Processing and properties of infrared transparent (oxy)sulfide ceramics
No full textInternational audience(Oxy)sulfide materials possess unique combination of physico-chemical properties (high thermal and chemical stability, large domain of transparency, low phonon energy….) making them ideal candidates for both active and passive optical applications. However, among them, only zinc sulphide (ZnS) is commercialized as infrared optics. Sintering polycrystalline ceramic materials to transparency is a very challenging task. Transparency of ceramics is indeed highly influenced by light scattering on residual pores, inclusions of secondary phases or impurities and, in the case of birefringent materials, light scattering by randomly oriented birefringent grains. Special attention should be paid, in particular, to the synthesis methods in order to satisfy powder purity and powder size requirements. For this reason, little research has succeeded in the quest for new infrared transmitting materials. This presentation addresses recent developments on the processing of (i) ZnS with improved hardness in comparison to commercial products (ii) CaLa2S4 and BaLa2S4 of cubic Th3P4-type and (iii) hexagonal La2O2S. The properties that have been investigated are primarily related to their application as infrared window materials, i.e. optical and mechanical. The presentation aims to understand the relationship between processing and subsequent microstructure of the ceramics and their optical and mechanical properties. References[1] C. Chlique, O.

La filosofía del derecho de Alexandre Kojève
No full textThis article is a presentation of Alexandre Kojève’s philosophy of law, exposed in his Esquisse d’une phénoménologie du droit (1981). Little attention has been paid to this work. So there is a gap that has to be filled with a critical reflection of its strengths. Among them, undoubtedly, we count the fact that Kojève is introducing a conception of international justice that casts a singular light on current debates about cosmopolitanism and globalization. According to this author, citizenship is the key element of the process of global expansion of the juridical sphere. In sum, Kojève’s philosophy is useful to reflect upon the contrast between the juridical and the political, which is the basis for all philosophy of law, in order to achieve world peace and international justice.Este artículo es una presentación de la filosofía del derecho de Alexandre Kojève contenida en su Esquisse d’une phénoménologie du droit (1981). La poca atención que dicha obra ha recibido es un vacío que debiera llenarse con una reflexión crítica de sus puntos fuertes. Entre ellos destaca una concepción de la justicia internacional que proyecta una luz muy singular sobre los actuales debates en torno a la globalización y el cosmopolitismo. A ojos de este autor, la ciudadanía es el elemento clave para aquilatar la expansión global de lo jurídico. En suma, Kojève aparece como un valioso referente en la labor de pensar la contraposición entre lo jurídico y lo político que está en la base de toda filosofía del derecho, con la aspiración al logro de la justicia internacional y la paz mundial en el horizonte
Reconfiguração do consensualismo contratual: as ações tituladas nominativas e os limites à transmissão
No full textPartimos da evolução histórica do consensualismo contratual salientando os
principais carateres que, nos diversos momentos históricos, se foram evidenciando.
Numa segunda etapa exploramos os fundamentos dogmáticos do modelo de
transmissão contratual assumido pelo legislador e a sua viabilidade no sistema
jurídico global, em particular, no direito dos valores mobiliários. Constatamos a
crescente necessidade na prática mercantil e inevitabilidade no sistema jurídico
global da admissibilidade da existência de contratos de compra e venda de natureza
meramente obrigacional. Num terceiro momento desenvolvemos os principais
aspetos do regime jurídico aplicável às ações tituladas nominativas fora do mercado
regulado, em particular, os principais limites à transmissão, enquanto instrumentos/barreiras ao consensualismo contratual.We start from the historical evolution of contractual consensualism emphasizing the
main aspects that, in different historical moments, were showing up. In a second
stage we explore the dogmatic foundations of the transmission model contractual
assumed by the legislator and its viability in the global legal system, in particular, in
securities law. We note the growing need in commercial practice and inevitability in
the global legal system the admissibility of the existence of contracts of sale purely
obligatory. In the third stage we develop the main aspects of the legal regime
applicable to nominative titled actions outside the regulated market, in particular,
the main limits to the transmission, as instruments / barriers to contractual
consensualism
“Era por Alexandre tod’esto demostrado”: ¿pruebas verídicas y pruebas engañosas en el Libro de Alexandre?
No full textEl Libro de Alexandre es un texto de s. XIII, que se escribió en la España medieval. En este escrito, el autor pretende demostrar que, en el Alexandre, algunas de las situaciones que se ponen a prueba son aceptadas, pero eso no significa que el macedonio gane la prueba. El articulo esta dividido en tres apartados. En el primero, el autor da cuenta de la historia textual de la obra y también dedica ciertas líneas al Estado de la cuestión del texto; mientras que, en la segunda parte, nos guía a conceptos etimológicos de los términos prueba, evidencia y demás. En el tercer apartado se centra en algunas pruebas expuestas en el Libro de Alexandre.The Libro de Alexandre is a literary work, written during the medieval Spain. In this paper, the author tries to demonstrate that, carefully reading the L.A, some of the situations that are set as proves are accepted, but it does not mean that Alexander can be a victor. This paper is divided in three sections: firstly, the author tells the textual history of the L.A and, then, tries to update the State of art: on the other hand, in the second part, the author offers meanings about terms as: prueba and evidencia. Finally, the author focuses on certain passages contained in the Libro de Alexandre that can be taken as failed proves
Mixing the Immiscible: Improvisation within Fixed-Media Composition
No full textThis paper will explore ways in which mastered improvisation practice, with the studio as an instrument, is a proposed avenue to bridge the historical dichotomy between what Ted Gioia describe as ‘the aesthetics of perfection’ and ‘the aesthetics of imperfection’. It is proposed as a way to re-embody fixed music, as experimented by the author through the composition of his last fixed-media work. This will be put in the context of a wider trend observed amongst the current emerging generation of composers interested in the aesthesics of the work, by opposition to the previous generations that placed the value of the work in its poietics. The vital and primal importance of practice outcome as practice-based research’s main document will also be advocated for, as these trends are happening in the laboratory of live music

La Clerecía de "Alexandre"
No full textEl artículo reflexiona sobre la educación que recibe Alexandre “El grande” a manos de su profesor Aristóteles, retratado en el “Libro de Alexandre”; a continuación analiza las disciplinas que compusieron dicho programa con el interés de proponer una interpretación de la lista de las siete artes liberales mencionadas. Este artículo ofrece una visión de las diferentes maneras en las que los textos reflejan la “clerecía” del protagonista así como de otros personajes, incluyendo el anónimo autor de los mismos. Cualquiera que se dedique a las mencionadas artes liberales será glorificado y Alexandre se presenta él mismo como modelo ideal de un príncipe en quien la nobleza y al inteligencia van unidas, una defensa clara de la “clerecía” como fuente fundamental de toda excelencia. This article deals with the education imparted on Alexander the Great by Aristotles, as portrayed in the “Libro de Alexandre”, analyzes the disciplines and proposes an interpretation of the list of the seven liberal arts mentioned therein. This article also offers an encompassing view of the different ways in which the text reflects the “clerecía2 of the protagonist as well as that of the other characters, including the anonymous author himself. Anyone who dedicates him or herself to the aforementioned liberal arts is thereby glorified, and Alexander presents himself as the ideal model of a prince in whom nobility and cleverness are joined, in a clear defense of the “clerecía” as the fundamental source of all excellence
Modélisation de l'optimisation du pilotage des performances des bovins et de la qualité de leur viande
No full textThe French beef industry, which is facing numerous challenges that threaten its sustainability in the territories, wishes to revive itself by proposing an increase in the quality of its products. In this thesis, we have developed a decision support tool to assist the stakeholders in the sector (processors, distributors, etc.) in designing new demarcations.This tool is based on an innovative approach to deal with the antagonisms between cattle performance and meat quality, and thus enables the decision-maker to choose the trade-off that best meets his expectations.This trade-off search has been modeled as a multi-objective optimization problem that is solved by defining a partial order between the vectors of the objective space: the Pareto dominance.Lacking analytical objective functions, surrogate models have been estimated from observations of the objectives for given production parameters. To ensure to the decision maker that the promised optimal value will be reached at a controlled occurrence, a version of the Value-at-Risk adapted to a multi-objective problem was developed.The numerous data needed to estimate the surrogate models were provided by European cattle experiments. These had studied at least one aspect of the quality of meat from the Longissimus thoracis muscle: sensory quality or nutritional quality, via the fatty acid profile of the muscle.An open access web interface was designed with the R Shiny package in order to distribute the decision support tool. Finally, specifications responding to issues that we identified as relevant were generated using this interface in order to discuss the potential applications of the tool.La filière viande bovine française, qui est confrontée à de nombreux défis menaçant sa pérennité au sein des territoires, souhaite se relancer en proposant une montée en gamme de ses produits. Dans cette thèse, nous avons donc développé un outil d'aide à la décision pour accompagner les acteurs de la filière (transformateurs, distributeurs, etc.) dans la conception de nouvelles démarcations.Cet outil s'appuie sur une approche innovante pour gérer les antagonismes entre performance des bovins et la qualité de leur viande, et permet ainsi au décideur de choisir le compromis qui correspond le mieux à ses attentes.Cette recherche de compromis a été modélisée sous la forme d'un problème d'optimisation multi-objectifs qui est résolu grâce à la définition d'un ordre partiel entre les vecteurs de l'espace des objectifs : la dominance de Pareto.En l’absence de fonctions objectifs analytiques, des modèles de substitution ont été estimés à partir d’observations des objectifs pour des paramètres de production donnés. Pour assurer au décideur que la valeur optimale promise se réalisera à une occurrence contrôlée, une version de la Value-at-Risk adaptée à un problème multi-objectifs a été développée.Les nombreuses données nécessaires pour estimer les modèles de substitution sont issues d’expérimentations européennes sur les bovins. Celles-ci avaient étudié au minimum un aspect de la qualité de la viande issue du muscle Longissimus thoracis : la qualité sensorielle ou la qualité nutritionnelle, via le profil en acide gras du muscle.Une interface web libre d'accès a été conçue avec le package R Shiny afin de diffuser l’outil d'aide à la décision. Des cahiers des charges répondant à des enjeux que nous avons identifiés comme pertinents ont enfin été générés grâce à cette interface afin d’alimenter la discussion sur les potentielles applications de l’outil
