Virtual learning environments (VLEs) in physical geography education offer significant potential to aid students in acquiring the essential skills for the environmental interpretation of glacial and periglacial environments for geoscience careers. Simulated real-world field experiences aim to help the student evaluate landscapes for natural hazards, assess their intensity, and translate and communicate this information to various stakeholders in human systems. The TREE-PG framework and VRUI model provide a philosophical and practical foundation for VLE architects, aiming to cultivate students’ knowledge, skills, and identity as geoscientists, specifically as physical geographers and geomorphologists. These frameworks emphasize the importance of translating scientific knowledge from physical features into engaging, accessible online lessons, exemplified by landscapes like those in Glacier National Park, Montana. Open-source software and open educational resources (OERs) can broaden access and incorporate diverse perspectives in these experiences, which are necessary to address the impacts of vulnerable communities to global deglaciation. Designing and creating virtual proxies of field-based education may help address issues associated with inclusion and belonging within geoscience disciplines to connect all students with dynamic physical environments beyond the classroom. Ethical AI approaches and discipline-specific repositories are needed to ensure high-quality, contextually accurate VLEs. AI’s tendency to produce output necessitates using domain-specific guardrails to maintain relevance and precision in virtual educational content.
How Were European GPs/FPs Involved in the COVID-19 Vaccination Campaign? A European Questionnaire Study about the Experiences of the Vaccinations in 2021
Authors: Rurik Imre , Torzsa Péter
Published: September 2024

Background: The SARS-CoV-2 pandemic has become the greatest public health challenge worldwide. Soon after the appearance of the virus in 2019, intensive efforts to develop vaccines were initiated, and by late 2020, delivery of vaccines for the targeted population as a campaign had started. Aim: Collect information from European Union countries regarding how and to what extent were family physicians (FPs)/general practitioners (GPs) involved in the vaccination campaigns in 2021 and how these were organized at the national level. Method: A short questionnaire was distributed through the secretariats of WONCA (World Organization of Family Doctors) Europe and the European Forum for Primary Care (EFPC). Results: In most of the countries, participation of FPs/GPs was compulsory. The vaccination was usually centrally organized by governmental authorities. In the beginning, registration (web-based) of patients was required, mainly at the national level. By the middle of 2021, vaccination on a walk-in basis became available in almost every country for the first immunization as well as for the booster injections. The remunerations of GPs/FPs differed; in some countries, no extra payments were offered. The Pfizer vaccine was used in all countries, while in nine countries, non-European Medicines Agency (EMA)-approved vaccines were also given in primary care settings and at vaccination centers. In some countries, professional homepages helped the GPs. The involvement of primary health care (PHC) providers did not correlate to the vaccination coverage of the entire population of the respective countries. It was the highest in the more developed countries with higher living standards, where participation of GPs was voluntary and appropriate financial incentives were offered to them. Conclusions: The vaccination campaign was a professional and logistic challenge and an excellent performance of PCH providers. Experiences gained could be used in the future to manage similar pandemic challenges.
Lacquers of the Amazon: Cuias, Cumatê and Colours by Indigenous Women in Grão-Pará in the 18th Century
Authors: Martins Renata Maria de Almeida
Published: September 2024

The starting point of this proposal is a collection of decorated cuias, preserved in Portugal and produced by Indigenous women in Grão-Pará in the 18th century. The objects in question are an exemplary case of the global art history of the Amazonian communities. In order to investigate them, it is necessary to consider the procurement and ritual use of cuias (fruits of the cuieira tree-Crescentia cuyete), the sophisticated techniques used to produce a durable, glossy, black varnish from cumatê (or cumaté, cumati), a natural dark red pigment extracted from the skins of the cumatezeiro or axuazeiro tree (Myrcia atramentifera), as well as the incorporation of fauna and flora motifs from Asian or Asian-inspired textiles and embroidery, which circulated worldwide. Their history brings together the nature of the forest, the myths of creation, and the knowledge and practices of Indigenous and riverine women, mainly from the lower Amazon. Studying these objects produced by Indigenous female painters in a colonial context of appropriation, in addition to contributing to their knowledge, can stimulate dialogues on the knowledge of the Brazilian Amazon rainforest with other locations in America, sharing their ancestry and resistance.

The eating behavior (EB) and habits developed during adolescence tend to persist into adulthood, with parents and caregivers playing a significant role in shaping their children’s food choices. The home environment is a crucial setting for developing eating behavior during adolescence. This study aimed to explore the influence of the home food environment (HFE) and its correlates on EB, family meals (FMs), and academic achievement among adolescents in schools in the United Arab Emirates (UAE). A cross-sectional study was conducted with 304 school-aged adolescents from the UAE. The questionnaire included sociodemographic data, dietary habits, information related to the HFE (food availability and accessibility), physical activity, sleep patterns, and academic achievement. Several questionnaire items were combined to create an HFE score. These questions included the frequency of weekly family meals, meal preparation practices, and accessibility to healthy and unhealthy food products and snacks at home. The HFE score was dichotomized into favorable and unfavorable HFE scores. Similarly, EB and FM scores were generated by combining responses to various related questions. The participants’ weights and heights were measured. The findings reported that more than half (55%) of the adolescents were either overweight or obese. The majority of the participants had favorable HFE (57.2%), EB (69.1%), and FM scores (58.2%). The significant correlates to the HFE were as follows: male participants whose parents attended college (OR: 0.31; 95% CI: 0.15–0.62; p < 0.001), high academic achievers (OR: 1.98; 95% CI: 1.02–3.82; p = 0.043), and those who were physically active (OR: 1.80; 95% CI: 1.14-2.85; p = 0.012), were more likely to have favorable HFE. Moreover, the HFE score showed a highly significant positive correlation with the EB score (r = 0.573, p < 0.001) and the FM score (r = 0.384, p < 0.001). These results underscore the critical role of a healthy HFE in shaping healthy positive eating behaviors and food choices among adolescents. They provide a foundation for developing effective, evidence-based policies that can impact the health and academic success of adolescents in the UAE.
Exploring the Impact of Stigma on Health and Wellbeing: Insights from Mothers with Lived Experience Accessing Recovery Services
Authors: Lochhead Lydia , Addison Michelle , Cavener John , Scott Steph , McGovern William
Published: September 2024

Stigmatisation is the process by which an individual is devalued based on their attributes, characteristics, and/or behaviour, with this often leading to prejudice, social and health-related harms, active discrimination, and microaggressions. The aim of this paper is to show how social harms can occur and how stigma is damaging to the health and wellbeing of a person in recovery. To do so, we focus on the harms that arise from the internalisation of labels that mothers who use drugs encounter in a treatment and recovery setting whilst in active recovery, and how this stigmatisation can manifest negative self-beliefs. Qualitative data was used from two semi-structured focus groups involving females with lived experience of substance use (n = 13). A reflexive thematic analysis approach was used to analyse the interview transcripts, and three themes were identified: (1) the enduring nature of stigma; (2) gender disparity and the need for mothers- and women-only spaces; and (3) stigma as a barrier to services and wellbeing. Findings revealed the enduring nature of stigma amongst mothers who were in active recovery, with women feeling judged more harshly than men and experiencing pressure to live up to a “good mother” ideal whilst in recovery. This paper demonstrates that mothers in recovery are still stigmatised and, as a consequence, approach services with increased sensitivity, with stigma often resulting in disengagement or reluctance to access healthcare settings. We conclude that staff in health, social, and primary care settings need to develop a strong therapeutic alliance with mothers in recovery and promote anti-stigma approaches in their practice, in order to mitigate stigma and reduce harms to health and wellbeing.

Study on Joint Model Simplification for Finite Element Analysis of Bamboo/Wood-Oriented Strand Board Furniture
Authors: Zhang Kaiting , Zhang Jun , Guo Yong , Chen Yuxia
Published: September 2024

Board furniture’s performance and scientific design are making it popular. Research on simplifying furniture joints reduces design cycles and costs and improves structural safety. In this article, using a cantilever beam to calculate deflection theoretically simplifies the L-shaped component model and yields a joint elastic modulus formula. Finite element analysis (FEA) confirms the effectiveness of this simplified model by comparing its results with experimental data. In simplified components, the joint elastic modulus increases with length (l2) and stabilizes at l2/b ≥ 6 (b is the board’s thickness). The variation pattern of the joint elastic modulus equals that of the stiffness, proving its usefulness in assessing component deformation resistance. Furthermore, the component strength and stiffness are also affected by the screw spacing and connector type. In particular, the connectors type affects bamboo-oriented strand board (BOSB) component performance more than wood-oriented strand board (WOSB). Compared to WOSB, BOSB components have superior strength and stiffness and are more stable. The recommended screw spacing for L-shaped components is 48 mm. BOSB components fixed with two-in-one and metal nuts utilizing threads embedded in the board have better strength and stiffness, while for WOSB components, nylon nuts, and wooden dowel pins are more appropriate for securing.

Surface-Enhanced Raman Spectroscopy (SERS) is a powerful, non-destructive technique for enhancing molecular spectra, first discovered in 1974. This study investigates the enhancement of Raman signals from single- and few-layer molybdenum disulfide (MoS2) when interacting with silver nanoparticles. We synthesized a MoS2 membrane primarily consisting of monolayers and bilayers through a wet chemical vapor deposition method using metal salts. The silver nanoparticles were either directly grown on the MoS2 membrane or placed beneath it. Raman measurements revealed a significant increase in signal intensity from the MoS2 membrane on the silver nanoparticles, attributed to localized surface plasmon resonances that facilitate SERS. Our results indicate that dichalcogenide/plasmonic systems have promising applications in the semiconductor industry.

Published: September 2024

To reduce land use and avoid further pollution, incineration for power generation has become the main method for municipal solid waste treatment. This research focused on the potential for transforming Municipal Solid Waste Incineration Bottom Ash (MSWIBA) into a finely ground powder. The impact of the powder’s fineness and the amount of water used on its effectiveness was analyzed using a method called grey theory. MSWIBA was used as a partial substitute for cement in making MSWIBA foam concrete and lightweight wall panels. By modifying the fineness and water utilization of the recycled micro-powder, its maximum activity index can be increased to 90.1. This study determined the influence of factors including apparent dry density, water–cement ratio, foaming agent dilution ratio, and admixture dosage on the strength of the recycled foam concrete, and established the optimal mix ratio. This study employed a combination of physical experiments and numerical simulations to elucidate the impact of panel material, core layer thickness, and layer sequence on sound insulation performance. The simulation results were in close agreement with the experimental findings.
Effect of Calcium on the Setting Time and Mechanical Property of a Red Mud–Blast Furnace Slag-Based Geopolymer

Published: September 2024

This study aims to compare the effects of three calcium compounds on the workability, setting time and mechanical properties of red mud (RM)–blast furnace slag (BFS)-based geopolymers. The crystalline phase, hydration process and microstructure of RM-BFS-based geopolymers were characterized by X-ray diffraction (XRD), heat evolution, X-ray photoelectron spectroscopy (XPS), and scanning electron microscope (SEM) tests. The results showed that an appropriate amount of calcium compounds can improve the flowability and compressive strength of the geopolymers, but the excessiveness causes a decrease in strength due to rapid hardening. Other than calcium carbonate, both calcium oxide and calcium chloride played important roles in accelerating the setting times of RM-BFS-based geopolymers. The acceleration in the setting times of geopolymers could be attributed to the calcium hydroxide produced by the dissolution of the calcium compounds, which also provides nucleation sites for the geopolymerization reaction. This study gives new insights into the effect of calcium on the setting times and mechanical properties of geopolymers in the geopolymerization process.
Conceptual Piezoelectric-Based Energy Harvester from In Vivo Heartbeats’ Cyclic Kinetic Motion for Leadless Intracardiac Pacemakers
Authors: Khazaee Majid , Riahi Sam , Rezania Alireza
Published: September 2024

This paper studies the development of piezoelectric energy harvesting for self-powered leadless intracardiac pacemakers. The energy harvester fit inside the battery compartment, assuming that the energy harvester would replace the battery with a smaller rechargeable battery capacity. The power output analysis was derived from the three-dimensional finite element analysis and in vivo heart measurements. A Doppler laser at the anterior basal in the right ventricle directly measured the heart’s kinetic motion. Piezoceramics in the cantilevered configuration were studied. The heart motion was periodic but not harmonic and shock-based. This study found that energy can be harvested by applying periodic bio-movements (cardiac motion). The results also showed that the energy harvester can generate 1.1 V voltage. The effect of various geometrical parameters on power generation was studied. This approach offers potential for self-powered implantable medical devices, with the harvested energy used to power devices such as pacemakers.
Lipoteichoic Acid from Heyndrickxia coagulans HOM5301 Modulates the Immune Response of RAW 264.7 Macrophages

Published: September 2024

Heyndrickxia coagulans (formerly Bacillus coagulans) has been increasingly utilized as an immunomodulatory probiotics. Oral administration of H. coagulans HOM5301 significantly boosted both innate and adaptive immunity in mice, particularly by increasing the phagocytic capacity of monocytes/macrophages. Lipoteichoic acid (LTA), a major microbe-associated molecular pattern (MAMP) in Gram-positive bacteria, exhibits differential immunomodulatory effects due to its structural heterogeneity. We extracted, purified, and characterized LTA from H. coagulans HOM5301. The results showed that HOM5301 LTA consists of a glycerophosphate backbone. Its molecular weight is in the range of 10–16 kDa. HOM5301 LTA induced greater productions of nitric oxide, TNFα, and IL-6 in RAW 264.7 macrophages compared to Staphylococcus aureus LTA. Comparative transcriptome and proteome analyses identified the differentially expressed genes and proteins triggered by HOM5301 LTA. KEGG analyses revealed that HOM5301 LTA transcriptionally and translationally activated macrophages through two immune-related pathways: cytokine–cytokine receptor interaction and phagosome formation. Protein–protein interaction network analysis indicated that the pro-inflammatory response elicited by HOM5301 LTA was TLR2-dependent, possibly requiring the coreceptor CD14, and is mediated via the MAPK and NF-kappaB pathways. Our results demonstrate that LTA is an important MAMP of H. coagulans HOM5301 that boosts immune responses, suggesting that HOM5301 LTA may be a promising immunoadjuvant.

As the relationship between the gut microbiome and allergies becomes better understood, targeted strategies to prevent and treat allergies through gut microbiome modulation are being increasingly developed. In the study presented herein, we screened various probiotics for their ability to inhibit mast cell degranulation and identified Lactiplatibacillus plantarum HD02 and MD159 as effective candidates. The two strains significantly attenuated vascular permeability induced by mast cell degranulation in a passive cutaneous anaphylaxis (PCA) model and, in the MC903-induced murine atopic dermatitis (AD) model, demonstrated comparable preventive effects against allergies, reducing blood levels of MCPT-1 (mast cell protease-1) and total IgE. In the house dust mite (HDM)-induced murine AD model, both L. plantarum HD02 and MD159 showed therapeutic effects, with L. plantarum HD02 demonstrating superior efficacy. Nevertheless, L. plantarum MD159 better suppressed transepidermal water loss (TEWL). Furthermore, L. plantarum HD02 and MD159 significantly increased the number of splenic Foxp3+ regulatory T cells, with L. plantarum MD159 having a more pronounced effect. However, only L. plantarum HD02 achieved a reduction in immune cells in the draining lymph nodes. Our findings highlight L. plantarum HD02 and MD159 as promising candidates for the prevention and treatment of allergies, demonstrating significant efficacy in suppressing mast cell degranulation, reducing the number of allergy biomarkers, and modulating immune responses in experimental models of AD. Their distinct mechanisms of action suggest potential complementary roles in addressing allergic diseases, underscoring their therapeutic promise in clinical applications.

Published: September 2024

Manihot esculenta (cassava) roots is a major food crop for its energy content. Leaves contain nutrients and demonstrate biological properties but remain undervalorized. In order to develop a bioguided optimization of cassava nutrition–health properties, we compared the phytochemistry and bioactive potential of cassava root flour extract (CF) with cassava flour extract enriched with 30% leaves powder (CFL). Cassava flour supplementation impact was explored on flour composition (starch, fiber, carotenoids, phenolic compounds), in vivo glycemic index, and bioactivity potential using macrophage cells. We assessed the impact of cassava flour supplementation on free radicals scavenging and cellular production of pro-inflammatory mediators. CFL showed higher levels of fiber, carotenoids, phenolic compounds, and lower glycemic index. Significantly higher bioactive properties (anti-inflammatory and antioxidant) were recorded, and inhibition of cytokines production has been demonstrated as a function of extract concentration. Overall, our results indicate that enrichment of cassava flour with leaves significantly enhances its nutrition–health and bioactive potential. This bioguided matrix recombination approach may be of interest to provide prophylactic and therapeutic dietary strategy to manage malnutrition and associated chronic non-communicable diseases characterized by low-grade inflammation and unbalanced redox status. It would also promote a more efficient use of available food resources.

Published: September 2024

In this work, we developed a smart drug delivery system composed of poly (ethylene glycol)-block-poly (ε-caprolactone) (PEG-PCL)-based polymersomes (Ps) loaded with doxorubicin (DOX) and vemurafenib (VEM). To enhance targeted delivery to malignant melanoma cells, these drug-loaded nanovesicles were conjugated to the oxalate transferrin variant (oxalate Tf) and incorporated into three-dimensional chitosan hydrogels. This innovative approach represents the first application of oxalate Tf for the precision delivery of drug-loaded polymersomes within a semi-solid dosage form based on chitosan hydrogels. These resulting semi-solids exhibited a sustained release profile for both encapsulated drugs. To evaluate their potency, we compared the cytotoxicity of native Tf-Ps with oxalate Tf-Ps. Notably, the oxalate Tf-Ps demonstrated a 3-fold decrease in cell viability against melanoma cells compared to normal cells and were 1.6-fold more potent than native Tf-Ps, indicating the greater potency of this nanoformulation. These findings suggest that dual-drug delivery using an oxalate-Tf-targeting ligand significantly enhances the drug delivery efficiency of Tf-conjugated nanovesicles and offers a promising strategy to overcome the challenge of multidrug resistance in melanoma therapy.

Published: September 2024

Periodontitis is a chronic inflammation caused by periodontopathogenic bacteria in the dental biofilm, and also involves the inflammatory-immune response of the host. Polymorphonuclear neutrophils (PMNs) play essential roles in bacterial clearance by multiple mechanisms, including the formation of neutrophil extracellular traps (NETs) that retain and destroy pathogens. During PD progression, the interaction between PMNs, NETs, and bacteria leads to an exaggerated immune response and a prolonged inflammatory state. As a lesion matures, PMNs accumulate in the periodontal tissues and die via NETosis, ultimately resulting in tissue injury. A better understanding of the role of NETs, the associated molecules, and the pathogenic pathways of NET formation in periodontitis, could provide markers of NETosis as reliable diagnostic and prognostic tools. Moreover, an assessment of NET biomarker levels in biofluids, particularly in saliva or gingival crevicular fluid, could be useful for monitoring periodontitis progression and treatment efficacy. Preventing excessive NET accumulation in periodontal tissues, by both controlling NETs’ formation and their appropriate removal, could be a key for further development of more efficient therapeutic approaches. In periodontal therapy, local drug delivery (LDD) systems are more targeted, enhancing the bioavailability of active pharmacological agents in the periodontal pocket and surrounding tissues for prolonged time to ensure an optimal therapeutic outcome.

Published: September 2024

Polymer additive manufacturing has advanced from prototyping to producing essential parts with improved precision and versatility. Despite challenges like surface finish and wear resistance, new materials and metallic reinforcements in polymers have expanded its applications, enabling stronger, more durable parts for demanding industries like aerospace and structural engineering. This research investigates the tribological behaviour of FFF surfaces by integrating copper and aluminium reinforcement particles into a PLA (polylactic acid) matrix. Pin-on-disc tests were conducted to evaluate friction coefficients and wear rates. Statistical analysis was performed to study the correlation of the main process variables. The results confirmed that reinforced materials offer interesting characteristics despite their complex use, with the roughness of the fabricated parts increasing by more than 300%. This leads to an increase in the coefficient of friction, which is related to the variation in the material’s mechanical properties, as the hardness increases by more than 75% for materials reinforced with Al. Despite this, their performance is more stable, and the volume of material lost due to wear is reduced by half. These results highlight the potential of reinforced polymers to improve the performance and durability of components manufactured through additive processes.
Fenugreek Galactomannan and Its Versatile Applications
Authors: Nalbantova Vanya , Benbassat Niko , Delattre Cédric
Published: September 2024

Fenugreek (Trigonella foenum-graecum L.) is an annual, dicotyledonous medicinal plant which belongs to the Leguminosae family, and its leaves and seeds are widely used and cultivated throughout the world. Their widespread utilization is attributed to the great variety of primary and secondary metabolites they contain, such as flavonoids, alkaloids, steroidal saponins, tannins, as well as carbohydrates, in particular galactomannan, which is the focus of the current study. The presence of an equal number of galactose and mannose residues (Gal/Man ratio of 1:1) prevents the formation of hydrogen bonds between the mannose ones. This determines the good solubility of fenugreek galactomannan in cold water, even at low concentrations. The water solubility would be significantly better than that of carob and even slightly higher than that of guar gum, precisely due to their structural characteristics, which contribute to their possible advantages. Moreover, it is a good alternative as an excipient for the development of pharmaceutical dosage forms, as well as in the preparation of food products, affecting not only their structure but also their shelf life. Furthermore, it has promising applications not only in the fields of medicine and pharmaceutics but also offers environmental benefits. All of the above-mentioned factors are of high interest and qualify fenugreek galactomannan as a versatile polysaccharide, which is the reason for summarizing its benefits in this review.

Published: September 2024

As a crucial reserve for natural gas, the safe operation of underground gas storage facilities is paramount for seasonal peak shaving and emergency supply security. Focusing on the Lei X gas storage facility in the Liaohe Basin of China, this study delves into the mechanical integrity of gas storage facilities and assesses the upper limit pressure for safe operation. Leveraging seismic logging data, we conducted an analysis and statistical evaluation of boundary faults and top cover characteristics, integrating regional stress fields and rock mechanics to evaluate fault activation pressure and cover failure risk using a fault activation pressure assessment method. This research elucidates the maximum safe operating pressure for underground gas storage facilities. The research findings suggest that the sealing layer of the Lei X gas storage reservoir exhibits a predominant hydro-fracturing pattern. Under the existing stress field conditions, the sealing layer demonstrates favorable sealing properties, and the boundary faults remain relatively stable. Moreover, through data extraction and quantitative analysis, this study clearly determined the critical pressure at which each fault is activated and the pressure at which the sealing layer undergoes hydro-fracturing during cyclic injection and the production of gas storage. Considering the activation pressure and fracturing pressure data for the sealing layer, a secure operating pressure of 15.0 MPa was calculated for gas storage operations. This study offers crucial theoretical support for enhancing injection and production efficiency, as well as ensuring the safe operation of Lei X gas storage and providing technical guidance for future adjustments to injection and production schemes.
Resilience Assessment of Urban Road Transportation in Rainfall

Published: September 2024

Transportation resilience, as a component of city sustainability, plays a crucial role in the daily management and emergency response of urban road systems. With coastal cities becoming increasingly vulnerable to typhoons, rainstorms, and other disasters, it is essential to assess the resilience of urban road transportation in a refined and differentiated approach. Existing resilience assessment methods often overlook significant biases, neglecting the dynamic response of road traffic and non-stationary characteristics of traffic systems. To address these limitations, we develop a quantitative resilience assessment method for urban road transportation during rainfall that is based on the improved Resilience Triangle. The method is applied to DiDi urban traffic speed and meteorological data of Shenzhen, China, from April to September 2018, with a focus on Typhoon Mangkhut as an extreme weather case. By analyzing transportation resilience variations across road densities, road hierarchies, and rainfall scenarios, we found that road densities and rainfall intensities explain resilience variations better than road hierarchies. Specifically, as accumulative precipitation exceeds 100 mm, a substantial surge in loss of performance is observed. Typhoon rainfalls result in a greater loss in urban road traffic compared to general rainfalls. The results offer valuable insights for urban road planning, traffic emergency management, and transportation resilience construction in the face of increasingly severe weather challenges.
Detection of Methane Leaks via a Drone-Based System for Sustainable Landfills and Oil and Gas Facilities: Effect of Different Variables on the Background-Noise Measurement
Authors: Tassielli Giuseppe , Cananà Lucianna , Spalatro Miriam
Published: September 2024

In recent years, thanks to the great diffusion of drone technology and the development of miniaturized sensors that can be connected to drones, in order to increase the sustainability of landfills and oil and gas facilities, interest in finding methane leaks and quantifying the relative flow has grown significantly. This operation requires the methane background concentration to be subtracted from the calculations. Therefore, in order to proceed with a right estimate of CH4 flows emitted, the possibility of correctly measuring or estimating the background level becomes crucial. The present work intends to illustrate the effects of different variables on the background-noise measurement in a drone-based system that uses a tunable diode laser absorption spectrometer (TDLAS). The methodology used is that of field testing; the data acquisition campaign consisted of the execution of 80 flights during which different flight variables (drone speed, flight altitude) were tested; the flights were repeated in different weather and climate conditions both during the same day and in different periods of the year. Different surfaces, similar to those found in landfill or natural gas sites, were also tested. In some of the field trials, a controlled methane release test was performed in order to verify how much the quantification of the methane flow can vary depending on the background level used. The results of the different field trials highlighted the best conditions under which to measure methane emissions with a TDLAS sensor in order to minimize the number of outliers: flight altitude not exceeding 15 m above ground level; the drone speed appears to have less impact on the results, however, it is optimal between 1 and 2 ms−1; a very sunny day produces much higher methane background levels than a cloudy one. The type of surface also significantly affects the measurement of background noise. Finally, tests conducted with a controlled methane release highlighted that different levels of background have a significant impact on the estimation of the methane flux emitted.
Using Digital Technology for the Sustainable Preservation of Clothing Heritage: A Virtual Reconstruction of the 1848/49 Uniform

Published: September 2024

This work deals with the sustainable reconstruction of the uniform of the National Guard of Maribor from 1848/49 with the aim of developing the pattern design of the jacket and trousers of which it consists of and making a virtual replica of it. The original uniform of the Maribor National Guard, which can no longer be restored and/or conserved, is kept in the Maribor Regional Museum, Slovenia. The reconstruction of the pattern design of the jacket and trousers was based on historical sources, analyses, measurements and the decomposition of the uniform. The virtual reconstruction of the uniform pattern design was carried out using the Optitex PDS 3D V11 programme. The construction proportions of the uniform’s basic pattern design were analysed to determine the basic body dimensions of the wearer of the jacket and trousers and to create 3D body models of the wearers using the standard 3D body model of the software used. This made it possible to create an accurate “3D body model–clothing” system that realistically represents the virtual replica of the uniform. The results of this research help to preserve, understand and explore the cultural heritage of clothing in a sustainable way and make it accessible to the public.
Registration System Reform and Enterprise Innovation: Evidence from a Quasi-Natural Experiment of the Registration-Based IPO System Reform Pilot in China
Authors: Cheng Fu , Kang Yuyang , Huang Jiayun
Published: September 2024

In recent years, the registration-based IPO system has been gradually introduced and promoted in China’s capital market, and its implementation effect has attracted considerable attention. This paper focuses on companies that were first listed between 2019 and 2021. We empirically investigate the impact of the registration system reform on enterprise innovation using the staggered difference-in-differences model, with R&D investment as the measure of enterprise innovation. The findings demonstrate that, in comparison to companies listed via the approval system, those listed via the registration system exhibit a higher level of R&D investment in the three years following listing. This suggests that the reform of the registration system effectively stimulates an increase in R&D investment among IPO companies. Furthermore, the reform of the registration system has been found to significantly promote the R&D investment of IPO companies on the STAR Market (i.e., the Science and Technology Innovation Board), while having no significant impact on the R&D investment of IPO companies on the ChiNext Market (i.e., the Growth Enterprise Board). Further analysis indicates that the registration system reform encourages IPO firms to increase R&D investment by reducing agency costs, alleviating financing constraints, and accumulating human capital. This study elucidates the impact of registration system reform on enterprise innovation and its mechanism and provides novel empirical evidence for the evaluation of the effect of registration system reform pilot.

The functioning of modern urban environments relies heavily on the public transport system. Given spatial, economic, and sustainability criteria, public transport in larger urban areas is unrivaled. The system’s role depends on the quality of service it offers. Achieving the desired service quality requires a design that meets transport demands. This paper uses a data-driven approach to address headway deviations in public transport lines and explores ways to improve regularity during the design phase. Headway is a critical dynamic element for transport organization and passenger quality. Deviations between planned and actual headways represent disturbances. On lines with headways under 15 min, passengers typically do not consult schedules, making punctuality less crucial. Reduced headway regularity affects the average travel time, travel time uncertainty, and passenger comfort. Ideally, the public transport system operates with regular headways. However, disturbances can spread and affect subsequent departures, leading to vehicle bunching. While previous research focused on single primary disturbances, this study, with the help of AI (reinforcement learning), examines multiple primary disturbances in the cities of Belgrade, Novi Sad, and Niš. The goal is to model the cumulative impact of these disturbances on vehicle movement. By ranking parameter influences and using the automatic optimization of static line elements, this research aims to improve headway regularity and increase system resilience to disturbances. The results of this research could also be useful in developing adaptive public transport management systems that leverage AI and IoT technologies to continuously optimize headway regularity in response to real-time data, ultimately enhancing service quality and passenger satisfaction.
Ecosystem Functions in Urban Stormwater Management Ponds: A Scoping Review
Authors: Marques Piatã , Mandrak Nicholas E.
Published: September 2024

Stormwater management ponds (SWMPs) are an important tool for sustainable urban stormwater management, controlling the quantity and quality of stormwater runoff in cities. Beyond their engineering purpose, SWMPs may hold ecological value that is often overlooked. This is especially the case for the array of geochemical, physical, and biological processes (i.e., ecosystem functions) in SWMPs. Here, we performed a scoping review of ecosystem function in SWMPs to summarize current knowledge and identify research needs. We searched peer-reviewed papers using the Web of Science database. Papers that did not report specifically on SWMPs, did not discuss ecosystem function, or were solely based on ecotoxicological tests were excluded from further assessment. For the remaining papers, information on year of publication, scope, and key findings was extracted. We found that a total of 55 papers on ecosystem function in SWMPs have been published since 1996. Our review identified important areas for advancing knowledge about nutrient dynamics, contaminants processing, sedimentation, temperature, habitat provisioning, and biodiversity in SWMPs. Overall, we identified a need to further understand how factors related to pond design and landscape and management practices influence ecosystem function. There is also a need to understand the effect of climate change on ecosystem function and to examine the interactions between ecosystem function and humans. Such information will not only provide opportunities for researchers to better understand ecological value, but also facilitate more effective sustainable management of SWMPs.
Integrating Design for Adaptability, Disassembly, and Reuse into Architectural Design Practice

Published: September 2024

Increased timber construction is putting pressure on Ireland’s limited structural-grade timber stock, while recovered timber is currently downcycled or incinerated. Design for Adaptability, disassembly and reuse (DfADR) has emerged as a response to this wasteful linear process, which can increase the life span of structures, the ease of disassembly during and after use, and improve the quality of recovered material. However, while many DfADR strategies have been identified, uptake in architectural practice is lacking. Impediments to DfADR were identified through an analysis of an existing timber-framed structure and a modified design developed based on the ISO 20887:2020 principles to illustrate practical solutions. In tandem, a decision tool was developed that organised the plethora of identified strategies by the ISO principles and the work stages used by designers to facilitate integration into practice. Modest reconfigurations of the space and roof structure increased adaptability, access to services for replacement and repair, and expansion potential to increase service life, while rationalized timber sizes improved reuse potential. Using wood nails in stud and joist framing, with screws replacing nails elsewhere, and omitting adhesives from the floor panels increased the ease of disassembly. These relatively minor changes resulted in nearly 3 times the amount of solid timber with a high reuse potential (≥2348 mm) recovered over the original design, highlighting the impact DfADR can have on the recoverability and reusability of timber.

Vietnam is a country highly vulnerable to climate change. Specifically, climate change has seriously impacted all aspects of Vietnam’s economic and social life, especially agricultural production. In this article, we focus on analyzing the current situation and the impacts of climate change on agricultural production and food security in Vietnam, especially in the Mekong River Delta (MRD) region. Vietnam’s climate change scenarios (RCP4.5 and RCP 8.5) have warned of serious increases in temperature, rainfall, and sea level rises for the MRD in coming times. This will lead to a risk of flooding in nearly 50% of the region’s area and will seriously affect agricultural production in many aspects such as soil quality degradation, scarcity of water resources, increased droughts and floods, reduced crop productivity, and so on. These impacts will reduce Vietnam’s food supply capacity, but do not compromise national food security from a short-term perspective. Faced with this situation, the Government of Vietnam has implemented many comprehensive measures to transform agriculture towards ecology, sustainability, and low carbon emissions, with the goal of green growth and neutral carbon emissions by 2050. In particular, the focus is on combining nature-based solutions with the application of modern science and technology in agricultural production, raising awareness and the response capacity of domestic people, with international cooperation in addressing climate change issues.
Assessing the Role of Self-Efficacy in Reducing Psychological Reactance to Guilt Appeals Promoting Sustainable Behaviors

Published: September 2024

Guilt is a widely used emotional appeal in environmental sustainability and other advocacy messages. However, unintended negative effects such as psychological reactance, where individuals resist or reject the message, have been identified, and scholars have recently suggested strategies to mitigate those effects. Using an experimental design, the study examined the role of self-efficacy cues (lower vs. higher magnitude behavioral recommendations) in the message recommendation component of guilt appeals that are designed to elicit more guilt than shame. Adult-aged participants (N = 341) were exposed to messages that described the negative effects of climate change on wild animals. Results from a serial mediation test indicated that viewing guilt messages with lower (vs. higher) magnitude behavioral recommendation was associated with greater self-efficacy beliefs and less perceived threat to freedom, which predicted more anticipated guilt and, finally, greater intention to take pro-environmental actions. These findings contribute to the theoretical development and practical applications regarding how self-efficacy-enhancing content in guilt appeals can reduce defensive responses and foster a stronger commitment to sustainable practices.
