Localized modes of failure are classically analyzed by a plastic strain localization criterion given by the vanishing values of the determinant of the acoustic tensor. However, some failure modes do not exhibit any localization pattern and a crucial question appears : what is the proper criterion for diffuse failure ? An answer attempt is proposed in this paper in both frameworks of continuum mechanics and discrete mechanics through the second order work criterion. [less ▲]

The prime objective of GENIE (Ground-based European Nulling Interferometry Experiment) is to obtain experience with the design, construction and operation of an IR nulling interferometer, as a preparation for the DARWIN/TPF mission. In this context, the detection of a planet orbiting another star would provide an excellent demonstration of nulling interferometry. Doing this through the atmosphere, however, is a formidable task. In this paper we assess the prospects of detecting, with nulling interferometry on ESO's VLT, a Hot Jupiter, a giant planet in a close orbit around its parent star. First we discuss the definition of the optimal target. Then we present a simulated observation of the Tau Bootis system, which suggests that GENIE, in a L'-band single Bracewell configuration, could detect the hot Jupiter in a few hours time with a signal-to-noise ratio of up to ~80. Although there are strong requirements on the control-loop performance, background subtraction and accuracy of the photometry calibration, we conclude that at present there do not seem to be fundamental problems that would prevent GENIE from detecting hot Jupiters. Hence the answer to the question in the title is yes. [less ▲]

This study prospected whether Western blot analysis could be an alternative to radio-immunoassay (RIA) for sheep pregnancy diagnosis. Blood samples were taken from Boujaâd ewes (n= 9) and Boujaâd x D’man (BD) cross breed (n= 12). The pregnancy associated glycoproeins (PAGs) were weekly monitored in plasma during the whole gestation and the first month postpartum by two RIA systems (El Amiri et al., 2007, Reprod Domest Anim 42:257-62). The highly immunoreactive samples derived from PAG profiles were tested using Western blot based on the same antiserum used in RIA. Each week (from the 13th to the 19th week), two pools of plasma samples (4 ml each) were taken from single and multiple lambing ewes respectively. Samples were submitted to a protein extraction at neutral pH, followed by ammonium sulfate (A.S.) precipitation, dialysis, and lyophilization. The placental extract was used as a check. Results revealed that ewes with multiple lambs presented numerically higher PAG concentrations. In both RIA systems, the high concentrations were recoded around the 19th week of gestation and the maximal concentrations varied from 120 to 700 ng/ml. In Western blot, the placental extracts reacted positively while the plasma samples did not give any positive reaction. In conclusion, the RIA remains the only sensitive method to measure PAGs in plasma. The present study strengthens the need to develop an ELISA kit as an alternative to RIA systems. [less ▲]

The aim of this paper is to present a user-oriented protocol for the characterization of colour attributes in an urban fragment. The challenge is to provide quantitative answers to these questions: how is colour organized? How does it develop a structure in the city? Our research investigates stable colour typologies. The obvious lack of effective tools for the chromatic assessment in the field of urban design was the main motivation of this research. The protocol is illustrated within the study of the “rue des Anglais” in Liège (Belgium) and the stability of the method is conducted through a series of validations. [less ▲]

L'article critique la revendication "d'universalisme" qui accompagne si souvent la radicalité laïque. Pour ce faire, il s'appuie sur la distinction de Michael Walzer entre "universalisme surplombant", c'est-à-dire dogmatique et "universalisme réitératif", c'est-à-dire issu d'une redécouverte à travers chaque culture. Il montre que le féminisme particulier de Carol Gilligan peut être interprété comme une illustration avant la letttre de l'universalisme réitératif. [less ▲]

Témoin fondamental pour l’étude du bâti, le traité d’architecture constitue une source textuelle et iconographique, et plus généralement un document contextuel, qui détermine les règles de l’architecture dans ses dimensions les plus vastes : culturelles, sociales, économiques, techniques… Ainsi, dans le domaine de la « peinture d’impression », les auteurs nous livrent aussi bien des informations d’ordre technique (matières et mises en œuvre) que les usages d’une architecture pensée et écrite avec soin, dans laquelle chaque élément – et chaque couleur – occupe une place bien déterminée. Si la couleur des « dedans » prend naturellement le dessus dans une conception française de l’architecture qui a poussé au plus haut point l’art de la distribution, la couleur des « dehors » n’est néanmoins pas négligée. Aussi trouverons-nous dans les traités d’architecture les techniques et les usages qui conviennent aux « dehors » ; informations qui sont susceptibles de guider le restaurateur dans les choix d’intervention qu’il projette sur le bâti ancien.

At the diagnosis disclosure, the patient recognized having concealed for 7 years a neoplastic wound replacing one of her breasts.

Using first-principles calculations, the phonon frequencies at the Gamma-point and the dielectric tensor are determined and analysed for the cubic and rhombohedral phases of BaTiO3. The dipole-dipole interaction is then separated a la Cochran from the remaining short-range forces, in order to investigate their respective influence on lattice dynamics. This analysis highlights the delicate balance of forces leading to an unstable phonon in the cubic phase and demonstrates its extreme sensitivity to effective charge changes. Within our decomposition, the stabilization of the unstable mode in the rhombohedral phase or under isotropic pressure has a different origin. [less ▲]
