This paper addresses the issues related to designing and estimating the strength of solid-alloy elements in the deforming broaches of significant diameter (exceeding 150 mm) for the developed process of discrete broaching. The tool limit condition was assessed based on two strength criteria: the specific potential energy of shape change and the maximum tangent stresses. Numerical modeling using the finite element method has made it possible to derive the distribution of equivalent stresses in the tool elements and the contact stresses (...) at the surface of the contact between a solid-alloy insert and the body, which enabled the analysis of tool strength under loading. The simulation was performed under a single normal load, which ensured the versatility of the calculation for any contact pressure values. We have derived formulae to calculate the acceptable contact pressure depending on unit load. The effect of the insert protrusion height over the body on the strength of tool elements has been established. We have derived engineering dependences that determine the required magnitude of insert protrusion over the body depending on the ultimate load. An example of calculating the strength of a prefabricated deforming element in the machining of a sleeve made from gray modified cast iron of hardness HB230 has been considered. Our calculations have shown that the deforming element designed for the new technological process corresponds to the conditions of strength, provided the ratio h1/h=0.15 is maintained (where h1 is the insert height above the body, h is the insert height). The results obtained could be used in engineering calculations when designing the prefabricated tool for discrete deformation, as well as to assess the strength of prefabricated tools, such as cutters, core drills, reamers, when refining external loads.

Purpose. To determine the potential of deforming broaching for the improvement of efficiency of cutter chisels in the mining industry. Methodology. The study of the application of the technological process of deforming broaching was carried out based on the experimental research into conditions of assembly of press couplings corresponding to cutting rock-destroying tools, the working surface of which is reinforced with solid-alloy inserts. Findings. Based on the conducted research, a new process of assembling the crowns of cutter chisels with the (...) use of deforming broaching was developed. Originality. It was determined that the range of angles of inclination of generatrix of the working cone of the deforming element and the roll-treading lip of the insert, which are necessary for efficient machining and pressing in crowns of cutters, is 4–16°. It was proven that the “solid alloy-steel” press couplings for cutter chisels will have the maximum bearing capacity at total tension a/d0 ≤ 3 %. It was found that it is necessary to foresee the following distribution of tensions: to perform 2 % of deformation by preliminary deforming broaching, and 1 % ‒ by pressing in an insert Practical value. The use of deforming broaching makes it possible to increase the strength of fastening the inserts of cutter chisels by 2 times, to reduce specific consumption of the tool by 4.4 times, and to increase the average drilling rate by 4 times.

The article gives a definition of the technical and economic potential of the application of the deforming broaching process. Research of the consequences of introducing deforming broaching into technological processes at manufacturing enterprises is carried out on the basis of application of system resource and matrix approach. On the basis of the performed researches, a methodological basis for the economic evaluation of the results of applying deforming broaching on the pro-duction has been developed. The article has improved the well-known scientific (...) and methodological foundations for the determination of technical and economic results of the application of deforming broaching due to the complex identifica-tion of production-organizational decisions - in technical and forms of evaluation in economic spheres. The developed approach gives an opportunity to more accu-rately assess the economic effect of introducing deforming broaching on the min-ing, metallurgical and machine building industries. It can be used to assess the economic effect of introducing other process parts processing. (shrink)

Volunteering in Ukraine is becoming an increasingly popular phenomenon that occupies an important place in the life of society. Many people choose volunteering as a way to help people in difficult life circumstances, as well as to develop their own personality and engage in active civic participation. As a significant social phenomenon, volunteering has its own ideological foundations that define its core values and principles. Volunteering is based on the desire to help people and nature regardless of their status, nationality, (...) religion, or political beliefs. The purpose of the study. The current study examines the ideological foundations of volunteering in Ukraine in wartime and their significance for volunteering, to study the practical experience of volunteers in Ukraine in 2014-2023, and to examine the peculiarities of the legal regulation of volunteering in Ukraine in wartime. Methods. Achieving the goal and objectives of the study was made possible by using a set of interrelated modern general scientific and special methods and approaches. The systematic approach made it possible to study volunteering as a holistic set of elements in the totality of the connections between them. Through the use of the method of systematization, the author provides a review of the legal framework for volunteering, factor analysis is used to determine the factors influencing the relationship between the state and society in the field of volunteering, and system analysis is used to assess the state of relations between the state and society in Ukraine at this stage through its quantitative indicators.Results. According to the study “Volunteer Movement in Ukraine”, prepared by GfK Ukraine on behalf of the UN in Ukraine, Ukrainian citizens pay great attention to the volunteer movement in the development of social processes: 62% recognize the role of volunteers in the changes in the last year; 85% believe that the volunteer movement helps strengthen peace; 81% tend to consider the volunteer movement an essential component of civil society. Regarding the legal regulation of volunteer activities in Ukraine, the Law of Ukraine “On Volunteer Activity” of April 19, 2011, No. 3236-VI was adopted in April 2011. The Law of Ukraine of 15.08.2022 No. 2519-IX On Amendments to the Law of Ukraine “On Volunteer Activity” on Support of Volunteer Activity regulates social relations related to volunteer activity in Ukraine. Discussion. One of the key principles of volunteering in Ukraine is selflessness and the ability to work in extreme conditions. Volunteers often work in difficult and dangerous conditions that require a high level of professionalism and skills. For many volunteers, the Ukrainian revolution of 2013-2014 and the events in eastern Ukraine were turning points that forced them to change their attitude to their own lives and start helping others. Ukrainian volunteers are an example of community and state cooperation that contributes to ensuring security and helping victims. They have shown that volunteering can be an effective tool in the fight against war and its consequences. Many volunteer organizations provided free medical care, took on the responsibility of supplying the military with necessary items and military equipment, organized the evacuation of people from the war zone, and provided psychological support to the military and their families. Conclusions.Volunteering in Ukraine is not a new phenomenon, but the war with Russia has become a catalyst for its development. This is a great example of how crises can encourage people to act together and interact to achieve a common goal. Volunteerism in Ukraine demonstrates the importance of spiritual unity and cooperation in difficult times, and is one of the most striking examples of civil society in action. The ideological principles of volunteering in Ukraine include non-profitability, openness, spirituality, and humanism, transparency and openness, security, and cooperation with government agencies and the military. The volunteer movement in Ukraine, especially in times of war, is an important factor in ensuring security and helping victims. Involvement of different groups of the population in volunteer activities, as well as cooperation with state and international structures, are important to ensure the effectiveness and success of volunteer activities.

With the rapid development of society and the dramatic change of environment, previous career counseling focusing on personal choice has been difficult to meet individuals’ needs. It is very meaningful and valuable to introduce the ideology of Life Design Counseling. In this mini review, we introduce and analyze the theory and methodology of LDC. This review puts forward challenges in the field of LDC, including the lack of attention to clients from multiple backgrounds and professional counselors, the lack of diversified (...) methods in the intervention process, and the lack of diversified research. The theoretical research, practical research, and the integration of theory and practice of LDC still need to be further concerned by researchers. (shrink)

The aging of the two brothers in the “twins paradox” is analyzed through the space-time evolution of the densities that correspond to their internal complex structure. Taking into account their relative motion, it is shown that the traveling brother evolves over a shorter interval of time than his twin, which makes him younger than his brother.

Autumn 1918 p. the breakup of the war-weakened Austro-Hungarian Empire was evident. Taking into account the existing claims of the Poles on the territory of Galicia, the first task of the Ukrainian parliamentary representation was to prepare for the re-election of the authorities in the region. On his initiative October 18-19, 1918 p. a constituent was held in Lviv - "a representative assembly of Ukrainian ambassadors to the parliament and regional councils of Galicia and Bukovina, bishops, delegates of Ukrainian parties...".

Andrey Sheptytsky - Metropolitan of the Greek Catholic Church, belongs to the key figures of Ukrainian history of the first half of the twentieth century. Its influence on the spiritual and national-political life of Ukrainians of that time, the processes of crystallization of national consciousness, as well as on the sphere of practical politics, cannot be overestimated. A. Sheptytsky's life path is an object of constant attention of historians, but it would still be early to assert its full and comprehensive (...) coverage. One of the debating issues in historiography remains the formation of national-political and religious views of the future Metropolitan. As you know, A. Sheptytsky was descended from the Polonized family, the process of his upbringing and education took place in the circle of Polish culture and national-state tradition. Already at adulthood, he made a conscious choice in favor of the Ukrainian Church and nation. The reasons and motives for this choice require a thorough study, taking into account the many factors that led it. (shrink)

A special place in A. Sheptytsky's socio-political activity is occupied by parliamentary activity. Considering the fact that the Metropolitan has been intolerant of the use of terror in political struggle, it becomes clear why parliamentary methods of struggle were most effective for him.

Communitarianism has been misunderstood. According to some of its proponents, it supports the ‘Asian values’ argument that rights are incompatible with communitarian Asia because it prioritises the collective interest over individual rights and interests. Similarly, its critics are sceptical of its normative appeal because they believe that communitarianism upholds the community’s wants and values at all costs. I dispel this misconception by providing an account of communitarianism, properly understood. It is premised on the idea that we are partially constituted by (...) our communal attachments, or constitutive communities, which are a source of value to our lives. Given the partially constituted self, communitarianism advances the thin common good of inclusion. In this light, communitarianism, properly understood, is wholly compatible with rights, and is a potent source of solutions to controversial issues that plague liberal societies, such as the right of a religious minority to wear its religious garment in public.

In this paper, an active frequency control strategy of wind turbines based on model predictive control is proposed by using the power margin of wind turbines operating in load shedding mode. The frequency response model of the microgrid system with the load shedding of the wind turbines is used to predict the output power and system frequency deviation of the wind turbine. According to the prediction information, the output power control signal of the model predictive controller in the wind turbine (...) can be optimized. On this basis, a wind turbine active participation frequency control strategy based on model predictive control is designed by rolling prediction and optimization. The wind turbine power control signal after the strategy is used to adjust the output power of the wind turbine and balance the change of the active power of the system to reduce the frequency deviation.

We investigate the group of definable homomorphisms between two definable abelian groups A and B, in an o-minimal structure . We prove the existence of a “large”, definable subgroup of . If contains an infinite definable set of homomorphisms then some definable subgroup of B admits a definable multiplication, making it into a field. As we show, all of this can be carried out not only in the underlying structure but also in any structure definable in.

Attending cram school has long been a trend in ethnic Chinese culture areas, including Taiwan. Despite the fact that school reform policies have been implemented in Taiwan, cram schools have continued to prosper. Therefore, in this educational culture, how to achieve a good educational effect is also a topic worthy of discussion. However, whether students really engage in those tutoring programs provided by cram schools has seldom been studied. To address this gap, this study explored how parents’ hovering attitude toward (...) life and coursework influences their children’s engagement in cram schools. This study targeted those students who attend English cram schools to test the correlates between two types of helicopter parenting, tutoring engagement and continued attendance at cram schools. A total of 320 questionnaires were sent out, and 300 were returned, giving an overall response rate of 93.75%. Excluding seven incomplete or invalid questionnaires, 293 valid questionnaires were received. The results of this study show that hovering behavior awareness is negatively related to cram school engagement, whereas cram school engagement is positively related to the intention to continue attending cram school. Moreover, the results imply that parents should alleviate their helicoptering behavior to enhance their children’s engagement in cram school tutoring programs. (shrink)

The author elucidates the ontological basis of elementary mathematical theories and thereby assesses their certainty as a foundation for the more complex theories of modern mathematics, such as mathematical analysis and set theory. He adduces arguments in favor of the position of Frege, who held that geometry can provide a sufficiently broad and certain foundation for mathematics.

An o-minimal expansion of an ordered group is called semi-bounded if there is no definable bijection between a bounded and an unbounded interval in it (equivalently, it is an expansion of the group by bounded predicates and group automorphisms). It is shown that every such structure has an elementary extension.

With advances in technology and the popularity of the Internet, consumers increasingly rely on various sources of electronic word-of-mouth, such as online user reviews and critical reviews, in their decision-making processes. Despite general consensus on the importance of eWOM and the ability of critical reviews to influence product sales, very little is known about the mediation between critical reviews and user reviews. Therefore, we used path analysis to examine how critical reviews and user reviews simultaneously affect box office revenues using (...) eWOM data collected from Metacritic.com and IMDb.com, and box office revenue information collected from BoxOfficeMojo.com. The results showed that critical reviews valence not only directly affects box office revenues but also increases active postings in the community and user reviews volume, thus indirectly leading to greater box office revenues. The study provides strategic guidance and practical implications for eWOM communication management. (shrink)

This study applies identity and social identity theories to develop and test a framework in which retail brand personality influences consumer outcomes [i.e., positive word-of-mouth about and patronage intention toward the retailer] through public and/or private self-congruity, strengthened by shopping conspicuousness situation, and retail brand identification. This is the first study to include social shopping situations to study brand personality and self-congruity. A questionnaire with a 2 × 2 between-subjects design was conducted on a sample of US consumers. Structural equation (...) modeling was used to test the hypotheses. The findings suggest a framework in which Genuine, the most influential dimension of retail brand personality, predicted outcome behaviors both directly and indirectly through self-congruities and RBI. The high shopping conspicuousness situation strengthened the relationship between public self-congruity and the overall RBI. The concept of RBI provides an additional theoretical perspective for guiding future research on shopper–brand relationships. In addition, this framework provides practical implications for retail environment design and customer-brand relationship management. (shrink)

A toy is a valuable medium for promoting parent-child interaction. This study selected six light-emitting or reflective materials to produce composite toy balls, and conducted tests on 15 families with preschool-aged high-functioning autistic children. Quantification method I analysis was employed in the study, and the experimental results indicated that (a) the metal ball (reflective and dynamic light) was the representative sample that elicited many smiles or laughs and much finger pointing as well as high levels of pleasure and activeness.; (b) (...) the mitball (static light) was the representative sample that provoked much eye contact, produced satisfactory reactions to activities,; (c) the quality of fluorescence enhanced the levels of pleasure and the reactions to the activity. We propose that dynamic and reflective materials can be adopted to divert the attention of children, and fluorescent toys can then employed to sustain parent-child interaction. (shrink)

We consider reducts of the structure $\mathscr{R} = \langle\mathbb{R}, +, \cdot, <\rangle$ and other real closed fields. We compete the proof that there exists a unique reduct between $\langle\mathbb{R}, +, <, \lambda_a\rangle_{a\in\mathbb{R}}$ and R, and we demonstrate how to recover the definition of multiplication in more general contexts than the semialgebraic one. We then conclude a similar result for reducts between $\langle\mathbb{R}, \cdot, <\rangle$ and R and for general real closed fields.
