A facially driven complete-mouth rehabilitation with ultrathin CAD-CAM composite resin veneers for a patient with severe tooth wear: A minimally inva…
2020
Abstract The development of technologies that include face scanning and dental software has improved workflows in dentistry. Digital files make it possible to create a 3-dimensional virtual image of the patient that helps the clinician plan treatment and make decisions, reducing uncertainty and improving communication. This report describes the complete-mouth rehabilitation of a patient with severe tooth wear. The treatment adopted a minimal intervention approach, applying adhesive veneers in areas where the tooth structure was affected and used a computer-aided design and computer-aided manufacturing (CAD-CAM) workflow to prepare nanoceramic composite resin materials with a high filler loa…
Il desiderio come luogo di testimonianza. A partire da alcuni versi di Paul Celan
2019
The author shows how the theme of eros in Paul Celan constitutes the place of a division of the subject despite to which the difficult search for unity is problematically entrusted. For this radicality, desire becomes the testimony of the impossibility to separate life from death which reflects intimately the condition of Jewish survivor for whom the continuity of life appears irreversibly broken.
Microstructural analysis (Voigt function method) of mullite in whiteware triaxial porcelains
2020
Triaxial porcelains were produced of two whiteware blends containing kaolin B (of “high-crystallinity” kaolinite) or halloysitic kaolin M (also with “low-crystallinity” kaolinite) in two different industrial firing cycles (fast or slow) with final temperatures 1270 °C, 1300 °C, 1320 °C and 1340 °C. The crystalline microstructure of mullite in all porcelain samples was studied by X-ray diffraction through analysing 110 and 001 reflections using the Voigt function method and by optical and electron microscopy. Mean crystallite sizes were determined independently for both 110 and 001 diffraction directions as principal semi-quantitative characteristics for all sixteen specimens. They illustrat…
Zirconia implant abutments: A review
2009
Objectives: An increasing aesthetic demand within developed populations conducted to the fabrication of metalfree restorations and to a wide use of ceramic materials, due to its excellent characteristics of biocompatibility and aesthetics. With the incessant increase of commercial labels involved in this technological advance, a review is imposed on ceramic abutments, specifically on zirconia. We made a search of articles of peer-reviewed Journals in PubMed/ Medline, crossing the terms ?Dental Abutments?, ?Dental Porcelain? and ?Zirconia?. The review was divided by subtopics: zirconia physical and mechanical properties, precision fit in the implant-abutment interface, zirconia abutments str…
Aproximación al proceder hermenéutico del TJUE: libertad de empresa, libre competencia y Constitución del Trabajo
2017
La primacía de los derechos fundamentales constituye uno de los logros normativos de la postguerra. En contraste, la conquista jurídica del Derecho de la Unión ha consistido en someter a los parlamentos estatales a la primacía de las libertades de mercado, incluso en detrimento de los llamados derechos humanos ¿clásicos¿. Las libertades comunitarias efectúan una concreción de la libertad de empresa en sus respectivos ámbitos materiales. Sin embargo, éstas incorporan un contenido diferenciado del atribuido al contenido esencial de la libertad de empresa reconocido en el nivel nacional. El proceso de mutación constitucional en el ámbito europeo se dirige así hacia una confluencia con el model…

Antinociceptive effects of an extract, fraction and an isolated compound of the stem bark of Maytenus rigida
2012
The antinociceptive activity of the Maytenus rigida Mart. (Celastraceae) ethanol extract and its ethyl acetate fraction as well as of (-)-4'-methylepigallocatechin (1), a previously isolated compound, was demonstrated in vivo. ED50 for 1 in the writhing test was 14.14 mg/kg. The acetic acid-induced writhing was inhibited by 98.4, 84.4, and 58.3%, respectively, when mice were treated with the ethanol extract, ethyl acetate fraction, and 1. In the hot plate test, mice pretreated with 1 showed significantly increased reaction times (60-89%). Oral administration of 1 significantly inhibited first and second phases of the formalin-induced pain (50 and 26.5%, respectively), whereas indomethacin i…
"La construction du personnage dans les derniers récits de Raffaele La Capria"
2018
C’est à la fin des années soixante-dix, au moment où d’anciens protagonistes des avant-gardes littéraires (comme Sollers en France ou Eco en Italie) renouent avec la fiction, que Raffaele La Capria, l’un des précurseurs dans la péninsule du roman expérimental, renonce définitivement au genre. Amore e Psiche, publié pour la première fois en 1973, fera l’objet de plusieurs remaniements sans que l’auteur en soit jamais satisfait. À partir des années quatre-vingt, La Capria ne publie plus que des...

Dimensión socio-laboral de las relaciones comerciales trasatlánticas: algunas lecciones del pasado.
2022
En la cumbre UE-EE.UU. del pasado 15 de junio de 2021, la Unión Europea y los Estados Unidos realizaron una declaración conjunta en la que anunciaron una asociación transatlántica renovada para la era posterior a la pandemia. De manera que en el momento en el que se refuerzan las negociaciones comerciales entre la UE y EE.UU. vale la pena analizar hasta dónde se llegó en las negociaciones del Acuerdo Transatlántico sobre Comercio e Inversión en el marco de la OMC, en particular en relación a los aspectos más controvertidos desde la perspectiva social. Lo que incluye un análisis comparado específicamente enfocado al tratamiento del desplazamiento de trabajadores en el AGCS y en la Directiva …
