Development of software for calculation of optimal direction of solar panels during «time of use» in regions with complex topography
Authors: Gardashov Emin
Published: January 2023

The object of current research is efficient usage of solar energy via optimal panel orientation. Using the mathematical methods of finding extremal value of function, the software was developed to calculate the daily optimal direction of PV panel. The knowledge of daily optimal direction of PV panels enables to determine the optimal panel direction for any time of use which allows maximizing the amount of harvested solar energy. The proper functioning of this software has been confirmed by field measurements. It was found that panel optimal direction can be determined by considering only the direct solar radiation, since taking into account diffuse solar radiation of sky practically doesn’t affect optimal PV panel direction. The essential factors affecting the optimal direction of PV panel are the topography of the considered site and the significant changes of optical thickness, for example, before and after noon. The calculations also show that the partial cloudiness doesn’t remarkably affect the optimal PV panel direction, but the regular presence of clouds in same part of the sky does affect it. This software is applied to the Ukrainian site Verkhovyna for which the optimal daily, seasonal and annual solar panel directions are calculated and presented. The formula to calculate the optimal direction for any time of use via daily optimal tilt angle and daily direct solar radiation falling onto the panel is given. The interface of the software has been designed in a user-friendly way and can be easily used by wide range of consumers. This software will especially be useful for quick calculation of optimal direction of solar panels in tourist sites located in mountainous regions.

Published: January 2023

The article describes that budgerigar are the most widespread group of poultry. They are the 4th most popular pet in Ukraine after cats and dogs. Budgerigars are unpretentious, but they need a full and balanced diet and comfortable keeping conditions. The feasibility of using pelleted feed for a balanced and complete feeding of budgerigars is justified. It should make up at least 75% of the diet. It has been proven that pellets have a good effect on the parrot's body, because compressed feed contains much more nutrients, vitamins and microcomponents for the good development of the parrot's body. It is established that creation of a compound feed model with the help of recipe calculation optimization programs allows you to produce an effective compound feed. It allows to meet the needs of animals in nutrients and biologically active substances for life support, health, development, reproduction and obtaining high productivity. Recipe calculation programs permit you to choose components from the available raw materials, taking into account their quality, in the optimal ratio and the minimum cost of the finished product. As practice shows, the use of optimization programs of compound feed recipes allows you to reduce the cost of the product by 5 – 7%. It is proven that budgerigars should receive high-quality and balanced feed for normal development. The program complex for calculation and optimization of compound feed recipes "Korm Optima Expert" was used to develop recipes of pelleted compound feed for budgerigars with minimal cost. They meet the feeding standards and restrictions on the introduction of components and can be used for their complete feeding. Experimental samples of compound feed were made in accordance with the developed recipes of pelleted compound feed for budgerigars. Physical properties and chemical composition were studied in the experimental samples. It is established that the experimental samples are characterized by satisfactory physical properties and are balanced in content of nutrients and biologically active substances and meets the physiological needs and feeding standards of the budgerigars. The cost of raw materials for the developed pelleted feed is on average 10 UAH per 1 kg. It is advisable to produce pelleted feed for budgies, because the low cost and high quality will attract owners of budgies.

It was created in 1812 and had short stage run but was never printed. Text preserved in the National Museum Library of Warsaw is the earliest drama text of 19th century devoted to Bohdan Khmelnytskyi. The emerging of this text can be interpreted as the beginning of pre-romantic tendencies and rising interest in history of Ukrainian-Polish relations and Cossack epoch. At the same time, the play was as relevant as ever because there exists a strong desire of playwrights to respond to important social and political problems of that time.

The article reveals the specifics of artistic manifestation of the beauty concept based on V. Vynnychenko’s early works. This is due to the presence of a number of search lines in the writer’s interpretation of aesthetic and to a significant number of works representing current issues. Beauty is defined as a fundamental component of life in the works by V. Vynnychenko and several author’s plots of its comprehension are revealed. Firstly, it is found that in writer’s early works the characters experience a crisis of faith, emphasize the relativity of absolute truth and Christian ethics, rethink the concept of sin and sacred Christian commandments («Love your neighbour as yourself», «Do not deceive», «Do not kill», and «In the sweat of your brow, eat your bread»), professing dual moral standards and the idea of «benevolent selfishness». The writer places material values into the center of existence instead of spiritual Christian ones. The former acquire absolute status and most importantly are able to ensure the realization of the fundamental goal – to maintain vitality in the project of «fullness» of earthly existence. It is emphasized that in his early works, V. Vynnychenko substantiates the concept of «life-as-a-market», where you can get financial or moral compensation through «selling/buying/exchanging» valuables, among which female beauty is one of the fundamental values. The analysis confirms the idea that woman’s beauty and love are mercantilized due to the devaluation of spiritual values, they lose their ideal metaphysical essence and are transformed into ordinary goods and vital cycle of values components. That is closely connected with the problems of «exchange-purchase-sale» of the values, money cynicism and the interpretation of the family as an economic contract (the case of the story «The Poor People», dramas «Bazaar», «Young Blood», «Crucified»). In V. Vynnychenko’s art world, several search lines are connected with the category of beauty, particularly the problem of coordination of bodily, physically expressed female beauty with spiritual beauty in the context of «exchange of values». The author also experiments with the concept of free marriage, which is considered an alternative to an unhappy family as an economic project.

The article analyzes Kate Atkinson’s novels «Life after Life», «Ruins of God» and «Transcription» in terms of memory studies. The current objectives of the study were: 1) to outline private memories in the textual structure (these are the main correlates of individual and collective memory); 2) revealing the relationship between the injuries suffered by the heroes and the «wounds of time» inflicted by World War II; 3) understanding the mechanism of «crystallization» of collective memory in a particular cell («place of remembrance» in novels); 4) delineation of the boundaries of the cultural archive, which is reproduced by the author. The study found that the main message of the novels is focused on the theme of World War II, its understanding and reflection in the collective memory of the British. Through the images of the main characters, the author recreates the memories of wartime. It is noticed that in all novels the chaotic, instead of chronological principle of reproduction of the past is applied: the plot acquires cyclic character. This image principle mimics the work of the human brain, which sporadically emits layers of memory. This kaleidoscope of memories follows the author’s logic: the scattered fragments of memory form a coherent history, correlated with the national archive. Teddy Todd is a survivor who survived to preserve the memory of his fallen comrades («places of remembrance») and to testify about war crimes, as well as to nurture a new generation of Britons. At the same time, Ursula Todd and Juliet Armstrong present a feminine but polar experience of war. At first glance, there are no significant differences between the heroines: both work for secret military departments, contributing to the approach of victory, both took the place of men who went to the front. At the same time, Juliet Armstrong is a double agent recruited for espionage in favor of the Soviet Union, who, through her own betrayal, separates herself from the collective memory. Miss Armstrong’s memoirs do not correlate with the National Archives, but are the antithesis of the British collective consciousness, constituting an unexplored «white spot» (the phenomenon of betrayal is indeed something of a native «stain»). The post-war duty of Teddy and Ursula Todd, the true heirs of national values, is to heal the «place of remembrance» and to preserve the memory of the fallen. Todd’s memories should be embodied in «places of remembrance» (monuments, museums, military burials, works of art, etc.). The conditional archive of the novel, the «place of remembrance» recreated in it, correlate with the collective memory of the peoples of Britain, thus encouraging the understanding of the traumatic experience of World War II.
MEANS OF REPRODUCING THE INDIVIDUAL PAST IN W. SEBALD’S NOVEL AUSTERLITZ
Authors:   Institute of Philology of Taras Shevchenko National University of Kyiv, Megela Ivan
Published: January 2023

The article is devoted to the coverage of the problem of bricolage as a method of memory reconstruction in the novel “Austerlitz” by the greatest German writer Winfried Sebald. The article notes that “Austerlitz” marks the transition from trauma to conscious identity as part of the historical memory of the Holocaust. It shows how the hero of the work, Jacques Austerlitz, acquires his identity by assembling from scattered information his personal history, reflecting a significant part of the collective tragedy. The genre feature of the work as a travelogue, memoir, investigation, as literature bordering on documentary and artistic experience, where the real is combined with the fictional, is highlighted. The article describes in detail the content of the technique of bricolage as a form of “wild”, “pre-rational” way of thinking, as a technique of fitting auxiliary materials (old photographs, newspaper clippings), a montage of disparate episodes, the technique of collage. The structure of the work’s storytelling is analyzed when the narrator does not tell the story but describes what he hears from Jacques Austerlitz. It is as if it is not a text, but the story itself, which someone tells, and also shows pictures for authenticity. The functions of the hero in the novel gradually shift from people to things, documents, bearers of the memory of individual and collective civilizational catastrophe. These indescribable witnesses break the blockade of traumatic silence around the childhood of Austerlitz, embodied in images of blindness, dumbness, oblivion. Before the protagonist of the work, the “man without a past,” the history of his family, the ghostly happy childhood that was rudely cut short by the separation from his biological parents, is suddenly revealed. Sebald demonstrates a contemporary form of novel narrative in which the truthfulness of the Holocaust narrative is revealed by incorporating the exile’s personal authorial biography, pain, and guilt into the memory of this tragedy. The role of photographs and descriptions of architectural structures in revealing the immanent semantic content of the subject, not manifested verbally, is analyzed. The latter is the key document that unites and structures the important for the writer themes of memories, memory, indifference, oblivion, return to the ghostly past, overcoming of the psychological trauma. Based on the analysis the author concludes that the attitude to the reader as a co-author brings Sebald’s novel closer to the tradition of the European intellectual novel and postmodern hypertexts, in which meaningful units are not presented in a traditional linear sequence, but as a multiplicity of links and transitions. The author notes that the acute experience of humanitarian catastrophe, the multilayered text, the density of meaningful meanings make this work a notable phenomenon in the context of artistic comprehension of traumatic memory.
THE DISCOURSE OF TOURISM: AN ANALYSIS OF THE ONLINE ARTICLE “10 BEST PLACES TO VISIT IN UKRAINE”
Authors:   Kyiv National University of Trade and Economics, Pryma Viktoriia
Published: January 2023

The article shows the fact that the concept of scientific discourse is interpreted as a complex phenomenon that consists of participants in communication, communication situations and the text itself. The conclusion is that discourse is an abstract invariant description of structural and semantic features that are realized in specific texts. Linguists interpret the concept of discourse as a complex communicative phenomenon that includes the speaker and the addressee of the message, the process of proper formation of speech, extralingual factors of communication, social and cultural background. This article presents a critical reading of the text “10 Best places to visit in Ukraine” and its overlook, research study in the field of online tourism promotion, published online in 2021 by one of the world’s largest tourism publishing houses, Touropia. The study aims at revising some of the characteristics of the ongoing tourism discourse through an analysis of the network of people and practices involved in these publications, their textual features and images. The article analyses the way in which various modes to create a virtual brochure with a promotional message from both institutional and commercial positions were combined. In doing this, it studies the organization of the website and its webpage, as well as the lexico-grammatical and visual features of its promotional messages. The analytical framework used includes critical discourse analysis and a corpus-based tool used to interpret different aspects of this tourism discourse. The places advertised as “Top 10” are presented to an all-aged audience that must be interested in discovering new places, appreciated to nature, fond of history and ready to consume national products. Polyparadigmatic nature has led to the active use of these terms in the field of literature, as a result of which scientific studies address issues of artistic concept, artistic discourse, which will always be open to researchers, while not exhausting its relevance.

The article reveals the relevance of the study and defines its purpose. The experience of domestic and foreign scientists is highlighted, which allowed us to say that this issue is insufficiently studied. It is emphasized that the problem of studying existential certainty in student age needs special attention, because the problem of the meaning of life and its place in the world is the core that ensures the harmonious development of the learner. Accordingly, a theoretical overview of the problem of the meaning of life, the way of life of man, which involves the achievement of personal authenticity, ie the holistic realization of the individual, which is manifested in his mentality. The concepts of «existential certainty», «subjective well-being», «emotional intelligence» are revealed. A set of research methods is determined. It is established that the existential certainty on almost all scales of existentiality has average indicators, the scale «Self-transcendence» has high indicators. It is proved that the majority of respondents showed medium and low EQ results. It was found that the subjective well-being of respondents varies from high to medium. Correlation analysis of the results of the study concluded that the higher the level of existential certainty, the higher the level of emotional intelligence and subjective well-being, ie there is a direct interdependence. According to the results of the study, practical recommendations for the formation of relevant competencies and emphasis on the development of emotional intelligence of students, including exercises and tasks to improve emotional intelligence and acquire practical skills to identify emotions and skills of affective regulation. Also, art-therapeutic means of development are offered, the use of which allows to master the skills of mental self-regulation, which affects not only the increase of emotional intelligence, but also existentialism and subjective well-being. It is concluded that there is a direct relationship between existential certainty, emotional intelligence and subjective well-being, which suggests that existential certainty affects the formation of the worldview of students of pedagogical ZVO. The study of existential certainty in a crisis is seen as a research perspective.

Published: January 2023

Modeling the image of a teacher of higher education is an integral part of the development of modern pedagogical imageology, which is being formed as an interdisciplinary direction. In our study, we analyzed the modern scientific experience devoted to the study of the image of a teacher of higher education. This made it possible to determine the current state of the views of researchers who worked in this direction. The purpose of the article is to highlight the results of research on the content and structure of the image of a teacher of higher education. Summarizing the views of different authors, we formed a general idea of the content of the category of the image of a teacher of higher education, identified the components of the image of a teacher of higher education, identified general characteristics of the image of a teacher of higher education from different positions, components of the image of a teacher of higher education. This allowed us to define the category of the image of a teacher of higher education and to propose an author’s model of systematic description of the image of a teacher of higher education, which is an attempt to find a connection between the components of the image of a teacher of higher education and the environment in which this image is formed. The general components of this model include: determination of the image of a teacher of higher education (sociopsychological aspect, acmeological aspect, activity aspect); bearer of the image of a teacher of higher education; the context of interaction between the bearer of the image and the recipient of the image of a teacher of higher education; symbolic space formed by the bearer of the image of a teacher of higher education; nature of interaction (subject-subject interaction / subject-object interaction); process, forms, types, means of communication; recipient of the image of a teacher of higher education determination of obtaining and accepting the image of a teacher of higher education (activity aspect, acmeological aspect, socio-psychological aspect). Author’s definitions of these categories are given.
Doctoral Education in Post-Soviet Countries: From a Unified Model to Variety of Approaches
Authors: Sotnikova M. I.
Published: January 2023

The article analyses the institutional landscape of doctoral education in the Soviet Union in the last years of its existence as well as in the countries of the post-Soviet space. We describe the practice of academic personnel training in the post-Soviet countries, highlighting the general characteristics determined by the Soviet legacy, along with the unique patterns of the countries. The empirical base of the study is formed by the Soviet Union archival statistical data, legal acts, and data of the statistical services, ministries, and departments of the post-Soviet countries. Statistical analysis is used to assess the institutional structure and scale of the postgraduate schools in the considered countries. The research reveals that most of the post-Soviet countries have preserved the features of the Soviet postgraduate school, while very few countries have created models of institutional structure with a fundamentally different configuration of doctoral education in comparison with the Soviet Union.
Disproportions of Supply and Demand in the Personnel Reproduction System for the Transport Industry
Authors: Vinichenko V. A.
Published: January 2023

The modern system of personnel training for the transport industry has undergone significant changes after the collapse of the mechanism of graduates’ distribution and the transition to a three-level model of training in higher education. The permanent crisis in the educational environment has led to the emergence of supply and demand imbalances. The article analyzes the needs of the transport industry in the context of each segment (automobile, railway, water, air) and assesses the capabilities of the personnel training system for working in transport. The universities’ subordination has influenced the percentage of specialization of each of them and the share of students at the expense of budget allocations. The determination of the coefficients of paired regression shows a direct and quite a strong connection between the indicated parameters. The market capacity of the transport industry is assessed, showing that currently there are employees of aviation enterprises in excess. The other sectors are more or less deficient. The cohort-component method forecasts an even greater demographic deficit in the long term. There are generalized the results of personnel training by universities subordinate to the Ministry of Transport of the Russian Federation, as well as some quantitative parameters of the needs of transport enterprises.

This research is an attempt to explain the imbalance between the demands of the transport industry and the capabilities of the higher education system. What seems practically important is that the study specifies the emerging disproportion in the context of individual sectors of the transport industry. This approach will probably allow the reader to make system management decisions for coordinating the educational process participants’ actions.

Authors: İSLAM Ali , ORTA Hale , AKA KAÇAR Yıldız , DÖNMEZ Dicle
Published: January 2023

Cherry laurel (Laurocerasus officinalis) belongs to the Rosacea family. The main distribution area for edible cherry laurels is the Blacksea shores in Turkey. In the study, it was aimed to reveal the differences among the various cherry laurel genotypes by using the SSR molecular marker technique. Cherry laurel genotypes were selected from the Black Sea Region of Turkey. A total of 15 SSR primer pairs were developed and used for Prunus species, and the phylogenetic relationship and polymorphism rates were also demonstrated. As a result, 13 SSR primers resulted in scorable DNA band profiles. UDAp-401 SSR primer was detected with a minimum of 3 alleles and BBCT001 primer with a maximum of 17 alleles. The average number of alleles was observed at 9 per locus. Whereas, the average number of polymorphic bands per SSR marker was calculated as 8.38. Additionally, 109 polymorphic DNA profiles were obtained from a total of 117, and the polymorphism rate was calculated as 93.5%. The band patterns resulting from SSR analysis showed multiple alleles, suggesting polyploidy in cherry laurel. In conclusion, we determined that the SSR molecular markers could be used to identify the different cherry laurel genotypes. Furthermore, these results depicted that among the different genotypes sampled there is significant genetic variability that can be useful for future research and breeding programs.
Do Agricultural Supports Affect Production? A Panel ARDL Analysis of Turkey
Authors: BULUT Erdem , BAYRAKTAR Yüksel
Published: January 2023

One of the controversial issues in the trade negotiations carried out with the World Trade Organization deals with agricultural supports related to production, which is claimed to disrupt the market system by creating an imbalance in supply and demand in the domestic market and to cause world trade contraction. In this context, the aim of this study is to examine the production effect of the deficiency payments and land-based direct supports widely used in Turkey. The study conducts a panel autoregressive distributed lag analysis for 11 selected agricultural products (wheat, corn, sunflower, seed cotton, paddy, soybean, canola, safflower, tea, dried beans, and olives) for the 2002-2019 period. The findings from the study are as follows: i) Increases in deficiency payments and land-based direct supports increase short and long run production. However, land-based direct supports have less of an effect on production. ii) While increases in input prices have a negative short run effect on production, the long run effect is the opposite. iii) Agricultural product price is not an important indicator for producers. This finding can be explained by the fact that farmers accept agricultural supports as a complement to the price variable in their production decisions. iv) Increases in the minimum wage added to the model based on Turkey’s structural characteristics have a negative long run impact on production. v) No statistically significant relationship exists between the number of tractors used to represent agricultural mechanization and the amount of production.

Published: January 2023

Background: Stroke is the second most common cause of death globally and the third most common cause of disability. The prevalence of stroke is increasing despite managing various stroke risk factors that have improved considerably. Ischemic stroke is the most prevalent type, and about 90% of stroke events are attributable to modifiable risk factors. This study aimed to explore the characteristics and risk factors of patients with acute ischemic stroke in Dr. Hasan Sadikin General Hospital.Methods: A descriptive cross-sectional study was conducted retrospectively in October 2020, using a total sampling method on medical records of acute ischemic stroke patients in Dr. Hasan Sadikin General Hospital year 2019. Medical records with incomplete and missing data were excluded. Demographic and known risk factors data were collected and presented in the table.Results: Of the 355 subjects, male patients (n=69, 76.7%) were predominant, with the age range of 55–64 years old (36.1%). The majority of the subjects had an ischemic stroke of large-artery atherosclerosis (68.2%) with carotid system involvement (93.2%). As much as 305 subjects (85.9%) had hypertension as the risk factor, followed by dyslipidemia (47.3%), heart disease (39.4%), previous stroke history (33.8%), smoking (25.6%), diabetes mellitus (24.5%), hyperuricemia (12.1%), and blood disorders (2.3%).Conclusions: Males in the older age group have a higher risk of getting acute ischemic stroke with ischemic stroke of large-artery atherosclerosis and carotid system involvement, and hypertension has the highest prevalence.
The myth of meritocracy: academicism and methodological flaws in Brazilian public recruitment
Authors: Oliveira Antonio Batista da Silva , Castro Junior Joel de Lima Pereira , Montalvão Sergio de Sousa
Published: January 2023

Abstract Is there meritocracy when 58% of administrative assistants and 87% of physicians employed in Brazilian federal higher education institutions (HEI) were selected through public exams based solely on theoretical multiple-choice tests? Is there meritocracy in selection processes that do not assess the candidates’ experience or apply discursive or practical exams? This article addresses a historically constructed assumption assimilated as a kind of myth in Brazil: the idea that the current model for filling government positions is meritocratic. The extreme objectivity of these public exams reduces the Brazilian tradition of nepotism but presents serious flaws. One is academicism, which overvalues educational titles and theoretical knowledge at the expense of essential skills for many government positions. Calls for civil service entrance exams to fill administrative and medical positions in federal HEI throughout Brazil were verified using the descriptive statistics method (via frequency analysis), tabulating the evaluation types used in each selection, and generating tables and graphs. The results suggest adopting assessments more broadly connected with the competencies the positions require and prioritizing skills and practical behaviors instead of theoretical knowledge of little or no applicability. The study points out alternatives for a nation with more than 200 million inhabitants, the vast majority of which do not realize the incalculable damage of real academicism and illusory meritocracy.
Neoliberalismo e envelhecimento ativo: O papel dos programas empresariais de preparação para aposentadoria
Authors: Bernardinelli Ingrid , Candido Silvio E. A. , Tonelli Maria J.
Published: January 2023

RESUMO Objetivo: Analisar a relação entre a ascensão dos programas de preparação para a aposentadoria (PPA) e as transformações no ambiente ideológico das organizações associadas ao advento do espírito do capitalismo neoliberal. Originalidade/valor: Poucos estudos da literatura brasileira abordaram a difusão dos PPA a partir de perspectivas críticas e, em especial, no ambiente empresarial. A maioria das pesquisas abordou instituições públicas. Em relação à literatura internacional, o texto inova ao associar a ascensão da ideia de envelhecimento ativo à tese do novo espírito do capitalismo, desenvolvida por Luc Boltanski e Ève Chiapello. Diferentemente dos estudos internacionais existentes, a análise enfoca os PPA como instrumentos de difusão da ordem dominante na esfera organizacional. Design/metodologia/abordagem: Para a consecução dos objetivos propostos, uma pesquisa qualitativa foi realizada. Obtiveram-se os dados com nove informantes de cinco consultorias que atuam na estruturação de PPA empresariais e com duas empresas que estruturaram seus programas recentemente. Foi realizada uma análise de conteúdo temática. Resultados: Os resultados revelam que os PPA elaborados promovem concepções de envelhecimento ativo consoantes com o novo espírito do capitalismo e com as alterações nas formas de organização do trabalho impulsionadas pelo neoliberalismo, o que possibilitou conceituar os PPA como um objeto que incorpora e facilita a difusão do envelhecimento ativo e a construção de uma aposentadoria em atividade. O estudo avança na compreensão das implicações dos novos discursos sobre a velhice para as organizações e estimula uma compreensão mais crítica dos PPA nas organizações públicas e privadas.
Trajetórias familiares na pecuária leiteira no sul do Brasil: entre a especialização e o fim da atividade
Authors: Thies Vanderlei Franck , Schneider Evandro Pedro , Matte Alessandra
Published: January 2023

Resumo: O presente estudo pretende contribuir na identificação e explicação das mudanças nos sistemas produtivos de agricultores familiares produtores de leite bovino no Sul do Brasil. Foi realizada pesquisa de caráter histórico e comparativo, por meio de análise longitudinal das trajetórias de agricultores familiares, utilizando como contexto empírico a realidade de 58 famílias, em 2003 e 2018, pertencentes ao município de Salvador das Missões, no estado do Rio Grande do Sul, Brasil. Os resultados destacam a tendência histórica de especialização, ganhos de escala e concentração produtiva na pecuária leiteira, em paralelo com o processo de descontinuidade na produção e venda de leite por parte expressiva das famílias pesquisadas. O estudo longitudinal permitiu identificar: movimento majoritário de migração das famílias da produção comercial em direção à categoria sem produção de leite; movimento fragmentário de famílias da categoria de autoconsumo para a categoria de produtores comerciais; e inexistência de famílias que passaram de não produtoras para produtoras de leite. A descontinuidade da produção esteve associada a famílias menores, com maior idade média dos seus integrantes, sem sucessores e frágil apoio das políticas públicas.
Influence of particle size of aggregates on the rheological behavior of crowded suspensions with silicone oils with different viscosities
Authors: Mendes Thiago Melanda , Pillegi Rafael Giulian
Published: January 2023

ABSTRACT Two different sizes of aggregates of glass microspheres were compared in suspension with silicone oils of different viscosities. The concentration of the suspension was kept constant and equal to 62 vv.%. The rheological behavior of the suspensions was evaluated by the squeeze flow test, for two test speeds. For both particles size, when immersed in less viscous silicone oil, the yield stress did not show a good correlation with the tests speeds. Meanwhile, the more viscous silicone oil led to a good correlation between the yield stress and tests speeds. For the finer granulometry, the “viscosity” of suspensions increases with increasing viscosity of silicone oils and test speeds. But for the coarser granulometry, the “viscosity” of suspensions increases with the test speeds, and decreases as the viscosity of the silicone oils increases. These differences in the rheological behavior are closely related to the occurrence of non-homogenous flow, which depends on the relation between the percolation speed of silicone oils and the test speeds of the squeeze flow test. Thus, the size of particles influences in different ways the rheological behavior of these suspensions of glass microspheres. Consequently, a combination of the matrix phase viscosity and granulometry of aggregates phase can lead to a homogeneous flow.

Bearing capacity tests were carried out on axially and eccentrically loaded coral concrete short columns reinforced with carbon-fibre-reinforced polymer (CFRP) bars. Parameters such as the ultimate bearing capacities and the stress in the CFRP bars and surface concrete were measured and analysed. All the columns failed due to the crushing of concrete in the compression zone. An increase in eccentricity not only decreased the ultimate bearing capacity, but also resulted in the shear fracture of CFRP longitudinal bars in the compression zone. In general, the stress of the longitudinal CFRP reinforcements in all specimens was quite low. The maximum stress of the CFRP bars in the columns was 105.78 MPa, just 23.5% of the ultimate compressive strength of the CFRP reinforcement. The superior bond between the CFRP bars and coral concrete conformed to the deformation coordination. A calculation method for the bearing capacity of CFRP-reinforced coral concrete short columns was developed and the calculated results were found to agree well with the test results.

The German Work Role Functioning Questionnaire – on the evaluation of its measurement properties Objectives: Measures to maintain the employability of workers should also take their functional ability into account. The Work Role Functioning Questionnaire (WRFQ), which is available in several languages, is suitable for such an assessment. A validated version in German had been missing until now. The 27-item questionnaire was culturally adapted from the Dutch version of WRFQ 2.0 and used with a heterogeneous sample of employees with the aim of psychometrically validating the overall scale and the four subscales. Methods: After adaptation, members of a commercial online access panel with a wide variety of occupations were recruited (T0: n = 653). Two follow-ups were conducted to assess further psychometric properties (T1: n = 66, T2: n = 95). We examined the 1) structural, 2) convergent and 3) discriminant validity using exploratory factor analysis, 4) floor and ceiling effects, as well as 5) the internal consistency, 6) reproducibility, and 7) responsiveness. Results: Measurement properties were found to be good, with the exception of responsiveness and structural validity. In the exploratory factor analysis, satisfactory replicability was found for three of the four subscales (mental and social demands, physical demands and flexibility demands, but not scheduling and output demands). Conclusions: The WRFQ is aimed at the fit between demands and the individual and thus at the ability to participate. With the development and validation of a German-language version, the scale can be used in practice, e.g. in interventions aimed at secondary prevention to maintain the ability to work, tertiary prevention to support a successful return to work, or the identification of employees with declining functional ability. The limitations of the study (limited representativeness of online access panels and poor replicability of the fourth subscale) require further research.

Direct conversion of wind energy into heat is a relevant direction for the development of alternative heat power engineering. The paper considers an efficient wind heat generator that consists of two rotors nested in each other's annular gaps and forming a system of cylindrical coaxial annular channels filled with a viscous working fluid. Depending on the properties of the working fluid, the velocity of the rotors, the number of annular channels and their geometry, there are combinations of parameters for the optimal design of the heat generator. The proposed method for selecting the design parameters of coaxial rotors makes it possible to directly select the optimal design of rotors for a given power of the heat generator and the properties of a viscous working fluid. The design of the multi-cylinder system of the heat generator, which uses the annular Couette–Taylor flow, is presented in the form of an equivalent single annular gap, which made it possible to generalize the results of investigations carried out with different working fluids under various conditions, in the form of a single dependence of the dimensionless power of the heat generator on the number Reynolds. The obtained dependence is well approximated by a linear function in the experimentally studied range of Reynolds numbers. An algorithm for calculating the geometric design parameters of a multi-cylinder annular system is proposed. As an example, calculations of the structural dimensions of nine variants of heat generators for three power values are given: 10 kW, 20 kW and 50 kW.

In view of the continuous growth of global energy consumption, reduction of non-renewable energy sources, as well as increasing greenhouse gas emissions, it is necessary to introduce pro-mising methods to increase the importance of rational use of energy resources in the industrial, domestic and scientific and technical fields, which will reduce the amount of energy to provide the same level of energy supply of buildings or technological processes in production. This paper considers superhydrophilic capillary-porous surfaces capable of providing heat exchange through phase transition, which is of fundamental importance in evaporative radiators for space applications, heat pipes, as well as in the operation of cooling towers for electricity and heat production in centralized heat supply systems. The study of the heat exchange process with phase transition on the capillary-porous surface was carried out by conducting experiments on evaporation of water-ethanol mixture of different concentration under conditions of forced convection at diffe¬rent orientation of the modified surface in space. The results obtained in this work allow us to judge about the effectiveness of capillary-porous structures in heat exchangers operating on eva¬poration cycles and the Maisotsenko cycle, and are also applicable to further study of heat and mass transfer processes occurring on superhydrophilic capillary-porous surfaces.
