Effect of thermocycling with or without 1 year of water storage on retentive strengths of luting cements for zirconia crowns
2015
Abstract Statement of problem Bond stability between zirconia crowns and luting cement and between cement and dentin is a main concern; however, only limited evidence is available as to its longevity. Purpose The purpose of this in vitro study was to measure the retentive strengths of 7 self-adhesive cements (RelyX Unicem Aplicap, RelyX Unicem Clicker, RelyX Unicem 2 Automix, iCEM, Maxcem Elite, Bifix SE, SpeedCem), 2 adhesive cements with self-etch primers (Panavia 21, SEcure), 1 glass ionomer cement (Ketac Cem), 1 resin-modified glass ionomer cement (Meron Plus), and 1 zinc phosphate cement for luting zirconia crowns (LAVA) to extracted teeth after thermocycling with or without 1 year of …
Les déplacements des Lédoniens
1996
L a mise en service d' une liaison routière rapide ou d' une ligne TGV est susceptible de transformer la géographie des déplacements et, par là même, de modifier l' organisation spatiale d' une région dans la mesure où elle conduit à l'émergence de nouvelles pratiques.
EFFETS: expérimentation d'un outil d'aide à la décision, estimation de l’impact du télétravail sur les déplacements et les niveaux d’émission …

Gender differences in children escorting practices among dual-earners families in the Paris Region
2014
WIiT Paris 2014 : Women's Issues in Transportation - 5ème Conférence Internationale sur les Femmes et le Transport - Construire les ponts, PARIS , FRANCE, 14-/04/2014 - 16/04/2014; The present article looks to pinpoint explanatory factors for the sharing of escorting of children in dual-earner families. It proposes a detailed analysis of inequalities and interactions in dual-earner families when it comes to escorting children by taking into account the characteristics of trips to and from school for children, the characteristics of the parents' occupations, and the characteristics of the household. Compared with earlier research, the model considers more detailed data about the escorts' job…

Manufacturing and characterization of Al matrix composites with nano reinforcements via cold spraying
2019
This study aims at developing new routes for manufacturing Al matrix composites (AMCs) strengthened with nano reinforcements by solid-state cold spraying (CS) process. Three different AMCs including CNTs/Al, TiB2/AlSi10Mg and TiB2/7075Al were successfully fabricated by CS of the composite powders prepared using different approaches. The microstructure evolution of as-sprayed composite samples was investigated by means of different characterization methods like X-ray diffraction (XRD), scanning (SEM) and transmission electron microscopy (TEM) and electron backscatter diffraction (SEM/EBSD). The adhesion strength, tribological behaviour, corrosion properties as well as the mechanical performa…
Determining the effects of Eugenol on the bond strength of resin-based restorative materials to dentin : a meta-analysis of the literature
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/2076-3417/10/3/1070/htm Este artículo pertenece al número especial " Permanent and long-term biodegradable biomaterials". The aim of this study was to determine whether the residual presence of eugenol in coronal dentin may compromise the bond strength of resin-based restorative materials. A search was performed on MEDLINE/Pubmed, Scopus, and by hand search for relevant papers. No restriction was applied for language and publication date. The studies selected for analysis tested specimens with reduced size (micro-shear bond strength ( SBS) and micro-tensile bond strength ( TBS)) of adhesive systems and resin-bas…
Performing arts and mediation technology in the period of lockdown
2021
Advancements in digital technologies have become novel ways to enrich communication, expression, and transmission of arts knowledge. Technology is increasingly implemented in the performance space, as a source of inspiration for artists. Especially in this period of lockdown, mediation technology has turned out to be an essential tool for different aspects of social life, as in performing arts. With venues, schools and artistic activities closed, performers, students and spectators have been obliged to keep connecting in remote conditions. This article wants to retrace the aesthetic impact of mediation technology in performing arts during this period of lockdown by focusing on the aspects t…
In vitro enterococcus faecalis biofilm formation on five adhesive systems
2011
Objective: To determine the E. faecalis biofilm formation on the surface of five adhesive systems (AS) and its relationship with roughness. Study Design: The formation of E. faecalis biofilms was tested on the surface of four dual-cure AS: AdheSE DC, Clearfil DC Bond, Futurabond DC and Excite DSC and one light-cure antimicrobial AS, Clearfil Protect Bond, after 24 hours of incubation, using the MBEC high-throughput device. Results: E. faecalis biofilms grew on all the adhesives. The least growth of biofilm was on Excite DSC, Clearfil Protect Bond, and the control. Futurabond DC resulted in the greatest roughness and biofilm amount. There was a close relationship between the quantity of biof…
La mer et le silence
2013
Au début de la décennie 1890, le bruissement du monde pour Marey, s’est soudainement assourdi, émoussé, comme étouffé. Marey vient d’avoir soixante ans. Retrouver ses confrères parisiens lui devient plus pesant. Loin derrière lui maintenant, le bruit rythmé des chevaux au galop dont Marey déchiffrait chaque appui au sol dans des battues à trois ou quatre temps… Oublier aussi les cris des goélands au-dessus du Posillipo. Marey délaisse la rumeur du monde ou du moins y prête moins d’attention. Il s’adonne désormais à l’analyse de déplacements silencieux d’animaux marins quelquefois minuscules.
