modify the earth potential profile of the area, affecting the measurement results. In this paper, the issues that could affect the measurement result if FPM is used in an urban context are presented. A parametric analysis, carried out with Comsol …
Il piano economico finanziario nelle concessioni di servizi
2021
The motivational system contained in the sentence of the Council of State of 13 October 2020, n. 6168 suggests reflecting on the function performed by the economic and financial plan in the matter of service concession contract as well as on its possible qualification as an integral element of the economic offer presented by the economic operator
Gli operatori economici nel labirinto dei gravi illeciti professionali e il periodo triennale di esclusione dalla gara dall’accertamento definitivo
2019
In the presence of a difficult system, such as that of serious professional offences, art. 80, paragraph 5, lett. c), Legislative Decree no. 50 of 2016, this work aims, first of all, to identify possible solutions suitable for avoiding choices of exclusion from the tender, potentially arbitrary, by the station contractor and to ensure a tender procedure based on compliance with the principle of certainty of law and on the constitutional principles referred to in Articles 3, 41 and 117, paragraph 2 lett. e), Constitution. We then focus on the issue of the temporal relevance of serious professional offences, such as significant deficiencies in the execution of a previous procurement contract,…
Regularization Preserving Localization of Close Edges
2007
International audience; In this letter, we address the problem of the influence of neighbor edges and their effect on the edge delocalization while extracting a neighbor contour by a derivative approach. The properties to be fulfilled by the regularization operators to minimize or suppress this side effect are deduced, and the best detectors are pointed out. The study is carried out in 1-D for discrete signal. We show that among the derivative filters, one of them can correctly detect our model edges without being influenced by a neighboring transition, whatever their separation distance is and their respective amplitude is. A model of contour and close transitions is presented and used through…
Efectos del entrenamiento sensorimotor previo a la cirugía de artroplastia total en sujetos con osteoartritis de rodilla
2020
Introducción: El entrenamiento de fuerza y el sensorimotor son dos intervenciones comúnmente empeladas en sujetos con osteoartritis (OA) de rodilla. Sin embargo, una revisión sistemática de la literatura implementada como parte de este trabajo de tesis doctoral, reveló que la evidencia - especialmente en lo referente al entrenamiento sensorimotor - cuando se aplican en el periodo preoperatorio a la artroplastia total de rodilla (ATR), fue inconcluyente y no permitió extraer conclusiones sólidas sobre su efectividad en el postoperatorio temprano y tras un año de seguimiento. Objetivos: Estudiar los efectos derivados de implementar una intervención experimental preoperatoria, que combine el e…
