Maturation of critical technologies for the DEMO balance of plant systems
2022
The Pre-Concept Design (PCD) of the Balance of Plant (BoP) systems of the EU-DEMO power plant is described in this paper for both breeding blanket (BB) concepts under assessment, namely the Water Cooled Lithium Lead (WCLL) BB and the Helium Cooled Pebble Bed (HCPB) BB. Moreover, the results of a preliminary evaluation of a number of BoP variants are discussed. This paper outlines the steps of the BoP design development, highlighting the project objectives and the strategy for their achievement under the very challenging requirements which include, among others, the intermittent nature of the DEMO plasma heat source. The main achievements during the PCD Phase will be reported together with t…
Nella città proibita. Conoscibilità, accessibilità e progetto come condizioni per la valorizzazione e il riuso del patrimonio fragile dei beni confis…
2022
In relazione ad una ricerca internazionale volta ad indagare modi di costituzione e di crisi del Pubblico, inteso come insieme di edifici, spazi pubblici, funzioni, processi e pratiche, l’articolo discute la fragilità e la marginalità intrinseche e di fruizione del patrimonio dei beni confiscati, inteso come terzo patrimonio, riconducendole alle sue conoscibilità e accessibilità. Facendo riferimento al territorio comunale di Palermo, la città europea con il più alto numero di beni confiscati alla criminalità mafiosa, l’articolo argomenterà dapprima in termini generali il rapporto fra la frammentazione e l’inadeguatezza dei processi di inventario e la sostanziale inconsapevolezza che consegu…
Surface water RO permeate remineralization through minerals recovery from brines
2022
Assisted-Reverse Electrodialysis (A-RED) technology was applied following reverse osmosis (RO) of a surface water resource in order to recover minerals from its brine and directly remineralize the RO unit's permeate. Four different sets of cation/anion exchange membranes were benchmarked using single- and mixed-salts synthetic solutions as well as real brine and permeate streams produced from three-stage reverse osmosis applied to Seine River water. The process, operating under equal permeate and brine channel flows (2 cm/s velocities) and applied voltage varying from 0 to 10 V, showed viable remineralization results. Optimal recovery at 10 V applied allowed increasing permeate mineral cont…
Robotic-assisted right colectomy. Official expert recommendations delivered under the aegis of the French Association of Surgery (AFC)
2022
: Twenty-seven experts under the aegis of the French Association of Surgery (AFC) offer this reference system with formalized recommendations concerning the performance of right colectomy by robotic approach (RRC). For RRC, experts suggest patient installation in the so-called "classic" or "suprapubic" setup. For patients undergoing right colectomy for a benign pathology or cancer, RRC provides no significant benefit in terms of intra-operative blood loss, intra-operative complications or conversion rate to laparotomy compared to laparoscopy. At the same time, RRC is associated with significantly longer operating times. Data from the literature are insufficient to define whether the robot f…
Design e narrazioni
2022
Il testo nasce dall’esigenza di mettere a fuoco le implicazioni cognitive, metodologiche e progettuali del concetto di narrazione, sempre più ricorrente nella nostra esperienza quotidiana soprattutto per le molteplici forme di comunicazione e di produzioni culturali che vi si ispirano; si tratta di un concetto che anche nella riflessione teorica e nella progettualità del design sta alimentando dimensioni fortemente innovative ed evolutive nella costruzione, comunicazione di significati, contenuti immateriali, esperienze e valori emozionali che si sovrappongono e s’intrecciano all’espressione tangibile e funzionale degli oggetti, degli artefatti comunicativi, degli spazi. Si propone un perco…
Indigon sinisestä kokenillin punaiseen : tekstiilivärjäyksessä käytettyjen luonnonväriaineiden tuonti Suomeen (1791–1856)
2022
Tutkimme ulkomaisten luonnonväriaineiden tuontia Suomeen 1790-luvun alusta 1850-luvun puoliväliin. Ajankohtaa voidaan luonnehtia murroskaudeksi väriaineiden käytön historiassa. Selvitämme mitä väriaineita Suomeen tuotiin, millaisia määriä, minneniitä tuotiin sekä mistä satamista väriainelastit olivat lähtöisin. Lähdeaineistomme perustan muodostavat Tanskan Juutinrauman tullitilit, joista on koostettu suomalaisia satamia koskeva tietokanta (FIN-STRO: 1560/1791–1856). Lähdepohjaa on täydennetty muulla tilastoaineistolla sekä laadullisella materiaalilla, kuten värjäysoppailla ja Kansalliskirjaston digitaalisella sanomalehtiarkistolla. Tutkimme erityisesti sinistä, punaista ja keltaista väriä t…
The alliance-outcome association in group interventions: A multilevel meta-analysis.
2022
Objective: The therapeutic alliance has been studied in group interventions, but its relationship to patient outcome is still controversial. This study systematically reviewed the association of both the member-leader and member-group alliance with patient outcomes, and assessed the effects of several theoretically informed moderators. Method: A three-level meta-analysis was conducted on 57 studies to disentangle within- and between-study variability in the alliance-outcome association. Results: The overall effect size of the unconditional model was r = -.259 (95% CI: -.302, -.214; p < .001), whereas the correlation between alliance and outcome based on the three-level meta-analytic mode…
3D DCE-MRI Radiomic Analysis for Malignant Lesion Prediction in Breast Cancer Patients
2022
Rationale and Objectives: To develop and validate a radiomic model, with radiomic features extracted from breast Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) from a 1.5T scanner, for predicting the malignancy of masses with enhancement. Images were acquired using an 8-channel breast coil in the axial plane. The rationale behind this study is to show the feasibility of a radio-mics-powered model that could be integrated into the clinical practice by exploiting only standard-of-care DCE-MRI with the goal of reducing the required image pre-processing (ie, normalization and quantitative imaging map generation).Materials and Methods: 107 radiomic features were extracted from a …
Patterns of action transitions in online collaborative problem solving : A network analysis approach
2022
AbstractIn today’s digital society, computer-supported collaborative learning (CSCL) and collaborative problem solving (CPS) have received increasing attention. CPS studies have often emphasized outcomes such as skill levels of CPS, whereas the action transitions in the paths to solve the problems related to these outcomes have been scarcely studied. The patterns within action transitions are able to capture the mutual influence of actions conducted by pairs and demonstrate the productivity of students’ CPS. The purpose of the study presented in this paper is to examine Finnish sixth graders’ (N = 166) patterns of action transitions during CPS in a computer-based assessment environment in w…
Bisogni e opportunità in tempi di pandemia a fronte del partenariato pubblico-privato: il caso della Fiera del Mediterraneo a Palermo
2022
The Fair of the Mediterranean in Palermo has been an unresolved urban issue since the interruption of activities in 2008 and the closure of the Fair Authority. The Lisca Bianca association - to which the municipal administration has entrusted one of the pavilions - began to question, together with other territorial actors present in the Fair and in the 8th Circoscrizione, the management and future of the space, promoting, with the collaboration of the university, the first phase of a participatory process to imagine its redevelopment. The quarantine interrupted the work, which did not go beyond the first meeting (during which a World Café and Planning for Real were held). The needs expresse…
Le Officine Ducrot, un esempio di organizzazione del lavoro dell'industria palermitana tra il XIX e il XX secolo
2022
Le officine Ducrot sono un'importante testimonianza del fiorente passato imprenditoriale palermitano che ha avuto un ruolo centrale tra la fine dell'Ottocento e i primi del Novecento del secolo scorso per il carattere internazionale e innovativo di una attività, nata da un piccolo mobilificio, trasformata in pochi anni in un prestigioso atelier artigianale, fino a diventare una società di produzione industriale con una affermazione artistica e commerciale tale da ottenere la quotazione in Borsa. I motivi del grande successo sono numerosi: il sodalizio tra il proprietario, Vittorio Ducrot, e l'architetto Ernesto Basile; la produzione di raffinati e moderni arredi, caratterizzati da un mix tr…
L'ordine, dal centro ai margini: a proposito della ripubblicazione di due testi di Costantino Mortati
2022
In questo articolo, offro una ricostruzione della concezione dell’ordinamento giuridico, dello sta- to e della costituzione materiale di Costantino Mortati, mostrando la evoluzione da essa subita nel corso degli anni. Mi soffermo in particolare su due aspetti: sulla natura di “fatto normativo” della volontà delle forze politiche dominanti che, secondo Mortati, sostiene la costituzione ma- teriale dello stato; e sul modo in cui Mortati applica la sua concezione alla fase di formazione e di mutamento della costituzione materiale, e ai periodi di indebolimento dell’unità politica. In this article I propose a reconstruction of Costantino Mortati’s view of the legal order, the state and the mate…
[Re]Constructing Lost Realities, Possible Worlds and Future Perspectives Through Digital and Public Humanities
2022
The 2022 volume of Magazén is devoted to practical aspects in the Digital and Public Humanities. The first issue is thus entitled [re]constructions, focusing on the wide array of practices that prospered in our wide field for [re]configuring lost realities, [re]creating long gone dimensions, [re]building likely scenarios, [re]considering exhibition settings, and [re]covering disappeared traces of historical and cultural value.
Parasite–copepod interactions in Svalbard: diversity, host specificity, and seasonal patterns
2022
AbstractCopepods of the genera Calanus and Pseudocalanus are important components of Arctic marine ecosystems. Despite the key roles of these zooplankters, little is known about the organisms they interact with most intimately, their parasites and symbionts. We applied metabarcode sequencing to uncover eukaryotic parasites present within these two copepod genera from three areas around the high Arctic archipelago of Svalbard. Ten distinct parasite groups were observed: four different Apostome ciliates, four different dinoflagellates (Chytriodinium sp., Ellobiopsis sp., Thalassomyces sp., and Hematodinium sp.), a Paradinium sp., and a trematode. Apostome ciliates closely related to Pseudocol…
Worldwide trends in population-based survival for children, adolescents, and young adults diagnosed with leukaemia, by subtype, during 2000–14 (CONCO…
2022
BACKGROUND Leukaemias comprise a heterogenous group of haematological malignancies. In CONCORD-3, we analysed data for children (aged 0-14 years) and adults (aged 15-99 years) diagnosed with a haematological malignancy during 2000-14 in 61 countries. Here, we aimed to examine worldwide trends in survival from leukaemia, by age and morphology, in young patients (aged 0-24 years). METHODS We analysed data from 258 population-based cancer registries in 61 countries participating in CONCORD-3 that submitted data on patients diagnosed with leukaemia. We grouped patients by age as children (0-14 years), adolescents (15-19 years), and young adults (20-24 years). We categorised leukaemia subtypes a…
Tra spazi e funzioni. La crisi dello spazio urbano prima, durante e dopo il Covid-19
2022
Fin dagli albori dell'età urbana, i problemi e i valori dell'insediamento urbano sono variati notevolmente nel corso dei secoli, ma l'importanza della struttura spaziale urbana non è mai stata cancellata. Oggi la città è ancora al centro della nostra civiltà, ma le relazioni tra sistemi socio-ecologici nidificati sono più complesse perché le interazioni uomo-ambiente non sono bidirezionali. L'ascesa dell'Antropocene, una nuova era dirompente ed erosiva causata dall'Umanità, comporta una crisi economica, demografica e ambientale, come dimostrano le attuali pandemie. Il mese scorso le notizie ci hanno detto che il nuovo coronavirus non è stato il primo caso di virus che salta la specie, raggi…
Designing knowledge construction in pre-service teachers’ collaborative planning talk
2022
In this paper, we report on a qualitative study of student teachers’ collaboration in planning and implementing a course that integrated physics and the Finnish language. Audio-recorded planning sessions and interviews were examined using qualitative content analysis, first, to discover what kind of space for knowledge construction student teachers designed for learners and, second, to identify the characteristics of their collaboration in developing a new cross-disciplinary pedagogical practice. The analysis revealed challenges in integrating meaning-making resources for knowledge construction; especially the role of language remained mostly invisible. This indicates a need to develop teac…
Reasoning and proving in Algebra. Examples from 8th grade school mathematics textbooks in Italy
2022
Some research studies concerning the didactics of Algebra discuss how learning to solve problems using symbolic algebraic language can be hard for students (Bohlmann et al., 2014; Palm, 2009). Students, in fact, have often difficulty to learn the ways in which the sym- bols should be manipulated to argue or to prove an assertion in order to reach a problem solu- tions. Although many studies conducted by mathematics educators discussed important contri- butions to this subject (e.g. Arzarello, Robutti & Bazzini, 2005; Boero, 2001; Carraher, Schliemann, Brizuela & Earnest, 2006; Lins & Kaput, 2004; Ursini & Trigueros, 2001), not many analysis were conducted on the role of the …
Características de la desinformación en redes sociales. Estudio comparado de los engaños desmentidos en Argentina y España durante el 2020
2022
Este trabajo estudia los principales rasgos de las desinformaciones que circularon en redes sociales en Argentina y España durante el año 2020, así como sus similitudes y diferencias. La investigación aplica un análisis de contenido de siete variables a 402 engaños desmentidos en ambos países por los medios verificadores Chequeado y Newtral. En concreto, se estudian las fuentes de las desinformaciones, su tipología, los protagonistas y sus atributos, su adscripción temática, las emociones a las que apelan y los rasgos populistas que presentan. Los resultados evidencian el predominio de (a) fuentes anónimas en ambos países, de fuentes reales mediáticas en Argentina y de fuentes políticas sup…
Intensificatori e soggettificazione in latino: sulla grammaticalizzazione di maxime
2022
The aim of this paper is to investigate the grammaticalization path of the intensifying adverb maxime in Early Latin, within the perspective of the so-called ‘subjectification’ theory. Despite the difficulty of drawing discrete boundaries within the multifunctional category of adverbs, the semantic, syntactic and pragmatic analysis of maxime across different contexts of use allows us to identify at least three main functions of this adverb in early Latin texts, mostly in the Roman comedy of Plautus and Terence. In particular, adopting the perspective of the Functional Discourse Grammar, it is shown that maxime is used as (i) degree adverb, which modifies a large range of elements acting at …
From Image to Investigation 3D Reconstruction with Perspective Restitution
2022
The memory of hundreds gone buildings is preserved by few photographic images. Perspective restitution with digital representation tools can be used today to reconstruct these buildings directly in 3D space. Digital representation has overcome many limitations that affected perspective restitution in the pre-digital era. In this paper the inner space of the church of San Michele in Trapani, destroyed at the end of the 50’, is reconstructed with the aid of three period photographic images. Some architectural elements that escaped destruction and are today located in a new church near Trapani have been surveyed with laser scanning and SfM photogrammetric techniques. Surveyed elements provided…
Just transition principles and criteria for food systems and beyond
2022
In this article, we propose a framework of principles and criteria for just transitions in food systems. Climate mitigation activities are urgently needed in food systems, but can have damaging social, environmental, economic, and health impacts. Consequently, food system transitions can cause significant side effects across and beyond food systems, aggravating existing inequalities and unsustainabilities, causing new ones, or hampering equal engagement in the transition itself. Thus, justice questions stand at the core of assessing decarbonization pathways and policies and must link to other sectors as well: Who bears the costs and who enjoys the benefits of the transitions? Can transition…
Old controversies and new data: assessing again the polychrome vases from Centuripe
2022
The necropolises of the hill town of Centuripe (EN) in Sicily have been looted since the nineteenth century for obtaining objects that were attractive for antiquities collectors, such as Hellenistic terracotta figurines and the brightly polychrome vases produced by local artisans (known as “Centuripe vases”) that today are scattered throughout a number of museums and private collections over the world. Until recent times, quite many vases have been considered doubtful and sometimes revealed as forgeries. Some “restorers” working in the dark circuit were able either to reproduce the shapes and decorations of ancient vases or to “refresh” their painted surfaces indeed: the interplay between g…
Agile logic for SaaS implementation: Capitalizing on marketing automation software in a start-up
2022
The emergence of Software-as-a-Service (SaaS) has facilitated agile technology implementation that focuses on iterative adaptations via learning by doing rather than the realization of a predesigned implementation plan. This study conceptualizes such an agile approach and explicates its operationalization via a four-year qualitative case study of a business-to-business (B2B) start-up firm’s implementation of a HubSpot marketing automation (MA) SaaS. The study shows how agile implementation continuously introduces adaptations to SaaS features and organizational routines for improving their mutual fit given the organization’s goals. The study also contributes to theory by offering a novel fra…
Storie di oggetti (e di sogni) perduti. Musei contemporanei per ritrovarsi
2022
What happens to humanity discarded by history? To the broken dreams (of love and life)?What to do with the objects that fill our life as "fragile ruins" of a dream lost forever? The article, looking at various contemporary projects of permanent museums and temporary exhibitions, intends to outline and lead a reflection on the radical paradigm change that intervenes in the exhibition processes and in the strategies of emotional engagement within contemporary museological policies. Conceived as places of encounter and relationship, museums are open to communities and individual stories. In particular, the emotion of lost guided the constitution of collections of objects, in a series of exhibi…
A comprehensive multi-scale model for bipolar membrane electrodialysis (BMED)
2022
Bipolar membrane electrodialysis (BMED) is a technology combining solute and solvent dissociation to produce chemicals. In the recent decades, it has been typically studied for the production of valuable acid and base solutions from salt streams. Although many works have been devoted to the experimental investigation of BMED, only a few efforts have focused on its mathematical modelling. In the present work, a comprehensive process model based on a multi-scale approach with distributed parameters is presented for the first time. Five models related to four different dimensional scales were fully integrated to form a comprehensive tool. The integrated model was developed by using the process…
Additional Evidence for a Pulsar Wind Nebula in the Heart of SN 1987A from Multiepoch X-Ray Data and MHD Modeling
2022
Since the day of its explosion, supernova (SN) 1987A has been closely monitored to study its evolution and to detect its central compact relic. In fact, the formation of a neutron star is strongly supported by the detection of neutrinos from the SN. However, besides the detection in the Atacama Large Millimeter/submillimeter Array (ALMA) data of a feature that is compatible with the emission arising from a proto-pulsar wind nebula (PWN), the only hint for the existence of such elusive compact object is provided by the detection of hard emission in NuSTAR data up to ~ 20 keV. We report on the simultaneous analysis of multi-epoch observations of SN 1987A performed with Chandra, XMM-Newton and…

Shielding families’ experiences during the COVID-19 pandemic: a review across the UK and Italy
2022
As communities have gone into lockdown to stop the worldwide spread of the COVID-19 pandemic, the mass efforts to save lives has put some people more at risk than others, and in their own homes. Starting with a comparison between Italy and the UK, this review examines the impact of pandemic measures for those shielding families who are affected by abusive relationships and those who, with health and social care needs, are considered at high risk of serious consequences if they are exposed to COVID-19 measures. Focusing on an increased number of DV cases reported, we explore the impact of pandemic measures on vulnerable people and families through a review on this topic, that comprises early…
Analisi delle condizioni e dei percorsi di inserimento dei prodotti ludico digitali nel settore del turismo culturale e possibili scenari di sviluppo…
2022
Con una pervasività ed una velocità inusitate, la disintermediazione ha impresso il suo sigillo sulla nostra era. È il principio su cui si fonda tutta la tecnologia dell’universo blockchain che, sostituendo tutte le istituzioni centrali con reti orizzontali, aperte e condivise di blocchi, valida le operazioni senza bisogno di controllori, notai o terze parti (di qui anche il discusso fenomeno dell’NFT, “non-fungible token”, permette di comprare un’opera senza il bisogno di una galleria/ un mediatore). Una svolta di enorme impatto che, dalla verticalità centralizzata con cui veniva dispensata la cultura dei corpi intermedi, giunge all’orizzontalità decentralizzata che connette gli individui,…
Socio-economic deprivation and COVID-19 infection: a Bayesian spatial modelling approach
2022
Il presente articolo ha l’obiettivo di analizzare l’effetto della deprivazione socio-economica sull’incidenza da COVID-19 a livello sub-comunale. Grazie alla disponibilit`a di informazioni sui tassi di incidenza mensili da COVID-19 a livello di sezione di censimento per i due comuni di Palermo e Catania (Italia), viene pro- posto l’utilizzo di un modello spaziale Bayesiano con distribuzione binomiale zero- inflated. I risultati mostrano un’associazione tra livelli di deprivazione e incidenza da COVID-19 nei due comuni, controllando per la struttura spaziale delle unit`a areali considerate. Alla luce dei risultati, si rendono necessarie azioni di politica sanitaria focalizzando gli intervent…

L’anfiteatro romano dell’Urbe panormita tra paradigmi congetturali e possibili palingenesi
2022
Come il sottotitolo del libro di Giuseppe Ferrarella (Persistenza delle forme nell'architettura della città) eloquentemente dimostra, l’indagine compiuta svela una precisa prospettiva epistemica che si focalizza su una singola parte della città, il quartiere della Loggia, il cui disvelamento di senso va a modificare il complesso del sapere del “tutto”. Una conoscenza basata principalmente sul processo cognitivo di natura abduttiva o ipotesi di retroduzione, trattandosi di una inferenza del terzo tipo. Un procedimento logico, quindi, analogo alla deduzione e all’induzione, ma che cerca di spiegare i fatti osservati inferendo la causa dall’effetto, aggiungendovi sempre dell’altro, divenendo a…
Il Mare di mezzo: storie di naviganti, di lotta per il diritto e di luci nel buio della frontiera
2022
This paper analyses the way in which, and the reasons why, the Mediterranean Sea, from being a limes between lands, has become the frontier we know today: the space of an emblematic struggle for law and rights, which contrasts the policies of governments with the forced movements of people in migration and with civil society organizations that try to promote and protect fundamental rights. In this context, the direct experience of some search and rescue missions in the Mediterranean Sea has been used to highlight the extent of this conflict with respect to the violation of the national and domestic legal frameworks carried out by the European states, Italy in the lead, also through the invo…
The role of eating disorders features, psychopathology, and defense mechanisms in the comprehension of orthorexic tendencies
2022
Abstract Purpose Recent studies pointed out the importance to distinguish orthorexia nervosa (ON) from non-problematic forms of interest with healthy eating. This distinction needs to be further explored since it may favor a better comprehension of the relationship between orthorexic behaviors and psychopathology and lead to an improved understanding of the psychological processes implicated in ON. Therefore, the aim of the current study was to investigate the associations between ON and the core features of eating disorders (EDs), psychopathological symptoms and defense mechanisms, by differentiating three groups of individuals: an ON symptoms group, a healthy-eating control group, and a n…
Au sein du CNRS, un Observatoire de l’environnement nocturne pour accompagner la territorialisation de la lutte contre la pollution lumineuse
2022
National audience; Jusqu’à présent, les politiques de préservation de l’environnement nocturne peinent à saisir l’ensemble des effets négatifs de la lumière artificielle nocturne (ALAN). La question de la qualité de l’environnement nocturne n’est ainsi que partiellement traitée. D’une part, les enjeux liés à l’efficience énergétique des systèmes techniques d’éclairage et à la qualité du ciel étoilé occultent quasi systématiquement les enjeux écologiques et sanitaires de la préservation de l’obscurité. D’autre part, un fossé considérable persiste entre des solutions de mitigation technique à l’échelle locale et la mise en œuvre, à des échelles plus larges, de zonages construits par et pour d…
