La enseñanza Normal en Yucatán durante el Porfiriato y las fuentes para la escritura de su historia
Authors: Muñoz Vega Alicia
Published: January 2025

El siglo xix es un periodo importante en la historia de México desde el punto de vista educativo, pues fue durante ese tiempo cuando surgieron las ideas en torno a una enseñanza obligatoria, gratuita y laica que se consolidaron en el Porfiriato (1976-1911). La instrucción pública recibió más atención por parte del gobierno federal y las escuelas dedicadas a la formación de maestros experimentaron un auge en cuanto a su fundación a lo largo del territorio mexicano. Sin embargo, aún existen regiones en las que es necesario investigar este tema debido a sus escasos trabajos. Tal es el caso del sureste mexicano, y en particular de Yucatán. El propósito de este escrito es presentar un panorama general acerca de la enseñanza Normal en Yucatán durante el Porfiriato y las fuentes de información para su estudio. Asimismo se busca analizar los aportes de dichos documentos y dificultades para su consulta. Para ello estructuro este trabajo de la siguiente manera: el primer apartado está dedicado a una breve introducción acerca del surgimiento de la historiografía mexicana y la historia de la educación, seguido de los trabajos que se han hecho del normalismo en México; posteriormente me refiero a las indagaciones de historia de la educación a nivel regional –el caso de Yucatán–; en una tercera parte menciono las fuentes primarias y secundarias accesibles de esta temática, y por último mis reflexiones finales.

Agonists Targeting the cGAS-STING Signaling Pathway and Their Applications in Cancer Therapy
Authors: Lin Shilan
Published: January 2025

The cyclic GMP-AMP synthase (cGAS) serves as a pivotal component of the immune system, playing a crucial role in regulating the innate immune response elicited by both exogenous and endogenous DNA. This enzyme recognizes the aberrant presence of DNA in the cytoplasm, subsequently activating the signaling pathway mediated by the stimulator of interferon genes (STING) and thereby fulfilling a critical role in immune response mechanisms. This review delineates the mechanisms of the cGAS-STING pathway and elucidates the small-molecule agonists targeting STING, along with their combined applications in various tumor treatment strategies. The aim of this review is to provide a valuable reference framework and insights for ongoing research in related fields.
Hybrid Compound Formation in Classical Papiamentu
Authors: De Araujo Gabriel Antunes , Mendes Guilherme
Published: January 2025

Since its genesis, Papiamentu has been influenced by several lexifiers. This study examines etymological patterns of hybrid formation in Classical Papiamentu (CP), mainly focusing on Iberian and Dutch contributions. Studying morphosyntactic functions in hybrid words can reveal typological relations between Creole languages. Thus, this study aims to expand linguistic knowledge about CP and Creole languages in general. The corpus contains sixty-one hybrid compound words from CP, mostly compound nouns and compound verbs, compiled from the Woordenlijst, the first Papiamentu vocabulary, printed in 1859. The process of classifying hybrid words is described, and examples are provided. Hybrid etymological patterns are quantified in both anterior and posterior positions. The frequency of etymological patterns is displayed in separate tables for nouns and verbs. The data analysis focuses on morphosyntactic relations between internal components based on etymological occurrences. The compounding syntax of CP is the basis for arguing in favor of a more significant Iberian influence over word formation in CP. Data analysis reveals that Iberian syntactic structures are replicated in hybrid formations even when both components are Dutch loans. The overall prevalence of Iberian lexicon occupying the head position in both compound nouns and compound verbs supports this argument. The results also show a preference for syntactic phrases to link components within a compound.

The integration of extensive reading strategies and innovative technologies has become a vital component of English as a Foreign Language (EFL) education. While extensive reading (ER) fosters learner autonomy and vocabulary acquisition by promoting engagement with diverse reading materials, the incorporation of digital tools—such as e-books, online platforms, and mobile applications—has further enhanced accessibility and interactivity. However, gaps remain in the understanding of how these elements interact and which configurations yield optimal outcomes for learners, especially in terms of fostering self-directed learning and vocabulary growth. This research addresses these gaps by employing fuzzy-set Qualitative Comparative Analysis (fsQCA) to examine the interplay between extensive reading, metacognitive strategies, and technological tools. Data were collected from 130 EFL learners through pre- and post-tests, questionnaires assessing learner autonomy, and classroom observations. Results reveal three effective pathways to learner autonomy and vocabulary acquisition: (1) comprehensive integration of extensive reading, technology, and metacognitive strategies; (2) focus on traditional reading and metacognitive strategies without technology; and (3) technology and metacognitive strategies without extensive reading. Extensive reading was found to be the most impactful strategy, achieving the highest correlation with autonomy and vocabulary acquisition. The study concludes that a balanced approach, combining extensive reading, metacognitive strategies and selective use of technology, offers the most effective framework for fostering EFL learners' autonomy and vocabulary development. These findings provide valuable insights for educators and policymakers when designing language-learning programs tailored to diverse learner needs while ensuring the strategic use of both traditional and digital methodologies.

Authors: Vishal Murlidhar Girbane  , Rasika Ramchandra Kedari  , Rushikesh Achut Munde
Published: January 2025

This study explores the molecular docking and ADMET properties of bioactive compounds from Phyllanthus niruri and captopril in relation to ACE inhibition for managing hypertension. The five natural compounds, including rutin, gallocatechin, quercitrin, astragalin, and kaempferol, were evaluated for their binding affinities through docking analysis. The results demonstrated that these compounds exhibit strong binding energies, with rutin showing the highest affinity (-9.8 kcal/mol) compared to captopril (-5.5 kcal/mol). ADMET profiling revealed that the natural compounds, particularly rutin and kaempferol, possess favorable pharmacokinetic properties, including high GI absorption and low toxicity. Additionally, while captopril exhibited high protein binding and moderate clearance, the natural compounds presented lower toxicity across various parameters, such as hepatotoxicity and genotoxicity. Overall, these findings suggest that Phyllanthus niruri compounds could serve as promising natural alternatives to captopril for ACE inhibition, offering an improved safety profile and favorable drug-likeness properties.

Published: January 2025

This manuscript introduces a novel methodology for detecting anomalies in iron structures using synthetic data and machine learning algorithms. Synthetic datasets representing normal and anomalous conditions were generated through simulated gamma-ray interactions with iron. Decision tree and support vector machine (SVM)-based classifiers were employed to train a model capable of distinguishing between intact and defective materials. This data-driven approach provides a scalable and efficient platform for non-destructive testing across industries such as construction, transportation, and manufacturing.

In the future, we plan to integrate IoT devices into this framework to enhance its practical applicability. The manuscript presents the design and proposed methodology for machine learning-based anomaly detection in iron structures using synthetic data.
The health risks associated with long-term fuel exposure on Saudi Arabian workers: Prevention strategies and best practices
Authors: Idriss Bakar M. Al-Barnawi
Published: January 2025

Clinically, petroleum products contain harmful chemicals. The health impacts of fuel pollution have become a real environmental problem in Saudi Arabia, which largely rely on the petroleum industries. The aim of this review paper is to highlight the health risk associated with long-term exposure to fuel pollutions on the workers of Saudi Arabia, and to elaborate the prevention and protection strategies for safety practices. The review showed how the workers in Saudi Arabia (as a leading oil producer country) exposed to fuel during their work in its volatile form (volatile organic compound; VOC). This air pollution can cause adverse effect on their health (e.g., hematological disorders) as was reported in many places within Saudi Arabia. The review also reflected the needs for evaluation parameters to assess the level of exposure to these contaminants. Also, recent evidence was introduced about acute and long-term exposure to VOCs was introduced. The systemic health implications, included respiratory, immunological, hematological, dermatological, renal, reproductive, and central nervous system pathologies.

House price prediction with Convolutional Neural Network (CNN)
Authors: Mohit Jain  , Arjun Srihari
Published: January 2025

In this paper, we examine the applicability of Convolutional Neural Networks (CNNs) for predicting the cost of houses with an inclusion of visual and non-visual elements. Traditional end-to-end patterns of supervised machine learning usually incorporate a finite set of numerical or categorical features, ignoring spatial and aesthetic information. CNNs, which can parse complex patterns in unstructured data, represent a way to improve predictive accuracy at the price of including property images with numerical and geographical coordinates. This variety of inputs is integrated within the proposed model to reflect the visual and contextual aspects of real estate valuation. The training and testing set used property images, georeferenced information, and typical numerical features. Incorporation of architectural features, including design, quality and neighbourhood aesthetics, showed a higher variance than the baseline machine learning model. Analysis of the outcomes obtained in experiments showed that CNN-based models performed better than the benchmark models, such as regression, gradient boosting, and random forest regression, in identifying the subtle interconnection between attractiveness and property values. The results further support the ability of CNNs to use multimodal information to solve diverse prediction problems within real estate. This research emphasizes the potential value of disseminating multiple data sources and merging relatively sophisticated neural structures into real estate applications, indicating the future viability of such paradigms in broader property market technologies. Subsequent studies can look at topics such as increasing the capacity of model structures and expanding the dataset to incorporate time dependency and other regions.

The antimicrobial as well as the larvicidal activities of n-hexane root extract of Ixoria coccinea against Aedes aegypti was evaluated in this work. The extraction was done using maceration method. Agar well diffusion method was used to assess the antimicrobial activity of the extract against different clinical isolates of gram positive and gram-negative bacteria. The larvicidal activity was evaluated according to World Health Organization (WHO) guideline for larvicidal assay as follow: a stock solution of 10mg/ml was prepared for each extract from which five different concentrations (1.0, 2.0, 3.0, 4.0 and 5mg/ml in 100ml) were made and used for the test. A control was also prepared for each extract. A total of 20 larvae were used for each of the concentration and mortality was recorded at 24, 48 and 72 hours. The result of the antimicrobial assay showed that at 100mg/ml concentration, the extract gave an inhibition zone diameter of 17±1.41mm for Staphylococcus aureus, 8±0.82mm for Bacillus spp, 2±0.00mm for Stapylococcus epidermidis, 4±0.58mm for Pseudomonas aeruginosa and 6±1.29mm for Escherichia coli. The extract was most active against Staphylococcus aureus with an MIC of 50mg/ml. The extract is not active against all the fungi species used in the test. Examination of the result for larvicidal assay against Aedes aegypti larvae showed that the LC50 after 24, 48 and 72 hours are 1.782, 1.376 and 0.686mg/ml respectively. At concentration of 3mg/ml there was 100% mortality after 72 hours. The results showed that the n-hexane root could serve as a source of both antibiotic and mosquito larvicides

Published: January 2025

The article presents the results of studying the biological characteristics (antagonistic and cellulase activity, antibiotic resistance, indolyl-3-acetic acid (IAC) production, the presence of polyketide synthase and cellulase genes) of 13 bacterial strains of the genus Streptomyces. The screening revealed a strain of Streptomyces sp. 2K10 with a high level of antifungal activity against the pathogen Fusarium petroliferatum; three strains (RPLN23, 1N8, 3N2) – antagonist of the causative agent of wheat septoria nodorum blotch (Parastagonospora nodorum). As a biocontrol agent of phytopathogens, the most promising strain among the studied streptomycetes is RPLN23, characterized by antifungal activity (diameter of inhibition zones 24–30 mm), the presence of PKS II genes (229 bp) and the ability to synthesize IAA. For biocontrol of bacterial and fungal pathogens, it is proposed to use the strain Streptomyces sp. 3N3. The work also revealed strains capable of effective destruction of carboxymethylcellulose (RPLN12, 2K9 and 3K9), and strains with genes encoding cellulases of the GH74 family (RSFN5, RPLN12, 3N2) in the genome. A number of streptomyces (RSFN5, RPLN5), which did not show antagonism to the studied cultures of fungi and bacteria, are at the same time interesting for the presence of the PKS II and GH74 genes. Most of the streptomyces studied in the work are sensitive to antibiotics of various groups: aminoglycosides, tetracycline, polypetides, chloramphenicols ansamycins and macrolides, but not β-lactams. The obtained data contribute to the disclosure of the potential of streptomyces for their practical use.

Published: January 2025

The hidden depleting degradation of the effective fertility of previously cultivated agrarian sod-podzolic soils is one of the most significant risks for the development of agriculture in the Non-Chernozem region and its food security. In a stationary long-term experiment, established in the Leningrad region in 2006, a comprehensive assessment of the effectiveness of accelerated cultivation of degraded sandy loam agrarian sod-podzolic soil to a good and high level of cultivation was performed. The objects of the research were three types of soil (medium-, well- and highly cultivated) and crops of cereal and row six-field crop rotations, cultivated in a three-variant scheme of a complete mineral fertilizer system. During the study in the second rotation of crop rotations (2012–2016), it has been established that the responsiveness of crops to accelerated soil cultivation and complete mineral fertilizer is determined by a combination of their biological and varietal characteristics with weather, climatic and phytosanitary conditions. The average annual productivity level of studied crop rotations on medium-cultivated soil amounted to 3.9 and 3.8 thousand grain units per ha. On well–cultivated and highly cultivated soil the productivity increased by 34 and 67, 50 and 86 %, respectively, and from the use of a complete mineral fertilizer system – by 28 and 18 %, respectively. The level of profitability of soil cultivation varied from 51–97 % in the crop rotation with cereals, and to 234–301 % in the row crop rotation with an average annual net yield of 12.1–13.1 and 97.1–110.4 thousand rubles/ha. The payback period for accelerated cultivation to a good and high level was 3.3 and 5.1 years in the crop rotation with cereals and 0.6 and 1.2 years in the row crop rotation, respectively.

Published: January 2025

Increasing the production of high quality ecologically pure animal products, especially beef is one of the main tasks of the agro-industrial complex. In this regard, it is necessary to apply measures for the effective use of genetic resources of both domestic and imported origin, improving feeding systems, using feed additives, biological active substances that stimulate the growth and development of animals. The aim of the study was to determine the effect of the feed additives Plexomin Zn 26 and Plexomin Se 2000, containing in its composition zinc and selenium in organic form, on the slaughter parameters of Black-andWhite bulls, as well as on the quality of the obtained product - beef. For the research, 15-month-old Black-and-White bulls were divided into two groups (control and experimental) of 20 heads each, average live weight was 328.8–329.3 kg. The experiment lasted 91 days. The difference was that the experimental animals were fed with the feed additives Plexomin Se 2000 at a dosage of 1.2 g/head/day and Plexomin Zn 26 at a dosage of 1.2 g/head/day as part of the concentrated part of the diet during the study period. A control slaughter was carried out at the meat processing plant "Orenbeef" for comparative evaluation of meat productivity and beef quality of bulls fattened with and without feed additive. As a result of the research, it was found out that experimental bulls outperformed their control counterparts in live weight at the end of the experiment by 2.5 % (Р≤0.05), pre-slaughter live weight by 2.2 % (Р≤0.05), fresh carcass weight by 4.5 % (Р≤0.01), internal fat weight by 22.1 % (Р≤0.05), slaughter weight by 5.2 % (Р≤0.01), and slaughter yield by 1.62 % (Р≤0.05). Meat from experimental bulls contained 1.35 % more dry matter (Р≤0.05), 0.26 % more fat (Р≤0.05), 32.9 % more glycogen (Р≤0.01), 1.3 % less moisture (Р≤0.05), 7.1 % more oxyproline (Р≤0.05) and 1.92 % more pH (Р≤0.05).
The effect of the in ovo injections of dextrin and L-carnitine in conditions of thermal stress during the incubation period on the embryonic development and growth of broiler chickens

Published: January 2025

The embryonic thermal stress due to the overheating is a common problem of the incubation of broiler eggs and hence the search for the methods of metabolic corrections of the related shifts in the embryonic development can be practically actual task. The aim of the research was to study the effect of the in ovo injections of heat stressed chicken embryos with the combination of dextrin (as glucose source) and L-carnitine on the efficiency of incubation and early postnatal growth rate. The study was performed in 2020 on incubated eggs, embryos and chicken of Cobb-500 final hybrid cross. Three groups of eggs (n = 62) were formed for each temperature regime of incubation: without injections, physiological saline injection, injections with the solutions of dextrin (10%) and L-carnitine (0.6%). The eggs were injected with physiological saline, the solutions of dextrin and L-carnitine at the 17th day of incubation. Then the incubation was carried out in hatchers at normal temperature (37.2 °С) and increased temperature (38.5–39.0 °С). The increased temperature during hatching period on average among the groups decreased the hatchability of eggs by 6.1 % and relative weight of chicken by 0.96 %. The injection in ovo with the mixture of dextrin and L-carnitine 1.6–3.2 % increased the hatchability of eggs incubated at increased and normal temperature, respectively. The live weight of day-old chicks injected in ovo with the solution of dextrin and L-carnitine at normal temperature was significantly higher by 1.3–2.3 % (p <0.05) as compared with control groups. Neonatal growth rate was higher in chicken injected in embryonic period with dextrin and L-carnitine both at normal and increased temperature – live weight of 7-day chicken of the experimental groups was 5.9 and 5.1 % higher (p <0.05) compared with the control groups of the same temperature regime. In chicken incubated at increased temperature the differences remained to 35 days of age and were 5.7 % (р <0.05). Biochemical variations were noted in blood parameters of embryos of the control and experimental groups that proved the absorption of exogene nutrients and biologically active substances by the embryo. Thus, in blood plasma of 17-day embryos injected in ovo with the solution of dextrin and L-carnitine the concentrations of glucose significantly increased by 1.6-1.7 % (p< 0.001) and triglycerides by 46.2 % (p <0.05). So, by injecting the incubated eggs during hatching period with the solution of dextrin and L-carnitine, the neonatal growth rate of chicken raised at normal and increased temperature and during heat stress as well. No significant effect of the injection on the hatchability of eggs in conditions of thermal stress in the hatching period was found.

Published: January 2025

La búsqueda de prácticas de enseñanza genuinas mediadas por la tecnología digital es una necesidad dentro del ámbito universitario. En base a ello, esta investigación tiene como objetivo principal analizar la docencia universitaria emergente en la búsqueda de nuevos replanteamientos. A fin de alcanzarlo, se ha realizado una revisión sistémica de la literatura pertinente en las bases de datos Web of Science y Scopus. Se ha iniciado con 147 investigaciones y, tras diferentes fases de filtrado y cribado, se han estudiado en profundidad 35 artículos. Los resultados indican que existen diversidad de prácticas de enseñanza vinculadas a las metodologías activas, aunque estas no suelen estar relacionadas con un uso amplificado o de carácter innovador en la praxis docente. Además, se expone como el COVID supuso un estímulo en la incorporación de estas prácticas, no suponiendo un cambio radical o transformador a posteriori. Finalmente, como conclusión principal, hay que destacar como las prácticas emergentes mediadas por la tecnología digital requieren de una mayor formación docente, una visión de estas menos instrumental y una reconfiguración de ellas con la vista puesta en un nuevo horizonte.

Parts wear process always associates with the operation of machines and mechanisms. An important task is to minimize friction energy losses, and it is lubricants that are used for that, which, in turn, can contain various dispersed components. These components are divided into three groups: being formed during the friction process, some entering friction units from the outside and others, being purposefully added. The paper studies in detail the influence of such dispersed components as microorganisms (microscopic mold fungi) and purposefully added fillers, in particular, serpentinite, on the processes of friction and wear. The conditions of occurrence and mechanism of biological damage, as well as toxins released by microorganisms are viewed. The structure and principle of action of serpentinite are given. To perform the tests, four different brands of greases were used (Lita, TSIATIM-201, GOI-54p and MS-70), as well as samples of lubricants with mycotic molds lesion in Petri dishes and fine serpentinite powder. Tribological tests were carried out on a Bosch PBD-40 machine, and the diameters of wear spots of the balls located in the friction unit were measured using a DigiMicro 2.0 digital microscope. As a result of conducted tests, it was found that in case of using greases with mold fungi in the friction unit, deterioration of tribotechnical characteristics such as average friction force and mean diameter of the wear spot was most often observed as compared to basic lubricants. And when using a lubricant composition consisting of contaminated lubricant and serpenitinite, there has always been an improvement in these tribotechnical indicators as compared to contaminated greases without serpentinite, so it proves the effectiveness of filler addition.

The era of disruption that occurred globally had affected all human life in various fields, both  in the economic, social, cultural, political, educational and other fields. Pancasila as the basis of the  state and as the nation's view of life, must not be abandoned in order to achieve the values of the  precepts contained in Pancasila. Pancasila holds an important role to be a filter of new values by  applying the values of Pancasila in all aspects of life. The research method used in this article is  qualitative research and library research method. The industry 4.0 with all the disruptions that  follow needs to be addressed critically by living the values as one of the foundations that are  maintained in the disruption of the industry 4.0.

Published: January 2025

The book presents articles by eighteen scholars from Russia, Bulgaria, North Macedonia, and Serbia, dedicated to the Balkan Wars of 1912–1913. The works cover not only the conflict itself but also its preparation, conclusion, influence on modernization processes on the peninsula, and the historical memory of the Balkan peoples. The military and diplomatic aspects of these events are presented, along with perspectives from abroad — the Russian, German, Slovenian, and Czech societies. The work is intended for specialists, university professors, as well as anyone interested in international relations in the Balkans and Europe, and the Slavic idea on the eve of World War I.
Climate Risks and Migration Intentions
Authors: Pardos-Prado Sergi , Bayer Patrick , Öztürk Aykut
Published: January 2025

Is climate change a significant driver of individual migration intentions? We contribute to this debate by: 1) offering a causal inference perspective on a decision typically influenced by numerous unobserved factors, 2) distinguishing between climate as a push and pull factor, and 3) testing the role of labor market transferability as a constraint on climate-induced migration. Using priming and choice-based conjoint experiments in Nigeria, our findings reveal limited average effects of climate risks on international migration, challenging some of the most apocalyptic forecasts of climate-induced displacement. However, personal exposure to sudden events like floods significantly increases international migration among those working in agriculture. Floods also have modest but broader effects on regional migration within Nigeria, particularly for individuals with limited labor market options. Climate considerations substantially influence destination choices as pull factors, but economic and political motivations remain stronger.
Learning and Teaching with AI in STEM Education: An Umbrella Review
Authors: Zhang Shan , Jaldi Chris Davis , Schroeder Noah L
Published: January 2025

Artificial intelligence (AI) is increasingly integrated into educational settings, particularly within Science, Technology, Engineering, and Mathematics (STEM) education. However, existing research syntheses on AI in STEM are fragmented, each focusing on different subjects, leaving a lack of comprehensive understanding. To address this, we conducted a systematic review of systematic reviews, also known as an umbrella review. We identified and analyzed 13 reviews focusing on AI in STEM education covering Science, Computer Science, Mathematics, and broader STEM fields. We analyzed key implications for research and practice, research gaps, and future directions in each field, and used a wide range of quality metrics to assess trends. Our results reveal that most research focused on the development of effective AI systems, with less emphasis on their integration and practical implications. Consequently, there is a need for more rigorous and longitudinal studies to substantiate key research findings in the field. Implications for research and practice are discussed.

Published: January 2025

Speech production displays characteristics of rhythm, including the hierarchical and nested sequencing of smaller elements, such as phonemes and syllables. Recent findings have revealed associations between deficits in rhythm and several neurodevelopmental and speech-language disorders. A better understanding of speech rhythm, including how speech rhythm may change across the school-age years and between the sexes may shed light on potential clinical markers of speech rhythm for the potential identification of speech-language disorders in children. Given the current lack of knowledge pertaining to age related changes in speech rhythm, in this study we used two different quantitative approaches to measure speech rhythm across the school-aged years with a particular focus on potential differences in speech rhythm between males and females. Speech rhythm was quantified using interval metrics, which measure the duration and variability of vocalic and consonantal utterances, as well as spectral metrics, which conceptualize rhythm as periodicity in the speech envelope. Protracted changes in numerous interval metrics and spectral metrics suggest that the speech of children generally becomes more rhythmic during the school-age years, particularly at the rate of syllable production.

Picobirnaviruses (PBVs) are double-stranded RNA viruses found in a wide range of hosts including humans, animals, invertebrates and birds. First discovered in 1988 from a human stool sample, PBVs were initially considered human pathogens associated with gastrointestinal illness. However, PBV has not been definitively linked to any specific disease. The nature of their pathogenicity remains unclear, raising questions as to whether PBVs are true pathogens, opportunistic pathogens or merely bystanders. The PBV genome contains extremely high levels of genetic diversity within and between sequences, as well as in the genetic codes used for translation, leading to speculation that the virus may be prokaryotic. Several methods are currently used to detect and characterise PBV genomes. In this review, we summarise the contemporary methods used to attempt host identification, highlighting the current challenges of the methods. The methods include direct culturing, PCR, next-generation metagenomics sequencing, and cloning into bacteria. Uncovering the host could elucidate PBVs' role in both human and animal health and the broader implications within various important ecosystems.
