Evolución de las aportaciones en embalses de cabecera del Guadalquivir: relación con las tendencias climáticas recientes y repercusión en la planificación hidrológica

Existen crecientes evidencias sobre la disminución de las aportaciones a embalses en diferentes cuencas de la Península Ibérica. Este hecho viene intensificando los indicios de sobrevaloración de las disponibilidades de agua estimadas por la planificación hidrológica. La actual Instrucción de la P.H., mejorada en su versión final (10 de septiembre de 2008) respecto de los borradores anteriores, establece la necesidad de tomar en consideración este riesgo, ordenando manejar las series de aportaciones más largas disponibles pero contrastándolas con las correspondientes al periodo 1980/81-2005/06, utilizando este último para establecer las asignaciones de recursos a los diferentes usos. Con este telón de fondo, en esta comunicación se analiza el tratamiento que la estimación de los recursos hídricos naturales y los posibles efectos sobre ellos del cambio climático viene teniendo en la documentación del nuevo plan hidrológico de la cuenca del Guadalquivir. A continuación se presentan las series de aportaciones de nueve embalses de cabecera de la cuenca del Guadalquivir, contrastando los datos derivados de las series históricas completas con los de las series más recientes, poniéndolas en relación con series zonales históricas de precipitaciones. Como conclusión, en la comunicación se confirma la importancia de la diferenciación establecida en la Instrucción, así como la urgencia de su incorporación en el proceso de planificación

Análisis y valoración del tratamiento del cambio climático en el proyecto de Plan Hidrológico de la demarcación del Guadalquivir

Desde el 15 de diciembre de 2010 se encuentra en información pública el borrador del plan hidrológico de la demarcación hidrográfica del Guadalquivir, etapa clave del proceso de planificación previsto por la Directiva Marco de Agua (DMA). En esta comunicación se presenta un análisis de los contenidos de este documento referidos al cambio climático: información climática manejada, tratamiento de las series de referencia, cuantificación de los recursos actuales y futuros, diferencias espaciales, consideración de la incertidumbre, etc. Se continúa así la línea de trabajo iniciada por los autores (Aguilar y Del Moral, 2008 y 2010) centrada en el seguimiento del tratamiento de las variaciones y tendencias climáticas, así como sus efectos sobre la estimación de los recursos hídricos naturales, en las anteriores etapas del proceso de planificación en el Guadalquivir. Los resultados confirman la importancia de la incorporación en el proceso de planificación de un análisis y consideración riguroso de la evaluación de los riesgos asociados al cambio climático, así como las grandes lagunas todavía existentes y el gran trabajo por realizar en este tema

The Capability Approach and Child Well-Being: A Systematic Literature Review

Child well-being is a dynamic concept currently under revision due to its complexity and the need to incorporate traditionally overlooked perspectives. An essential aspect of this revision is considering children as active agents in defining the concept itself and incorporating new elements that enrich the more traditional economics-based and adult-centred conceptualisation. In these regards, the capability approach (CA) provides valuable theoretical support for an expanded understanding of child well-being. Therefore, this article aims to offer a systematised review of the literature from the last two decades that uses this approach in examining children and childhood. To do so, the authors examined the main international databases and conducted relevant additional searches, identifying 63 journals that have published capabilitarian articles over the last two decades. Our findings show that most publications concentrate on recent years, with an expansion of the methodologies used and the contexts addressed. Although education seems to be one of the primary interests of this literature, there has also been an increasing range of children's realities and topics observed that we summarised in 10 categories. Between then, we dig deeper into the subsegment that specifically addresses the category of child well-being. Our review reveals that quantitative approaches and European contexts are predominant within these papers, and we analyse how they concern different spaces, well-being dimensions and intersectionalities

A well-being of their own: Children’s perspectives of well-being from the capabilities approach

Although children’s well-being is an increasingly important area of interest for policy and research, it is still an under-theorized concept. This article proposes a theoretical framework regarding children’s well-being that combines a capabilities approach with a social provisioning approach. The methodology used involved children in the conceptualization of their well-being and in validating a list of relevant capabilities necessary to have a good life. The data show how children express a multidimensional understanding of well-being and propose an agenda of priorities and concerns of their own different from that of adults.Junta de Adalucía, Consejería de Innovación, Ciencia y Universidad17 página

Expanding the etiology of oculo-auriculo-vertebral spectrum: a novel interstitial microdeletion at 1p36

The etiology of oculo-auriculo-vertebral spectrum (OAVS) is not well established. About half of patients show a positive family history. The etiology of familiar cases is unclear but appears genetically heterogeneous. This motivated us to report a case of OAVS with microtia, ptosis, facial microsomy, and fusion of vertebral bodies associated with a novel genetic etiology, including a deletion at 1p36.12-13. This case report expands on the genetic etiology of OAVS. Furthermore, it also expands the clinical manifestations of patients with interstitial deletions of the de 1p36.12-13 region

Tendencias climáticas recientes y evolución de las aportaciones en embalses de cabecera del Guadalquivir: su incidencia en la planificación hidrológica

Ponencia presentada en: VII Congreso de la Asociación Española de Climatología: clima, ciudad y ecosistemas, celebrado en Madrid entre el 24 y 26 de noviembre de 2010.[ES]Investigaciones recientes muestran que existen crecientes indicios acerca de la disminución de los recursos naturales en diferentes cuencas hidrográficas de la Península Ibérica. Este hecho viene confirmando la hipótesis de la sobrevaloración de las disponibilidades de agua estimadas por la planificación hidrológica. La actual Instrucción de la Planificación Hidrológica, mejorada en su versión final (10 de septiembre de 2008) respecto de los borradores anteriores, establece la necesidad de tomar en consideración este riesgo, recomendando manejar las series de aportaciones más largas disponibles pero contrastándolas con las correspondientes al periodo 1980/81-2005/06, utilizando este último para establecer los balances hidrológicos y las asignaciones de recursos a los diferentes usos.[EN]There is growing evidence of declining renewable water resources in different river basins in the Iberian Peninsula. This evidence further confirms the theory of overestimation of water availability for water planning. The current Spanish Water Planning Instruction, improved in its final version (10th September 2008) over earlier drafts, establishes the need to take into account this risk and recommends managing the longest series of inputs available but contrasting them with those for period 1980/81-2005/06, using the latter to establish the allocation of water resources to different uses.Proyecto de Investigación Fundamental no orientada 2009 “Efecto del calentamiento global sobre la concentración atmosférica de esporas en el suroeste de Andalucía, y su repercusión en las alergias respiratorias” CGL2009-10883.

Cost-Effective Force Field Tailored for Solid-Phase Simulations of OLED Materials

A united atom force field is empirically derived by minimizing the difference between experimental and simulated crystal cells and melting temperatures for eight compounds representative of organic electronic materials used in OLEDs and other devices: biphenyl, carbazole, fluorene, 9,9′-(1,3-phenylene)bis(9H-carbazole)-1,3-bis(N-carbazolyl)benzene (mCP), 4,4′-bis(N-carbazolyl)-1,1′-biphenyl (pCBP), phenazine, phenylcarbazole, and triphenylamine. The force field is verified against dispersion-corrected DFT calculations and shown to also successfully reproduce the crystal structure for two larger compounds employed as hosts in phosphorescent and thermally activated delayed fluorescence OLEDs: N,N′-di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine (NPD), and 1,3,5-tri(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl (TPBI). The good performances of the force field coupled to the large computational savings granted by the united atom approximation make it an ideal choice for the simulation of the morphology of emissive layers for OLED materials in crystalline or glassy phases.This work was supported by the Samsung Advanced Institute of Technology (SAIT)s Global Research Outreach (GRO) Program.

Nature (Hole or Electron) of Charge-Transfer Ability of Substituted Cyclopyrenylene Hoop-Shaped Compounds

We theoretically investigate here by means of DFT methods how the selective substitution in cyclic organic nanorings composed of pyrene units may promote semiconducting properties, analyzing the energy needed for a hole- or electron-transfer accommodation as a function of the substitution pattern and the system size (i.e., number of pyrene units). We choose to study both [3]Cyclo-2,7-pyrenylene ([3]CPY) and [4]Cyclo-2,7-pyrenylene ([4]CPY) compounds, the latter already synthesized, with substituents other than hydrogen acting in ipso and ortho positions, as well as the effect of the per-substitution. As substituents, we selected a set of electroactive halogen atoms (F, Cl, and Br) and groups (CN) to disclose structure–property relationships allowing thus to anticipate the use of these systems as organic molecular semiconductors.A.J.P.-J. and J.C.S.-G. acknowledge the project AICO/2018/175 from the Regional Government (GVA/FSE).

Intra- and Intermolecular Dispersion Interactions in [n]Cycloparaphenylenes: Do They Influence Their Structural and Electronic Properties?

Cycloparaphenylenes (CPPs) are nanosized structures with unique isolated and bulk properties, and are synthetic targets for the template-driven bottom-up synthesis of carbon nanotubes. Thus, a systematic understanding of the supramolecular order at the nanoscale is of utmost relevance for molecular engineering. In this study, it is found that intramolecular noncovalent (dispersion) interactions must be taken into account for obtaining accurate estimates of the structural and optoelectronic properties of [n]CPP compounds, and their influence as the number of repeat units increases from n=4 to n=12 is also analyzed, both in the gas phase and in solution. The supramolecular self-assembly, for which both intra- and intermolecular noncovalent interactions are relevant, of [6]CPP is also investigated by calculating the binding energies of dimers taken along several crystal directions. These are also used to estimate the cohesive energy of the crystal, which is compared to the value obtained by means of dispersion-corrected DFT calculations using periodic boundary conditions. The reasonable agreement between both computational strategies points towards a first estimate of the [6]CPP cohesive energy of around 50 kcal mol−1.This work is supported by the “Ministerio de Economia y Competitividad” of Spain and the “European Regional Development Fund” through projects CTQ2011-27253, CTQ2014-55073P and FIS2012-35880

Understanding and Controlling Chemical Modifications of Rubicene for Their Envisioned Use as Molecular Organic Semiconductors

We discuss here the relationship between the structure of a set of halogenated and cyanated molecules containing the rubicene moiety and a set of relevant electronic properties related to the optoelectronic and semiconductor character of these systems, namely, frontier molecular orbital shape and energy levels, electron affinity, ionization potential, reorganization energy, and electronic coupling between neighboring dimers, calculated over experimental (X-ray) or simulated crystal structures. To do it, we always employ accurate and validated density functional theory methods. The obtained results will be compared with some reference organic semiconductor systems, in order to determine the potential use of the studied compounds in the fabrication of optoelectronic devices.This work is supported by the “Ministerio de Economía y Competitividad” of Spain and the “European Regional Development Fund” through project CTQ2014-55073-P.
