1. Contribution to the knowledge of Gongolaria barbata (Sargassaceae, Fucales) from the Mediterranean : insights into infraspecific diversityAnnalisa Falace, Chiara Manfrin, Giovanni Furnari, Sara D’Ambros Burchio, Alberto Pallavicini, Emmanuelle Patricia Descourvières, Sara Kaleb, Ana Lokovšek, Daniele Grech, Giuseppina Alongi, 2024, original scientific article Abstract: Gongolaria barbata (Sargassaceae, Fucales) is a widespread species for which several infraspecific taxa have been described, indicating its polymorphism. This study contributes to the understanding of the molecular, nomenclatural, morphological and ecological aspects of G. barbata in the Mediterranean and sheds light on the infraspecific diversity and its implications for the taxonomy of this species. Molecular analyses were performed using sequencing of the mitochondrial cox1 gene on both haptophytic and pleustophytic forms from different sites in the Adriatic and Tyrrhenian Seas. Vegetative and reproductive morphology was studied on thalli samples from the Adriatic. Our results showed that there are different morphotypes within G. barbata populations related to specific environmental conditions, suggesting infraspecific variation. In contrast, molecular analyses showed no differences between samples, regardless of whether individuals are growing “attached” to a substrate or “unattached”. We also discussed the taxonomic status and nomenclatural issues related to certain infraspecific taxa previously proposed for G. barbata. In particular, the confusion surrounding Cystoseira aurantia is clarified.

2. Intentio Spiritus : the materialist, pneumatological origins of intention in AugustineAlberto Parisi, 2023, original scientific article Abstract: Intention is one of the catchwords of 20th-century Western philosophy. Positively or negatively, it takes a central role in numerous traditions, from phenomenology to analytic philosophy, and in none of them has it anything to do with air or breath. According to its widely accepted lineage, the concept of intention can be traced back to Medieval Scholastic philosophy, specifically to Augustine’s utilisation of this term. It is in Augustine’s intentio animi (the intention of the soul) – most critics argue – that intention first meant directing one’s attention towards something or a voluntary design or plan. In this paper, such a genealogy will not be proved wrong but rather complicated by taking seriously the (anti-)pneumatological context in which Augustine developed his concept of intention and, at the same time, those unheeded studies of his works that claim the origins of his use of intentio to lie in the Ancient Stoic concept of τόνος (tonos, tension or tone). A new study will show that intentio is what allows Augustine every time to prove the spirit to be immaterial, namely to not be a form of material air or breath. By transforming intentio into attentio (attention) first and voluntas (will) later, Augustine makes possible the realm of the immaterial spirit. Furthermore, however, this article also shows that his arguments seem to take for granted and reject an earlier, materialist pneumatological conception of intention, whose traces can be found in some of the works of the Roman Stoic Seneca, as well as in now-lost 4th century CE Christian heretical theories of the Holy Spirit.

3. Impact of comorbidity on the outcome in men with advanced prostate cancer treated with docetaxelAndrej Žist, Eitan Amir, Alberto Ocaña, Boštjan Šeruga, 2015, original scientific article Abstract: Men with metastatic castrate-resistant prostate cancer (mCRPC) may not receive docetaxel in everyday clinical practice due to comorbidities. Here we explore the impact of comorbidity on outcome in men with mCRPC treated with docetaxel in a population-based outcome study. Methods. Men with mCRPC treated with docetaxel at the Institute of Oncology Ljubljana between 2005 and 2012 were eligible. Comorbidity was assessed by the age-adjusted Charlson comorbidity index (aa-CCI) and adult comorbidity evaluation (ACE-27) index. Hospital admissions due to the toxicity and deaths during treatment with docetaxel were used as a measure of tolerability. Association between comorbidity and overall survival (OS) was tested using the Cox proportional hazards analysis. Results. Two hundred and eight men were treated with docetaxel. No, mild, moderate and severe comorbidity was present in 2%, 32%, 53% and 13% using aa-CCI and in 27%, 35%, 29% and 8% when assessed by ACE-27. A substantial dose reduction of docetaxel occurred more often in men with moderate or severe comorbidity as compared to those with no or mild comorbidity. At all comorbidity levels about one-third of men required hospitalization or died during treatment with docetaxel. In univariate analysis a higher level of comorbidity was not associated with worse OS (aa-CCI HR 0.99; [95% CI 0.87%1.13], p = 0.93; ACE-27: HR 0.96; [95% CI 0.79%1.17], p = 0.69).

4. A new approach towards a user-driven coastal climate service to enhance climate resilience in European citiesRoberta Paranunzio, Iulia Anton, Elisa Adirosi, Tasneem Ahmed, Luca Baldini, Carlo Brandini, Filippo Giannetti, Cécil J. W. Meulenberg, Alberto Ortolani, Francesco Pilla, 2024, original scientific article Abstract: Coastal climate services play a crucial role in developing customised climate information for diverse end-users and stakeholders. To build climate-resilient societies, decision-makers should be empowered through easy access to powerful tools that enable timely adaptation to future and ongoing hazards. For this reason, fit-for-purpose climate services are needed to conduct accurate historical characterisation and projections for interpretative studies on climate- and water-related risks at the local coastal scale. The EU-funded SCORE project (Smart Control of Climate Resilience in European Coastal Cities) utilises climate and marine services for the development of smart technologies that support nature-based solutions to address specific concerns, including rising sea levels, coastal erosion, and coastal flooding due to extreme weather events. As part of the SCORE project, decision-makers will be able to address climate change-related coastal effects in their own cities through novel participatory approaches (Coastal City Living Labs—CCLLs). As part of this framework, this work (i) discusses the main requirements for the identification of fit-for-purpose coastal climate services for local-scale impact studies in European coastal cities based on CCLL requests and prior knowledge and (ii) provides relevant parameters and features that fulfil the users’ needs.

5. Analog and digital image qualityAlberto Sardo, 2004, published professional conference contribution Abstract: Background. Lastly the X ray facilities are moving to a slow, but continuous process of digitalization. The dry laser printers allow hardcopy images with optimum resolution and contrast for all the modalities. In breast imaging, thedelay of digitalization depends to the high cost of digital systems and, attimes, to the doubts of the diagnostic accuracy of reading the breast digital images. Conclusions. The Screen film mammography (SFM) is the most efficient diagnostic modality to detect the breast cancer in early stage and with reasonable cost. The digital mammography (DM) with the independent capturing, displaying, processing, printing and archiving phases, makes possible an optimisation of the image guality for each, single phase, assuringa satisfactory diagnosis.

6. Deformable polyurethane joints and fibre grids for resilient seismic performance of reinforced concrete frames with orthoblock brick infillsTheodoros Rousakis, Alper Ilki, Arkadiusz Kwiecień, Alberto Viskovic, Matija Gams, Petra Triller, Bahman Ghiassi, Andrea Benedetti, Zoran Rakicevic, Camilla Colla, Omer Faruk Halici, BogusŁaw Zając, Łukasz Hojdys, Piotr Krajewski, Fabio Rizzo, Vachan Vanian, Anastasios Sapalidis, Efthimia Papadouli, Aleksandra Bogdanovic, 2020, original scientific article Abstract: The behaviour of reinforced concrete frames with masonry wall infills is influenced a lot by the stiffness and strength difference between the frame and the infill, causing early detrimental damage to the infill or to the critical concrete columns. The paper reports the results from shake table seismic tests on a full-scale reinforced concrete (RC) frame building with modified hollow clay block (orthoblock brick) infill walls, within INMASPOL SERA Horizon 2020 project. The building received innovative resilient protection using Polyurethane Flexible Joints (PUFJs) made of polyurethane resin (PU), applied at the frame-infill interface in different schemes. Further, PUs were used for bonding of glass fibre grids to the weak masonry substrate to form Fibre Reinforced Polyurethanes (FRPUs) as an emergency repair intervention. The test results showed enhancement in the in-plane and out-of-plane infill performance under seismic excitations. The results confirmed remarkable delay of significant infill damages at very high RC frame inter-story drifts as a consequence of the use of PUFJs. Further, the PUFJ protection enabled the resilient repair of the infill even after very high inter-story drift of the structure up to 3.7%. The applied glass FRPU system efficiently protected the damaged infills against collapse under out-of-plane excitation while they restored large part of their in-plane stiffness.

7. Effect of surface machining on the environmentally-assisted cracking of Alloy 182 and 316L stainless steel in light water reactor environments : results of the collaborative project MEACTOSMariia Zimina, Stefan Ritter, Bojan Zajec, Marc Vankeerberghen, Liberato Volpe, Anna Hojna, Rik-Wouter Bosch, Fabio Scenini, Zaiqing Que, Alberto Sáez-Maderuelo, P. Jill Meadows, Michael Grimm, Matthias Herbst, Andraž Legat, Agostino Maurotto, Radek Novotny, Karl-Heinz Seifert, 2023, original scientific article Abstract: The main objective of the EU-funded project mitigating environmentally-assisted cracking through optimisation of surface condition (MEACTOS) was to gain knowledge on the ability of different surface machining procedures to mitigate environmentally-assisted cracking (EAC) in typical light water reactor structural materials and environments. Surfaces of cold-worked (CW) type 316L austenitic stainless steel and nickel-based weld metal Alloy 182 flat tapered tensile specimens were machined using different processes. EAC initiation susceptibility of these specimens was evaluated using constant extension rate tensile (CERT) tests under simulated boiling water reactor (BWR) and pressurized water reactor (PWR) conditions and assessed using constant load experiments. More than a hundred tests were performed covering about 10 years of autoclave testing time. Only minor or no measurable improvements in EAC initiation susceptibility as a function of surface treatments (grinding or advanced machining) compared to the standard industrial face milling were demonstrated. In most cases, the stress thresholds for EAC initiation determined in constant load tests confirmed the trend obtained from CERT tests. This paper summarises the most important results and conclusions concerning the EAC initiation behaviour for the CW 316L and Alloy 182 under reducing PWR and oxidizing BWR conditions.

8. Production and characterization of lightweight aggregates from municipal solid waste incineration fly-ash through single- and double-step pelletization processAlberto Ferraro, Vilma Ducman, Francesco Colangelo, Lidija Korat, Danilo Spasiano, Ilenia Farina, 2023, original scientific article Abstract: The performance of a cold-bonding pelletization process was investigated for lightweight aggregates (LWAs) production from municipal solid waste incineration (MSWI) fly-ash (FA), by including multiple waste materials in the aggregate mixture. Before pelletization, FA was pre-treated by washing with water, which led to a reduction of chloride (66.79%) and sulphate (25.30%) content. This was further confirmed by XRF and XRD analyses, which showed a reduction of chloride elements and the content of chlorine crystalline phases. The pelletization process was carried out using both single- and double-step methods. For single-step pelletization, all the mixtures contained 80% FA, combined with various compositions of cement (5, 10, and 15%) and granulated blast furnace slag (GBFS) (5, 10, and 15%). For the double-step pelletization 30% of cement and 70% of marble sludge (MS) were added to each of the previous mixtures. The apparent density of all the aggregates varied between 1.60 and 1.87 g cm 3, suggesting their suitability to be classified as LWAs. Aggregates produced from double-step pelletization showed improved characteristics, with water absorption capacity and open porosity generally lower compared to the corresponding aggregates from the single-step pelletization. The best values of compressive (crushing) strength (almost 11 MPa) were observed for double-step pelletization aggregates with initial cement: GBFS mixture of 15%:5%. Results from leaching tests showed an overall significant release of chloride and sulphate. Nevertheless, leaching from double-step pelletization aggregates was reduced by 1.73- 4.02 times for chloride and 1.58-5.67 times for sulphate, further suggesting that better performances are achievable through the addition of an aggregate second layer.
