Italy is a high seismic risk country. Since 1900 more than 30 earthquakes with magnitude greater than Mw=5.8 occurred, and the last one is the Central Italy seismic sequence. It heavily hit the regions of Marche, Umbria, and Abruzzo causing many deaths, injuries and extensive damages on the cultural heritage. This paper analyses the church of San Francesco in Amadola, located in the Marche region that has been considered condemned for the severe damages reported after these earthquakes. The church is globally analyzed by the application of nonlinear static analysis on a Finite Element Model where the nonlinearity of masonry is taking into account with a proper constitutive law. The study wants to prove how global analysis combined by the local analysis can reproduce the behavior of this structure during a quake, showing that it can repeat the real damages produced by earthquakes. © 2019 International Conference on Metrology for Archaeology and Cultural Heritage.

Maintaining indoor thermal comfort is crucial for the health and productivity of building occupants. Building envelope plays a major role in influencing the impact of outdoor climate and controlling the indoor thermal conditions. In this paper, comparative analysis of indoor comfortable temperature for four different types of building-integrated photovoltaic/thermal (BIPV/T) building models in a range of climate zones in Australia was conducted using TRNSYS simulation tool. In terms of system operational mode, the four types of BIPV/T building facade systems include a building-integrated photovoltaic single-skin facade (SSF), non-ventilated BIPV/T double-skin facade (BIPV/T-DSF), naturally ventilated BIPV/T-DSF and fan-assisted BIPV/T-DSF. In addition to the operational modes of the facade systems, two types of semi-transparent PV glazing with different visible light transmittance (VLT) were respectively applied to the models as external window glazing. The numerical results showed that the naturally ventilated BIPV/T-DSF with lower VLT (27%) PV glazing maintained a relatively better indoor temperature for the hot climatic conditions compared to the other operational modes, while the non-ventilated BIPV/T-DSF with higher VLT PV glazing (37.5%) offered more comfortable indoor temperature (i.e. 20 to 26 °C for office hours) for the cold climates in Australia. On the other hand, the naturally ventilated BIPV/T-DSF could basically maintain comfortable indoor temperatures from 22 to 27 °C during office hours without mechanical systems for the peak summer times for cool temperate climates in Australia. Moreover, it was found that the thermal insulation effect of semi-transparent PV glazing hardly affected indoor operative temperature in the ventilated modes of the BIPV/T-DSF. According to the sensitivity analysis, the change of U-value of internal window of the DSF would significantly lead to the change of indoor thermal comfort in both ventilated operational modes, but v

This research work is devoted to using plastic wastes, the most significant cause of modern pollution and global warming, as components of plaster mortars to find a new technique for the seismic retrofitting of existing masonry buildings. Therefore, the research aims to increase the sustainability of constructions through plastic trashes recyclability. By changing the percentage of two different types of plastic fibres (Plexiglass and PET) from 0,5% to 2% within a green mortar mixture composed of sand, lime, and water, the mechanical and physical properties of the reinforced mortars have been investigated through laboratory tests. The experimental activities show positive results in terms of strength and deformation capacities of the used fibre-reinforced mortar, which could be exploited to increase the seismic performance of existing masonry walls subjected to seismic loads.

作者： Ehsanolah Assareh Aminhossein Jahanbin Nima Izadyar Mohammad Barati Neha Agarwal Built Environment and Engineering Program College of Sport Health and Engineering (CoSHE) Victoria University Melbourne VIC 3011 Australia School of Chemical Engineering Yeungnam University Gyeongsan 38541 South Korea Department of Architecture Construction and Design Polytechnic University of Bari 70126 Bari Italy Institute for Sustainable Industries and Liveable Cities Victoria University Melbourne VIC 3011 Australia Department of Mechanical Engineering Arvandan Non-profit Higher Education Institute Khorramshahr Iran

This study investigates the potential of leveraging solar energy to establish an integrated multi-energy production system to supply heating, cooling, and electricity for passenger trains. The proposed tri-generation system combines photovoltaic-thermal (PVT) panels, an organic Rankine cycle (ORC), an absorption chiller, and a water heater unit. The interactions between system components are examined through an exergoeconomic model developed in EES software, supported by a detailed parametric analysis. A two-step multi-objective optimization framework is implemented, integrating response surface methodology (RSM) with an artificial neural network (ANN) to improve optimization accuracy. In this framework, five decision variables and two objective functions—exergy efficiency and system cost rate—are optimized. Economic analysis reveals that the ORC unit and PVT panels incur the highest cost rates, while exergy analysis indicates that the PVT panels, absorption chillers, and evaporators experience the most significant exergy destruction. The optimal system achieves an exergy efficiency of 10.87% and a cost rate of 1.491 $/h. The second optimization stage using the ANN method based on 100 RSM-optimized points, results in further refinement in both exergy efficiency and cost rate. A real-world case study evaluates the feasibility of implementing the proposed system on a modern passenger train along a route with high solar energy potential, analyzing its performance during a 17-hour journey across five stations and over four seasons under varying weather conditions. The findings contribute to the development of low-carbon rail transport solutions, highlighting the need for future research on energy storage, system scalability, and real-time performance optimization.

Rhenium disulfide (ReS2) belongs to group-VII transition metal dichalcogenide (TMDs) with attractive properties such as exceptionally high refractive index and significant oscillator strength, large in-plane birefringence, and good chemical stability. Unlike most other TMDs, the peculiar optical properties of ReS2 persist from bulk to the monolayer, making this material potentially suitable for applications in optical devices. In this work, we demonstrate with unprecedented clarity the strong coupling between cavity modes and excited states, which results in a strong polariton interaction, showing the interest of such materials as a solid-state counterpart of Rydberg atomic systems. Moreover, we definitively clarify the nature of important spectral features, shedding light on some controversial aspects or incomplete interpretations and demonstrating that their origin is due to the interesting combination of the very high refractive index and the large oscillator strength expressed by these TMDs.

Valuable metal elements (VMEs) are critical components underpinning modern society, yet their extraction generates VME-rich slag and tailings at volumes dozens of times greater than the recovered products. Conventional stockpiling and cement-based landfill strategies pose dual risks: persistent leaching of VMEs into aquatic systems and substantial CO₂ emissions, aggravating global mineral-water resource conflicts. To address this, we developed an electrodynamics-assisted alkali chemistry (EAC) process that synchronizes tailings stabilization with VME recovery. The EAC method leverages electrokinetic migration to enrich VMEs at the cathode during alkali-activated slurry hardening, enabling efficient temporary retention for subsequent metallurgical extraction, while the anode region undergoes rapid consolidation for mine shaft rehabilitation. Validated through lab experiments and scaled field trials, EAC demonstrated a compressive strength enhancement of two orders of magnitude in treated tailings compared to conventional approaches, alongside a 70 % increase in VME recovery efficiency and an 80 % reduction in CO₂ emissions. This study establishes EAC as a transformative, green, and low-carbon technology that concurrently addresses mine restoration, resource circularity, and emission mitigation. By redefining tailings management from waste disposal to value recovery, EAC provides a paradigm shift toward sustainable mining practices, offering critical insights for resolving global resource sustainability challenges.

The paper assesses the environmental risks of the impact of sewer networks on the whole of the environment components such as atmospheric air, soils and water environment as a prerequisite for sustainable urban development. An algorithmic support for the analysis of environmental risks that occur during operation or in case of emergencies in sewer networks has been developed. The risk assessment was performed for 11 sewer shafts in Kharkiv based on field measurements: for atmospheric air, according to four environmentally hazardous gaseous substances generated in sewer networks; for water environment and soils, according to 12 indicators and pollutants. A high level of environmental risk to atmospheric air has been found in three shafts. Environmental risks to the water environment and soils are imposed by phosphates and synthetic surfactants.s

This paper proposes a concise concept for quantifying the shear/torsional stiffness of the laminated glass beams experimentally by introducing the Equivalent-Sectional Shear Modulus (ESSM), that is directly measured from the torque and sectional-rotation correlation with the torsion test and tailor-made photogrammetry technique. The advantage of this method is originated from the concept of measuring the overall rotation to torque response of a laminated glass beam altogether rather than the component individually. This eliminates the uncertainties of analytical approximations that are commonly adopted by most existing methods in which the composite shear/torsion stiffness is derived from its component mechanical properties. The photogrammetry technique increased the accuracy of the sectional rotation measurement by acquiring dense displacement sample points on the glass beam simultaneously. The accuracy of the photogrammetry setup and efficacy of the test design were proven by a micrometre and a monolithic glass beam test. One sample each for the polyvinyl butyral (PVB) and SentryGlas Plus (SGP) laminated glass beams were tested multiple times non-destructively to determine the ESSM. The result of the SGP laminated glass beam showed a closer agreement with the previous studies, however the result of the PVB laminated glass beam exhibited a larger difference from the previous studies. It also suggested that mechanical properties of the interlayer played an important role in the composite behaviour of the laminated glass beam. The experimental outcomes have demonstrated the proposed method is an accurate and effective technique for measuring the ESSM of laminated glass beams. © 2021, CC BY.

The active digitalization of the healthcare system has given impetus to the emergence of a new type of enterprise—high-tech medical organizations (HMO). Their main distinguishing feature is the use of innovative high-tech medical equipment. However, the high cost of this equipment has become a factor slowing down the development of such organizations. This paper considers the life-cycle contract (LCC) as a special form of interaction between stakeholders and investments throughout the life cycles of equipment. Moreover, to provide technological support, continuous acquisition and life-cycle support (CALS) technologies, which are based on the same principles of working with the life cycle as LCC, are proposed. This question turned out to be a significant research gap, which was not sufficiently reflected in the available world studies. Thus, the aim of the current study is to describe the features of the use of LCC for HMO using CALS technologies and the impact of the life cycle of high-tech medical equipment on LCC, as well as to present the innovative component of the proposed model. Based on the analysis of the literature and the best world practices, the authors propose a visualization of the interaction of all stakeholders within the LCC for HMO. Such a decision is extremely relevant for developing organizations, public authorities and investors around the world. © 2022 by the authors.

Gauge field theory provides the mathematical and conceptual framework to describe and understand topological singularities such as Weyl points and magnetic monopoles. While singularities associated with vector electromagnetic gauge fields have been well studied, those of higher-form tensor gauge fields, like the four-dimensional (4D) tensor monopoles predicted by string theory, have remained largely theoretical or limited to experimental demonstration in pure synthetic dimensions, thereby not allowing investigations of the associated boundary effects. Here, we present a 4D system with tensor monopoles using engineered acoustic metamaterials. Our momentum space combines three real momentum dimensions and a geometric parameter as the fourth. By varying this fourth momentum, we experimentally reveal two distinct topological surface states in 3D subsystems: Fermi-arc surface states in a gapless subsystem and Dirac-cone surface states in a gapped subsystem. Our work introduces a novel platform for exploring new topological structures associated with tensor gauge field and topological phenomena in higher dimensions.
