Durcissement aux radiations de fibres optiques dopées terres rares et d'amplificateurs 'a fibres optiques
2011
National audience; Cette étude vise à comprendre les effets d'une irradiation Ȗ sur les propriétés optiques et structurales des fibres dopées aux Terres Rares en vue de leur utilisation dans des amplificateurs à fibre réalisés pour des applications spatiales. L'enjeu majeur de durcissement de ces composants est abordé via des techniques telles que le chargement en hydrogène et/ou le co-dopage au Cérium du cœur des fibres optiques. L'identification des centres responsables de l'atténuation induite par irradiation et la compréhension des mécanismes de dégradation mis en jeu sont des étapes indispensables au développement de ces fibres.
Performance Dissimilarities in European Union Manufacturing: The Effect of Ownership and Technological Intensity
2021
Our paper addresses the relevance of a set of continuous and categorical variables that describe industry characteristics to differences in performance between foreign versus locally owned companies in industries with dissimilar levels of technological intensity. Including data on manufacturing sector performance from 20 European Union member countries and covering the 2009–2016 period, we used the random forests methodology to identify the best predictors of EU manufacturing industries’ a priori classification based on two main attributes: ownership (foreign versus local) and technological intensity. We found that EU foreign-owned businesses dominate locally owned ones in terms of size, wh…
Crystal field and magnetism with Wannier functions: Rare-earth doped aluminum garnets
2015
Using the recently developed method we calculate the crystal field parameters in yttrium and lutetium aluminum garnets doped with seven trivalent Kramers rare-earth ions. We then insert calculated parameters into the atomic-like Hamiltonian taking into account the electron-electron, spin-orbit and Zeeman interactions and determine the multiplet splitting by the crystal field as well as magnetic $\hat{g}$ tensors. We compare calculated results with available experimental data.
Role of the N-*(1535) in the J/psi -> pp and J/psi -> p(+)Lambda reactions
2009
We study the J/psi -> p eta p and J/psi -> pK(+)Lambda reactions with a unitary chiral approach. We find that the unitary chiral approach, which generates the N-*(1535) dynamically, can describe the data reasonably well, particularly the ratio of the integrated cross sections. This study provides further support for the unitary chiral description of the N-*(1535). We also discuss some subtle differences between the coupling constants determined from the unitary chiral approach and those determined from phenomenological studies

Development of silent reading fluency and reading comprehension across grades 1 to 9 : unidirectional or bidirectional effects between the two skills?
2022
Purpose This study examines the developmental interplay between silent reading fluency and reading comprehension from Grade 1 to Grade 9 (age 7 to 15) in a large Finnish sample (N = 2,518). Of particular interest was whether the associations are bidirectional or unidirectional. Methods Children’s silent reading fluency and reading comprehension skills were assessed using group-administered tests, at seven time points, in Grades 1, 2, 3, 4, 6, 7, and 9. A random intercept cross-lagged panel model with latent factors was used to identify between- and within-person associations between silent reading fluency and reading comprehension. The use of latent factors allowed for the controlling of me…
Influence of brand image of a sports event on the recommendation of its participants
2020
The aim of this research is to test the psychometric properties and relationships of a model where, from brand congruence of a sport event, trust and commitment to it can be generated, influencing future behavior of participants and resulting in a higher recommendation also called Word of Mouth (hereinafter WOM). A quantitative approach has been carried out by means of a validated questionnaire with Likert-type responses, and data were analyzed with the EQS 6.4 software. The findings indicated that the model is adequate, and also confirm that from congruence, we can explain, at a theoretical level, 45% of trust, and in the same way, from the congruence and trust, we can explain 67% of the c…
La desheredación del menor de edad
2021
This work aims to answer the eternal question of the disinheritance of the child under legal age. To this end, we will approach the institute of disinheritance, its foundation and its jurisprudential evolution. We will also address the capacity and responsibility of the child under legal age and the emancipated minor. Subsequently, we will carry out the study of the disinheritance of the child under legal age, subject to the whim of the specific disinherited causes, since each of the causes provided for in art. 853 Spanish Civil Code are endowed with their own idiosyncrasy, being very complicated, if not impossible, to deal with the subject of this work apart from the vicissitudes that can …
Évolution historique des critères de reconnaissance du statut d’État à des entités contestées
2018
The historical evolution of the criteria for recognition is only a reflection of the historical evolution of the functions that the act of recognition has fulfilled, and is fulfilling today in international law. Among the various possibilities, this contribution identifies at least 5 functions historically fulfilled by the act of recognition: co-optation, recognition, promotion, sanction, validation. Thus, the idea developed is that by virtue of the function fulfilled, the role played by different types of criteria of legitimacy, legality, effectiveness is destined to change.
Acute hormonal and muscular responses and recovery : chronic adaptations to single session combined strength and endurance training with regard to or…
2012
Combining both strength (S) and endurance (E) exercise loadings into a single training session can be considered to be of interest e.g. for time management purposes. However, the first loading in a combined session tends to produce notable acute fatigue responses, which can lead to the second loading being performed in a compromised state. Research on fatigue and recovery from a combined session with different loading orders is currently scarce, with even less attention given to the acute responses. Thus, this study investigated the long-term adaptations in the acute responses of a combined strength and endurance loading and whether or not there is an order effect. A total of 29 male subjec…
