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…

Fonctionnalisation de surfaces métalliques par des couches minces d'oxynitrures de titane obtenues par irradiation laser sous atmosphère contrôlée et…

2013

The technological advances in areas such as automotive and aerospace industries require materials capable of withstanding demanding conditions. Surface treatments are effective tools to improve the surface properties of materials while preserving their bulk properties. Besides many conventional processes, laser treatments are efficient methods for hardening and increasing the durability of materials. This work is focused on the growth of titanium oxynitride surface layers by laser irradiation of pure titanium plates with nanosecond pulsed sources. The influence of the laser treatment conditions on the composition and the structure of these surface layers was studied. In particular, for lase…

Souffrance, jugement moral et « société addictogène » : les registres de sens du traitement de la dépendance

2019

Cet article explore la teneur de l’évaluation morale dans les modes de traitement du « trouble addictologique » en s’intéressant aux trajectoires des personnes en prise avec des produits psychoactifs inscrites dans une démarche d’arrêt ou de diminution des consommations d’alcool ou des drogues illicites. En suivant ces trajectoires de sortie, j’ai pu questionner leur passage dans deux entités de traitement, les Centres de Soin, d’Accompagnement et de Prévention en Addictologie (CSAPA) et les groupes d’entraide associatifs (Vie Libre, Narcotiques et Alcooliques Anonymes). À partir d’une posture ethnographique, à la fois compréhensive et critique, nous explorons la construction de la « sortie…

Redonner l’envie de manger aux personnes âgées en institution : impact de quatre facteurs environnementaux sur la prise alimentaire et le plaisir lié…

2012

Comme l’ont montré plusieurs travaux, l’entrée en Etablissement d’Hébergement pour Personnes Agées Dépendantes (EHPAD) s’accompagne d’une augmentation du risque de dénutrition (HAS, 2007 ; Sulmont-Rossé et al., 2012). Parmi les facteurs susceptibles d’affecter la prise alimentaire, il a été montré que l’environnement qui entoure le repas (de l’assiette à l’ambiance générale) contribuait fortement à l’appétit et à la prise alimentaire des résidents d’EHPAD (Nieuwenhuizen et al. 2009 ; Nijs et al. 2009). De fait, quatre études ont montré qu’une amélioration globale de l’environnement (changement de mobilier, décoration de la salle à manger, réorganisation du personnel…) pouvait entrainer une …

Temperamentally inhibited children are at risk for poorer maths performance : self-concept as mediator

2020

AbstractIt has repeatedly been found that temperamental inhibition and low academic achievement are associated with each other: children with cautious and wary or shy behaviour are at risk for low academic achievement. Several suggestions about the mechanism behind this association have been made, these highlighting for example, the fewer learning opportunities of cautious and wary children and more negative interaction between teachers and inhibited children. However, the empirical studies about these mechanisms are rare and, thus, they have remained unclear. This study examined whether children’s maths-related self-concept of ability acts as a mediator between their temperamental inhibiti…

Un groupe statuaire complexe à Autun : essai d’identification

2012

Au cours d’un diagnostic réalisé au nord-ouest de la ville d’Autun, à proximité du rempart d’origine augustéenne, un fragment de groupe statuaire a été trouvé au croisement de deux rues antiques. Reposant sur le sol de circulation, il semble avoir été abandonné au cours de l’Antiquité tardive ou du haut Moyen Age. Il se compose d’un personnage cuirassé (cuirasse musclée) vraisemblablement représenté de dos. Il s’agirait d’une gigantomachie, en ronde-bosse (sculpté sur trois cotés), la face principale a été délitée par la cassure de l’arkose taillée en délit (les bancs géologiques locaux sont impuissants à fournir la hauteur nécessaire à ce groupe). Sur ce drapé, on voit se lover dans une at…

Alpha-lipoic acid: molecular mechanisms and therapeutic potential in diabetes.

2015

International audience; Diabetes is a chronic metabolic disease with a high prevalence worldwide. Diabetes and insulin resistance are associated with the development of cardiovascular and nervous diseases. The development of these disorders reflects complex pathological processes in which the oxidative stress caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS) plays a pivotal role. It is widely accepted that diabetes impairs endothelial nitric oxide synthase (eNOS) activity and increases the production of ROS, thus resulting in diminished NO bioavailability and increased oxidative stress. Alpha-lipoic acid (LA) possesses beneficial effects both in the prevention and …

Le score de propension : un guide méthodologique pour les recherches expérimentales et quasi expérimentales en éducation

2016

La méthode du score de propension devient de plus en plus populaire pour estimer les effets causaux d’un programme d’intervention. Si les applications empiriques de cette méthode sont encore rares dans les recherches en éducation, des exemples de son utilisation se trouvent aisément dans d’autres disciplines. Cependant, sa mise en place soulève plusieurs questions. L’objectif de cet article est de fournir des éléments de réponses guidant le chercheur et l’évaluateur du domaine de l’éducation pour l’estimation et l’utilisation du score de propension. Les différentes étapes de son application sont présentées pas à pas : évaluation du biais de sélection, construction du score de propension et …

Relationships between personality traits and values in middle aged men and women

2018

The present study analyzed the relations between the Big Five personality traits (neuroticism, extraversion, agreeableness, conscientiousness, and openness to experience) and 14 values (societal concern, tolerance, protecting nature, caring, dependability, autonomy of thought, autonomy of action, stimulation, hedonism, achievement, tradition, security, conformity, and power) in middle-aged women and men. The 50-year-old participants (women n = 107 and men n = 105) were drawn from the ongoing Finnish Jyväskylä Longitudinal Study of Personality and Social Development. The personality traits were assessed using the 60-item NEO Five Factor Inventory. Values were measured using the 46-item versi…

La croyance dans le fumoir : “The Portrait of Mr. WH”, l’éthique de la croyance de William Kingdon Clifford et l’assentiment selon John Henry Newman

2023

Wilde’s story “The Portrait of Mr. W.H.” blurs literary genres, asserts the importance of the false and plays with reader expectations. It has generated a substantial exege- sis, perhaps lacking in interest in the multi-faceted debates on belief running through the 1870s-1880s. Wilde takes part in that debate through a text of uncertain status and complex editorial history, contrasting Newmanian assent with W.K. Clifford’s ethics of belief (1877), before asserting the supremacy of desire, thus ruining all assent and epistemically justified belief. To the demanding philosophical-religious theories of Clifford and Newman, Wilde responds with an ambiguous, subversive narrative, intended to com…
