Conflicting conceptualisations of ‘democracy’ in the German Bundestag during the anti-nuclear demonstrations, 1995-2001
2018
A vigorous anti-nuclear movement emerged in Germany in the mid 1990s, when spent nuclear fuel elements began to be transported to the interim storage facility in Gorleben, Lower Saxony. Resistance to nuclear transportation continued to grow in strength throughout the 1990s. The protests expressed people’s distrust and lack of confidence in political institutions and decision-making processes. In the German Bundestag, these events relating to Gorleben caused significant political struggles over the principles and meanings of German democracy. Parliamentarians voiced competing counterarguments about the legitimacy of these demonstrations, on the one hand, and the legitimacy of the nuclear ene…
Tuning Azoheteroarene Photoswitch Performance through Heteroaryl Design
2017
International audience; Photoswitchable compounds, which can be reversibly switched between two isomers by light, continue to attract significant attention for a wide array of applications. Azoheteroarenes represent a relatively new but understudied type of photoswitch, where one of the aryl rings from the conventional azobenzene class has been replaced with a five-membered heteroaromatic ring. Initial studies have suggested the azoheteroarenes – the arylazopyrazoles in particular – to have excellent photoswitching properties (quantitative switching and long Z isomer half-life). Here we present a systematic computational and experimental study to elucidate the origin of the long thermal hal…
Pollutant Emissions in Ports: A Comprehensive Review
2021
In recent decades, maritime transport demand has increased along with world population and global trades. This is associated with higher pollution levels, including the emissions of GHG and other polluting gases. Ports are important elements within maritime transport and contribute themselves to pollutant emissions. This paper aims to offer a comprehensive yet technical review of the latest related technologies, explaining and covering aspects that link ports with emissions, i.e., analyzing, monitoring, assessing, and mitigating emissions in ports. This has been achieved through a robust scientific analysis of very recent and significant research studies, to offer an up-to-date and reliable…
Charged particle multiplicity distributions in restricted rapidity intervals in Z0 hadronic decays.
1991
The multiplicity distributions of charged particles in restricted rapidity intervals in Z0 hadronic decays measured by the DELPHI detector are presented. The data reveal a shoulder structure, best visible for intervals of intermediate size, i.e. for rapidity limits around ±1.5. The whole set of distributions including the shoulder structure is reproduced by the Lund Parton Shower model. The structure is found to be due to important contributions from 3-and 4-jet events with a hard gluon jet. A different model, based on the concept of independently produced groups of particles, "clans", fluctuating both in number per event and particle content per clan, has also been used to analyse the pres…
Downscaling climate change impacts, socio-economic implications and alternative adaptation pathways for islands and outermost regions
2021
Questo libro fornisce una panoramica completa degli scenari futuri del cambiamento climatico e delle problematiche di gestione associate all'impatto del cambiamento climatico sull'economia blu delle isole e delle regioni ultraperiferiche europee. La pubblicazione raccoglie i principali risultati dei risultati della ricerca del progetto Soclimpact, con l'obiettivo di aumentare la consapevolezza sociale tra i responsabili politici e l'industria sulle conseguenze dei cambiamenti climatici a livello locale e fornire informazioni basate sulla conoscenza nella progettazione delle politiche di sostegno, dal livello locale a quello nazionale. This book provides a comprehensive overview of the futur…
A comparative study on campus sustainability in higher education sector in Hong Kong and Finland
2015
This thesis presents a comparative study examining the practices of campus sustainability in Higher Education Sectors between Hong Kong and Finland. Campus sustainability is a trend during the last decade as a result of numerous declarations and meetings for sustainable development in Higher education all over the world. In this thesis, the investigated areas are focused on environmental sustainability and Social sustainability. This study used the content analysis method to analyze public available documents from the selected fifteen Higher education institutions in Hong Kong and Finland. The first stage was a description of the current overall situations of campus sustainability in the tw…
¿Es la energía nuclear la solución al cambio climático? Editorial
2004
El 24 de mayo 2004 el periódico inglés The Independent publicó un artículo de James Lovelock, el conocido autor de la Hipótesis Gaia , con el título Nuclear power is the only green solution ( La energía nuclear es la única solución verde ) que tuvo una notable repercusión en los medios de comunicación, en los que se llegó a afirmar que el propio Mikhail Gorbatxov, Presidente de Green Cross International, apoyaba estas tesis favorables al uso de la energía nuclear.
Il principio di gerarchia delle resistenze capacity design
2012
The devastating effects generated by earthquakes occurred in different parts of the world have attract at a major interest in Earthquake Engineering. This branch of Structural Engineering studies the response and capacity of structural systems subjected to seismic actions, and develops design and prediction methods aimed at achieving adequate safety standards in presence of seismic events. A strategy used for the seismic prediction of RC structures, based on the capacity design of structural elements is the "hierarchy of strengths" (HS) principle. The paper shows how a proper use of the HS capacity design method can be included within the seismic design of RC structures achieving high level…
Assessment for the mean value total dressing method: Comparison with coupled cluster including triples methods for BF, NO+, CN+, C2, BeO, NH3, CH2, H…
1997
Limited previous experience with the mean value total dressing (MVTD) method had shown that MVTD energies for closed shell systems are generally better than CCSD(T) ones compared to FCI. The method, previously published as total dressing 2′(td-2′), is based on the single reference intermediate Hamiltonian theory. It is not a CC method but deals in a great part with the same physical effects that CC methods that incorporate amplitudes of triples such as CCSDT or its CCSDT-1n approaches. A number of test calculations comparing to diverse CC methods, as well as FCI and experiment when available, have been performed. The tests concern equilibrium energies in NH3 and CH2, equilibrium energies an…
State of the Art on Sustainability Assessment of Positive Energy Districts: Methodologies, Indicators and Future Perspectives
2021
The concept of Positive Energy District is one of the main areas of research and extensive applications of the principles of the clean energy transition within the building sector. In the past years, the most widely accepted definitions have focused specifically on carbon neutrality, while several other aspects regarding all sustainability approaches (including environmental, social and economic perspective) were included qualitatively or to a lesser degree. This paper proposes a discussion on the state of the art of the sustainability assessment of Positive Energy Districts, by investigating environmental, social and economic sustainability applications. The three sustainability dimensions…
