Particle size effect on the mechanical behaviour of coral sand - geogrid interfaces
Authors: Chao Zhiming , Zhou Jiaxin , Shi Danda , Zheng Jinhai
Published: January 2025

Particle size distribution (PSD) of coral sand is a critical factor that influences the mechanical properties at the coral sand-geogrid (CS-GG) interface, which is affected by both particle breakage and various temperatures. However, relevant researches are scarce currently. This study conducts a series of large-scale interface shear tests on coral sand with three PSD ranges (0.25∼1mm, 1∼2mm, and 2∼4mm) at varying temperatures (5°C∼80°C). Experimental results demonstrate that the IB value at the CS-GG interface ascends and then descends with the increase of PSD from 20°C to 40°C. The IB value at the interface descends and then ascends with the increase of PSD from 60°C to 80°C; The PSD curves at the interface indicate that the particle breakage degree of coral sand increases with rising temperature (5°C∼40°C); The larger PSD of coral sand, the smaller fractal dimensions (D) of the interface; A mathematical formulation of the relationship between the relative breakage rate (Br) and the D value at interfaces is presented, which considers temperature effects; The relationship between the total input energy (E) and the Br value has been expressed by empirical formulations with different PSD ranges, where the fitting curve for 2∼4 mm coral sand exhibits a hyperbolic pattern.

Authors: Podstawski Robert , Borysławski Krzysztof , Grodź Daria
Published: January 2025

Background: The purpose of this study was to evaluate the reliability and validity of a new repeated maximal rowing test (RMRT) in young volleyball players; Methods: Thirteen Polish volleyball players aged 17.98±0.51 years took part in the study. Body height was measured with an InLab S50 stadiometer, and the remaining body composition parameters were determined by bioelectrical impedance with the InBody 270 Bioelectrical Impedance Analyzer. The decrease in power generated during the 5 x 20-s RMRT was assessed on a Concept 2 PM5 rowing ergometer. Results: Power values were significantly higher (p<0.001) in intervals 1 and 2 (as well as in interval 3 in session II) than in intervals 4 and 5. In turn, the values of mean and maximum heart rates (HRavg and HRmax) were significantly higher (p<0.001) in intervals 4 and 5 (and partly in interval 3) than in intervals 1 and 2. In both measurement sessions, power was most significantly correlated with total body water and proteins (p = 0.050 - 0.006, respectively), minerals (p = 0.072 - 0.008), fat-free mass and basal metabolic rate (p = 0.050 - 0.005), skeletal muscle mass (p = 0.045 - 0.005), and body mass (p = 0.060 - 0.009); Conclusions: The 5 x 20-s RMRT is a valid and reliable test for assessing maximal anaerobic power in young volleyball players. The results of the 5 x 20-s RMRT revealed the presence of a linear trend indicating that power decreased in successive intervals due to the growing levels of fatigue among players.

This study examines the relationship between parental support and involvement in sports and the prevalence of overweight and obesity among Pakistani children and adolescents aged 9-17 years. Using a cross-sectional design, the study used a multistage random cluster sample from 62 schools with 4,200 students. Data from 4,108 participants (97.8%) were analysed, with 92 (2.2%) excluded due to incomplete information. Body weight status was assessed according to WHO guidelines. Results showed that among 3,371 students (mean age = 13.74 years, 58.2% boys), higher parental support and involvement in sports were significantly associated with healthier weight status. Descriptive statistics showed that 15.8% of the children were underweight, 57.1% had a healthy weight, 16.8% were overweight and 10.3% were obese. Significant associations were found between parental encouragement to exercise and weight status (χ2 = 13.39, p = 0.005). Logistic regression showed that parental encouragement (B = 0.138, p < 0.001) and financial support (B = 0.099, p < 0.01) were positively associated with healthier body weight. In contrast, lack of involvement was associated with higher rates of obesity.
Asymmetric Effects of Trade Openness and National Income on Government Size in BRICS Countries: New Evidence for Wagner’s Law
Authors:   Pandit Deendayal Energy University, Mehta D. , Patel N. ,   Nirma University
Published: January 2025

The growing economic prominence of BRICS nations (Brazil, Russia, India, China, and South Africa) has attracted considerable attention to the macroeconomic dynamics driving their development. As these economies grow rapidly and become more integrated into global markets, it becomes increasingly difficult to balance economic growth, trade liberalization, and sustainable fiscal policies. Government size, a key factor in fiscal management, tends to increase with national income (as suggested by Wagner’s Law) and in response to trade openness (as outlined by the Compensation Hypothesis). Understanding these dynamics is crucial due to the unique fiscal pressures and global competitiveness faced by BRICS countries. This study investigates the validity of Wagner’s law and the Compensation Hypothesis in the context of BRICS. Using a panel nonlinear autoregressive distributed lag model on annual panel data from 1999 to 2023, our findings confirm Wagner’s law, showing a positive relationship between economic growth and government size. Additionally, the results support the Compensation Hypothesis, indicating that trade openness enhances government size. This study underscores the potential trade-offs between promoting economic growth and trade liberalization, as these strategies may inadvertently expand the government sector and affect fiscal stability. As BRICS economies continue to integrate into global markets, this research contributes to the discussion on Wagner’s law and trade openness, offering new insights into sustainable fiscal policies, government expenditure optimization, and the pursuit of global competitiveness and economic growth within the BRICS framework.

In 2018, China adopted the Environmental Protection Tax Law, transitioning from administrative fees to statutory taxes. The law aimed to incentivize enterprises to reduce pollution emissions through economic means, improve environmental quality, and promote the optimization and upgrading of industrial structures for economic development. This study seeks to reveal the mechanisms of the impact of environmental protection tax on regional economic effects, providing policy recommendations for achieving high-quality economic development and ecological environmental protection. The study analyses four key variables—environmental protection tax revenue, regional industrial output value, regional GDP, and regional industrial pollution control investment—from 31 regions in China between 2018 and 2022, forming a sample of 30 observations. A random effects model is constructed and empirically analysed using Python 3.12. The empirical results show that for every additional unit of environmental protection tax, the average expected growth of regional GDP is 0.1043 units. There are significant differences in the economic effects of China’s environmental protection tax on regions, and these differences have random effects. This study provides new insights and empirical evidence for understanding and evaluating the impact of environmental protection taxes on regional economic outcomes, helping policymakers assess current impacts and continue encouraging enterprises to adopt clean production technologies, improve energy efficiency, and promote economic structure optimization and industrial upgrading to support high-quality economic development.

The article considers the influence of geometrical parameters of the anode part of a bipolar plate on the gas-dynamic and electrical characteristics of a fuel cell with a proton exchange membrane. A model of a composite fuel cell bipolar plate with a proton exchange membrane has been developed by the finite element method using the COMSOL Mul-tiphysics software package. It has been established that the optimum rib width of the anode part supply channel of a bipolar plate is in the range of 3-4 mm. Increasing the rib width above this range will lead to deterioration of the mass transfer process and increase in the contact resistance. Reducing the width of the channel rib will lead to a decrease in internal pressure, deterioration of mass transfer and consequently a decrease in the performance of the proton ex-change membrane fuel cell. The model allows significant optimization of the bipolar plate geometrical parameters. The obtained results represent initial data for the development of composite bipolar plates for the power supply systems based on proton exchange membrane fuel cells.
A posteriori approach for estimating the signal-sampling interval on the basis of interpolation by bordering functions
Authors:   Platov South-Russian State Polytechnic University (NPI), Sedov Andrey , Zharikov Kirill ,   Platov South-Russian State Polytechnic University (NPI)
Published: January 2025

The article considers the approach, estimating correctness of sampling frequency selection at measurement of physical processes from the point of view of distortions introduced by discrete signal representation. It does not require multiple repeated measurements of the signal with different uniform sampling intervals and the use of computationally complex spectral transformations. A single measurement of the signal with a fixed uniform sampling interval, as well as several control points at time instants that are not multiples of the selected frequency, is implemented. Application of the inter-polation formula with bordering functions allows estimating the values in the selected control points from the uniform signal samples. Based on the comparison of calculated and measured values in the control points, the conclusion about the quality of sampling frequency selection is made. The used interpolation does not require calculation of the coeffi-cients of the interpolating trigonometric polynomial or spectral characteristics, and the estimation is carried out ‘by nodes’, similar to the way it is realised in the interpolating Lagrangian polynomial. The approach reveals the presence of distortion both for the case where the observation interval is the period of the signal and for the case where it is not the period of the signal. The second case is more complicated, as in this case, due to the effect of spectrum spreading, there is additionally a distortion of the measured signal, which can be incorrectly attributed to the wrong choice of the sam-pling interval due to the failure to fulfil the condition of the sampling theorem. To identify this case, the article proposes using a special application of time windows to the occurring errors at the control points on the observation interval.
The Effect of Rater Discussion on Rating Characteristics in Korean Writing Assessment
Authors:   The Korean Society Of Bilingualism, Kang Min Suk
Published: January 2025

The purpose of this study is to analyze the effect of rater discussion on rating characteristics in Korean writing assessment and to propose a practical method for ensuring scoring reliability that can be applied in Korean language education settings. A group of 29 raters participated, initially scoring 15 writing samples independently, then engaging in group discussions to resolve scoring discrepancies, followed by scoring another set of 15 samples. The Many-Facet Rasch Model (MFRM) was used to evaluate changes in rater characteristics, including severity, consistency, and bias. The findings showed that rater discussions effectively narrowed the range of severity, leading to a more centralized distribution of scores. Consistency also improved, with fewer raters displaying inconsistency in the second round. Moreover, the occurrence of significant bias diminished, suggesting that discussions helped mitigate tendencies toward leniency or harshness. These results indicate that rater agreement not only enhances rater expertise but also contributes to establishing a shared understanding of evaluation criteria among raters.

The arrival of the railway to Álora in 1865 opened up new perspectives for economic development, which continued from 1903 with the construction of reservoirs for the production of electricity, allowing the establishment of other factories. Engineer Rafael Benjumea built the El Chorro and Guadalteba waterfalls on both sides of the impressive Los Gaitanes gorge, and a narrow high-altitude walkway to connect them. Its restoration has opened up new tourist perspectives for this area based on the landscape and industrial tourism. Currently, the candidacy of the Caminito del Rey is being promoted to be included in the UNESCO world heritage list. To carry out this work, documentation from the Provincial Historical Archive of Malaga, specialized bibliography has been handled, and exhaustive field work has been carried out.
Visuality in Modern Thought: Machiavelli, Art and Politics
Authors: Mollaer Fırat
Published: January 2025

For many commentators, modernity is the triumph of the eye over the ear, of the visual over the auditory. In other words, modernity is, among many different components, the establishment of a new regime of seeing. This is one of the reasons why the beginnings of modernity are sought in the Renaissance. In the Renaissance period, two distinct themes explain the emergence of visuality in modern thought: Perspective art and Machiavellian thought. Both perspective and Machiavellian thought have been considered as the roots of modernity. Drawing on an interdisciplinary encounter between art theory and political theory, perspective and Machiavelli, this article examines the emergence of visuality in Machiavellian thought in terms of a dialogue with perspective, but underlines the differences between these two conceptions and argues that Machiavellian thought proposes a politics beyond perspective.

The method of thermomigration of liquid zones in single-crystal silicon is already quite widely used in microelectronics and microsystem technology and continues to develop. The article provides a brief overview of new technical solutions published over the past ten years that make it possible to expand its applied potential. One of the areas of research is the development of processes for using gallium as a zone material. This makes it possible to increase the level of doping of the formed thermo-migration channels twice as compared to the aluminum currently used. The transition to a new zone-forming material leads to the formation of sharper p-n junctions at the boundary of the recrystallized regions with the silicon substrate and thereby increases their insulating properties. An increase in the doping level also leads to an increase in the electrical conductivity of the formed channels. Both of these factors contribute to expanding the scope of application of thermomigration processes. Another new area of research are experiments on the use these processes in the modification of optical fibers with a silicon core. Their transparency in the infrared range allows the use of laser radiation to create a temperature gradient. Precision focusing of the beam in the local area of the optical fiber allows it to achieve its value in the melt zone at a level of 4500...5500 K/cm, which is an order of magnitude higher than in installations with lamp or resistive heating. The stages of introducing GaSb inclusions with light-emitting properties into structure of the optical fiber and its on-chip mounting were worked out. This potentially opens up the prospect of creating a new technological platform based on the integration of the optical and electronic properties of semiconductor materials contained within an optical fiber.

Debunking the myth: usage of thiamine in cervical preparation and labour augmentation
Authors: Suryawan A. Z. , Nisa A. Sh. , Santoso D.P.J. , Slamet S. A. , Handono B.
Published: January 2025

In Indonesia, thiamine (B1) has been use for cervical priming and enhancing uterine contraction in midwife and hospital setting as its off-label effect. However there are no clear evidence and research related to this issue. Thiamine itself was founded in 1990’s and has been used extensively as labour augmentation in 1940–1960’s. Main hypothesis previously due to B1 increased function of the uterine body and lower uterine segment obliteration during labour which also responsible for the reduction of pain. Thiamine also assumed to promote stimulation of uterine contractions by direct participation in nerve impulses that regulates and establish the rhythm of uterine contractions and also inhibits action of cholinesterase which reduce acetylcholine clearance. However recent research proves B1 mainly function in Krebs cycle specifically in decarboxylase of pyruvate to acetyl-CoA in form of thiamin diphosphate, synonymously known as thiamine pyrophosphate. Due to clear foundings of B1 function in cell energy metabolism, study of B1 in labour augmentation was not continue further. It’s also related to uterine contraction function in labour not relied on it’s paracervical parasympathetic ganglia which respond to acetylcholine but rely heavily on oxytocin and its receptor. As conclusion, the author stated B1 have no effect on labour progression however could prove beneficial if the mother has B1 deficiency as it’s could reduce energy output from cell which could affect myometrial contraction.

Real-world treatment patterns of patients with acute coronary syndrome based on 15-year data
Authors: Egorova Inga S. , Vezikova Natalia N.
Published: January 2025

BACKGROUND: About half a million cases of acute coronary syndrome (ACS) are diagnosed in Russia every year. However, despite optimized treatment of patients with ACS, mortality remains high, which dictates the need to analyze the effectiveness of therapeutic measures.
AIM: To evaluate the real-world clinical features, treatment approaches, and outcomes in patients with ACS based on data from the long-term registry of the Regional Vascular Center.
MATERIALS AND METHODS: The study included consecutive 8 347 patients admitted to the Regional Vascular Center of the Republic of Karelia for ACS in 2008–2023. The clinical features, drug therapy, reperfusion interventions, complication rate, outcomes, and mortality were evaluated. The effectiveness of therapeutic measures in patients with ACS was analyzed using the obtained data and a 15-year real-world register.
RESULTS: The study included 8 247 patients, and there were more men (4 989 patients; 60.5%); 1 502 (18%) patients had a history of myocardial infarction; 4 741 (56.8%) were diagnosed with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). In the study group, 4 481 (53.7%) emergency percutaneous coronary interventions (PCI) were performed for ACS. For ST-segment elevation acute coronary syndrome (STEACS), 2 928 (81.2%) patients had PCI, and 228 (7.8%) patients had thrombolytic therapy followed by PCI. Thrombolysis was performed in 113 (43%) and 150 (57%) patients before and after hospitalization, respectively. Efficacy criteria were determined in 57 (50.4%) and 107 (71.3%) patients with pre- and in-hospital interventions, respectively. Analysis of drug therapy for ACS showed that aspirin was prescribed in 8 255 (98.9%), β-blockers in 7 671 (91.9%), and statins in 8 138 (97.5%) cases. Life-threatening complications occurred in 1 out of 3 patients with STEACS and 1 out of 7 patients with NSTE-ACS. Cardiac arrest (p 0.0001), myocardial rupture (p=0.001), arrhythmias (p 0.0001), and cardiogenic shock (p 0.0001) were significantly more common in patients with STEACS, and pulmonary edema (p=0.005) was significantly more common in patients with NSTE-ACS. Hospital mortality was significantly higher in STEACS patients (p 0.0001).
The most common ACS outcome was myocardial infarction (2 955 (35.4%) patients with Q-wave MI and 2 045 (24.5%) patients with non-Q-wave MI). Unstable angina was diagnosed in 1 569 (18.8%) patients.
CONCLUSION: Fifteen-year register data showed a high percentage of reperfusion interventions for ACS and prescription of drugs that improve the prognosis. A high percentage of life-threatening complications was noted, especially in STEACS; however, hospital mortality is low if proper treatment is provided.
Prospects of oral anticoagulant therapy in patients with atrial fibrillation and chronic anemia: a narrative review
Authors: Degtyareva Tatyana S. , Pereverzeva Kristina G. , Yakushin Sergey S. , Peregudova Natalia N.
Published: January 2025

Anticoagulant therapy for atrial fibrillation (AF) plays an important role in preventing thromboembolic events. This review discusses anticoagulant therapy in patients with AF and chronic anemia of varying severity. The search was carried out in PubMed and Library electronic databases from 2010 to 2023. Based on the analysis of full text literature, the authors concluded that currently oral anticoagulants in patients with AF and mild chronic anemia (Hb 90 g/L) and, according to some studies, in patients with moderate anemia (Hb 80 g/L) are considered reasonable. Patients with AF and moderate anemia (Hb 71–80 g/L) require an individualized approach to therapy with oral anticoagulants, since its benefit is not obvious in this subgroup, and the risk of hemorrhagic complications is high. Currently, severe anemia is a contraindication to oral anticoagulants in patients with AF.

Published: January 2025

Physical activity (PA) is an important component of secondary prevention of cardiovascular diseases. PA has a cardioprotective effect and improves the prognosis. Increased PA is associated with a lower coronary risk and decreased overall mortality in patients with a history of myocardial infarction. However, optimal PA achieved during cardiac rehabilitation gradually decreases afterward. Various strategies, including motivational, are used to maintain patients’ PA after cardiac rehabilitation program. Remote rehabilitation using modern digital technologies is also becoming more popular. This literature review discusses studies of the effectiveness of various measures to improve and maintain PA in cardiac patients, provides theoretical and practical considerations, and identifies topics for further researches.

When power is exercised, it results in political behavior in organizations. Excessively held organizational politics can hurt an organization and its members though some consider wisely used political behavior as positive. This study was conducted at Wolaita Sodo Polytechnic College (WSPTC) to investigate the effect of power and political dynamism on employee job satisfaction. Cross-sectional survey design was used to collect data from stratified, randomly selected 146 informants. The Rahim Leader Power Inventory (RLPI), Interpersonal Power Inventory (IPI), Perception of Organizational Politics (POP), and Minnesota Satisfaction Questionnaire (MSQ) were employed to collect data. Descriptive and inferential statistical analyses were made using statistical packages (SPSS version 23). The findings revealed that when managers legitimate, coercive, and reward power bases are higher, then organizational politics becomes higher. Power concentration at higher positions results in increased organizational politics than when it was shared. Regression analysis uncovered that 47% (R-squared 0.468) of variations in job satisfaction were explained by POP and power dynamics. Hence, it is recommended that having power sharing, empowering subordinates, and moderate political maneuvering in the use of power and politics will be helpful in maintaining constructive relationships and job satisfaction.

Cynonyms of the space squad
Authors: Ostroverkhaia I. V.
Published: January 2025

The current paper introduces a certain layer of zoonyms, including the proper names of mongrel dogs participating in the Soviet Space Programme (1950–1960-ies), into scientific circulation. The study is aimed at recreating the onomastic portrait of the space squad cynonyms. The research corpus consists of 76 cynonyms obtained from documentary sources, scientific and popular science articles, and Internet publications applying a continuous sampling method. Examination of empirical material is carried out by general scientific methods (analysis, comparison, generalization, observation) and a descriptive method involving quantitative calculations. Derivational peculiarities of cynonyms are determined through morphemic and word-formation analysis. The study reveals the main onomastic characteristics of the space squad cynonyms: predominant object-evaluative motivation actualising the dogs-cosmonauts’ external features, behaviour and participation in the space mission; predominance of Russian folk onyms built according to characteristic Russian nominative models; pronounced manifestation of the appellative onymization process resulting in extremely frequent appellative substantives and adjective names formed by direct and associative methods of nomination; presence of transonymization onyms formed in a symbolic way through intercategorial and intraspecific transonymization; prevailing diminutivity, which determines the meliorative evaluation of referents by nominators; memorability explicated through memorial cynonyms with a numerical indicator; presence of single occasional cynonyms, which turn to be a symptomatic manifestation of the nominators’ onomastic creativity; polyonymy due to extralinguistic factors. It is concluded that the cynonyms of the space squad represent a unique scientific, cultural and historical onomasticon, which has significant information potential that reveals the peculiarities of the Russian linguistic world picture. The practical significance of the study is determined by the possibility of using its materials and conclusions to cultivate a stable civic and patriotic position among our country’s younger generation with the help of onomastic means. Further prospects lie in the study of other cultural and historical zoonymic onomasticons.

It generates a large number of inconvenient private questions. In this article, a set of tactics included in the strategy of privacy invasion is described with the help of contextual analysis. Three types of invasion tactics are distinguished: preparing tactics, tactics of direct invasion and tactics of insisting on the answer on the basis of such parameters as a position in dialogue (initiating and reactional) and the contribution to the achievement of communicative aim (main and additional). Illocutionary characteristics (form of interrogation, suggestion, request and representation) and typical means of verbalization are established for each type of the mentioned tactics. Various degree of representation in dialogue of the specified tactics allows to single out two main types of privacy invasion: marked and unmarked.
In the beginning of linguogeography of the Middle Volga Region: scientific contribution of professor E.S. Skoblikova (on the 100th anniversary of the Samara scientist)
Authors: Bazhenova T. E.
Published: January 2025

The article assesses the scientific contribution of a prominent representative of the Samara Linguistic School, Professor of Samara State University Elena Sergeevna Skoblikova to the study of the dialects of the Middle Volga region. Her passion for dialectology provided her with her first successful steps into big science and remained throughout her subsequent scientific activity. For many years, she was a participant and organizer of dialectological expeditions to study the dialects of Penza, Ulyanovsk, Samara and Orenburg regions. In the late 1940-ies, even before the appearance of generalizing works on linguistic geography, E.S. Skoblikova in her Ph.D. thesis described the patterns in the geographical distribution of the features of dialectal forms of personal pronouns in the dialects of the vast territory of the European part of Russia. A number of her articles highlight the functioning and history of formation of the features of dialectal vocalism, which are important from the point of view of the typology of the Volga dialects. In the works of E.S. Skoblikova, the basis for the classification of Middle Russian dialects and methods for determining the genesis of secondary dialects is laid, taking into account linguogeographical data on phonetic and morphological features. Her scientific research in dialectology is characterized by attention to the synchrony and diachrony of linguistic processes in dialects, the study of individual links of dialect systems in connection with the system of the Russian language as a whole. The results of E.S. Skoblikova's dialectological research contributed to the clarification of the regional picture of the dialect landscape in the Middle Volga region. The attempt to analyze the scientific heritage of E.S. Skoblikova is interesting and significant both in terms of linguistic historiography and in terms of analyzing the achievements of regional dialectology and the entire Russian linguogeography.

This article presents the opinions of a number of leading Russian researchers, the subject of discussion of whom were the provisions expressed by Doctor of Historical Sciences, Professor V.V. Babashkin and Candidate of Historical Sciences, Associate Professor S.I. Tolstov. The authors of the article «Collectivization as a page of history and its place in the national ideology of modern Russia» published in the previous issue of the journal focused their attention on studying the formation of the «Soviet» version of collectivization of the peasant village. Based on the concept that the national ideology of the modern Russian Federation should be based on adequate ideas about the main events of the Soviet period, they come to the conclusion that it was peasant studies that should have become one of the most significant tools for historical and sociological research into the history of the country. The vivid and polemical presentation of the material and the undoubted demand in such a series of publications aroused the active interest of a number of well-known historians, primarily those involved in agrarian issues. Despite a number of serious critical comments during the exchange of opinions, the majority of researchers participating in the discussion recognized the significance and urgency of raising such issues and the need to develop a specific position for the development of modern historical science
