Il sacrificio di Ifigenia fra Ditti-Settimio e Draconzio
2022
L’intervento si propone una disamina dell’episodio di Ifigenia nell’«Orestis tragoedia», presentato e analizzato sia in rapporto alla tradizione classica – in particolare, ovviamente, quella latina – tenuta presente da Draconzio nella delineazione della vicenda e nella presentazione della figura della figlia di Agamennone, sia in rapporto con la tradizione tardo-antica, in particolare con la narrazione di Ditti-Settimio. Attraverso l’analisi dell’episodio in questione, si cerca di mettere in risalto i fattori di continuità e di innovazione nel trattamento del mito di Ifigenia (e dei miti classici in generale) da parte del poeta africano. The intervention proposes an examination of the episo…

Boccaccio, «Ninfale fiesolano» 309, 5-8: per la storia di un tópos fra tradizione classica e suggestioni medievali
2022
Questa nota, alla luce della lettura e dell’interpretazione di un passo del «Ninfale fiesolano» del Boccaccio (309, 5-8), ripercorre la fortuna del motivo della “reciprocità” amorosa e, in particolare, dell’intimo rapporto che fa sì che “due” giovani innamorati, legati da affinità di costumi, età, bellezza, siano come “una” sola persona. Un motivo molto antico, questo, che affonda le sue radici nella tradizione biblica e nella letteratura classica, e che conoscerà ampia fortuna nel Medioevo latino e volgare. Fra i testi che vengono proposti e analizzati si segnalano, soprattutto, le «Metamorfosi» di Ovidio, l’«Ero e Leandro» di Museo, il «Narcissus», il «Pamphilus», l’«Alda» di Guglielmo di…
Application of Hydrogen Peroxide to Improve the Microbiological Stability of Food Ice Produced in Industrial Facilities
2022
This work was aimed to produce an “active” food ice to preserve its microbiological safety over time. With this in mind, ice cubes were processed with the addition of H2O2 to water before freezing. Four food ice productions were performed at the industrial level: one control trial without the addition of H2O2 (0OX) and three experimental trials obtained by adding 4, 8, and 12 mg/L of H2O2 (4OX, 8OX, and 12OX), respectively. After production, all food ice trials were artificially contaminated with 102 CFU/100 mL of water-borne pathogenic bacteria (Escherichia coli ATCC 25922, Enteroccus faecalis ATCC 29212, and Pseudomonas aeruginosa ATCC 27853) inoculated individually. Thawed ice samples we…
Quo plura possis, plura patienter feras. Agamennone modello di sapienza nelle Troiane di Seneca
2022
The paper deals with the quarrel between Pyrrhus and Agamemnon in the Troades, with an analysis of Greek and Latin antecedents, focusing in particular on the characterisation of the Achaean commander. The character of Agamemnon, who embodies the suffering of the defeated, shows a new model of royalty in line with Senecan ideology.

Disposal of green roofs: A contribution to identifying an “Allowed by legislation” end–of–life scenario and facilitating their environmental analysis
2022
The rapid and widespread deployment of green roofs requires the need to address their disposal and to assess the environmental impact of this phase of their life cycle to understand whether their current large-scale application may pose a problem. A review of the literature on green roofs environmental performance (particularly Life Cycle Assessment studies) has highlighted the lack of a standardized, commonly adopted, procedure for determining the treatments, recovery and/or disposal, to be assigned to waste from the removal of green roofs. In this regard, it should be mentioned that there is a lack of ad hoc legislation on the disposal of this technology (to the best of the authors’ knowl…
Optimizing the SYBR green related cyanine dye structure to aim for brighter nucleic acid visualization
2022
In recent years, the studies of RNA and its use for the development of RNA based vaccines have increased drastically. Although cyanine dyes are commonly used probes for studying nucleic acids, in a wide range of applications, there is still a growing need for better and brighter dyes. To meet this demand, we have systematically studied the structure of SYBR green-related cyanine dyes to gain a deeper understanding of their interactions with biomolecules especially how they interact with nucleic acids and the structural components which makes them strongly fluorescent. Herein, five new dyes were synthesized, and their photophysical properties were evaluated. Observations of photophysical cha…
«L’antico come principio di nuova architettura». Il tempo perenne delle opere e dei progetti
2022
Nonostante la raccolta degli scritti e dei progetti di Angelo Torricelli copra un arco temporale di oltre trent’anni (dal 1990 al 2021) essa costituisce una straordinaria narrazione coerente e coesa nella quale si ha chiara la sensazione di come l’oggetto della riflessione sia la connaturata dimensione sincronica dell’architettura tesa a essere, inevitabilmente, espressione di valori atemporali. Non a caso i titoli dei testi di Torricelli, ad iniziare da ciò che ne costituisce la sintesi suprema, l’espressione metonimica per eccellenza — "Il momento presente del passato" — tendono ad essere quasi dei voluti emblematici ossimori. Nella lettura interpretativa dell’antico in architettura propo…
Insufficienza Celiaco Mesenterica
2022
L’insufficienza celiaco-mesenterica (ICM) è una sindrome clinica in cui il sintomo cardine è rappresentato dal dolore addominale che insorge nella fase post-prandiale, e che è provocata dall’inadeguata vascolarizzazione di uno o più settori dell’apparato digerente. Essa insorge per la presenza di lesioni ostruttive a carico delle tre principali arterie splancniche: il tripode celiaco (TC), l’arteria mesenterica superiore (AMS) e quella inferiore (AMI). Esistono due forme di ICM, una acuta e una cronica, che differiscono dal punto di vista fisiopatologico, oltre che per eziologia e clinica, sottolineando peraltro la possibile evoluzione improvvisa da cronica in acuta, fino all’evoluzione in …
Hydraulic Habitat Structure Impacts Risk of Trematode Infection
2022
Abstract— Variability in infection rates of trematodes Diplostomum pseudospathaceum in 0+ rainbow trout Oncorhynchus mykiss under different hydraulic regimes was studied in the experimental setup with regulated flow rates and environmental heterogeneity. The average infection rate in the conditions of the current was 1.5 times less than that in the stagnant water. An increase of the flow rate from 3.2 to 11.3 cm/s did not result in lower infection rates, while the interindividual variability in the infection rate (coefficient of variation) tended to increase along with changing the still-water conditions (20%) to the high flow rate environments (40%) within the experiment. A decrease in th…
Renaissance Itineraries between Nebrodi and Peloritani: Architectural Heritage, History and Technology
2022
Within the general framework of a research Project of Relevant National Interest (PRIN 2017), entitled “The Renaissance in Southern Italy and the Islands: Cultural Heritage and Technology”, the research unit based at Palermo University focused on the inner area that includes Nebrodi and Peloritani mountains, as a quite unexplored and stimulating environment in the specific field of investigation. The scientific relevance of the investigation on “Renaissance itineraries” in this territory, for a deeper understanding of the overall cultural phenomenon in the island, guided this choice, as well as the opportunity to create cultural networks among small local communities, encouraging their sust…
Effect of mucilage edible coating on fresh-cut nectarine cultivar ‘Big Bang’
2022
The mucilage (OFI) obtained from cladodes of cactus pear (Opuntia ficus-indica) is useful to produce natural edible coatings to improve the shelf life of fruits. Edible coatings could be used to extend the shelf life of fresh-cut for products. The aim of this study was to evaluate the effect of (OFI) on quality of ‘Big Bang' nectarine slices. After cutting, nectarine slices were dipped in three different solutions: 1) distilled water, mucilage, glycerol (MC); 2) distilled water, mucilage, glycerol, Tween 20 (TW); 3) distilled water as control (CTR) and were stored for 3, 5, 7 and 12 days at 5°C and 90% RH, in polyethylene terephthalate (PET) packages under passive modified atmosphere condit…
Predicting physical activity change in cancer survivors: an application of the Health Action Process Approach.
2022
Purpose Previous research has not examined the utility of the Health Action Process Approach (HAPA) to predict physical activity (PA) change in cancer survivors. The aim of the study was to investigate the efficacy of a HAPA-based model in predicting temporal change in moderate-to-vigorous physical activity (MVPA) in cancer survivors. Methods Participants enrolled in the Wearable Activity Technology and Action Planning (WATAAP) trial completed validated questionnaires (n = 64) to assess HAPA constructs (action and maintenance self-efficacy, outcome expectancies, action planning, risk perceptions, and intention) and wore an ActiGraph to measure PA at baseline, 12 weeks, and 24 weeks later. D…
L’aggravante dello stalking per l’omicidio e le lesioni personali al vaglio delle Sezioni Unite, tra reato complesso e disattenzioni del legislatore
2022
Come si ricorderà, il D.L. n. 11 del 2009 (conv. in L. n. 38 del 2009), introducendo nel codice penale il delitto di atti persecutori (art. 612-bis), ha al contempo modificato l’art. 576, comma 1, c.p., inserendo tra le aggravanti dell’omicidio doloso l’essere stato commesso dall’autore di atti persecutori nei confronti della stessa vittima. Occorre pure tener presente che tale modifica dell’art. 576 c.p. produce effetti anche sull’art. 585 c.p., che stabilisce che nei “casi previsti dagli articoli 582, 583, 583-bis, 583- quinquies e 584, la pena è aumentata da un terzo alla metà, se concorre alcuna delle circostanze aggravanti previste dall’articolo 576”. Con la sentenza in epigrafe le Sez…

Nascita e formazione di una banca centrale. Sulla Storia della Banca d’Italia di Gianni Toniolo
2022
Questa nota si propone di presentare i temi principali del recente volume di Gianni Toniolo dedicato alla storia della Banca d’Italia negli anni fra la sua fondazione (1893) e la caduta del fascismo (1943). Riprendendo alcuni recenti contributi sulla storia del “central banking”, si mostra come la contrapposizione fra “evoluzione” e “costruzione” di una banca centrale rappresenta un’utile, anche se parziale, chiave per rileggere la storia della Banca d’Italia. Mentre in età giolittiana si realizza una forte affermazione della Banca nella difesa della stabilità monetaria e nel perseguimento di obiettivi di pubblico interesse, negli anni fra le due guerre si ha un progressivo ridimensionament…
Più maestri tra i banchi di scuola primaria
2022
Nei Paesi membri dell’OECD, i maestri di scuola primaria rappresentano una minoranza del corpo docente, per la bassa remunerazione, lo scarso prestigio sociale e lo stereotipo di una professione ritenuta femminile. Nella prima parte di questo contributo, si ricostruiscono le ragioni con cui si spiega la mancanza degli insegnanti maschi nella scuola primaria e si presentano i rimedi che alcuni Paesi hanno tentato di applicare per ridurre la dimensione di questo problema. Nella seconda parte, si presentano i risultati di un’indagine svolta nel 2021 sulla professione di maestro percepita da 71 studenti maschi frequentanti il corso di studi in Scienze della Formazione Primaria presso l’Universi…
Similarity-Based Virtual Screening to Find Antituberculosis Agents Based on Novel Scaffolds: Design, Syntheses and Pharmacological Assays
2022
A method to identify molecular scaffolds potentially active against the Mycobacterium tuberculosis complex (MTBC) is developed. A set of structurally heterogeneous agents against MTBC was used to obtain a mathematical model based on topological descriptors. This model was statistically validated through a Leave-n-Out test. It successfully discriminated between active or inactive compounds over 86% in database sets. It was also useful to select new potential antituberculosis compounds in external databases. The selection of new substituted pyrimidines, pyrimidones and triazolo[1,5-a]pyrimidines was particularly interesting because these structures could provide new scaffolds in this field. T…

La speciale disciplina urbanistica ed edilizia delle opere pubbliche
2022
Le opere pubbliche costituiscono uno degli oggetti principali e più qualificati della ordinaria disciplina urbanistica ed edilizia, cionondimeno ne sono generalmente sottratte. E’ a partire dagli anni Settanta del secolo scorso che vengono via via introdotte leggi di settore che attribuiscono ai procedimenti di localizzazione e realizzazione di varie tipologie di opere pubbliche l’effetto di derogare sia alle previsioni del piano regolatore generale, evitando la procedura ordinaria di variante al piano, sia alla disciplina generale sui titoli abilitativi. Nella stessa direzione si sono mossi i decreti legge n. 77/2021 e n. 36/2022 con riferimento alle opere, agli impianti e alle infrastrutt…
Dominating taxonomic composition of the early life gut microbiota and influencing factors in infants up to seven months of age in Latvia
2022
Abstract It has been hypothesised that the establishment of stable adult microbiota is programmed in infancy, and therefore early life gut colonisation may lead to a lifelong microbiota pattern with significant effects on health. The aim of the study was to analyse the composition of gut microbiota and influencing factors in infants up to seven months of age in Latvia. A cross-sectional study was performed at primary healthcare centres. The parents of healthy infants filled out a questionnaire and brought the child’s faecal sample. 16 rRNS gene sequencing was performed to identify the bacterial taxonomic units. The composition of gut microbiota was compared between children with different r…
Musical identities in action:Embodied, situated, and dynamic
2022
This article provides a critical overview of musical identities as a research topic. A broad distinction between identities in music (IIM) and music in identities (MII) highlights how musical engagement is central to identity construction. These concepts are integrated with recent advances in psychological theory derived from enactive cognition (4E cognition) to propose a new framework for understanding musical identities, Musical Identities in Action (MIIA). This framework foregrounds musical identities as dynamic (constantly evolving, dialogical, and actively performed), embodied (shaped by how music is physically expressed and experienced), and situated (emergent from interaction with s…

Il corpo delle regine
2022
La medievistica più recente, sulla scia di nuove questioni volte a indagare la condizione reginale da prospettive diverse e originali, ha tracciato un profilo sempre più sfaccettato delle regine. In questo saggio ci proponiamo di guardare alla dimensione più esterna, materiale, e al contempo più intima, il corpo, che ha una sua storia e fa parte della storia, la costituisce non diversamente dalle strutture sociali, economiche, e dalle rappresentazioni mentali. Il corpo di una regina associa a un corpo reale, fisico, fatto di bellezza, fecondità, cure e pratiche di mantenimento della salute, di sterilità e malattia, un corpo immaginario fissato al momento della morte nel gisant che ne traman…
Himera nella seconda metà del V secolo a.C. aspetti della cultura materiale: case, servizi da tavola, riunioni conviviali
2022
After a re-examination of the 5th century BC housing culture at Himera in comparison with the housing culture of the same period in Athens, four Athenian red-figured and black glazed pottery assemblages are examined by comparing them with similar contexts from housing districts in Himera, in order to reconstruct as far as possible, the dinner services for convivial meals that involved the consumption of wine, both in formal meetings, both in everyday contexts. Finally, the stratigraphic context of five red-figured craters found in Himera is taken into consideration, re-examining the associations with other ceramic finds with the aim of reconstructing their contexts of use and the functions …
Diversity and composition of the microbiome associated with eggs of the Southern green stinkbug, Nezara viridula (Hemiptera: Pentatomidae).
2022
Although microbial communities of insects from larval to adult stage have been increasingly investigated in recent years, little is still known about the diversity and composition of egg-associated microbiomes. In this study, we used high-throughput amplicon sequencing and quantitative PCR to get a better understanding of the microbiome of insect eggs and how they are established using the Southern green stinkbug Nezara viridula (L.) (Hemiptera: Pentatomidae) as a study object. First, to determine the bacterial community composition, egg masses from two natural populations in Belgium and Italy were examined. Subsequently, microbial community establishment was assessed by studying stinkbug e…
κ-Carrageenan and PVA blends as bioinks to 3D print scaffolds for cartilage reconstruction.
2022
3D printing of polymeric scaffolds and autologous stem cells is a promising tool for damaged facial cartilage reconstruction surgeries. To this end, suitable bioinks are needed to generate scaffolds with the required morphological and functional features. We formulated hydrogel bioinks using k-Carrageen (kC) and poly(vinyl alcohol) (PVA) in three different weight ratios. The kC gives the systems the ability to undergo rapid sol-to-gel transitions upon cooling from 60 °C and above to body temperature, while the PVA is used as rheology modifier and porogen. The latter is crosslinked after molding or printing by freeze-thaw cycling for 1 day (FT1) or 5 days (FT5). To select the most suitable f…

Ag5 nanoclusters with dual catalytic antiradical activities
2022
Silver nanoclusters of five atoms (Ag5) display outstanding catalytic activities for the deactivation of radicals. Using 2,2-diphenyl-1‑picrylhydrazyl (DPPH) radical as a model system, we observed a fast radical reduction to DPPH anions using only [Ag5] 3 to 4 orders of magnitude less than [DPPH]. Moreover, nanoclusters remain stable at the end of the reaction, and can deactivate again DPPH radicals at the same rate, indicating that they act as anti-radical catalysts. The radical scavenger catalytic activity of Ag5 proceeds selectively through the oxidation of methanol (used to dissolve the radical) to formaldehyde, which is supported by DFT calculations. The obtained catalytic rate constan…

Ernesto Rossi e La Riforma Sociale (1926-1930). La carriera interrotta di un economista politico
2022
Con questo saggio si intende ricostruire la breve ma intensa fase di collaborazione di Ernesto Rossi con La Riforma Sociale, prestigiosa rivista di economia e scienze sociali fondata da Francesco Saverio Nitti nel 1894 e diretta da Luigi Einaudi dal 1908. Fra il 1926 e il 1930 Rossi è autore di sette lunghi saggi su tematiche di finanza pubblica, economia applicata e statistica economica che sono stati relativamente trascurati dalla storiografia. La rilettura di questi contributi consente di approfondire alcuni momenti centrali nella sua formazione di economista. In particolare: l’influenza di Einaudi e di De Viti de Marco; la predilezione per un approccio empirico all’analisi economica; la…
The effects of grazing history, soil properties and stand structure on the communities of saprotrophic fungi in wood-pastures
2022
Wood-pastures are threatened anthropogenic biotopes that provide habitat for an extensive group of species. Here we studied the effect of management, grazing intensity, time since abandonment, historical land-use intensity, soil properties and stand conditions on communities of saprotrophic fungi in wood-pastures in Central Finland. We found that the proportion of broadleaved trees and soil pH are the major drivers in the communities of saprotrophic fungi in these boreal wood-pastures. In addition, tree species richness, soil moisture, historical land-use intensity and time since abandonment affected the communities of saprotrophic fungi. Current management or grazing intensity did not have…
Pelkkä ekologinen kompensaatio ei takaa ekologisesti kestävää maankäyttöä
2022
Uudistuvan luonnonsuojelulain (HE 76/2022) myötä ekologinen kompensaatio on noussut Suomessa ajankohtaiseksi aiheeksi. Ekologinen kompensaatio on kiistelty aihe niin Suomessa kuin kansainvälisesti. Jonne Hytönen ja Anna-Kaisa Tupala (2022) nostivat Alue ja ympäristö -lehden numerossa 1/2022 julkaistussa kirjoituksessaan ansiokkaasti esiin ekologisen kompensaation riskejä ja mahdollisuuksia ekologisesti kestävän maankäytön suunnittelun näkökulmasta. Yksinkertaistaen heidän mukaansa kompensaatio palvelee ”reformistista”, sallivaa suunnittelua, joka voi mahdollistaa ympäristöä heikentäville hankkeille ohituskaistan tai lupa-automaatin. Vaihtoehtoisesti, tiukat reunaehdot huomioiden, kompensaat…
Interpersonal work resources and school personnel well-being before and after lockdown during the first phase of the COVID-19 pandemic in Finland
2022
This two-wave mixed-methods study used the job demands and resources model to examine the effects of the COVID-19 pandemic on school personnel's work well-being (including burnout, work engagement, and sense of belonging) in spring 2020 in Finland in particular with respect to collegial relationships (respectful engagement) and leadership support. A pre-lockdown survey was administered prior to the pandemic (in January–February, n = 437) and a post-lockdown survey was administered after the two-month lockdown (at the end of May, n = 270). At post-lockdown, the school personnel reported, on average, more exhaustion, less work engagement (measured as enthusiasm and energy at work), and a decr…
