La razón práctica a partir del iuspersonalismo

In the present work I try to sketch the role that the practical reason in the legal field, based on iuspersonalism; since, from my point of view, it provides epistemological principles consistent enough to prevent the concept of legal rationality from collapsing, as it did in enlightened rationalism (positivism).En el presente trabajo pretendo esbozar el papel que juega la razón práctica en el ámbito jurídico, a partir del iuspersonalismo; ya que, desde mi punto de vista, aquélla provee principios epistemológicos lo suficientemente consistentes como para evitar que el concepto de racionalidad jurídica se colapse, como lo hizo en el racionalismo ilustrado (positivismo)

Alpine paleostress reconstruction and active faulting in western Iberia

The study of intraplate tectonics is crucial for understanding the deformation within plates, far from active plate boundaries and associated stress transmission to the plate interiors. This paper examines the tectonic evolution of the Variscan basement at the western margin of the Cenozoic Duero basin. Located east of the Vilariça Fault System in NW Iberia, this intraplate zone is a relatively flat but elevated area with an intense NNE-SSW trending fault system and associated moderate seismicity. Although the area has played an important role in the Duero basin configuration, its Alpine to present-day tectonic evolution has not been well constrained. In order to characterize the successive paleostress fields, 1428 pairs of fault-striae were measured at 56 sites and two focal mechanisms were used. Stress inversion methods have been applied to analyze paleostress regimes. Results show the existence of three dominant maximum horizontal stress (Shmax) trends: N-S, NE-SW and E-W. Relative and absolute dating of the activated faults for each Shmax shows that the clearly predominant N-S paleostress field in the zone has been active since the Oligocene up to the present day; while a NE-SW stress field is found to have been active during the Cretaceous and an older E-W paleostress field was active in the earlier Alpine cycle (Late Triassic)

Análisis de la fracturación y campos de paleoesfuerzos en el centrooeste de la Península Ibérica.

The Tormes Dome is a granitic massif emplaced during the Hercinian orogeny and later deformed by several posthercynian fracturation episodes. Three main paleostress fields have been obtained from stress inversion o f 1375 fault-slip data collected throughout the study area. The maximum horizontal stress (SHMAX) are oriented N-S, NE-SW and E-W with extensional and strike-slip stress regimes. Difficulties to determine age dating o f the three paleostress fields made necessary to enlarge the study area to the surrounding Cenozoic basins borders. In addition, geocronological information obtained form K-Ar dating o f fault gouges collected in the Tomes Dome has been used to establish the relative chronology of the three tectonic episodes from field data and determine their activity periods form Mesozoic to present time. An important result is that there is no relevant brittle tectonic activity associated with the recent NW-SE stress field in the western peninsula from Upper Miocene to the present times and some field evidences, as well as two focal mechanisms of earthquakes occurred in the area seem that in the Tormes Dome the recent stress field present an Shmax oriented N-S

Análisis cuantitativo de la fracturación tardihercínica en la Rama Aragonesa de la Cordillera Ibérica

From the e/K' diagram, the late-hercynian deformational regime is deduced in the Iberian Range Eastern branch. An evolution from reverse strike-slip tectonics to radial extension related to dyke emplacement (Hiendelaencina Phase) is proposed. Tejero R. y de Vicente, G.

Sistema inteligente de monitorización para la auscultación de tuberías mediante un robot

En este artículo se presenta el diseño, desarrollo e implementación de un sistema de monitorización para un robot de auscultación de tuberías en agujeros profundos. El cometido de estas tuberías es actuar como canalizaciones a la hora de inyectar materiales endurecedores del terreno, como paso previo a la realización de obras en infraestructuras subterráneas, como son los túneles. El diseño y la implementación de un sistema de monitorización tienen una serie de restricciones debido a su pequeño tamaño, condiciones de alta humedad y baja luminosidad. La tarea principal del sistema de monitorización es mejorar el seguimiento y localización del robot en el interior de tuberías de hasta 36 mm y realizar la monitorización mediante imágenes de modo que permita la trazabilidad de las labores realizadas en las infraestructuras. Para ello, en este trabajo se presenta el desarrollo de un sistema inteligente de visión e iluminación compuesto por una cámara de alta definición y un sistema de iluminación LED, el cual permite monitorizar el estado de la tubería y el recorrido llevado a cabo por el robot en el interior de la misma. Como corroboración experimental, los resultados serán comparados con los obtenidos mediante las mediciones realizadas con otro tipo de sensores, tales como inclinómetros, acelerómetros, etc. El robot ha sido probado en condiciones extremas realizando tareas de vigilancia y localización, obteniéndose unos resultados muy prometedores. El desarrollo de este robot pretende generar unas bases científicas y técnicas que ayuden a mejorar, e incluso sustituir, los sistemas comerciales existentes para la comprobación de la calidad y el cumplimiento de tolerancias en agujeros profundos para tuberías de poco diámetro llevados a cabo en obras para infraestructuras subterráneas, como son los túneles

Terminal interruption of relux source technique in the treatment of active venous ulcers

Introduction: The treatment for venous ulcers in most cases is unsatisfactory, with recurrences and poor healing. Objective: to evaluate adjuvant therapy in the treatment of active venous ulcers. Methods: We analyzed 20 patients with active venous ulcers attending the general Surgery outpatient clinic at the “Dr. José eleuterio gonzález” University Hospital from October 2012 to January 2013. they were randomly divided into 2 groups: group A (11 patients) underwent compression therapy and group B (9 patients) underwent compression therapy plus removal of the vein that gives terminal relux to the ulcer, guided by ultrasound (microphlebectomy). Patients were evaluated weekly (8 weeks). At each assessment, photographs and lesion measurements were taken and pain was evaluated using the visual analog scale. Results: No significant differences were found between the study groups in terms of age, weight, height, body mass index (BMi), ankle-brachial index, and baseline measurement of the ulcer (p>0.05). Group B showed a greater reduction in ulcer size and a statistically signiicant lower score on the visual analog pain scale (p<0.05) from the second and third week of treatment, respectively. Conclusions: the results obtained in patients with surgical procedure (group B) are consistent with the reported eficacy of chronic venous ulcer treatment with saphenectomy (conventional surgery), the difference is that in this study we used a minimally invasive procedure (microphlebectomy)

Similarities between recent seismic activity and paleoseismites during the late miocene in the external Betic Chain (Spain): relationship by ‘b’ value and the fractal dimension

A paleoseismic data set derived from the relationship between the thickness of seismites, ‘mixed layers’ in lacustrine Miocene deposits and the magnitude of the earthquakes is presented. The relationship between both parameters was calibrated by the threshold of fluidification limits in the interval of magnitude 5 and 5.5. The mixed layers (deformational sediment structures due to seismic activity) were observed in varved sediments from three Neogene lacustrine basins near Hellín (Albacete, Spain), El Cenajo, Elche de la Sierra and Híjar, and are interpreted as liquefaction features due to seismic phenomena. These paleoseismic structures were dated (relative values) by measurements of cyclic annual sedimentation in the varved sediments. From these observations, we are able to establish a recurrence interval of 130 years with events for magnitude bigger than or equal to four. Both paleoseismicity and instrumental seismicity data sets obey the Gutenberg–Richter law and the ‘b’ value is close to 0.86. The fractal dimension (dimension of capacity) of spatial distribution of potentially active faults (faults oriented according to the stress tensor regime in the area) was measured by the box-counting technique (D0 = 1.73). According to the Aki empirical relation (D0 = 2b ) for the instrumental seismicity and paleoseismic data sets in the area, the fractal dimension is close to 1.72. The similar value of the fractal dimension obtained by both techniques shows homogeneous seismic dynamics during the studied time interval. Moreover, the better stablished ‘b’ value of the paleoseismic data sets (0.86) compared with the ‘b’ value for the incomplete historic seismicity (<0.5) in the area increases the seismic series beyond the historic seismic record

Atraumatic maxillary sinus elevation using threaded bone dilators for immediate implants. A three-year clinical study

Objective: The aim of this study was to evaluate the efficacy of sinus floor elevation using sequential bone dilators. Materials and Methods: Thirty patients took part in the study (18 women and 12 men) with ages ranging between thirty-six and sixty-three years, selected according to inclusion and exclusion criteria, who showed a bone deficit in the upper posterior alveolar margin of 5-8 mm in height. Sixty expanded platform internal connection implants were placed with diameters of 4/5/4 mm and lengths varying between 10 (n=10) and 11.5 mm (n= 50). Results: Data obtained were analyzed using SPSS 15.0 software. The average intra-sinus bone gain with MP3 biomaterial of porcine origin was 4.13 +/- 0.97 SD mm at the moment of implant placement, 3.90 +/- 1.15 SD mm after twelve months, 3.74 +/- 1.05 SD mm after 24 months and 3.62 +/- 1.75 SD mm after 36 months. Two implants were lost at the moment of prosthesis placement. Conclusions: Alveolar lifting technique in the upper maxilla using bone dilators achieved a 96.6 % implant success rate after a three-year follow-up. Intra-sinus bone biomaterial remodeling was 0.51 +/- 0.08 mm from day zero to the thirty-six-month follow-up. This is a procedure that reduces the amount of surgery necessary and is of both aesthetic and functional benefit to the patient
