Hermeneutical Outlines in and of Dante’s Legal Theory

Based upon the concept of Law qualified in Monarchia, II.50, Dante was not only a general philosopher (a lover of knowledge) as well as a political disputant in his times, but also his primary contribution (not always obvious) in legal speculation could be demonstrated. In fact, if his thought reflected the platonic ordo sapientiae through a deep intersection between téchne and episteme (phronesis) toward a linguistic koiné, could we say the same thing on his concept of justice as a rational ars boni et aequi? This essay aims to depict Dante as legal theorist of his times and theorist of Justice beyond them, adopting the hermeneutical point of view, not just as an interest into textual interpretation but referring his use of language as form of life and his works an inexhaustible sources of education for legal philosophy

An educational path for the magnetic vector potential and its physical implications

We present an educational path on the magnetic vector potential A addressed to undergraduate students and to pre-service physics teachers. Starting from the generalized Ampere-Laplace law, in the framework of a slowly varying time-dependent field approximation, the magnetic vector potential is written in terms of its empirical referent, i. e. the conduction current. Therefore, once the currents are known, our approach allows a clear and univocal physical determination of A overcoming the mathematical indeterminacy due to the gauge transformations. We have no need to fix a gauge, since for slowly varying time-dependent electric and magnetic fields, the natural gauge for A is the Coulomb one. We stress the difference between our approach and those usually presented in the literature. Finally, a physical interpretation of the magnetic vector potential is discussed and some examples of calculation of A are analysed

Imogen and Desdemona: A Comparative Study of Shakespearean Heroines

openThe aim of this study is to examine two female characters of Shakespeare’s theatre, Desdemona, from the tragedy “Othello”, and Imogen, from the romance “Cymbeline”, juxtaposing their shared traits and distinguishing features. Since the plays have some similarities in their plotlines, it will focus on some central scenes, such as the husbands’ accusation of infidelity, a critical juncture in both plays. This research analyzes the agency and passivity of these two women’s characters, revealing their identities through their actions and dialogues. Desdemona and Imogen have distinct strengths and vulnerabilities: Desdemona is innocent and shows unwavering devotion to Othello, while Imogen displays resilience and adaptability in the face of adversity. Their responses to accusations of betrayal provide a compelling lens through which it is possible to analyze societal expectations and gender dynamics of Shakespearean England.The aim of this study is to examine two female characters of Shakespeare’s theatre, Desdemona, from the tragedy “Othello”, and Imogen, from the romance “Cymbeline”, juxtaposing their shared traits and distinguishing features.

Bio-hythane production from food waste by dark fermentation coupled with anaerobic digestion process: A long-term pilot scale experience

In this paper are presented the results of the investigation on optimal process operational conditions of thermophilic dark fermentation and anaerobic digestion of food waste, testing a long term run, applying an organic loading rate of 16.3 kgTVS/m3d in the first phase and 4.8 kgTVS/m3d in the second phase. The hydraulic retention times were maintained at 3.3 days and 12.6 days, respectively, for the first and second phase. Recirculation of anaerobic digested sludge, after a mild solid separation, was applied to the dark fermentation reactor in order to control the pH in the optimal hydrogen production range of 5-6. It was confirmed the possibility to obtain a stable hydrogen production, without using external chemicals for pH control, in a long term test, with a specific hydrogen production of 66.7 l per kg of total volatile solid (TVS) fed and a specific biogas production in the second phase of 0.72 m3 per kgTVS fed; the produced biogas presented a typical composition with a stable presence of hydrogen and methane in the biogas mixture around 6 and 58%, respectively, carbon dioxide being the rest

La pseudo-fallacia dell’argumentum (sub sub-genus) “ad hominem” quale enzima retoricamente onto-teleo-t(etico) per / dell’oratore

The paper provides to give a minimal contribution about a typical argumentation scheme which called "ad hominem". Especially, this mode of conduct a dialogue and arguing towards an opponent has been revisited by not long past approaches on Argumentation Theory with the aim to re-legitimate it in logical context and re-consider its consequences in terms of validity, consistence and alethic thinking. Ad hominem argument is part of rational discussion and informs audience about the coherence between speaker and his favored thesis

Smart approaches to food waste final disposal

Food waste, among the organic wastes, is one of the most promising substrates to be used as a renewable resource. Wide availability of food waste and the high greenhouse gas impacts derived from its inappropriate disposal, boost research through food waste valorization. Several innovative technologies are applied nowadays, mainly focused on bioenergy and bioresource recovery, within a circular economy approach. Nevertheless, food waste treatment should be evaluated in terms of sustainability and considering the availability of an optimized separate collection and a suitable treatment facility. Anaerobic codigestion of waste-activated sludge with food waste is a way to fully utilize available anaerobic digestion plants, increasing biogas production, energy, and nutrient recovery and reducing greenhouse gas (GHG) emissions. Codigestion implementation in Europe is explored and discussed in this paper, taking into account different food waste collection approaches in relation to anaerobic digestion treatment and confirming the sustainability of the anaerobic process based on case studies. Household food waste disposal implementation is also analyzed, and the results show that such a waste management system is able to reduce GHG emissions due to transport reduction and increase wastewater treatment performance

First- and second-generation valorisation of wastes and residues occurring in the food supply chain

Despite the high potential to increase sustainability of food systems, wastes and by-products occurring in the food supply chain are currently only partially valorised at different value-added levels. First-generation valorisation strategies that aim at utilisation of complete material streams for production of animal feed, energy, compost and/or specific consumer applications are already widely implemented and experience further dissemination and/or development (e.g. biohydrogen/biohythane production) – either in the form of single processes or as part of cascade utilisations. Second-generation valorisation strategies comprise various forms of fractionised utilisation of material streams. They rely on integration of adapted recovery and conversion procedures for specific components in order to obtain sequentially different classes of products, e.g. fine chemicals, commodity products and biofuels. Such advanced strategies are particularly suitable for wastes and by-products occurring during industrial food processing. Valorisation of food by-products for functional food is an emerging trend

Magnetoencephalography in Stroke Recovery and Rehabilitation

Magnetoencephalography (MEG) is a non-invasive neurophysiological technique used to study the cerebral cortex. Currently, MEG is mainly used clinically to localize epileptic foci and eloquent brain areas in order to avoid damage during neurosurgery. MEG might, however, also be of help in monitoring stroke recovery and rehabilitation. This review focuses on experimental use of MEG in neurorehabilitation. MEG has been employed to detect early modifications in neuroplasticity and connectivity, but there is insufficient evidence as to whether these methods are sensitive enough to be used as a clinical diagnostic test. MEG has also been exploited to derive the relationship between brain activity and movement kinematics for a motor-based brain-computer interface. In the current body of experimental research, MEG appears to be a powerful tool in neurorehabilitation, but it is necessary to produce new data to confirm its clinical utility
