Color degradation mapping of rock art paintings using microfading spectrometry
2021
[EN] Rock art documentation is a complex task that should be carried out in a complete, rigorous and exhaustive way, in order to take particular actions that allow stakeholders to preserve the archaeological sites under constant deterioration. The pigments used in prehistoric paintings present high light sensitivity and rigorous scientific color degradation mapping is not usually undertaken in overall archaeological sites. Microfading spectrometry is a suitable technique for determining the light-stability of pigments found in rock art paintings in a non-destructive way. Spectral data can be transformed into colorimetric information following the recommendations published by the Commission …
A New Methodology to Assess Territorial Competence for Sustainable Local Development: The READI® (Resources-Actors-Dynamics) Matrix
2021
[EN] The ability of a territory to manage certain sustainable development processes increasingly depends on its capacity to apply previous diagnostic processes to its current situation. For this reason, methodologies that facilitate the detection of needs and/or potentialities of the territory are key to meeting its anticipated sustainable development goals. We present the most notable results of the research methodology carried out in the province of Valencia (Spain) that has enabled the construction of a matrix of indicators that allow these previous diagnostic processes to be put into practice at a local level, based on the participation of the territory's socioeconomic actors.
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. Ad…
Dopo la firmitas. Prospettiva metabolista di architetture resilienti
2019
Identificata per millenni attraverso la sua capacità di durare identica nel tempo – secondo il paradigma della firmitas vitruviana - l’architettura contemporanea è invece chiamata oggi ad un adattamento dinamico alle mutazioni del suo contesto. L’emergenza climatica è l’epifenomeno più evidente fra quelli che hanno orientato la disciplina verso l’indeterminatezza programmatica, la flessibilità morfologica, gli approcci sistemici aperti. Lontana dall’essere un semplice adeguamento tecnico a nuove esigenze quantitative, l’architettura resiliente chiarisce progressivamente i suoi termini teorici e le sue derivazioni culturali. Un approccio genealogico che traccia la riformulazione di alcuni te…
Consumer Demand for Environmental, Social, and Ethical Information in Fishery and Aquaculture Product Labels
2022
[EN] Customers' attention to sustainability labels in fishery and aquaculture products (FAPs) has been increasing in the last decades, and the industry has adapted to this growing interest by adopting fish ecolabels. However, there is a growing interest to widen the sustainability concept to include the social and ethical information of the fishery and aquaculture industry and to go further from the voluntary approach on the labeling of these aspects in FAPs. For this reason, using data from 2021 Eurobarometer and using machine learning techniques, we disentangle the characteristics of the FAP buyers that consider the importance of environmental impact, ethical, and social information appea…
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.
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…
Tecnologia e misure verdi verso un’architettura resiliente / Technology and green measures to a resilient architecture
2017
La portata degli effetti che i cambiamenti climatici comportano nei diversi territori, impone di ripensare l’attuale approccio al disegno della città. Il nuovo orientamento è diretto verso la progettazione resiliente (dal latino resilire cioè «rimbalzare») sostenibile, agile e antifragile che possa resistere e fare fronte alle attuali criticità. L’articolo focalizza l’attenzione sul ruolo fondamentale della tecnologia nel settore delle costruzioni per la mitigazione del microclima. The scope of the effects that climate change implies in different territories requires a rethink of the current approach to the city’s design. The new orientation is directed towards resilient design (from Latin …
Influence of substrate and temperature on the biodegradation of polyester-based materials: Polylactide and poly(3-hydroxybutyrate-co-3-hydroxyhexanoa…
2020
[EN] The extended use of polymers from renewable resources such as aliphatic polyesters or polyhydroxyalkanoates boosted the necessity to understand their behaviour in an end-of-life scenario. Although they can be degraded in reasonable shorter times than traditional polymers, understanding the degradation mechanisms under dissimilar conditions will contribute to further developments in this field. This work aimed to study the effect of temperature and substrate in the degradation of polylactide (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) in a simulated laboratory scale to ascertain their contribution, separately or in combination. For this purpose, nine parallel degradat…
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…
