The issue of jurisdiction certainly constitutes one of the main challenges of what is commonly called globalisation, i.e. the rapid internationalisation of economic (and, to a somewhat lesser extent, of other) activities. Since legal regulation of these human activities is still largely state-based with the notable exception of the European Union, whose existence and the large body of rules it produces, also raises questions of jurisdiction rules on jurisdiction are necessary to define which part of these activities can be subject to regulation by a given State. This paper aims to examine what private international law has achieved to answer the question of jurisdiction. [less ▲]

The structural, textural and morphological evolution of calcined surfactant-free mesoporous molecular sieves treated in boiling water was investigated and explained by a three-step mechanism. The materials, prepared by a non-ionic surfactant [C16(EO)10] templating pathway, undergo a sharp decrease in surface area and pore size at the initial stage due to the partial hydrolysis of the silica walls. Then, the dissolution of the resulting branched (Si-O-)n chains attached to the internal surface of the pores results in a gain of surface area and pore size. Finally, the loss in surface area and the sharp increase in pore sizes is due to the destruction of the pore walls and thus of the materials. © 2004 Elsevier B.V. All rights reserved. [less ▲]

We discuss passive nonlinear energy pumping from a linear (main) mechanical structure to a weakly coupled, local, passive nonlinear energy sink (NES). We show that the NES can be designed to effectively absorb vibrational energy from the main structure in a one-way, irreversible fashion. We demonstrate the occurrence of pumping cascades, where an appropriately designed NES passively extracts energy sequentially from a number of modes of the main (linear) structure, interacting individually with each mode before moving to the next. Experimental results confirm our theoretical findings. The applications of the nonlinear energy pumping phenomenon to the problem of vibration and shock isolation will be discussed [less ▲]

Proposal of a method of hydro-geomorphological typology of rivers and test of a sub-basin of the Rhône River (Yzeron basin). The paper proposes a hydro-geomorphological typology method of watercourses that might potentially be used in western Europe. The method was tested in the Yzeron basin (France). Field data were collected and analysed by multivariate statistics. Statistical results were consistent with the results of the typology model. Some recommendations are also made for the future development of automatic methods of characterization-sectorization of rivers. [less ▲]

The goal of this research is to study the anisotropic material behavior during forming processes, represented by both complex yield loci and kinematic-isotropic hardening models. A first part of this paper describes the main concepts of the ‘Stress-strain interpolation’ model that has been implemented in the non-linear finite element code Lagamine. This model consists of a local description of the yield locus based on the texture of the material through the full constraints Taylor’s model. The texture evolution due to plastic deformations is computed throughout the FEM simulations. This ‘local yield locus’ approach was initially linked to the classical isotropic Swift hardening law. Recently, a more complex hardening model was implemented: the physically-based microstructural model of Teodosiu. It takes into account intergranular heterogeneity due to the evolution of dislocation structures, that affects isotropic and kinematic hardening. The influence of the hardening model is compared to the influence of the texture evolution thanks to deep drawing simulations. [less ▲]

The momentum transfer dependence of the slopes of the spin-non-flip and spin-flip amplitudes is analyzed. It is shown that the long tail of the hadronic potential in impact parameter space leads, for hadron-hadron interactions, to a larger value of the slope for the reduced spin-flip amplitude than for the spin-non-flip amplitude. It is also shown that the preliminary measurement of A(N) obtained by the E950 Collaboration confirms such behavior of the hadron spin-flip amplitude. [less ▲]

Studies of eukaryotic genome expression demonstrate the importance of steroid receptor coactivators in mediating efficient gene transcription. Little is know about the physiological role of these coactivators in vivo. We recently showed that the Steroid Receptor Coactivator SRC-1 is densely expressed in steroid-sensitive brain areas in birds and its expression is steroid-dependent and sexually differentiated. We tested the role of SRC-1 in the activation by testosterone of male sexual behavior in quail. Daily injections of LNA antisense oligonucleotides in the third ventricle (AS group) significantly reduced the expression of male copulatory behavior in response to exogenous testosterone compared to control animals (Ctrl group) receiving the vehicle alone or scrambled LNA. Sexual behavior was restored and even enhanced within 48 hours after interruption of LNA injection (ASSC group). Western blot analysis confirmed the decrease of SRC-1 expression in AS animals and suggested an over-expression of the coactivator in ASSC animals. The effect of SRC-1 knock down on behavior was correlated with a reduced volume of the medial preoptic nucleus (POM) defined by Nissl-staining and aromatase immunohistochemistry. In addition, the amount of aromatase-immunoreactive material in POM, defined as the relative optical density of the aromatase immunoreactivity multiplied by the percentage of surface covered within the nucleus and by the total POM volume of the POM, was decreased in the AS compared to the Ctrl group, suggesting a blockade of aromatase transcription. Together, these data indicate that SRC-1 functions as a critical regulatory molecule in the brain that modulates steroid-dependent gene transcription and behavior. [less ▲]

Small-angle neutron scattering is used to investigate the self-assembling behaviour of poly( ε-caprolactone)-b-poly(ethylene oxide) diblock copolymers with various block lengths (i) in aqueous solution, (ii) in aqueous solution with the addition of sodium dodecyl sulphate (SDS) and (iii) at the silica-water interface. Micelles are observed under our experimental conditions due to the very small critical micellar concentration of these copolymers (0.01 g/l). The poly( ε-caprolactone) core is surrounded by a poly(ethylene oxide) corona. The micellar form factors have been measured at low copolymer concentrations (0.2 wt%) under selected contrast matching conditions. The data have been fitted to various analytical models to extract the micellar core and corona sizes. SDS is shown to induce partial micelle disruption together with an increase of the poly(ethylene oxide) corona extension from 25% (without SDS) to 70% (with SDS) of a completely extended PEOi u chain. Our data at the silica-water interface are compatible with the adsorption of micelles. [less ▲]

Radiometric dates, typology and sedimentology suggest an autochthonous origin for the Gravettian culture in the Middle Danube. Its complex development is marked by tool specialisation, a demographic increase and an apparent sedentism. Subsequently, this key region spread to the east or the west by autonomous migratory movements during each phase (Bayacian, Kostenkian). The form of religiosity that is finally associated with this culture constitutes the first artistic creation evidencing a matriarchal system. Through the artistic forms, this belief system is also modified through time and across space: it is characterised as well by recognisable artistic “styles”. The broad Gravettian entity, in its distribution and the finesse of its adaptation, was a product of continental Europe, for which it constitutes the origin of later cultures and populations. At the same time, its plastic expressions seem to result in an Aurignacian acculturation, and its anatomy a blend of Neandertals with incoming modern humans. Curiously, recent phases are limited to the eastern Danube Basin. The Pleniglacial B seems to have interrupted western contacts, where the Magdalenians would soon appear, until Moravia. From then on, Europe as a whole would no longer be unified. In consequence, new approaches to the study of the Danubian Gravettian should be oriented towards the eastern plains, Moldavia and The Crimea. [less ▲]

Observations of Jupiter carried out by the Chandra ACIS-S instrument over 24-26 February, 2003, show that the auroral X-ray spectrum consists of line emission consistent with high-charge states of precipitating ions, and not a continuum as might be expected from bremsstrahlung. The part of the spectrum due to oxygen peaks around 650 eV, which indicates a high fraction of fully-stripped oxygen in the precipitating ion flux. The OVIII emission lines at 653 eV and 774 eV, as well as the OVII emission lines at 561 eV and 666 eV, are clearly identified. There is also line emission at lower energies in the spectral region extending from 250 to 350 eV for which sulfur and carbon lines are possible candidates. The Jovian auroral spectra differ significantly from measured cometary X-ray spectra. The charge state distribution of the oxygen ion emission evident in the measured auroral spectra strongly suggests that, independent of the source of the energetic ions (magnetospheric or solar wind) the ions have undergone additional acceleration. For the magnetospheric case, acceleration to energies exceeding 10 MeV is apparently required. The ion acceleration also helps to explain the high intensities of the X-rays observed. The phase space densities of unaccelerated source populations of either solar wind or magnetospheric ions are orders of magnitude too small to explain the observed emissions. The Chandra X-ray observations were executed simultaneously with observations at ultraviolet wavelengths by the Hubble Space Telescope and at radio wavelengths by the Ulysses spacecraft. These additional data sets provide interesting hints as to the location of the source region and the acceleration characteristics of the generation mechanism. The combined observations suggest that the source of the X rays is magnetospheric in origin, and that strong field-aligned electric fields are present which simultaneously create both the several-MeV energetic ion population and the relativistic electrons believed to be responsible for the generation of 40 minute quasi-periodic radio outbursts.

Numerical crack propagation schemes were augmented in an elegant manner by the X-FEM method applied to fracture mechanics. The use of special tip enrichment functions, as well as a discontinuous function along the sides of the crack allows one to do a complete crack analysis virtually without modifying the underlying mesh, which is of an evident industrial interest. The conventional approach for crack tip enrichment (described in [2,3]) is that only a specific layer of elements are enriched around the crack tip. We show that this “topological” approach does not yield an increase of the order of the asymptotic convergence rate when compared to unenriched finite elements, as when the crack is part of the mesh. It rather modifies the proportionality factor of the asymptotic convergence rate. In this study, we propose another enrichment scheme which yields a convergence rate that appears to be close to that of regular finite elements used when the solution field does not show singularities. The enriched basis in X-FEM degrades the rigidity and mass matrices condition numbers (the mass matrix typically appears in case of time dependent problems such as wave propagation in cracked bodies). To recover the condition number of non enriched matrices, we introduce a preconditioning strategy which acts block-wise on the set of enriched degrees of freedom associated to each node. This strategy uses a local (nodal) Cholesky based decomposition. Another issue is brought by the integration scheme used to build the matrices. The nature of the asymptotic functions are such that any Gauss-Legendre based integration scheme will only poorly converge with respect of the order of the quadrature. We propose a modified integration scheme to handle that issue. We apply the new technique developed to the estimation of stress intensity factors along the crack front of 3D cracks and use these SIFs for crack propagation using a Paris type fatigue law.
