Through a cross-disciplinary approach the authors provide an analysis of the large impact of the Early Warning Mechanism introduced in the Treaty of Lisbon with the goal of involving National Parliaments (NPs) in the European normative production and, consequently, contributing to a higher “democraticity” of EU decision-making process. The involvement of NPs should increase compliance with the principle of subsidiarity and overcome the traditional democratic deficit. The paper – through a critical perspective- concludes connecting the weakness of more democratising procedures with some crucial peculiarities of the prevailing EU integration paradigm. [less ▲]

Anne de Bretagne est la dernière duchesse de Bretagne et la seule femme à être couronnée reine de France deux fois, comme épouse de Charles VIII puis de Louis XII. Bien que sa position comme duchesse de Bretagne lui donne une place de pion sur l’échiquier politique, elle utilise son mécénat artistique afin de faire valoir ses intérêts personnels et territoriaux. Dans ses manuscrits enluminés, exécutés par des principaux artistes français, elle accorde une place importante à Sainte Anne, sa sainte patronne, et à la Vierge, saintes avec qui elle s’identifie, en attendant son propre héritier, comme mères bénies par dieu. Malgré ses alliances avec la France, elle n’oublie jamais sa chère Bretagne désormais incorporé dans le royaume de France : à Nantes par exemple elle honore ses parents avec un tombeau magnifique, qui renforce un sens de nationalité bretonne.

Le rôle joué par les femmes de pouvoir au Moyen Âge et au tout début de la Renaissance dans la commande d’œuvres artistiques et culturelles constitue un champ de recherche de plus en plus prolifique. La présente collection d’articles, suscitée par une journée d’études intitulée "Le mécénat féminin en France et en Bourgogne (XVe-XVIe siècles). Nouvelles perspectives", qui a eu lieu à l’Université de Liège en 2010, illustre l’importance des femmes mécènes, en France et en Bourgogne, dans les domaines de l’architecture, de l’orfèvrerie, des manuscrits enluminés, de la peinture et de la sculpture, ainsi que dans la traduction et dans l’organisation des cérémonials. Dans leurs fonctions respectives, celles de reine, reine mère, duchesse, régente, dame d’honneur, les femmes font usage des œuvres d’art et des rites pour promouvoir leurs intérêts personnels et dynastiques, confrontées qu’elles sont aux difficultés liées à leur sexe et à leur statut de femme de pouvoir, ou à des difficultés telles que les rivalités, la guerre, ou la folie. Même s’il est clair que les cours française et bourguignonne constituent l’espace le plus favorable à l’efflorescence du mécénat féminin, cette collection démontre toutefois l’existence d’un même phénomène, important, en dehors des sphères royales.

The degradation of concrete structures due to chlorides and sulphates penetration is of obvious importance in civil engineering as having major impact on structural durability. In this paper, the results of an investigation on the effect of contaminated crushed concrete aggregates on mechanical properties and durability of recycled concrete are presented. Natural aggregates concrete (NC) slabs were cured in water, sea water, chloride solutions or sulphate solutions and then crushed to obtain virgin and contaminated (polluted) recycled aggregates. The properties of natural (NA) and recycled aggregates (RA) and the mechanical properties and durability performances of a new concrete made from 100% of RA are analysed. The results show that contaminated RA are much sensitive to chlorides than sulphates and are rapidly leached when soaked into water. Significant differences were observed between the properties of original and new concrete and the results clearly show the necessity of taking these contaminations into account. [less ▲]

The temperature effect on the mechanical and tribological behaviors of a microelectromechanical systems cantilever is experimentally investigated using an atomic force microscope. A nonlinear variation of the bending stiffness of microcantilevers as a function of temperature is determined. The variation of the adhesion force between the tip of atomic force microscope (AFM) probe (Si3N4) and the microcantilever fabricated in gold is monitored at different temperatures. Using the lateral mode operation of atomic force microscope, the influence of temperature on friction coefficient between the tip of AFM probe and microcantilever is presented. Finite element analysis is used to estimate the thermal field distribution in microcantilever and the axial expansion. [less ▲]

Aeolian silts (loess) are near surface deposits covering about 10% of the continent surfaces . Therefore a good knowledge of their mechanical behavior is an issue for designing subsurface engineering structures. Usually this material is considered as homogeneous for an engineering point of view. Aeolian silt deposits are continuously well developed in Hesbaye Region (Belgium) reaching locally 20m thick (see document in attachment). They are mainly related to the last interglacial (Eemian) and glacial (Weichselian) periods . Nevertheless the pedostratigraphical, chronostratigraphical and paleoclimatic approaches have shown these silt deposits are usually composed of a series of paleosoils (i.e. Rocourt soil, Humiferous Complex of Remicourt, Harmignies Soil, Nagelbeek Tongued Horizon) interbedded with stratified or homogeneous aeolian silt layers. This study aims to characterize the variability of the in situ mechanical characteristics of the loess deposits from Hesbaye Region at the site scale and at the laboratory scale. Cone penetration tests (CPT), electrical resistivity tomographies (ERT) and drillings have been performed through a 10m thick loess layer in an investigation site located close to the CBR’s Romont quarry (Eben-Emael, Belgium) . Continuous undisturbed silt samples from drillings have been physically (granulometry, Atterberg limits, water content, organic matter content, carbonate content) and mechanically (oedometer test, triaxial test) characterized at the laboratory. Mechanical behavior and physical characteristics have underlined a series of layers with variable mechanical properties through depth. Some of these layers correlated with a detailed stratigraphy cross-section close to the investigation site could correspond to well-known paleosoils. [less ▲]

At the microscale, classical bearings such as ball bearings, sliding bearings and other pivots may be difficult to manufacture. Among all possible solutions to replace them, the notch hinge seems to be very attractive through its many advantages. The major limitation is on the rotation angle. This paper presents a new simplified analytical model for the prediction of the maximum angular displacement and the angular stiffness of a notch hinge. To validate our model, an experimental set-up has been developed. Finally, the results are compared to other theories. [less ▲]

Ferritic stainless steels are corrosion resistant steels with a low and stable cost. Widely used in automotive applications, structural applications using ferritic stainless steels are only emerging mainly because ferritics are partially covered by structural standards due to a shortage of design data. Computer models are more and more used to support the developments of conventional design methods based on expensive full-scale tests or trial and errors methods. And for the modeling of metal forming processes as well as structural behavior of members, it is necessary to afford an accurate knowledge of the mechanical properties. In this paper, the experimental investigations made on the chromium based alloy 3Cr12 (1.4003) in order to characterize its mechanical behavior are presented. During the research, a classical uniaxial experimental equipment and a bi-axial experimental equipment designed by Flores (2005) in the Structures Laboratory of the University of Lige have been used. The collection of tests performed included tensile tests, cyclic shear tests, simple shear tests and successive simple shear and plane-strain tests. The yield locus and the hardening models are presented and identified in a companion paper by the same author. [less ▲]

In practice, the finite element method is quite successful in simulating the metal forming processes or the structural behavior of members carrying loads. The accuracy of such models largely depends on the mechanical laws used to describe the material behavior. Numerous authors have shown the effect of material anisotropy on deep drawing or the influence of non-linear hardening behavior on the resistance of structural members. Studies have also demonstrated how important the evaluation of the material parameters is during the theoretical calculation of the strength of stainless steel members for instance. Non-linear metallic materials emerge as an alternative to elastic perfectly plastic materials, be it for their stainless, ductility or strength properties. It is thus necessary to be able to accurately model their material behavior. In the present paper, prior to any computations, different laws are described: simple phenomenological law and micro–macro constitutive models based on crystal plasticity. Classical yield surface such as Hill one are combined with isotropic (Swift or Ramberg– Osgood) and kinematic (Armstrong–Frederick or Teodosiu–Hu) hardening models to define the material behavior. The material parameters included in each law are then carefully identified. For that purpose, the experimental equipment developed by Flores (2005) in the Structures Laboratory of the University of Liege was used to perform biaxial tests. Coupled with classical uniaxial tests, they provide the necessary data for the identification of the yield locus and the hardening models. [less ▲]

The paper proposes two numerical models ot the mechanical behaviour of chalk. First, an elasto-plastic constitutive law reproduces the different plastic mechanisms of the chalk and the influence of pore fluids by introducing the concept of suction. Secondly, a model able to reproduce time dependence behaviour. Eventually, the paper gives a simulation of an academic reservoir during depletion and waterflooding phase. [less ▲]
