This article gives a report on the territorial collection of information for the local actors in the whole of Europe (EU 27). It deals with various sources available in Europe in a centralized and decentralized way. An inventory was carried out for indicators selected within the framework of the method CATALYSE of confrontation of the populations needs with the services available to answer it. Various examples of information sources for the territories (“observatories”) are also putted forward. The reasoned catalog treats methods of cartographic representation for the various indicators. It also highlights the variability of the indicators definitions according to the European suppliers, and the difficulties of harmonization and use. [less ▲]

Research in songbirds shows that singing behavior is regulated by both brain areas involved in vocal behavior as well as those involved in social behavior. Interestingly, the precise role of these regions in song can vary as a function of the social, environmental and breeding context. To date, little is known about the neurotransmitters underlying such context-dependent regulation of song. Dopamine (DA) modulates highly motivated, goal-directed behaviors (including sexually motivated song) and emerging data implicate DA in the context-dependent regulation of singing behavior. This study was performed to begin to examine whether differences in DA receptors may underlie, in part, context-dependent differences in song production. We used autoradiographic procedures to label D1-like and D2-like DA receptors to examine the relationship between DA receptor density and singing behavior in multiple contexts in male European starlings (Sturnus vulgaris). Within a breeding context (when testosterone (T) was high), D1-like receptor density in the medial preoptic nucleus (POM) and midbrain central gray (GCt) negatively correlated with song used to attract a female. Additionally in this context, D1-like receptor density in POM, GCt, medial bed nucleus of the stria terminalis (BSTm), and lateral septum (LS) negatively correlated with song likely used to defend a nest box. In contrast, in a non-breeding context (when T was low), D1-like receptor density in POM and LS positively correlated with song used to maintain social flocks. No relationships were identified between song in any context and D2-like receptor densities. Differences in the brain regions and directional relationships between D1-like receptor binding and song suggest that dopaminergic systems play a region and context-specific role in song. These data also suggest that individual variation in singing behavior may, in part, be explained by individual differences in D1-like receptor density in brain regions implicated in social behavior.

This article presents the carried out researches within the framework of the creation of an indicators gate for the local actors. We evaluate in this one the accessible territorial data for the actors, and the cartographic files of the administrative or statistical entities to represent them. We analyze the sources of information, and determine its accessibility in the various countries of the European Union. We moreover deal with problems of the relevant territorial scales and cartographic representation of the data. [less ▲]

Electron tomography and image analysis are combined to characterize ordered mesoporous silica SBA-15. The morphology of the mesopores with average diameter 6 nm is analyzed in terms of cylinders having variable radii and centers that are statistically centered on the points of a distorted hexagonal lattice. The variations in the mesopore centers and radii add up and result in pore wall corrugation with amplitude of 1.6 nm. The correlation length of the corrugation along the pore axis was found to be 4-5 nm. The amplitude of the corrugation compared well with the 1.9 nm thick microporous corona obtained from X-ray diffraction (XRD). In general, the present approach provides a detailed microscopic 3D model of nanostructured materials that complements macroscopic measurements such as physisorption and XRD. [less ▲]

This paper discusses the integrated design of mechatronic systems with varying dynamics, such as serial and parallel machine tools. This characteristic affects the machine stability and performance. A computer-aided integrated design methodology is proposed and validated on a pick-and-place robot. It consists of two main steps: (i) the derivation of reduced models from a flexible multibody model and (ii) the systematic robust control design. Eventually, the integrated design of the system, considering both structural and control parameters, can be performed. [less ▲]

The landscape of a nature park is not a relic landscape but a living cultural landscape. The paper questions the conformity of the landscape in the regional nature park of the Attert valley. It analyses more specifically (1) the conformity to the natural environment and the economic context, (2) the conformity from a semiotic or cultural point of view, and (3) the recognition and the management of the landscape as heritage. It states that few landscape features are preserved from the past. Nevertheless the landscape of the Attert valley maintains an identity due to old settlements, and the influence of the natural environment. The rural policy of renovation since 1970, together with the regional nature park activities, and the coming landscape Charter are useful tools to manage the landscape. However, these tools experience trouble with restraining the increase of real-estate due to the proximity of the Great Duchy of Luxembourg. [less ▲]

A methodology for the numerical simulation of bird strike on a nose radome structure of an aircraft is presented. The simulation technique is based on a non-linear dynamic finite element analysis and is performed in two steps. The first step deals with the choice of suitable material models capable of repre-senting the behaviors of the material systems used in the impact process. The second step deals with the nu-merical simulation of bird strike on aircraft radome structure. The influence on the numerical results of the critical modeling issues such as the mesh density, the substitute bird flexibility and contact interfaces param-eters are discussed briefly, and the of strain rate effect of material is presented by comparison calculations. Then, the analytical method is employed to predict the amount of energy absorbed by the radome structure. As the impact location varied, the tendency of the energy absorbed by the structure is given.

We present the rationale, the background and the structure for version 2.0 of the GENESTAT information portal (www.genestat.org) for statistical genetics. The fast methodological advances, coupled with a range of standalone software, makes it difficult for expert as well as non-expert users to orientate when designing and analysing their genetic studies. The ultimate ambition of GENESTAT is to guide on statistical methodology related to the broad spectrum of research in genetic epidemiology. GENESTAT 2.0 focuses on genetic association studies. Each entry provides a summary of a topic and gives links to key papers, websites and software. The flexibility of the internet is utilised for cross-referencing and for open editing. This paper gives an overview of GENESTAT and gives short introductions to the current main topics in GENESTAT, with additional entries on the website. Methods and software developers are invited to contribute to the portal, which is powered by a Wikipedia-type engine and allows easy additions and editing. [less ▲]

Discontinuous Galerkin (DG) methods provide a means of weakly enforcing the continuity of the unknown-field derivatives and have particular appeal in problems involving high-order derivatives. This feature has previously been successfully exploited (Comput. Methods Appl. Mech. Eng. 2008; 197:2901-2929) to develop a formulation of linear Kirchhoff-Love shells considering only the membrane and bending responses. In this proposed one-field method - the displacements are the only unknowns, while the displacement field is continuous, the continuity in the displacement derivative between two elements is weakly enforced by recourse to a DG formulation. It is the purpose of the present paper to extend this formulation to finite deformations and non-linear elastic behaviors. While the initial linear formulation was relying on the direct linear computation of the effective membrane stress and effective bending couple-stress from the displacement field at the mid-surface of the shell, the non-linear formulation considered implies the evaluation of the general stress tensor across the shell thickness, leading to a reformulation of the internal forces of the shell. Nevertheless, since the interface terms resulting from the discontinuous Galerkin method involve only the resultant couple-stress at the edges of the shells, the extension to non-linear deformations is straightforward.
