Authors: Tsvetkov Alexander S. , Buymova Svetlana A. , Bubnov Andrey G.
Published: December 2024

It is known that the quality of drinking water has a strong impact on the health of modern people. This largely depends on the chemical and microbiological composition of the water consumed. At present, there is no established list of marker indicators to enable conclusions to be drawn about the safety of drinking water from a range of different sources in a minimum timeframe. The paper presents the results of chemical and microbiological analysis of water samples from vending machines of various brands and springs located in the city of Ivanovo and the Ivanovo region. The results show the non-compliance of these types of water with established standards for the period of study under consideration. In the course of identifying marker substances based on the data obtained, regression and correlation analyzes were carried out to characterize the chemical composition of water from the proposed sources. Processing of the obtained dependencies of the content of a particular pollutant on time for springs was carried out by polynomials of the 8th and 9th orders, and for vending machines - by polynomials of the 3rd and 4th orders. Trend equations for these dependencies were also obtained.  Conclusions are drawn about the possibility of using the statistical processing methods under consideration, the presence or absence of a stochastic relationship between all analyzed components is determined, a list of indicators is presented, between which it is possible to trace the interdependence of content in the types of water under consideration. The list of chemical substances that can be considered as marker indicators for water from water mats and springs is given, as well as the maximum permissible concentrations of the proposed substances.

Authors: Ivanov Konstantin V. , Filimonova Yuliya A. , Agafonov Alexandr V. , Nazarov Sergey B.
Published: December 2024

The development of the field of application of ceramic nanomaterials for medicine has recently been of significant interest. These include nanodispersed barium titanate powders, which exhibit antimicrobial and antifungal activity. They are considered as carriers of drugs, as well as biocompatible components of bone tissue. The search for new opportunities to realize the potential of nanodispersed barium titanate in biomedicine is an urgent task. The paper presents a method for the synthesis of nanosized barium titanate powder obtained by heat treatment at 800 °C in an air environment of sol-gel synthesis products. The resulting nanomaterial has a crystalline structure with cubic structure. According to electron microscopy, the powder particles are characterized by a polydisperse composition and are partially agglomerated. The results of energy dispersive analysis of the samples are presented. The particle size in the dispersion ranges from 50 nm to 250 nm, and the Scherrer crystallite size is 3.85 nm. The degree of hemolysis was assessed in vitro using fresh donor blood in the presence and absence of barium titanate nanoparticles. The hemolytic effect of barium titanate (>5%) manifests itself at a high concentration of powder (450 µl/ml) in the blood, which indicates the biocompatibility of nano-sized BaTiO3 up to the specified concentration. The effect of BaTiO3 concentration on free radical oxidation of lipids and antioxidant activity in blood serum was analyzed using the method of induced chemiluminescence. It has been established that at a concentration of 200 µl/ml BaTiO3 exhibits antioxidant activity, and at 400 µl/ml it has the ability to activate free radical oxidation of blood serum lipids.

PLASMA PARAMETERS AND REACTIVE-ION ETCHING KINETICS OF ZnO IN HYDROGEN BROMIDE: THE INFLUENCE OF INERT CARRIER GAS
Authors: Efremov Alexander M. , Smirnov Sergey A. , Betelin Vladimir B. , Kwon Kwang-Ho
Published: December 2024

This work discusses the influence of inert carrier gases, Ar and He, on both gas-phase plasma characteristics and ZnO etching rate under typical reactive-ion etching conditions in the hydrogen bromide environment. Plasma diagnostics by Langmuir probes and 0-dimensional plasma modeling allowed one to compare how the content of given carrier gas does influence electrons-and ions-related plasma parameters, kinetics and densities of plasma active species. It was found that the transition toward Ar- or He-rich plasmas a) causes the growth of electron temperature (due to lower electron energy losses in collisions with atomic species); b) reduces plasma electronegativity; and c) results in opposite changes in both ion density and ion flux. The last phenomenon is due to opposite changes in total ionization rates determined by sufficient difference in ionization rate coefficients for Ar and He atoms. Important features of HBr + Ar plasma at 0–80% Ar are also the slower-than-linear fall of Br atom density (due to the intensification of electron impact dissociation for both HBr and Br2 molecules) as well as an increase in H atom density (due to decreasing their loss rate in gas-phase reactions). Etching experiments indicated that the ZnO etching rate is mostly contributed by the ion-assisted chemical reaction while the reaction rate decreases faster compare with the Br atom flux. The corresponding decrease in the effective reaction probability may be related to changes in both ion bombardment intensity and hydrogen passivation effect.

Published: December 2024

The reactivity of various alumina precursors in the reaction of magnesia spinel formation is compared: industrial powders (corundum powder KP, alumina: metallurgical GC, non-metallurgical G-00, reactive RG) and the xerogel combustion product from aluminum nitrate with citric acid under conditions of mechanical activating treatment and without it. The infrared spectra of corundum and periclase after mechanical treatment of various types (impact-abrasion in a planetary mill, abrasion in a ball-ring mill) were analyzed. It has been found that short-term action not only activated the components, but also contributed to the destruction of adsorption compounds at the preparation stage. The effect of mechanical activation of reagents on spinel yield was analyzed. It has been established that the alumina xerogel combustion product without annealing was X-ray amorphous, which suggested its high chemical activity. When using it, a more complete binding of initial reagents into the product was found compared to a mixture of periclase and corundum. Even in the absence of mechanical activation of the components, it was possible to achieve a high spinel yield (up to 80%). The obtained values of the effective reaction rate constants indicated a greater efficiency of mechanical treatment, including an impact component, with the combined activation of periclase and corundum/alumina. Co-treatment of reagents in a planetary mill (PM) made it possible to increase the reaction rate by 6-6.5 times, while abrasion in a ball-ring mill was only 1.7 times. Pretreatment of one component of the initial mix in PM was the most expedient for periclase, since it allowed to speed up the reaction by ~ 5 times, and is also the most profitable energetically and technologically due to the treatment of only one component of reduced hardness. The use of xerogel combustion product in the spinel synthesis was very effective, because it accelerated the process by ~4 times even without preliminary activation by mechanical means.

Published: December 2024

Trade liberalization has become an integral part of economic globalization, providing both opportunities and challenges for the Micro, Small, and Medium Enterprises (MSMEs) sector in Indonesia. This study aims to analyze the impact of trade liberalization on MSMEs, including the opportunities it creates, the challenges faced, and the adaptive strategies that can be implemented. Using a qualitative approach based on literature reviews, this study explores various references related to the socio-economic impacts and policy implications for the MSME sector. The findings indicate that although trade liberalization opens broader market access and enhances innovation potential, MSMEs face significant challenges such as global competition, limited capital, and compliance with international quality standards. Therefore, inclusive policies and empowerment programs are essential to ensure MSMEs’ sustainability and equitable benefits from trade liberalization.
Examining gender and ethnic segregation in Italy’s labour market: Are women and migrants more segregated than men and natives?
Authors:   University of Rome Tor Vergata, Italy, Martini Barbara
Published: December 2024

In Italy, migration is a new phenomenon, with non-native women and men constituting roughly equal shares of the workforce. However, their employment sectors differ significantly: non-native women often work in the same sectors as native women, while non-native men are employed in distinct sectors compared to their native counterparts. This paper examines gender segregation by analysing individuals’ backgrounds—distinguishing between native and non-native workers—and the impact of contract types, specifically fixed-term versus open-ended contracts. The study aims to determine whether the prevalence of these contract types influences the level of gender segregation across sectors. Findings indicate that the type of employment contract significantly affects gender segregation. Increased use of fixed-term contracts is associated with a reduction in sectoral segregation, suggesting that women are increasingly willing to enter male-dominated fields, while men tend to gravitate towards female-dominated sectors. This dynamic underscores the complexities of gender roles within the context of migration and employment.

The nutritional value of pastures can vary depending on the type of available vegetation, its quality
and environmental conditions. The analysis of the samples was carried out in the laboratory of the Agricultural
Institute - Stara Zagora, using Infrared technology for analysis of feed and components - NIRS DS 2500
- monochromator, with a scanning range of 850 - 2500 nanometers. The following quality indicators were
determined: Dry matter, %, Protein, %, Starch, %, Ash, %, ADF, % and NDF, % to available moisture. In the
spring season, the dry matter is 23.76%, in the summer it is 29.89% and in the winter it is 68.04%. The protein
varies from 6.75% in spring to 3.64% in autumn. In the summer we find 4.77%. The content of acid detergent fiber varies from 8.25 to 35.03%, with the highest value recorded in autumn - 35.03%. The results obtained in
our study for neutral detergent fiber vary from 14.2% to 43.3% depending on the seasons. In summary, pastures
offer a rich source of nutrients for ruminants, including proteins, carbohydrates, vitamins, minerals and fiber.
Proper pasture management, such as appropriate planning, crop rotation and fertilization, can help optimize
the nutritional composition of pastures and provide optimal rations for large ruminants. The results obtained
were processed variationally - statistically using the software product SYSTAT 12 © Copyright 2007, SYSTAT
Software, Inc. All Rights Reserved and STATSOFT Statistics for Windows 10.
The aim of this study is to establish seasonal changes in the nutritional value of pasture resources for large
ruminants. Meadow and pasture production, which is used for direct consumption by animals or for obtaining
hay for manure feeding, is indirectly related to this problem.

Method: This research is fundamental in terms of its objective and descriptive-correlational in terms of data collection. The statistical population of this study consisted of all married women at the Faculty of Psychology and Educational Sciences, Islamic Azad University, Central Tehran Branch, during the academic year 2022-2023. To this end, 385 women were selected using Cochran’s formula and convenience sampling method. Participants responded to the Marital Self-Disclosure Questionnaire by Waring et al. (1998), the Ruminative Response Scale by Nolen-Hoeksema et al. (1993), and the Brief COPE Inventory by Endler and Parker (2008). After collecting the questionnaires, the data were analyzed using Pearson’s correlation coefficient and simultaneous multiple regression analysis.

Findings: The results indicated a significant negative correlation between rumination, avoidance-oriented coping strategies, and emotion-focused coping strategies with marital self-disclosure (p < .01). There was a significant positive correlation between problem-focused coping strategies and marital self-disclosure (p < .01).

Conclusion: The results of the multiple regression analysis also revealed that 71.6% of the variance in marital self-disclosure is explained by rumination and coping strategies. Therefore, it can be concluded that rumination and coping strategies can predict marital self-disclosure among married women.

Objective: The present study aimed to investigate the effectiveness of an integrated intervention combining mentalization and the training package for building a secure bond on attachment styles in spouses with insecure attachment styles.

Method: This quasi-experimental study employed a pretest-posttest design with a control group and a two-month follow-up. The statistical population consisted of couples who had sought services from counseling and psychology centers in northern Tehran under the supervision of the Iranian Organization of Psychology and Counseling in 2022 and who were in the first five years of their marital life. Based on the inclusion criteria, 24 couples with insecure attachment styles were identified and randomly assigned to either the experimental or control group. The intervention was implemented over 12 sessions, with weekly two-hour training sessions for the experimental group. Data were collected using the Attachment Styles Questionnaire (Bartholomew & Horowitz, 1991). The data were analyzed using mixed ANOVA with one within-subject factor (time) and one between-subject factor (experimental and control groups), Bonferroni post hoc test, and SPSS software version 25.

Findings: The findings of this study indicated that the integrated intervention of mentalization and the training package for building a secure bond had a significant and positive effect on the attachment styles of couples (p < .01), and the effects were sustained after a two-month follow-up.

Conclusion: Based on the obtained results, couples' therapists can use the integrated intervention of mentalization and building a secure bond to optimize attachment styles in couples with insecure attachment styles who are in the early years of their marital life.

Authors: Nargesi Khoramabad Nasrin , Shiri Tahmures , Ali Mohseni Reza
Published: December 2024

Objective: This study aims to conduct a sociological examination comparing the social dimensions of employment in two vulnerable groups: female heads of households and individuals with disabilities.

Methods and Materials: The present research is applied in terms of its objective and has been conducted using a quantitative survey method. Data were collected through a researcher-made questionnaire, which was utilized after confirming its validity and reliability. The statistical population included beneficiaries under the nationwide welfare organization, with a sample population consisting of 384 individuals with disabilities and 384 female heads of households under the welfare organization’s coverage. Respondents were selected based on random sampling. Data analysis was performed using SPSS software.

Findings: The results from the Mann-Whitney U test indicated that overall, there is no significant difference between the employment of female heads of households and individuals with disabilities (U = 68402.500, p = 0.083) in terms of social dimensions. This means that, from a social perspective, the two groups face similar challenges. Additionally, examining the social components of employment revealed significant differences between the two groups in the components of role performance, social support, individual/social rights, and employment barriers. However, in terms of the job security component (U = 70140.500, p = 0.238), there is no significant difference between these two vulnerable groups. Both groups, individuals with disabilities and female heads of households, lack job security.

Conclusion: Attention to the social dimensions of employment for these two vulnerable groups by relevant organizations, especially in establishing job security for them, is essential and requires increased focus.
Tone Alternation, Polarity, and Down-stepping Influences in Four Noun Categories in Lama
Authors: Yanting Sun
Published: December 2024

The Lama language, spoken in Togo, West Africa, belongs to the Gur language family. Linguistic studies on Lama‘s tonal system, particularly within the generative grammar framework, remain limited. This study presents a detailed analysis of the tonal rules in Lama, focusing specifically on noun morphology. A comparative analysis of four noun categories reveals: (a) the categories exhibit three surface tone patterns (high-level, low-level, and falling) in isolation; (b) within phrases, the Low Tone Deletion Rule polarises the categories to two tones, retaining only high-level and low-level tones, as falling tones are blocked in this context; (c) tone alternation is governed by the High Tone Spread Rule; (d) while the underlying tones correspond to surface tones in the first three categories, the fourth category’s underlying rising LH sequence never surfaces and is simplified to a low-level tone via the Contour Tone Simplification Rule; and (e) the phenomenon of downstep arises from the interaction of the High Tone Spread, Low Tone Deletion, and Contour Tone Simplification rules.

Authors: da Silveira Yassu Alexandre Mitsuro
Published: December 2024

A recente intensificação das queimadas na floresta Amazônica explicitam uma face do neoextrativismo no Brasil. O país parece repetir o Consenso das Commodities que atravessa toda a América Latina. A desindustrialização em curso desde os anos 1980 combinada com a expansão das atividades extrativas, minerais e agrícolas alavancaram a reprimarização da economia brasileira, que desde então vêm conduzindo a uma reestruturação do espaço nacional. Neste trabalho dedico-me a analisar as formas de provisão de infraestrutura logística, no contexto de privatização, financeirização e desnacionalização do setor. Desse modo, pretendo avançar na compreensão das transformações sócio espaciais em curso, com foco na região Centro Oeste do país, a partir das concessões da rodovia BR 163 e do projeto da ferrovia EC-170- Ferrogrão.

Published: December 2024

This paper delves into the tools developed on the CIT Polyhedron platform, particularly in the context of scientific applications, with a comprehensive exploration of the consolidation and structuring of informational resources. Central to this is the use of ontological systems, where ontological engineering plays a pivotal role in creating structured knowledge systems that effectively represent and interact with various information resources. The paper particularly emphasizes narrative ontology, aunique methodology for organizing and assembling information across multiple disciplines, enhancing the richness and coherence of knowledge.A substantial portion of the study is dedicated to describing how to structure scientific studies using an IMRAD-based ontological structure. This innovative approach aims to facilitate the organization, retrieval, and comprehension of scientific data. The ontology is crafted to encapsulate the essence of scientific papers, covering objectives, methodologies, findings, and discussions. This systematization is especially crucial within a centralized, web-oriented educational framework, ensuring a seamless flow of knowledge and interoperability between different systems.The paper also presents methods for representing and assessing information from scientific and educational organizations. This is achieved through a general ontology divided into several ontologies to address these organizations’ various aspects and performance indicators. “Polyhedron Researcher”, described in the paper, is a novel platform for systemizing scientific data. This platform is based on the Polyhedron model and focuses on adapting and optimizing the processes of scientific researchand data management. It integrates cognitive services for information analysis and employs interactive documents for data representation. The platform is tailored to support researchers, aiding them in organizing their scientific activities and creating publications. This transdisciplinary approach supports various scientific and research activities and promotes efficient data management and knowledge dissemination in the scientific community.

It consisted of (41) paragraphs distributed over three dimensions: The first dimension: includes the nature and causes of dyslexia. The second dimension: includes the diagnosis and symptoms of dyslexia. The third dimension: includes therapeutic interventions for dyslexia. The researchers verified the validity and reliability of the scale. The results showed that the competencies of Jordanian teachers of the first three grades in dealing with students with dyslexia were average across the scale dimensions as a whole, with the “diagnostic competencies” dimension ranking first, followed by the “nature and causes of dyslexia” dimension in second place, and the “treatment of dyslexia” dimension in last place. The results also indicated that there were statistically significant differences in the competencies of teachers of the first three grades according to the variable of teaching experience, and the differences were in favor of those with experience ranging between (6 years and less than 11 years). As for the variable of grades (first, second, third) taught by primary school teachers, the differences were in favor of teachers of the first grade, followed by the third grade and then the second grade. As for the variable of attending training courses, the differences were in favor of teachers of the first three grades who attended previous training courses in dyslexia. In light of these results, a set of recommendations were presented.

This study aims to use the hand-painting method in designing and fabricating a metamaterial based on a circular shape that exhibits a negative refractive index over the microwave spectrum. Hand painting is a simple and inexpensive fabrication method. This study applies silver ink as a periodic conductor to glossy paper as the dielectric substrate. The spectrum of investigation in this study is 3–6 GHz, and the experiment results are compared with the simulation results. The slight error obtained between transmission results from the simulation and the experiments reflects limitations in the fabrication methods used. Overall, the experiment results have a similar trend to the simulation results. The electrical properties of the metamaterial are retrieved from the transmission and reflection simulation results. The simulation results are employed instead of the experimental results because of the fluctuating data provided by the latter. The refractive index presents a negative value at 3–3.6 GHz.

The rapid advancement in the industrial sector, particularly within the textile industry, necessitates the use of colorants for fabric processing, with methylene blue being a predominant choice. However, the improper disposal of methylene blue dyes can lead to significant environmental hazards, underscoring the need for effective treatment methods before release into ecosystems. This study explores electrocoagulation, an innovative treatment technique powered by electrical energy, as a potential solution for mitigating the environmental impact of methylene blue in textile wastewater. The research investigates the efficiency of the electrocoagulation process using iron (Fe) and copper (Cu) electrodes under various operational conditions, including electrode spacing (1, 1.5, and 2 cm), applied voltage (15, 20, and 24 volts), and electrode contact time (5, 10, 15, 20, 30, and 60 minutes). The findings reveal that the electrocoagulation method achieves an optimal methylene blue removal efficiency of 99% under specific conditions: an electrode distance of 1.5 cm, an applied voltage of 24 volts, and a contact duration of 30 minutes. This research underscores the potential of electrocoagulation as an efficient and environmentally friendly approach for the treatment of textile wastewater, contributing to the sustainable management of industrial effluents.
