Purpose: To assess the feasibility of a method based on microwave spectrometry to detect structural distortions of metallic stents in open air conditions and envisage the prospects of this approach toward possible medical applicability for the evaluation of implanted stents. Methods: Microwave absorbance spectra between 2.0 and 18.0 GHz were acquired in open air for the characterization of a set of commercial stents using a specifically design setup. Rotating each sample over 360º, 2D absorbance diagrams were generated as a function of frequency and rotation angle. To check our approach for detecting changes in stent length (fracture) and diameter (recoil), two specific tests were performed in open air. Finally, with a few adjustments, this same system provides 2D absorbance diagrams of stents immersed in a water-based phantom, this time over a bandwidth ranging from 0.2 to 1.8 GHz. Results: The authors show that metallic stents exhibit characteristic resonant frequencies in their microwave absorbance spectra in open air which depend on their length and, as a result, may reflect the occurrence of structural distortions. These resonances can be understood considering that such devices behave like dipole antennas in terms of microwave scattering. From fracture tests, the authors infer that microwave spectrometry provides signs of presence of Type I to Type IV stent fractures and allows in particular a quantitative evaluation of Type III and Type IV fractures. Recoil tests show that microwave spectrometry seems able to provide some quantitative assessment of diametrical shrinkage, but only if it involves longitudinal shortening. Finally, the authors observe that the resonant frequencies of stents placed inside the phantom shift down with respect to the corresponding open air frequencies, as it should be expected considering the increase of dielectric permittivity from air to water. Conclusions: The evaluation of stent resonant frequencies provided by microwave spectrometry allows detection and some quantitative assessment of stent fracture and recoil in open air conditions. Resonances of stents immersed in water can be also detected and their characteristic frequencies are in good agreement with theoretical estimates. Although these are promising results, further verifica tion in a more relevant phantom is required in order to foresee the real potential of this approach.

Extensible Dependency Grammar (XDG; Debusmann, 2007) is a flexible, modular dependency grammarframework in which sentence analyses consist of multigraphs and processing takes the form of constraint satisfaction. This paper shows how XDGlends itself to grammar-driven machine translation and introduces the machinery necessary for synchronous XDG. Since the approach relies on a shared semantics, it resembles interlingua MT.It differs in that there are no separateanalysis and generation phases. Rather, translation consists of the simultaneousanalysis and generation of a single source-target sentence.

A Catalunya, en els darrers anys, han anat proliferant una sèrie de «professionals» que realitzen, amb més o menys adequació a la definició teòrica, la funció de mediadors inter-culturals. Primerament, es tractava de gitanos, però darrerament, fruit de l’increment de la presència d’infants d’origen immigrant a les escoles catalanes, s’ha vist créixer el nombre i el protagonisme dels estrangers pel reconeixement que se’ls ha donat des de l’Administració i des de les institucions. Els mediadors han intentat intervenir en qüestions com ara la participació dels pares d’origen minoritari, l’adaptació del currículum a la diversitat cultural, la negociació de conflictes culturals, la desescolarització, l’absentisme i l’abandonament escolar dels alumnes durant el període d’escolarització obligatòria, la traducció lingüística i la interpretació sociocultural, etc. Concretament, la nostra recerca ha consistit en vint-i-set entrevistes en profunditat a mediadors interculturals de tot Catalunya.

En Cataluña en los últimos años, han ido proliferando una serie de "profesionales" que realizan, con más o menos adecuación a la definición teórica de mediador intercultural, dicha función. Primeramente se trataba de gitanos, pero recientemente, fruto del incremento de la presencia del alumndado de origen inmigrante en las escuelas, se ha visto crecer el número y el protagonismo de los mediadores de extranjero, sobre todo por el reconocimiento que se les ha otorgado desde la administración y las instituciones. Concretamente, los mediadores interculturales han intentado intervenir en cuestiones como la participación de los padres de origen inmigrante en los centros escolares, la adaptación del currículum a la diversidad cultural, la negociación de conflictos "culturales" (el uso del pañuelo en las clases, los menús del comedor...), la desescolarización, absentismlo y abandono escolar de los alumnos durante el período de la escoalrización obligatoria, la traducción lingüística y la interpretación sociocultural., etc. Al ser una práctica nueva, está aún llena de interrogantes, pero, como no se estaba produciendo paralelamente una reflexión y clarificación de sus fundamentos, nos parecía un momento pertinente para examinarla. Así pues, pretendemos profundizar en esta figura a partir de un trabajo empírico que ha consistido en 22 entrevistas en profundidad a mediadores de origen inmigrante que trabajan en las instituciones escolares de Cataluña.

En los últimos años la traducción lingüística y la mediación intercultural se han convertido en un ejercicio cada vez más presente y utilizado en servicios e instituciones educativas de Cataluña; tal como se acostumbra a decir popularmente, la práctica va por delante de la teoría y en este caso es muy cierto. A pesar de este bagaje, dicha práctica se manifiesta llena de interrogantes y, sin embargo, no se está produciendo paralelamente una reflexión y clarificación de su funcionamiento. Por ello, nos pareció que nos hallábamos en un momento adecuado para examinarla, ya que se están tomando diversas iniciativas de formación y actuación de mediadores, en este último caso casi siempre en relación con situaciones o marginación de determinados grupos etnoculturales.

En Cataluña, en los últimos años, ha ido proliferando una serie de «profesionales » que realizan, con más o menos adecuación a la definición teórica de mediador intercultural, dicha función. Concretamente, los mediadores interculturales intervienen en cuestiones como la participación de los padres de origen minoritario en los centros escolares; la adaptación del currículum a la diversidad cultural; la negociación de conflictos «culturales» (la carne de cerdo en el comedor escolar, el uso del pañuelo...); la desescolarización; absentismo y abandono escolar de los alumnos durante el período de la escolarización obligatoria; la traducción lingüística y la interpretación sociocultural, etc. La experiencia adquirida1 nos indica de forma clara cuáles son los problemas que se producen con más frecuencia y las vías de solución que han resultado más eficaces.

En els anys vuitanta i noranta, Maria Àngels Anglada s’endinsà en l’art de la traducció i traslladà alguns títols, majoritàriament clàssics, amb l’objectiu de recuperar noms poc atesos pels discursos literaris del nostre país. Se centrà en quatre textos: Les germanes de Safo (1983), Epigrames (1993), L’esplanada (1987), i, amb Maria Ohannesian, Terra porpra i altres poemes. Anglada també va fer feina de torsimany en els seus tres llibres de viatges Paisatge amb poetes (1988), Paradís amb poetes (1993) i Retalls de la vida a Grècia i Roma (1997).

In this paper the authors propose a new closed contour descriptor that could be seen as a Feature Extractor of closed contours based on the Discrete Hartley Transform (DHT), its main characteristic is that uses only half of the coefficients required by Elliptical Fourier Descriptors (EFD) to obtain a contour approximation with similar error measure. The proposed closed contour descriptor provides an excellent capability of information compression useful for a great number of AI applications. Moreover it can provide scale, position and rotation invariance, and last but not least it has the advantage that both the parameterization and the reconstructed shape from the compressed set can be computed very efficiently by the fast Discrete Hartley Transform (DHT) algorithm. This Feature Extractor could be useful when the application claims for reversible features and when the user needs and easy measure of the quality for a given level of compression, scalable from low to very high quality.

This paper reviews some of the most usual definitions of stress and trauma including the notion of accumulative trauma. Then, the Spanish version of the Cumulative Trauma Scale by Kira et al (2008) is presented. It has been developed by following a process of translation and by applying it to two small groups of subjects to test it for comprehension (pilot test).

The relevance of the fragment relaxation energy term and the effect of the basis set superposition error on the geometry of the BF3⋯NH3 and C2H4⋯SO2 van der Waals dimers have been analyzed. Second-order Møller-Plesset perturbation theory calculations with the d95(d,p) basis set have been used to calculate the counterpoise-corrected barrier height for the internal rotations. These barriers have been obtained by relocating the stationary points on the counterpoise-corrected potential energy surface of the processes involved. The fragment relaxation energy can have a large influence on both the intermolecular parameters and barrier height. The counterpoise correction has proved to be important for these systems

Exchange-biased Ni/FeF2 films have been investigated using vector coil vibrating-sample magnetometry as a function of the cooling field strength HFC . In films with epitaxial FeF2 , a loop bifurcation develops with increasing HFC as it divides into two sub-loops shifted oppositely from zero field by the same amount. The positively biased sub-loop grows in size with HFC until only a single positively shifted loop is found. Throughout this process, the negative and positive (sub)loop shifts maintain the same discrete value. This is in sharp contrast to films with twinned FeF2 where the exchange field gradually changes with increasing HFC . The transverse magnetization shows clear correlations with the longitudinal subloops. Interestingly, over 85% of the Ni reverses its magnetization by rotation, either in one step or through two successive rotations. These results are due to the single-crystal nature of the antiferromagnetic FeF2 , which breaks down into two opposite regions of large domains.
