Is Personality Pathology Ego-Syntonic? Self- and Meta-Perception of Maladaptive Personality Traits
Authors: Sharpe Brinkley M. , Sleep Chelsea E. , Carter Nathan T. , Lynam Donald R. , Miller Joshua D.
Published: September 2023

Research has challenged the assumption that personality pathology is “ego-syntonic” or perceived favorably and consistent with one's self-image. The present study employed a community sample (n = 401) to examine relations between self-rated maladaptive personality and liking of maladaptive traits in self and others as well as meta-perception of personality pathology (i.e., how likable participants believe others find maladaptive traits). In general, individuals with higher self-rated maladaptive traits provided higher ratings of the likability of these traits in themselves and others. However, as hypothesized, comparison of liking ratings for high scorers and the rest of the sample revealed that individuals who score high on most pathological personality traits do not “like” these traits (or rate others as “liking” them) but simply dislike them less. Results support a dimensional view of ego-syntonicity.

Published: September 2023

Because the sophistication of tool use is vastly enhanced in humans compared with other species, a rich understanding of its neural substrates requires neuroscientific experiments in humans. Although functional magnetic resonance imaging (fMRI) has enabled many studies of tool-related neural processing, surprisingly few studies have examined real tool use. Rather, because of the many constraints of fMRI, past research has typically used proxies such as pantomiming despite neuropsychological dissociations between pantomimed and real tool use. We compared univariate activation levels, multivariate activation patterns, and functional connectivity when participants used real tools (a plastic knife or fork) to act on a target object (scoring or poking a piece of putty) or pantomimed the same actions with similar movements and timing. During the Execute phase, we found higher activation for real versus pantomimed tool use in sensorimotor regions and the anterior supramarginal gyrus, and higher activation for pantomimed than real tool use in classic tool-selective areas. Although no regions showed significant differences in activation magnitude during the Plan phase, activation patterns differed between real versus pantomimed tool use and motor cortex showed differential functional connectivity. These results reflect important differences between real tool use, a closed-loop process constrained by real consequences, and pantomimed tool use, a symbolic gesture that requires conceptual knowledge of tools but with limited consequences. These results highlight the feasibility and added value of employing natural tool use tasks in functional imaging, inform neuropsychological dissociations, and advance our theoretical understanding of the neural substrates of natural tool use.

SIGNIFICANCE STATEMENTThe study of tool use offers unique insights into how the human brain synthesizes perceptual, cognitive, and sensorimotor functions to accomplish a goal. We suggest that the reliance on proxies, such as pantomiming, for real tool use has (1) overestimated the contribution of cognitive networks, because of the indirect, symbolic nature of pantomiming; and (2) underestimated the contribution of sensorimotor networks necessary for predicting and monitoring the consequences of real interactions between hand, tool, and the target object. These results enhance our theoretical understanding of the full range of human tool functions and inform our understanding of neuropsychological dissociations between real and pantomimed tool use.

Published: September 2023

Monitoring and assessing the phytosanitary status of forests is a crucial activity in forest protection field, and the use of satellite remote sensing has become increasingly prevalent in this regard. Satellite images offer valuable information in terms of time and space, particularly through the analysis of vegetation and biophysical indices. Within this context, the aim of the study was to explore the potential of satellite remote sensing methods to monitor and assess the extent of tree defoliation caused by the gypsy moth (Lymantria dispar). The research study was focused on a forest situated in the Oltenia region of Romania, which experienced a gradation period for the defoliator L. dispar between 2018 and 2020. To determine the extent of defoliation caused by L. dispar in 2020 and 2021, a rectangular network consisting of 70 one-hectare sample areas was implemented. Each sample area had a square shape with a side of 100 m. In each corner of the sample areas, sub-sample circles with a radius of 12.62 meters were established, in which visual observations regarding the defoliation levels were conducted. The study involved a comparison between thematic maps derived from ground observations and those based on specific remote sensing indices derived through the processing of Sentinel 2 satellite images, of the Ciuturica forest area during the years 2020 and 2021. The research study indicated that the canopy water content (CWC) index was the most suitable for assessing defoliation caused by L. dispar. Furthermore, the study highlighted that remote sensing methods could be very effective and easily applicable, complementing the field ground-based efforts in monitoring and assessing the impact of L. dispar infestations.

Published: September 2023

Osteoporosis (OP) is a systemic bone disease in which bone density and quality decrease and bone fragility increases due to a variety of causes, making it prone to fractures. The development of OP is closely related to oxidative stress. Uric acid (UA) is the end product of purine metabolism in the human body. Extracellular UA has antioxidant properties and is thought to have a protective effect on bone metabolism. However, the process of UA degradation can lead to intracellular oxidative stress, which together with UA-induced inflammatory factors, leads to increased bone destruction. In addition, UA can inhibit vitamin D production, resulting in secondary hyperparathyroidism and further exacerbating UA-associated bone loss. This review summarizes the relationship between serum UA levels and bone mineral density, bone turnover markers, and so on, in the hope of providing new insights into the pathogenesis and treatment of OP.

Individual personality traits are powerful determinants of behavior, and they can profoundly influence consumer decisions as a comprehensive understanding of consumer personality traits. Their role in decision-making can improve the predictability of consumer-related behavior. In this study, data on consumers’ preferences and personality traits were collected through questionnaires using the Wood Furniture Product Characteristics Consumer Preference Scale and the Big Five Personality Inventory Simplified. Bivariate correlation analysis and stepwise multiple regression analysis were used to investigate the relationship between the Big Five personality traits (neuroticism, extraversion, openness, agreeableness, and conscientiousness) and wood furniture product characteristics consumer preferences. Correlation analysis indicated that neuroticism was correlated negatively with wood furniture product characteristic consumer preference scores. Extraversion, agreeableness, and conscientiousness were correlated positively with wood furniture product characteristic consumer preference scores. There was no correlation between openness and consumer preference. Regression analysis indicated that neuroticism, extraversion, agreeableness, and conscientiousness predicted wood furniture product trait consumer preferences. Overall, assessing personality traits can help provide insight into the psychological and behavioral characteristics of consumers when purchasing wood furniture products, allowing for a more comprehensive understanding of market demand and more effective marketing and product positioning strategies.

Context. The radar means of outer space control are monofunctional systems, despite their potential multifunctionality. To ensure the effective implementation of target functions, only some of the total number of potential functions are used, other existing functions are not studied and as a result, don’t used. The target functions of most existing domestic and foreign radiolocation stations on space control RLS SC are practically reduced only to the control of space objects in different orbits. The obtained information is not fully used, so the new target doesn’t form. As the history of the development of defense complexes shows, in most industrialized countries there are examples of the use of military developments for civilian purposes (spin-off) and civilian developments for military purposes (spin-on). As a result of these synergy processes emphasis on the strategy of double technologies and double innovation increased. Objective. The aim of the work is to study the possibility of introducing an ionospheric channel into the domestic radar station 5N86 Dnipro (Hen House) and expanding its intended use by using most of its functional systems to implement the ionosphere control function. Method. The paper uses a comparative analysis of the main functional systems and technical characteristics of the 5N86 Dnipro radar and non-coherent scatter radars (PHR) of the global ionosphere control network. Results. The main characteristic features of the RLS 5N86 are analyzed and, taking into account the characteristics of the signals, the possibility of using the multifunctionality of the radar to form a new target function for monitoring outer space is substantiated. From an applied point of view, a number of specific scientific and practical solutions are given, aimed at the realization of dual-purpose technology in the implementation of the ionosphere control function by a radar station - both for solving the problems of increasing the own efficiency and for the interests of fundamental science. It is shown that the creation of new target RLS is based on both the use of already existing systems and the introduction of new ones. The importance of the scientific task on the implementation of the ionosphere control function and the possibility of integrating into the global ionosphere control network is substantiated. Conclusions. The presence of scientific and technical developments and the practical experience of the domestic RLS SC developer makes the new target function realization absolutely realistic. The implementation of the double-purpose technology will ensure an effective solution for both applied and fundamental scientific tasks.
A Cultural and Symbolic Aspect of Memorial and Burial Loci (In the Realities of the Russian-Ukrainian War)
Authors: Taran Olena
Published: September 2023

The events of the russian-Ukrainian war, especially the last year and a half of its active phase, show how death and dying strongly fixed in space and place. The ability of spaces and places associated with death (cemeteries) and dying (places of death – spontaneous memorials) to evoke the deepest memories and intense emotions are a testament to the power of place and a reminder that the power of symbolic space is in emotion, not function. One of the expressions of collective grieving is memorial sites, whose choice has a deep symbolic meaning. Through careful anthropological analysis of burial sites and memorial sites, the intense emotional experiences associated with death, including grief, bereavement, and reminiscence, can be understood. Funeral and memorial practices are mediated by several spaces – the body (corporeal), the place of death/dying, the morgue, the cemetery, the crematorium, the memorial of memory, the virtual space of the cyber world – the networked martyrologists. The conflict arising from the ongoing performance and recording of memory in public space is reflected in debates about expressions and markers of private grief in public spaces and related disputes about what constitutes a ‹sacred› place. The tragedies of civilian deaths during shelling are part of what are becoming new ritual forms and memorials, constructing a permanent memory of the dead in the material landscape of lived space. The tradition of designing memorials during the russian-Ukrainian war creates a «register of sacred history» – a set of shared historical experiences and views that define and unite the community. Processes of memorialization after a tragic death, which are increasingly taking place in public, are becoming medialized and are used by the state as a political tool. The nature of the memorial landscape creates a specific style of communication, in which the entire society is engaged in spatial dialogue.
Volodymyr Bakhtov’s Creativity in the Context of the «New Archeology» of the Late 1980s to 2000s
Authors: Sklyarenko Halyna
Published: September 2023

The article is dedicated to the work of one of the interesting contemporary Ukrainian artists – Volodymyr Bakhtov. His creative path began in the mid – 1970s in the field of graphics, in which the artist bypassed the influence of socialist realism, immediately defining his main theme: the history and culture of Southern Ukraine. His series of etchings, which were awarded numerous international and domestic awards, metaphorically reproduced and figuratively interpreted the layering of cultural epochs that influenced the culture of the region. At the end of the 1980s, he turned to the contemporary artistic practices – land art, performance art, art objects, and later – to original light actions in the author’s technology «geliograffiti», which together are part of the «new archeology» that marked an important trend in contemporary art. Its emergence is connected with the idea of «revision» of culture, analysis of its experience. Similar searches are directed to the expansion of the cultural space, actualization of its historical layers in the public consciousness. The theme of V. Bakhtov’s «artistic research» was the antique heritage of the Northern Black Sea region, in particular the ancient Greek city of Olbia, which is now an archaeological reserve, and the disappeared monuments of architecture and history of the region. The artist’s long-term creative project in his own figurative way «reconstructs» the ancient heritage within the culture of Ukraine, connects it with the great European oecumen, emphasizes the role and importance of the ancient cities of the Northern Black Sea region in the formation of the Ukrainian cultural space. V. Bakhtov’s works represent artistic research and reconstruction of cultural and natural features of the historical landscape, thus combining archaeological and ecological intentions, and the language of modern art makes it possible to emphasize the special dialogic nature of the author’s expression, actively involving the viewer in participation. The artist’s work synthesizes historical-research and figurative-metaphorical components.
The Premiere of the Ballet «Dante» on the National Opera of Ukraine` Stage
Authors: Kovalenko Yeva
Published: September 2023

The article describes the premiere of the ballet «Dante», which was performed at the National Opera of Ukraine in June 2021. The director of the ballet, dedicated to the 700th anniversary of the death of the outstanding Italian Renaissance humanist poet Dante Alighieri, was Yaroslav Ivanenko, a graduate of the Kyiv State Choreographic School who began his dancing career at the National Opera and has worked abroad since 1996, including as a soloist with the Hamburg Ballet under the direction of John Neumayer in 1998-2010. Yaroslav Ivanenko has extensive experience in ballet mastery, his choreographic productions have been repeatedly honoured with prestigious awards. Since 2011, he has been heading the ballet troupe of the Kiel Opera House in Germany, where he has staged many ballets in various choreographic styles. The staging of Dante at the National Opera of Ukraine was an interesting experience both for the Kyiv ballet troupe, which got acquainted with new choreographic vocabulary, and for the choreographer himself, for whom the creation of an original full-scale performance based on Dante’s biography and works was a new stage in his development, compared to working on plotless ballets and interpreting well-known classical plots. In an interview with the author of the article, a former ballerina of the National Opera of Ukraine, Yaroslav Ivanenko revealed the details of the work on the staging of Dante on the Kyiv stage, the creation of the director’s concept of the performance, the musical composition, which harmoniously combines works by classical and contemporary composers, the choreographic text, and shared his thoughts on the prospects for the development of ballet art and culture in general. In particular, the ballet master, who has also staged «Romeo and Juliet» and « Evgeny Onegin», analyses the images of these classical works in the context of the present, and finds semantic parallels with the story of Dante’s ideal love for Beatrice, whose image inspired the artist to create sonnets and poems that became part of the treasury of Italian Renaissance poetry.
Civil Sphere and Transitions to Peace: Cultural Trauma and Civil Repair
Authors: Alexander Jeffrey C.
Published: September 2023

What are the conditions for establishing solidarity after a period of intensive and divisive social conflict — what Kant called a cosmopolitan constitution? In this essay, I argue that such a widened solidarity depends on establishing a relatively independent civil sphere, the effective functioning of whose institutions depend, in turn, on a shared sacred discourse of civility. To speak such a shared language, however, requires much more than engaging in speech acts. It depends upon a deeply emotional and highly symbolic process, one in which public performances of reconciliation create new structures of feeling and identification. This theoretical argument is elaborated empirically with reference to post-Holocaust Germany, post-Franco Spain, and post-Apartheid South Africa.
The youth of Ukraine in the period of social turbulence 2019–2021
Authors: Kukhta Myroslava , Soboleva Natalia
Published: September 2023

The article considers the main problems of the situation and development of youth in Ukraine during the period of social turbulence 2019–2021. Youth is the main resource of society and the main component of human capital, which is being fought for in developed countries. In recent years, Ukraine has faced the loss of this resource due to depopulation and migration. The problems of young people, which emerged in the pre-war years, are now becoming unprecedentedly acute. The first step on the way to a solution is an in-depth analysis of the key problems and features of young people's lives. The authors analyze the spheres of education, employment and work, housing conditions, consumption and leisure, health practices, and social interactions of Ukrainian youth. Special attention is drawn to the differences in ways of life constructing by young men and women, considering that the main areas of life are determined by gender differences in life opportunities. In addition to gender differences, the age subgroup is also a determinant. The most noticeable difference in value orientations and outlook is that the younger they are, the more open they are to change and seek self-affirmation. The youngest subgroup was also the most optimistic, regardless of economic level, and the least religious. In general, in recent decades there has been a diversification of lifestyles thanks to the emergence of new economic, informational, cultural, and political perspectives. The empirical basis of research is a series of data of domestic and foreign studies: the State Statistics Committee of Ukraine on the sex-age distribution of the population of Ukraine, the annual monitoring study of Ukrainian society, the Info Sapiens survey for the International Research and Exchanges Board (IREX), the ninth periodic report of Ukraine on the implementation of the Convention of the United Nations Organization, the study of Ukrainian women entrepreneurs, the study of the sociological group "Rating", the report "World Values Survey–2020. Ukraine", the report on the situation of the youth of Ukraine "Youth on the labor market: 21st century skills and career building", a representative sociological study of the situation of youth in Ukraine.

Using methods of multidimensional analysis to research decision making in academic career choice
Authors: Sereda Pavlo , Maltseva Kateryna
Published: September 2023

The decision that students make regarding his or her further education or professional career is a complex process driven by multiple different factors. On the global scale, this research direction represents an important strategic tangent, given the significance of the universities in the formation of virtually all aspects of one’s life after graduation. It is equally crucial in the Ukrainian context, considering the educational reforms that are currently taking place in our country. As motivation to make a choice and embark on a particular career trajectory can be informed by different sources and is thus a multifactorial entity, so researching factors that affect academic career choice should accomodate multiple dimensions. To optimize the analytical procedures and to increase the informativeness of the results in our survey we employ methods of multidimensional analysis to explore and explain various aspects of decision making that can influence one’s choice of the institution for further education. To elicit the determinants of the university choice and to illustrate the effects of various factors in different domains of career choice, we use the cognitive self-report data collected from the NaUKMA undergraduates in Spring 2019. The results suggest that in students’ perception institutional characteristics of the NaUKMA, social atmosphere, academic climate and personal features of a student emerge as distinct factors. In the set of factors, the institutional characteristics were subdivided into the evaluation of the quality of the received education and strategic argument against applying for a postgraduate degree at the NaUKMA. Social atmosphere and academic climate, in their turn, split into social atmosphere, academic climate and being socially connected with individuals currently enrolled as MA students. Personal features were further subdivided into career values, attitudes toward one’s studies and attitudes towards the MA programmes. Positive evaluation of NaUKMA’s institutional characteristics has a positive correlation with one’s intentions of joining the programme and continuing one’s studies at NaUKMA, and a negative correlation with planning to apply to MA programmes abroad or elsewhere in Ukraine. Planning to avail of the international mobility programmes had a positive effect on choosing to join the MA programme at NaUKMA.
Health beyond clinical protocol: institutional traps and limitations of modern medicine
Authors: Kandrychyn Siarhei
Published: September 2023

The article is aimed to describe the ineffective health care mechanisms and find ways to overcome them. Some variants of institutional dysfunctions (or institutional traps) in medical practice are considered. The resort to natural methods of healing and self-healing is regarded as a way to overcome various institutional dysfunctions. The work combines several qualitative methods: a non-standardized survey of experts (doctors), included observation (25 years of work as a doctor and independent use of natural healing methods for the past 12 years), and analysis of documents, literary sources and messages on the topic of self-healing in relevant Facebook groups. The themes of the talks with doctors were health self- management and alternative healing practices (intensive physical exercises, medical fasting, and breathing exercises). During conversations with the doctors found that only some senior doctors have positive experience of using therapeutic fasting and breathing exercises (both personal and clinical), and young doctors who have been working in medicine for over 10-20 years are not familiar with these methods ("because this treatment is not carried out according to the approved clinical protocols”, and “we treat according to modern protocols"). The most problematic points of the use of such health practices and the reasons for their increase in society are discussed. It is concluded that both in the institutional and ideological aspect, the essential component of the public health institute should be outside the scope of official medicine, which is aimed at the use of medicinal and high-tech means of treatment and prevention.
Assessment of changes in productivity and limitations in forcing movement when increasing the volume of blast furnaces
Authors: Kryachko G. Yu. , Sigarev Ye. M.
Published: September 2023

The selection of the useful volume of new or reconstructed blast furnaces is an urgent task for both manufacturers and designers; therefore, the assessment of the technological capabilities of furnaces of different volumes has always been of interest from both a practical and a theoretical point of view. The purpose of the presented work is the selection of the most representative indicators, with the help of which a comparative assessment of the operation of furnaces of different volumes is possible, the evaluation of the operation of furnaces in the conditions of planned and market economies, as well as an attempt to determine and classify the factors limiting the forced operation of furnaces of increased volume. It is shown that the use of indicators calculated per unit area furnace is not appropriate, since area furnace is not the main size furnace. The main size is full volume furnace, which determines design unit and amount of capital costs for its construction. Specific productivity indicators calculated per unit volume furnace similarly depend on the height furnace and adequately reflect performance of furnaces of different volumes. The indisputable advantage of compact blast furnaces with a useful volume < 1500 m3 in comparison with furnaces of larger volumes is shown, which indicates imperfection of a simplified approach to evaluating performance of furnaces based on the concepts of balance and gas dynamic components, since it is difficult to take into account all the components when determining these components influencing factors. Factors limiting process intensification in blast furnaces of medium and large volumes have been established and classified. The main external factors are the quality characteristics of coke, iron ore materials and blowing, more specifically, hot strength of coke, richness of raw materials in iron and the ability of air blowers to provide blowing with required degree of compression. The main structural solutions to overcome significant limitations in operation of furnaces with a useful volume > 1500 m3 are a rational profile, ratio of output cross-section of air nozzles and cross-section furnace, as well as the use of coneless loading devices.
The investigation of the thermal performance of the graphitized hollow electrode in the "ladle-furnace" with the supply of neutral gas
Authors: Ruban V. O. , Stoianov O. M.
Published: September 2023

The article presents an analysis of heat transfer efficiency from an electric arc discharge formed in the sub-electrode zone to a metal bath under different operating conditions of the “ladle-furnace” (LF). A numerical modeling methodology has been developed, and the obtained data have been analyzed to determine the heat transfer efficiency with the supply of neutral gas through a graphitized hollow electrode (GHE). The objective of this study is the numerical modeling of the influence of changing the geometric parameters of the metal bath cavity formed by gas injection through the channel of the graphitized hollow electrode on the heat transfer efficiency from the electric arc to the metal bath at different thickness of the slag cover in the “ladle-furnace”. Research methods. Numerical modeling of the heating of the metal bath was performed on a developed 3D model of a steel ladle with liquid metal and a cavity zone formed under the action of an electric arc and gas supplied through the channel of the graphitized hollow electrode. Heating was conducted under different geometric parameters of the cavity and varying heights of the slag cover. The obtained data were analyzed, indicating the advantage of using the graphitized hollow electrode with gas supply through its channel compared to a conventional electrode. Results obtained. The share of heat absorbed by the slag and metal under the conditions of using a conventional electrode and a hollow electrode with gas supply through its channel was determined. The influence of the parameters of the reaction zone formed under the GHE on the heat transfer from the electric arc to the metal bath was determined, with maximum temperature increase values of the metal amounting to 0.6 ºC/min. Scientific novelty. New data were obtained regarding the influence of neutral gas supply through GHE on the amount of heat transferred to the metal by convection, and indicators of the heat flux density from the electric arc to the metal cavity in the sub-electrode zone were determined. Practical significance. It was determined that increasing the area of the metal cavity by supplying gas through the GHE channel improves the heat transfer from the electric arc to the metal bath. Meanwhile, increasing the thickness of the slag cover reduces heat losses to the furnace atmosphere. The carried out research provided important data regarding the thermal performance of the "ladle-furnace" in the sub-electrode zone, which can be further utilized for process optimization.

The article is devoted to the development and industrial mastering of technological processes of particularly deep desulphurization of cast iron (sulphur content ≤ 0.002 %) by magnesium mono-injection in ladles of various sizes. The paper presents the results of research on the development of technologies for extra deep desulphurization of cast iron by mono-injection of granular magnesium, which was carried out at modern automated cast iron desulphurization and slag rolling complexes. The work was carried out jointly by Ukrainian and Chinese specialists in China at Wuhan Steel Plant No. 1 using 110-ton ladles and in Taiwan at CSC Steel Plant No. 2 using 300-ton ladles. The proven technological parameters of the cast iron desulphurization processes using granular magnesium injection with tuyeres with evaporation chambers at Steel Plant No. 1 of Wuhan Steel and double-nozzle tuyeres at Steel Plant No. 2 of CSC Concern ensured the required processing cycles, reliable and technological magnesium injection and its absorption efficiency. It was found that the degree of desulphurization of cast iron is up to 99 % of treatments and the final sulphur content in cast iron is up to 0.0002 %, with the total estimated degree of magnesium absorption into sulphur, residual magnesium and deoxidation of cast iron being ~95 %. It has been established that an important technological technique that increases the stability of the achieved processing parameters is the adjustment of the ladle slag composition, which was carried out by adding waste granular lime in the amount of 1.0-2.0 kg/t of cast iron and did not require significant costs. The results of industrial cast iron treatments were analysed and nomograms of the dependence of specific magnesium consumption on the initial sulphur content for tuyeres of various designs were constructed. The developed processes are economically justified for use in the practice of preparing cast iron for conversion.

An analysis of the state of foundry production in Ukraine is presented. The foundry industry of Ukraine in the 21st century significantly reduced its production indicators, which is due to the influence of such factors as the stagnation of industries that consume metal castings, as well as a decrease in exports. This situation has been negatively affected by the COVID-19 pandemic, as well as the global foundry industry, due to a decrease in demand for castings from end manufacturers. It was predicted that positive developments should be expected in the near future. However, russia's attack on Ukraine on February 24, 2022 made a significant correction in the development of the global economy, and, accordingly, in the functioning of the world foundry industry. Ukrainian companies in the foundry industry felt the impact of the war, some of them suffered partial destruction of their production premises. Large foundry enterprises of Ukraine are mostly located in the south-eastern regions, which were the most affected by hostilities. At the same time, in order to reflect the real situation in the foundry industry of Ukraine, it is advisable to organize the collection of real data regarding the production of castings from various alloys in the country, as well as regarding the export and import of foundry products. This will make it possible to make effective decisions regarding the program of modernization of the industry and the development of industries that consume domestic metal castings. Ultimately, this will help increase the competitiveness of Ukrainian products and increase revenues to the budget of Ukraine. To assess the direction of development of foundry production in advanced countries of the world, the statistical data of the leading countries regarding the production of castings and in more detail such countries as Poland, Germany and the USA are given. The structure of cast products produced in the world is in constant dynamics and there is a constant change in the ratio of the volumes of castings produced from various alloys. Recent years have been characterized by a tendency to reduce the production of castings from steel and gray iron with a simultaneous increase in the share of castings from highstrength cast iron and aluminum alloys.
Family firms in the maelstrom of international market entry and innovation – Can socio-emotional wealth (SEW) and entrepreneurial orientation (EO) be reconciled?

I examine the relationship between the internationalisation of family firms and innovation. After the review of the relevant literature, I group together the narrow research topics addressed in the literature, which largely confirm the positive relationship between the two categories. Moreover, I demonstrate a theoretical framework which, according to the literature, can be implemented to put socio-emotional welfare and entrepreneurial orientation, which are restraining the internationalisation of family firms, on a common path, so that they can contribute to enhancing the innovative and international performance of family firms in a mutually supportive way.
New record of Azurina intercrusma (Evermann & Radcliffe, 1917) (Ovalentaria incertae sedis, Pomacentridae) and confirmation of Scuticaria tigrina (Lesson, 1828) (Anguilliformes, Muraenidae) in the Galápagos Islands

Herein we provide the first published records for Azurina intercrusma and a correction of previous Scuticaria tigrina records within the Galápagos Marine Reserve. The former had not previously been reported north of the southern Ecuadorian coastline and represents a significant step outside of its known distribution for this cold-water species. Scuticaria tigrina had been mentioned in previous literature as present, but its inclusion appears to have been in error; we confirm its presence as a vagrant and provide evidence of live observations in different parts of the archipelago.

Про можливість створення кріогенних гелієвих і водневих установок високої продуктивності та ефективності на основі машин динамічного принципу дії
Authors: Лавренченко Г.К.
Published: September 2023

При створенні кріогенних гелієвих (КГУ) та водневих (КВУ) установок високої продуктивності доводиться вирішувати складну проблему компримування великих кількостей таких легких газів, як гелій та водень. Компресори таких кріогенних установок повинні забезпечувати значні ступені підвищення тиску, відрізнятися високою надійністю, малими габаритами та масою. Компресорні машини об'ємного принципу дії – поршневі та гвинтові компресори – з ряду причин не годяться для цього. Аналіз показує, що при сучасному стані компресоробудування неможливо створити відповідні для цього відцентрові турбокомпресори. Пояснюється це низькими густинами гелію та водню, високими швидкостями звуку в них, що призводить до малих ступенів їх стиснення в одному ступені турбокомпресора. У статті показано, що кількість ступенів стиснення можна істотно зменшити при переході до компримування сумішей водню та гелію з важкими низькотемпературними холодоагентами, наприклад, R12, R13, R14. Потрібно враховувати, що застосування холодоагентів у сумішах з воднем та гелієм призводить до зростання витрат потужності на стиснення у порівнянні з подібними процесами для чистих водню та гелію. Розглядаються два варіанти вирішення даної проблеми, які дозволяють роботу стиснення сумішей наблизити до роботи компримування чистих кріоагентів або навіть зробити її нижче. Один з варіантів заснований на організації стиснення кріоагенту в середовищі киплячого холодоагенту, а інший – на чергуванні процесів компримування та проміжного охолодження суміші киплячим холодоагентом. Крім того, для знаходження оптимальних проміжних параметрів суміші в установці отримано системи рівнянь, які можуть бути вирішені чисельними методами. Все це дає можливість розробляти високопродуктивні та ефективні КГУ та КВУ на основі машин динамічного принципу дії
