Se presenta en este articulo la descripcion de la estructura para el cruce de las lineas de alta velocidad Madrid - Volencla y Madrid - Albacete en e termino municipal de Motilla del Palancar. Al soportar la pergola una linea de alta velocidad, fue necesario para su concepcion, un estudio detallado del comportamiento global. con objeto de adecuar la solucion habitual a los particularidades de la cargos a resistir. El resultado es una estructura con una cuidada estetico y un comportamiento funcional adecuado. EnglishThe junctions in spliltl evel with a small skew angle are usually solved by type pergola structures because they permit me resolution of the junction with a shorter span. This article shows the description of the structure for the crossing of the high speed lines Madrld - Valencia and Madrid - Albacete in the municipality of Motilla del Palancar. As the pergola supports a high speed rail. it was necessary to do detalled studies of the global behaviour since the beginning, in order to adequate the typicai structural solution to the particularities of the loads to resist. The result is o good aesthetical structure with an adequate functional behaviour.

Espana participa en esta ultima exposicion universal del milenio con la intencion declarada de "sorprender y de romper la imagen topica que se tiene del pais en el extranjero". Una de las claves en este empeno ha sido el diseno del propio pabellon, obra de los arquitectos sevillanos Cruz y Ortiz, cuya estructura, desmontable y reutilizable, presenta un buen ejemplo de innovacion basada en criterios de sostenibilidad.

Se muestran diversos sistemas longitudinales, viga continua, pórtico, arco o estructuras atirantadas. También en sentido transversal existe una gran variedad de soluciones, adaptando la sección de un puente o de una pasarela a las circunstancias particulares de cada caso. Por último, las posibilidades que brindan los procesos de montaje de la estructura metálica y el posterior hormigonado de la losa incrementan más todavía el atractivo de la solución mixta para las pasarelas y los puentes, especialmente en los casos con exigentes condiciones de borde.

Optimality Theory explains the conflict between the three restraints, Maxµ, which disfavors the deletion of an underlying mora, the obligatory contour principle, which disfavors double consonants, and *Coda, which disfavors coda consonants. Maxµ dominates and accommodates the surfacing of an underlying mora by lengthening the consonant following the initial aWhile le this is a word-formation process, the theory is based on a Neapolitan syntactic process, phono-syntactic reduplication.

This new algorithm uses a line segment as prototype which captures the axis that presents the biggest variance of the cluster. The line segment adjusts iteratively its long and direction as the data are classified. To perform the classification, a border region that determines approximately the limit on the cluster is built based on geometric model, which depends on the central line segment. The data are classified later according to their proximity to the different border regions. The process is repeated until the parameters of the all border regions associated with each cluster remain constant.

En esta investigación, se ha valido del programa S.P.S.S. para cruzar las respuestas del uso pronominal con las variables sociales de género, estado civil, edad, ingresos, estudios y provincia de nacimiento. La forma de tratamiento no-marcada en todas las situaciones estudiadas es el pronombreusted, tanto en ámbitos de solidaridad (familiaridad, amistad y confianza) como en los de distanciamiento y de poder. Los encuestados indican el empleo delvos, siempre la forma marcada y de uso minoritario, en ciertas relaciones de confianza y amistad, por ejemplo, con miembros de la familia, amigos y, a veces, con compañeros de trabajo. La prueba chi-cuadrado de Pearson muestra una dependencia significativa entre el empleo delvosen contextos de confianza y las variables independientes de género y edad. E...

The social variables considered were age, level of education, time in the USA and Utica, gender and generation. The latter two most influenced reported language selection. The participants overwhelmingly answered that they used Spanish during their childhood with parents and grandparents. However, comparing the participants' reported language use between childhood and adulthood, the parent-child and grandparent-grandchild relationships showed the largest decreases in reported use of Spanish among all the family relationships. This result is consistent with language shift to English in the family. The informants also report less exclusive use of Spanish with friends in adulthood than in childhood. However, 78 % of them said that they use both English and Spanish with friends in adulthood. In the forma...

These poems, dating from the 11th to the 14th centuries, were composed in Classical Arabic, while the kharjas were written in two languages of Al-Andalus: Andalusian Arabic and Romance. The purpose is to investigate to what degree the structural aspect of code-switching in the kharjas conforms to descriptions in the current literature on code-switching in bilingual communities and what that tells us about the degree of bilingualism in Al-Andalus. The 43 kharjas (Corriente, 2008) present a total of 104 code-switches: 82 intra-sentential, 13 word-internal and 9 inter-sentential. The base language in the majority of cases is Romance: 73 % of the switches occurred from Romance to Arabic. Cross- tabulations of the direction of the switch, lexical category of the switched parts and what immediately precedes and follows them show statistically significant r...

Students answered a questionnaire and chose the two main reasons from 10 choices articulated in sentimental, value, instrumental, and communicative dimensions. Cross-tabulations by SPSS showed significant statistical relationships between the attitudinal factors and the language studied. Spanish students strongly favored an instrumental orientation for both first and second choices. Danish, Dutch, French, Arabic, Russian, and German students also indicated instrumental preferences, but their second choices fell into other domains. Portuguese, Italian, Hebrew, Japanese, and Korean students favored communication factors, while Chinese students selected sentimental and communication reasons for their first and second choices, respectively.
