It is a challenge to determine the active part of a solid phase in chemical process when the purity of the aforesaid is not sufficient and could jeopardize the solid real applications. CuAl LDH phase has been obtained with low percentage of impurities and the intention to use it as photoreduction or photoxidation catalyst and /or templating agent in the design of nanohybrid composites photocatalysts, for CO2 storage that could facilitate its later abatement and/or highly efficient semiconductor material. A set of synthesis were implemented with a mixture of Cu(NO3)22.5H2O and Al(NO3)3.9H2O with Na2CO3 and NaOH using coprecipitation at variable pH. Keeping constant a low CO32-/Cu2+ + Al3+ fraction in all sets, constant basic pH and ageing time (96h) with slight variations in T, resulted in mixed phases of malachite, CuAl LDH and traces of Cu(OH)2. At basic pH and T with different ageing time, similar XRD patterns were measured with noticeable differences, though. When the carbonate ratio, ageing time, and pH were constant (7.50, 96 h, 9.24), modest changes in T generated key dissimilitude in the diffractograms. The resulting band gap energy of this LDH coincided with the visible spectral region energy. A more precise tuning of variables has led to a high degree of optimization of the CuAl LDH and further contributes to comprehend how varied synthesis conditions influence this metastable hydrotalcite Obtention.

Authors: Najim Rayhana S. , Risan Mohsen Hashem , Al-Ugaili Dhafar Najim
Published: September 2024

Background: The bad administration of antibiotics represents a worldwide health issue as it leads to the emergence of multidrug-resistant microbes including Staphylococcus aureus, which represents a significant challenge for public health since it increases its ability to cause potentially fatal infections. Objective: This study aims to reduce the bacterium’s ability to form biofilms and antibiotic resistance. Methods: Thirty Staphylococcus aureus isolates were isolated from different clinical samples in Baghdad city and their ability to form biofilm was tested using the Microtiter Plate method. Out of 30 isolates, eight strong biofilm producer isolates were further investigated for their antimicrobial activity and biofilm formation with the impact of quercetin. Results: The results showed the ability of quercetin to inhibit bacteria and had an antibiofilm activity that was determined through investigation of the minimal inhibitory concentration by taking different concentrations. The anti-biofilm activity of quercetin was determined for the eight isolates and the results showed that biofilm formation was reduced by 100% using quercetin at a concentration of 3.1 mg/ml. Conclusions: Quercetin represents a suitable alternative to synthetic antimicrobials with the increased rate of drug-resistant bacteria among clinical samples with highly effective ability as anti-biofilm formation among strong biofilm producers of S. aureus.

In this study, a new method of choosing classical empirical equations for calculating heat transfer coefficients in the tubes of a shell-and-tube heat exchanger in the transient mode is proposed. This method is based on the fact that the flow is structured into a laminar boundary layer (LBL) zone and a turbulized part, and the heat transfer coefficient is calculated through the transient and turbulent heat conductivity, as well as the average thickness of the LBL and, accordingly, the average thickness of the rest of the coolant flow. At the same time, the key point of this method is the condition that the transient thermal conductivity of the LBL should be lower than the thermal conductivity of the turbulized part. If this condition is not fulfilled, it is concluded that the corresponding classical empirical equation is not suitable for calculating the heat transfer coefficient. A 45% aqueous solution of propylene glycol was taken as a model liquid, which can be widely used in solar collectors, in particular with nanofillers. This coolant is interesting because at a constant speed of V = 0.93 m/s, and the linear size (diameter) of the "live section" of the flow D = 0.021 m in the temperature range of 243–273 K it moves in the laminar mode, in the temperature range of 283–323 K — in transient mode and 333–353 K — in turbulent mode. A new formula is proposed for calculating the coefficient of turbulence of the coolant flow a, the numerical values of which are experimentally found in literary sources only for the air coolant.

We employed a highly concentrated model of wastewater to conduct our research, accurately mimicking the composition of wastewater generated by milk processing enterprises. Wastewater contained milk protein, carbohydrates, and whey sugars. Domestic wastewater, which served as a source of indicator fecal microorganisms, was added to them. The water purification and disinfection scheme involved treating a model wastewater using the biosorption method with an immobilized biocenosis in a laboratory installation, followed by further purification and disinfection in a decontamination tank. In comparison, we assessed the degree of microorganism elimination using distinct methods such as ozonation, hydrogen peroxide treatment, and combination of О3/Н2О2. It has been demonstrated that model wastewater, purified and disinfected using the AOPs method, also contains dissolved oxygen, which is non-toxic to aquatic microbiota.

Published: September 2024

The work by the authors, using a systematic approach, analyzes a group of software tools that are functionally oriented towards the automated implementation of configuration and management processes in IT infrastructures. The research profile focuses on a methodology known in the professional environment as “Infrastructure as Code” (IaC) and is one of the foundational methodologies implemented in a systemic combination within the DevOps methodology. This methodology is actively used in processes of dynamic formation, deployment, and maintenance of corporate IT infrastructures in many modern successful high-tech companies to achieve the best business performance, efficiency, guaranteed success, and security. The article discusses two basic approaches to building software tools that implement the IaC methodology, namely the declarative and imperative approaches. The main emphasis is placed on the formation of a set of advantages and disadvantages inherent in software tools such as Terraform, ARM, Ansible, and CloudFormation. The focus of researchers on these four software tools is explained by their leading positions in a fairly extensive lineup of possible alternative software products that allow for a comprehensive implementation of the IaC methodology in the context of full and functional systemic deployment of the DevOps methodology in specific implementations of corporate IT infrastructures. The authors' generalized conclusion of original scientific research is that there is currently no single clearly distinguished universal software tool among others that fully satisfies the entire spectrum of requirements and needs. Potential users in this context are communities of DevOps professionals and clients – owners and managers of modern dynamic high- tech and successful companies, firms, and businesses that rely on modern information systems and technologies.

Published: September 2024

Computer methods for process research and methods for processing the measurement results of the parameters of these processes are widely used in biology and medicine. Therefore, the problem of automation of biophysical measurements and computer processing of the results of such experiments is relevant.
In the treatment of wounds and burns with a large surface area of tissue damage, medicine has to resort to artificial skin. A procedure for studying thermal processes in artificial skin and measuring its thermophysical parameters was developed. The measurement process was described. The thermophysical parameters of the artificial skin samples used in medicine for the treatment of wounds and burns were determined.
The samples of the artificial skin used were made in Ukraine. Each sample was made from six layers of skin. To control the temperature distribution in the sample between the skin adjacent layers and on the surface of the sample, thermocouples were placed. The surface of the sample was heated with an incandescent lamp. The thermocouple signals were sent to an analog-to-digital converter (ADC), amplified, and digitally transmitted to a computer. Processing was carried out using the ADC software and the MATHCAD program. A mathematical model was obtained. For this purpose, a differential equation describing thermal processes in the sample was solved. The found temperature distribution function and its changes over time are in a good agreement with experimental data. The analysis of the function allows finding the thermal conductivity coefficient of artificial skin, its volume heat capacity, thermal diffusivity coefficient, and heat exchange coefficient with the external environment.
The proposed method of measuring and processing experimental data makes it possible to detect main thermophysical parameters of artificial skin. Based on these results, a theoretical model was obtained that well describes the course of thermal processes in artificial skin, which makes it possible to predict the course of these processes.
Such method is based on heating the skin with optical radiation. The thermal conductivity and thermal diffusivity of artificial skin are significantly less than such parameters of human skin, which should be considered when using it.

Published: September 2024

The decrease in the effectiveness of conventional marketing communications and the need to optimize marketing budgets require modern non-network players in the finishing materials market to take a more balanced approach to the formation of an integrated set of communication tools. Within the framework of this study, four types of marketing information transmission channels were identified. A tiered approach was used for typing, based on determining the type and number of communication intermediaries between a non-network seller and a buyer of finishing materials. A list of opportunities and threats of using a communication channel is defined for each type, which allows operationalizing the process of developing marketing communications. In order to optimize the procedure of developing a marketing communications package, lists of relevant marketing communications tools were formed, ranked by the degree of influence on sales volumes. To conduct the research, methods of included observation, survey and analysis of marketing internal reporting documents were used. The objects of observation - non-network sellers of finishing materials in the Siberian Federal District. The respondents - specialists who make decisions on the integration of marketing communications.
Analysis of the childfree phenomenon and the formation of traditional family values among modern students in the region (case study of the Omsk region)
Authors: Gokova Olga V.
Published: September 2024

Today, the demographic situation in Russia has become extremely challenging. According to official statistics, in 2022, there were 594,557 more deaths than births. Over the period from 1991 to 2022, natural growth in Russia was positive only for two years, in 2013 and 2014, and averaged 24,013 to 32,038 per year. The peak prevalence of death over birth occurred in periods when the economic, social, and political conditions were the most challenging. Between 1999 and 2005, and again in 2020 and 2021, Russia saw a decline in birth rates, with the number of deaths exceeding the number of births. This resulted in a loss of between 700,000 and 900,000 people during these periods. There are several factors contributing to this situation, but one of the major concerns today is the relatively low birth rate in the face of social, economic, and political upheaval. According to national opinion polls, people aged 25 to 29 years old want an average of two to three children, while the estimated number of children per person is 1.99 for women and 2.02 for men. The total fertility rate in 2022 is 1.42 children per woman. In other words, indicators characterizing people's potential readiness for childbearing actions are relatively low and become lower when considering their desires and opportunities. Against this backdrop, various social trends are emerging. While for most people, leading a family life with at least one child can be considered happiness, there are now individuals who choose to live a childless life. This phenomenon is known as childfreedom and is controversial, as it causes disagreement among many people. Today, childlessness is not only a health issue, but also a social and psychological one, as only a portion of the population associates childlessness with infertility. Therefore, in order to develop a strategy for educating the younger generation, it is essential to understand the family values and attitudes of modern young people towards the phenomenon of being childfree.

Published: September 2024

To achieve the strategic goals of digital transformation, it is necessary to consider the digital maturity of organizations, industries, and regions. The initial level and potential for digitalization of different industries, regions, and organizations vary significantly. Recent global macroeconomic and social shocks have driven the development of digital services, technologies, and platforms in healthcare. These changes have led to a transformation in the operating models of public and private medical organizations. However, there are negative consequences to these changes, including a decrease in the availability of certain technologies, equipment, and software, as well as an increase in the time and financial costs of digital transformation. The interregional differentiation in digital health maturity not only depends on spatial differences in socio-economic, innovative, technological, and digital development, but also on other factors that need to be taken into account.We believe that the use of various healthcare digitalization models in different regions affects the level of digital maturity in this sector. The aim of the study is to identify typical models of digitalization in regional healthcare systems. Various approaches were used in the research, including the index method, statistical and comparative analysis, content analysis, expert assessments (both in-depth interviews and free interviews), and others. The study utilized data from the Federal State Statistics Service, the Ministry of Digital Development of Russia, and the Unified Interdepartmental Information Statistics System. The focus of the study was on the Sverdlovsk and Tyumen regions. A comparative analysis of digitalization practices in these regions revealed two main models: "centralized" (the case of Tyumen) and "decentralized" (Sverdlovsk). We found that intermediate results for the "centralized" model are generally higher than for the "decentralized". A promising area of research is evaluating the final outcomes of the digital transformation of regional healthcare systems.

Sustainability indicators of regional industrial systems
Authors: Miller Alexander E. , Drozdov Danila O.
Published: September 2024

The article presents the results of a study on the development of a scientific approach to assessing the sustainability of industrial enterprises in a particular region. The study proposes a new approach to selecting indicators for measuring the sustainability of these enterprises. This approach helps to identify the goals and objectives of the enterprises, as well as the social, environmental, and economic aspects of their operations. One of the main features of this approach is its focus on systematizing the key indicators of sustainability. This allows for a more comprehensive understanding of the components that contribute to sustainable development, and for the identification of specific indicators that are relevant to each component. This information can then be used to develop effective strategies for achieving sustainable growth and development for these enterprises. The approach under study contributes to the development of the main elements of the non-classical theory of sustainable development. This allows us to consider sustainability indicators as both factors and conditions for the development of priority areas. From a practical perspective, the studied approach to evaluating indicators should be seen as a tool for achieving sustainable economic growth. It allows for maintaining internal balance and dynamic equilibrium within regional enterprises, while rationally utilizing the region's resource potential. The focus is on ensuring a sufficient level of development indicators, taking into account both external and internal environmental influences.The advantages of quantitative evaluation indicators include the ability to choose a dynamic development path by quantifying all its components; minimizing factors associated with risk of loss; a high probability of sustainable development influencing enterprise profitability; an analytical base for operational monitoring of changes in sustainability indicators under uncertain conditions.

Authors: Stuken Tatiana Yu. , Lapina Tatiana A. , Korzhova Olga S. , Korzhov Evgenii V.
Published: September 2024

The article examines the impact of digital technologies on labor productivity growth on the example of Russian regions. The connection between digitalization and labor productivity is not obvious due to the presence of time lags, imperfect information, peculiarities of the distribution of surplus between market players, the presence of complementary assets that can change at different speeds, etc. Therefore, the question of the impact of digitalization on the level of labor productivity in Russia remains open. The information base of the study is the official data of regional statistics and Monitoring of the development of the information society in the Russian Federation for the period from 2016 to 2020. Based on available data, the article uses several approaches to assess computer capital and several modifications of the Cobb-Douglas model to assess the relationship between digital capital and labor productivity. Comparing the results obtained in models of different specifications, we can note a statistically significant positive impact of the spread of the Internet on labor productivity growth. In general, this result is consistent with the conclusions of studies performed on other data and in other countries. This means that the implementation of an active policy to reduce the digital divide and "digital cohesion" between regions by identifying and removing barriers can and should contribute to the overall growth of labor productivity.

Forecast of economic growth and development of the region: searching for sources to increase reliability
Authors: Batievskaya Veronika B. , Sokolovsky Mikhail V.
Published: September 2024

The article discusses forecasting regional development in the Kemerovo Region - Kuzbass. It focuses on selecting and analyzing the dynamics of key regional macroeconomic indicators. The authors define the difference between "economic growth" and "economic development" by identifying a set of quantitative indicators that characterize each concept. Economic growth is achieved through the additional use of labor, space, and equipment in production, as well as increased mining, development of new land, and construction of new facilities. Economic development, on the other hand, is measured by qualitative indicators such as labor productivity, human development, and others. Using the extrapolation method and changes in certain indicators, the authors predict the growth of the gross regional product (GRP), changes in the proportion of high-tech and knowledge-intensive products in GRP, and the labor productivity index. The quality of the forecast model was evaluated using the approximation reliability coefficient, which indicated a low degree of consistency between the trend model and the original data. Based on this, it was concluded that the forecast quality needs to be improved by incorporating additional analytical information. This includes materials from the Ministry of Economic Development of the Russian Federation, the Analytical Center under the Government of Russia, macroeconomic research institutions of major financial and credit organizations, and data from foreign and domestic analytical agencies. The study is based on systematic and structural analysis and statistical data processing using extrapolation methods. The work utilizes official documents, data from the Federal State Statistics Service (FSSS) and its regional (Kemerovo) branch, government agencies of the Russian Federation, and scientific publications available in the public domain.

Genetic algorithms for the location of ground stations for a global satellite communications network
Authors: Levanova T.V. , Gette A.V.
Published: September 2024

Global satellite networks provide communication in various parts of the Earth. To ensure communication in large areas, it is necessary to locate ground stations that interact with satellite systems. The solution to the problem of location and design of ground stations can be divided into two stages. At the first stage, a set of ground stations under construction and the configuration of their equipment are determined. At the second stage, data packet routes are regularly calculated in each time interval, taking into account requests from customers and the current state of the communication network. The quality of customer service in a time interval is measured as the average number of lost or unrouted packets per unit of time. Previously, when solving the routing problem, it was assumed that all stations and transmitting deviceshad already been selected. In this paper, the problem is considered as a two-stage one, in which it is necessary to solve the issues of the first and second stages together. The criterion is to minimize the total number of lost packets. To do this, a genetic algorithm and a genetic local search algorithm were built, their experimental study was performed, and a comparison with other algorithms was carried out.

Published: September 2024

Objectives: This study aimed to explore the effects of a cognitive behavioral therapy (CBT) program on stroke patients, as well as their experiences participating in the program.Methods: This study employed a mixed-methods design, integrating qualitative case studies with quantitative analysis. We included 20 stroke patients, randomly divided into 2 groups of 10 each: an experimental group and a control group. The experimental group underwent a CBT program comprising 20 sessions, in addition to receiving general occupational therapy. Conversely, the control group participated in meditation relaxation sessions alongside their general occupational therapy. Both interventions were administered daily for 60 minutes, 5 days a week, over a 4-week period.Results: After the intervention, the experimental group exhibited significant improvements in depression, anxiety, self-efficacy, and rehabilitation motivation (p<0.01, p<0.05). In contrast, the control group only demonstrated a significant reduction in anxiety (p<0.05). A comparison of the changes between the 2 groups showed significant differences in depression and anxiety (p<0.01), but no significant differences in self-efficacy and rehabilitation motivation (p>0.05). In-depth interviews with 10 participants from the experimental group were conducted and analyzed, revealing 4 core themes: “psychological stability,” “physical symptom relief,” “altered daily routines,” and “challenges and hopes for change.”Conclusion: The findings of this study suggest that CBT programs may serve as a valuable intervention, offering psychological support and rehabilitation for stroke patients.

This research aims to determine teachers' strategies in implementing guidance and counseling to instill morals in students. This research uses a qualitative method in which data collection is carried out through observation, in-depth interviews, and analysis of written documentation. Meanwhile, the data was analyzed using a thematic approach to find themes in the data collected in the field. The research results show that the teacher's strategy in implementing counseling guidance to instill student morals has been carried out well through several methods that the school has determined. Teacher strategies in implementing counseling guidance include oral form. The second strategy is counseling guidance in the form of practice. The results of this research also show that the supporting factors in cultivating students' morals at the Alkahiraat Senior Islamic High School are the family environment and infrastructure, and the inhibiting factors are the lack of support and attention from parents and the influence of peer environment. Suggestions for students at the Alkhairaat Alkahiraat Islamic Junior High School Palu are that they always be aware of their responsibilities as servants, obey the commands of Allah SWT, and stay away from his prohibitions. This will create students with noble morals, as we all hope for, according to the teachings of the Al-Qur'an and Hadith.

El desarrollo del Parque Urbano y el Centro Cultural para Jóvenes en Cuautitlán Izcalli es un proyecto integral que permite crear un espacio de pertenencia y desarrollo para la juventud local. A lo largo de este proceso, nos hemos enfocado en diseñar espacios que no solo respondan a las necesidades y expectativas de los jóvenes, sino que también fomenten un sentido de comunidad y pertenencia. La exhaustiva investigación realizada para entender y satisfacer las diversas necesidades de los usuarios ha sido clave para el diseño del proyecto, asegurando que cada área se adapte a las diferentes edades y actividades para las que está destinada. La implementación de materiales innovadores, como la madera, ha sido un desafío enriquecedor que nos ha impulsado a explorar nuevas técnicas y enfoques en el diseño arquitectónico. Esta elección de material no solo ha presentado una oportunidad para superar nuestras limitaciones previas, sino que también ha ampliado nuestro conocimiento sobre la aplicación de materiales en la arquitectura. A través de este proceso, hemos aprendido a balancear la estética y la funcionalidad, integrando la madera de manera efectiva en la estructura del edificio. Cada componente del proyecto, desde la casa hogar hasta el gimnasio, la cafetería y la tienda, ha presentado retos específicos que se han abordado con creatividad y determinación. La integración de estas diferentes funciones en un solo conjunto cultural ha requerido una cuidadosa planificación para garantizar que todos los espacios trabajen en conjunto de manera eficiente. Se ha priorizado la estética, funcionalidad, accesibilidad y confort, buscando crear un entorno que no solo sea visualmente atractivo, sino que también ofrezca una experiencia de usuario excepcional.
The theory of planned behavior explored in entrepreneurial intentions among university students in Shandong province, China
Authors: Dong Shixue , Chang Yuancheng
Published: September 2024

This study, based on the Theory of Planned Behavior (TPB), aims to explore the entrepreneurial intentions of university students in Shandong Province, China, and analyze the major factors influencing these intentions. Structural Equation Modeling was applied to data collected from 680 students across five universities in Shandong Province. The findings reveal that attitudes, subjective norms, and perceived behavioral control significantly influence the students’ entrepreneurial intentions. Specifically, a positive attitude towards the outcomes of entrepreneurship emerged as the strongest factor influencing their intentions, indicating that positive perceptions and expectations of entrepreneurship significantly enhance students’ entrepreneurial inclinations. Perceived behavioral control also showed a strong influence, suggesting that enhancing students’ self-efficacy and awareness of accessible resources is crucial for fostering entrepreneurial intentions. However, the influence of subjective norms was weaker, which may relate to specific cultural and social environmental factors. This study not only provides an empirical basis for entrepreneurship education and policy-making in Shandong Province and beyond but also offers new insights into the application of TPB in the field of entrepreneurship research.
Ajdukiewicz’s Semantic Turn
Authors: Brożek Anna
Published: September 2024

Ajdukiewicz called his article Problemat idealizmu transcendentalnego w sformułowaniu semantycznym [The Semantic Version of Transcendental Idealism], published in “Przegląd Filozoficzny” in 1937, a “turning point” of his philosophical development. The aim of the paper is to present various aspects of this turn. Firstly, the historical and philosophical background of the 1937 paper is sketched. It includes the metaphilosophical position of the Lvov‑Warsaw School, and the development of methods applied in this group. Secondly, Ajdukiewicz’s ideas up to 1937 are outlined in order to present what the semantic turn consisted in. Next, the program of the semantic theory of knowledge is sketched, and the steps of Ajdukiewicz’s argumentation against transcendental idealism, with an emphasis on the use of metalogical and semantic results, are presented. Finally, Ajdukiewicz’s proposal is discussed from the methodological point of view.
Filozofia nauki w twórczości Izydory Dąmbskiej
Authors: Orbik Zbigniew
Published: September 2024

In the paper, I present the achievements of the outstanding female representative of the Lvov‑Warsaw School Izydora Dąmbska in the field of philosophy of science. The following issues are analysed: the concept of the philosophy of science, the question of irrationalism in scientific cognition, the problem of scientific laws, and the meaning and role of analogy in science. Following the development of the issues classified as the philosophy of science in Dąmbska’s works, it is easy to notice that she takes a realistic view as far as the concept of knowledge is concerned. However, she also has a tendency to emphasize the importance of subjective factors and the role of so‑called operators in scientific cognition.
Supozycyjna koncepcja wiary religijnej Władysława Witwickiego
Authors: Rechlewicz Wojciech
Published: September 2024

Władysław Witwicki’s suppositional conception of religious faith was presented extensively in his book La foi des éclairés [Faith of the Enlightened] (1939). The aim of this work was to investigate how so‑called enlightened people (i.e. those with at least a secondary education) reconcile secular knowledge with religious faith. The empirical research presented by Witwicki was based on a number of concepts, such as judgment, supposition, psychological principle of contradiction, sincere belief and insincere belief. Witwicki concluded that the faith of enlightened people consists of suppositions which are held against secular beliefs. However, this conclusion was not sufficiently justified and can only be applied to a certain group of believers.
