Energy and Environmental Assessment of a Hybrid Dish-Stirling Concentrating Solar Power Plant

2022

Although the 2019 global pandemic slowed the growing trend of CO2 concentrations in the atmosphere, it has since resumed its rise, prompting world leaders to accelerate the generation of electricity from renewable sources. The study presented in this paper is focused on the evaluation of the energy and environmental benefits corresponding to the hypothesis of hybridizing a dish-Stirling plant installed on the university campus of Palermo (Italy). These analyses were carried out by means of dynamic simulations based on an accurate energy model validated with the experimental data collected during the measurement campaign that occurred during the period of operation of the reference plant. As…

Conoscere il diritto

2023

Il modo di concepire la conoscenza del diritto varia nel corso del tempo ed è influenzato da molteplici fattori. Seguendo Norberto Bobbio è possibile distinguere due modelli ideal-tipici di giurista: il “custode” di un diritto pre-esistente e il “creatore” di un diritto perennemente in fieri e indeterminato. Tale alternativa è tuttavia soltanto apparente; anche quando la scienza giuridica postula l’esistenza di un diritto-oggetto in attesa di essere conosciuto, essa in effetti non fa altro che presupporre una immagine ideologicamente caratterizzata del diritto. Di conseguenza, lo studioso del diritto non è mai un osservatore neutrale. Così anche il diritto-oggetto “custodito” dalla scienza …

LES ÉQUIVOQUES DU « CONSTITUTIONNALISME OCTROYÉ » : UN DÉBAT TRANSATLANTIQUE (I)

2015

In Portugal and in its former colonies, the expression "constitucionalismo outorgado » is part of the constitutional vocabulary since the granting of the Charter of 1826. The French inspiration is obvious ; however, no equivalent expression exists in France. This curiosity leads to measure all the ambiguity of the concept of "granted constitutionalism", an improbable oxymoron according to the president of the Portuguese Republic, Teófilo Braga. Is it about a simple political and linguistic claim, a temporary compromise at the end of a frustrated Revolution? Or does it translate a deeper program, to reconcile both sides of the constitutionalism, ancient and modern ?

THE AMBIGUITIES OF « GRANTED CONSTITUTIONALISM » : A TRANSATLANTIC DEBATE (II)

2017

After France, and before Brazil, the second article concerns Portugal. The portuguese legal framework was appropriate to stem the birth of the constituent power. Reconstructed on the basis of an apocryphal transcription of its founding pact, the Cortes of Lamego of 1143, the portuguese public law benefited on top of a written document born in the XVth century, the Ordenações. This double peculiarity, making "iberian liberties" a model of the ancient constitutionalism, explains the reverential respect for these medieval borders and the hatred following Dom Pedro's granting in 1826. In these conditions, and in spite of the program followed by a "granting power" which refuses to define itself …

Suicide, Social Bodies, and Danger : Taboo, Biopower, and Parental Worry in the Films Bridgend (2015) and Bird Box (2018)

2020

In my article I study two Anglophone feature films, Jeppe Rønde's Bridgend (2015) and Susan Bier's Bird Box (2018), from the viewpoints offered by visual cultural studies and the theoretical domains of taboo and biopower. Both systems of control respond to risks and dangers to society, taboo through ideas of contagion and biopower through normative, especially medical discourses by authorized instances of knowledge production. They are reflected also in the audio-visual popular culture seeking to make sense of suicide through entertaining and artistic means. The two films I study present suicide as a contagion that has supernatural (Bird Box) and social origins (Bridgend), and as a force of…

Ideological, Institutional and Affective Practices of Interpersonal Violence

2020

The first chapter presents the book’s point of departure as well as its central concepts and structure. It outlines the current understandings of and theoretical approaches to the intersections of violence, gender and affect. The starting point is that gendered violence and violating practices are embedded in social structures of power and in inequalities, institutions, regimes and the symbolic order. They are manifested in human interaction as well as in cultural discourses and representations. The chapter also gives an overview of the abundant research and various perspectives involved in analysing the intersections of violence, gender and affect as well as the continuities and interconne…

The Acceptable Alternative Vehicle Fuel Price

2019

Historically, petroleum fuels have been the dominant fuel used for land transport. However, the growing need for sustainable national economics has urged us to incorporate more economical and ecological alternative vehicle fuels. The advantages and disadvantages of them complicate the decision-making process and compel us to develop adequate mathematical methods. Alternative fuel (compressed natural gas, liquefied petroleum gas, and ethanol fuel mixtures), the standard prices and their ratios were investigated. A mathematical model to determine a critical ratio between alternative and conventional fuel prices had already been developed. The results of this were investigated. The results sho…

Synthetic Inertia Impact on Inter-Area Oscillations of the Continental Europe Power System

2020

The overall kinetic energy reduction due to increasing share of converter-interfaced generation (CIG) has been investigated so far by several works for systems of different types and sizes. The so called synthetic inertia is one of the most common and reviewed solutions to the issue of system inertia reduction. The paper investigates the effects of synthetic inertia as frequency service provided by the CIG sources for the Continental Europe (CE) synchronous area using a detailed large scale dynamic model. The model - provided in the basic form by the System Protection & Dynamics (SP&D) group of the ENTSOE - is properly developed substituting a determined amount of synchronous machin…

Coping with injury in powerlifting : stress-injury model perspective

2017

A need to evaluate psychological antecedents to injury in strength-based sports is evident. Powerlifting especially has seen a rise in participation rates (International Paralympic Committee; Powerlifting Australia Ltd.; British Weight Lifting), also resulting in an increase in weightlifting-related injuries (Metzger et al., 2012). While much literature exists on mental stressors and coping mechanisms athletes encounter in the sport context, minimal research has attempted to understand how athletes involved in strength sports cope with stress and injury. The nature of strength sports overall differs from contact, speed-based, or even aesthetics-based sports. These essential differences are …
