Authors: Malini Ramu , Malini Ibrahim
Published: February 2022

Agriculture development is an index of country’s progress because the development of all other sectors depends upon the development of agriculture sector. But, the development of agriculture is affected by natural disasters. Agriculture insurance is an only protective mechanism against the perils present in agriculture. It largely solves the problem of farmers and largely in the hands of farmers. The subscription and success of agriculture insurance is determined by its cost and benefit. If the farmers have positive opinion on cost and benefit of agriculture insurance they will come forward to subscribe and stabilize their wealth and sustain the economic growth of nation by agriculture. This phenomenon, induce the researchers to stumble upon the solution to assess the opinion of farmers on cost and benefit of agriculture insurance and to test the significant difference in the farmers’ opinion on cost and benefit of agriculture insurance.
The primary data collected from 600 farmers availing agriculture insurance within Tirunelveli District in the Indian State of Tamil Nadu to make an in-depth study to address the above issues. The respondents were selected by adopting stratified random sampling technique. The collected data were analyzed by applying Percentage Analysis and Sign test. The study revealed that green insurance is a beneficial plan to the farmers to face the negative income shock at reasonable premium. The majority of the respondents felt that agriculture insurance has covered 0-50% risk. Sign Test proved that there is a significant difference in the opinion of farmers on the cost and benefits of agriculture insurance. Technological adoption in the estimation of loss of crop yield, prompt settlement of claims and additional perils at additional premium are suggested mission to enhance the vision of the farmers on cost and benefits of agriculture insurance. Besides, it helps the farmers to lead a peaceful life and induce them to contribute more towards sustainable agriculture development of the country.

A magyar zeneszerzői hagyomány folytatója a 21. században: Tallér Zsófia (1970-2021)
Authors: Dallos Márta
Published: February 2022

A tanulmány célja egyrészt, hogy a fiatalon elhunyt, tehetséges, sokoldalú zeneszerző, Tallér Zsófia munkásságára irányítsa a figyelmet, másrészt, hogy a kortárs zene és az iskolai ének-zene oktatás összekapcsolásának néhány szempontja révén inspirációt adjon a zenepedagógusok számára. Tallér Zsófia tanáraitól, Draskóczy Lászlótól, Bozay Attilától és Petrovics Emiltől a magyar zeneszerzői hagyomány elveit és eszközeit sajátíthatta el, műveinek fontos eleme a témafejlesztés és a melodikus gondolkodásmód. A kísérletező technikák helyett a hagyományos dallamalkotással dolgozott, mindig szem előtt tartotta, hogy hús-vér embereknek komponál. Petrovics Emil hatására fordult a színpadi zene felé, munkáiban a drámaiság, az érzelmek és a zene kapcsolata érdekelte. Szívesen komponált gyermekeknek, kedvelte a klasszikus meseirodalmat. A tanulmány három különböző műfajú, gyermekeknek szánt zeneművét mutatja be, amelyek élményszerűen használhatók az ének-zene órákon. A Boribon muzsikál című dalsorozat (2010), a Kippkopp és Tipptopp című zongorasorozat (2009) és a Leander és Lenszirom című kétfelvonásos opera (2015) – amelyet 3 évadon át tartottak a Magyar Állami Operaház műsorán – változatos pedagógiai lehetőségeket nyújtanak a zenei képességfejlesztés, a hangszertanulás és a befogadóvá nevelés területén.
A magyar gyermek- és népdalfeldolgozások Bartók Béla: Gyermekeknek sorozatában
Authors: Szesztay Zsuzsa
Published: February 2022

A tanulmány a 20. század egyik legjelentősebb magyar zeneszerzője, népzenetudósa és zongoraművésze, Bartók Béla (1881–1945) születésének 140. évfordulója előtt tiszteleg. A magyar gyermek- és népdalfeldolgozások különleges inspirációs forrást jelentettek Bartók 1908 és 1911 között keletkezett korai zongoraműveiben. Egyik legjelentősebb műve az 1908–1909-ben készült négy füzetből álló Gyermekeknek című sorozat. A zongoraciklus, melyet a zongorista- és zenepedagógusi tevékenységet is folytató Bartók kifejezetten a zongoratanulás kezdeti éveire szánt, máig a zongoraoktatás egyik legértékesebb alapműve. A Gyermekeknek első és második kötetének öt gyermekdal feldolgozása Forrai Katalin Ének az óvodában című könyvében is fellelhető. Ezek a könnyen énekelhető, játékkal összekapcsolható énekek az óvodai énekes repertoár fontos részét képezik. Bartók a népzenét természeti jelenségnek tekintette és a nagy művészetek alkotásaival egyenrangú, tökéletes művészetként értékelte. A kisgyermekkori zenei nevelésben ezek az eszmék a magyar zenei nyelv elsajátításán és élményszerű befogadásán keresztül valósulhatnak meg.

Nationalism in Secondary Schools: How Do Students Understand and Conceptualize It?
Authors: Çiftçi Barış , Yücel Ahmet Galip , Durmaz Ahmet
Published: February 2022

One of the aims of educational institutions in Turkey is to adopt an understanding of nationalism based on Atatürk's views by students. Atatürk's understanding of nationalism was founded on the unity of culture. It rejects racism. It emphasizes cultural unity rather than blood ties or religious unity. However, various forms of nationalism in Turkey can find supporters. For this reason, it is important to examine how secondary school students understand nationalism and with which concepts they explain it. Qualitative research method was used in this research, which aims to examine how students conceptualize and understand nationalism. Since it is important for the students to express themselves naturally, they were asked to write an essay on nationalism. Student writings were analyzed by content analysis. According to the results obtained within the scope of the study, the students mostly used the expressions "to love homeland and nation" and "to protect homeland and nation" when explaining the concept of nationalism. As the age and grade levels of the students increase, the number of concepts related to nationalism used by students increases. Nationalism is understood differently by male and female students. While female students emphasize the concepts of love and work, male students emphasize the concepts of protecting and independence. Considering the place where the students live, the meaning attributed to the concept of nationalism varies. While the students living in the city center used the concept of love more, the students living in the town focused on the concept of protecting. The most important finding obtained within the scope of the study is that the participants did not base their nationalism on blood ties or religious unity. Students did not use non-inclusive expressions while describing nationalism. For this reason, it was understood that the participants had thoughts compatible with Atatürk's understanding of nationalism.

Published: February 2022

The existence of vernacular architecture has given characteristics to the built environment and area. Vernacular architecture has became into a distinct personality that differentiates one location from another. Bangli architecture is one of the various kinds of architecture that evolved in Bali. Bangli architectural style has evolved from the 15th century to the 18th century AD. The characteristics of Bangli's distinctive architectural design can be seen in the main entrance building called kori agung. Today the architectural style in Bangli began to be replaced by the entry of other architectural styles in the surrounding area. For this reason, documentation efforts are needed to explore the identity and characteristics of Bangli architectural design. This article describes the identification of Bangli's architectural style characteristics through the kori agung as an object of the investigation. Data collection was carried out through field measurements, interviews and historical literacy. Architectural inspection techniques and graphical analysis are used in the analytical method, with architectural drawings and forms serving as the primary instruments. As a result, drawings, sketches and visual analyses are used to describe the architectural qualities of kori agung, which are typical of Bangli.

To what extent do individual differences in infants’ early preference for faces versus non-facial objects reflect genetic and environmental factors? In a sample of 536 5-month-old same-sex twins, we assessed attention to faces using eye-tracking in two ways: initial orienting to faces at the start of the trial (thought to reflect subcortical processing) and sustained face preference throughout the trial (thought to reflect emerging attention control). Twin model fitting suggested an influence of genetic and unique environmental effects, but there was no evidence for an effect of shared environment. The heritability of face orienting and preference were .19 (95% CI: [.04, .33]) and .46 (95% CI: [.33, .57]), respectively. Face preference was associated positively with later parent-reported verbal competence (B = 0.14, 95% CI: [0.03, 0.25], p = .014, R2 = .018, N = 420). This study suggests that individual differences in young infants’ selection of perceptual input – social versus non-social – are heritable, providing a developmental perspective on gene-environment interplay occurring at the level of eye movements.

Published: February 2022

Purpose: We developed a mental health promotion campaign program to promote psychiatrichelp-seeking behavior among university students by adopting a social marketing approach and nudge theory from behavioral economics. The purpose of this study was to examine the effectiveness of the campaign. The campaign focused on the illustration of cognitive function- related symptoms and was called the “Fatigue of Brain” campaign.Methods: This study retrospectively compared the duration until psychiatric consultation at health care centers in a Japanese university between data obtained from our previous study (2016- 2018) with data from our newly developed mental health campaign (2018-2020). The campaign program included a small leaflet, given to all students during their physical examinations, which directed them to a special website.Results: The results of logistic regression analysis using data that met the eligibility and inclusion/exclusion criteria showed that the proportion of students (40.3%) who visited psychiatric consultations within two weeks of the campaign’s onset was significantly higher than the proportion of students visiting before the campaign (37.6%; OR = .578, 95% CI = .343 - .972, p = .039). Multivariate analysis revealed that the proportion of students with depressive symptoms (31.6%) was significantly higher during the campaign than before the campaign (17.3%; OR = .444, 95%CI = .234–.843, p = .013).Conclusions: The results suggest that our cognitive function-focused mental health campaign promotes earlier psychiatric consultation.
Using diverging predictions from classical and quantum models to dissociate between categorization systems
Authors: Epping Gunnar Paul , Busemeyer Jerome R
Published: February 2022

Quantum probability theory has successfully provided accurate descriptions of behavior in the areas of judgment and decision making, and here we apply the same principles to two category learning tasks, one task using information-integration categories the other using rule-based categories. Since information-integration categories lack verbalizable descriptions, unlike rule-based ones, we assert information-integration categorization decision results from an intuitive probabilistic reasoning system characterized by quantum probability theory, whereas a rule-based categorization decision results from a logical, rational probabilistic reasoning system characterized classical probability theory. In our experiment, participants learn to categorize simple, visual stimuli as members of either category S or category K during an acquisition phase, and then rate the likelihood on a scale of 0 to 5 that a stimulus belongs to one category and subsequently perform the same likelihood rating for the other category during a transfer phase. Following the principle of complementarity in quantum theory, we expect the category likelihood ratings to exhibit order effects in the information-integration task, but not in the rule-based task. In the information-integration task, we found definitive order effects in the likelihood ratings. But, in the rule-based task, we found that the order effects in the likelihood ratings are not significant.
The ‘perfect’ partner: Understanding the lived experiences of sex doll owners
Authors: Lievesley Rebecca , Reynolds Rebecca , Harper Craig A.
Published: February 2022

The ownership of sex dolls has become an increasingly discussed phenomenon in recent years, with legal scholars and legislators calling for increased regulation and criminalization of such articles. In doing so, they promote an implicit assumption that the ownership of dolls increases a risk of sexual offending, which has been questioned in recent survey-based psychological analyses. However, the literature is currently lacking a phenomenological exploration of the experiences of individuals who own sex dolls. In this study, we interviewed nine owners of sex dolls to investigate their motivations and experiences. Two main themes were elicited from the data: “the ‘perfect’ partner” and “sex doll or love doll?”. In understanding doll ownership in this way, we hope to add to ongoing social discussions about the types of people who own dolls, why they do so, and how dolls act as a function aspect of the sexual (and nonsexual) lives.
Discounting for money, food, and sex, over the menstrual cycle
Authors: Vincent Benjamin Thomas , Sztwiertnia Mariola , Koomen Rebecca , Warren Jasmine
Published: February 2022

Sexual desire, physical activity, economic, and other behaviours fluctuate over the menstrual cycle. However, we have an incomplete understanding of how preferences for smaller sooner or larger later rewards (known as delay discounting) change over the menstrual cycle. In this pre-registered, cross-sectional study, Bayesian linear and quadratic binomial regression analyses provide compelling evidence that delay discounting does change over the menstrual cycle. Data from 203 naturally cycling women show increased discounting (preference to more immediate rewards) mid-cycle, which is at least partially driven by changes in fertility. This study provides evidence for a robust and broad-spectrum increase in delay discounting (Cohen’s h ranging from 0.1-0.4) around the fertile point in the menstrual cycle across multiple commodities (money, food, and sex). We also show, for the first time, that discounting changes over the menstrual cycle in a pseudo-control group of 99 women on hormonal contraception. Interestingly, such women increase their discounting of sex toward the end of the menstrual phase – possibly reflecting a prioritisation of bonding-related sexual activity before menstrual onset.
Seeing you in me: Moderating role of relationship satisfaction and commitment on assumed similarity in Honesty-Humility and Openness to Experience
Authors: Liu Jie , Ilmarinen Ville Juhani , Lehane Christine M.
Published: February 2022

This study examined distinctive assumed similarity in Honesty-Humility and Openness to Experience and its influencing factors. With samples from the British Isles, China, and Denmark and with both individual and dyadic data (N = 1196), the meta-analytical results show that distinctive assumed similarity in Honesty-Humility and Openness to Experience was higher than in Emotionality, Extraversion, Agreeableness, and Conscientiousness in intimates after controlling for normativity. Also, relationship satisfaction and commitment moderated distinctive assumed similarity in Honesty-Humility and Openness to Experience, indicating that people high in relationship satisfaction and commitment perceived their partner to be more similar to them regarding those two traits relative to people low in relationships satisfaction and commitment. Implications and limitations of this research are also discussed.

Wann sind Grundschulen in „sozial schwierigen Lagen“ und was bedeutet dies für Lehrkräfte, Schülerinnen und Schüler?
Authors: Weishaupt Horst
Published: February 2022

Es gibt mehrere Ansätze, unterschiedliche Anteile der Schulen als sozial benachteiligt zu bezeichnen. Diese gestatten es nicht, Veränderungen des Anteils der Schulen in sozial schwieriger Lage zu erfassen. Deshalb werden hier Daten der IQB-Erhebungen 2011 und 2016 verwendet, um nach dem Sozial- und Migrationsstatus der Schülerinnen und Schüler den Anteil der Grundschulen in sozial schwierigen Lagen im Zeitvergleich zu bestimmen. Deutlich wird ein erheblicher Anstieg des Anteils von Schulen in sozial schwierigen Lagen innerhalb von nur fünf Jahren. Differenziert nach den Stadtstaaten sowie ost- und westdeutschen Flächenländern werden Leistungsunterschiede und Unterschiede der innerschulischen Bedingungen zwischen Grundschulen in sozial schwierigen Lagen und sonstigen Grundschulen beschrieben. Grundschulen in sozial schwierigen Lagen sind auch hinsichtlich der innerschulischen Bedingungen benachteiligte Schulen.
Carbon status of Russia and the dynamic equilibrium of the biosphere
Authors:   Institute of Soil Science and Agrochemistry of the Siberian Branch of the Russian Academy of Sciences, Naumov А.V.
Published: February 2022

The article examines the acute debatable issues of assessing the carbon status of terrestrial ecosystems. The concept of dynamic carbon balance in the biosphere is substantiated. The fallacy of the notion that terrestrial ecosystems of Russia represent an absolute sink of atmospheric carbon dioxide is shown. In the light of the new concept of dynamic equilibrium of the carbon cycle, estimates of the annual primary production of NPP, CO2 emissions from the soil surface (soil respiration) SR and carbon content in dry organic matter are considered. In modern conditions, the ratio NPP/SR~1 is an important quantitative criterion characterizing the carbon status of natural terrestrial ecosystems. The relative stability of climatic parameters is closely related to the large capacity of natural carbon reservoirs and the mechanism of systemic adaptation of the biological cycle.

Published: February 2022

Dynamics of land use are closely related with society, development activities and environment. For the sustainable management of land resource of an area, land use may act as one of the elements of conflicts which could be resolved through land use planning ensuring equitable access and right of land to the owners. The present paper attempts to assess the land use for land use planning and infrastructure development through land evaluation including risk factors. Sambhunath municipality located within Saptari district of Nepal has been used as the study area to test the issues raised. Both qualitative and quantitative methods are used for data generation and analysis. Land use changes have been analyzed for the period 1986 to 2017. Potential land use zones have been identified through land suitability analysis using MCE-AHP and in relation to the risk factors such as flood, soil erosion, landslide, and fire. The infrastructure development plan has been allocated based on land use suitability index maps and planning guidelines. Land use projection have been made through Cellular Automata technique, and land use plans have been developed based on projected land use and optimized through SWOT analysis. Implementation strategy is developed based on legal framework to implement land use plan at local level. The land use change patterns are characterized by the increase of agriculture and built-up area and the decrease in areas under forest cover and water body simultaneously. Altogether 27 different criteria are identified and applied in land use suitability evaluation. Risk prone area is found mostly surrounding to the foot of Chure hill and along Khando river. Almost 46% of the total areas have been planned for future agriculture land use followed by residential, commercial, industrial and public uses which are 201 ha, 26 ha, 3ha, and 345 ha respectively. An implementation strategy has been devised to empower and enforcement for compliance of land use zone together with guidelines for outlined development activities.

Published: February 2022

Ramaroshan of Sudurpaschim Province is rich in biodiversity, and ecologically distinct but scientifically unexplored rural and remote area of Nepal. There is a holy perennial Kailash River as a lentic and aesthetically well-known Ramarosan Lake Cluster (Batula Lake) as a lotic environment located in the region. This study has analyzed and then characterized the water quality status of both the lentic and lotic environments. The physicochemical parameters such as temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), and major ions were analyzed for the hydrochemical characterization. The results revealed that the dominancy orders of cations and anions of the study area were found to be Ca2+ > Na+ >Mg2+ > K+ > NH4+ and HCO3- > Cl- > SO42- > PO43- > NO3-, respectively. The concentrations of most of the parameters were relatively higher in the Kailash River than the Batula Lake except for the SO42-, PO43- and NH4+. The water facies displayed the Ca-HCO3 type indicating the calcium carbonate type of lithology in the area. Additionally, the carbonate weathering is also higher than the silicates and evaporates. Similarly, the source controlling mechanisms indicated that the hydrochemistry of the Ramaroshan area is determined by both geogenic weathering and precipitation. Water quality assessment for irrigation parameters confirmed its suitability for irrigational purposes. The finding of this study could be the baseline dataset for assessing the future status and management of water resources of the Ramaroshan area.

Naica’s ”Cueva de los Cristales” was discovered in 2000. It has been considered particularly interesting for its beauty and the challenges it poses to crystallography. This article focuses on the study of the wall-selenite interface by various techniques, particularly X-ray diffraction (XRD), scanning electron microscopy (SEM), with emphasis on micro-X-ray fluorescence (micro-XRF) and micro-X-ray absorption near edge structure (micro-XANES). The main phases calcite, quartz, goethite and montmorillonite were identified by XRD, as well as the association of crystalline and amorphous minor and trace phases of Zn, Mn, Cu, As and Pb. The latter were identified in micro-XRF maps and micro-XANES spectra. The results for the morphology and the chemical description of the crystal-wall interface may contribute to propose a nucleation and growth mechanism for Naica megacrystals.

Published: February 2022

Piston drilling pumps, the main part of which is hydraulic, are widely used in the process of drilling wells for oil and gas. It determines the efficiency, reliability and durability of the pump in general. In recent years, the depth of drilling wells in Ukraine and abroad has increased, which requires the use of more powerful drilling pumps and is accompanied by increased operating pressures. The load on the hydraulic part increases, and this has a negative effect on the operation of the valve assemblies of the pump. Valves are one of the most responsible and fast-wearing units in the hydraulic part of the drilling pump. The frequency of maintenance of the pump de-pends on their resource. Analysis of drill pump valve designs and operating conditions showed that despite the wide range, their service life remains quite low. Therefore, there is a need for further studies of valve designs and their moderniza-tion. It is known that one of the reasons that leads to the destruction of the valve parts is the ingress of abrasive particles from the flushing fluid into the gap between the plate and the seat. This accelerates the destruction of the cuff first, and then the valve. To avoid this phenomenon, it is proposed to use an improved valve design, the inner surface of the sealing sleeve of which is cylindrical. The cuff of this design will be deformed in the vertical direc-tion, without forming a gap with the valve plate. To confirm the operability of the proposed design of the cuff, a three-dimensional model of the valve was built and a simulation study was conducted. The results of this study confirmed the effectiveness of this design and a significant increase in the life of the valve assembly.

The scientific basis for the development of working materials from waxy highly filled composites for FDM 3D printing using is not yet sufficiently developed. The need to develop such composites is due to the fact that highly filled waxy composites, on the one hand, have low 3D printing temperatures, and on the other hand, the fact that the waxy substance has a low ash content and is completely removed during annealing and subsequent sintering of the residual framework from the filler. Therefore, in this work, the influence of the binder content on the physical and mechanical properties of composite materials such as metal powder - waxy substance in the ratio of metal to waxy substance, as 50/50, 60/40, 70/30, 80/20 % (by volume), as well as the shape change of composite samples when they are heated at a temperature from 61 to 230 °C. Carbonyl nickel and carbonyl iron were used as metal powder, and beeswax and paraffin were used as a binder. It was found that the developed surface of particles significantly affects the density dependence, the microhardness and compressive strength of composites from the binder content, the actual density of the composite samples after pressing is less than the calculated by the additivity formula with the binder content up to 40 % (by volume) and only with an increase in the binder content to 50 % (by volume) does the actual density approach the calculated additive; the developed surface of nickel particles several times increases the strength of the composite in comparison with iron at the same binder content, at the same time, the dependences of the microhardness differ significantly: on Ni-wax samples, it tends to decrease with an increase in the wax content, and on samples Fe-paraffin - to an increase, which is due to the influence of such phenomena as adhesion and cohesion, mechanical adhesion. The level of strength of composite samples with a binder content of 40-50 % (by volume) is sufficient so that they do not collapse not only in 3D print head The resulting experimental data can be extended to other similar systems when creating working materials for FDM 3D printing based on carbonyl nickel and iron powders.

The results of experimental studies of the technological process of the inertial safety clutch for two options and two cases of determining the braking torque of the output shaft: a combination with a reverse and a parasitic gear; combinations without reverse and  with parasitic gear; combinations with reverse and without parasitic gear; combinations without reverse and without parasitic gear are given. The functional nature of the change in the brake torque of the output shaft has been investigated. The plan of the factorial experiment was chosen, the limit intervals
or limit levels of variation (initial, or upper and final, or lower limit of change) of each individual input factor were set: the speed of the input shaft of the inertial safety clutch and the gear ratio. A histogram of non-approximated experimental data of the braking torque of the output shaft of the inertial safety clutch is constructed. On the basis of comparisons and analysis of graphical constructions of the diagram of the change in the braking torque of the output shaft of the inertial overload clutch for various combinations, it can be stated that: the process of operation of the inertial overload clutch using the reverse and with the parasitic gear provides a slight increase in the braking torque of the output shaft of the inertial overload clutch in on average by 3%; the process of operation of the inertial overload clutch without the use of reverse and with a parasitic gear practically does not provide an increase in the braking torque of the output shaft of the inertial overload clutch. On the basis of a comparative analysis, reasonably rational parameters of an inertial safety clutch at which its "stop" mode of operation is achieved.

The work analyses the problem of high-quality cooling of molds for obtaining castings from thermoplastics, which are characterized by significant coefficients of volumetric and linear thermal expansion, the ability to compact in the molten state. The change in the volume of the thermoplastic melt and, accordingly, product quality characteristics primarily depend on the mold temperature mode. The latter provides for the required temperature, heating rate and cooling rate of the mold. In turn, these parameters partially determine the pressure of the thermoplastic in the working volume. The heating rate and cooling rate of the mold are primarily determined by the dimensions and configuration of the channels of the mold cooling system. Experimental improvement of the design of the cooling system channels requires significant expenditures of materials, time and money. The authors of the article proposed a method for optimizing the design of a mold cooling system using computer technologies for 3D modeling in the Solid Works environment and thermodynamic studies using the finite element method in the ANSYS program. In the first part of the work, several versions of virtual models of the main structural parts of a mold for casting a thin-walled real product from a thermoplastic were created: dies, punches and mounting plates. At the same time, the main structural dimensions of the mold were maintained and necessary structural simplifications were made (inscriptions, stamps were removed) in order to save resources when performing thermodynamic studies. The differences between the models were in the different configurations of the water cooling channels - straight, V- and W-shaped. These studies were carried out in the Transient Thermal package. The main task of these studies was to determine the nature of the propagation of thermal fields in the volume of the matrix. Initial data for research - mold temperature, temperature and volumetric supply of coolant in all experiments are the same. The results of computer studies have shown that in a cooling system with W-shaped channels, the cooling of a thermoplastic casting occurs most uniformly, as evidenced by the configuration of thermal fields in the die and the punch. Based on research materials, a mold was made. Test results have confirmed efficiency of computer research in plastic molding technologies.

Published: February 2022

After analyzing the main trends, it was found that sheet metal stamping is widely used in many fields of mechanical engineering. And the destruction of the working parts of the stamp in serial or mass production significantly affects productivity. In the course of work punches are exposed to high power loading therefore they are made of wear-resistant steel with the increased durability and hardenability. But like any tool with a long load, the punch and die are almost always accompanied by the combined action of two destructive processes - wear and fatigue, and the service life is limited by the number of strokes. The influence of the properties of the punch material by the finite element method for punching a hole made of sheet material on the stamps of cold sheet stamping is investigated in the work. The study was performed fifteen times for five different materials. The punch was subjected to a load from changes in sheet thickness where the maximum stresses of possible displacements as well as deformations were monitored. Having the character of influence on stability of the tool. During long-term operation of the stamp there is a large concentration of stresses in the weakest zone of the punch, which causes the lower part to wrinkle, which creates forces acting on the axis of the punch. Such deformations usually lead to a reduction on one side of the gap between the punch and the die and encourage an increase in friction forces. The gaps that depend on the mechanical properties and thickness of the material, as well as the mode of operation of the press - the number of double strokes of the slider per minute. The dependence of the influence of the material of the punch and the gap between the punch and the matrix on the quality of parts and the performance of the stamp is considered. The maximum possible number of punches was determined, the calculation and analytical analysis of the tool stability from material change to sheet thickness was performed. As well as stability depending on the hardness of the tool material. The obtained research results were analyzed, substantiated and described in this article, as well as recommended to use the influence of the properties of the material of the punch in the design of dies.

Published: February 2022

Ukrainian physical terms – names of static features have been analyzed in the article. Partial word-forming meanings of derivatives within physical terminology have been discovered. Structural types of word-forming bases of proper Ukrainian and loan derivatives have been analyzed. Nature of interaction among different word-forming types within researched word-forming category has been considered. The conducted research leads to the following conclusions.

The formation of Ukrainian physical terms – names of static features is carried out in the same way as in common language word - forming processes. This process is characterized by such regularities: tendency to concentration, generalization of main derivative types, limitation of their number in the researched derivative category (only two types of proper Ukrainian adjective terms: with suffix - ість and one type of loan terms with suffix - -изм/-ізм- are productive in physical terminology).

Published: February 2022

This article presents a comprehensive linguistic analysis of intonation with a systematic identification of the most important functions and features of the phonetic design of this phenomenon based on the American film "Clueless". Due to the fact that the action of the film takes place at school and touches upon the problem of social groups among young people, the characters' speech is filled with jargon and speech phenomena accompanying intonation (in particular, Vocal Fry, a discursive marker like), and demonstrates the use of this intonation.

It is important to note that the index or personal-social function of intonation is of the greatest value in this study, i.e. “The ability of intonation to identify the speaker's personality”.
CONCEPTION OF ETHOS IN THE PHILOSOPHY OF PLATO AND ARISTOTLE
Authors: Ganieva A.
Published: February 2022

The article discusses the Ethos as one of the most interesting applications of ancient Greek philosophy as a musical-ethical term. Ancient Greek philosophers constantly used music as a tool of ethics not only in philosophy, but also in all historical music, and this can be called a developmental phenomenon. Ethos is an event in the history of civilization, and in this context, the combination of music and ethics in human activity gives its essence. The understanding of ethics by Plato, like most Greek philosophers, is aimed at nobility, free citizens who are not slaves. And the concept of Aristotle's musical esthetics is based on a clear relationship between esthetics and ethics (worldview), theory and practice.
