Il sistema di copertura del Teatro Politeama di Palermo
2012
In the project of the Politeama’s Theater in Palermo, the Architect Almeyda summarizes, in an expressive and model balance, the technological component and geometrical/spatial shape, providing optimal solutions to a structural and functional problems. Thanks to its typological approach, thanks to its technological aspects and, specifically, thanks to its size and its style, the work offers us some interesting reflections about the technical choices carried out for the construction. The Author, basing on some original Almeyda’s drawings, deepens the geometric and compositional system of the roof. The daring and complex construction carried out in iron and glass, modern and progressive in for…
How football team composition constrains emergent individual and collective tactical behaviours: Effects of player roles in creating different landsc…
2021
The aim of the present study was to examine how team composition of players with different roles constrains individual and collective tactical behaviours, and ball possession effectiveness, during competitive 3 vs 3 small-sided and conditioned games (SSCGs) in youth soccer players. Fifteen male players (under 15 yrs, mean age 13.2 ± 1.03 years, mean years of practice: 4.2 ± 1.10 years) from the same club participated in this study. For analysis purposes, on advice from the coaching staff, participants were categorised according to their main team performance role, resulting in sub-samples of 5 defenders (centre-backs = 2 and full- backs = 3), 7 midfielders (central midfielders = 3 and wide…
Performance of Lead-Acid Batteries with Nanostructured Electrodes at Different Temperature
2018
In this work we present innovative lead-acid batteries with nanostructured electrodes, which are cycled in a wide range of temperatures typically of lead-acid commercial batteries (EN 61427-1: 2013). In comparison to parameters usually used to commercial batteries, much more stressful conditions in terms of cut-off, charge/discharge rate and discharge were imposed.
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
"Tentative lessons of experience: Arendt, essayism, and ""the social"" reconsidered"
2014
The article addresses the role of the essay in Hannah Arendt’s theorizing. By paying attention to Arendt’s style, we are better able to draw the full conclusions from the well-known fact that she was not a system-builder but took her bearings from concrete experiences. First, the concept of experience—too often taken at face value—is explicated. It is argued that Arendt’s understanding of the concept cannot be reduced to her personal experiences, but must be read against the background of the common world. A crucial dimension in the incorporation of experiences into the Arendtian political theory is the essayistic style of her writings. The essay, as an experimental and tentative platform,…
Invisible streams : Process-thinking in Arendt
2016
For Hannah Arendt, some of the most distinctive features of the modern age derived from the adoption of a process-imaginary in science, history, and administration. This article examines Arendt’s work, identifying what it calls the ‘process-frame’ in her criticism of imperialism, economy, and the biologization of politics. It discusses an interpretation in which ‘natality’ presents a completely alternative mode of temporality, a resistance to the process-frame. This interpretation, it is argued, needs to be specified by taking into account that political action both interrupts and starts processes of its own. To confine and overcome the negative effects of process-framing, it is important t…
Sterilu jaunu radioaktīvu peptīdu sintēze un to pretvēža aktivitāte in vitro sistēmās
2020
NET audzēji ir visbiežāk diagnosticētā onkoloģiskā saslimšana no visiem vēža veidiem. Krūts vēzis, kas pieskaitāms NET audzējiem, ir biežākā onkoloģiskā saslimšana sievietēm ar vairākiem simtiem tūkstošu jaunu gadījumu katru gadu. Kopš pagājušā gadsimta beigām klīniskajā praksē tiek izmantota audzēju un to metastāžu diagnostika ar radiofarmaceitiskajiem preparātiem. Pēdējos gados onkoloģijā tiek ieviesta teranostika – diagnostika un terapija ar audzējam specifisku peptīdu, kas piesaistīts pie radionuklīda. Ar HA-DOTA-TATE, kas ir somatostatīna analogs, saistīti radionuklīdi paver iespējas pacientiem pieejamai teranostikai. Taču trūkst pētījumu par HA-DOTA-TATE spēju saistīties pie SSTR. Tāp…
L'utilizzo del ferro a Palermo dopo il terremoto del 1726
2016
La ricerca, basata essenzialmente sullo studio di una consistente mole di documenti emersi attraverso nuove indagini archivistiche, mira a indagare gli aspetti tecnici legati agli interventi sul patrimonio architettonico di Palermo successivi al terremoto del 1726, approfondendo il ruolo degli architetti e dei maestri coinvolti nel processo di ricostruzione delle fabbriche colpite e ponendo particolare attenzione alle tecnologie messe in atto facenti ricorso all’uso ferro, indagate attraverso lo studio di alcuni casi esemplificativi. Questo materiale, infatti, trovò in questa occasione diverse applicazioni. L’intervento più frequente fu relativo all’inserimento di catene in ferro in corrisp…

Il contrasto al finanziamento del terrorismo internazionale: tra prevenzione sanzionatoria e punizione preventiva
2020
Il volume propone una ricognizione critica delle recenti politiche criminali di contrasto al finanziamento del terrorismo internazionale. In particolare la normativa multilivello di counter-terrorism financing viene utilizzata come cartina di tornasole per verificare se (e in quale misura) i nuovi modelli repressivo-preventivi di impronta emergenziale, tipici delle legislazioni antiterrorismo, siano funzionali ad un effettivo contrasto del fenomeno. E se la parziale rinuncia ad alcuni presidi di garanzia, in nome di indifferibili esigenze securitarie, travalichi il limite oltre il quale il diritto penale perde i propri connotati tipici, per diventare strumento di lotta contro un nemico. L’i…
