Resumen: Ordo Virtutum es la única pieza dramático-musical de Hildegarda de Bingen, traducida generalmente en español como El drama de las Virtudes. Su composición –en lengua latina– data del año 1150 aproximadamente, durante la finalización de su primer libro visionario, el Scivias Domini o Conoce los caminos del Señor. Como figura del siglo XII con la particularidad del don visionario y familiarizada con el estilo de las Sagradas Escrituras, es posible considerar que el símbolo se haya convertido para Hildegarda en el medio más adecuado para poder expresarse. Y como mística, la correspondencia simbólica de múltiples lenguajes estéticos lleva a pensar en un trabajo de creación en el cual una sola de las expresiones no hubiera bastado. Desde el ámbito literario en diálogo con otras artes, en este trabajo observaremos cómo los símbolos provenientes de los lenguajes estéticos empleados por Hildegarda se corresponden y concuerdan, constelados, para ampliar el espectro de sentido de la obra.

Resumen: Los hallazgos de instrumentos musicales en entierros y cuevas de Santanderhan permitido reconstruir algunas de las características del arte musical Guane. El grupo de artefactos estudiado esta compuesto porocho quenas de caña, una quena de hueso, una ocarina de cerámica, una ocarina de caña, una zampoña de hueso y unas maracas; estos instrumentos son la única evidenciaen existencia de la práctica musical Guane más allá de los escritos realizados por los cronistas españoles, por lo que han sido estudiados y consignados aún cuando algunos presentan un avanzado estado de deterioro. El estudio acústico y la observación realizada con la aprobación de las instituciones en las cuales reposan estos artefactos han permitido obtenerinformación acerca de la organología, las técnicas de construcción y organización modal de los instrumentos, con lo cual se diluyen las nociones de una cultura musical caótica para dar paso al encuentro de los sistemas sonoros específicos utilizados por esta comunidad prehispánica.

Resumen: La conmemoración de los cien años de la Revolución de Mayo halló un país emergente en todo aspecto, inclusive en el cultural. De este modo, todos los músicos, nativos o argentinos por adopción, y aun extranjeros de paso o venidos para la ocasión, quisieron estar presentes con su actuación. No sólo por amor a un país que recién parecía tomar conciencia de su cultura, sino, al menos, para no desperdiciar una ocasión única de hacerse ver y notar. Es así que se produjeron una gran cantidad de eventos musicales, dignos de ser estudiados y recordados en el presente, en que se celebra un nuevo centenario, de modo de poder establecer las diferencias que se manifiestan entre uno y otro.

Knowledge of damage accumulation and corresponding failure evolution are prerequisite for effective maintenance of civil engineering so as to avoid disaster. Based on statistical mesoscopic damage mechanics, it was revealed that there are three stages in the process of deformation, damage and failure of multiscale heterogeneous elastic-brittle medium. These are uniformly distributed damage, localized damage and catastrophic failure. In order to identify the transitions from scattering damage to macroscopically localized one, a condition for damage localization was given. The experiments of rock under uniaxial compression with the aid of observations of acoustic emission and speckle correlation do support the concept of localization. This provides a potential approach to properly evaluate damage accumulation in practice. In addition, it is found in the experiments that catastrophic failure displays critical sensitivity. This gives a helpful clue to the prediction of catastrophic failure. (C) 2004 Elsevier Ltd. All rights reserved.

A mathematical model for the rain infiltration in the rock-soil slop has been established and solved by using the finite element method. The unsteady water infiltrating process has been simulated to get water content both in the homogeneous and heterogeneous media. The simulated results show that the rock blocks in the rock-soil slop can cause the wetting front moving fast. If the rain intensity is increased, the saturated region will be formed quickly while other conditions are the same. If the rain intensity keeps a constant, it is possible to accelerate the generation of the saturated region by properly increasing the vertical filtration rate of the rock-soil slop. However, if the vertical filtration rate is so far greater than the rain intensity, it will be difficult to form the saturated region in the rock-soil slop. The numerical method was verified by comparing the calculation results with the field test data.

The critical excavation depth of a jointed rock slope is an important problem in rock engineering. This paper studies the critical excavation depth for two idealized jointed rock slopes by employing a face-to-face discrete element method (DEM). The DEM is based on the discontinuity analysis which can consider anisotropic and discontinuous deformations due to joints and their orientations. It uses four lump-points at each surface of rock blocks to describe their interactions. The relationship between the critical excavation depth D-s and the natural slope angle alpha, the joint inclination angle theta as well as the strength parameters of the joints c(r) ,phi(r) is analyzed, and the critical excavation depth obtained with this DEM and the limit equilibrium method (LEM) is compared. Furthermore, effects of joints on the failure modes are compared between DEM simulations and experimental observations. It is found that the DEM predicts a lower critical excavation depth than the LEM if the joint structures in the rock mass are not ignored.

[EN]In the course of a sondage dug in the rock shelter of J3, in the Jaizkibel mountains (at the north-western tip of Guipúzcoa), the body of a adult man was located buried inside a shell midden. This shell midden had not been disturbed and presented internal stratigraphy features. In any case, the outer edge of the shell midden does show some interesting interdigitation with the adjacent habitational layers, with evidence of different stages of occupation. Within the shell midden itself, under the individual buried there, it was possible to observe layers without any ceramics, whereas the layers covering said individual included ceramic fragments. This individual has been dated to 8,300 BP and therefore corresponds to a Mesolithic context.

This is a student paper done for a University of California Berkeley Zoology class. Since UCB didn't have its own marine lab at the time, it rented space at Hopkins Marine Station where this work was done. Cadet Hand earned his Ph.D. from Berkeley and went on to become Director of the Bodega Marine Laboratory. Donald Putnam Abbott also earned his Ph.D. from Berkeley and later became a Stanford professor at Hopkins Marine Station. (PDF contains 26 pages)

Digital Speckle Correlation Method (DSCM) is a useful tool for whole field deformation measurement, and has been applied to analyze the deformation field of rock materials in recent years. In this paper, a Geo-DSCM system is designed and used to analyse the more complicated problems of rock mechanics, such as damage evolution and failure procedure. A weighted correlation equation is proposed to improve the accuracy of displacement measurement on a heterogeneous deformation field. In addition, a data acquisition system is described that can synchronize with the test machine and can capture speckle image at various speeds during experiment. For verification of the Geo-DSCM system, the failure procedure of a borehole rock structure is inspected and the evolution of the deformation localization is analysed. It is shown that the deformation localization generally initializes at the vulnerable area of the rock structure but may develop in a very complicated way.
