La Seconda Vita dell'Ambiente Costruito
2021
Il contributo inquadra i saggi, gli studi, le ricerche e progetti pubblicati sul numero 9 di AGATHÓN su ‘La Seconda Vita dell’Ambiente Costruito’, tema di interesse per il mondo accademico, delle professioni e dell’industria. Cambiamenti climatici, eccessivo consumo di suolo e di risorse non rinnovabili, produzione sempre crescente di rifiuti, emergenza pandemica e crisi socio-economica globale sono entrati di fatto nel nostro quotidiano: seppur drammatiche, per certi versi, tali questioni possono essere colte come un’opportunità per ripensare il modo e il mondo in cui viviamo. In questo contesto di ‘rivoluzione’(Floridi, 2020) e di ‘policrisi’ (Losasso, 2020), e con riferimento specifico a…
Non solo Platone. Il primato dell'oralità nel retore Alcidamante
2020
Il saggio è dedicato all’orazione Sugli autori dei discorsi scritti o sui sofisti, attribuita al retore Alcidamante, discepolo di Gorgia e attivo in Atene tra il 410 e il 365 a.C. Argomento dell’orazione è il serrato confronto tra due differenti modalità oratorie, l’autoschediazein (“parlare a braccio”) — cui Alcidamente accorda una netta superiorità — e il "gegrammena legein (“pronunciare discorsi scritti”). L’interesse di questo testo (databile con buona approssimazione intorno al 390 a. C) consiste essenzialmente nel rappresentare un punto di vista specificamente retorico sulla questione delle differenze tra scritto e parlato. Nonostante alcune significative convergenze con il ben più ce…

2013
Il volume Tommaso Maria Napoli Utriusque Architecturae Compendium Roma 1688 Breve trattato sulle fabbriche civili e militari e la conservazione delle architetture del frate domenicano Tommaso Maria Napoli, vuole contribuire ad accrescere le nostre conoscenze sui principi che dovevano sottendere alla realizzazione dell’architettura civile e militare del periodo barocco e tardo barocco, così come espressi nel breve trattato scritto dal frate architetto, nato a Palermo, Tommaso Maria Napoli (1659-1725), e pubblicato a Roma alla fine del Seicento. Alla traduzione dal latino del trattato, redatta da esperti (Fabio Zarbo e Pietro Zarbo), è inclusa un’interessante ricerca, redatta congiuntamente c…
Resting state FMRI: A tool to investigate functional connectivity modulation induced by transcranial direct current stimulation of the motor network
2016
Introduction: Resting-state functional connectivity (fcMRI) represents a novel fMRI approach that allows detection of temporal correlations in spontaneous BOLD signal oscillations while subjects rest quietly in the scanner. Under resting conditions the brain is engaged in spontaneous activity that causes a low frequencies (<0.1 Hz) BOLD signal fluctuations. Functional connectivity (FC) can be defined as the synchrony of neural activity among spatially distant regions. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that is known to modulate cortical activity and FC among brain regions, as measured by functional magnetic resonance imaging. This st…
Los canecillos de la Capilla del Cementerio de San Juan del Hospital de Valencia
2020
In the medieval cemetery of the Historic Site of San Juan del Hospital of Valencia is housed a small funeral chapel founded in the late thirteenth century by the knight Arnau de Romaní. Along its cornice there are a series of heads of animals and humans that are one of the few sculptural vestiges inserted into the Romanesque iconographic tradition that are preserved in the city. So far they have not aroused the interest of specialists and no one has dedicated a detailed study to these curious and interesting images located in the marginal spaces of such a beautiful building. This article aims to complete this gap addressing the study of the corbels of the small temple, projecting a thematic…
EEG Resting-State Functional Networks in Amnestic Mild Cognitive Impairment.
2022
Background. Alzheimer’s cognitive-behavioral syndrome is the result of impaired connectivity between nerve cells, due to misfolded proteins, which accumulate and disrupt specific brain networks. Electroencephalography, because of its excellent temporal resolution, is an optimal approach for assessing the communication between functionally related brain regions. O bjective. To detect and compare EEG resting-state networks (RSNs) in patients with amnesic mild cognitive impairment (aMCI), and healthy elderly (HE). Methods. We recruited 125 aMCI patients and 70 healthy elderly subjects. One hundred and twenty seconds of artifact-free EEG data were selected and compared between patients with aM…
Resting Energy Expenditure of Master Athletes: Accuracy of Predictive Equations and Primary Determinants
2021
Resting energy expenditure (REE) is determined mainly by fat-free mass (FFM). FFM depends also on daily physical activity. REE normally decreases with increased age due to decreases in FFM and physical activity. Measuring REE is essential for estimating total energy expenditure. As such, there are a number of different equations in use to predict REE. In recent years, an increasing number of older adults continue to participate in competitive sports creating the surge of master athletes. It is currently unclear if these equations developed primarily for the general population are also valid for highly active, older master athletes. Therefore, we tested the validity of six commonly-used equa…
Palladium-catalyzed heteroaryl thioethers synthesis overcoming palladium dithiolate resting states inertness: Practical road to sulfones and NH-sulfo…
2018
International audience; We provide efficient synthetic access to heteroaryl sulfones in two-steps using a simple palladium-1,1'-bis [(diphenyl)phosphanyl]ferrocene catalyst to form in high yields variously functionalized heteroaromatic thioethers. Pyridinyl-containing substrates can be subsequently selectively oxidized into sulfones and NH-sulfoximines by using very mild oxidation conditions with a high functional group tolerance. In the palladium catalyzed C-S coupling of heteroaromatic thiols, reactivity limitation is attached with electron-deficient thiols. We show that this limitation can be resolved by the successful use of 2-bromoheteroarenes in the C-S coupling. We established herein…
Internet and computer game addiction - a review of current neuroscientific research
2011
IntroductionA significant part computer game players and internet users show clinical features of abuse and addiction (loss of control, withdrawal symptoms, tolerance, continuation of game play even with increasing negative consequence in social and academic life). Similar mechanisms are suggested to underlie the pathogenesis and maintenance of internet and computer game addiction and substance-related addictions.ObjectivesNeuroscientific research on internet and computer game addiction is sparse, yet emerging. To review previous studies is the objective of the present project.AimsWe aim to identify common findings regarding the neurophysiological processes underlying internet and computer …
Questions and controversies in the study of time-varying functional connectivity in resting fMRI.
2020
The brain is a complex, multiscale dynamical system composed of many interacting regions. Knowledge of the spatiotemporal organization of these interactions is critical for establishing a solid understanding of the brain’s functional architecture and the relationship between neural dynamics and cognition in health and disease. The possibility of studying these dynamics through careful analysis of neuroimaging data has catalyzed substantial interest in methods that estimate time-resolved fluctuations in functional connectivity (often referred to as “dynamic” or time-varying functional connectivity; TVFC). At the same time, debates have emerged regarding the application of TVFC analyses to re…
