The granular flow behavior of carbon nanotubes produced by the CCVD method in a laboratory continuous inclined rotary reactor and of a catalyst was experimentally studied using a rotating drum. The dynamic angle of repose of the bulk solid and the standard variation of the solid bed surface were determined as a function of rotational speed of the rotating drum and for several filling percentages of the drum. Whatever the carbon nanotube production conditions, the dynamic angle of repose and the standard variation of the solid bed depended only on the filling percentage of the drum. Results were very interesting for practical application to carbon nanotube production in an industrial continuous inclined rotary reactor, because the granular flow behavior was the same during the reaction throughout the length of the reactor and depended only on the reactor filling. A bed behavior diagram based on the drum rotational speed and on the drum filling percentage was also constructed experimentally. The flow behavior of the solid during carbon nanotube production was on the boundary between the slumping and the rolling modes, leading to a good mixing of gas and solid during the reaction and to an improvement of the mass and heat transfer in the bed.

Modified laponites and synthetic saponites are used as precursors for the preparation of poly(epsilon-caprolactone) (PCL)/clay nanocomposites. The structure and dynamics of species intercalated in the modified clays and the corresponding nanocomposites are characterized by X-ray diffraction and magic-angle spinning NMR. The influence of the headgroup, the hydrocarbon chain length, and the loading of the surfactant on the nanocomposite formation are discussed. The yield of PCL intercalation is related to the probability of direct polymer-clay interactions and to the size of the clay platelets. Relaxation times in the laboratory and rotating frames that allow characterization of fast and slow molecular dynamics in these systems are discussed, showing a motional heterogeneity of the intercalated species.

En la Terminología wüsteriana ‘clásica’ el “término ideal” es monosémico, o monorreferencial, biunívoco, exento de connotaciones, normalizado, prescriptivo en su empleo, productivo y motivado. Hemos aplicado al corpus jurídico objeto de nuestro estudio – la Responsabilidad civil extracontractual - el filtro de lectura de la terminología clásica. El resultado observado es que, a cada una de estas características corresponden ejemplos observados en la nomenclatura estudiada que desmienten la adecuación a dicha nomenclatura al ideal terminológico. En efecto : - Al ideal de monosemia o monorreferencialidad, que requiere una determinación inequívoca de las nociones, una definición estricta de los términos y que cada uno de éstos designe una noción única y sin connotaciones, se oponen los siguientes rasgos observados : la existencia de nociones de imposible definición o de definiciones de contenido variable; la incertidumbre de la propiedad técnica de la definición de los términos; la alta proporción de términos que son homónimos de palabras de la lengua común; la presencia de connotaciones indeseadas; las frecuentes polisemia y homonimia que ostentan no pocos términos; - Al ideal de biunivocidad se opone un fenómeno de sinonimia abundante; - Al ideal de normalización de los términos de las Lsp, lo mismo que al carácter ideal de ser prescriptivos en su empleo, se opone, no sólo la existencia de lexicalización incompleta, sino también la de nociones sin denominaciones. También se verifica ausencia de unanimidad entre autores sobre el uso de los términos (definiciones y denominaciones). - El ser productivos los términos plantea el problema de derivaciones de coherencia perdida. - Hasta aquí, pues, el análisis no señala más que ‘defectos’ que ostenta la nomenclatura terminológica estudiada. Sin embargo, al abordar el último tema de la motivación de los términos, la investigación, de pronto, debe desistir de toda idea de 'defecto' y reconocer más bien a los juristas una singular y constante preocupación por la justeza y afinamiento de las denominaciones. Lo cual no sólo es en sí un esfuerzo poco común entre los usuarios de la lengua, inclusive de especialidad, sino que, incluso justifica los supuestos ‘defectos’ anteriormente observados, en realidad suscitados por el esfuerzo mismo de perfeccionamiento de las denominaciones. Ante semejante análisis, nuestra conclusión ya no puede someterse al ideal wüsteriano, pronto a imponer una ‘normalización’ de los defectos observados, los cuales, correctamente analizados, no son sino las consecuencias provisionalmente negativas de un ideal superior. Antes bien, nos parece más atinado distanciarnos de Wüster, poniendo en tela de juicio los requisitos mismos del “termino ideal” de su doctrina terminológica. En conclusión, corregimos el idealismo wüsteriano, asignando su justo lugar y papel a sendos rasgos nocionales y lenguajeros de las LFE. [less ▲]

Considering their sociocultural and economic impact, sport events represent a pertinent centre of interest for sport management research. Considering their frequent occurrence and importance to the survival of many associations such as sport clubs, schools, youth or neighbourhood committees, mass sport events could receive more attention than they actually do. In this paper attention was focused on participants and spectators attending the following five mass sport events organised in Wallonia, the French speaking part of Belgium. [less ▲]

In late modernity societies where pursuit of career in an unstable and rapidly changing occupational structure is so difficult, motivation fueling vocational constructing behaviors appears to be a prerequisite of success. However, motivational processes are only half of the story. In order to overcome internal or external obstacles to a confident and peaceful reflection on their career development, individuals need more than ever to bring into play volition, that is, the capacity to regulate psychological functions such as cognition, motivation, and emotion in order to determine which motivational tendencies are implemented, when, and how. The first aim of this contribution is to present some aspects of this overarching concept originating in experimental and social psychology, and recently also considered by cognitive neurosciences. Taking the psychology of action control as a lens of analysis, the chapter outlines (1) action versus state orientation affect–regulatory competences embedded in Personality Systems Interactions theory (Kuhl, 2000a, 2000b), which proposes an explanation of functional relationships between cognitive and affective systems underlying action; (2) implementation intentions (Gollwitzer, 1993, 1999), that is, a kind of specific plans which differs from goal intentions and may be activated in the postdecisional pre-action phase of the Rubicon Model of Action Phases. As a second aim of the chapter, some applications of these volitional constructs to the vocational domain, until now largely or completely unexplored, are proposed in order to suggest how leading theories in the field can enrich concrete practices to help students and clients, faced to an unsecured world, volitionally construct the future of their career.

Nombreux sont ceux qui attribuent une importance capitale aux motivations à la participation des jeunes au sport. En effet, les modalités de pratique et la qualité des expériences vécues dans le domaine des activités physiques et sportives exerceraient de profonds effets dans la perspective d'un style de vie actif et sain à l'âge adulte. Cette croyance, bien établie chez les éducateurs physiques et les partisans du sport, doit néanmoins être prise avec beaucoup de prudence lorsque l'on considère les résultats des études longitudinales. ...

Firstly, in this paper the historical analysis of volition as a specific construct in front of motivation and conation is developed. From the middle of the eighties volition is focused in empirical literature as a central concept in goal-directed learning behaviours, especially when goals are difficult to reach. Secondly, limits of motivation (values, expectations) to explain reaching complex learning goals which imply overcoming internal or external obstacles are heightened and volition (action control strategies and implementation intentions) is proved to basically contribute to initiate goal-directed actions and bring them to a successful conclusion.

Au cours des trois dernières années, plusieurs révisions de la Constitution ont modifié ou permis l’extension des compétences du Conseil d’État. C’est ainsi que, par l’effet combiné des nouveaux articles 144, alinéa 2, de la Constitution et 11bis des lois coordonnées du 12 juillet 1973, il peut à présent connaître des demandes « d’indemnité réparatrice » pour les dommages causés par les actes dont il a constaté l’illégalité. La compétence du juge ordinaire reste cependant ouverte. Mais electa una via… La question du choix du juge se pose donc une nouvelle fois dans le contentieux administratif belge. Ici sous l’angle de l’opportunité. Cette question continue aussi de se poser dans sa formulation plus classique : jusqu’où s’étend la compétence du Conseil d’État, quand cesse-t-il d’être compétent pour connaître des demandes d’annulation des actes administratifs portées devant lui ? La loi du 20 janvier 2014 a modifié sous bien des aspects la compétence du Conseil d’État. Notons la réforme du référé administratif, la reconnaissance du contrôle de l’intérêt au moyen, l’indemnité de procédure ou l’allégement de la preuve du mandat ad litem de l’avocat ainsi que le perfectionnement ou l’introduction d’instruments destinés à étendre les moyens d’action du Conseil d’État et à sortir de la logique binaire annulation/rejet. Plusieurs aspects de cette réforme ont déjà été soumis au contrôle de la Cour constitutionnelle, tandis que la jurisprudence commence à se développer. Enfin, le moyen pris de la violation de la loi du 29 juillet 1991 semble empiriquement le plus fréquent dans les requêtes. La motivation formelle des actes administratifs constitue un tel enjeu de droit matériel et contentieux qu’elle devait une nouvelle fois retenir l’attention. Un ouvrage de la CUP consacré à ces sujets s’imposait. [less ▲]

Students’ motivation is a major concern of physical education teachers as well as it interest the others educators. Understanding of that complex variable increased during the last two decades. In the physical education domain, many studies were focused on isolated variables related to motivation and on their relationship with pupils’ behaviours. More recently, qualitative researches were conducted to enter in the class specificity and to integrate the complexity and diversity of the variables that influence students’ motivations. Combining questionnaires interviews and observation, some researchers have confirmed that student’s motivation depends on a package of dispositional as well as individual and collective situational factors. They pointed out also the determining role of the teacher in the development of a motivated class climate. This paper will describe a couple of qualitative studies designed to analyse students’ motivation and will underline their contribution in the understanding of the phenomena related to the development of motivation by students. Moreover, as teachers need research directly focused to their concerns, we must now provide them more support helping them to apply research data. The action research design is proposed as an appropriate approach in that way. The description of a pilot action research focused on the improvement of the students’ motivation in a secondary school level girls class will also proposed. The main results should provide the starting point of a reflective process about the strategies that teachers could plan on the gym. As it has been underlined above, the goal of the paper was to share useful information with practitioners and researchers and to encourage them to involve themselves in personal research on students’ motivation.
