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 ▲]

The emergence of a territory project built and shared by the actors implies the use of special methods which make it possible to transcend the private interest for the benefit of a territorialized community good. The example of the territorial project for the districts of Huy and Waremme (Belgium, 2007) makes it possible to put forward useful and diversified methods to cause and frame the debates, while taking into account the number, the representativeness and the diversity of the actors in a strongly diversified territory. It deals with the integration of the territorial observation in a territories development process and in the confrontation of the theoretical and pragmatic approaches. [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.

OBJECTIVES: To search for compounds possibly useful for the treatment of Alzheimer's disease. METHODS: Alkaloid fractions from the roots, stems and leaves of Triclisia sacleuxii (Menispermaceae) and pure bisbenzylisoquinoline alkaloids isolated from the roots (phaeanthine, N-methylapateline, 1,2-dehydroapateline and gasabiimine) were assessed for acetylcholinesterase inhibitory activity. KEY FINDINGS: All extracts and compounds tested inhibited acetylcholinesterase to varying degrees; the leaf tertiary alkaloid fractions and the root quaternary alkaloid fractions exhibited the strongest inhibitory potential (90% at 0.1 mg/ml). The leaf tertiary alkaloid fraction was selected for further analysis (the quaternary alkaloids, which are too polar for absorption and brain distribution, were presumed to be clinically uninteresting). TLC bioautography using Ellman's reagent allowed the detection of acetylcholinesterase inhibitors and the isolation of the major active constituent, which was identified as lindoldhamine, a one-bridged bisbenzylisoquinoline alkaloid. Lindoldhamine displayed high acetylcholinesterase inhibitory activity with a 50% inhibition concentration in the micromolar range. CONCLUSIONS: All T. sacleuxii alkaloid fractions tested exhibited anti-acetylcholinesterase activity; isolated bisbenzylisoquinoline alkaloids showed weak-to-high inhibition depending on their structural features. Structure modification could provide interesting derivatives with enhanced anti-acetylcholinesterase activity. [less ▲]

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 ▲]

Stall flutter is a nonlinear aeroelastic phenomenon that can affect several types of aeroelastic systems such as helicopter rotor blades, wind turbine blades, and highly flexible wings. Although the related aerodynamic phenomenon of dynamic stall has been the subject of many experimental studies, stall flutter itself has rarely been investigated. This paper presents a set of experiments conducted on a NACA0012 airfoil undergoing stall flutter oscillations in a low-speed wind tunnel. The aeroelastic responses are analyzed with the objective of characterizing the local bifurcation behavior of the system. It is shown that symmetric stall flutter oscillations are encountered as a result of a subcritical Hopf bifurcation, followed by a fold bifurcation. The cause of these bifurcations is the occurrence of dynamic stall, which allows the transfer of energy from the freestream to the wing. A second bifurcation occurs at the system’s static divergence airspeed. As a consequence, the wing starts to undergo asymmetric stall flutter bifurcations at only positive (or only negative) pitch angles. The dynamic stall mechanism itself does not change but the flow only separates on one side of the wing. [less ▲]

Type VII mucopolysaccharidosis is a very rare recessive lysosomal storage disease. We diagnosed a type VII MPS in a case of severe fetal hydrops after pregnancy termination at 23 weeks of gestation. The diagnosis was suspected on histopathological examination by the presence of foam cells in many viscera and foamy placental Hofbauer cells. Enzyme assay on cultured amniotic cells showed a markedly deficient beta-glucuronidase activity, thus confirming the diagnosis. This report shows the importance of a precise necropsy diagnosis in nonimmune hydrops because of putative implications for genetic counseling and prenatal diagnosis in subsequent pregnancies.

Polymorph minerals are natural materials that share the same composition but have a different structure. Traditionally, the characterization of polymorphs has been done using different techniques of microscopy, X-ray diffraction Raman or IR Spectroscopy for instance. In this work we propose the use of a new technique as an alternative to characterise polymorphs: Ion Beam Induced Luminescence (IBIL). As an advantage to the other techniques, IBIL can be carried out simultaneously with the PIXE technique or other Ion Beam Analysis techniques and the combination will yield results on elemental composition and luminescence properties at the same time. Different minerals have been analysed with IBIL as an example of application to the characterization of polymorphs and its correspondent spectra are explained in this paper. [less ▲]

Aim: This study assesses the impact of serum carboxy-terminal collagen crosslinks (CTX) bone marker feedback (BMF) on adherence to ibandronate treatment in Asian postmenopausal women with osteoporosis. Methods: This was a 12-month (6-monthly phased), randomized, prospective, open-label, multi-center study conducted in 596 (of 628 enrolled) postmenopausal women with osteoporosis (£ 85 years old) who were naı¨ve, lapsed, or current bisphosphonate users. Patients were randomized into two arms: serum CTX BMF at 3 months versus no-BMF. Once-monthly 150 mg ibandronate tablet was administered for 12 months and adherence to therapy was assessed at 6 and 12 months. In addition, patient satisfaction and safety of ibandronate treatment were also assessed. Results: Serum CTX BMF at 3 months showed no impact on adherence. The proportions of adherent patients were comparable in the BMF versus no-BMF arms (92.6% vs. 96.0%, P = 0.16); overall, serum CTX levels were similar for adherent and non-adherent patients. However, BMF patients felt more informed about their osteoporosis (P < 0.001) and more satisfied (P < 0.01) than no-BMF patients. Conclusions: The Asian postmenopausal osteoporosis patients in this study had a high adherence rate to once-monthly ibandronate therapy. Use of serum CTX BMF had no further impact on increasing adherence, but increased treatment satisfaction. [less ▲]

This paper considers the optimal design of mechatronic systems with configuration-dependent dynamics. An optimal mechatronic design requires that, among the structural and control parameters, an optimal choice has to be made with respect to design specifications in the different domains. Two main challenges are treated in this paper: the non-convex nature of the optimization problem and the difficulty in modeling serial machines with flexible components and their embedded controllers. The optimization problem is treated using the direct design strategy which considers simultaneously structural and control parameters as variables and adopts non-convex optimization algorithms. Linear time-invariant and gain-scheduling PID controllers are addressed. This methodology is exploited for the multi-objective optimization of a pick-and-place assembly robot with a gripper carried by a variable-length flexible beam. The resulting design tradeoffs between system accuracy and control efforts demonstrate the advantage of an integrated design approach for mechatronic systems with configuration-dependent dynamics. 2009 Elsevier Ltd.
