Published: December 2024

The persistence of peroxydisulfate anion (S2O82−) in soil is a key factor influencing the effectiveness of in situ chemical oxidation (ISCO) treatments, which use S2O82− (S2O82− based ISCO) to remediate contaminated groundwater. However, only a few studies have addressed aspects of S2O82− persistence, such as the effect of temperature and the fate of sulfates (SO42−) generated by S2O82− decomposition in real soil and/or aquifer materials. Additionally, there are no studies comparing batch and dynamic column tests. To address these knowledge gaps, we conducted batch tests with varying temperatures (30–50 °C) and initial S2O82− concentrations (2.7 g/L and 16.1 g/L) along with dynamic column experiments (40 °C, 16.1 g/L) with comprehensively characterized real soil/aquifer materials. Furthermore, the principal component analysis (PCA) method was employed to investigate correlations between S2O82− decomposition and soil material parameters. We found that S2O82− decomposition followed the pseudo-first-order rate law in all experiments. In all tested soil materials, thermal dependence of S2O82− decomposition followed the Arrhenius law with the activation energies in the interval 65.2–109.1 kJ/mol. Decreasing S2O82− concentration from 16.1 g/L to 2.7 g/L led to a several-fold increase (factor 2–11) in bulk S2O82− decomposition rate coefficients (k′) in individual soil/aquifer materials. Although k′ in the dynamic column tests showed higher values compared to the batch tests (factor 1–3), the normalized S2O82− decomposition rate coefficients to the total BET surface were much lower, indicating the inevitable formation of preferential pathways in the columns. Furthermore, mass balance analysis of S2O82− decomposition and SO42− generation suggests the ability of some systems to partially accumulate the produced SO42−. Principal Component Analysis (PCA) identified total organic carbon (TOC), Ni, Mo, Co, and Mn as key factors influencing the decomposition rate under varying soil conditions. These findings provide valuable insights into how S2O82− behaves in real soil and aquifer materials, which can improve the design and operation of ISCO treatability studies for groundwater remediation.

This study conducted an in-depth analysis of the landslide problem in the loess hill and gully area in northern Shaanxi Province, selecting the loess landslide site in Quchaigou, Ganquan County, Yan’an City, as the object to assess the stability of loess slopes under the conditions of different plant root densities and soil moisture contents through field investigation, physical mechanics experiments and numerical simulation of the GeoStudio model. Periploca sepium, a dominant species in the plant community, was selected to simulate the stability of loess slope soils under different root densities and soil water contents. The analysis showed that the stability coefficient of Periploca sepium natural soil root density was 1.263, which was a stable condition, but the stability of the stabilized slopes decreased with the increase in soil root density. Under the condition of 10% soil moisture content, the stability coefficient of the slope body is 1.136, which is a basic stable state, but with the increase in soil moisture content, the stability of the stable slope body decreases clearly. The results show that rainfall and human activities are the main triggering factors for loess landslides, and the vegetation root system has a dual role in landslide stability: on the one hand, it increases the soil shear strength, and on the other hand, it may promote water infiltration and reduce the shear strength. In addition, the high water-holding capacity and permeability anisotropy of loess may lead to a rapid increase in soil deadweight under rainfall conditions, increasing the risk of landslides. The results of this study are of great significance for disaster prevention and mitigation and regional planning and construction, and they also provide a reference for landslide studies in similar geological environments.

Published: December 2024

Soil liquefaction is a major element influencing the behaviour of piles built in seismically active places. As a result, the first goal of this research is to investigate the seismic behavior of a soil-pile system in liquefiable soil using ABAQUS 3D and SANISAND as the constitutive model to simulate the seismic behavior of a liquefiable sand layer, including soil-pile interaction; the second goal is to apply an improved method of mitigating liquefaction potential in a sandy soil profile subjected to shaking. First, the finite element model was validated by comparing variations in pile reaction to measured data from the centrifuge test, and the numerical and experimental results were quite similar. Second, the effectiveness of consolidation in both the mitigation of a liquefiable soil and the reduction of induced pile relative settlement is showed.

Experimental and Numerical Analysis of the Potential Drop Method for Defects Caused by Dynamic Loads
Authors: Schneegans Erik , Zhang Jingrun , Hug Joachim , Rembe Christian
Published: December 2024

The potential drop method (PDM) is employed for defect detection in conductive specimens by measuring the change in impedance. Due to its ability to comprehensively monitor large structures entirely and its high sensitivity to material changes, PDM is a promising method for structural health monitoring (SHM) of specimens subjected to dynamic loads. However, PDM is rarely used in SHM because with increasing length and cross-section of the specimen, the defect sensitivity decreases. In this paper, we investigate how the electrodynamic proximity effect can be utilized by proper arrangement of the measurement setup to enhance the defect sensitivity of PDM in SHM applications. Our analysis shows that by proper arrangement of the measurement setup, the proximity effect enhances the defect sensitivity up to 300% compared to that of measurement setups in which the proximity effect is not utilized. Additionally, with proper arrangement of the setup, we found that the proximity effect linearizes the relationship between defect-induced resistance change and crack depth, facilitating the estimation of crack depth. We validated the results of the electrodynamic simulations for our PDM sensor experimentally by applying dynamic loads to a specimen via a resonance testing machine while measuring the defect-induced resistance change caused by a growing fatigue crack. Enhancing the defect sensitivity enables the SHM of larger specimens and thus improves the performance of PDM as an SHM technique.

Published: December 2024

The realization of full-color motion-picture holographic imaging with daily-use light is an important research objective. To achieve it, various types of single-shot phase-shifting incoherent digital holography (SSPS IDH) systems have been proposed up to now. Portability of the holography system is now strongly required to enable the application of holographic imaging to various scenes. Here, we propose a palm-sized full-color digital holographic camera system that can achieve both single-shot full-color incoherent holographic imaging and downsizing. An SSPS IDH system with a color polarization image sensor is adopted, and a compact optical system exploiting 2 thin polarimetric phase-modulation optical elements is constructed. Full-color motion-picture holographic imaging at the frame rate of the image sensor is experimentally demonstrated using white light with a continuous-wavelength spectrum. This camera enables full-color 3D motion-picture recording under the condition that a reflective object is set close to the holographic camera. An antivibration structure is no longer needed.

Published: December 2024

To address the high rate of grain loss in the two-stage harvest of buckwheat, a pickup-tooth conveyor belt type buckwheat pickup device was developed to mitigate the grain loss in the buckwheat pickup process. The critical components of the pickup mechanism and conveyor mechanism were designed, and the essential parameters were determined. The operational efficiency of pickup-tooth conveyor belt type buckwheat pickup device was verified through field orthogonal test. The field test results indicate that the loss rate is most significantly affected by the speed of the pickup device, followed by the tilt angle of the pickup-tooth. The forward speed of the machine exerts minimal influence. After the multi-objective parameters of the regression equation model were optimized, the optimal parameters of the factors were obtained: the forward speed of the machine of 0.8 m/s, the pickup speed of 1.1 m/s, as well as the pickup-tooth tilt angle of 0°, Under the above condition, the loss rate of buckwheat grain reached 6.92%.

Life quality and social integration of migrants settled in Chile: Venezuelan Narratives
Authors:   Liliana Acero and Pablo Zuleta Pastor
Published: December 2024

Local economic crisis, violence and permanent political uncertainty, especially in some developing countries, has led to a massive migration of Venezuelans, lately to other countries of South America, looking for better living conditions or mere subsistence. The total number of Venezuelans living in Chile had reached until 2022, 532.715 individuals, representing 32,8% of the migrant population in the country. Since 2014, Venezuelans have arrived in waves with different social, economic and cultural characteristics. This paper presented a qualitative analysis of the effects of selected indicators on the quality of life and social integration of ten Venezuelan migrants in Chile by gender, age and class, as narrated by themselves. Its aim was to explore their socioeconomic and cultural trajectories during settlement in Chile and show how they affected their resilience strategies and social integration. Findings showed a precarious stability in life quality, devaluation of their work and professional status, daily suffering of a variety of maltreatment forms and injustices, most especially, though not only at work. The resilient strategies they have followed involve regrouping among compatriots, certain emotional isolation from nationals, absence of or mild confrontation of ill-treatment, as well as denial of migrant discrimination as a marked social trend.
Mutual Exploration for Missing Data Imputation, QoS Parameter Selection, and QoS Prediction in 5G Networks Using a Novel Skewness Driven Distribution Imputation Algorithm, Pearson Correlation, and XGBoost
Authors: Khan Saifullah , López Onel Luis Alcaraz , Khattak Abdul Basit
Published: December 2024

Pre-processing is a key stage in the Machine Learning (ML) pipeline. In such a stage, data is prepared and organized for feeding it to the ML models for a prediction task. One of the problems that might incur in this stage is that data may have missing values, requiring that either the data is deleted or imputed with data points that resembles/ correlate with the original one. Imputation is desirable, as having more data to be fed to ML models means the model will have more context and thus better prediction results. From an imputation perspective, since the goal is that the imputed data faithfully relates with the original data, the result of correlation metric is desirable to show that the imputed data and original data are closely correlated. Herein, we present a novel imputation algorithm of Skewness Driven Distribution Imputation (SDDI), and evaluate its efficacy compared to multiple state-of-the-art methods including, K-Nearest Neighbors (KNN), Mean, Mode, Forward and Backward Fill (F&B-Fill) imputation methods. The comparison is done using accuracy metrics, Root Mean Square Error (RMSE), correlation and computation time. Furthermore, a correlation analysis is conducted on the subject 5G Vehicle-to-Everything (V2X) Quality of Service (QoS) dataset, aiming to enhance the understanding of parameter selection in assessing the QoS for 5G networks by providing the comparison regarding the significance in terms of correlation of various parameters in influencing 5G network's QoS. The state-of-the-art Pearson correlation method is used for said purpose. Moreover, we exploit an Extreme Gradient Boosting or XGBoost algorithm which is an ensemble of other techniques and not as complex as deep learning algorithms, to predict QoS, given certain conditions relevant to the 5G network. The comparative analysis of various imputation methods revealed average correlation values (as a measure of faithful data imputation) to be relatively close for Mean, Mode, F&B-Fill, SDDI, and K-Nearest Neighbors imputation methods at 0.161, 0.176, 0.143, 0.143, and 0.196, respectively. In terms of accuracy, all methods achieved high rates, with Mean and Mode at 93%, F&B-Fill at 90%, and both SDDI and KNN at 92%. Notably, in the second part of the research, when only the 15 most correlated features were used, we observed a substantial 60.5% reduction in the amount of data affected, with only a minimal impact of 3% on accuracy, achieving an impressive 93% accuracy. These results highlight the effectiveness of targeted feature selection of parameters for QoS of 5G networks and underscore the potential of our novel SDDI method in maintaining high data integrity while efficiently handling missing data, thereby enhancing the predictive reliability of the XGBoost algorithm.
An Examination of Degrowth Frameworks: Localizing, Socializing, and Regenerative Tourism
Authors: Akhoundoghli Mahshad , Boluk Karla
Published: December 2024

A growth-driven market and orientation are recognized as responsible for mass tourism, overtourism, tourism resource degradation, and significantly, the acceleration of the climate catastrophe. In response to the inimical impacts generated by the tourism sector, several responses have
emerged to pave a way for more intentional and responsible ways of cocreating tourism approaches that generate benefits for the destination communities where tourism takes place. Regenerative tourism, localizing tourism, and socializing tourism have intentionally been centered as responses
to growing concerns in tourism; however, there is a paucity of scholarship exploring the unique attributes of each framework exploring how they may work together to advance just futures in tourism. To respond to this gap, we examined the three degrowth frameworks by adopting an Interpretive
Grounded Theory methodology guided by constant comparative analysis. The aim of our analysis is to examine each framework to consider the common threads, determine what sets the frameworks apart, and importantly, consider how they may fit together. Our analysis reflects on how pulling on the
strengths of each of the frameworks may provide the much-needed guidance for tourism stakeholders interested in supporting a more inclusive and impactful tourism sector in consideration of just futures.
Changing Attitudes to Monasteries in the Peasant Communities of the Arkhangelsk Province in the Early 20th Century
Authors:   Kenozero National Park, Kharitonova Yana E.
Published: December 2024

The decay of the patriarchal rural life, which intensified at the turn of the 19th century, caused a transformation in religious beliefs among the peasantry. The establishment of Soviet rule accelerated the changes in the position of the Orthodox clergy, parishes and monasteries. The author examines the reasons behind this process, which was affected by the economic, political and intra-church transformations in the life of Russian society. Further, the consequences of changes in the religious sentiments of peasants are explored, such as the decline in the clergy’s authority, separation of church life from everyday life of the peasant community, and secularization of peasant consciousness, which facilitated the claims of local residents for monastic property. Cases of plundering by local dwellers in 1917–1918 are studied using the examples of the following men’s monasteries: Onega Cross Monastery, Archangel Michael Monastery, Kozheozersk Monastery, Krasnogorsk Monastery, and Pechenga Monastery, as well as women’s Kholmogory Monastery. The peasants tried to justify their actions by saying that they had the right to take away land and property from the monasteries according to the decree “On the Separation of Church from State and School from Church”. The author comes to the conclusion that cases of disorderly conduct towards northern monasteries were recorded long before the revolutionary events of 1917. In the early 20th century, some monasteries turned to the police or volost authorities for protection. All Arkhangelsk monasteries were closed after the end of the allied intervention and the ouster of the White Guard. Subsequently, monastic lands were taken over by agricultural communes and artels consisting of local residents and controlled by the Soviet government, while the monastics were dismissed. This article broadens our understanding of the reasons behind the changes in the peasants’ religious worldview and highlights the most striking facts of interaction between northern monasteries and local peasants during the period under study. The results can fill the existing regional information gaps in the history of interactions between northern monasteries and the local population in the early 20th century and help to understand the building up of relationships between the reviving northern monasteries and the local population today.

Authors:   Peoples’ Friendship University of Russia named after Patrice Lumumba, Mikheeva Natalia F. , Popova Evgeniya A. ,   Moscow State Linguistic University
Published: December 2024

The article deals with the didactic potential of the non-academic corpus of the Spanish language Corpus del Español, created by M. Davis. The purpose is to reveal the scope of options of this corpus for students and teachers in classes of Spanish as a foreign language. Among the four Corpus del Español subcorpora (Género/Histórico; Web/Dialectos; NOW 2012–2019; Google Books n-grams), particular attention is paid to the subcorpus of Internet resources of the national varieties of Spanish: the article points out its advantages over other subcorpora, taking into account the latest functions, as well as presents information search options and describes the procedure in detail. Specific examples demonstrate the principles of using the corpus in intervariant research (studying the frequency, semantic and pragmatic features of separate words as well as their lexical and grammatical collocations in the national varieties of the Spanish language). In addition, the paper suggests assignment ideas for students of different levels (from simple introductory and search exercises to rule formulation), taking into account both advantages and disadvantages of using the corpus in the classroom. A conclusion is drawn about the importance of using this tool for linguodidactic purposes due to the wide scope of its functions and easy access to them, which allows one to stimulate students’ inductive activity, increase their motivation and develop a creative approach to learning activities. The article outlines prospects for further work in the field of corpus research related to the study of Spanish as a multinational language in all its diverse manifestations.
International, Intercultural and Global Dimensions of the Internationalization of Higher Education: A Socio-Philosophical Approach
Authors:   Siberian Institute of Management, Branch of the Russian Presidential Academy of National Economy and Public Administration, Beregovaya Oksana A.
Published: December 2024

The topic of the internationalization of higher education has received wide coverage in recent years due to the democratization, massification and liberalization of higher education and the need for countries to enter the global educational space. Internationalization of higher education is a dominant trend in the development of global processes. The article dwells on the methodological issues of studying this phenomenon. Current internationalization of higher education is considered in three dimensions – international, intercultural and global – using the examples of institutional interaction between national education systems, educational organizations and participants in educational relationships. Based on the existing points of view, a new methodological approach is proposed, i.e. a comprehensive representation of the internationalization of higher education within the framework of social philosophy. The latter allows us to link up different aspects of this phenomenon and synthesize the most common and holistic ideas. The analysis showed that the internationalization of higher education is a purposeful process of interaction between national education systems at the global, international and intercultural levels taking into account institutional, organizational and interpersonal components. The main conclusion of the paper is the idea that internationalization is a complex phenomenon that has become ambivalent. On the one hand, it is considered to be an incentive for the development of national education systems, the role of universities and the motivation of students, and on the other hand, it leads to inequality in education, dominance of some educational systems over others, and greater influence of the English language. Russian education is faced with the task of creating attractive opportunities for applicants from abroad, taking into account, first of all, the national interests and the needs of the Russian higher education system. In addition, the article outlines prospects for further study of internationalization.
Phenomenology of Virtual Reality Perception
Authors:   Ufa University of Science and Technology, Elkhova Oksana I.
Published: December 2024

The article dwells on the phenomenology of perception of virtual reality, which is understood as an entity temporally situated in being. It is emphasized that virtual reality originates at the moment of being’s self-disclosure to the entity as a result of human interaction with technologies that create sensory impressions. The article analyses the current state of virtual reality technologies, which are mainly limited to sound, video, and tactile sensations. An obstacle to the widespread use of smell and taste simulation in virtual reality is the problem of user safety. In the future, taste and smell digitalization will allow us to engage all exteroceptive sensations, making virtual experience more realistic. The author highlights innovative developments in this area. In virtual reality, the physical body remains significant and plays an important role in virtual perception. Despite substantial advancements in virtual technologies, the user’s perception in virtual reality stays closely linked to the physical body due to the active vestibular and complex proprioceptive systems. The author applies the theory of field behaviour to the virtual sphere, which opens up new prospects for understanding the user’s interaction with the virtual environment. The author’s concept of field behaviour in virtual reality is presented, distinguishing field interference between the real and the virtual, as well as superposition of the real and virtual components in human perception of virtual reality that are merged by the human brain into a single perception.

An approach to probabilistic assessment of field development forecast parameters for gas-condensate reservoir using multi­variant simulation was studied. The necessity of such decision may be explained by the aim to level the influence of large number of uncertainties which occur during the work with res­ervoir simulation models. «tNavigator» software was used as the main instrument since it provides wide functionality in the sphere of interest. The variants of variables implementation were studied, the review of experimental designs and optimiza­tion algorithms was done. At the first step, the simulation model was history matched using Differential Evolution algorithm, since its initial version had problems with phase withdrawals and pressure dynamics. Corresponding history matching qual­ity was controlled by specially generated objective function val­ues. At the second step a series of production forecasts based on the best history matching cases was calculated; cumulative distribution functions for field development parameters under consideration were received to get the necessary probabilistic assessment. As a result, the workflow for values of interest get­ting was provided; also, the variants of further modifications for studied approach were formulated: the number of simulation runs can be decreased through the choice of three base vari­ants and use of multi-dimensional scaling which provides the opportunity for realizations of equal probability clustering with further choice of representative cases.
Historical memory and the dialogue of cultures in the context of Georgian-Russian interaction

Published: December 2024

Introduction. The modern history of Georgian-Russian relations is marked by relapses of the Cold war. The dividing line between nations has passed, with a centuries-old history of relationships. The article analyzes a complex of reasons causing mutual misunderstanding between states and peoples, who made a significant contribution to the development of world civilization. It is noted that the modern process of Georgian-Russian relations is significantly influenced by the legacy of the past, its interpretation by representatives of the intellectual community and the ruling elites. It is shown that in addition to this, deep culture, which preserves the civilizational and cultural layers of centuries-old interactions, also has a significant influence on the Georgian-Russian dialogue.
Materials and Methods. The work is based on the principles of historicism, objectivity, scientific character, a comparative-historical, cultural-civilizational approach to the analysis of Georgian-Russian relations was used. The article is written on the basis of archival materials from the Central Historical Archive of Georgia, which preserves the historical memory of the origin and development of Georgian-Russian relations. Criticism of modern interpretations in the studies of Georgian historians is also given.
Analysis. The analysis of modern research shows that the history of Georgian-Russian relations has undergone revision and transformation, the ideologeme of negativism dominates in the perception of relations. The emphasis is on the imperial, colonialist policy of the Russian Empire, the period of the USSR, as well as modern Russia in relation to Georgia. Political myths are created; the politicization of history highlights the negative aspects of relationships and creates obstacles to the search for a dialogue of cultures. Thus, those civilizational and cultural layers that were created over centuries of relationships are ignored.
Results. The author argues that overcoming political myths will create conditions that will ensure the normalization of relations between countries, return Russia to the role of spiritual mediator in the Caucasus region, and Georgia to its worthy place in the community of democratic states of the Caucasus.
Some problems of forming resort legislation in the Russian Federation

Introduction. The article examines the problems of the formation of resort legislation, including the novels introduced in the Federal Law of 23.02.1995 No. 26-FZ (as amended of 04.08.2023) "On Natural Therapeutic Resources, Therapeutic Areas and Resorts", which come into force on September 1, 2024.
Materials and Methods. In the course of the study, methods of legal analysis, synthesis, generalization and comparative legal were used, which made it possible to develop possible ways to solve the studied problems.
Analysis. Resort legislation in our country arose in the 18th century and developed relatively adequately to socio-economic and environmental realities, responding to new norms and institutions to emerging challenges. Designed to protect natural healing resources as the basis for the treatment and prevention of diseases, to protect other natural resources and natural complexes as the ecological framework of resorts, it went through several stages: Pre-revolutionary, Soviet and Post-Soviet. The Post-Soviet stage can be divided into several more: from environmentally sound (environmental expertise was carried out for all facilities under construction and reconstructed), organizationally secured (suffice it to recall the creation of the Administration of the Caucasian Mineral Waters with broad powers) to the current one, which is characterized by de-ecologization (in 2013, resorts were excluded from the composition of specially protected natural areas). The updated resort legislation envisages re-establishing the boundaries of the district of sanitary (mountain-sanitary) protection and the boundaries of protection zones within the districts and they are likely to be reduced. For the first time in the history of resort legislation, a norm is introduced on the procedure for the possible abolition of a therapeutic area, resort or resort region.
Results. The article analyzes the current resort and related legislation, as well as the norms that will come into force in the near future and proposes measures to improve them.
Phatics and pragmatics of the headline in sports discourse in forming a provocative narrative
Authors:   North-Caucasus Federal University, Zahra O. V.
Published: December 2024

Introduction. Nowadays a constitutively determined description of sporting events becomes a powerful tool for the formation of national ideology and culture. The study of headline complexes in sports publications provides an insight into the mechanisms of manifestation of phatic and manipulative functions, which are currently dominant in the language of the media.
Materials and Methods. The article, based on a contaminated classification of the discursive significance of sports news and discourse-modus analysis, taking into account the focus of the addressee, analyzes various types of headlines as basic codes for interpreting the main text of messages, their main functions and the functional pragmatics of influencing a hypothetical recipient.
Analysis. Particular attention is paid to the comparison of specifiers of phatic and informational orientation as the most representative mechanisms of bidirectional vectors operating within the framework of increasing the relevance of the described event and the socio-cultural and ideological phenomena associated with it. The author argues that the use of manipulative and phaticoexplicatory techniques in headlines realizes the maximum perlocutionary effect, if a balance between episodic sensationalism and operational information content is maintained. Taking into account the complex of axiological dominants in the compressed space of the title is recognized as a basic condition for attracting the attention of a wide range of readers; and the use of units that mark the exclusivity and episodic determinism of the described news item is the most effective methods for realizing the maximum manipulative effect.
Results. The headline complex is the most compressed regulatoryphatic model of the entire text of the description, which includes settings for interpreting the entire description and specifies the axiological vectors for evaluating the news feed. At the same time, the strong position of the text, which the title represents, activates the attention of the readership through provocative narrativization, affecting associations with other socially significant areas.

Pupillometry is a popular method because pupil size is easily measured and sensitive to central neural activity linked to behavior, cognition, emotion, and perception. Currently, there is no method for online monitoring phases of pupil size fluctuation. We introduce rtPupilPhase—an open-source software that automatically detects trends in pupil size in real time. This tool enables novel applications of real-time pupillometry for achieving numerous research and translational goals. We validated the performance of rtPupilPhase on human, rodent, and monkey pupil data, and we propose future implementations of real-time pupillometry.
