Published: September 2024

Background: The pollution of organophosphate flame retardants (OPFRs) is of global concern, but the site-specific data of OPFR concentrations in drinking water are scarce for many areas of the world outside of Europe and the US. This study aimed to investigate the occurrence and profiles of OPFRs in the tap water treatment and delivery process in Shanghai. Methods: In total, 106 samples were analyzed for 10 OPFRs, which were collected periodically from monitoring points of drinking water treatment plants and piped water between November 2021 and July 2023. The average daily doses of OPFRs through the ingestion of tap water were calculated by multiplying nominal volumes of water ingestion rates with the measured concentrations of OPFRs. Hazard quotients, the hazard index, and the carcinogenic risks of OPFRs via drinking water were used to estimate the health risks. Results: Tributyl phosphate (TBP), tris(2-chloroethyl) phosphate (TCEP), and tris (1-chloro-2-propyl) phosphate (TCIPP) were found in >90% of the tap water samples, whereas triethyl phosphate (TEP) and tris (2,3-dibromopropyl) phosphate (TDBPP) were not found in any samples. The concentrations of Σ10OPFRs were found at part-per-trillion ranges, with average concentrations that ranged from 86.0 ng/L in February 2023 (dry season) to 218 ng/L in July 2022 (wet season). TCIPP was the most abundant compound among the investigated OPFRs. The average daily dose of Σ10OPFRs via the ingestion of tap water was up to 20.4 ng/kg body weight/day. The hazard quotients of OPFRs through drinking water were in the range of 10−5–10−4, indicating low risk levels. Moreover, the hazard index of OPFRs indicated that the risk for children (2 × 10−4) was higher than adults (7 × 10−5). Conclusion: Tap water intake may be an important source of OPFRs exposure. But the risk of OPFRs for local residents is at a low level through drinking water.

Authors: Hammond Harriet L. , Roy Chad J.
Published: September 2024

Palytoxins are a group of highly potent and structurally complex marine toxins that rank among some of the most toxic substances known to science. Palytoxins are naturally synthesized by a variety of marine organisms, including Palythoa zoanthids, Ostreopsis dinoflagellates, and Trichodesmium cyanobacteria, and are widely distributed in tropical and temperate regions where they can bioaccumulate in marine life. The evolution of research on palytoxins has been an intricate exchange between interdisciplinary fields, drawing insights from chemistry, biology, medicine, and environmental science in efforts to better understand and mitigate the health risks associated with this family of toxins. In this review, we begin with a brief history covering the discovery of this group of toxins and the events that led to its isolation. We then focus on the chemical structure of these compounds and their proposed mechanism of action. Finally, we review in vitro, ex vivo, and in vivo studies related to their toxicity, with the aim to provide a broad overview of the current knowledge on palytoxin toxinology.

We discuss the potential usefulness of molecular testing of soil, dust, and water samples to detect medically important parasites, and where such testing could be used to supplement stool sampling in humans. A wide variety of parasites including protozoa and helminths, many of which are zoonotic, have an important infection reservoir in the environment. In some cases, this environmental period is essential for further parasite development. We describe the progress in implementing methods for the molecular detection of these parasites in soil across eight collaborating centers in Latin America and represent a variety of potential applications in improving our understanding of parasite epidemiology and mapping, surveillance, and control of these parasites. This methodology offers new opportunities for improving our understanding of a wide variety of parasites of public health importance and novel tools for their control.
Cascading Failure and Resilience of Urban Rail Transit Stations under Flood Conditions: A Case Study of Shanghai Metro
Authors: Li Dekui , Hou Yuru , Du Shubo , Zhou Fan
Published: September 2024

The increasing frequency of urban flooding, driven by global climate change, poses significant threats to the safety and resilience of urban rail transit systems. This study systematically examines the cascading failure processes and resilience of these networks under flood conditions, with a specific focus on the Shanghai Metro. A comprehensive resilience evaluation model was developed by integrating geographic information, static network characteristics, and dynamic passenger flow indicators. This study employs an improved Coupled Map Lattice (CML) model to simulate cascading failures by considering the coupling effects of station centrality, geographic elevation, and passenger flow dynamics. The results indicate that stations with higher degrees of centrality are more likely to trigger rapid cascading failures across the network. However, incorporating dynamic passenger flow and geographic elevation data helps mitigate these effects, emphasizing the need for multi-dimensional resilience strategies. The findings provide valuable insights for urban transit management, offering a scientific foundation for developing targeted disaster response strategies to enhance network resilience against floods. This study advances our understanding of the vulnerability of urban rail transit systems and offers practical guidance for improving disaster preparedness in urban transportation infrastructure.

Published: September 2024

The aim of this work was to determine the concentrations, distribution, and fate of potentially toxic elements [lead (Pb), zinc (Zn), nickel (Ni), copper (Cu), mercury (Hg), arsenic (As), and cadmium (Cd)] in sediments of a hydropower plant water reservoir located in the Brazilian Cerrado biome (used as system model). The purpose of this study was achieved with an analysis of the level of contamination based on the geoaccumulation index (Igeo) and factor contamination (FC) and comparisons with values established by environmental legislation. The physical–chemical–biological properties of sediment samples, the distribution, and the fate of potentially toxic elements (PTEs) in the basin of the stream studied were also investigated using Pearson’s correlation coefficient (r) and principal component analysis (PCA). Cu, Hg, and Cd concentrations in the sediment samples from most of the points analyzed were above level II of the categorization stipulated in environmental legislation, characterizing sediments of poor quality. Moreover, Igeo and FC values indicated potential pollution of the water reservoir sediment by Cd. Concentrations of Cd exceeding 0.34 mg kg−1 surpassed the reference values for water quality established by Conama Resolution No. 454/2012, highlighting the urgent need for ongoing sediment quality monitoring strategies. Hence, the study water reservoir was classified as being moderately to extremely polluted due to the fate of potentially toxic metals in the sediment samples. Frequent monitoring of the sediment quality in watersheds with hydropower plants is indispensable for the assessment of water resources, considering the importance of the water supply and power generation for the population. Moreover, water contaminated by PTEs poses potential risks to river basins, as well as to human and animal health. The results of this work can assist in the investigation of other water reservoirs around the world.

An experiment was conducted to investigate the optimal use of high-salt water for alfalfa fodder growth and quality in Aridisol. The experiment included five treatments and was performed using a completely randomized design (CRD) as factorial design with three replications. We used a leaching fraction technique (LF), which is a mitigating technique (MT). The five treatments were T1 = MT1 as normal irrigation (control), T2 = MT2 as a leaching fraction (LF) of 15% with the same quality of water, T3 = MT3 as a LF of 30% with the same quality of water, T4 = MT4 as a LF of 15% with good-quality water (as percentage of total water), in the form of 2–3 irrigations every 3 months, and T5 = MT5 as a LF of 30% with good-quality water (as percentage of total water), in the form of 2–3 irrigations every 3 months. The duration of the experiment was three years and normal soil (non-saline, non-sodic) was used in the current study. Results showed that saline water irrigation negatively affected the growth traits, but the application of the LF technique with same-quality or good-quality water mitigated such negative effects. The fodder quality traits such as crude protein (CP), crude fiber (CF) and ashes were also affected in a negative way with the use of saline irrigation water. This negative impact was more intensified in the third year as the concentration of salts increased in saline water during the three years of the current investigation. A LF with canal water at 15 or 30% reduced the negative effects of salt stress and improved fodder biomass production and quality traits. For examples, using a LF with canal water at 30% increased the biomass production to 33.30 g and 15.87 g when plants were irrigated with W1 and W5, respectively. In addition, it improved quality traits such as crude protein content (5.54% and 3.73%) and crude fiber content (14.55% and 12.75%) when plants were irrigated with W1 and W5, respectively. It was concluded that the LF technique can be recommended for practice in the case of saline water irrigation for the optimized growth and quality of alfalfa fodder.

Modelling at the basin scale offers crucial insights for policymakers as they make decisions regarding the optimal utilization of water resources. This study employed the MIKE HYDRO Basin model to analyse water demand and supply dynamics in the Parvati Basin of Rajasthan, India, for the period 2005–2020. The MIKE11 NAM model showcased strong alignment between simulated and observed runoff during both the calibration (NSE = 0.79, PBIAS = −2%, R2 = 0.79, RMSE = 4.95, RSR = 0.5, and KGE = 0.84) and validation (NSE = 0.67, PBIAS = −12.4%, R2 = 0.68, RMSE = 8.3, RSR = 0.62, and KGE = 0.67) phases. The MIKE HYDRO Basin model also exhibited excellent agreement between observed and simulated reservoir water levels, with R2, NSE, RMSE, PBIAS, RSR, and KGE values of 0.86, 0.81, 3.87, −2.30%, 0.43, and 0.88, respectively. The MIKE HYDRO Basin model was employed to create six distinct scenarios, considering conveyance efficiency, irrigation method, and conjunctive water use, to assess irrigation demands and deficits within the basin. In the initial simulation, featuring a conveyance efficiency of 45%, flood irrigation, and no groundwater utilization, the average water demand and deficit throughout the study period were estimated as 43.15 MCM and 3.45 MCM, respectively, resulting in a sustainability index of 0.506. Enhancing conveyance efficiency to 75% under flood irrigation and 5% conjunctive use could elevate the sustainability index to 0.92. Transitioning to sprinkler irrigation and a lift irrigation system could raise the system’s sustainability index to 1. These developed models hold promise for real-time reservoir operation and irrigation planning across diverse climatic conditions and varying cropping patterns.

Published: September 2024

The article explores the fundamental requirements for microservice architecture in information systems and justifies its suitability for e-commerce information systems. The concept of micro-service architecture is based on developing software applications as a collection of independent modular services aligned with business capabilities and priorities. The characteristics of service interaction and factors influencing architectural decisions are discussed. Microservice architec-ture's flexibility to employ different technologies and platforms for individual services is high-lighted, allowing the adaptation of technical solutions to the unique needs of each service. Func-tional, non-functional, and business requirements for e-commerce systems are defined, and an architectural approach for web services is proposed. This approach is based on a client-server and microservice architecture, enabling both horizontal and vertical scaling of the server-side components. The architecture involves creating separate services to correspond to distinct busi-ness functions, facilitating further scalability and expansion since each microservice can be de-ployed independently. A list of business requirements for microservices in an e-commerce in-formation system, along with the specifications for their implementation, has been formed. An app architecture for the e-commerce system is presented, comprising a collection of micro-services that collectively constitute a comprehensive e-commerce system, and the tools for practical implementation are justified. This architecture effectively embodies the advantages of the microservices development approach, allowing the system to dynamically adapt to changing business needs. It provides scalability and simplifies system maintenance, rendering it more agile and prepared to meet the challenges of modern business and technology.

Published: September 2024

The paper analyzes the rapidly growing importance of graph and network models and tools in such areas as transport, communications, social and military systems, goods production and distribution, education, economy, biology, psychology, criminology, climate change, etc. It aims at the development of effective methods capable of integrating different types of networks into higher-level infrastructures representing advanced social systems, particularly considering the symbiosis of goods production, goods evaluation, and the obtained product delivery systems under some universal networking concept. In a search for the latter, the article briefs the developed and patented Spatial Grasp Model and Technology (SGT) with its basic Spatial Grasp Language (SGL), which allow for fully distributed and parallel operations on arbitrary large and complex networked structures. The paper first shows some elementary networking operations in SGL useful for a better understanding of the rest of the material. Then it provides several practical examples of combined networking solutions, which include scenarios in SGL for finding the strongest production centers in their networks, as well as the most powerful user communities interested in and requesting particular types of products. After the selection of specific producers and consumers, the paper forms a distributed virtual and physical delivery infrastructure oriented on all of them and based on the shortest paths from producers to consumers and shows live the distribution process in SGL. The obtained results confirm that the deep integration of heterogeneous distributed systems can be organized naturally and automatically within the global integrity, awareness, and consciousness processes under the Spatial Grasp paradigm, as was already discussed in the previous publications on SGT.
Carbon Storage Assessment under Mangrove Restoration of Dongzhai Harbor in Hainan Island, China
Authors: Zhu Yuxin , Jia Peihong , Zhang Zhouyao , Cheng Jiaxuan , Wang Na
Published: September 2024

Mangrove restoration is recognized as an effective strategy for enhancing the carbon storage capacity of natural ecosystems, advancing toward the “carbon neutrality” goal. The carbon storage effects of ecological restoration efforts remain insufficiently understood as previous studies have focused on carbon storage dynamics in ecosystems, yet the specific impacts of targeted mangrove restoration are less explored. This study utilizes multi-temporal remote sensing data and actual restoration data from Dongzhai Harbor Hainan Island to identify the mangrove wetland coverage and quantify the spatiotemporal evolution of carbon storage under various restoration efforts using the InVEST model. Additionally, we employed the PLUS model to simulate and compare carbon storage potential under multiple development goals. The findings reveal the following: (a) Mangrove restoration significantly increased the area of land with high carbon sink capability, resulting in a regional carbon storage increase of 210,001.68 tons from 2015 to 2021, with 97% of this increase attributable to ecological restoration. (b) Mangrove coverage is crucial for regional carbon storage, with an average of 443 tons of carbon stored per hectare. Decreases in carbon storage occurred mainly during the conversion of mangroves to aquaculture, and forests/agriculture to residential areas. Increases in carbon storage were seen in the reverse transitions. (c) Comparing the scenarios focused solely on mangrove protection with cultivated land protection, the carbon storage in Dongzhai Harbor is projected to reach its maximum by 2045 under the carbon storage priority scenario. Our findings build a scientific foundation for formulating effective mangrove conservation and restoration strategies.
Collision Lesions in Head and Neck Area: A Retrospective Study of 97 Reported Cases
Authors: Irani Soussan , Lam Alfred
Published: September 2024

Background: Collision (hybrid) lesions consist of two or more distinct histologic types occurring separately but within the same area. This review focuses on discussing all related and available case reports of hybrid lesions in the head and neck area. Methods: The literature was searched using several databases, including Scopus, Web of Science, PubMed, and Google Scholar. Papers published from 1990 to 2022 with full text available were considered for inclusion in the study. For a more comprehensive understanding, all lesions were categorized into cutaneous, jaw, and salivary gland groups and lesions in miscellaneous tissues. Results: In general, 97 reported collision lesions developed in the head and neck region. Among them, 31 (32%) and 34 (35%) cases were cutaneous hybrid lesions and in the jaws, respectively. In addition, 27 (27.8%) and 5 (5.1%) cases were in salivary glands and miscellaneous tissues, respectively. Conclusion: While the presence of true hybrid tumors is well-established, some reported cases have prompted researchers to categorize them as biphasic differentiations. The rarity of these cases contributes to limited knowledge regarding their clinical behavior, prognosis, and optimal treatment. It is crucial to emphasize the characteristic and potentially perplexing histological appearances.

Published: September 2024

Diabetes mellitus (DM) is an accumulation of glucose in the blood. Diabetic mellitus is divided into gestational diabetes, type 1 and type 2. Complications of diabetes mellitus include diabetic foot ulcers. The most important complication of diabetic foot ulcers is bacterial infection, which leads to gangrene when various types of antibiotics fail to prevent bacterial infections. To explore the effect of synthetic zinc oxide nanoparticles (ZnONPs) on the expression of the MagA gene in Klebsiella pneumoniae isolated from diabetic foot ulcer cases. ZnONPs were biosynthesized by Aspergillus niger and characterized using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), X-ray diffraction (XRD), and UV-visible spectroscopy. The inhibitory effect of ZnONPs on K. pneumoniae isolates was examined by determining the minimum inhibitory concentration (MIC) of the ZnONPs. Besides, the values of the MagA gene before and after exposure to ZnONPs would be examined by RT-qPCR, with 16SrRNA gene as the reference gene. According to SEM and XRD results, the ZnONPs are in the form of nanocrystals and have small spherical crystals with an average size of 13.5 nm. The highest optical density of the synthesized nanoparticles was obtained at 390 nm. The biosynthesized ZnONPs exhibit a strong inhibition zone against K. pneumoniae corresponding to 125 μg/mL. The fold of gene expression ranged from 0.042 to 0.118. The research reveals that ZnONPs exhibit strong antibacterial potential and affect gene expression in K. pneumoniae strains. The results of the present study indicate that ZnONPs can indeed be used in the treatment of infectious bacteria.

Published: September 2024

Shock freezing using the acoustic method is the most efficient and fastest way to freeze food. However, the devices used for this purpose are characterized by such disadvantages as the immobility of the frozen product, the inability to change the operating parameters of the freezing agent and acoustic generators in accordance with the thermodynamic and biochemical changes in the product during the freezing process, and the impossibility of a quick and easy transition from processing one type of food product to the end. A new design of the device for acoustic freezing is presented, which ensures the use of the working agent and acoustic generators with the most acceptable parameters corresponding to changes in the product during the process of freezing the product, and ensures the constant movement of the product relative to the processing agent and generators throughout the entire process. This design significantly increases the efficiency and speed of product processing, increases productivity and prevents mechanical damage to the product.

In the modern world, an innovative society is gradually formed based on the spread and use of knowledge. Educational and scientific research institutions occupy a central place in the process of knowledge circulation. The problems related to the process of their integration are identified in the present paper (on the example of Georgian), a comparative analysis of the international practice of situational and research activities, legislative gaps and prospects for promoting the development of science are presented. Acknowledging the fact that universities play a special role in creating and transferring knowledge that is based on science and technology, the importance and relevance of the research topic are beyond doubt. The meaningful integration of higher education, science, technology and industry is a step-by-step process and mainly considers the creation of an innovative ecosystem, training of human resources and an appropriate legal base. The goal of our research is to present conceptual issues that contribute to the development of science in our country, for which, together with the situational analysis, recommendations are offered at the end of the paper to solve the problems identified in the research process.

The success of construction projects hinges on many other elements outside the common indicators of time, cost and quality. Cultural factor as an important success factor is therefore enjoying a critical look from all stakeholders in the construction industry across the globe. This paper serves the purpose of examining the dominance, role and contribution of factors of organisational culture (OC) on the successful delivery of construction projects in Nigeria. The research design was that of a quantitative survey approach with a questionnaire used for eliciting responses from 1233 respondents. The feedback from 975 respondents was analysed using Kruskal Wallis Test. The findings show three factors namely; people are permitted to find solutions to the same issues in different ways (Innovative culture); leadership has great regard for individual ability to do things creatively (Supportive culture); the condition of service in this organisation is fair to the staff (Supportive culture). These three factors are essential in project success.

Introduction. The World Health Organization considers the values of antibody titers in the hemagglutination inhibition assay as one of the most important criteria for assessing successful vaccination. Mathematical modeling of cross-immunity allows for identification on a real-time basis of new antigenic variants, which is of paramount importance for human health.
Materials and methods. This study uses statistical methods and machine learning techniques from simple to complex: logistic regression model, random forest method, and gradient boosting. The calculations used the AAindex matrices in parallel to the Hamming distance. The calculations were carried out with different types and values of antigenic escape thresholds, on four data sets. The results were compared using common binary classification metrics.
Results. Significant differentiation is shown depending on the data sets used. The best results were demonstrated by all three models for the forecast autumn season of 2022, which were preliminary trained on the February season of the same year (Auroc 0.934; 0.958; 0.956, respectively). The lowest results were obtained for the entire forecast year 2023, they were set up on data from two seasons of 2022 (Aucroc 0.614; 0.658; 0.775). The dependence of the results on the types of thresholds used and their values turned out to be insignificant. The additional use of AAindex matrices did not significantly improve the results of the models without introducing significant deterioration.
Conclusion. More complex models show better results. When developing cross-immunity models, testing on a variety of data sets is important to make strong claims about their prognostic robustness.

Introduction. Rotavirus infection is the major cause of severe dehydrating diarrhea requiring hospitalization in young children worldwide. Due to their segmented genome, rotaviruses are capable of gene reassortment, which makes the emergence and spread of genetically novel strains possible. The purpose of this study was to search for unusual rotaviruses circulating in Nizhny Novgorod in 2021‒2023 and their molecular genetic characterization based on all genome segments.
Materials and methods. Rotavirus-positive stool samples of children were examined by PCR genotyping and electrophoresis in PAAG. cDNA fragments of each of the 11 genes (VP1‒VP4, VP6, VP7, NSP1‒NSP5), 570 to 850 nucleotide pairs in length were sequenced for the selected strains. The phylogenetic analysis was performed in the MEGA X program.
Results. In the study period 2021‒2023, 11 G[P] combinations with a predominance of G3P[8] (59.5%) were identified. Six atypical Rotavirus А (RVA) strains were identified: 2 strains of the G2P[4] genotype (G2-P[4]-I2-R2-C2-M2-A3-N2-T3-E2-H3, G2-P[4]-I2-R2-C2-M2-A3-N2-T3-E3-H2) and 4 G3P[9] strains (all strains had the genotype G3-P[9]-I2-R2-C2-M2-A3-N2-T3-E3-H3). Phylogenetic analysis based on all genes showed an evolutionary relationship between rotaviruses similar to rotaviruses of cats and dogs (BA222-like) and unusual strains of the G2P[4] genotype, for which a mixed combination of genotypes was identified and characterized for the first time.
Discussion. The results obtained expand the understanding of the diversity of reassortant RVAs, as well as complement the data on the genotypic structure of the rotavirus population in Nizhny Novgorod.
Conclusion. The wide genetic diversity of reassortant RVA can help rotaviruses overcome the immunological pressure provided by natural and vaccine-induced immunity. In this regard, to control the emergence of new variants and assess changes in the virulence of rotaviruses after reassortment processes, continuous molecular monitoring for circulating RVA is necessary.

This article discusses inclusive educational policies for students with disabilities in higher education. In methodological terms, documentary research was carried out on the inclusion of public students of special education (PEE) of the IF Goiano, prepared in the period from 2015 to 2022. The focus was to analyze and understand how access, permanence and support has been given to these students enrolled in undergraduate courses. The data were analyzed from a qualitative perspective, establishing axes of analysis based on the research objectives. The results revealed, among other aspects, that the challenges are numerous, among which we can mention the lack of financial and human investments for the support that part of these students need, the absence of effective teachers to act in the support, the lack of clarity of the pedagogical practices accessible to PEE students. Despite these difficulties, the research revealed that the institutional policies aimed at PEE students at the IF Goiano have been translated following the guidelines of federal policies in the area.

Digital accessibility remains a critical challenge for the full inclusion of people with disabilities, especially in a context where technology plays a central role in everyday life. In this sense, a web system, currently in beta version, which assesses the compliance of websites with the accessibility guidelines of the Web Content Accessibility Guidelines (WCAG), was created to act as a digital accessibility monitor. The objective of the system is to ensure that public websites meet accessibility standards and promote digital inclusion. The methodology involved the development of software that performs automated analysis of websites based on WCAG principles: perceivable, operable, understandable and robust. After implementation and rigorous testing, the system began evaluating websites and generating detailed reports on their level of compliance. The results revealed that the majority of sites evaluated are in the 41%-60% accessibility range, with few reaching higher ranges. These findings highlight a critical need for substantial improvements in digital accessibility, pointing to the importance of ongoing monitoring and adoption of best practices to achieve a truly inclusive web. Final considerations highlight the urgent need for corrective actions and the importance of promoting a culture of accessibility, encouraging the implementation of guidelines more broadly and consistently to ensure that all users can access and use the internet fully and effectively.

This article aims to explain teaching professionalism from the perspective of inclusive education in the context of higher education, establishing dialogues with the Theory of Social Representations (TRS). In this work, we adopted a qualitative approach, through an exploratory and bibliographical study, whose content sheds light on why the perceptions, senses and meanings of university teachers, around their professionalism for inclusive education, comprise a relevant phenomenon of social thickness, decisive to be considered when idealizing a pedagogical practice that materializes the social and educational ideals of education from an inclusive perspective, in the context of a higher education institution. The research was carried out on a national and international scale in the SciELO, Web of Science, SCOPUS and Digital Library of Theses and Dissertations databases, in a time frame from 2017 to 2023 and adopting the areas of Social Sciences, Education, Arts as search criteria. and Humanities and the following key words: teacher training, continuing training, inclusive education, people with disabilities and higher education. The results indicated a fertile field of studies, given the incipient productions around the nexus of teaching professionalism and inclusive education, particularly in the context of higher education.
