A Tool to Assess Architectural Education from the Sustainable Development Perspective and the Students' Viewpoint
2021
[EN] Architectural education plays a fundamental role in achieving sustainable development by training future professionals who can contribute to sustainability through their practice. Nevertheless, to ensure the introduction of sustainable development in the education of future architects, it is fundamental to understand what is being done and what could be improved. Despite this, a big gap has been detected in the assessment of architectural education in Spain and worldwide. Thus, a close-ended questionnaire for students has been designed based on the outcomes from a literature review, exploratory interviews with specialists, and the qualitative analysis of two schools of architecture.

Medidas durante el COVID-19 y Derecho mercantil (Parte II: Derecho concursal).
2020
The crisis generated by the COVID-19 pandemic has forced it to take multiple measures of different kinds to mitigate its effects during the Alarm State. These measures include those that have effects on various commercial law institutions, such as those relating to insolvency issues.
A risk evaluation framework for the best maintenance strategy: the case of a marine salt manufacture firm
2020
Highlights • This paper proposes a MCDM framework to support risk evaluation for maintenance activities. • The ANP is proposed to select the best maintenance strategy on the basis of real systems’ features. • The ELECTRE III is used to prioritise the main risks related to the interventions of the selected maintenance policy. • The proposed framework is applied to a core subsystem of a real-world marine salt manufacture firm.
Aproximación a la Geografía del despilfarro en España: balance de las últimas dos décadas
2018
Este trabajo pretende ser una primera aproximación a la dimensión del despilfarro de recursos públicos en infraestructuras en España desde 1995 hasta la actualidad en los distintos niveles de gobierno. A partir de algunas precisiones sobre los conceptos de despilfarro y corrupción, se analiza, de una parte, la inversión y los sobrecostes en infraestructuras innecesarias impulsadas y ejecutadas por la Administración General del Estado en el ámbito de sus competencias, y de otra, infraestructuras, proyectos, eventos e inversiones fallidas, vacías o infrautilizadas acometidas por las Comunidades Autónomas y los gobiernos locales. Se abordan los déficit de marco institucional y de gobernanza te…

Effect of Chitin Whiskers on the Molecular Dynamics of Carrageenan-Based Nanocomposites
2019
[EN] Films of carrageenan (KC) and glycerol (g) with different contents of chitin nanowhiskers (CHW) were prepared by a solution casting process. The molecular dynamics of pure carrageenan (KC), carrageenan/glycerol (KCg) and KCg with different quantities of CHWs as a filler was studied using dielectric relaxation spectroscopy. The analysis of the CHW effect on the molecular mobility at the glass transition, T-g, indicates that non-attractive intermolecular interactions between KCg and CHW occur. The fragility index increased upon CHW incorporation, due to a reduction in the polymer chains mobility produced by the CHW confinement of the KCg network. The apparent activation energy associated…
MOF-Mediated Synthesis of Supported Fe-Doped Pd Nanoparticles under Mild Conditions for Magnetically Recoverable Catalysis**
2020
Metal–organic framework (MOF)-driven synthesis is considered as a promising alternative for the development of new catalytic materials with well-designed active sites. This synthetic approach is used here to gradually transform a new bimetallic MOF, with Pd and Fe as the metal components, by the in situ generation of aniline under mild conditions. This methodology results in a compositionally homogeneous nanocomposite formed by Fe-doped Pd nanoparticles that, in turn, are supported on iron oxide-doped carbon. The nanocomposite has been fully characterized by several techniques such as IR and Raman spectroscopy, TEM, XPS, and XAS. The performance of this nanocomposite as an heterogeneous cat…
Optimal Placement of Pressure Sensors Using Fuzzy DEMATEL-Based Sensor Influence
2020
[EN] Nowadays, optimal sensor placement (OSP) for leakage detection in water distribution networks is a lively field of research, and a challenge for water utilities in terms of network control, management, and maintenance. How many sensors to install and where to install them are crucial decisions to make for those utilities to reach a trade-off between efficiency and economy. In this paper, we address the where-to-install-them part of the OSP through the following elements: nodes' sensitivity to leakage, uncertainty of information, and redundancy through conditional entropy maximisation. We evaluate relationships among candidate sensors in a network to get a picture of the mutual influenc…
El Corredor Mediterráneo
2016
El Corredor Mediterráneo, como proyecto de eje ferroviario, constituye un elemento clave de la planificación española y europea. Además de tener un papel de infraestructura de transporte, también cristaliza en cuestiones económicas y políticas a distintos niveles territoriales. Representa un cambio en la lógica de ordenación del territorio, al reforzar el eje litoral en detrimento de los enlaces radiales con la capital. En este libro se propone entender cómo el Corredor viene a ser un patente factor que incita a revisar el papel de los distintos actores implicados -políticos, económicos, institucionales...-, así como a reinterpretar los paradigmas de la ordenación del territorio e interroga…
Brewer's spent grains as biofuels in combustion-based energy recovery processes: Evaluation of thermo-oxidative decomposition
2022
[EN] The high global generation of wastes and side streams from agri-food production has led to environmental impact and causes nature degradation due to their uncontrolled management. These wastes are profitable materials with significant economic value that could otherwise be exploited as new sources in the feed industry or the production of bioenergy. Among them, brewer¿s spent grain (BSG) is a solid by-product generated in the beerbrewing process that consists of the barley grain husks together with parts of the pericarp and seed coat layer. Although it is rich in fibres and proteins, its main use is currently limited to animal feed or simply deposition to landfills. This study pursues …
