Camp de futbol a Corbera de Llobregat

El projecte consisteix en la recuperació de l'espai d’una antiga pedrera de guix que els últims anys s'ha destinat a abocador municipal. En aquest espai s'hi ubicarà el nou camp de futbol del Corbera de Llobregat. Aquest exercici es projecta amb la intenció d’integrar l’entorn paisatgístic actual per a que englobi activitats esportives i formi una unitat territorial en un terreny que va ser molt explotat en el passat. La implantació dels nous usos son: un camp de futbol (amb un edifici de vestidors i grades amb marquesina per a 250 espectadors), una zona esportiva, i aparcaments públics per a l’equipament

Nutritional screening as part of nursing care

Trabajo fin de grado en EnfermeríaContexto: La desnutrición relacionada con la enfermedad es un problema tan frecuente como ignorado. Las causas que la provocan son múltiples y variadas, aunque cobra especial relevancia el papel de las enfermeros/as que trabajan en Atención Especializada. Esta situación ha llevado a la elaboración de Planes Estratégicos que aboguen por el cribado obligatorio tanto al ingreso como al alta del paciente. Objetivo: Determinar los motivos por los que dichos profesionales muestran poca sensibilización con el estado nutricional de los pacientes. Resultados: Son varias las barreas percibidas por las enfermeros/as que dificultan la realización del cribado y evaluación nutricional. La falta de conocimientos y de entrenamiento en la utilización de las herramientas de cribado influye de forma significativa en su realización. Además, prefieren el empleo de otros métodos y del juicio personal para realizar esta actividad, que junto con la importancia que le otorgan, determina la priorización del cribado y evaluación nutricional o de otras actividades. Uno de los factores que influye es la falta de tiempo. Conclusión: Ante la escasez de bibliografía, se hace necesario realizar estudios de investigación que permitan visibilizar los factores que dificultan la puesta en marcha de las herramientas de cribado y la evaluación nutricional de los pacientes hospitalizados.Context: Disease related-malnutrition is a problem as frequent as ignored. Causes are multiple and varied, although the nurses’ role working in Specialized Care is particularly relevant. This situation has led to the development of Strategic Plans that advocate for mandatory nutrition screening both at admission and discharge of the patient. Objective: Determine the reasons why these professionals show little awareness to the nutritional status of patients. Results: There are several barriers perceived by nurses that make it difficult to carry out nutritional screening and nutrition assessment. The lack of knowledge and training in the use of screening tools influences significantly their implementation. In addition, they prefer the use of other methods and the personal judgment to carry out this activity. Along with the importance they attach to it, determines the prioritization of screening and nutritional assessment or other activities. One of the factors that influences in it is the lack of time. Conclusion: Due to the scarcity of bibliography, it is necessary to carry out research studies that make it possible to visualize the factors that hinder the implementation of screening tools and the nutrition assessment of hospitalized patients

A study of the flow-field evolution and mixing in a planar turbulent jet using direct numerical simulation

Turbulent plane jets are prototypical free shear flows of practical interest in propulsion, combustion and environmental flows. While considerable experimental research has been performed on planar jets, very few computational studies exist. To the authors’ knowledge, this is the first computational study of spatially evolving three-dimensional planar turbulent jets utilizing direct numerical simulation. Jet growth rates as well as the mean velocity, mean scalar and Reynolds stress profiles compare well with experimental data. Coherency spectra, vorticity visualization and autospectra are obtained to identify inferred structures. The development of the initial shear layer instability, as well as the evolution into the jet column mode downstream is captured well. The large- and small-scale anisotropies in the jet are discussed in detail. It is shown that, while the large scales in the flow field adjust slowly to variations in the local mean velocity gradients, the small scales adjust rapidly. Near the centreline of the jet, the small scales of turbulence are more isotropic. The mixing process is studied through analysis of the probability density functions of a passive scalar. Immediately after the rollup of vortical structures in the shear layers, the mixing process is dominated by large-scale engulfing of fluid. However, small-scale mixing dominates further downstream in the turbulent core of the self-similar region of the jet and a change from non-marching to marching PDFs is observed. Near the jet edges, the effects of large-scale engulfing of coflow fluid continue to influence the PDFs and non-marching type behaviour is observed.Peer ReviewedPostprint (published version

Large-eddy simulation of Rayleigh-Taylor turbulence with compressible miscible fluids

Turbulence developed from Rayleigh-Taylor instability between two compressible miscible fluids in an unbounded domain is addressed in this paper. It is demonstrated that the turbulent Mach number in the turbulent core has an upper bound, independent of the density ratio under a broad range of initial mean configurations. The initial thermodynamic state of the system determines the amount of potential energy per unit mass involved in the turbulent mixing stage, and thus the characteristic level of turbulent fluctuations that is achievable is linked to the characteristic speed of sound such that the turbulent Mach number is limited. For the particular case of an ideal gas, this bound on the turbulent Mach number is found to be between 0.25 and 0.6, depending on the particular initial thermodynamic state. Hence, intrinsic compressibility effects those owing to large Mach number are likely to be limited in the turbulent stage of a pure Rayleigh-Taylor problem. This result is confirmed by large-eddy simulations LES of systems with density jumps at the interface of 3: 1, a density ratio for which there is extensive data available in the literature. The LES predictions of the mixing depth growth and overall mixing agree with results previously obtained in incompressible configurations with a negligibly small Mach number, and the data fully describing the Reynolds stresses and the budget of the resolved turbulent kinetic energy equation are provided.Peer ReviewedPostprint (published version

The Solar Disk at High Energies

High energy cosmic rays illuminate the Sun and produce an image that could be observed in up to five different channels: a cosmic-ray shadow (whose energy dependence has been studied by HAWC); a gamma-ray flux (observed at E 200 GeV by Fermi-LAT); a muon shadow (detected by ANTARES and IceCube); a neutron flux (undetected, as there are no hadronic calorimeters in space); a flux of high energy neutrinos. Since these signals are correlated, the ones already observed can be used to reduce the uncertainty in the still undetected ones. Here we define a simple setup that uses the Fermi-LAT and HAWC observations to imply very definite fluxes of neutrons and neutrinos from the solar disk. In particular, we provide a fit of the neutrino flux at 10 GeV–10 TeV that includes its dependence on the zenith angle and on the period of the solar cycle. This flux represents a neutrino floor in indirect dark matter searches. We show that in some benchmark models the current bounds on the dark matter–nucleon cross section push the solar signal below this neutrino floor.Spanish GovernmentJunta de Andalucia PID2019-107844GB-C21/AEI/10.13039/501100011033 FQM 101 P18-FR-505

On the role of large-scale updrafts and downdrafts in deviations from Monin-Obukhov similarity theory in free convection

We investigate by means of direct numerical simulation how large-scale circulations produce deviations from Monin–Obukhov similarity theory (MOST) in the limit of free convection, disentangling the role of large-scale downdrafts from updrafts using conditional analysis. We compare the convective boundary layer to two other free-convective flows: Rayleigh–Bénard convection with an adiabatic top lid and classical Rayleigh–Bénard convection. This serves a dual purpose: firstly, to ascertain how changes in the upper boundary conditions and thereby in the large-scale circulations modify the near-surface behaviour and secondly, to assess to what extent we can extrapolate results from idealized systems to the unstable atmospheric surface layer. Using a low-pass filter to define the large scales we find that, whilst deviations from MOST occur within large-scale downdraft regions, strong deviations also occur within large-scale updraft regions. The deviations within updrafts are independent of the filter length scale used to define the large-scale circulations, independent of whether updrafts are defined as ascending air, or as air that is both ascending and positively buoyant, and are not due to changes with height of the updraft area fraction. This suggests that even updraft properties are not just determined locally, but also by outer scales. Cold, strong downdrafts in classical Rayleigh–Bénard convection notably modify the near-surface behaviour compared to the other two systems. For the moderate Reynolds numbers considered, Rayleigh–Bénard convection with an adiabatic top lid thus seems more appropriate than classical Rayleigh–Bénard convection for studying the unstable atmospheric surface layer in the limit of free convection.Peer ReviewedPostprint (published version

Generación de interfaces gráficas por medio de anotaciones en Java

La sociedad actual está completamente informatizada de tal manera que nunca lo habríamos imaginado. Cualquier pequeño negocio, cualquier empresa o cualquier multinacional necesita estar informatizada para desempeñar su función. En este proceso de informatización entran en juego los programas desarrollados de cara a usuarios “básicos”, entendiendo como básicos a los usuarios sin formación en informática. Todos estos programas necesitan una apariencia visual atractiva e intuitiva para que los usuarios la utilicen, dicho en un lenguaje más técnico, todos los programas necesitan tener una interfaz gráfica de usuario. La creación de estas ventanas es un trabajo que a los programadores no les gusta nada, ya que les parece un trabajo muy costoso y que necesita mucho tiempo. Se prefiere dejar esta creación a diseñadores gráficos, pero como normalmente no se puede disponer de uno se ha intentado solucionar este problema de la mejor manera posible. Esta solución es crear un generador de código, que genere las interfaces gráficas. Por estas razones se ha decido crear el APT Processor. APT Processor es una herramienta que permite la creación automática de interfaces gráficas de usuario por medio de Anotaciones en el lenguaje de programación Java. Con unas pequeñas configuraciones el desarrollador de software tendrá creadas dinámicamente las interfaces gráficas que desee. Estas interfaces gráficas que se generan son bastante sencillas, pero incluyen validaciones de datos y alguna pequeña personalización. Gracias a la utilización de esta herramienta se podrá ahorrar tiempo en el desarrollo de software de usuario, ya que no será necesario programar las interfaces gráficas, tan solo la funcionalidad del programa.Today's society is completely computerized as we would have never imagined. Every small company, bussiness or multinational needs to be computerized to perform its function. In this computerized process developed programs to "basic" users come on the scene, meaning as "basic" users thoose users without computer knowledge. All these programs need an intuitive and atractive visual appereance for users to use it, in a more technical lenguaje, all programs need to have a graphical user interface. This windows creation is a work that developers do not like, because we think it is a very expensive work and it takes too much time to performe. We prefere to leave it to Graphic Designers, but as you cannot usually have one, it has been attempting to solve this problem in the best possible way. This solution is to create code generator wich generate graphical interfaces. For these reasons APT Processor has been created. APT Processor is a tool that enables automatic creation of graphical user interfaces by Java Annotations. With small configurations, software developer will have dynamically generated graphical interfaces you want. This generated graphical interfaces are very simple, but include data validation and some small customization. By using this tool, you can save development time, and it will not be necessary to program graphical interfaces, only the functionality of the program

Las empresas Born-Global en España

Trabajo de fin de Grado. Grado en Administración y Dirección de Empresas. Curso académico 20--[ES] En las últimas décadas, se ha incrementado el interés de algunos economistas por el fenómeno de las empresas nacidas globales o “Born Globals”, dando lugar a la aparición de numerosos estudios al respecto. Sin embargo, aún con toda esta información disponible, muchas personas son incapaces de explicar, con exactitud, qué es una empresa nacida global. En este trabajo, daremos una definición de estas entidades, aportando características comunes y explicando sus atípicos modelos de internacionalización. Analizaremos, de manera general, estos negocios dentro del territorio español, complementando todo ello con un estudio en profundidad de cuatro casos reales de Born Globals, que nos permitirán saber si la literatura existente respecto a estas empresas es completa o no
