Authors: Dymchuk A. , Ponko L.
Published: November 2022

The article examines the influence of genotypic and phenotypic factors on the milk productivity of cows of the Ukrainian red-spotted dairy breed in the conditions of LLC "Agrofirma "Sonyashnyk" of the Globyn district of the Poltava region.

Based on the results of our own research, it was established that first-born cows of the studied lines differ in terms of milk productivity, which indicates the hereditary influence of genealogical formations. The highest indicators of milk productivity have animals of three lines - Marshal, Cadillac Rf and Cavalera Rf: Nadia - 7501.0-8775.9 kg, milk fat - 279.5-332.4 kg, milk protein - 234.9-271.4 kg Animals of the Eleveishna and Butmeike lines have the lowest indicators of milk productivity - 5065.2-5112.4 kg, 187.4-199.4 kg, 162.1-163.6 kg, respectively (P<0.05, P<0.01 , P<0.001).

The highest milk yield and milk fat are characterized by the daughters of the bulls Savva, Sapphire Et Red, V. Vilmos, Matrix Et Red and K. D. Lily Red Et - 8408.4-9007.0 kg and 319.5-347.3 kg, which on 772.5-3951.9 kg and 133.2-155.2 kg more than peers, respectively (P<0.05, P<0.01, P<0.001). The highest fat content is 4.0% in the daughters of Paradox Red Etn and Shchyglyk Et (P<0.05).

Our research proves that the live weight of firstborns at the first calving likely affects their milk productivity. With an increase in live weight up to 700 kg - their hope increases by 1545.3 kg, milk fat - 62.7 kg, protein - 53.5 kg (P<0.05).

According to the results of our research, it was established that the year of birth of first-born cows affects their hope. Thus, first-born animals born in 2018 probably exceeded animals born in 2012 in terms of milk yield by 2735.2 kg, milk fat - 90.2 kg, and protein - 87.7 kg (P<0.05, P<0.01, P <0.001).

It was established that indicators of milk productivity of first-born cows depend on genotypic factors by 10.1-24.5%. Paternal origin has the greatest influence, its influence on hope is 23.5 %, the content of fat and protein in milk is 15.2-24.5 % (P<0.05, P<0.01, P<0.001) . The second place is occupied by linear belonging, its influence on the above indicators is 20.7, 10.1-12.3 % (P<0.05, P<0.01).

The obtained data on the influence of phenotypic factors, including the year of birth, testify to the influence of the year factor on the milk productivity of first-borns. Quantitative signs depend on the conditions created for raising young animals or keeping first-born cows in a specific year of their birth. The strength of influence on hope, milk fat and protein content was 5.2, 15.1 and 5.7 % with high probability criteria (P<0.05, P<0.01, P<0.001).

The obtained results make it possible to develop comprehensive measures to increase the level of milk productivity of cows of the Ukrainian red-spotted dairy breed.
METHODOLOGICAL APPROACHES TO ASSESSING THE INNOVATION POTENTIAL OF THE ENTERPRISE
Authors: Yepifanova Iryna , Hladka Diana
Published: November 2022

The article is devoted to the study of theoretical and methodological approaches in determining the innovative potential of enterprises. The modern relevance of assessing the level of innovative enterprises is substantiated. The article examines the essence and provides a clear terminological definition of the concept of "innovation potential". The theoretical basis of the study is the scientific works of foreign and domestic economists regarding the problems of determining the level of innovation potential. The diversity of views of scientists is due to the significant number of types of innovative activity, the size of the scale, the resource intensity and effectiveness of the implementation of innovative solutions and projects, as well as the difference in the field in which innovations are implemented and the specialization of innovatively active enterprises. The work systematizes and summarizes the experience and analyzes the existing methods and approaches to the assessment of innovation potential. Their key characteristics are identified, the most widespread of them are highlighted, and examples of the calculation mechanism for a detailed assessment of the innovative potential of the enterprise are provided. In addition, a number of their advantages and disadvantages in modern methods and approaches are highlighted. The task of choosing the optimal method or approach for evaluating the innovative potential of an enterprise is difficult, taking into account the specifics of the enterprise's activity, its scale, the chosen industry, the size of enterprises, etc. Based on these synthesis results, an improved method of evaluating the innovative potential of the enterprise based on a comprehensive approach is proposed. It is proposed to evaluate the innovative potential of the enterprise based on the definition of its components in a certain sequence: innovative competences, innovative abilities, innovative resources and innovative projects.
LOGISTICS MODELS FOR EVALUATING THE EFFICIENCY OF GOODS MOVEMENT
Authors: Shvarts Iryna , Bezsmertna Oksana , Kraevska Alla
Published: November 2022

The article deals with an important applied problem of logistics management - evaluating the efficiency of goods movement. Given the importance of the problem of managing material flows at enterprises and constant changes in the conditions of the organization of supply chains, this topic is very relevant. In the conditions of the restructuring of many logistics supply chains, it is necessary to apply the following models for evaluating the movement of goods, which will take into account the most important criteria. In particular, a significant impact on the reconstruction of logistics chains and patterns of goods movement was made as a result of military operations in part of the territory of our country. Thus, the question arises of evaluating the effectiveness of new schemes of goods movement, taking into account new criteria. With this in mind, we included annual operating costs, annual transport costs, total capital investments, and the payback period of the project as part of the proposed distribution system selection model. The proposed model makes it possible to compare two distribution systems and choose the best one. The next task in the field of goods movement was the task of determining the coordinates of the distribution center, taking into account such parameters as the distance to the consumer and the traffic of distribution centers. The model for determining the coordinates of the distribution center proposed in the article makes it possible to take into account the changing factors of the external environment as much as possible and to choose the location of the distribution center that saves on transport costs, since the minimum distance and number of deliveries are ensured. The article also presented a graphic justification of the location of the distribution center.In order to maintain the appropriate level of quality of the logistics system of Ukrainian enterprises, the model for determining the level of logistics service was substantiated in the article. To assess the level of logistics service, we compared the time for logistics services that are actually provided by the firm with the time that would have to be spent on providing the entire set of possible services. All considered logistical tasks provide an opportunity to make effective management decisions regarding the organization of material flows at the enterprise.

Authors: Yepifanova Iryna , Dzhedzhula Viacheslav
Published: November 2022

Project management plays a key role in the activity of any business entity, as it ensures the coordination of necessary decisions regarding project goals, planning, and personnel. The process of project management has significantly developed with the growth of the IT industry, in which all companies have a project manager who is responsible for the timely and effective implementation of certain projects. At the same time, project management is important in all enterprises, since the activity of any enterprise can be considered as a continuous process of implementation of certain project decisions.

The purpose of the article is to systematize approaches to determining the essence and features of the project management process.

The implementation of the strategy involves the formation of a number of tactical tasks, which in their essence are certain projects of the enterprise. The work systematizes approaches to determining the essence of the project management process. It was determined that the process of project management is quite important in the process of forming the development strategy of all economic entities, as it affects the efficiency of operations, strategic development. Project management is the process of managing material, financial, and labor resources aimed at achieving a predetermined goal within the time frame set in the project. There are different approaches to the classification of projects, in particular by types, scales, complexity, sources of financing, terms of implementation, nature and scope of activity, status of participants, branch affiliation. The main differences between the projects and the current activities of the enterprise are considered.
Sédation profonde et continue jusqu’au décès : qu’en vivent les soignants ?
Authors: Peyrat-Apicella D. , Chemrouk Y.
Published: November 2022

Objectif : La récente loi Claeys-Leonetti de 2016 reconnaît le droit du patient à une sédation profonde et continue jusqu’au décès (SPCJD) si ce dernier en fait la demande. Au quotidien, comment les équipes soignantes s’approprient cette nouvelle possibilité et s’adaptent à ces situations de fin de vie spécifiques ?

Méthode : Nous avons mené des entretiens semi-directifs avec six soignants volontaires de chaque corps de métier (deux médecins, deux infirmier.ère.s et deux aides-soignantes) dans un service d’oncologie médicale et de radiothérapie. Les entretiens ont été analysés selon une méthode d’analyse de contenu thématique, afin de rendre compte du vécu des professionnels de soins face aux protocoles de SPCJD et aux conséquences sur les accompagnements de fin de vie dans ces circonstances.

Résultats : Cette enquête exploratoire met en évidence des disparités interprofessionnelles quant au vécu des accompagnements de patients sous SPCJD. L’hétérogénéité des représentations semble liée à une méconnaissance de la loi, à des acceptions variables, mais aussi à des intentions différentes en fonction des fonctions exercées. La continuité dans la prise en charge des patients est affectée : le seul point commun observé chez tous les professionnels concerne les difficultés décrites dans l’accompagnement des familles.

Conclusion : La loi Claeys-Leonetti, ayant pour objectif de donner davantage de droits aux patients, pose des enjeux éthiques et des difficultés aux soignants encore trop peu investigués à ce jour. Il semble fondamental de tenir compte de l’effet de cette procédure sur le vécu des professionnels, afin que la mise en place des protocoles soit accompagnée et pensée au mieux, dans le but de limiter les potentielles difficultés et souffrances relatives à la SPCJD.
Misdirection, Displacement and the Nisse in Hilda and the Black Hound
Authors: Earle Monalesia , Sanders Joe Sutliff
Published: November 2022

Luke Pearson’s comic for children, Hilda and the Black Hound (2017), introduces characters who live at the margins of society and who respond to those marginalising forces not with outright resistance but with what Monalesia Earle has called ‘misdirection’. As the characters move around and through the gutters of the comics page, they similarly slip between and around the authority that stands in their way. Literary theories related to formalism, children’s literature and the Gothic illuminate how the movement on the page hints at a form of disobedience.
Realizing the Dream of Teaching Girlhood Studies
Authors: Mitchell Claudia
Published: November 2022

A dream, dating back to 2001 when the late Jackie Kirk, Jacqui Reid-Wash, and I passed through a section labelled Girls Studies in Foyles Books on Charing Cross Rd., London, UK, was that someday there would not only be a journal devoted to girlhood studies but also a whole interdisciplinary teaching area. We talked about how students of youth studies, or childhood studies, or what was then called women’s studies might consider girlhood studies as an option in their programs or as a whole area of specialization. The dream of the journal was realized seven years later with the first issue of Girlhood Studies in 2008. Since then, as the guest editors of this Special Issue on Teaching Girlhood Studies highlight, there have been many initiatives including the development of courses on Girlhood Studies, and community/university activist projects. And now, finally, we have a whole issue devoted to teaching, curricula, and pedagogies of Girlhood Studies.

Authors: Ferdinand Renata
Published: November 2022

What is the relationship between Black Girlhood Studies and Black Motherhood Studies? In this article I answer this question by considering the ways in which these subjects can be explored together or in relation to each other. Using autoethnography, I describe the process of teaching Black Girlhood Studies with Black Motherhood Studies. Specifically, through narrative and performative writing, I draw upon my own personal experience of using research and scholarship associated with Black Girlhood Studies to inform and provide a foundation for the exploration of Black Motherhood Studies in an effort to promote a fuller, more complete and nuanced understanding of both social positions.
Gen Ed Girlhood
Authors: Almjeld Jen
Published: November 2022

While general education (gen ed) courses are commonly created as overviews of disciplines, a girlhood-centric approach celebrates a tightly focused introduction to girl identities as an entry point to critical analysis of gender and associated systems of oppression. I offer a rationale for my Cultural Constructions of Girlhood course and discuss specific assignments and strategies for introducing girlhood as a field of study for university students. This course offers grounding in how important childhood literature is in shaping our concepts of who we are and are allowed to be as well as indicating ways in which the idea of literature may be expanded and updated to include many modes and styles of text by attending to the artifacts of everyday girlhood.
Art School Grrls Hack the Girl Culture Final
Authors: de Jesús Melinda Luisa
Published: November 2022

Since 2008 I have had the pleasure of teaching Girl Culture at California College of the Arts (CCA), a private art/design college located in the San Francisco Bay Area. This article features student zines from Girl Culture at this college.

Girl Culture is part of the school’s general studies curriculum in the Humanities and Sciences at the upper division (junior and senior) level. The course title comes from Sherrie Inness’s foundational anthology defining American Girlhood Studies in the twentieth century, Delinquents and Debutantes (1998), in which she notes,

"Too often girls’ culture is shunted aside by scholars as less significant or less important than the study of adult women’s issues, but girls’ culture is what helps to create not just an individual woman but all women in our society. (11, emphasis in original)"

Girl Culture explores the myriad forces that have an impact on American girls’ lives today and seeks to identify the places where artists and designers can best advocate for girl-centric liberation, autonomy, and joy.

Evaluation of an Iranian ELT book series
Authors: Sedaghatgoftar Nasrin
Published: November 2022

Evaluating textbooks to ensure their efficacy and consistency with the course objectives is imperative as they are considered as pivotal components in English language teaching. The present study was an attempt to analyze and evaluate a local Iranian ELT book series taught at the adult department of Iran Language Institute (the ILI). In doing so, 60 English language teachers teaching English at the ILI for at least three years were invited to check their opinions on each item of the Nativized Checklist to Evaluate General English Course Books in Iran developed by Shatery and Azargoon (2012) who adapted and validated Joshua Mickley’s Checklist (2005) for the Iranian context. The design of the study was descriptive, and the data obtained were subjected to descriptive statistics to determine the frequency and percentage of the participants’ responses. The findings revealed that, generally speaking, the participants held a negative standpoint toward the content of the books. It was concluded the books need thorough modification and change. More elements of communicative language teaching need to be implemented and incorporated into the books and they need to get closer and closer to the real-world needs of the learners. Besides, more cultural elements should be provided to reinforce the learners’ cultural awareness and understanding of the target language. The findings have implications for materials developers, syllabus designers and language teachers.

Adaptive PID Fault-Tolerant Tracking Controller for Takagi-Sugeno Fuzzy Systems with Actuator Faults: Application to Single-Link Flexible Joint Robot
Authors: Elouni Mohamed , Hamdi Habib , Rabaoui Bouali , Braiek Naceur BenHadj
Published: November 2022

This paper considers the problem of Fault Tolerant Tracking Control (FTTC) strategy design for nonlinear systems using Takagi-Sugeno (T-S) fuzzy models with measurable premise variables affected by actuator faults subject to unknown bounded disturbances (UBD). Firstly, the Adaptive Fuzzy Observer (AFO) is proposed to estimate the faults. Based on the information provided by this observer, an active fault tolerant tracking controller described by an adaptive Proportional-Integral-Derivative (PID) structure has been developed to compensate for the actuator fault effects and to guarantee the trajectory tracking of desired outputs to the reference model despite the presence of actuator faults. The stability and the trajectory tracking performances of the proposed approach are analyzed based on the Lyapunov theory. Sufficient conditions can be obtained and solved for the design of the controller, and the observer gains using Linear Matrix Inequalities (LMIs). Finally, the effectiveness of the proposed technique is illustrated by using a single-link flexible joint robot.

Published: November 2022

This work presents an active control system applied to vibration level reduction in high-performance vertical transport, aiming at improving the passengers’ comfort in high-speed elevators. The control system design includes the use of a Proportional Integral Derivative (PID) control. Three strategies were proposed in order to achieve a 90% reduction in the vibration amplitudes: (I) the consecutive reduction of 90% of the displacements, (II) the consecutive reduction of 90% of the velocity, and (III) the consecutive reduction of 90% of the acceleration. The presentation of these three proposals allows their application for the use of different sensors. The performance of each strategy was evaluated through mathematical modeling and numerical simulations of a vertical transport with 4 degrees of freedom, submitted to excitations arising from rail deformations. Vibration and comfort levels in the cabin were numerically analyzed, taking into account ISO 2631 and BS 6841 standards for elevator lateral acceleration level and comfort level felt by passengers. Numerical simulations showed that the force required to reduce the vibration levels is practically the same for the three proposed strategies. However, strategy (III) – the successive reduction of 90% of acceleration – proved to be more efficient at improving passengers’ comfort level when compared to the other two strategies.

Acne is a skin disease that often occurs in adolescence and even adulthood, characterized by the presence of blackheads, papules, pustules, nodes, and cysts on the face, neck, upper arms, chest, and back. Although not life-threatening, acne can affect a person's quality of life by giving a bad psychological effect in the way a person assesses, perceives and responds to his condition and situation. The aim of this study is to asses the antibacterial activity of the extract and fraction of the macroalgae Euchema cottonii against acne-causing bacteria, namely Propionibacterium acnes and Staphylococcus epidermidis. The extraction method used was maceration, using 96% p.a ethanol as a solvent and fractionation using the ECC method with three solvents with different polarity levels, namely n-hexane, ethylacetate and ethanol. The activity test was carried out using the paper disc and micro dilution method with the comparison antibacterial clindamycin. The results showed that there was no antibacterial activity from either the extract or fraction of macroalgae Euchema cottonii against the bacteria Propionibacterium acnes, but there are activity from the extract and fraction (n-hexane and ethylacetate) against the Staphylococcus epidermidis bacteria with the MBC value at a concentration of 15% and MIC at a concentration of 5% (for the extract and n-hexane fraction), while for the ethylacetate fraction the MIC value was at a concentration of 10%. Therefor, the strength of the antibacterial activity of the extract and fraction of Eucheuma cottoni is in the weak category.

What's after the city? Perspectives on the rural-urban path of life
Authors: Pokrovsky Nikita
Published: November 2022

The article considers a wide range of general, theoretical, and practical issues related to the process of the centrifugal migration from the big cities to the so-called “small territories” (small towns and rural settlements). Is the urban form of settlement structure (especially megapolises) a timeless and entirely positive and non-alternative civilizational construction, stretching into an infinite perspective of the distant future, or does the modern city, filled with internal and external contradictions, constantly generates its antithesis in the form of reverse migration and the desire to live and work outside the urban environment? The cult of cities and urbanization, gradually formed in the early Modern History, has gradually generated and is currently generating a deep criticism of the phenomenon of urban life and, as a consequence, the process of de-urbanization. The article examines modern theories of de-urbanization (counterurbanization) and, on the basis of in-depth interviews, reconstructs various versions of the centrifugal motivations of “fugitives” migrants from the metropolis. These themes have become particularly important in recent years, marked by the total pandemic of COVID-19, which forced urbanitess to leave the cities in large numbers and settle in out-of-town space. The theme continues to resonate today, as the threat of an all-out military conflict, in the context of which the city becomes a particularly vulnerable target, has become evident.

The article explores the problem of memory and oblivion on the example of the tragic events of the 20th century associated with Auschwitz and the Gulag. The choice of this problem for analysis is due to its relevance by today, since in modern public life discussions about Stalin's repressions and the policy of Nazism haven’t lost their sharpness. Critical analysis and an unbiased assessment of these events today are faced with the phenomenon of “post-truth”, which generates a corresponding narrative, in which specific facts and analytical conclusions have less persuasive power than ready-made interpretations. The article discusses the question of how this issue fits into the global agenda as a whole, and whether it is particularly relevant for Russia due to its historical and cultural characteristics. Based on the works of modern philosophers, in particular, Valery Podoroga’s “Time after. Auschwitz and the Gulag: to think absolute evil”, an attempt is made to identify the main fractures of human subjectivity and the points of splitting of the individual. The destructive transformation of the human who has passed the test of a concentration camp manifests itself through the psychological state of the subject, the reflex work of the body, and as a result of bodily manipulations. However, Podoroga considers not exactly the survival in inhuman conditions, but continuation of life after the camp experience, as the main problem. If survival is a physiological overcoming; then life after survival is an existential struggle with the past so painfully experienced, which haunts and tries to constantly remind of itself. The evil of the past days has not been dissolved in the past, has not been fully comprehended either. The reasons for its origin have not been overcome and persist in the present. Until the tragic mistakes of the past are worked out, society will not find an incentive for moral development. The conducted research allows us to conclude that it is necessary to strive to recognize the Absolute Evil in various guises and prevent new humanitarian disasters, restoring memory and historical justice by realizing and experiencing guilt in one's own history, since memory is one of the main foundations of culture.
“If One Human Mind Has Come up with Something, Then Another Can Unravel It”. On the Centenary of the Birth of Yu.V. Knorozov
Authors: Albedil Margarita F.
Published: November 2022

The article deals with the scientific heritage of the great Russian scientist Yuri Valentinovich Knorozov (1922–1999). He is best known as the decipherer of the script of the ancient Maya Indians, who created one of the most distinctive civilizations of pre-Columbian America. This landmark discovery brought the scientist well-deserved glory and fame. Now his name is forever inscribed in the annals of domestic and world science. But the range of Knorozov's scientific interests and research was not limited to this topic. The scientist fearlessly took on difficult tasks, he believed that there were no unsolvable problems, it was only necessary to choose the right path of research. And he found such ways, relying on his encyclopedic knowledge, the intuition of a scientist and titanic efficiency. Knorozov studied different historical writing systems, which he considered as complex semiotic systems, perceiving them as a secondary code in relation to the language. Among them are the Proto-Indian script, the Easter Island script Kohau Rongo-Rongo, the Khitan script, the ancient Andean script, and the Ainu pictography. In his research, the scientist relied on the theoretical and methodological base he created in the process of deciphering the Mayan script. In fact, Knorozov built a general theory of decipherment, which is important for the study of any writing system. The scientist's interests also included theoretical problems, because the study of historical scripts was one of the particular tasks in the general problem of studying sign systems. This article discusses four areas of Yu.V. Knorozov's work: the decipherment of the Mayan script, the study of Proto-Indian texts, the Rapa Nui script Kohau Rongo-Rongo, and the Ainu pictography. The purpose of the article is to recreate some features of the multifaceted image of a ingenious scientist.

A scientific substantiation of solid-phase feedstock choice and preparation has been carried out, and the thermodynamic and kinetic aspects of solid-state hydride synthesis (SHS) of metal products have been analyzed using the nickel dichloride reduction as an example. The preliminary dehydration modes and methods for controlling the complete removal of crystalline water from chloride raw materials and Olenegorsk superconcentrate, which is natural oxide raw material, are described. Conditions, including initial solid chloride particle sizes, are established under which diffusion complications of reduction to metal in methyldichlorosilane vapor are minimized. Thermodynamic estimates of nickel chlorides and oxides reduction possibility, iron and copper with ammonia and methane at temperatures of 400-1000 K in equilibrium conditions have been carried out. It has been shown that the stoichiometric coefficients of the nickel dichloride in ammonia overall reduction reaction calculated by thermodynamic modeling are in agreement with experimental data. In contrast to the copper dichloride reduction, for nickel dichloride the formation of metal monochloride at the intermediate stage is uncharacteristic, which is associated with a higher thermal stability of nickel dichloride. The main kinetic regularities of the reduction of nickel, copper, and iron to metal under SHS conditions in ammonia, monosilane, and methane, as well as the nickel dichloride with methyldichlorosilane vapor and methane successive reduction, are considered. Approximation of experimental data by topochemical equations in a linear form showed that for reduction degrees a up to 0.7-0.8, these data are satisfactorily described by the Roginsky – Schultz equation. For a > 0,8 the “shrinking sphere” model works better, which confirms the localization of the solid-state reduction reaction at the interface, moves deep into the crystal with the formation of a of interlocked metal germs. The importance and prospects of the results obtained for the theory development of metallurgical processes, deep complex processing of natural iron oxide raw materials, metal products and new generation materials production, including superhydrophobic ones, are discussed. The relevance of the study from the point of view of applying the method of physical and chemical analysis to the study of complex heterogeneous metallurgical processes is noted.

Published: November 2022

To assess the possibility of selective disintegration and reduction of overgrinding of hard-to-reproduce ores, optical microscopic and X-ray microtomographic studies were carried out and quantitative characteristics of morphological parameters of disseminated and rich cuprous ore samples from Norilsk-type Oktyabrsky deposit were identified. Among quantitative morphological parameters the most informative are area, perimeter, edge roughness, sphericity, elongation and average grain spacing for disseminated copper-nickel ores; area, perimeter, edge roughness and elongation for rich cuprous ores. The studied parameters are characterized by increased values and dispersion in ore zones, which is especially important for fine-grained ores, which are difficult to diagnose by optical methods. Three-dimensional modelling of the internal structure of sulphide mineralisation samples was carried out using computed X-ray microtomography, which allows observation of quantitative parameters of grains, aggregates and their distribution in the total rock volume and interrelationship with each other. The evaluation of rock pore space by computer microtomography made it possible to compare the results obtained with the strength characteristics of rocks and ores, including those on different types of crushers. The obtained quantitative characteristics of structural-textural parameters and analysis of grain size distribution of ore minerals allow us to evaluate the possibility of applying selective crushing at various stages of ore preparation
