This contribution presents an analysis of the novel Lo que está en mi corazón (2001), written by the Chilean author Marcela Serrano. After presenting the story and the feminine themes in it, we analyse the images of the indigenous population in Chiapas. This theme allows us to link the portrayal of the feminine characters to the literary construction of the Zapatista Army of National Liberation [less ▲]

The present work deals with the preparation of stable alumina + silica suspensions with high solid loading for the production of spray-dried composite powders. These composite powders are to be used for reactive plasma spraying whereby the formation of mullite and the coating on a ceramic substrate are achieved in a single step process. Electrostatic stabilisation of alumina and silica suspensions has been studied as a function of pH. Silica suspensions are most stable at basic pH whereas alumina suspensions are stable at acidic pH. The addition of ammonium polymethacrylate (APMA) makes it possible to stabilise alumina and prepare a stable 50 wt% alumina + silica suspension at pH 10. The optimum amounts of dispersant and binder have been determined by zeta potential, viscosity and sedimentation measurements. Spray drying of the suspension yields composite powders whose morphology, size distribution and flowability have been characterized before realizing reactive plasma spraying tests.

We report a laboratory-scale study about the suitability of the plasma spraying process for "in situ" repair of cracks in mullite refractories of industrial furnaces. The "design of experiments" approach is used to investigate how the coating porosity and thickness are influenced by six experimental parameters. Arc current, secondary gas (H 2) flow rate, and stand-off distance are the most significant parameters for both responses. Several interaction terms also affect significantly the thickness response. The validity of the model equations is discussed both from a statistical point of view and regarding the physical credibility of the main model terms. Additional experiments confirm that the measured properties lie into the prediction intervals provided by the model. Using a set of parameters optimized for minimal porosity and high thickness (relevant for the crack repair application), coatings with 6% porosity and 1070 μm thickness can be prepared reproducibly. © 2013 ASM International.

A sample of woodmice caught on the Porquerolles island, 2 km off the French coast (Var), has been studied and compared with other ones collected in Corsica and on the mainland. Some yellow-necked wood mie (A. flavicollis) from Belgium are also included in the comparisons. Sixteen biometrical characters were measured on each wood mouse skull and statistical analyses performed: ANOVA, Student t-test and principal composent analysis. A. sylvaticus are all significantly smaller than the Porquerolles island wood mouse, nearly for all the tested variables. In fact, the size of the Porquerolles island wood mouse is quite comparable to that of the yellow-necked wood mouse. The masticatory system of the Porquerolles island wood mouse is nevertheless more developed than in the yellow-necked, making these forms clearly distinct from each other. Gigantism may be an evolutionary trend developed in response to the depletion of the predator/competitor on the island. [less ▲]

Aims. High angular resolution images of the complex gravitational lens system RXS J1131-1231 (a quadruply imaged AGN with a bright Einstein ring) obtained with the Advanced Camera for Surveys and NICMOS instruments onboard the Hubble Space Telescope are analysed to determine the lens model and to reconstruct the host galaxy. Methods. The lens model is constrained by the relative astrometric positions of the lens and point-like images, and by the extended lensed structures. The non-parametric light distribution is recovered in the source plane by means of back ray-tracing. Results. 1-Precise astrometry and photometry of the four QSO lensed images (A-D) and of the lensing galaxy ( G) are obtained. They are found in agreement with an independent study presented in a companion paper. The position and colours of the X object seen in projection close to the lens are found to be only compatible with a satellite galaxy associated with the lens. 2- The Singular Isothermal Ellipsoid plus external shear provides a good fit of the astrometry of images A-D. The positions of extended substructures are also well reproduced. However an octupole ( m = 4) must be added to the lens potential in order to reproduce the observed lens position, as well as the I-B/I-C point-like image flux ratio. The ellipticity and orientation of the mass quadrupole are found similar to those of the light distribution, fitted by a Sersic profile. The lens (z = 0.295) is found to be a massive elliptical in a rich environment and showing possible evolution with respect to z = 0. 3- The host galaxy ( z = 0.658) is found to be a substantially magnified ( M similar to 9) luminous Seyfert 1 spiral galaxy. The angular resolution is sufficient to see regions where stars are intensively forming. Interaction with a closeby companion is also observed. 4- Finally, in the case of RXS J1131-1231, extended lensed structures do not help much in constraining the lens model. [less ▲]

For foreign currency exchange rates; multi-affine analysis can put quantitatively into evidence the differences between correlated (daily closing market) values and random walks in time dependent data. The H(q) spectrum is presented and discussed here for the USD/DEM and JPY/USD exchange rates. The time-evolution of these ratios is found to be multi-affine. The h(gamma)-curve describing the hierarchy of exponents is numerically obtained. Our findings suggest that the modelling of exchange rate time-evolution from day to day is possible within the framework of modern statistical physics and related to models of turbulence in the physics of fluids. Finally, we argue that there is a multiplicity of information levels in the foreign exchange market such that the "efficient market theory" is a crude oversimplification indeed. [less ▲]

In this paper, we review the various ways in which an infrared stellar interferometer can be used to perform direct detection of extrasolar planetary systems. We first review the techniques based on classical stellar interferometry, where (complex) visibilities are measured, and then describe how higher dynamic ranges can be achieved with nulling interferometry. The application of nulling interferometry to the study of exozodiacal discs and extrasolar planets is then discussed and illustrated with a few examples. [less ▲]

Space‐based nulling interferometry has been identified since 1978 as a promising technique to detect and characterize extrasolar Earth‐like planets. In this talk, I will review the evolution of the multi‐aperture concepts dedicated to Earth‐like planet imaging during the last 30 years, and discuss the future prospects in this field. In particular, I will describe the proposed architecture for the Darwin/TPF‐I mission, which has resulted from a common optimization effort by ESA and NASA and from various industrial studies during the past decade. The main scientific and technical hard points will be critically discussed. This talk will also review the precursor instruments (present and future) that could enable future flagship interferometric missions similar to Darwin/TPF‐I. [less ▲]

Wildlife surveys rely on an accurate taxonomic framework. Identification tools used to reach this goal are not equivalent and may depend on several objectives and constraints, including sampling conservation difficulties, the invasiveness of the sampling techniques, sampling capacity, the relevance of the results, materials needed, the cost and the user time required in the field and laboratory. This article presents and discusses the advantages and limits of each identification tool used in the Ceropath (Community ecology of rodents and their pathogens in South East Asia) program to reach a fast and relevant identification of the rodents sampled. It is concluded that there needs to be a combination of the results from different methods, including the most recent ones, to achieve an improvement in taxonomic identification. [less ▲]

We present our recent results on using previously introduced framework for multi-area security assessment in large interconnections. The basic idea of the framework is exchanging just enough information so that each operator can evaluate the impact in his control area of contingencies both internal and external to his area. We provide illustrations based on a localization concept known as efficient bounding method and recently introduced approximate DC model of the European interconnected system. In this paper we focus on four transmission system operators (within the approximate DC model): Belgium, France, Germany, and Netherlands (for both Summer and Winter-peak load conditions). [less ▲]

The building is not a unique object any more, but results from the assembly of components, among which the envelope is one of the objects assembled. The components are more and more specialised and acquire an actual independence. On the other hand, the components of the building and of the envelope have a large diversity of life cycles; moreover the life duration of the components shortens, because they rapidly become obsolescent from many points of view: technology, technique, performance, functionality, etc., so that their easy transformability, adaptability (and/or removability) becomes an important quality required to them. The conception of new building envelopes must take these aspects into account, in order to obtain a best practice design. [less ▲]
