The current state and syntaxonomic structure of anthropogenic vegetation of the classes Galio-Urticetea and Bidentetea are revealed. The class Galio-Urticetea is represented by 3 phytosociological orders, 6 alliances, and 32 associations. The class Bidentetea unites 8 plant associations of 1 order and 2 alliances. The territorial differentiation of the studied plant communities is caused by the limiting factors: soil moisture and the changing hydrological regime. Thus the phytocoenoses of these classes are confined to the natural zones of Polissia and forest-steppe. Based on detrended correspondence analysis, the leading factors differentiating vegetation units were identified. Within the class Galio-Urticetea, they include the continentality of climate, precipitation regime, and concentration of mineral nitrogen in the soil. The factors of major significance for Bidentetea were soil moisture and the concentration of mineral nitrogen in the substrate.
Taxonomic characterization, morphological variability, and geographic patterns of Juniperus turbinata Guss. in Algeria
Authors: Elmir Merouane , Beghami Yassine , Mazur Małgorzata
Published: May 2024

A biometric study of cones, seeds, needles, and branchlets was conducted in 15 natural populations of Juniperus turbinata Guss. within its Algerian range. Each population was represented by 20-30 individuals. A total of 386 individuals were examined to evaluate inter- and intraspecific variation, and its geographic patterns, confirming the status of J. turbinata in Algerian populations. Maritime and mainland (Atlas Mountains) populations differed significantly. Cones in the seaside areas tended to be longer and more turbinate, with fewer seeds (mean 4.80) and leaves on the terminal 5-mm section of lateral branchlets (mean 27.87), compared to those from the Atlas, with 5.75 seeds and 29.00 leaves on average. The Aurès Mountain populations had more leaves than other scale-like junipers and other species of the Cupressaceae. Furthermore, maritime popula­tions stood out for having the most turbinated cones among recorded Juniperus phoenicea s.l. populations. Costal populations were more related to those located on oriental Mediterranean shores, while Atlas Mountain populations seemed to be related to Moroccan Atlas ones. A negative gradient of leaf number from east to west was identified in the Atlas group, extending into Morocco. The distinct separation between the 2 geographic patterns supports the hypothesis of migration of J. turbinata along 2 routes and relaunches the proposal of possible varieties within the group.
Rosyjska tożsamość – pro et contra
Authors: Dobieszewski Janusz
Published: May 2024

В статье рассматривается проблема исторической (культурной, национальной) идентичности России в понимании Петра Чаадаева, Владимира Соловьева и Федора Достоевского. Во всех трех проектах мы имеем дело с явно универсальными идеями. Однако далее в статье утверждается, что в этой русской универсалистской идеи и построенного на ней видения российской идентичности есть и более темная, сомнительная и даже опасная сторона. Эта идея может привести к решениям, к проецированию поспешных, опрометчивых, не столько ограниченных тяжестью жестких реалий, сколько не учитывающих реалий, трактующих их как почти сплошь пластичных и поддающихся давлению творческой и действенной субъективности. Это часто принимало форму сомнительного мессианства, избранности, особых сил, которые во имя спасительного или даже должного будущего не должны считаться с правилами и предписаниями текущего мира; это привело к таким видениям счастья, к которому принято принуждать, не  избегать в его реализации от порабощения и преступления.

Authors: Tian Zitong , Li Qiusheng
Published: May 2024

Facing the ethnic-cultural conflict in the relocation process and to promote ethnic-cultural integration, this study takes the ethnic interlocking communities in Guizhou Province as an example and uses research methods such as interviews and observation to collect data. The study also analyzes the influencing factors of cultural integration through regression analysis and proposes relevant measures. The results of regression analysis showed that cultural belonging, social support, community participation, and linguistic communication skills had a significant positive effect on ethnocultural integration while existing interpersonal relationships and identity had a significant negative effect on ethnocultural integration, with interpersonal relationships having the greatest effect on immigrants’ cultural integration, with a correlation coefficient of −0.260, followed by was the sense of cultural belonging with a regression coefficient of 0.240. Social support, language communication skills, community involvement, and identity were slightly less influential. Overall, the satisfaction levels after the migration were higher than before. Among them, the average satisfaction of immigrants with their income status before migration was 1.15. By building cultural exchange platforms and conducting targeted vocational training, new ideas have been provided for the integration of ethnic cultures in ethnic fusion communities. Research methods can effectively alleviate ethnic-cultural conflicts and promote ethnic-cultural integration.

Published: May 2024

Camellia oleifera Abel. shell (COS) is an agricultural waste in quantities exceeding a million tons annually. The ultrastructure of the COS cell wall and the distribution of lignocellulose components were investigated. The microscopic results showed that COS contains two types of cells, sclerenchyma cells (SC) and parenchyma cells (PC). SC contained 50.4 % hemicellulose, 17.6 % cellulose and 30.9 % lignin while PC contained 35.2 % hemicellulose, 23.7 % cellulose and 35.0 % lignin. The distribution of lignocellulose components in COS is non-homogeneous. Lignin is alternately distributed with polysaccharides in the PC wall. In SC, hemicellulose is mainly present in the secondary wall S2, while lignin was mainly found in the compound middle lamella, and cellulose mainly exists in the secondary wall, S3. A comprehensive model of the cell wall ultrastructure and lignocellulose distribution of COS was given. This study provides a fundamental understanding of COS cell walls and can aid in the future graded utilization of COS.

Published: May 2024

In this article, 3,4-dihydroybenzylidenehydrazine is synthesized for the first time, and its properties as a dopamine analogue for polymerization are investigated. Using an oxidative polymerization reaction, the reaction mechanism as well as the coating ability of the new polymer is determined and compared to that of polydopamine. The polymerization reactions were performed in a mixture of methanol–water with NaIO4 as an oxidation reagent. The polymer was used as a coating on both glass surfaces with a thickness of ∼5 nm as determined by AFM, as well as on TiO2 nanoparticles. For the latter, SEM/TEM and the pH-dependent variation of zeta potential were measured. As a free polymer, poly-3,4-dihydroxybenzylidenhydrazine was investigated by UV-Vis, ss-NMR, and FTIR, and a variety of monomeric units were found in the polymer matrix. The solubility in methanol or DMSO of the monomer and the slight solubility of the polymer allowed us to study the fluorescence and cyclic voltammetry properties for both the monomer and polymer.

Emerging contaminants are the outcome of the widespread usage of manufacturing advancements facilitating human life. These are found in various solid and liquid wastes discharged into nature. Sewage treatment plants across the globe receive a maximum quantity of various emerging contaminants from diverse sources. These contaminants reach soil, surface, and groundwater, affecting their quality. They also enter into the food web through different levels. This article thoroughly discusses the adverse effects of emerging contaminants and possible methods of remediation using activated carbon prepared from different materials. The review highlights the utilization of activated carbon for pharmaceutical and personal care products, pesticides, and a specific observation of caffeine removal. An in-depth online search for research and review articles gave an overview of technologies used and their reports with reference to the applicability of activated carbon as an adsorbent for emerging contaminants. Adsorption is considered to be one of the green methodologies for reducing contamination and making the resultant water of reusable quality. Biowaste materials are used for the preparation of activated carbon by chemical or physical modifications. These adsorbents can be used for removing emerging contaminants from wastewater/contaminated water. Many advantages of this method make it suitable for the treatment of effluent generated from various sources. The activated carbon quality, surface area for adsorption, and kinetics are of significance to ensure the quality and efficiency of the adsorbent.

Published: May 2024

One century after its initial excavation, this article presents the first absolute chronology for the settlement of Karanis in Egypt. Radiocarbon dates from crops retrieved from settlement structures suggest that the site was inhabited beyond the middle of the fifth century AD, the time at which it was previously believed to have been abandoned. These dates add to the complex picture of population fluctuations and the remodelling and reuse of structures at Karanis. Two dates reach into the middle of the seventh century, placing the abandonment of the site in a period of political and environmental transition that changed the physical and social landscape of the Fayum region and beyond.

Agrobiodiversidad en huertos familiares y seguridad alimentaria y nutricional de hogares en Monteverde, Costa Rica
Authors: Arias Ramírez Jéssica , Dumani Echandi Marcela
Published: May 2024

Agrobiodiversity is believed to be associated with a wider diversity of diets and a reduction in food and nutrition insecurity (FNI). Consequently, agrobiodiversity of home gardens and their potential impact on food and nutrition security (FNS) in households in San Luis, Monteverde, an area that previously experienced high levels of FNI, was researched.
A total of 23 households with family gardens was assessed, and the persons responsible for the gardens were interviewed to gather information about their households and their gardens. Additionally, plant and animal species were identified and their uses in those spaces were reported.
To measure household FNS, a scale focusing on the access component was applied. Results indicated that approximately 65.2% of households experienced some degree of FNI. Analyzing the possible correlation between agrobiodiversity and household FNS revealed a trend, households with more diverse home gardens tended to exhibit better FNS outcomes than home gardens with fewer species.
These findings suggest that well-managed agrobiodiversity in family gardens can play a significant role in improving the FNS of rural families.

Authors: Bustamante Olguín Fabián , Cerda Sanhueza Alejandro
Published: May 2024

This article aims to examine the views of the Chilean Catholic Church during the administration of President Salvador Allende. The main themes that arise from the declarations of the bishops will be addressed and the ethical-theological implications of the relationship between religion and politics in the current context will be analyzed. The central axis of the article is to analyze the vision of the bishops towards the Marxist/socialist ideology from the historical and theological analysis of the government of Salvador Allende and the configuration of Christians for Socialism. The bishops’ statements show a critical position towards the Marxist/socialist ideology, seen as synonymous in a discursive strategy of the church hierarchy to disqualify the government and the left-leaning of Catholics. The article is based on a classic analysis of texts, which uses internal and external analysis of episcopal documents between 1970 and 1974, together with a bibliographical review on the historical period.

Published: May 2024

En el caso de México, educar en contextos de vulnerabilidad y afectaciones sociales ha llevado a buscar otras formas de aproximarse al estudiantado para mejorar las relaciones interpersonales en el aula. Así, la Pedagogía de la alteridad, en el ejercicio de la docencia, reconoce la individualidad del estudiantado y busca atender sus necesidades desde una perspectiva ética y antropológica. Las cualidades docentes que destaca esta propuesta, como categorías son la responsabilidad, la acogida, la esperanza, el testimonio y la compasión hacia el estudiantado. En esta investigación de corte cualitativo, diseñada como un estudio de caso biográfico, se entrevistó a 11 miembros del profesorado, quienes trabajan en el sistema educativo mexicano en el nivel de educación básica, con el objetivo de identificar elementos de la Pedagogía de la alteridad en su práctica docente. Las entrevistas se analizaron a partir de la técnica de análisis de contenido. Los resultados arrojaron la presencia de todas las categorías de la Pedagogía de la alteridad en el discurso, especialmente sobresalieron la responsabilidad, la acogida y la esperanza. De igual manera, en las unidades de análisis, se vieron reflejadas intenciones y acciones enfocadas en el fortalecimiento de la relación entre el personal docente y el estudiantado en su contexto social, personal y académico. Se concluyó que la práctica de la Pedagogía de la alteridad puede considerarse como una alternativa que impacte positivamente en la disminución de problemáticas relacionales en el aula.

Authors: Ureña Pinto Melissa , Tencio Avila Kristel , Sibaja Molina Johanna
Published: May 2024

La pandemia por COVID 19 generó consecuencias en la niñez. La afectación a nivel social y psicológico se reflejó mundialmente debido a cambios como la ausencia de clases presenciales y el traslado de la educación a los hogares. Esto no solo significó un reto para la niñez, sino también para las familias y para las instituciones educativas a cargo del desarrollo de la regulación emocional de esta. Esta investigación, de corte cualitativo y abordada según la teoría fundamentada, analiza el papel de los factores protectores y riesgosos relacionados con el desarrollo de la regulación emocional en niñez de 4 y 5 años, que estuvo presente durante el contexto de la educación remota por motivo de la pandemia por COVID-19 en el año 2020. Para esto se realizaron 5 entrevistas virtuales con personal de una institución educativa, con 2 madres de estudiantes que estuvieron en preescolar en el año 2020, y con un grupo focal de 5 madres. Además, se realizó una actividad presencial de aproximadamente 40 minutos con dos grupos de estudiantes, a quienes se les enseñó el cuento “Monstruo de colores” para conversar e identificar emociones. Asimismo, se abrió un espacio para pintar y desarrollar un diálogo con el fin de conocer la perspectiva de la pandemia y el etiquetamiento de emociones que poseían. Se concluyó que, de manera similar a estudios internacionales, esta situación desencadenó cambios en rutinas cotidianas, alimentación, sueño, socialización con pares y cambios en las emociones de la niñez. A su vez, para las familias, supuso asumir un nuevo rol como personas educadoras para el cual no estaban preparadas. Se identificaron factores protectores y riesgosos como la escucha y el diálogo de las emociones, la comunicación entre familia y escuela, el apoyo en el proceso educativo, entre otros.

Se presentan dos unidades de análisis que fueron la base para la recolección de la información. La primera corresponde a los programas de ES comprendidos entre 1991-2016 que incluyeron el tema de las GRD, y la segunda, los libros de texto de ambas disciplinas que incluyeron información referente al problema de investigación. La información proviene de los planes de estudio del Ministerio de Educación Pública (MEP) desarrollados para el período de estudio y de diferentes bibliotecas donde se logró ubicar los libros de texto. Como resultado se obtuvo que la GRD contó con voluntad política para su incorporación en el sistema educativo, pero las propuestas curriculares fueron monótonas y con poca innovación. Los mismos resultados se obtuvieron del análisis de libros de texto, pues las actividades mostraron poco empeño didáctico por parte de las casas editoriales. Al ser un estudio exploratorio abre la posibilidad para plantear otras iniciativas con diferentes enfoques desde la investigación en ES.

A história na educação matemática pode proporcionar debates sobre o percurso de desenvolvimento dos conceitos, deixar as aulas contextualizadas e criar motivação na construção do conhecimento. Neste sentido, busca-se identificar os perfis dentro de um grupo de trinta discentes que são ingressantes do curso superior de ciência e tecnologia de uma universidade localizada no semiárido potiguar. Foi aplicado um formulário com itens elaborados em escala Likert, abordando a temática história da matemática. A partir de uma análise fatorial no software PSPP, os itens foram agrupados de acordo com as cargas fatoriais e seis perfis foram encontrados, sendo história na educação matemática aquele com a maior quantidade de participantes. Também foi verificada a experiência dos discentes com aulas de matemática que contemplem os aspectos históricos no ensino fundamental e médio. Diante dos perfis dentro deste grupo de participantes, pode-se ver a relevância da história da matemática nos processos de ensino e aprendizagem, bem como desperta uma reflexão para que a formação docente contemple a preparação para práticas envolvendo aspectos históricos.

This paper presents an approach for using a long short-term memory (LSTM)-based recurrent neural network with various configurations to construct a forecasting model for electrical load prediction of a 110 kV substation.
The issues of unbalances arising in energy management systems due to discrepancies between generated and consumed energy can lead to power outages and blackouts. With the introduction of the most accurate forecasts, the task of maintaining electrical reliability for grid operators can be greatly simplified.
Through an investigation into 81 different parameter combinations, the research revealed the optimal setup for an LSTM model in the task of electrical load forecasting. This configuration comprised 15 neurons, a batch size of 16, and employed the Adamax optimization algorithm. Applying this specific setup yielded a mean squared error (MSE) of 5.584 MW2 and an R2 value of 0.99. High R2 values and low MSE values indicate that the LSTM model accurately captures changes in electricity consumption with minimal deviation between predicted and actual consumption values. Selection of appropriate parameters significantly enhances the performance of the predictive model and resulted in a reduction of the MSE error from 12.706 to 5.584 MW2. The optimized configuration of the LSTM model, tailored through extensive experimentation, enhances its predictive capabilities.
The proposed LSTM model holds practical utility for integrating into systems for monitoring and forecasting mode reliability of electrical networks, particularly in the Western energy hub of the Republic of Kazakhstan. Its accuracy and reliability make it valuable for energy resource management and infrastructure planning
Results of the analytical solution of the problem of radial vibrations of disks of variable thickness
Authors: Trapezon Kirill , Trapezon Alexandr , Kalinichenko Vitalii , Didkovskii Vitaliy
Published: May 2024

An analytical solution is obtained for the problem of radial vibrations of disks of variable thickness. A disk is considered that is rigidly fixed along the inner circular contour (ρ=0.2) and free on the outer contour (ρ=1). The thickness of the disk varies according to the law H=H0(ρν+μ+Cρν-μ)2, where H0,C,μ are arbitrary constants; ν is the Poisson's ratio. The exact solution of the problem is known only for H=const and H=1/ρ3. However, these solutions are not sufficient to study the vibrations of disks of other configurations. The proposed law of thickness variation H(ρ) allows us to obtain exact solutions to the problem at any value of the constant coefficients H0, C, μ, ν. By varying the values of these coefficients within a single given function, it is possible to set the disk profile of the desired appearance. The methods used to obtain these solutions are based on appropriate mathematical transformations of the original equation.
The problem of disk oscillations is solved for four variants of thickness change. The natural frequencies for the first three forms of vibration are calculated. Comparison of the natural frequencies found for the three cases of the disk profile gently sloping indicates an increase in their values with an increase in the bending of the disk thickness. Based on the obtained eigenfunctions, the stresses were calculated and the nature of their distribution along the radial coordinate of the disk was determined.
The strength of the disks under resonant radial vibrations was evaluated using a special criterion. It is found that the most limiting, i.e., destructive principal stress σ1=σr at the first (main) form of vibration should be chosen from the ratio σr≈0.79 [σ-1], where [σ-1] is the endurance limit of the disk material under uniform loading. The results obtained can be used to predict the stress-strain state of disks of variable profile under their radial vibrations
Devising a method for improving pedestrian traffic safety when crossing railroad tracks by implementing an information system with a fixed warning time
Authors: Kovalchuk Vitalii , Lesiv Yulia
Published: May 2024

The object of research is pedestrian safety when crossing railroad tracks at pedestrian crossings. A method for improving the safety of pedestrian traffic when crossing railroad tracks within the area approaching the railroad pedestrian crossing has been developed, by introducing an information system for warning pedestrians about train movement with a fixed warning time.
Experimental measurements of the speed of the rolling stock were carried out in the area approaching the pedestrian crossing over the railroad track. With the mixed movement of trains, it was found that the lowest speed of the train was 67.46 km/h, and the highest was the passenger train – 131.9 km/h. At the same time, the speed of freight trains ranged from 74 to 79 km/h. Such data are needed to determine the speed of the rolling stock on the approach to the crossing or transition, which will allow the light and sound signal to be turned on in time when the movement of a pedestrian across the track will be dangerous.
The methodology for calculating the length of the approach section to the pedestrian crossing, depending on the speed of the rolling stock, has been given. It was established that the speed of the rolling stock has a significant effect on the length of the approach section. At the lowest measured speed of the train – 67.46 km/h, the length of the approach section was 317.46 m, and when the passenger train was moving at a speed of 131.9 km/h – 620.68 m.
For a single-track section of the railroad, a fixed time has been established for warning pedestrians about the approach of a train to the crossing. It is a constant value that is included in the warning information system on a single-track section, and after it, a complex light and sound alarm with an information board is activated, which will warn the pedestrian about the movement of the train. The method for improving the safety of pedestrian traffic with a fixed time of the pedestrian’s anticipation of the train movement could be used at crossings with pedestrian traffic, as a supplement to the crossing signaling subsystem in railroad transport. It can also be used at equipped pedestrian crossings over railroad tracks in urbanized areas. The advantage of introducing such a method is a fixed time to warn the pedestrian, in each specific case of the train approaching the crossing

The object of the study is decision support systems.
The problem of increasing decision-making efficiency in conditions of uncertainty and a set of different parameters was solved using a bio-inspired algorithm.
The subject of the study is the decision-making process in management problems using the heron flock algorithm, the improved genetic algorithm and evolving artificial neural networks.
A solution search method using the improved heron flock algorithm is proposed. The study is based on the heron flock algorithm to find a solution regarding the object state. Evolving artificial neural networks are used to train the heron flock algorithm, and an advanced genetic algorithm is used to select the best individuals of the heron flock. The method has the following sequence of actions:
– input of initial data;
– setting agents on the search plane;
– numbering heron agents in the flock;
– setting the initial velocity of heron agents;
– waiting strategy for heron agents;
– aggressive strategy;
– checking the discriminatory condition;
– selection of the best individuals from the heron flock;
– ranking and sorting the obtained solutions;
– training heron knowledge bases;
– determining the amount of necessary computing resources of the intelligent decision support system.
The originality of the proposed method consists in setting heron agents taking into account the uncertainty of the initial data, the noise degree of data about the analysis object state. The method makes it possible to reduce the time for decision-making at the level of 22–26 % due to the use of additional improved procedures. The proposed method should be used to solve the problems of evaluating complex and dynamic processes in the interest of solving national security problems
