Avian malaria is expanding upslope with warmer temperatures and driving multiple species of Hawaiian birds towards extinction. Methods to reduce malaria transmission are urgently needed to prevent further declines. Releasing Wolbachia-infected incompatible male mosquitoes could suppress mosquito populations and releasing Wolbachia-infected female mosquitoes (or both sexes) could reduce pathogen transmission if the Wolbachia strain reduced vector competence. We cleared Culex quinquefasciatus of their natural Wolbachia pipientis wPip infection and transinfected them with Wolbachia wAlbB isolated from Aedes albopictus. We show that wAlbB infection was transmitted transovarially, and demonstrate cytoplasmic incompatibility with wild-type mosquitoes infected with wPip from Oahu and Maui, Hawaii. We measured vector competence for avian malaria, Plasmodium relictum, lineage GRW4, of seven mosquito lines (two with wAlbB; three with natural wPip infection, and two cleared of Wolbachia infection) by allowing them to feed on canaries infected with recently collected field isolates of Hawaiian P. relictum. We tested 73 groups (Ntotal = 1176) of mosquitoes for P. relictum infection in abdomens and thoraxes 6–14 days after feeding on a range of parasitemias from 0.028% to 2.49%, as well as a smaller subset of salivary glands. We found no measurable effect of Wolbachia on any endpoint, but strong effects of parasitemia, days post feeding, and mosquito strain on both abdomen and thorax infection prevalence. These results suggest that releasing male wAlbB-infected C. quinquefasciatus mosquitoes could suppress wPip-infected mosquito populations, but would have little positive or negative impact on mosquito vector competence for P. relictum if wAlbB became established in local mosquito populations. More broadly, the lack of Wolbachia effects on vector competence we observed highlights the variable impacts of both native and transinfected Wolbachia infections in mosquitoes.

SARS-CoV-2 spike protein (SARS-2-S) induced cell–cell fusion in uninfected cells may occur in long COVID-19 syndrome, as circulating SARS-2-S or extracellular vesicles containing SARS-2-S (S-EVs) were found to be prevalent in post-acute sequelae of COVID-19 (PASC) for up to 12 months after diagnosis. Although isolated recombinant SARS-2-S protein has been shown to increase the SASP in senescent ACE2-expressing cells, the direct linkage of SARS-2-S syncytia with senescence in the absence of virus infection and the degree to which SARS-2-S syncytia affect pathology in the setting of cardiac dysfunction are unknown. Here, we found that the senescent outcome of SARS-2-S induced syncytia exacerbated heart failure progression. We first demonstrated that syncytium formation in cells expressing SARS-2-S delivered by DNA plasmid or LNP-mRNA exhibits a senescence-like phenotype. Extracellular vesicles containing SARS-2-S (S-EVs) also confer a potent ability to form senescent syncytia withoutde novosynthesis of SARS-2-S. However, it is important to note that currently approved COVID-19 mRNA vaccines do not induce syncytium formation or cellular senescence. Mechanistically, SARS-2-S syncytia provoke the formation of functional MAVS aggregates, which regulate the senescence fate of SARS-2-S syncytia by TNFα. We further demonstrate that senescent SARS-2-S syncytia exhibit shrinked morphology, leading to the activation of WNK1 and impaired cardiac metabolism. In pre-existing heart failure mice, the WNK1 inhibitor WNK463, anti-syncytial drug niclosamide, and senolytic dasatinib protect the heart from exacerbated heart failure triggered by SARS-2-S. Our findings thus suggest a potential mechanism for COVID-19-mediated cardiac pathology and recommend the application of WNK1 inhibitor for therapy especially in individuals with post-acute sequelae of COVID-19.

Published: August 2024

Flexible esophagogastroduodenoscopy is the gold standard for the management of acute upper gastrointestinal bleeding. This is a case of a man who was admitted in the emergency department because of melena with hypotension because of an ulcer in the anterior face of the duodenal bulb, refractory to 3 attempts of endoscopic therapy. Then, a gastroduodenal arterial embolization was tried, being impossible because of the presence of the median arcuate ligament, compressing the celiac trunk. A balloon-expandable stent was inserted in the celiac trunk, and then, the embolization was performed. After unsuccessful endoscopic management, the arterial embolization is one of the treatment options in nonvariceal acute upper gastrointestinal bleeding.

Authors: Maryudi Maryudi , Hakika Dhias Cahya , Amillia Amillia
Published: August 2024

Microporous membranes were obtained by dry-wet phase inversion from a solution of cellulose acetate (CA) in acetone (13, 14 and 15 wt%). Polyethylene glycol was used as a blowing agent. The structure and mechanical properties were examined. FT-IR spectra show that the addition of polyethylene glycol improves the thermodynamics of the solution and increases the hydrophilicity of the membrane. The SEM method confirmed the microporous structure of membranes with an asymmetric structure and various pore sizes and porosities. Higher CA concentration resulted in better tensile properties.

Teacher Trainers’ and Curriculum Development Experts’ Perspectives on Information Technologies Curriculum in Teacher Education
Authors: Gençel Nurgün , Fidan Mustafa
Published: August 2024

This mixed-method study had two purposes: (1) to explore the appropriateness of the learning outcomes of information technologies (IT) course curriculum in teacher education programs based on the opinions of curriculum development experts and (2) to evaluate the opinions of the academics about the adequacy of this curriculum. Curriculum development experts (n = 5) evaluated the learning outcomes of the IT course curriculum followed by the education faculties of 25 universities in Türkiye in terms of their qualitative relevance. We also obtained the opinions of 10 academics in these faculties for the evaluation of the IT course curriculum. To collect data, we used the “Qualitative Eligibility Form for Learning Outcomes” and “Evaluation Form for IT Curriculum”. We employed descriptive statistics in the analysis of quantitative data while qualitative data were analysed using content analysis. The results showed that most of the learning outcomes in the IT course curriculum were not sufficient for the criteria of formal spelling conformity, necessity, and encouragement of higher-order thinking. The academics’ perspectives revealed that course sessions and practical learning activities in the IT curriculum were not sufficient. They suggested that emerging technologies such as artificial intelligence, Web 2.0/3.0 tools, robotics, coding, and augmented/virtual reality should be integrated into the curriculum. The implications for IT curriculum in teacher education programs and recommendations for future research were also discussed.

Published: August 2024

The place of civics in lower secondary education is somewhat at odds with the demands that the current political, economic, and environmental situation places on citizens regarding their preparation for life. In this text, we have focused on analyzing approaches to civic education from an international perspective. We have analyzed the Czech practice of civic education from 1992 to the present based on the analysis of internationally discussed types of teaching civic education and basic social sciences and selected key curriculum documents. Using an illustrative analysis of selected textbooks’ content, we could point out problematic areas of the still valid curriculum and differences in content between the curriculum and practice.

Well-posedness of Cauchy problem of fractional drift diffusion system in non-critical spaces with power-law nonlinearity
Authors: Gu Caihong , Tang Yanbin
Published: August 2024

In this article, we consider the global and local well-posedness of the mild solutions to the Cauchy problem of fractional drift diffusion system with higher-order nonlinearity. The main difficulty comes from the higher-order nonlinearity. Instead of the convention that people always focus on the properties of the solution in critical spaces, here we are interested in non-critical spaces such as supercritical Sobolev spaces and subcritical Lebesgue spaces. For the initial data in these non-critical spaces, using the properties of fractional heat semigroup and the classical Hardy-Littlewood-Sobolev inequality, we obtain the existence and uniqueness of the mild solution, together with the decaying rate estimates in terms of time variable.
Clinical utility of personalized reference intervals for CEA in the early detection of oncologic disease
Authors: Martínez-Espartosa Débora , Alegre Estíbaliz , Casero-Ramírez Hugo , Díaz-Garzón Jorge , Fernández-Calle Pilar , Fuentes-Bullejos Patricia , Varo Nerea , González Álvaro
Published: August 2024

Objectives

Personalized reference intervals (prRI) have been proposed as a diagnostic tool for assessing measurands with high individuality. Here, we evaluate clinical performance of prRI using carcinoembryonic antigen (CEA) for cancer detection and compare it with that of reference change values (RCV) and other criteria recommended by clinical guidelines (e.g. 25 % of change between consecutive CEA results (RV25) and the cut-off point of 5 μg/L (CP5)).

Methods

Clinical and analytical data from 2,638 patients collected over 19 years were retrospectively evaluated. A total 15,485 CEA results were studied. For each patient, we calculated prRI and RCV using computer algorithms based on the combination of different strategies to assess the number of CEA results needed, consideration of one or two limits of reference interval and the intraindividual biological variation estimate (CVI) used: (a) publicly available (CVI-EU), (b) CVI calculated using an indirect method (CVI-NOO) and (c) within-person BV (CVP). For each new result identified falling outside the prRI, exceeding the RCV interval, RV25 or CP5, we searched for records identifying the presence of tumour at 3 and 12 months after the test. The sensitivity, specificity and predictive power of each strategy were calculated.

Results

PrRI approaches derived using CVI-EU, and both limits of reference interval achieve the best sensitivity (87.5 %) and NPV (99.3 %) at 3 and 12 months of all evaluated criteria. Only 3 results per patients are enough to calculate prRIs that reach this diagnostic performance.

Conclusions

PrRI approaches could be an effective tool to rule out new oncological findings during the active surveillance of patients.

Automated sex and age partitioning for the estimation of reference intervals using a regression tree model
Authors: Klawitter Sandra , Böhm Johannes , Tolios Alexander , Gebauer Julian E.
Published: August 2024

Objectives

Reference intervals (RI) play a decisive role in the interpretation of medical laboratory results. An important step in the determination of RI is age- and sex specific partitioning, which is usually based on an empirical approach by graphical representation. In this study, we evaluate an automated machine learning approach.

Methods

This study uses pediatric data from the CALIPER RI (Canadian Laboratory Initiative on Pediatric Reference Intervals) study. The calculation of potential partitions is carried out using a regression tree model included in the rpart package of the statistical programming language R. The Harris & Boyd method is used to compare the corresponding partitions suggested by rpart and CALIPER. For better comparability, the reference ranges of the partitions of both approaches are then calculated using reflimR.

Results

Most of the partitions suggested by rpart or CALIPER show sufficient heterogeneity among themselves to justify age- and/or sex-specific RI partitioning. With only few individual exceptions, both methods yield comparable results. The partitions of both approaches for albumin and γ-glutamyltransferase are very similar to each other. For creatinine rpart suggests a slightly earlier distinction between the sexes. Alkaline phosphatase shows the most pronounced differences. In addition to a considerable earlier sex split, rpart suggests different age intervals for both sexes, resulting in three partitions for females and four partitions for males.

Conclusions

Our findings indicate that the automated analysis provided by rpart yields results that comparable to traditional methods. Nevertheless, the medical plausibility of the automatic suggestions needs to be validated by human experts.

L) to ascertain as effective drug for antituberculosis, anti-inflammatory, antioxidant, cytotoxic and antimicrobial activities. The organic ligand and its metal(II) complexes were characterized by numerous physical and spectroscopic methods, which showed that the complexes have a general formula, [ML], (where M = Co(II) (C1), Ni(II) (C2), Cu(II) (C3) and Cd(II) (C4)), for metal complexes have been proposed and have a square planar geometry, are amorphous in nature, and are thermally stable. Data highlight obtained from activity testing against tuberculosis, inflammation, and oxidants that all compounds are significantly active against these symptoms. Also, was to evaluate the effectiveness of various compounds against bacterial and fungal strains. Specifically, four bacterial strains (Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa) and two fungal strains (Aspergillus flavus and Candida albicans) were tested and compared to the results of some standard drugs. The results revealed that compound C4 was more effective against bacterial strains than the comparison standard drugs. In addition, C3 was found to be the most effective of the comparison antibiotics against fungi, while the other compounds showed moderate antifungal activity. Moreover, to support the vitro results, certain computational studies as molecular docking studies, DFT, MESP, and AMEDT were also conducted to confirm the effectiveness of an organic ligand and its complexes against tuberculosis. These studies revealed that C4 is the most effective against tuberculosis and has desirable effects such as absorption, no degradation and no hepatotoxicity, etc.
Labeling by type
Authors: Rouveret Alain
Published: August 2024

The primary goal of this article is to take advantage of some recent theoretical innovations in syntactic theorizing to propose a novel characterization of some of the basic word-order types isolated by typological research. In the minimalist framework, a necessary condition for a derivation to converge is that the structure it generates should be appropriately labeled. This requirement in particular holds for the major syntactic structures displayed by the various linguistic types. It will be argued that labeling theory, combined with phase theory and the variable syntax of inflectional and discourse features, offers contrasting characterizations of these structures and, as such, provides a window on how exactly SVO, V1 and V2 grammatical systems differ: they differ precisely in the strategy that each type selects in order for neutral declarative root clauses to satisfy the labeling requirement. It will also be shown that the topic and focus structures involving phrasal movement to the periphery, although different parametric choices are made by the various grammatical systems considered here, basically conform to the same requirement.

O trabalho aborda a temática da imposição do cristianismo nos Andes a partir da perspectiva da adaptação/reelaboração dos significados transladados, analisando os caminhos através dos quais se buscou estabelecer espaços comuns produzindo um redirecionamento da memoria que facilitava a introdução de elementos cristãos na vida religiosa, cujas ações se inseriam em estratégias comunicacionais que partiam da consideração sobre o Outro de acordo com as teorias cognitivas agostinianas e tomistas atualizadas na reflexão e trabalho educativo dos jesuítas, bem como na busca de uma língua universal que permitisse a comunicação entre culturas distantes. Estas buscas se materializaram na formulação de uma narrativa de conteúdos histórico-teológicos articulada com as concepções e mitos andinos, no emprego de símbolos locais na ornamentação das igrejas, na utilização de linguagens plásticas apoiado em formas americanas e no uso de concepções espaciais de implantação dos templos, em um verdadeiro processo de tradução dos elementos europeus para formas admissíveis e compreensíveis pelos habitantes dos Andes.

Aspectos Histórico-Legais das Rinhas de Galo na Paraíba: uma Prática Cultural e Problema Sócio-Ambiental
Authors: Aguiar José Otávio , Escobar Marco Lunardi
Published: August 2024

Historicamente, as rinhas de galo são realizadas com ou sem autorizações legais. O trabalho analisa a prática em comunidades da Paraíba. Trata-se de um conflito entre os princípios ambientais e a liberdade de manifestação cultural que existe em relação às rinhas de galo. Verifica-se que estas práticas submetem os animais à crueldade e devem ser combatidas pelo Estado brasileiro. Analisa-se, neste relato de pesquisa, a questão cultural da realização em comunidades da Paraíba. Entendimentos do judiciário da Paraíba inibiam as fiscalizações e consideravam a briga das aves uma manifestação cultural. Porém discorda-se deste posicionamento, pois defende-se, neste trabalho, que é obrigação do estado tutelar a fauna, pois no Brasil os animais domésticos e silvestres constitucionalmente devem ser protegidos contra os maus-tratos. O patrimônio que se defende é a fauna brasileira, portanto não se pode falar em preservação do patrimônio cultural como argumento para se permitir a realização de rinhas de galo.

Driving economic inclusion: Analyzing the participation of individuals with disabilities
Authors: Malecka Joanna , Czerkawski Dominik , Duhacek Sebestova Jarmila
Published: August 2024

The population with disabilities constitutes the largest minority group in the labour market, facing social and organizational barriers. The ambiguous nature of employment support provisions and the lack of unified vocational activation systems hinder their economic participation. This study reviews existing literature and examines the effectiveness of support programmes, and discusses the employment challenges faced by disabled individuals. The research emphasizes the need for coordinated national guidelines and highlights disparities across Central and Eastern European countries. The objective of this study was to analyze the economic activity of individuals with disabilities in micro, small, medium, and large enterprises in Poland. The study was conducted using the CAWI method (computer assisted web interview). The questionnaires were sent and completed online. The study found that individuals with severe disabilities may face greater challenges in accessing resources to support their own sole proprietorship (8.33%) in the labour market, compared to entrepreneurs with moderate (66.67%) and light (25%) disabilities. Furthermore, only 2.56% of individuals with physical disabilities are employed in micro-enterprises, with 32.08% being professionally inactive. This study identifies significant factors that contribute to the active participation of disabled individuals in the workforce, particularly in the Wielkopolska region, which was chosen as a case study. The results of the survey indicate a preference for enterprises without a high proportion of disabled employees. The factors influencing disabled individuals’ participation in the workforce include age, education, and professional activity. The improvement of the system should take into account company size, disability level, job assessment tools, and the use of job coaches. Incentives should not be based on disability status. The findings from this study have the capacity to inform about changes in SME job creation and enhance professional activity for people with disabilities.
Information and communication technology diffusion, supply chain performance, health care and human development: A case of the South Asian region
Authors: Akbar Minhas , Hussain Ammar , Nazir Marina , Poulova Petra , Huang Jiashun
Published: August 2024

South Asian countries have shown tremendous progress in information and communication technology (ICT) and have become one of the fastest-growing regions in technology, innovation, and business competitiveness. The pivotal role of ICT diffusion in the economic growth of both developed and developing countries is a well-established fact. Therefore, this research aims to examine the impact of ICT diffusion (especially the evaluation of ICT indicators) on three core outcomes, namely supply chain performance, health-care expenditures, and the Human Development Index in the context of South Asian economies. To measure ICT, we used three core ICT indicators (i.e., fixed broadband subscriptions, mobile phone subscribers, and internet users) individually as well as in the form of an index developed through principal component analysis (PCA). Panel data of South Asian economies ranging from 2007 to 2021 were used to estimate the equations. The outcomes revealed that all the variables were integrated at order one (1). Second, ICT had a long-run/equilibrium relationship with supply chain performance, health-care expenditures, and human development index. Third, the response of all individual ICT indicators as well as the ICT index on supply chain performance was positive and significant in estimated coefficients. Fourth, the ICT index and all ICT indicators had a positive influence on health-care expenditures. Finally, the ICT index and two out of three individual ICT indicators had a positive and significant influence on HDI. Interestingly, among all the three indicators of ICT, internet users were found to have more pronounced effects on the promotion of supply chain performance, health-care expenditure, and HDI. The more pronounced effect of internet users implied that policymakers should consider devising policies to promote ICT penetration with a core focus on internet penetration.
EFFECT OF COMMERCIAL WATER REPELLENT AGENTS ON FUNCTIONAL PROPERTIES OF POLYESTER WOVEN FABRIC USED FOR WASHABLE MEDICAL MASKS
Authors: Tho Luu Thi , Phuong Duong Thi , Huong Chu Dieu
Published: August 2024

Water repellent fabrics are always used for washable medical mask production to keep them from the bacterial liquid during use. Choosing the right water repellent which is efficient and suitable for fabric is important in washable medical mask production. The water-resistant treated fabric needs to keep its water repellent for many washed cycles. Moreover, their physico-mechanical properties such as air permeability and thickness must be less changed. In this study, four commercial water-resistant chemicals (Ruco–Coat BC 7068, TP – Phob FC 2904, Phobotex RHP Hydrophobic Agent, Ruco-guard AFB60) were used to treat the 100% polyester woven fabric to examine the influence of the type and concentration of the waterresistant chemicals on water repellent capability of the polyester woven fabric. The fabric thickness and the air permeability of the untreated and treated fabric were investigated. The SEM, FE-SEM analysis, and the FTIR spectra were used to find the differences between the initial and treated fabric. The results showed that the water-resistant type influenced the water repellent capability of fabrics and their duration. Among four investigated water resistance, the TP – Phob FC 2904 presented the best water resistance for treatment of the 100% polyester woven fabric, and its concentration of 50 g/l has maintained 85 % fabric water repellent capability after 25 washed cycles.

This study compares the airflow resistivity and acoustic properties of fibre-reinforced plastic composites (NFRP) with different mixing ratios of polylactic acid (PLA) and the natural fibres flax and cotton for the application in construction as lightweight structures, car door linings or seat pans. The composites are made from the binder fibre PLA, the bast fibre flax and two different kinds of cotton. Nonwovens are consolidated with a thermoforming process to manufacture the NFRP. The addition of cotton improves the absorption by increasing the number of air pockets (pores) and reducing their shape due to the fineness of the cotton. The airflow resistivity of samples with different mixing ratios were analysed and compared. The airflow resistivity is modelled with different calculation models that use distinct material parameters and the transferability is assessed. Further, the absorption coefficient is analysed and compared to the airflow resistivity. The study shows that there is a dependency of the two parameters.

Kabwe, Zambia, is known in the global health world for its high concentrations of environmental lead and associated high blood lead levels in children, and thus it is a key region for exploring the intersections of human health and well-being (United Nations Sustainable Development Goal, SGD #3) and environmental health (SGD #12 and #15). Despite multiple efforts to remediate lead from the landscape, lead contamination remains pervasive in some Kabwe neighborhoods. Our study examined to what extent lead remediation was also a priority for community members. Using open-ended oral surveys with 49 household heads as well as ethnographic observational notes, we found that while lead is a concern, it is just one of many concerns. Indeed, economic concerns outweighed other concerns (SGD #1 and #6). Because community buy-in is vital to any global health intervention, these results suggest that externally defined intervention goals, such as lead remediation to address environmental toxicity, may be more successful if interventions also incorporate locally salient concerns. We conclude by arguing that social scientific studies of community members’ perspectives and concerns should be prerequisite to global health interventions. In the context of Kabwe, intervention efforts that incorporate solutions to address local concerns about poverty (SDG #1) and economic opportunity (SDG #6) may result in improved community cooperation with environmental remediation efforts, and thereby improved likelihood of sustainable environmental remediation.

DFT calculation is used to investigate the structural, electronic, optical, and elastic properties of AgCuSe and AgCuS. The calculations are performed using the ATK with generalized gradient approximation (GGA) in combination with Hubbard U correction parameters for both structures. The calculated band gap energies and partial density of state reveal that AgCuS has semiconductor properties unlike this AgCuSe has a metallic nature. The optical properties, real and imaginary parts of dielectric function are obtained for the energy range of 0 to 5 eV. Elastic stiffness coefficients (Cij), bulk modulus (B), shear modulus (G), and Young modulus (E) have been calculated.

With society's rapid progress, there is an increasing need for electricity among individuals, but the prevailing source of electricity is still mainly obtained through the burning of nonrenewable fossil fuels, which are not renewable and pose serious environmental hazards. Lithium-ion batteries are used widely for excellent rechargeable capabilities and high energy density. Recently, researchers have become increasingly interested in transition metal sulfides owing to their cost-effectiveness and remarkable specific capacity. However, their commercialization has been hindered by the expansion of material volume and low electrical conductivity during charging and discharging. We have successfully designed and synthesized MoS2 nanosheets loaded on carbon spheres with a 3D hollow structure starting from SiO2 as a template. Due to the doping of carbon materials and particular 3D hollow structures, the optimal C/MoS2-0.3 hollow nanocomposites exhibit excellent electrochemical performance. Following exposure to over 900 cycles at a 0.5 A g-1 ampere density, the materials exhibited an exceptional 958.50 mAh g-1 reversible capacity, demonstrating their remarkable performance.

A new type of Ag2S-CdS/Ag/GNP nanocomposite material was successfully synthesized in the presented work. The structural and physical properties of compounds were studied separately and together. Ag2S-CdS/Ag/GNP nanocomposite materials were studied by Xray diffraction (XRD), Ultraviolet-Visible (UV-Vis), Fourier Transform Infrared (FTIR), Raman spectroscopy and Scanning Electron Microscopy (SEM). Based on the results, Ag nanowires (NWs) were successfully synthesized, and then it was determined that during the hybridization process, two phases of acanthite Ag2S and the cubic crystal system of Ag2O were formed. Then, Ag2S-CdS NWs were formed from mixed monoclinic Ag2S and hexagonal CdS. In the absorption spectrum of Ag NWs, the main absorbance peaks were observed at 357.3 nm and 380.2 nm. The energy gap (Eg) values of the Ag sample are 3.8 eV. The band gap value of Ag2S (2.5, 3.8, 4.6 eV) and Ag2S-CdS (2.5, 3.8, 4.8 eV) have a triple value due to the formation of a hybrid structure. The Raman spectrum of Ag2S-CdS belongs to longitudinal-optical (LO) phonon modes of zinc-blende phase CdS and for the 1, 2, and 3 times spin-coated samples on the surface of GNP/PVA have observed all characteristic Raman peaks, which belong to NWs at 485.13 cm-1, and 960.22 cm-1.

In this study, we used Raman spectroscopy to compare the local structure of Ge2Sb2Te5 (GST) thin films with thicknesses of 90 nm and 271 nm that were crystallized through thermal annealing and laser radiation (laser annealing) during the recording of Raman spectra in situ. We found that for all crystallized films, the position of the main peaks in the Raman spectra was almost the same, and their structure corresponded to a hexagonal close packed state. It is noteworthy that the full width at half maximum (FWHM) of the main peaks varies considerably depending on the crystallization method used.

As eco-friendly corrosion inhibitors, antioxidants, and antibacterial agents, this study assesses 1,3-bis(2-hydroxybenzylidene) thiourea (B1) and 1,3-bis(2-hydroxybenzylidene) urea (B2), two new Schiff bases, on their performance in these areas. We successfully synthesized these Schiff bases in just 15 minutes using an environmentally friendly approach, and the yield was rather good, ranging from 69.8% to 87.53%. When compared to B2, B1 showed more effective corrosion inhibition and better antioxidant activity. Both chemicals were highly effective against microbes, while B1 was particularly effective against Aspergillus. B. We measured the weight loss to examine the corrosion inhibition impact of XC48 carbon steel in 1M HCl. The findings revealed that at the ideal concentration of 5.10–4 M, the estimated IE% of the Schiff bases was 63.8% for B2 and 87.28% for B1. This study employed the Langmuir isotherm model to determine a number of thermodynamic and kinetic characteristics, all of which pointed to a physical adsorbed state. Promising electrical characteristics and robust adsorption on metal surfaces for B1 were corroborated by theoretical investigations employing density functional theory (DFT) and molecular dynamics (MD) simulations. Both the theoretical and practical aspects align with one another.
