‘Demographic’ factor of fertility: Assessing territorial potential on the example of the Nizhny Novgorod region
Authors: Egorova Nadezhda , Sitnikova Irina 
Published: September 2024

Introduction. Despite the implementation of serious measures in the framework of state family policy to stabilise the demographic situation, it remains difficult in most regions. This is due, firstly, to the new challenges the country is facing, and secondly, to the complexity of the very processes that need to be controlled. Population size, being a complex quantitative indicator of the stability of society, is determined by a number of demographic processes, among which fertility remains the main one. The number of studies attempting to identify the factors determining fertility trends is growing. All of them demonstrate the complexity and multifactorial nature of the process and the changes taking place. More and more often attention is paid to the demographic characteristics (sex-age and marriage structure) of the population as a starting point from which to begin the assessment of the territory and its reproductive potential.Nizhny Novgorod region, being a typical Russian region, has been demonstrating an unfavourable scenario of demographic situation development in recent decades. The article attempts to describe and assess the reproductive potential of the region, to identify the possibilities and limitations of fertility growth in the current conditions, based on the analysis of the ‘demographic’ factor.Materials and methods. The analysis and conclusions are based on the data of the Federal State Statistics Service on demographic processes in Russia and the region for 1990-2023 (population size, birth rate, marriage rate, divorce rate), as well as on the data of regional sociological studies on fertility and family/reproductive behaviour.Results and discussion. The results of the study provide little basis for a favourable forecast in the region. On the one hand, the sex and age structure of the population is not yet characterised by disproportion in fertile ages, except for the oldest groups. However, there is a high probability of its appearance in younger ages under current conditions. In addition, active and potential fertile groups of women are significantly smaller than older groups. The marriage structure is becoming more stable, but with a high probability of divorce, acceptability of cohabitation, and a shift of births to older groups. The studies record a persistent gap between the desired and actual number of children in different socio-demographic groups, which, from the authors' point of view, is important and requires careful research to correctly stimulate fertility.

Authors: Moreno Navarro Ángel , Martínez Ortega Ma. de los Ángeles , Martínez Ortega Minerva 
Published: September 2024

En los inicios de la Ciudad de México (CDMX) su configuración territorial fue delimitada por elementos físicos naturales o por el señalamiento limítrofe a través de mojoneras, las cuales son monolitos de piedra. Con el crecimiento poblacional, la gente se fue estableciendo en los límites de la CDMX modificando la configuración territorial planeada en los inicios de esta. Existen por otro lado, factores políticos como la configuración de los distritos electorales que generaron otro nuevo límite, esto trajo problemas graves a la población ya que se presentó una dualidad en su delimitación y definición territorial, (por un lado, ser de la CDMX y por otro del Estado de México). Se partió del supuesto hipotético que la falta de claridad en la delimitación territorial de algunas comunidades y la conformación de los distritos electorales por el Instituto Nacional Electoral (INE), generaron una doble división política. El objetivo de este trabajo fue identificar la importancia de la aplicación de la planeación urbana y de una clara delimitación territorial, a través de la detección de mojoneras. Además del señalamiento del impacto provocado en la comunidad estudiada, así como algunas condiciones que repercutieron directamente.
Esta investigación es mixta (cuantitativo-cualitativa) por un lado se realizó la identificación de los límites territoriales definidos en la “Ley del Territorio de la CDMX” a través de la ubicación de las mojoneras, contrastando con los límites de la cartografía del padrón electoral del INE, mostrando una dualidad territorial, tal y como se señaló en la hipótesis. Una vez encontrada la diferencia, se pudieron mostrar algunas consecuencias muy negativas para la población estudiada. Se detectó que los predios afectados por esta dualidad, presentan problemas puntuales al no contar con los servicios básicos; así como, de identidad, al estar en los límites de una alcaldía y un municipio a nivel estatal.

Published: October 2024

Abstract
As an important cultural institution for urban cultural inheritance and construction, the complementarity, interaction, and development between university culture and urban culture are also getting more and more attention. This study analyzes the dynamic mechanism of the integration of university culture and urban culture by combining the dynamics model. Then, it constructs a dynamics model for the integration of urban culture into university culture based on the group dynamics theory and the airplane dynamics model. Then, a data-driven decision-making optimization scheme is proposed based on the BASM model, and a data-driven decision-making model oriented to the development of cultural integration is constructed with the data related to the artistic integration of universities as the driving basis. Finally, an empirical analysis of the integration development of culture between University M culture and Guangzhou city culture is carried out in Guangzhou city as an example, with a comprehensive average score of 92.70 for cultural recognition, and the correlation coefficients of the dimensions are highly correlated between 0.812 and 0.891. Meanwhile, the regression coefficients corresponding to the seven dimensions of cultural integration and development are all less than 0.05, and the VIF values are all less than 10. Moreover, the comprehensive average score of each dimension after optimization is 4.193, which is 0.79 points higher compared with that before optimization, and the satisfaction level is 1.297 points higher. In this paper, the optimization of the development strategy for the integration of university culture and urban culture can promote cultural integration and provide a specific optimization path for the integration of university culture and urban culture.

Abstract
Currently, the implementation of a coal mine production safety monitoring system, capable of real-time monitoring of the safety condition of large coal mine equipment and timely dispatch management, is crucial for the efficient and safe operation of coal mine enterprises. This paper designs the coal mine major equipment failure process based on the rolling bearing’s vibration mechanism, analyzes the major equipment’s failure signal using both time domain and frequency domain analysis methods, and employs the intelligent fuzzy control method to identify the major equipment failure. We have designed and practically applied a real-time, multi-threaded, and comprehensive fault diagnosis and prediction system for coal mine major equipment, combining information from coal mine safety, production, and operation. The results show that the normal state’s time-domain amplitude approximates (-0.2, 0.2), and the time-domain waveforms all display periodic shock signals when the bearing sustains damage. The faulty vibration amplitude of the inner ring is within 0.08 ms
2 and the faulty vibration amplitude of the outer ring is within 0.44 ms
2, and the diagnostic accuracy using the method of this paper reaches 97.2%. This study demonstrates the effectiveness of remote monitoring and fault analysis of major equipment in coal mines, which effectively improves the equipment start-up rate and ensures coal mine production safety.

Abstract
This paper analyzes the engineering characteristics of loess and the factors affecting wet subsidence, briefly outlines the application effect of PP modular cisterns, and combines the two to design a PP modular cistern based on rainwater harvesting. Combined with the analysis of the pre-engineering conditions of the storage tank, propose the treatment method for wet subsidence loess foundations. Design the structure of the storage tank by determining the volume of the tank by comparing the difference between the inlet and outlet flow during the storage time integral. Simulate the modeling of storm floods and the process of emptying stormwater regulating ponds. Evaluate the geologic conditions for the construction of the regulating pond project. Compare the original investigation report with the results of this paper’s test of the engineering foundation’s wet subsidence coefficient. Set different thicknesses of bedding layers and calculate the settlement of the center of the pool under different humidity levels of the loess layer. Simulate the 2.3-hour rainstorm process, analyze the storage volume of the storage pond during the period, and calculate the cumulative storage volume of the storage pond. This project’s foundation loess wet subsidence coefficient is medium, and the actual additional pressure is much smaller than the starting pressure of wet subsidence. It is appropriate to use the soil bedding program (1.6m plain soil bedding layer and then rammed 0.4m thick 2:8 gray soil, with PP module seepage control). Combined with the local hydrological conditions, it is known that the peak present time of the peak outflow from the regulating pond T
P =85min, and the volume of the regulating pond is 22543.47 m

Authors: Hamed Zena Sattam , Shaban Khalid Ahmed , Faris Ghada Abdul-Munem 
Published: October 2024

Abstract
Combining analgesic medications with distinct pharmacodynamics may result in effective analgesia and reduced adverse effects by lowering dosages of one or both medications. The objective was to investigate the nature of interactions of metoclopramide and metamizole by measuring the antinociceptive and neurobehavioral effects in mice. The drugs were administered intraperitoneally (ip) in mice. The antinociceptive effect was determined by the up-and-down method. Isobolographic analysis was performed by simultaneous injection of the two drugs at ED50 ratios of 1:1 and 0.5:0.5. The treated mice were also subjected to an open-field behavioral test as well as dorsal immobility and negative geotaxis behavioral paradigms. The ED50 of metoclopramide and metamizole were 33.71 and 43 mg/kg ip, respectively. Lower ED50 was established for metoclopramide and metamizole by 48.44% and 47.49%, respectively when given at a ratio of 0.5:0.5, and by 35.81% and 29.88%, respectively at a ratio of 1:1. The combined dose of metoclopramide and metamizole (8 and 10 mg/kg, ip, respectively) significantly decreased the open field-activity test in mice. This was observed by lower number of squares crossing compared to the control. Additionally, the drug combination resulted in a substantial increase in the duration of dorsal immobility response and delayed the negative geotaxis task when compared with the control group. The results indicated that the interaction between metoclopramide and metamizole in lower dose ratio with ED50 50:50, was synergistic in producing analgesia in mice with reduced risk for adverse reaction but with decreased behavioral and motor neuronal activity.

Published: October 2024

Background: Root canal treatment is an effort to maintain the function and aesthetics of teeth. The smear layer is formed from the remains of instrumentation composed of organic and inorganic components. A smear layer in the tooth root canal will benefit the adhesion and colonization of microorganisms, block the action of disinfectant solutions, and prevent medicaments in the tooth root canal from penetrating the dentin tubules in the tooth root canal walls. Irrigation can be used for cleaning and disinfection in areas of the root canal that cannot be reached using instruments. Starfruit contains alkoloids, saponins, tannins, flavonoids, phenols, and triterpenoids. Objective: To determine the effectiveness of star fruit extract (Averrhoa bilimbi L) as a smear layer cleaning agent. Materials and Methods: This researcher used laboratory or experimental testing called Post Test Only Control Design. Samples were taken using the purposive sampling technique involving four treatments and six repetitions. The statistical test used is the Mann-Whiteney test. Results: Based on the Mann-Whiteney test, the test results obtained a p-value of 0.093 which is more significant than 0.05 (p-value 0.05). The results showed no significant difference between the 17% EDTA and 35% extract treatment groups regarding smear layer cleanliness. The 35% extract group is as good as the 17% EDTA group. Conclusion: star fruit extract (Averrhoa bilimbi L) is 35% effective in cleaning the smear layer.
Background of Environmental Awareness and Pro-Environmental Behavior Among Amazonian Farmers - Emphasis on the State of Rondônia
Authors: Ferreira Joélica Fernanda da Silva , Herrmann Felipe Fehlberg , Canever Mario Duarte 
Published: October 2024

Objective: The study aims to identify levels of environmental knowledge, environmental beliefs, environmental awareness, and sustainable practices among Amazonian farmers, associating these factors with socioeconomic and demographic characteristics.

Theoretical Framework: Environmental awareness is the understanding of the importance of protecting the environment and promoting sustainability, influenced by backgrounds such as environmental knowledge and beliefs, and social and income factors, resulting in pro-environmental behaviors.

Method: Interviews with 308 farmers from the central region of Rondônia assessed socioeconomic and demographic characteristics, environmental knowledge, environmental beliefs, environmental awareness, and sustainable agricultural practices. Quantitative analysis used t-tests and analysis of variance to identify significant differences between categories such as age, gender, property size, and education.

Results and Discussion: Although it was expected that environmental components would be crucial for sustainable rural development, the variation between groups was small. Environmental awareness was positively associated with education and property size. Higher education expanded environmental understanding and the adoption of sustainable practices. Surprisingly, larger properties, despite focusing on profit maximization, showed greater environmental awareness. Female-led properties had lower adoption of sustainable practices, possibly due to reduced access to resources and support networks.

Research Implications: Despite assumptions that environmental dimensions would be strongly associated with socioeconomic and demographic characteristics, little variation was observed, indicating increasing uniformity in environmental awareness among farmers.

Originality/Value: Understanding the environmental awareness of farmers in the Amazon is crucial for developing effective conservation strategies. Direct research with these often-overlooked farmers can provide valuable insights for public policies and environmental education, promoting sustainable agricultural practices and forest preservation.

Influence of Walking Modification Strategies on Frontal Plane Hip Joint Moment and Gait Naturalness in Healthy Adults
Authors: Subasinghe Arachchige Ransi S.S. , Young Jasmin , Cheung Roy T.H. 
Published: October 2024

OBJECTIVE: To evaluate the effects of lateral trunk lean and step width modification on hip adduction moment in healthy participants and examine their influence on walking naturalness. METHODS: Ten healthy participants underwent gait analysis under 4 walking conditions: natural walking, large trunk lean, doubled step width, and combined modification with slight trunk lean and 1.5 times step width. Early stance and late stance hip adduction moment were analyzed and compared using repeated-measures analysis of variance. Subjective naturalness of gait was also recorded. RESULTS: We observed a significant effect of walking condition on the hip adduction moment during early stance (F3,36 = 6.665, P = .001) and gait naturalness (F3,36 = 30.519, P<.001), but not hip adduction moment during late stance ( P = .733). Pairwise comparison indicated significantly reduced hip adduction moment during early stance with large trunk lean when compared to natural walking (36.7% less, P = .002, Cohen’s d = −1.41). Both combined and doubled step width modifications did not yield the expected hip adduction moment reduction ( P>.296). The perceived naturalness of the doubled step width modification was most comparable to natural walking ( P = .529), while the trunk lean modification was significantly less natural than natural walking and the least natural modification overall (81.1% less, P<.001, Cohen’s d = −4.34). CONCLUSION: Although trunk lean modification effectively reduces hip joint loading, it is perceived as the least natural pattern. Step width was more challenging to modify than trunk lean.

Dostoevskij: l’altro ritratto Contributi della Scrittura Letteraria alla Linguistica, all’Estetica, alla filosofia e alla psicologia del linguaggio
Authors: Ponzio Luciano 
Published: October 2024

L'opera di Dostoevskij ha giocato un ruolo decisivo non solo in ambito letterario, ma anche nella Filosofia e Psicologia del Linguaggio, nell’Estetica, nella Linguistica e nella Semiotica ampliando la comprensione di concetti fondamenti: enunciazione, discorso interiore, romanzo polifonico, discorso libero indiretto, dialogismo, alterità, autore/eroe, cronotopo, straniamento, exotopia, incompibilità, generi discorsivi, testo, segno e ideologia, ecc.. Questi concetti legano le ricerche di diversi autori: tanto di Bachtin e del suo circolo, di Vygotsky, dei "formalisti" e della “Scuola di Praga” che mantennero vivo il rapporto tra Linguistica e Letteratura (tradizione ripresa nella scuola Mosca-Tartu da Uspenskij-Lotman); quanto di quegli autori che diffusero la Letteratura Russa in Francia (Todorov/Kristeva).
