Geological patterns in the collapse of certain rock sanctuaries of Spain

Descripción de ciertos rasgos geológicos que amenazan el patrimonio religioso rupestre español. Rock sanctuaries are a historical heritage not as well-known as other religious constructions, due to their usual recondite location and abandoned condition. Spain has a large number of examples, mostly excavated during the Early Middle Age or even before. Fortunately, some of them are used on present worship, but the majority of these ancient shrines have suffered of severe damage through time, mostly due to common geological patterns. Some others threaten to collapse soon unless urgent remedial improvement is applied. Some examples at different locations are shown, reviewing their problems, which involve weathering, major rock cracks, soft rock pillars and others related to the defective site where they were located.

How much energy will your NGN consume? A model for energy consumption in next generation access networks: The case of Spain

The contribution to global energy consumption of the information and communications technology (ICT) sector has increased considerably in the last decade, along with its growing relevance to the overall economy. This trend will continue due to the seemingly ever greater use of these technologies, with broadband data traffic generated by the usage of telecommunication networks as a primary component. In fact, in response to user demand, the telecommunications industry is initiating the deployment of next generation networks (NGNs). However, energy consumption is mostly absent from the debate on these deployments, in spite of the potential impact on both expenses and sustainability. In addition, consumers are unaware of the energy impact of their choices in ultra-broadband services. This paper focuses on forecasting energy consumption in the access part of NGNs by modelling the combined effect of the deployment of two different ultra-broadband technologies (FTTH-GPON and LTE), the evolution of traffic per user, and the energy consumption in each of the networks and user devices. Conclusions are presented on the levels of energy consumption, their cost and the impact of different network design parameters. The effect of technological developments, techno-economic and policy decisions on energy consumption is highlighted. On the consumer side, practical figures and comparisons across technologies are provided. Although the paper focuses on Spain, the analysis can be extended to similar countries.

Uncertainty Analysis in New Seismic Hazard Study of Spain Aimed at the Revision of the Spanish Building Code.

In this paper we present a global overview of the recent study carried out in Spain for the new hazard map, which final goal is the revision of the Building Code in our country (NCSE-02). The study was carried our for a working group joining experts from The Instituto Geografico Nacional (IGN) and the Technical University of Madrid (UPM) , being the different phases of the work supervised by an expert Committee integrated by national experts from public institutions involved in subject of seismic hazard. The PSHA method (Probabilistic Seismic Hazard Assessment) has been followed, quantifying the epistemic uncertainties through a logic tree and the aleatory ones linked to variability of parameters by means of probability density functions and Monte Carlo simulations. In a first phase, the inputs have been prepared, which essentially are: 1) a project catalogue update and homogenization at Mw 2) proposal of zoning models and source characterization 3) calibration of Ground Motion Prediction Equations (GMPE’s) with actual data and development of a local model with data collected in Spain for Mw < 5.5. In a second phase, a sensitivity analysis of the different input options on hazard results has been carried out in order to have criteria for defining the branches of the logic tree and their weights. Finally, the hazard estimation was done with the logic tree shown in figure 1, including nodes for quantifying uncertainties corresponding to: 1) method for estimation of hazard (zoning and zoneless); 2) zoning models, 3) GMPE combinations used and 4) regression method for estimation of source parameters. In addition, the aleatory uncertainties corresponding to the magnitude of the events, recurrence parameters and maximum magnitude for each zone have been also considered including probability density functions and Monte Carlo simulations The main conclusions of the study are presented here, together with the obtained results in terms of PGA and other spectral accelerations SA (T) for return periods of 475, 975 and 2475 years. The map of the coefficient of variation (COV) are also represented to give an idea of the zones where the dispersion among results are the highest and the zones where the results are robust.

Perceived Health, Physical Activity and Sport among the Elderly of Spain

Purpose: It determines if participating in sports and/or physical activity influences perceived health among the elderly. Basic procedures: Data were drawn from a population subsample of subjects aged 65 - 79 years old that took part in a survey conducted in 2008 by the IESA-CSIC. A regression model was performed with perceived health status with the dependent variable and sociodemographic characteristics and physical activity as independent variables. Results: Physical activity is closely associated to per-ceived health, although sport has little influence on this relationship. Conclusions: Doing exercise or feeling that one is physically active makes the elderly feel better about their health status. However, this age group practises few sports and sport is not found to have an important or constant influence on self-perceived health status among the elderly.

Water, agriculture and ecosystem services in climate change vulnerable agricultural regions of Spain and Jordan

Irrigated agricultural landscapes generate a valuable set of ecosystem services, which are threatened by water scarcity in many aridand semi‐arid regions of the world. In the Mediterranean region, climate change is expected to decrease water availability through reduced precipitation and more frequent drought spells. At the same time, climate change, demographic and economic development and an agricultural sector highly dependent on irrigation, will raise water demand, increasing experienced water scarcity and affecting the provision of ecosystem services from water resources and agro-ecosystems. In this context, policy makers face the challenge of balancing the provision of different ecosystem services, including agricultural income and production and also water ecosystem protection.

Approach to the potential production of giant reed in surplus saline lands of Spain

Growing energy crops on marginal land has been promoted as a way of ensuring that biomass production involves an acceptable and sustainable use of land. Saline and saline-prone agricultural lands represent an opportunity for growing energy crops avoiding the displacement of food production and contributing to restoration of degraded land. Giant reed (Arundo donax L.) is a perennial grass that has been proposed as a promising energy crop for lignocellulosic biomass production while its tolerance to salinity has been proved. In this work, the identification of surplus saline lands that could be irrigated with saline waters for growing tolerant-energy crops (giant reed) in the mainland of Spain and the assessment of the agronomically attainable yield in these limiting growing conditions were undertaken. To this purpose, a GIS analysis was conducted using geodatabases related to saline areas, agro-climatic conditions, irrigation water requirements, agricultural land availability, restrictions regarding the range of electrical conductivity tolerated by the crop, competition with agro-food crops and irrigation water provisions. According to the approach developed, the irrigated and saline agricultural area available and suitable for biomass production from giant reed amounted up to 34 412 ha. The agronomically attainable yield in these limiting conditions was estimated at 12.7 – 22.2 t dm ha−1 yr−1 and the potential production of lignocellulosic biomass, 597 338 t dm yr−1. The methodology followed in this study can be applied to other target regions; it allows the identification of this type of marginal lands, where salinity-tolerant plant species could be grown for bioenergy purposes, avoiding competition with agro-food crops, and where soil restoration measurements should be undertaken.

How future trends may affect international cooperation in planning education : the case of Spain and Latin America

Despite the benefits for exc hanging experiences among planners at the global scale, the strong context dependency of urban planning creates in many instances significant difficulties to extrapolate experiences from one geographical context to the other. If progress is to be achieved in international cooperation programmes, differences and commonalities should be assessed before la unching any academic initiative. In that respect, this p aper makes a brief foresight exercise on how future trends and challenges, which may affect the urban pl anning field, should be taken into consideration according to two different contexts: Spain and Latin America. A segmentation matrix is used to expose a nd discuss the different effects of future trends on both contexts. Some tentative conclusions are drawn for the development of international educational programmes

Native bradyrhizobial symbionts of Lupinus mariae-josephae, a unique endemism thriving in alkaline soils in Eastern Spain

Lupinus mariae-josephae (Lmj) es una especie de lupino endémica de una pequeña y específica área de Comunidad Valenciana (Este de España), donde prospera en suelos alcalinoscalcáreos, un hábitat singular para los altramuces, que crecen preferentemente en suelos ácidos o neutros. Esto hace de Lmj una especie de lupino única. Cuando se inició este trabajo, la extensión conocida de este endemismo abarcaba unos 700 kilómetros cuadrados, confinados en la provincia de Valencia. En esta área, Lmj prospera en pequeñas poblaciones aisladas que contienen un número reducido de plantas por lo que se la consideró una especie en peligro de extinción. Todos los esfuerzos, utilizando estrategias clásicas dirigidas a ampliar el área de crecimiento de Lmj y garantizar su conservación, han tenido un éxito limitado. El trabajo que se presenta está dirigido a mejorar el conocimiento de la ecología de Lmj, en particular la interacción simbiótica que establece con bacterias del suelo denominadas rizobios y se centra en la caracterización fenotípica, filogenética y genómica de esos rizobios. También se investiga la posible contribución de la simbiosis en mejorar la conservación de Lmj. Para este fin, se han estudiado diferentes aspectos que se describen a continuación. El primero objetivo se centró en aislar y estudiar de la diversidad genética de las bacterias endosimbióticas de Lmj. . Se realizó un análisis filogenético de genes esenciales que mostró que las cepas de Lmj pertenecen al género Bradyrhizobium y que presentan una gran diversidad con características fenotípicas y simbióticas diferentes de cepas de Bradyrhizobium que nodulan otras especies de lupinos nativos de España (cepas ISLU). Las cepas estudiadas se dividieron en dos grupos (Clado I y Clado II). El Clado I, incluye a las cepas Lmj, definiendo un nuevo linaje, filogenéticamente relacionado con otras especies de Bradyrhizobium, como B. jicamae y B. elkanii. El Clado II contiene cepas ISLU relacionadas con cepas de B. canariense y B. japonicum que establecen simbiosis con lupinos de suelos ácidos. Otro análisis filogenético basado en genes simbióticos, distribuyó las cepas de Lmj en sólo dos grupos diferentes. La singularidad y gran diversidad de estas cepas en una pequeña área geográfica, hacen de este, un atractivo sistema para el estudio de la evolución y adaptación de las bacterias simbióticas a su respectiva planta huésped. Adicionalmente, se estudio la presencia de bacterias capaces de nodular Lmj en suelos básicos de Chiapas, México. Sorprendentemente, estos suelos contienen bacterias capaces establecer interacciones simbióticas eficientes con Lmj en ensayos de invernadero. A continuación se investigó la taxonomía de los endosimbiontes de Lmj analizando la secuencia de cuatro genes esenciales (16S rRNA, recA, glnII y atpD) y el promedio de identidad de nucleótidos de genomas completos de algunas cepas representativas de la diversidad (ANIm). Se identificaron nuevas especies de Bradyrhizobium dentro del Clado I y se definió una de ellas: 'Bradyrhizobium valentinum' sp. nov (cepa tipo LmjM3T = CECT 8364T, LMG 2761T). También se abordó cómo conservar Lmj en su hábitat natural mediante inoculación con alguna de las cepas aisladas. Se demostró la ausencia de bacterias capaces de nodular Lmj en suelos rojos alcalinos o ‘‘terra rossa’’ de la Península Ibérica y Baleares. Dos cepas, altamente eficientes en cuanto a la fijación de nitrógeno, LmjC y LmjM3T, fueron seleccionadas para ser empleadas como inoculantes. Dos experimentos de campo llevados a cabo en años consecutivos en áreas con características edafoclimáticas similares a las que presentan las poblaciones de Lmj, lograron la reproducción exitosa de la planta. Se concluyó que un ciclo reproductivo exitoso de Lmj es absolutamente dependiente de la inoculación con sus simbiontes naturales y que la simbiosis debe ser considerada un factor esencial en estrategias de conservación de leguminosas en peligro. La obtención de varias secuencias genómicas de cepas aisladas de Lmj y de otras cepas de Bradyrhizobium reveló una alta similitud entre los genomas de las cepas del Clado I, y permitió la identificación de cinco posibles nuevas especies. Además, se estudiaron tres agrupaciones de genes relacionados con la simbiosis (nod, nif y fix) definiendo un nuevo linaje para las cepas de Lmj, diferente del symbiovar “genistearum” de B. canariense y B. japonicum. La baja diversidad encontrada en el análisis filogenético de los genes simbióticos contrasta con la gran diversidad asociada a genes esenciales. La presencia de plásmidos en cepas del género Bradyrhizobium ha sido descrita en muy pocas ocasiones, sin embargo el análisis de la secuencia genómica de la cepa ISLU101, aislada de Lupinus angustifolius, reveló la presencia de un origen de replicación extracromosómico homólogo al operón repABC, presente en el plásmido de Bradyrhizobium sp BTAi1. Gracias a esta secuencia se identificaron genes homólogos en 19 de 72 cepas ISLU. Filogenéticamente, las secuencias de repABC se agruparon en un grupo monofilético con las de pBTAi1 y separadas de los rizobios de crecimiento rápido. Finalmente, se identificaron sistemas de secreción de proteínas de tipo III (T3SS) en nueve genomas de cepas de Lmj. Los T3SS pueden inyectar proteínas efectoras al interior de células vegetales. Su presencia en rizobios se ha relacionado con la gama de hospedador que pueden nodular y puede tener un efecto beneficioso, neutro o perjudicial en la simbiosis. Los T3SS de las cepas de Lmj codifican para una proteína efectora similar a NopE, un efector dependiente de T3SS descrito en B. diazoefficiens USDA 110T. La proteína NopE de la cepa LmjC se ha caracterizado bioquímicamente. ABSTRACT Lupinus mariae-josephae (Lmj) is a lupine species endemic of a unique small area in Valencia region (Eastern Spain) where the lupine plants thrive in alkaline-limed soils, which preferentially grow in acid or neutral soils. This is the type of soils native lupines of Spain. When this work was initiated, the extension of the endemic area of Lmj was of about 700 squared kilometers confined to the Valencia province. In this area, Lmj thrives in small, isolated patches containing a reduced number of plants, and points to an endemism that can easily became endangered or extinct. Consequently, the Valencia Community authorities gave a ‘‘microreserve” status for conservation of the species. All efforts, using classical strategies directed to extend the area of Lmj growth and ensure its conservation have been so far unsuccessful. The work presented here is directed to improve our knowledge of Lmj ecology and it is centered in the characterization of the rhizobial symbiosis by phenotypic, phylogenetic and genomic analysis as well as in investigate the potential contribution of the symbiosis to improve its conservation. To this end, five different topics have been studied, and results are briefly described here. Extensive details can be followed en the attached, published articles. The first topic deals with the indigenous rhizobial symbionts of the Lmj endemism, and its genetic diversity was investigated. The Lmj root symbionts belong to the Bradyrhizobium genus, and phylogenetic analysis based on core genes identified a large diversity of Bradyrhizobium strains with phenotypic and symbiotic characteristics different from rhizobia nodulating other Lupinus spp. native of Spain. The strains were split in two clades. Clade II contained strains close to classical B. canariense and B. japonicum lineages that establish symbioses with lupines in acid soils of the Mediterranean area. Clade I included Lmj strains that define a new lineage, close to other Bradyrhizobium species as B. jicamae and B. elkanii. The phylogenetic analysis based on symbiotic genes identified only two distinct clusters. The singularity and large diversity of these strains in such a small geographical area makes this an attractive system for studying the evolution and adaptation of the rhizobial symbiont to the plant host. Additionally, the presence of bacteria able to nodulate Lmj in basic soils from Chiapas, Mexico was investigated. Surprisingly, these soils contain bacteria able to effectively nodulate and fix nitrogen with Lmj plants in greenhouse assays. In the second topic, the taxonomic status of the endosymbiotic bacteria of Lmj from Valencia endemism and Chiapas was investigated. Results from phylogenetic analysis of core genes and Average Nucleotide Identity (ANIm) using draft genomic sequences identified new Bradyrhizobium species within strains of Clade I of Lmj endosymbiotic bacteria. Only one of these potentially new species has been defined, meanwhile the others are under process of characterization. The name ‘Bradyrhizobium valentinum’ sp. nov. was proposed for the defined species (type strain LmjM3T= CECT 8364T, LMG 2761T). The third topic was directed to conservation of endangered Lmj in its natural habitat. The relevant conclusion of this experimentation is that the symbiosis should be considered as a relevant factor in the conservation strategies for endangered legumes. First, we showed absence of bacteria able to nodulate Lmj in all the inspected ‘‘terra rossa’’ or alkaline red soils of the Iberian Peninsula and Balearic Islands. Then, two efficient nitrogen fixing strains with Lmj plants, LmjC and LmjM3T, were selected as inoculum for seed coating. Two planting experiments were carried out in consecutive years under natural conditions in areas with edapho-climatic characteristics identical to those sustaining natural Lmj populations, and successful reproduction of the plant was achieved. The relevant conclusion from these assays was that the successful reproductive cycle was absolutely dependent on seedling inoculation with effective bradyrhizobia The forth topic deep into the analysis of the genomic of Lmj representative strains. To this end, draft genomic sequences of selected Lmj strains and type strains of Bradyrhizobium spp. were assembled. The comparison analysis of the draft genomic sequences of Lmj strains and related Bradyrhizobium species grouped in Clade I, revealed a high genomic homology among them, and allowed the definition of five potentially new species of Lmj nodulating bacteria. Also, based on the available draft genomic sequences, only three clusters of nod, fix and nif genes from Lmj strains were identified and showed to define a new symbiotic lineage, distant from that of B. canariense and B. japonicum bv. genistearum. The low diversity exhibited by the phylogenetic analysis of symbiotic genes contrast with the large diversity of strains as regards the housekeeping genes analyzed. Besides, the genomic analysis of a Lupinus angustifolius strain ISLU101, revealed the presence of an extrachromosomal replication origin homologous to repABC cluster from plasmid present in Bradyrhizobium spp BTAi1. This repABC cluster gene sequence allowed the identification of extrachromosomic replication origin in 19 out of 72 Bradyrhizobium strains from Lupinus spp., a highly significant result since the absence of plasmids in the Bradyrhizobium genus was traditionally assumed. The repABC gene sequences of these strains grouped them in a unique monophyletic group, related to B. sp. BTAi1 plasmid, but differentiated from the repABC gene cluster of plasmids in fast growing rhizobium strains. The last topic was focused on characterization of type III secreted effectors present in Lmj endosymbiotic bacteria. Type III secretion systems (T3SS) are specialized protein export machineries which can deliver effector proteins into plant cells. The presence of T3SS in rhizobia has frequently been related to the symbiotic nodulation host-range and may have a beneficial or detrimental effect on the symbiosis with legumes. In this context, the presence of T3SS in genomes of nine Lmj strains was investigated, and it was shown the presence of clusters encoding NopE type III-secreted protein similar to the NopE1 and NopE2 of B. diazoefficiens USDA 110T. The putative NopE protein of LmjC strain is at present being characterized regarding its structure and function.

An educational initiative between the Universidad Politécnica de Madrid and Spanish Young Generation in Nuclear (Jóvenes Nucleares): The Seminar of Nuclear Safety in Advanced Reactors

Jóvenes Nucleares (Spanish Young Generation in Nuclear, JJNN) is a non-profit organization and a commission of the Spanish Nuclear Society (SNE). The Universidad Politécnica de Madrid (Technical University of Madrid, UPM) is one of the most prestigious technical universities of Spain, and has a very strong curriculum in nuclear engineering training and research. Finishing 2009, JJNN and the UPM started to plan a new and first-of-a-kind Seminar in Nuclear Safety focused on the Advanced Reactors (Generation III, III+ and IV). The scope was to make a general description of the safety in the new reactors, comparing them with the built Generation II reactors from a technical point of view but simple and without the need of strong background in nuclear engineering to try to be interesting for the most number of people possible.

Some past decision theory models for euro construction model codes and for road drainage in Spain, and modest hints with multi-criteria methods for agro and environmental assurance

The authors are from UPM and are relatively grouped, and all have intervened in different academic or real cases on the subject, at different times as being of different age. With precedent from E. Torroja and A. Páez in Madrid Spain Safety Probabilistic models for concrete about 1957, now in ICOSSAR conferences, author J.M. Antón involved since autumn 1967 for euro-steel construction in CECM produced a math model for independent load superposition reductions, and using it a load coefficient pattern for codes in Rome Feb. 1969, practically adopted for European constructions, giving in JCSS Lisbon Feb. 1974 suggestion of union for concrete-steel-al.. That model uses model for loads like Gumbel type I, for 50 years for one type of load, reduced to 1 year to be added to other independent loads, the sum set in Gumbel theories to 50 years return period, there are parallel models. A complete reliability system was produced, including non linear effects as from buckling, phenomena considered somehow in actual Construction Eurocodes produced from Model Codes. The system was considered by author in CEB in presence of Hydraulic effects from rivers, floods, sea, in reference with actual practice. When redacting a Road Drainage Norm in MOPU Spain an optimization model was realized by authors giving a way to determine the figure of Return Period, 10 to 50 years, for the cases of hydraulic flows to be considered in road drainage. Satisfactory examples were a stream in SE of Spain with Gumbel Type I model and a paper of Ven Te Chow with Mississippi in Keokuk using Gumbel type II, and the model can be modernized with more varied extreme laws. In fact in the MOPU drainage norm the redacting commission acted also as expert to set a table of return periods for elements of road drainage, in fact as a multi-criteria complex decision system. These precedent ideas were used e.g. in wide Codes, indicated in symposia or meetings, but not published in journals in English, and a condensate of contributions of authors is presented. The authors are somehow involved in optimization for hydraulic and agro planning, and give modest hints of intended applications in presence of agro and environment planning as a selection of the criteria and utility functions involved in bayesian, multi-criteria or mixed decision systems. Modest consideration is made of changing in climate, and on the production and commercial systems, and on others as social and financial.

Impact of the Economic Recession on Toll Highway Concessions in Spain

After joining the European Union in 1986, Spain experienced steady economic growth that enabled the country to grow at a greater pace than other European countries. During this period, the government of Spain opted for major investments in public infrastructure by taking advantage both of the funding provided by the European Union and of several types of public-private-partnership (PPP) approaches. Within this framework, the government of Spain between 1996 and 2004 procured a series of toll highway concessions. These concessions entered into operation a few years before the global economic recession made itself felt in Spain. The concession contracts signed between the government and some private consortia allocated most of the risks (expropriation, construction, and traffic) to the private sector. In this paper the impact that the economic recession has had on the business performance of the concessionaires is assessed, and the effectiveness of the measures adopted by the government to help the concessionaire to avoid bankruptcy is analyzed. It was found that some of the guarantees offered by the legal framework to the concessionaires in case of bankruptcy are prompting an outcome that could negatively affect the users. In addition to that, some suggestions as to how to better allocate risk in toll highway concessions in the future are provided.

Information as a Key Tool for Rural Development. 25 Years of Experience in Spain

The lack of useful information has become a major obstacle that hinders the participation of the members of the community in the development process because they can not accurately perceive how their individual and/or collective action can influence their environment, and because of the lack of elements that support the decision-making processes. This article addresses these issues from the work carried out by the Association Instituto de Desarrollo Comunitario de Cuenca (IDC Cuenca) in the rural areas of this province of Spain for 25 years. The results show how the application of methodologies for the transmission of information tailored to each group of recipients in some aspects, enhances the participation of individuals.
