Geometría del contacto de las peridotitas de Sierra Alpujata con la sucesión de Sierra Blanca (Complejo Alpujárride, Zona Interna Bética)

The peridotites of Sierra Alpujata thrust to the north a formation of granitoid gneisses and the succession of Sierra Blanca. This structure led to the individualization of the unit of this name, and thus it is considered to crop out in a tectonic window. Nevertheless, on the western border of Sierra Alpujata the gneisses, in continuity with the formations of Sierra Blanca, are situated over the peridotites. This means that the Sierra Blanca does not crop out in a tectonic window, and that the peridotites, on the whole, are in fact situated in a lower position. This situation has important consequences for the age of their first exhumation and for the geological evolution and structure of the regionLas peridotitas de Sierra Alpujata cabalgan hacia el norte a una formación de gneises granitoides y a la sucesión de Sierra Blanca, lo que condujo a individualizar la unidad de este nombre y a considerarla como aflorante en una ventana tectónica. Sin embargo, en el borde occidental de Sierra Alpujata se observa que dichos gneises, en continuidad con las formaciones de Sierra Blanca, están situados sobre las peridotitas. Esto significa que Sierra Blanca no aflora en una ventana y que las peridotitas están realmente situadas en una posición inferior. Este rasgo tiene importantes consecuencias en lo que concierne a la edad de su primera exhumación y a la evolución y estructura de la regió

Ageing in the working population associated with obesity and cardiovascular risk parameters

Objective: The shift experienced in recent decades in developed countries, with an aging population, also affects the working population. This is associated with an increase in diseases such as obesity and cardiovascular risk. The objective of this study is to understand the relationship between aging in men and women with respect to obesity and cardiovascular risk in a working population. Materials and methods: A cross-sectional descriptive study was conducted on 389 workers in the chemical industry sector of the Autonomous Community of Murcia. The relationship between age and BMI, CUN BAE, and RCV SCORE in men and women was calculated. Results: In both sexes, people ≥ 50 years show a higher BMI and body fat percentage than those < 50 years with p <0.001. In the female population aged ≥ 50 years, an increase in body fat percentage is observed compared to those aged < 50 years with p <0.001. CUN BAE shows higher values in individuals aged ≥ 50 years in both sexes (p <0.001), being higher in women. The RCV SCORE in both sexes is low in the studied population, with no significant differences observed by sex and age. Conclusions: Significant differences are observed in workers aged ≥ 50 years in obesity, BMI, and CUN BAE. Therefore, in order to act in primary prevention and health promotion in obesity and RCV related to aging within companies, it is useful to include parameters such as: BMI, CUN BAE, and RCV SCORE in health surveillance protocols

Principales fallas activas de las Cuencas de Granada y Guadix-Baza (Cordillera Bética)

The Granada and Guadix-Baza Basins, the largest Neogene-Quaternary intramontane basins of the Betic Cordillera (southern Spain), undergo active deformation with an associated moderate level of seismic activity. This deformation is controlled by a NNWSSE compressive regime and an approximate orthogonal tensional regime. The compression produced N70ºE to E-W folds of several scales, the Sierra Nevada antiform being the largest one. The tension is accommodated mainly by NW-SE active normal faults, the most notable being the Baza Fault, in the Guadix-Baza Basin, and the Granada, Sierra Elvira-Dílar and Padul-Dúrcal Faults, in the Granada Basin. In addition, other active faults with different orientations also exist, such as the Alfahuara-Botardo and the Galera faults in the Guadix-Baza Basin, and the Huenes, Obéilar-Pinos Puente and N of Sierra Tejeda Faults in the Granada Basin. Moreover, in several sectors, the presence of orthogonal normal fault sets suggests alternating trends or even radial extension. Slip rates of these active faults, based on geologic markers, vary between 0.06 and 0.5 mm/year. Estimates for the maximum expected magnitude of earthquakes caused by these faults vary between MW 6.0 and 7.0. The N of Sierra Tejeda and the Baza Faults, the largest faults in the Granada and Guadix-Baza Basins, respectively, have the greatest seismic potential. They could cause events up to a magnitude of MW 6.5-7.0, although their reference earthquakes, computed for a return period of 475 years, are on the order of MW 5.0-5.5.Las Cuencas de Granada y Guadix-Baza, las mayores cuencas intramontañosas del Neógeno y Cuaternario de la Cordillera Bética (sur de España), experimentan una deformación activa y tienen asociada una actividad sísmica moderada. La deformación está controlada por una compresión NNO-SSE y una tensión aproximadamente perpendicular. La compresión ha formado pliegues de dirección N70ºE a E-O de muy diferentes tamaños, siendo el antiforme de Sierra Nevada el mayor. La tensión se acomoda sobre todo por fallas normales NO-SE, siendo las más notables de ellas la falla de Baza, en la cuenca de Guadix-Baza, y las de Granada, Sierra Elvira-Dílar y Padul-Dúrcal, en la cuenca de Granada. Además, existen otras fallas activas con diferentes orientaciones, tales como la de Alfahuara-Botardo y la de Galera en la cuenca de Guadix-Baza y las de Huenes, Obéilar-Pinos Puente y norte de Sierra Tejeda en la cuenca de Granada. Además, en varios sectores, la presencia de juegos de fallas ortogonales sugiere cambios en el elipsoide de esfuerzos e incluso una extensión radial. Las tasas de desplazamiento de estas fallas activas, calculadas a partir de marcadores geológicos, varían entre 0,06 y 0,5 mm/año. La estimación del potencial sísmico indica que la máxima magnitud esperable de los terremotos producidos por estas fallas varía entre MW 6,0 y 7,0. La falla del N de Sierra Tejeda y la de Baza, las mayores respectivamente en las Cuencas de Granada y Guadix-Baza, tienen el mayor potencial sísmico. Podrían causar eventos con magnitudes del orden de MW 6,5-7,0, aunque sus terremotos de referencia para un periodo de retorno de 475 años son del orden de MW 5,0-5,5.This work has been financed through projects TOPO-IBERIA CONSOLIDER-INGENIO (CSD2006-00041), CGL2010-21048, CGL-2011-29920, CGL2011-30153-C02-02, P09-RNM-5388 and the Junta de Andalucía groups RNM 370, RNM148 and RNM325

Kinematics and paleostresses in the Jebha-Chrafate transcurrent fault (northern Rif, Morocco)

The Jebha-Chrafate is an ENE-WSW sinistral major transcurrent fault of the Rif Cordillera, formed during the southwestwards emplacement of the Internal Zones on the Flysch units and the External Zones. The analysis of minor structures along the Jebha area indicates the activity of top to the SW low and high angle normal faults during the tectonic wedge emplacement. In addition, most of the kinematic indicators along the transcurrent fault zone point to a reactivation as dextral fault during the recent NW-SE Eurasia-Africa convergence and a final overprinting of normal faults during the late stages of relief uplif

3D-printing of metallic honeycomb monoliths as a doorway to a new generation of catalytic devices: the Ni-based catalysts in methane dry reforming showcase

Stainless-steel honeycomb monoliths (square cell-shape/230 cpsi cylinders) were 3D-printed and used as support of a Ni/CeO2-ZrO2 powder deposited by washcoating. The resulting catalysts were characterized by XRF, SEM-EDX and H-2-TPR, and tested in the dry reforming of methane reaction. In the 750-900 degrees C range, they showed competitive conversions (45-95%) and H-2/CO ratio (0.84-0.94) compared to cordierite honeycombs with same catalyst loading and geometric characteristics, but did not require activation time thanks to better heat transfer. Both structured catalysts were stable in prolonged TOS experiments. The bare metallic monoliths exhibited significant activity at 900 degrees C due to their intrinsic nickel content

El Neógeno del Valle de los Guájares (Cordillera Bética, Granada)

El estudio llevado a cabo sobre las características litoestratigráficas, el contenido faunístico y la edad de los materiales neógenos del Valle de los Guájares, pone de manifiesto la presencia de materiales del Serravallense y del Tortonense, además de los correspondientes al Plioceno (?) - Cuaternario. Las deformaciones de tales materiales se deben esencialmente a fracturas con saltos tanto horizontales como verticales, que controlaron en buena medida el relieve y la sedimentación. A partir de estos datos y de otros de carácter regional se aborda la evolución geológica del sector, posterior a la estructuración esencial de la Cordillera Bética durante el Mioceno inferior. A este respecto se pueden destacar dos fases deformacionales: una fase finiserravallense, responsable de algunas fallas inversas que afectan a las margas pelágicas serravallenses y a los materiales alpujárrides y, probablemente, también responsable del nacimiento de sistemas de fallas, las cuales podrían ya controlar la sedimentación; segunda fase intratortonense que produce discordancia angular entre los materiales tortonenses así como una nueva actividad, principalmente con desplazamientos verticales, de los sistemas de fallas previamente formados. Los materiales del Plioceno (?) - Cuaternario muestran igualmente evidencias de movimientos tectónicos recientes en los que prevalecen los desplazamientos verticales sobre los horizontales.The geological study, lead upon the lithostratigraphic characteristics, the faunistic content and the age of the neogene materials from the Guájares valley reveals the presence of terranes belonging to the Serravallian and the Tortonian, besides the ones corresponding to the Pliocene (?) - Quaternary. The deformation features of such materials are essentially due to faults showing both horizontal and vertical slips, which strongly controlled the relief and the deposition. From these data and others of regional character we envisage the geological evolution of the area, once the main structuration of the Betic Cordilleras during the lower Miocene was already accomplished. In this regard two deformational phases stand out: a finiserravallian phase, responsible for sorne reverse faults concerning serravallian pelagic marls and alpujarride materials and, probably also and for the birth of important fault systems which could already control the sedimentation; which a second one, the intratortonian phase, which yields an angular unconformity within the tortonian materials as well as a new activity, mainly with vertical displacements, of the previous fault systems. The Pliocene (?)- Quaternary deposits provide also evidence of recent tectonic movements, the vertical slips being prevalent over the horizontal ones.Trabajo realizado dentro del Proyecto «El Borde Mediterráneo español: Evolución del Orógeno bético y geodinámica de las depresiones neógenas», realizado por el Departamento de Investigaciones Geológicas, C.S.I.C. y financiado por C.A.I.C.YT. y C.S.I.C

Ultrathin Washcoat and Very Low Loading Monolithic Catalyst with Outstanding Activity and Stability in Dry Reforming of Methane

A Ni/CeO2/ZrO2 catalyst with improved redox properties has been washcoated onto a honeycomb cordierite monolith in the form of a nonconventional alumina-catalyst layer, just a few nanometers thick. In spite of the very low active phase loading, the monolith depicts outstanding performance in dry reforming of methane, both in terms of activity, with values reaching the thermodynamic limit already at 750 degrees C, even under extreme Weight Hourly Space Velocities (WHSV 115-346 Lg(F -1)h(-1)), as well as in terms of stability during prolonged Time on Stream (TOS 24-48 h)
