Comparison of the accuracy of intraoral digital impression system and conventional impression techniques for multiple implants in the full-arch edent…
2020
Background Several impression techniques, especially in combination with computer-aided design and computer-aided manufacturing (CAD/CAM), are used in increasing the accuracy of dental implantology and decreasing patient discomfort. The study was designed to examine the accuracy of the digital impression (DI) of multiple implants with an intraoral scanner (IOS) and compared with that of a conventional impression (CI). Material and methods Four dental implants were placed in teeth area #33, #36, #43 and 46# of the mandibular full-arch model. The implanted model was replicated by IOS and CI after fitting of scannable abutments over the implant screws. Then, a small hole was made on the scan r…
LA COPERTURA IN FERRO DEL POLITEAMA GARIBALDI. UNA INNOVATIVA SPERIMENTAZIONE NELLA PALERMO DEL XIX SECOLO
2015
The roofing of the nineteenth Politeama Garibaldi in Palermo creates to the designer, Giuseppe Damiani Almeyda, technical and architectural difficulties: in fact, if the scene roofing has been resolved applying established schemes, for the roofing of the stalls area, made years later, an efficient connection with the existing roofing and the external walls was manifested. The goal of this study is the knowledge of the iron structure, the production and processing techniques adopted for the realization of the roofing, also aimed to the recognition of the inspiring structural models, the connecting systems, the state of preservation. Through the analysis of the used shapes and techniques, the…
Pascal and the question of technique
2017
The purpose of the essay is to discuss some implications of Pascal's philosophical discourse on the problem of technique and his rejections of Cartesian metaphysics. Author shows a singular perspective about technic in Blaise Pascal's philosophy. This perspective marks the difference with Descartes, linking technic to hearth and memory.
Ferroelectricity and piezoelectricity in soft biological tissue: Porcine aortic walls revisited
2017
Recently reported piezoresponse force microscopy (PFM) measurements have proposed that porcine aortic walls are ferroelectric. This finding may have great implications for understanding biophysical properties of cardiovascular diseases such as arteriosclerosis. However, the complex anatomical structure of the aortic wall with different extracellular matrices appears unlikely to be ferroelectric. The reason is that a prerequisite for ferroelectricity, which is the spontaneous switching of the polarization, is a polar crystal structure of the material. Although the PFM measurements were performed locally, the phase-voltage hysteresis loops could be reproduced at different positions on the tis…
Bis(arylimidazole) Iridium Picolinate Emitters and Preferential Dipole Orientation in Films
2018
The straightforward synthesis and photophysical properties of a new series of heteroleptic iridium(III) bis(2-arylimidazole) picolinate complexes are reported. Each complex has been characterized by nuclear magnetic resonance, UV-vis, cyclic voltammetry, and photoluminescent angle dependency, and the emissive properties of each are described. The preferred orientation of transition dipoles in emitter/host thin films indicated more preferred orientation than homoleptic complex Ir(ppy)3.
An empirically grounded agent based simulator for the air traffic management in the SESAR scenario
2017
In this paper we present a simulator allowing to perform policy experiments relative to the air traffic management. Different SESAR solutions can be implemented in the model to see the reaction of the different stakeholders as well as other relevant metrics (delay, safety, etc). The model describes both the strategic phase associated to the planning of the flight trajectories and the tactical modifications occurring in the en-route phase. An implementation of the model is available as an open-source software and is freely accessible by any user. More specifically, different procedures related to business trajectories and free-routing are tested and we illustrate the capabilities of the mode…
Synthèse sur la détection des produits issus des nouvelles technologies génomiques (NGT) appliquées aux plantes. Paris, Paris, le 26 novembre 2021
2021
Synthèse sur la détection des produits issus des nouvelles technologies génomiques (NGT) appliquées aux plantesLa question du statut réglementaire des NGT (New Genomic Techniques), qui ont été définies comme techniques de modification du génome « apparues » depuis 2001 , est actuellement débattue en Europe. Ces techniques n’existaient pas, ou étaient peu développées lors de l’adoption des directives et règlements européens qui encadrent actuellement les organismes génétiquement modifiés (OGM). A l’époque le législateur européen avait choisi de réglementer les techniques de transgénèse et d’exempter les méthodes de mutagénèse notamment sur la base d’une expérience d’usage n’ayant révélé aucu…
A bargaining model of Farrell inefficiency
1998
Abstract An enormous number of empirical papers have estimated technical efficiency, the distance of firms inside a frontier, following the model of Farrell (Farrell, 1957. The measurement of productive efficiency. Journal of the Royal Statistical Society Series A 120 (3), 253–290). We propose a theory that explains the distance these empirical papers seek to measure. The theory is based on the idea that workers can bargain low `effort' (high crew sizes etc.) if they and the firm have some monopoly power. We provide simple theoretical expressions for the empirical measures of technical and allocative efficiency and compare them to those in the statistical literature. We also consider the re…
Pesquisa de enfermagem e modelos de citação bibliográfica
2009
Esta investigación se centra en el análisis de la forma de publicar de las revistas de enfermería. Se analizan básicamente dos modelos, el modelo Vancouver, promovido por el Comité Internacional de Editores de Revistas Médicas, y el modelo APA, de la Asociación Norteamericana de Psicología. Se discuten sus ventajas e inconvenientes. A la vista de cómo se publica en la actualidad y de cómo se juzga la investigación, se propone que las revistas de enfermería adopten su propio modelo, independientemente de cómo publican los profesionales de la medicina. Esta pesquisa concentra-se na análise de como os jornais de enfermagem publicam os seus artigos. Basicamente, dois modelos são analisados, o V…
Formations of Monoids, Congruences, and Formal Languages
2015
The main goal in this paper is to use a dual equivalence in automata theory started in [25] and developed in [3] to prove a general version of the Eilenberg-type theorem presented in [4]. Our principal results confirm the existence of a bijective correspondence between three concepts; formations of monoids, formations of languages and formations of congruences. The result does not require finiteness on monoids, nor regularity on languages nor finite index conditions on congruences. We relate our work to other results in the field and we include applications to non-r-disjunctive languages, Reiterman s equational description of pseudovarieties and varieties of monoids.
