Stark Broadening of Sn III Spectral Lines of Astrophysical Interest: Predictions and Regularities

The determination of the Stark broadening parameters of Sn ions is useful for astrophysicists interested in the determination of the density of electrons in stellar atmospheres. In this paper, we report on the calculated values of the Stark broadening parameters for 171 lines of Sn iii arising from 4d105sns (n= 6–9), 4d105snp (n= 5, 6), 4d105p2, 4d105snd (n= 5–7), 4d105s4f and 4d105s5g. Stark linewidths and line shifts are presented for an electron density of 1023 m−3 and temperatures T= 11 000–75 000 K. These have been calculated using a semi-empirical approach, with a set of wavefunctions obtained from Hartree–Fock relativistic calculations, including core polarization effects. The results obtained have been compared with available experimental data. These can be used to consider the influence of Stark broadening effects in A-type stellar atmospheres

Diffuse Soil Co2 Flux To Assess The Reliability Of Co2 Storage In The Mazarrón-Gañuelas Tertiary Basin (Spain)

Geological storage of CO2 is nowadays internationally considered as the most effective method for greenhouse gas emission mitigation, in order to minimize its effects on the global climatology. One of the main options is to store the CO2 in deep saline aquifers at more than 800 m depth, because it achieves its supercritical state. Among the most important aspects concerning the performance assessment of a deep CO2 geological repository is the evaluation of the CO2 leakage rate from the chosen storage geological formation. Therefore, it is absolutely necessary to increase the knowledge on the interaction among CO2, storage and sealing formations, as well as on the flow paths for CO2 and the physico-mechanical resistance of the sealing formation. Furthermore, the quantification of the CO2 leakage rate is essential to evaluate its effects on the environment. One way to achieve this objective is to study of CO2 leakage on natural analogue systems, because they can provide useful information about the natural performance of the CO2, which can be applied to an artificial CO2 geological storage. This work is focused on the retention capacity of the cap-rock by measuring the diffuse soil CO2 flux in a site selected based on: i) the presence of a natural and deep CO2 accumulation; ii) its structural geological characteristics; and iii) the nature of the cap-rocks. This site is located in the so-called Mazarrón-Gañuelas Tertiary Basin, in the Guadalentin Valley, province of Murcia (Spain) Therefore the main objective of this investigation has been to detect the possible leakages of CO2 from a deep saline aquifer to the surface in order to understand the capability of this area as a natural analogue for Carbon Capture and Sequestration (CCS). The results obtained allow to conclude that the geological sealing formation of the basin seems to be appropriate to avoid CO2 leakages from the storage formation.

Effect of fibers and whole grain content on quality attributes

Incorporation of fiber in cereals may lead to quality issues, thus decreasing consumer acceptance. This is partially due to deterioration of the microstructure, one of the primary quality attributes of cereals. The objective of this study was to better understand the mechanisms by which dietary fibers affect the quality of cereal products during extrusioncooking. The study quantified the effect of amount and type of fiber and whole grain on (i) texture, (ii) structure, and (iii) rehydration properties of extruded cereals. New innovative methods were applied and combined with traditional techniques to characterize both the structure and the rehydration properties. Extruded cereals were produced using a starch-based recipe (whole and wheat flours) and two sources of fibers (oat bran concentrate and wheat bran). The oat and wheat bran levels used in this study were 0, 10, and 20%. The different mixtures were extruded in a pilot twinscrew extruder BC21 (Clextral) and then sugar coated after drying. Mechanical properties of extruded cereals were investigated by compression test. The cellular structure was observed by X-ray tomography. The quality of coating (thickness, homogeneity) was analyzed by optical coherence tomography. The rehydration properties of such cereals in milk were evaluated by magnetic resonance imaging and optical coherence tomography. This work revealed that structure assessment of extruded cereals may lead to a better understanding of the effect of fiber addition on texture and rehydration properties. The application of innovative methods, such as optical coherence tomography and magnetic resonance imaging, was found to be useful to quantify the structural properties.

Cooperative localization in mobile networks using nonparametric variants of belief propagation

Of the many state-of-the-art methods for cooperative localization in wireless sensor networks (WSN), only very few adapt well to mobile networks. The main problems of the well-known algorithms, based on nonparametric belief propagation (NBP), are the high communication cost and inefficient sampling techniques. Moreover, they either do not use smoothing or just apply it o ine. Therefore, in this article, we propose more flexible and effcient variants of NBP for cooperative localization in mobile networks. In particular, we provide: i) an optional 1-lag smoothing done almost in real-time, ii) a novel low-cost communication protocol based on package approximation and censoring, iii) higher robustness of the standard mixture importance sampling (MIS) technique, and iv) a higher amount of information in the importance densities by using the population Monte Carlo (PMC) approach, or an auxiliary variable. Through extensive simulations, we confirmed that all the proposed techniques outperform the standard NBP method.

Theory of intermittency applied to classical pathological cases

The classical theory of intermittency developed for return maps assumes uniform density of points reinjected from the chaotic to laminar region. Though it works fine in some model systems, there exist a number of so-called pathological cases characterized by a significant deviation of main characteristics from the values predicted on the basis of the uniform distribution. Recently, we reported on how the reinjection probability density (RPD) can be generalized. Here, we extend this methodology and apply it to different dynamical systems exhibiting anomalous type-II and type-III intermittencies. Estimation of the universal RPD is based on fitting a linear function to experimental data and requires no a priori knowledge on the dynamical model behind. We provide special fitting procedure that enables robust estimation of the RPD from relatively short data sets (dozens of points). Thus, the method is applicable for a wide variety of data sets including numerical simulations and real-life experiments. Estimated RPD enables analytic evaluation of the length of the laminar phase of intermittent behaviors. We show that the method copes well with dynamical systems exhibiting significantly different statistics reported in the literature. We also derive and classify characteristic relations between the mean laminar length and main controlling parameter in perfect agreement with data provided by numerical simulations

Optimisation of a Low-Speed Wind Tunnel. Analysis and Redesign of Corner Vanes.

This paper includes the experimental study, analysis, redesign and subsequent test of the parts of a closed circuit, low speed wind tunnel which are relevant in terms of total pressure loss. The objective is to lower the energy consumption of this system for given conditions in test chamber, so as to reduce the operational costs. In order to achieve this objective, several tasks were performed as the text shows in its different parts. For these tasks, the ETSIAE wind tunnel was used, although the results of this work can be extrapolated to any wind tunnel with the same characteristics. Part II presents a theoretical previous study of the general running of a closed circuit, low speed wind tunnel, as well as the followed procedure to conduct experimental tests for obtaining the total pressure loss in its parts. Results from these tests and their analysis are included in this part. In part III, the analysis of the influence of corner 1 on the pressure loss takes place. As it is said in this part, corner 1 has great importance in the total pressure loss of the wind tunnel. Therefore, it is the first part that should be modified in order to improve the performances of the wind tunnel. During part IV, an optimised guide vane is designed in order to reduce the pressure loss in corner 1 of the wind tunnel. Software MISES is used to achieve this goal by means of selecting the optimum guide vane. In order to introduce the new guide vane in wind tunnels with affordable costs, the easily constructable criterion is kept during design. For this reason, the guide vane will consist of simple aerodynamic contours. Part V includes some possible improvements for the proposed guide vane, in order to evaluate if there is room for improvement in its design. Finally, part VI includes the tests that were conducted in the wind tunnel with the new guide vane cascade and the analysis of their results, in order to asses whether the proposed design fulfills the requirement of lowering the total pressure loss in the wind tunnel. Part VII gathers the main ideas resulting from the whole work.

Influence of gravity on heavy particle statistics in turbulent channel and pipe flow at matched Kàrmàn number

In this work, we use large eddy simulations (LES) and Lagrangian tracking to study the influence of gravity on particle statistics in a fully developed turbulent upward/downward flow in a vertical channel and pipe at matched Kàrmàn number. Only drag and gravity are considered in the equation of motion for solid particles, which are assumed to have no influence on the flow field. Particle interactions with the wall are fully elastic. Our findings obtained from the particle statistics confirm that: (i) the gravity seems to modify both the quantitative and qualitative behavior of the particle distribution and statistics of the particle velocity in wall normal direction; (ii) however, only the quantitative behavior of velocity particle in streamwise direction and the root mean square of velocity components is modified; (iii) the statistics of fluid and particles coincide very well near the wall in channel and pipe flow with equal Kàrmàn number; (iv) pipe curvature seems to have quantitative and qualitative influence on the particle velocity and on the particle concentration in wall normal direction.

Balancing management and preservation of mediterranean scattered oak woodlands (Dehesas) in human-dominated landscapes

Los sistemas agroforestales mediterráneos tienen una gran importancia ecológica y socioeconómica, y mantienen altos valores medioambientales y de diversidad biológica a la vez que producen importantes servicios ecosistémicos. Estos sistemas han sido testigos de diversos cambios rápidos y drásticos en su gestión y aprovechamiento durante el último siglo. La mayor parte de la investigación desarrollada en esta tesis doctoral ha sido llevada a cabo en las dehesas españolas. Esta tesis nos muestra: i) la evidencia de la existencia de un cambio global del estrato arbóreo y del manejo del pastoreo en el todo el área de distribución de la dehesa durante los últimos 60 años; ii) la importancia del papel que juega el arbolado disperso y el adecuado manejo del ganado en la mejora de la producción, calidad y diversidad de las comunidades herbáceas, que a su vez, un pasto herbáceo bien desarrollado es importante para la rentabilidad del sistema, evaluando estos efectos bajo distintos escenarios de clima y calidad de estación; y iii) la evidencia de la falta de regeneración en sistemas agroforestales mediterráneos bajo distintos tipos de manejo del pastoreo, y además se evalúa el crecimiento y desarrollo de las pocas plántulas existentes que serán las que aseguren la viabilidad y persistencia y de estos sistemas. El arbolado disperso de estos sistemas ha experimentado una reducción importante en su densidad arbórea y fracción de cabida cubierta durante el periodo entre 1950-1980 donde tuvieron lugar importantes transformaciones en la actividad agropecuaria. La cabaña ganadera de ovino disminuyó drásticamente en los años 70 en comparación a la de bovino que desde entonces ha aumentado progresivamente hasta la actualidad. Por otro lado, el mismo tipo de manejo del ganado doméstico (especialmente bovino) durante bastante tiempo (mínimo 30 años) provocó una reducción significativa de la densidad de las plántulas. Además la probabilidad de ocurrencia y la intensidad de daños por herbivoría fue mayor bajo pastoreo bovino (con daños más intensos y consistentes) que bajo pastoreo ovino o sin pastoreo doméstico (presencia de ciervos). También el patrón de crecimiento de las plantas jóvenes estuvo afectado por el tipo de manejo, generando plántulas achaparradas en el caso del bovino y plántulas esbeltas favoreciendo el crecimiento en altura en el caso del ovino. La presencia de un arbolado disperso generó una mayor diversidad y variación en la producción de las comunidades herbáceas según las condiciones de disponibilidad de agua. Especialmente, el ecotono como microhábitat sostuvo altos valores de diversidad herbácea. La presencia del ganado bajo pastoreo continuo de intensidad moderada a alta, especialmente el bovino, incrementó los rendimientos de producción y diversidad del estrato herbáceo. Los resultados de esta tesis nos muestran la importancia que tiene la existencia de un equilibrio entre la producción y la conservación de los sistemas agroforestales mediterráneos para obtener una producción sostenible de servicios ecosistémicos mientras se asegura la perpetuación del sistema a largo plazo. Es crucial diseñar planes de gestión incorporando objetivos de conservación que integren técnicas silvopastorales apropiadas para poder aplicar en los sistemas agroforestales mediterráneos. ABSTRACT Mediterranean scattered oak woodlands have great ecological and socio-economic importance, supporting high environmental and amenity values, and relatively rich biological diversity while producing important ecosystem services. They have been witnesses of different and fast changes developed in the last century. Most of the research developed in this dissertation has conducted within dehesas. This thesis provides: i) the global change evidence of the tree layer and grazing management experienced in the land-use range of a Mediterranean scattered oak woodland (dehesa) over the last 60 years; ii) the important role of scattered trees and adequate management grazing in the improvement of grassland yield, quality and diversity - which it is important, in turn, for the system profitability - under different climate scenarios and site quality; and iii) the lack of oak regeneration evidence under some given representative management regimes and how is the growth development of these plants to assure the viability and persistence of Mediterranean scattered oak woodlands. Tree layer experienced a significant reduction in dehesas during 1950-1980 period where the highest human impacts took place. Sheep herd decreased drastically during the 1970s and, in contrast, cattle have been increasing gradually since then. On the other hand, same livestock grazing management (especially cattle) during long time (minimum 30 years) within Mediterranean scattered oak woodlands reduced strongly the density of young oak plants and showed high probability of herbivory occurrence and intensity. Young plant growth pattern was greatly modified by livestock. Cattle grazing generated stunted plants and sheep grazing generated slender plants favoring the height growth. Microsites created by large trees modified the herbaceous yield according the water availability of the year and generated high plant diversity within herbaceous communities. Especially, ecotone microsite supported high values of herbaceous diversity. The presence of livestock species increased the herbaceous yield and maintained a more diverse community under continuous grazing at both moderate and high intensities; especially cattle. Thus, around the influence of scattered trees there is a high amount of different interactions among livestock, trees and grasslands maintaining and enhancing the quality of whole dehesa system. The results of this thesis highlight how important is balancing management and preservation of Mediterranean scattered oak woodlands to obtain the optimum ecosystem services while the system conservation is assured for a long-term. It is crucial to design management plans with conservation goals that include appropriate silvopastoral practices in Mediterranean scattered oak woodlands.

La forma del agua. Temas e invariantes en el jardín y el paisaje. Análisis de casos (Holanda-España, 1548-1648)

El espacio geográfico, entendido como territorio que da soporte a la vida y a la civilización, ha estado siempre fuertemente supeditado a la presencia de agua. Desde la Prehistoria el hombre otorgó al agua, junto a otros elementos que aseguraban o protegían su vida, un valor superior, por encima de lo humano. Paralelamente y de manera natural, el jardín, en sus inicios en estrecha relación con la agricultura y con el paisaje, fue el ámbito idóneo para la creación de nuevas formas acuáticas artificiales. Este proceso dio lugar a un extenso repertorio de formas compositivas que parece que tuvo en el Renacimiento un punto de inflexión, en el que se observa como la mayoría de recursos y configuraciones básicas del agua estaban ya plenamente establecidas. Esta evolución y sus resultados ha sido el objeto de la primera parte de la tesis: su objetivo ha sido analizar cómo el agua configura, cualifica o puede llegar a construir el jardín y el territorio en el que se inserta, así como establecer las posibles relaciones entre estos dos ámbitos de estudio. Aunque la historia es su fundamento, el planteamiento aquí ha sido más bien conceptual; estudiando los componentes acuáticos desde un punto de vista fundamentalmente compositivo. Esta indagación previa ha sido indispensable para llegar a entender en profundidad los modos en los que el agua se muestra en el jardín y en el paisaje renacentista y manierista, momentos en que se insertan los dos casos de estudio que constituyen la segunda parte de la tesis. Sin caer en un determinismo geográfico extremo, puede admitirse que el jardín, como manifestación cultural intrínsecamente ligada al entorno, depende fuertemente del territorio en el que se asienta; hecho particularmente evidente en aquellas regiones en las que su especial geografía ha sido un claro factor condicionante de su historia. Por ello, Holanda y España han sido las dos localizaciones elegidas para profundizar en este estudio; no tanto por su estrecha relación política y cultural, sino por su profundo y sugerente contraste de medio físico y climático. La Península Ibérica, geográficamente el término del mundo conocido en Occidente hasta el final de la Edad Media, y por esta circunstancia convertida en destino, en territorio de permanencia y fusión, estará además supeditada en la mayoría de su territorio a la falta de agua, siendo a la vez heredera directa del universo y la tradición del jardín meridional originario de Oriente. En el extremo opuesto, Holanda, espacio de transición entre el mar y la tierra firme “real”, es un territorio permeado de humedad y surcado con generosidad por grandes ríos. El país, con una relación ambivalente con el agua, unas veces como amenaza y otras como fuente de nuevas oportunidades, será por el contrario especialmente favorable para el desarrollo de un modelo de jardín septentrional. Un jardín del norte, que no obstante, no surgirá de despejar los bosques, como en el arquetipo nórdico, sino que crecerá sobre planicies antes saturadas de agua o directamente anegadas. El marco temporal de los dos casos concretos ha considerado como fecha inicial 1548, momento en el que Felipe II, aún príncipe, realizó su primer viaje a los Países Bajos, y entró en contacto con el modelo holandés. La extensa producción posterior de jardines de Felipe II, siempre con el agua como protagonista, tuvo como destacado referente la adaptación al suelo y la geografía hispánicos de dicho modelo. Como fecha final se fija 1648, justo un siglo después, fecha coincidente con la firma de la Paz de Westfalia, tratado que supone la total reorganización política del territorio europeo y la pérdida de la hegemonía española en Europa. En Holanda sólo dos años después nacerá Guillermo III de Orange, estatúder de las Provincias Unidas, también futuro rey de Inglaterra, Escocia e Irlanda. Para entonces en Holanda ya se había asistido al desarrollo de un arte propio de jardín, íntimamente ligado al agua, sorprendentemente no demasiado bien conocido y que será uno de los temas de esta investigación. Finalmente, se propone una lectura conjunta de toda esta serie de intervenciones que tienen como argumento el agua, en la que se integra la información procedente de distintos campos de estudio, cada una con su metodología particular. El resultado es una tesis en la que el jardín y el territorio son tratados desde un nuevo y enriquecedor punto de vista. ABSTRACT Geographical space, understood as the territory that provides support to human life and civilization, has always been strongly subjected to the presence of water. From Prehistory man gave to water, along with other elements that ensured or protected life, a higher value than the merely human. At the same time and in a natural way, the garden, in its beginnings with a close relationship with agriculture and landscape, soon developed as the appropriate ground for the creation of new artificial aquatic forms, in a process that seems to have a turning point in the Renaissance, when most of the basic waterworks and resources were already fully established. This development and its outcomes are the subjects of the first part of the thesis: its scope has been to analyse how water configures, qualifies and might even help to construct the garden or landscape attached to it; and to establish the possible links between these two fields of study. Although history based, the point of view here is mainly conceptual, studying the water components understood as composite elements. This exploratory research has been essential to deeply understand the water patterns shown in the Renaissance and Mannerist garden and landscape, periods in which the two case studies are inserted. Without falling in extreme determinism, it can be accepted however, that garden, as a cultural expression linked to environment, is strongly dependant on territorial setting; something particularly evident in those areas where specific geography has been a clear history conditioning factor. This is the reason that leads to choose the Netherlands and Spain to deepen this study, no so much for their interesting cultural and politics relations as for the suggestive and profound contrast of their physical environment and climate. The Iberian Peninsula, geographically the limit of the known world in Occident until the end of the Medium Age, and by this circumstance understood as endpoint, more a destination than a crossroad, a territory of permanence and fusion, but also subjected to water shortage; is thus associated with the universe and tradition of the meridional garden imported from Orient. In the opposite, the Netherlands, a transitional space between the sea and the “real” firm land, is a territory permeated by water and crossed by big rivers. Always with an ambivalent relationship with water, sometimes seen as a threat and sometimes as a source of new opportunities, it was in the other hand the adequate land for the development of a special model of Northern garden. A garden that will not arise, however, from the clearing of woods as in the Nordic archetype, but that will grow on plains originally saturated of water or directly waterlogged. The timeframe of the two cases has 1548 as the initial year, moment in which Philip II, yet prince, made his first trip to the Low Lands and imbibed the Dutch garden model. The later and bountiful garden works of the king, always with the water as the main focus, adapted the imported model to the Spanish ground and geography. The final date is fixed in 1648, just a century after, in coincidence with the Westfalia Peace; a treaty that implied the total political reorganization of the European territory and the end of the Spanish hegemony in the continent. In Holland, only two years later, William III of Orange, Stadtholder of the United Provinces and also future king of England, Scotland and Ireland, was born. But by then the Netherlands had developed an own garden art, closely linked to water. This type garden, surprisingly not very well known, and its relationship with water, will be other of the addressing questions of this work. Finally, the investigation merges the different interventions that have water as an argument, integrating all the fields considered with their particular methodological approaches. The final result is a thesis in which garden and territory are treated from a new and enriching perspective.
