Effective and neutral stresses in soils using boundary element methods

The evaluation of neutral pressures in soil mechanics problems is a fundamental step to evaluate deformations in soils. In this paper, we present some results obtained by using the boundary element method for plane problems, describing the undrained situation as well as the consolidation problem

Grado de conocimiento de los familiares y/o cuidadores de pacientes que requieren reposo prolongado, para prevenir UPP

La permanencia prolongada en cama genera problemas y/o complicaciones a nivel respiratorio, dermatológico y músculo esquelético, entre otros, siendo este último las úlceras por presión (UPP) una de las complicaciones más frecuentes. que produce en la persona una pérdida de la resistencia y elasticidad tisular provocando isquemia tisular por una disminución en la irrigación sanguínea, en las zonas de presión a nivel de las prominencias óseas, lo cual resulta desfavorable para la recuperación del paciente. Un tiempo permanente en una misma postura más la misma presión que ejerce el cuerpo por la fuerza de gravedad, hace que haya una falta importante de circulación que puede evolucionar en este tipo de lesiones. Se debe actuar de forma continua para solucionar estas complicaciones, por ello el equipo de salud, como actividad interdisciplinaria tiene que intervenir en la educación del individuo, la familia y la comunidad, por lo que definimos a la educación como el proceso que tiene el individuo de desarrollar distinta capacidades para llevar a cabo autodeterminaciones en forma efectiva. El familiar y/o cuidador está ligado directamente y es el encargado, en forma conjunta con el personal de enfermería, de cuidar al paciente en todo proceso de hospitalización o en domicilio, es por ello que el siguiente trabajo de investigación apunta a detectar los conocimiento que tienen estos familiares de pacientes internados en sala común del Policlínico Atuel, de General Alvear, Mendoza, sobre los cuidados en la prevención y desarrollo potencial de ulceras por presión, basados en los tres pilares fundamentales la higiene, la alimentación-hidratación y la movilización, durante el mes de junio del año 2013.Fil: Álvarez, Emilce.

Compressed k2-Triples for Full-In-Memory RDF Engines

Current "data deluge" has flooded the Web of Data with very large RDF datasets. They are hosted and queried through SPARQL endpoints which act as nodes of a semantic net built on the principles of the Linked Data project. Although this is a realistic philosophy for global data publishing, its query performance is diminished when the RDF engines (behind the endpoints) manage these huge datasets. Their indexes cannot be fully loaded in main memory, hence these systems need to perform slow disk accesses to solve SPARQL queries. This paper addresses this problem by a compact indexed RDF structure (called k2-triples) applying compact k2-tree structures to the well-known vertical-partitioning technique. It obtains an ultra-compressed representation of large RDF graphs and allows SPARQL queries to be full-in-memory performed without decompression. We show that k2-triples clearly outperforms state-of-the-art compressibility and traditional vertical-partitioning query resolution, remaining very competitive with multi-index solutions.Comment: In Proc. of AMCIS'201

AC-DCFS: a toolchain implementation to Automatically Compute Coulomb Failure Stress changes after relevant earthquakes

We present an automated free software-based toolchain to obtain Coulomb Failure Stress change maps on fault planes of interest following the occurrence of a relevant earthquake. The system uses as input the focal mechanism data of the event occurred and an active fault database for the region. From the focal mechanism the orientations of the possible rupture planes, the location of the event and the size of the earthquake are obtained. From the size of the earthquake, the dimensions of the rupture plane are obtained by means of an algorithm based on empirical relations. Using the active fault database in the area, the stress-receiving planes are obtained and a verisimilitude index is assigned to the source plane from the two nodal planes of the focal mechanism. The obtained product is a series of layers in a format compatible with any type of GIS (or map completely edited in PDF format) showing the possible stress change maps on the different families of fault planes present in the epicentral zone. These type of products are presented generally in technical reports developed in the weeks following the occurrence of the event, or in scientific publications; however they have been proven useful for emergency management in the hours and days after a major event being these stress changes responsible of aftershocks, in addition to the mid-term earthquake forecasting. The automation of the calculation allows its incorporation within the products generated by the alert and surveillance agencies shortly after the earthquake occurred. It is now being implemented in the Spanish Geological Survey as one of the products that this agency would provides after the occurrence of relevant seismic series in Spain
