Urban heat islands intensify heat stress and degrade air quality in densely built areas, yet the physical processes governing near-surface thermal variability remain poorly quantified. This study applies the coupled MOLOCH and PALM model system 6.0 (PALM-4U) over Bologna (Italy) during a summer 2023 heatwave to resolve meter-scale atmospheric dynamics within the Urban Canopy Layer and Roughness Sublayer at 2 m horizontal resolution. The coupled configuration was validated against in situ meteorological observations and Landsat-8 LST data, showing improved agreement in air temperature and wind speed compared to standalone mesoscale simulations. Results reveal pronounced diurnal and vertical variability of wind speed, turbulent kinetic energy, and friction velocity, with maxima between two/three times the median building height (h_c). Distinct surface-dependent contrasts emerge: asphalt and roofs act as strong daytime heat sources (Bowen ratio β_asphalt ≈ 4.8) and nocturnal heat reservoirs at pedestrian level (z ≈ 0.07 h_c), while vegetation sustains daytime latent heat fluxes (β_vegetation ≈ 0.6÷0.8) and cooler surface and near-surface air (Temperature anomaly of surface ΔT_s ≈ −9 °C and air ΔT_air ≈ −0.3 °C). Thermal anomalies decay with height, vanishing above z ≈ 2.5 h_c due to turbulent mixing. These findings provide insight into fine-scale energy exchanges driving intra-urban thermal heterogeneity and support climate-resilient urban design. Full article

Human skeletal remains are a crucial source for understanding biocultural and evolutionary processes. Yet, their study and management are challenged by social, religious, and political factors, placing them in a ‘grey area’ within cultural heritage. Human skeletal collections often carry colonial legacies, raising ethical concerns and new challenges for research, curation, and public engagement in academic and museum institutions. In this context, digitization offers expanding opportunities for public exhibition and definition of human remains as part of our culture, while ensuring long-term preservation. Virtual approaches serve also as a useful tool to investigate human variability from evolutionary, bioarchaeological, and forensic perspectives. Moreover, digital access fosters interdisciplinary collaboration and research by enabling global scholarly engagement beyond physical limitations. Through the CHANGES project, we have initiated the digitization of the Documented Human Osteological Collections (DHOC) of the University of Bologna—one of Italy’s largest collections—making these resources available via the 3D data repository MorphoSource. This contribution provides updates on newly digitized material and reports on access requests received to date. We conclude by considering the emerging responsibilities of anthropologists in the use of virtual human skeletal collections, promoting best practices for the management of the anthropological digital twins.

Within the framework of an extensive conservation project involving multiple stained-glass windows of the Basilica of San Petronio in Bologna, Italy, this study reports the results of the diagnostic campaign on the rose window depicting Sant’Ambrogio between two angels holding the coats of arms of the Marsili family. The rose window is located in the homonymous chapel and, based on recent studies attributing the cartoon to the Bolognese painter Biagio Pupini, who was active in San Petronio from 1519, is dated to the early sixteenth century. No evidence was found regarding the workshop responsible for the production of the stained-glass window. The window showed no significant conservation issues, either in the glass elements or in the lead cames. However, the extensive degradation of the grisaille—likely caused by a low-quality mixture, improper firing, or aggressive cleaning—resulted in the loss of the original drawing. This study presents the results of non-invasive investigations on the glass tiles of the rose windows and the analyses of deposits present on their surfaces. Fiber Optic Spectroscopy (FOS) in transmittance, X Ray Fluorescence (XRF), and Hyper Spectral Imaging (HIS) in transmittance were used to investigate the glass composing the rose window. Fourier Transform Infrared Spectroscopy (FT-IR) was applied to study deposit samples collected from the external surface of the window. Additionally, only four glass samples, obtained from hidden areas or already detached fragments, were analyzed using Scanning Electron Microscope with Energy-Dispersive Spectroscopy (SEM-EDS). In addition, a photographic processing method is described, which enabled the recovery of the ghost image, the faint trace or imprint left by the grisaille on the glass during firing, allowing the conservators to faithfully reintegrate the original drawing.

The Bologna Process and the definition of the European Higher Education Area had a profound impact on higher education in Europe after 1999. But how exactly did this change the classroom, and how did research respond? This literature review aimed to identify changes in the literature on learning and teaching processes in higher education concerning organisation, pedagogical approaches, and curricular practices in the post-Bologna period (2010–2020) and to determine the main changes or transformations resulting from the Bologna Process. The research was conducted using the Scopus and Web of Science databases, and a set of 86 articles was defined with a PRISMA model. The procedure yielded three main categories concerning (i) global issues in teaching and learning processes, (ii) specifically active methodologies and (iii) the integration of ICT in higher education (HE) environments. Additionally, the research experimented with a fourth category concerning (iv) the cross-continental impact of the Bologna Process. The review indicates that the post-Bologna period was both important as a research theme and that these subjects underlining a student-centred education were impactful to the EEHA and even worldwide. However, most research also highlights the need to investigate and monitor the use of active and digital methodologies, carefully adapting to the diversity of students, universities, and cultures.

Since the 21st century, Russia has pursued the construction of world-class universities as a core reform goal in higher education, aiming to address the inadequacies of its post-Soviet higher education system in adapting to international competition. This study systematically examines the historical evolution, strategic framework, key characteristics, and practical challenges of Russia’s efforts over more than two decades. Russia’s practice has gone through three distinct stages: foundational construction (2003–2012), marked by joining the Bologna Process and establishing federal and national research universities; in-depth advancement (2012–2020), driven by initiatives such as the “5–100 Plan,” Global Education Program, and regional flagship universities; and adjustment and optimization (2020–present), represented by the “Priority-2030” plan. These efforts have formed a strategic framework centered on system construction, internationalization, balanced development, and operational support. Key characteristics of Russia’s practice include the integration of strategic stability and tactical flexibility, the complementarity of tiered and classified development, and the coordination of government leadership and university autonomy. However, challenges persist, such as underperformance in global rankings, insufficient funding, uneven resource distribution, and severe talent drain. Full article

This study investigates ground deformations in the southeastern Po Plain (northern Italy), focusing on the Bologna area—a densely populated region affected by natural and anthropogenic subsidence. Ground deformations in the area result from geological processes (e.g., sediment compaction and tectonic activity) and human activities (e.g., ground water production and underground gas storage—UGS). We apply a multidisciplinary approach integrating subsurface geology, ground water production, advanced differential interferometry synthetic aperture radar—DInSAR, gas storage data, and land use information to characterize and analyze the spatial and temporal variations in vertical ground deformations. Seasonal and trend decomposition using loess (STL) and cluster analysis techniques are applied to historical DInSAR vertical time series, targeting three representatives areas close to the city of Bologna. The main contribution of the study is the attempt to correlate the lateral extension of ground water bodies with seasonal ground deformations and water production data; the results are validated via knowledge of the geological characteristics of the uppermost part of the Po Plain area. Distinct seasonal patterns are identified and correlated with ground water production withdrawal and UGS operations. The results highlight the influence of superficial aquifer characteristics—particularly the geometry, lateral extent, and hydraulic properties of sedimentary bodies—on the ground movements behavior. This case study outlines an effective multidisciplinary approach for subsidence characterization providing critical insights for risk assessment and mitigation strategies, relevant for the future development of CO₂ and hydrogen storage in depleted reservoirs and saline aquifers.

A high intake of saturated fats and cholesterol from processed meats is associated with increased cardiovascular disease risk. This study aimed to develop a nutritionally enhanced Bologna-type sausage by partially replacing the beef content with a structured emulsion gel (EG) formulated from pine nut oil, inulin, carrageenan, and whey protein concentrate. The objective was to improve its lipid quality and functional performance while maintaining product integrity and consumer acceptability. Three sausage formulations were prepared: a control and two variants with 7% and 10% EG, which substituted for the beef content. The emulsion gel was characterized regarding its physical and thermal stability. Sausages were evaluated for their proximate composition, fatty acid profile, cholesterol content, pH, cooking yield, water-holding capacity, emulsion stability, instrumental texture, microstructure (via SEM), oxidative stability (TBARSs), and sensory attributes. Data were analyzed using a one-way and two-way ANOVA with Duncan’s test (p < 0.05). The EG’s inclusion significantly reduced the total and saturated fat and cholesterol, while increasing protein and unsaturated fatty acids. The 10% EG sample achieved a PUFA/SFA ratio of 1.00 and an over 80% reduction in atherogenic and thrombogenic indices. Functional improvements were observed in emulsion stability, cooking yield, and water retention. Textural and visual characteristics remained within acceptable sensory thresholds. SEM images showed more homogenous matrix structures in the EG samples. TBARS values increased slightly over 18 days of refrigeration but remained below rancidity thresholds. This period was considered a pilot-scale evaluation of oxidative trends. Sensory testing confirmed that product acceptability was not negatively affected. The partial substitution of beef content with pine nut oil-based emulsion gel offers a clean-label strategy to enhance the nutritional quality of Bologna-type sausages while preserving functional and sensory performance. This approach may support the development of health-conscious processed meat products aligned with consumer and regulatory demands. Full article

This study examines how climate citizens’ assemblies (CCAs) influence youth engagement, both in practice and in shaping perceptions of political “voice”, drawing on Albert O. Hirschman’s “Exit, Voice, and Loyalty” framework. Through qualitative analysis of 71 interviews, participatory workshops, and observational data across four cities—Barcelona, Bologna, Geneva, and Paris—it explores whether CCAs address youth climate activists’ demands, enable meaningful participation, and yield policy outcomes aligned with their claims. Findings reveal divergent perceptions: in Bologna, co-design with activists tended to foster trust, while Barcelona saw disillusionment due to unmet expectations. Geneva’s embedded deliberative processes strengthened institutional loyalty, whereas Paris faced skepticism as activists turned to civil disobedience. Overall, CCAs’ effectiveness hinges on inclusivity, follow-through, and communication; when perceived as tokenistic, they risk reinforcing disengagement (“exit”). The study underscores the need for embedded, responsive democratic innovations to sustain youth participation amid climate crises. Full article

This paper outlines a methodology for creating an educational and informative communication system for non-specialised audiences in order to preserve and pass on the heritage of ideas and practices adopted in the medieval political and administrative sphere. Through the combined use of digital technologies (such as GISs, 3D modelling and virtual tours), historical sources can potentially reveal how political and administrative aspects affected different areas within the medieval city, not just the main seats of power. Bologna, a prestigious medieval university metropolis, is chosen as a case study because of the remarkable wealth of documentation in its archives from the city’s political culture in the Middle Ages. Written historical sources, including documentary and narrative texts, are among the primary tools employed in the study of European medieval urban communities in general. Documentary sources help us understand and reconstruct the complexities of civic administration, urban policies and the economy, as well as how citizens experience them daily. The involvement of citizens in the political and administrative life of late medieval cities is explored through the management and digital processing of historical documentation. Digital humanities tools can facilitate this analysis, offering a perspective that sheds light on the formation of the pre-modern state. Although digital databases and repositories have significantly contributed to preserving and digitally archiving historical sources, these are often aimed exclusively at the academic level and remain underutilised as privileged didactic and educational tools for a broad audience.

Large-scale traffic simulations at a microscopic level can mimic the physical reality in great detail so that innovative transport services can be evaluated. However, the simulation times of such scenarios is currently too long to be practical. (1) Background: With the availability of Graphical Processing Units (GPUs), is it possible to exploit parallel computing to reduce the simulation times of large microscopic simulations, such that they can run on normal PCs at reasonable runtimes?; (2) Methods: ParSim, a microsimulator with a monolithic microsimulation kernel, has been developed for CUDA-compatible GPUs, with the aim to efficiently parallelize the simulation processes; particular care has been taken regarding the memory usage and thread synchronization, and visualization software has been optionally added; (3) Results: The parallelized simulations have been performed by a GPU with an average performance, a 24 h microsimulation scenario for Bologna with 1 million trips was completed in 40 s. The average speeds and waiting times are similar to the results from an established microsimulator (SUMO), but the execution time is up to 5000 times faster with respect to SUMO; the 28 million trips of the 24 h San Francisco Bay Area scenario was completed in 26 min. With cutting-edge GPUs, the simulation speed can possibly be further reduced by a factor of seven; (4) Conclusions: The parallelized simulator presented in this paper can perform large-scale microsimulations in a reasonable time on readily available and inexpensive computer hardware. This means microsimulations could now be used in new application fields such as activity-based demand generation, reinforced AI learning, traffic forecasting, or crisis response management.

The conservation of experimental building materials that were introduced during the 20th-century currently represents one of the main challenges in building restoration. Fair-faced concrete is especially affected by durability problems and requires careful assessment to implement effective conservation methods, even more so when the building has artistic and expressive value. In addition, the literature in this field is still limited and case studies are very rare. In this paper, the Partisan Ossuary Monument, a brutalist monument at the Certosa of Bologna, was studied and analysed in order to find the most effective restoration techniques, especially for its concretes, which have a particularly expressive texture. The aim was to combine both the preservation of the aesthetics and functional quality of the building with the use of existing technologies in this field. Firstly, archive research was carried out to discover the original building techniques and the materials used. The literature on the Monument was studied to unveil the expressive role given to the concretes’ surface finishing. Then, after an on-site investigation, all the materials used in the Monument and the degradation processes were analysed and mapped out. Significant samples of the Monument were manually collected whilst limiting invasiveness. Then, diagnostic tests were carried out to identify the causes of degradation and to comprehend the nature of certain superficial finishes. Several techniques were used, i.e., X-ray diffraction, optical microscopy, and FT-IR spectrometry. Finally, guidelines were drafted for possible future restoration, merging all the results from the previous phases of this study with compliance with heritage structures’ restoration requirements. Many technologies commonly used for the repair of concrete structures could not be applied to this Monument due to its features. Hence, new solutions were studied and proposed. The results obtained may contribute to an increased awareness of the need to restore 20th-century heritage buildings in order to limit degradation and partial reconstruction. Many concrete heritage buildings of this period suffer from the same problems, and this paper could offer an important starting point for future research. Full article

Background: Expanded Newborn Screening (ENS) allows the early identification of many inherited metabolic diseases (IMDs) for which timely treatment can modify the natural history. For most IMDs, diagnosis by ENS is pre-clinical. However, clinical symptoms may emerge for certain conditions before screening results become available. Methods: We describe six cases of patients with early-onset IMDs born between 2013 and 2023, who were admitted or transferred to Sant’Orsola University Hospital in Bologna (Italy). Results: Over the study period, 379,013 newborns underwent ENS in the Italian region of Emilia-Romagna. Excluding cases of congenital hypothyroidism, pre-clinical diagnoses from ENS were 410. In addition, six cases of IMD presented with early-onset clinical symptomatology, an antecedent to the outcome of newborn screening (incidence over 11 years of 1.58 cases per 100,000 infants). Among these patients, three were diagnosed with Urea Cycle Disorders (UCDs)—two with Citrullinemia type I (CIT1) and one with Argininosuccinic Acidemia (ASA); two were diagnosed with Methylmalonic Acidemia (MMA); and one was found to have Medium-Chain Acyl-CoA Dehydrogenase Deficiency (MCADD). Conclusions: Our 11-year experience with ENS has shown that clinical onset can occur between the second and fourth day of life, though rare. Even if dried blood spot (DBS) collection was performed 24–48 h after birth, the time required for sample transportation and processing would still delay result availability, making early intervention unlikely. Therefore, our experience supports performing ENS at 48–72 h, as currently implemented in Italy, while also highlighting the advantages and limitations of earlier screening. Full article

Claim management is a critical process for insurance companies, requiring fairness, transparency, and efficiency to maintain policyholder trust and minimize financial impact. In our previous work, we introduced Insoore AI, an insurtech solution leveraging deep learning-based computer vision to automate car damage recognition and localization from user-provided pictures. While this approach demonstrated the potential of AI in claims management, it faced limitations in terms of performance and computational efficiency due to resource constraints. In this study, we present an improved version of Insoore AI, enabled by the High-Performance Computing (HPC) resources offered by the Booster module of LEONARDO HPC system located at the CINECA datacenter in Bologna, Italy. By leveraging the advanced computational capabilities of the above-mentioned HPC infrastructure, we trained larger and more complex deep learning models, processed higher-resolution images, and significantly reduced training and inference times. Our results show marked performance improvements in terms of damage detection, paving the way for more efficient, more effective and scalable claims management solutions. This work underscores the transformative potential of HPC resources in advancing AI-driven innovations in the insurance sector and is to be regarded as an improvement on the contribution of our previous work, enabled by relying on the DiffusionDet architecture and on a Swin Transformer backbone to solve the problem of automatic car damage detection and classification.

This study explores the curriculum of Nursing Bachelor’s degrees across 15 European countries, aiming to describe nursing course curricula and admission requirements and to identify differences and similarities in the implementation of the Bologna Process. The research employs a qualitative and documentary methodology, analyzing curricula from selected higher education institutions involved in the Erasmus+ “Innovative Skills for Nurses” project. The findings reveal variations in the duration of training, with some countries adopting 3-year (180 ECTS) programs, while others require 4-year (240 ECTS) programs. Furthermore, discrepancies were found in the balance between theoretical and clinical education, as well as the availability of optional subjects. Countries with longer training programs tend to offer more consolidated practices and greater alignment with Bologna’s principles, fostering better professional outcomes. The study highlights the challenges posed by non-standardized training durations and their impact on mobility and employability of nursing professionals. These findings may inform future discussions on harmonizing nursing education across Europe to ensure consistency in quality and professional competencies. Full article

Introduction: The ongoing process of global warming, driven by the escalating concentration of greenhouse gases generated by human activities, especially in urban areas, significantly impacts public health. Local authorities play an important role in health promotion and disease prevention, and some aim to achieve net-zero greenhouse gas emissions. There is a consistent action underway to reach this goal, hence the need for mapping and implementing effective strategies and regulations. Materials and Methods: This study includes the analysis of policy guidelines adopted by the city of Bologna, consulted in March and April 2024. Bologna is one of the 100 cities committed to achieving climate neutrality by 2030, 20 years ahead of the EU target. To identify the strategies adopted to mitigate climate change, the following methodology was used: (i) the systematic mapping of sources and spatial planning documents; (ii) the extrapolation of goals, measures, and target indicators; and (iii) the development of an overall matrix. Results: The main findings of the study and their connection to public health pertain to the identification of key macro-areas contributing to the reduction of greenhouse gas emissions, while reducing the impact of climate change on health: (1) built environment and renewable energy sources, (2) transport and mobility, (3) energy, (4) green areas and land use, and (5) citizen support. Within these five macro-areas, 14 goals have been identified, to which a total of 36 measures correspond, and, finally, a target indicator is determined, mainly with respect to the reduction of tons of CO₂ equivalent per year. Conclusions: In order to protect public health, it is evident that buildings and urban activities should not produce carbon emissions throughout their lifecycle. This paper presents a method to evaluate municipal policies regarding dual-impact solutions that address both environmental protection through sustainability strategies and public health, in compliance with the Health in All Policies (HiAP) approach.
