Organisations supporting cardiac arrest survivors: An exploratory survey of organisational structures and activities
No full textBackground: Cardiac arrest survivors have diverse needs beyond healthcare, including spirituality, social networks, practical, legal, and economic matters, highlighting the need for community-based support. While some non-governmental organisations support various patient groups, little is known about those dedicated to cardiac arrest survivors. The European Resuscitation Council (ERC) conducted a survey to identify and understand these organisations’ structures and activities. Methods: An internet survey developed by the ERC was disseminated through media channels, national resuscitation councils, and social networks. Responses were verified against publicly available information to confirm declared activities and sustained support efforts. Organisations were classified based on whether their primary focus was on cardiac arrest survivors or if support was a secondary activity. Results: Of fifty-six responses, eight organisations were identified as providing structured, continuous support. Six primarily focused on cardiac arrest survivors, while two had a broader scope. Most were established after 2000, with six in Europe and two in the United States. Membership ranged from 520 to 3000 survivors. Common activities included peer support and distributing information materials. Connections with healthcare systems varied, with three reporting none. Only two were represented in their national resuscitation councils (NRCs). Conclusions: Organisations supporting cardiac arrest survivors are scarce but address important unmet needs. However, public presence is limited, and ties with institutions remain weak. Strengthening collaborations with healthcare providers, NRCs, and stakeholders could enhance support networks and improve long-term post-resuscitation care
Dalla pietas fraterna alla devotio uxoria: riuso catulliano nell’elegia funebre di Giovanni Pontano (Tum. II 25)
No full textIl presente studio analizza le strategie di imitatio e risemantizzazione del modello catulliano
nella lirica funebre di Giovanni Pontano, con un’indagine specifica sul Tum. II 25, dedicato alla moglie
Ariadna. Collocandosi nel dibattito umanistico sulla ricezione dei classici e sulla tradizione del liber catulliano
nel Quattrocento, la ricerca adotta una metodologia filologico-letteraria. Attraverso una lettura ravvicinata
del testo e un sistematico confronto intertestuale con il carme 101 di Catullo, nonché con altri auctores
(Virgilio, Ovidio, Tibullo), si intende dimostrare come Pontano operi una profonda metamorfosi del
modello. L’analisi evidenzia la trasposizione della pietas fraterna catulliana in una inedita forma di devotio
uxoria, un sentimento che coniuga la memoria del lusus amoroso, la celebrazione del sodalizio domestico
e la speranza di un ricongiungimento ultraterreno. I risultati principali mostrano come Pontano, pur mantenendo
precisi calchi lessicali e strutturali (l’incipit interrogativo, la formula di congedo), svuoti il modello
della sua tragica finalità. Il monologo desolato di Catullo si trasforma in un dialogo intimo e consolatorio
con la defunta, percepita come ancora viva. Il contributo del saggio consiste nell’identificare in Tum. II 25
non una semplice ripresa, ma una complessa operazione di adattamento culturale e personale che arricchisce
il genere dell’epicedio umanistico, fondendo la sensibilità classica con l’esperienza biografica e la spiritualità
moderna
Effect of Microscale Fabrication on Multi-Directional Mechanical Properties of Additively Manufactured Poly Lactic Acid With Grid Infills
No full textIn additive manufacturing, infill patterns have a significant impact on both printing time and mechanical performance, creating a necessary trade-off between the two from an industrial perspective. This study aims therefore to find an easy-to-handle procedure for rapid evaluation of the influence of infill density and raster angle on the elastic properties of 3D-printed components, from the perspective of their adoption in the industrial process of component design. In particular, the study's goal is to predict the elastic modulus in three directions. Tensile tests were carried out on bulk specimens according to ISO 527 to determine the elastic properties of 3D-printed PLA necessary for the numerical analysis. Cubic specimens were then manufactured with three densities (20%, 40%, and 60%) and two raster angles (-45 degrees/45 degrees and 0 degrees/90 degrees). Quasi-static compression tests were conducted on those specimens to assess their homogenized elastic behavior in three directions. One important result of the experimental phase was the relationship between Young's modulus (E) in the three directions. The average of E in directions 1 and 2 (build plate) is named E-1,E-2 and on the build-up directions is E-3, for alpha = 0 degrees/90 degrees was E-1,E-2 = 0.8E(3) and for alpha = -45 degrees/45 degrees was E-1,E-2 = 0.28E(3). Three finite element models were developed and run with the elastic properties determined by tensile tests, namely: (a) a shell model (SHL) where the internal and external walls of the specimens were modeled using shell elements with the nominal geometry; (b) a solid model (SLD) with the nominal geometry and (c) a nonuniform section model (NUS) in which the geometry was taken from microscope image to account for manufacturing imperfections. The difference between simulation and experiment for SHL was 19%, SLD was 15%, and NUS was 13%, indicating an overall good correspondence and, at the same time, that the real geometry resulting from the manufacturing process has a non-negligible impact on the homogenized value. Besides validating the values and relationships, FEM elucidated which sections of the cubes experienced stress and contributed to stiffness under various patterns and loading scenarios

No full textGreen Investment and Productivity Dynamics
No full textThis paper reviews existing definitions and measurement efforts to capture the extent of green technological investment, and it provides a measurable definition of green capital asset for a sample of 18 OECD countries from 2004 to 2020. A main goal of this paper is to assess the contribution of green technological capital to productivity growth also taking into account the effects of tightening environmental regulations. The econometric results suggest that: (1) an increase in green technological capital stock generates medium-term productivity gains; (2) stricter environmental regulations boost, rather than hinder, productivity growth. Furthermore, the empirical findings corroborate previous evidence that more stringent nonmarket policies, such as emission limits, can stimulate innovation, thereby contributing to positive productivity returns. The paper provides also some policy insights highlighting the critical role of green technological investment in promoting sustainable growth while mitigating climate change
Baboons at a Crossroads: Hybridisation Events and Genomic Links of Central Mozambique's Baboons With Papio Neighbors
No full textObjectivesHybridisation plays a critical role in species evolution and is widespread among primates, particularly in the genus Papio. Several baboon hybridisation zones have been identified in Africa, with Gorongosa National Park in Mozambique being notable for chacma baboons exhibiting phenotypic and genomic traits of both chacma and yellow baboons. This study builds on earlier research by leveraging new genomic data to refine our understanding of the relationships between Central Mozambique baboons and other baboon populations, focusing on chacma, yellow, and kinda baboons.Materials and MethodsWe analyzed uniparental genetic markers alongside autosomal and X chromosome variants, incorporating unpublished low-coverage genomes from fecal samples collected in Central Mozambique. These data were compared with the broader genomic landscape of Papio baboons based on recent surveys.ResultsThe analysis of uniparental markers suggests a time to the most recent common ancestor of less than 200kya for chacma baboons in Zambia and Gorongosa, with both lineages sharing a node with yellow baboons from Tanzania less than 1 Mya. Genomic analyses indicate introgression in Central Mozambique and Zambia chacmas likely originated from populations closer to eastern rather than western Tanzanian yellow baboons.DiscussionOur findings reveal yellow baboon introgression in Central Mozambique chacmas, confirming this being a region hosting baboons with complex ancestry composition. Broader genomic surveys across Mozambique are necessary to uncover the population structure and evolutionary history of chacmas in this area, as well as the role of this region as a biodiversity crossroads for primates
"Trans-Channel melodrama: Frédérick Lemaître e Robert Macaire da Parigi a Londra"
No full textPlacing its focus on the interrelations between the theatrical worlds of London and Paris, this essay examines the effects and implications of the arrival of a French actor (and a star, moreover) on the mid-nineteenth-century London stage. In particular, it examines the moment when the sensational Parisian actor Frédérick Lemaître arrived there in early 1835, and caused a sensation in a theatrical dimension that was already hugely sensitized – and not always positively – to foreign presences and, especially foreign encroachments.
At the beginning of 1835 Lemaître arrived in London with his phenomenal ‘Robert Macaire’ material and its captivating brand of melodramatic, but also ironic, criminality. The arrival of this phenomenon, this essay contends, makes 1835 a significant test year in the development of the trans-Channel stage, a ‘hot chronology’ in which questions and issues acquire visibility and gain traction in major ways
Labeled Bovine Serum Albumin as a Fluorescent Biosensor to Monitor the Stability of Lipid-Based Formulations
No full textIn the pharmaceutical field, lipid-based nanoparticles are extensively used for drug or vaccine delivery, particularly for treating respiratory disorders. However, their physico-chemical instability, particularly associated with lipid degradation through hydrolysis or oxidation, can affect their encapsulation properties. To monitor the stability of lipid-based formulations over time, we prepared acrylodan-labeled bovine serum albumin (here called albuminodan), and showed it is a fluorescent biosensor capable of concomitantly detect phospholipids as well as their degradation products, i.e., fatty acids and lysophospholipids. We demonstrated that this tool can be used to follow the distribution of lipids in an aqueous phase and hence could be suitable to characterize the hydrolysis of phospholipids in a lipid-based formulation to monitor the stability of nanoparticles
From archival research to the digitization of existing architectural heritage: methods and processes compared
No full textThe study presented aims to experiment with the various possible applications of 3D modeling, both parametric and non-parametric, using historical and project archives as the primary source for acquiring documentation. The initial questions posed were: What are the peculiarities of the different types of approach? What are the outcomes in terms of content and reliability? Indeed, the different types of modeling lead to different considerations and conclusions, along with methodological approaches that require unequal specific attention.
The main objective is to explore the possibility of digitizing built heritage using 3D modeling, both parametric (according to the BIM process) and non-parametric, starting from the information, as mentioned, contained in the documents from historical archives, project documents, and all relevant archives. The research undertaken introduces some initial limitations, focusing particularly on the digitization of protected heritage and properties owned by public administrations.
The case studies addressed for the development of the theme are identified in two buildings by Ignazio Gardella and the historic Palazzo del Governatore in Parma. The selected outcomes were subjected, respectively, to non-parametric 3D modeling and parametric BIM modeling, highlighting the differences in modeling management processes, which are highly correlated with archival research. The aim is to understand how to effectively use both techniques, both to digitize architectural heritage and to optimize the conservation and management of its information
