The Decarbonisation of Galicia Using Renewable Marine Energy

Paper: 19th International Conference on Renewable Energies and Power Quality (ICREPQ’21) Almeria (Spain), 28th to 30th July 2021[Abstract] The objective of this paper is to examine the importance of independent arrays in the offshore renewable energy farms. In this context, several scenarios have been contemplated for a floating offshore renewable energy farm: a farm only using floating wave energy; a farm only using floating offshore wind energy; and a farm composed by floating wave energy and floating offshore wind energy installed in independent arrays. The article proposes a method to calculate the main economic parameters and decide their economic feasibility. A hypothetic offshore renewable energy farm located in the Galicia region (Spain) has been studied as case of study. Results show which of the scenarios has the best economic results. This method is worthwhile to compare different floating offshore renewable energy technologies in economic terms and help in the decision making of this new emerging sector that can help to rebuild Europe in the post-pandemic period.This research was funded by Project PID2019-105386RA-I00 “Design of a tool for the selection of offshore renewable energy locations and technologies: application to Spanish territorial waters (SEARENEW)”, financed by Ministerio de Ciencia e Innovación – Agencia Estatal de Investigación/10.13039/50110001103

A Software for Calculating the Economic Aspects of Floating Offshore Renewable Energies

[Abstract] The aim of this work is to develop a software to calculate the economic parameters so as to determine the feasibility of a floating offshore renewable farm in a selected location. The software can calculate the economic parameters of several types of offshore renewable energies, as follows: one renewable energy (floating offshore wind—WindFloat, tension leg platform (TLP), and spar; floating wave energy—Pelamis and AquaBuoy), hybrid offshore wind and wave systems (Wave Dragon and W2Power), and combined offshore wind and waves with different systems (independent arrays, peripherally distributed arrays, uniformly distributed arrays, and non-uniformly distributed arrays). The user can select several inputs, such as the location, configuration of the farm, type of floating offshore platform, type of power of the farm, life-cycle of the farm, electric tariff, capital cost, corporate tax, steel cost, percentage of financing, or interest and capacity of the shipyard. The case study is focused on the Galicia region (NW of Spain). The results indicate the economic feasibility of a farm of floating offshore renewable energy in a particular location in terms of its costs, levelized cost of energy (LCOE), internal rate of return (IRR), net present value (NPV), and discounted pay-back period. The tool allows for establishing conclusions about the dependence of the offshore wind resource parameters, the main distances (farm–shore, farm–shipyard, and farm–port), the parameters of the waves, and the bathymetry of the area selecte

Conservation laws, classical symmetries and exact solutions of the generalized KdV-Burgers-Kuramoto equation

For a generalized KdV-Burgers-Kuramoto equation we have studied conservation laws by using the multiplier method, and investigated its first-level and second level potential systems. Furthermore, the Lie point symmetries of the equation and the Lie point symmetries associated with the conserved vectors are determined. We obtain travellingwave reductions depending on the form of an arbitrary function. We present some explicit solutions: soliton solutions, kinks and antikinks

An X-ray Study of Local Infrared Bright Galaxies

We are carrying out detailed study of the X-ray and infrared (IR) properties of a sample of local (d < 70 Mpc) luminous infrared galaxies (LIRGs) using XMM-Newton and Spitzer (imaging and spectroscopy). The main goal is to study the extreme processes of star formation and/or active galactic nuclei (AGN) taking place in this cosmologically important class of galaxies. In this proceedings we present the preliminary results obtained from the analysis of the XMM-Newton X-ray images and the X-ray spectral modeling.Comment: 5 pages, to appear in Highlights of Spanish Astrophysics VI, Proceedings of the IX Scientific Meeting of the Spanish Astronomical Society held on September 13-17, 2010, in Madrid, Spai

Novelas Españolas ambientadas en Italia. Fra Filippo Lippi de Emilio Castelar / Bomarzo de Manuel Mujica Lainez

[ES] Las fuentes en las que se fundamenta la novela histórica proporcionan, además de una ambientación correcta de la acción, la veracidad necesaria para que el lector reconozca y admire el trabajo llevado a cabo por el autor. Este estudio se centra en descubrir las fuentes históricas, literarias, artísticas religiosas y culturales en las que se sustentan dos novelas histórica diferentes, pero con un marco común, el Renacimiento Italiano. Mientras que en "Fra Filippo Lippi" de Emilio Castelar, novela del último tercio del siglo XIX, la exactitud histórica está presentada en determinados capítulos que parecen ralentizar la acción, en "Bomarzo" de Manuel Mujica Lainez, de mediados del siglo XX, lo histórico está tan integrado que es difícil detectar qué parte se corresponde con la historia y cuál con la ficción. Las referencias literarias pertenecientes a un periodo que va desde los siglos XV y XVI hasta el presente de los autores, aportan a las novelas la necesaria relativización que hace a sus protagonistas portadores de una nueva inmortalidad. La exactitud de las descripciones, la configuración de los caracteres tanto renacentistas como contemporáneos, las perspectivas artísticas, religiosas, configuran estas dos obras en una serie de coincidencias difíciles de obviar. El ambiente histórico del Renacimiento Italiano queda reflejado en las novelas con la exactitud que le proporcionan las fuentes consultadas por los autores, y este estudio presenta una confrontación de dichas fuentes con el texto literario a fin de acreditar cómo dicho marco ayuda a delimitar la psicología de los protagonistas, que aunque son personajes históricos se amoldan a la idea de ficción que el autor pretende transmitir

Development and Innovation in Cooked Ham Produced in Spain

The production of cooked ham has been gaining popularity in recent years in Spain. In general, the production process carried out by the companies remains traditional, and different production methods are therefore being sought to innovate and improve the quality of the product. This is either through pig crossbreeding, varying additives and ingredients, improving some stages of the production process, or providing nutritional and health claims that are useful to guiding the purchasing decision of consumers. Obviously, this series of changes must be subject to Spanish and European regulations in order to be marketed inside and outside the countryDepto. de Química InorgánicaFac. de Ciencias QuímicasTRUEUCLMpu

Lie Point Symmetries, Traveling Wave Solutions and Conservation Laws of a Non-linear Viscoelastic Wave Equation

This paper studies a non-linear viscoelastic wave equation, with non-linear damping and source terms, from the point of view of the Lie groups theory. Firstly, we apply Lie's symmetries method to the partial differential equation to classify the Lie point symmetries. Afterwards, we reduce the partial differential equation to some ordinary differential equations, by using the symmetries. Therefore, new analytical solutions are found from the ordinary differential equations. Finally, we derive low-order conservation laws, depending on the form of the damping and source terms, and discuss their physical meaning.The support of the Plan Propio de Investigacion de la Universidad de Cadiz is gratefully acknowledged.

Service-Learning for Sustainability Entrepreneurship in Rural Areas: What Is Its Global Impact on Business University Students?

5296Service-Learning (SL) is a teaching innovation method that combines learning and social service objectives to improve educational quality and graduate employability. To date, there are hardly any studies on its global impact on university students. This paper describes and evaluates an SL experience for Sustainability Entrepreneurship in the context of Spanish Higher Education. Based on knowledge acquired in classrooms, multi-disciplinary teams of students from di erent subjects related to Business Administration o ered support to potential entrepreneurs from rural municipalities in the complex task of writing a successful Business Plan for their projects for local sustainability. Within this academic framework, our study has two goals: (1) to assess the self-perception of university students about the improvement in their curricular development, professional skills and civic-social responsibility after participating in the SL experience; and (2) to estimate its possible e ect on academic performance. The results show that the students acknowledged they had improved their social and sustainability commitment and their curricular development, and had acquired skills that society increasingly demands from future business professionals. Furthermore, service-students achieved significantly higher academic performance than a control group of non-participating students. These findings highlight the e ectiveness of SL to provide a more holistic education for business university students.S

Symmetry Analysis and Conservation Laws of a Generalization of the Kelvin-Voigt Viscoelasticity Equation

In this paper, we study a generalization of the well-known Kelvin-Voigt viscoelasticity equation describing the mechanical behaviour of viscoelasticity. We perform a Lie symmetry analysis. Hence, we obtain the Lie point symmetries of the equation, allowing us to transform the partial differential equation into an ordinary differential equation by using the symmetry reductions. Furthermore, we determine the conservation laws of this equation by applying the multiplier method
