Introduction. High prevalence of early pregnancy loss regardless of methods of conception still remains a relevant problem. One of the ways to identify the etiology of pregnancy loss is a histological examination of the products of conception (POC), decidualization in particular, which often remains underestimated in clinical practice. The aim of the study was to evaluate the decidualization of the endometrium in the retained POC after IVF. Materials and methods.Histological and immunohistochemical analysis of decidualized endometrium was carried out on 153 samples of retained POC around 5–8 weeks of gestation after IVF and on 15 samples of POC after artificial abortion. The POC was fixed in a 10% neutral formaldehyde solution, and a standard histological examination was performed. The immunohistochemical study was carried out to evaluate the expression of estrogen and progesterone receptors in the endometrial glands and stromal cells of the decidualized endometrium compact layer. Results. We verified 5 types of decidual endometrial stromal and glandular transformation of a missed abor-tion material after IVF. The morphological features of decidaulized endometrium in missed abortion after IVF are characterized by a complete and impaired stromal transformation with various types of glandular transformation and disynchronous expression of estrogen and progesterone receptors. Conclusion.We described the morphological variants of the decidual endometrial transformation in POC after IVF, which serve a new direction to the understanding of endometrial factor as one of the main determinants of recurrent implantation and reproductive failure often remaining out of the specialist’s focus. Keywords: missed abortion, complete and incomplete gravidar transformation of the endometrium, estrogen and progesterone receptors, IVF

Introduction. Chordomas are rare malignant neoplasms that are highly recurrent and with limited treatment options. Invasion of the vital structures of the nervous system complicates their treatment. The search for new methods of drug therapy for chordomas is an urgent problem. The aim of the research was to study PD-L1 expression in tumor cells and tumor infiltrating lymphocytes (TILs) in chordoma samples and its interrelation with tumor characteristics and prognosis. Materials and methods. We analyzed PD-L1 expression in 30 primary chordomas using immunohistochemistry and differences in independent groups using Chi-square and Kruskal–Wallis tests. Survival analysis was performed by constructing Kaplan–Meier survival curves. We compared the significance of differences with the logarithmic rank test. Differences were considered significant at p<0.05. Results. PD-L1 expression was detected in tumor cells in 43% of samples and in TILs in 80%. PD-L1 expres-sion in tumor cells and TILs was not associated with the clinical features of the disease. However, PD-L1 expression in tumor cells in all samples correlates positively with the content of this marker in TILs (r=0.409, p=0.028). Different histological variants of chordomas were shown to differ in the content of PD-L1 in both tumor cells and TILs. PD-L1 expression in tumor cells is not a predictor of the disease, while its expression in TILs tends to be a marker of a favorable prognosis (HR=0.1429; p=0.0570). Conclusion. We found the lowest level of PD-L1 expression in both tumor cells and TILs in dedifferentiated chordoma. PD-L1 expression in TILs is associated with a favorable prognosis of chordomas and indicates the potential for the use of checkpoint inhibitors in therapy. Keywords: chordoma, PD-L1, lymphocytes, prognosis, survival

Introduction. Alcohol abuse is one of major health and social problems of modern society, the essence of which is an increase in morbidity and mortality not only from alcohol misuse and its complications, but also from associated comorbid pathologies. The liver is the organ that is affected most by ethanol and its metabolites. A significant factor leading to melatonin-associated morphological manifestations in the liver is the so-called light pollution, a violation of the light–dark regime. At the same time, heavy consumption of alcohol over a short period of time (alcoholic excesses) and other forms of alcoholic illness are often associated with various sleep disorders. The aim of the study was to investigate the morphological and functional state of the liver of Wistar rats under experimental alcohol intoxication in conditions of a fixed light regime and constant illumination. Materials and methods. Male rats (n=160) were kept under a fixed light regime, constant illumination, and at a combination of both light regimes with simultaneous experimental alcohol intoxication. We performed a pathological examination of the liver and determined morphometric parameters, hepatocyte ploidy, and the proportion of binuclear hepatocytes. Results. The consumption of 15% ethanol solution as a drink ad libitum for 3 weeks at a fixed light regime causes the development of fatty degeneration in the liver of laboratory animals. Secondary to it, changing lighting from fixed to constant is accompanied by the development of alcoholic hepatitis in about half of the animals. The results of micromorphometry indicate significant changes in the studied parameters of hepatocytes, which are expressed least of all in the case of ethanol consumption under fixed lighting condi-tions and affect most the cells of the liver parenchyma of rats with chronic alcohol intoxication secondary to constant lighting. Conclusion. Alcohol intoxication that occurs secondary to a melatonin deficiency caused by constant lighting is accompanied by a much greater severity, prevalence, and intensity of inflammatory tissue reactions and a variety of manifestations of liver pathology. Keywords: hepatocyte, alcohol, lighting regime, stress, fatty degeneration

Thin plates with arbitrary shapes and stiffeners find wide usage in construction, aerospace, marine, etc. industries. In the present work a parametric investigation of thin structural steel plates has been carried out. The design parameters considered were the subtended angle and aspect ratio of plates to account for the different shapes of plates used for various applications. Another design parameter that was considered is the stiffener and its different orientation. The impact of varying parameters on the first five modal frequencies and in turn the stiffness was considered as the response. Finite element method (FEM) coupled with Taguchi’s L16 orthogonal array and grey relational analysis was used to maximize the first five natural frequencies simultaneously. The thin plate was subjected to modal analysis when all its sides are in simply supported boundary condition. The optimum combination of design variables predicted by grey relational analysis is a thin plate with 80° subtended angle, 1.75:1 aspect ratio and crossed stiffener orientation for simultaneous maximization of the frequencies. Analysis of variance revealed highest contribution of stiffener type which affects the first 5 natural frequencies simultaneously.
Sympiesis notata (Hymenoptera: Chalcidoidea: Eulophidae), a gregarious parasitoid of Hesperiidae (Lepidoptera), and some records of other Chalcidoidea associated with skipper butterflies in the Western Palaearctic

Published: January 2022

Sympiesis notata is a gregarious ectoparasitoid of skipper butterfly caterpillars. Other Lepidoptera larvae in leaf mines and leaf folds are attacked by the same morphospecies, but on these smaller hosts S. notata is usually a solitary parasitoid. Other Chalcidoidea
recorded as reared from hesperiid hosts are mostly species of Brachymeria (Chalcididae) and Elasmus (Eulophidae), which are primary parasitoids, and Catolaccus (Pteromalidae) which are pseudohyperparasitoids attacking cocooned ichneumonoid primary parasitoids. Species
of Pteromalus, Baryscapus and Tetrastichus are also reported as secondary parasitoids from hesperiid hosts.

Authors: Alabbad Yazeed , Demir Ibrahim
Published: January 2022

Flooding is one of the most common natural disasters affecting communities worldwide. It is expected to persist with increasing magnitude and frequency as a result of climate change, resulting in both direct and indirect negative consequences. The flood impact assessment is considered as a key component of flood risk management strategies, such as benefit-cost analysis for mitigation planning. This study aims to provide a comprehensive assessment of socio-economic impacts for the 100 and 500-year flood scenarios for major Iowa communities. The analysis includes impact on essential facilities, businesses, and vehicles, loss of life, amount of debris transported downstream, displaced population, and floodplain vulnerability classification. Due to the differences in the topography and the spatial distribution of buildings and infrastructure, and the absence of sufficient flood prevention measures within the study area, our findings illustrate that some communities will suffer significant damage and losses during flooding. This research could aid communities in making more effective decisions regarding damage reduction, prioritizing mitigation actions, and preparing for future flood events.

Published: January 2022

Background: Pseudomonas spp is notoriously known to be important agent of hospital as well as community acquired infections. These organisms are resistant to many antibiotics by intrinsic and acquired mechanisms making infections difficult to treat. Regular surveillance of infection and antibiotic resistance patterns is necessary for selection of appropriate antibiotics for treatment.
Methods: Non repeating Pseudomonas spp isolated from all clinical samples during the year 2017-2019 were included in the study. Identification of Isolates were done by standard conventional tests and antibiotics sensitivity test was done by Kirby-Bauer disk diffusion method following the CLSI guidelines, 2017.
Results: A total of 42,545 specimens comprising of sputum, blood, pus, urine, body fluids and endotracheal tubes were processed during the entire 3 year period. There was significant increase (p-value <0.05) in yearly isolation rate of Pseudomonas spp i.e. 141(7.95%), 197(12.14%) and 303(15.69%) isolates in the year 2017, 2018, and 2019 respectively. Resistance rates of the isolates to cefoparazone sulbactam, Piperacillin Tazobactam, and Tobramycin was significantly decreasing (p-value <0.05). Overall resistance to ceftazidime (66.13%) was alarming. Decrease in MDR isolates were statistically significant over 3 years e.g. 32(22.69%), 31(15.73%) and 37(12.21%) isolates in the year 2017, 2018 and 2019 respectively (p-value <0.05).
Conclusion: The rate of infection of Pseudomonas spp is significantly increasing. There was gradual decrease in number of resistant isolates and MDR isolates over the peri-od starting from 2017 to 2019 which is a favorable trend. The possible factors playing role have to be further studied, identified and promoted.

Authors: Avramenko Valentyna
Published: January 2022

The article reveals the essence of the following concepts: “competence”, “professional competence”, “professional terminological competence”, “terminological competence of future economic specialists”. The peculiarities of the formation of terminological competence, as a mandatory component of professional training of students of economic education, are highlighted by the author. In particular, the author considers the system of general and professional knowledge as an important component of a competitive specialist, and the level of his professional speech involves mastery of terminological vocabulary. The problem of the formation of professional terminological competence of future specialists in scientific works of domestic and foreign scientists is analysed. The current state of formation of the studied competence in students of economic specialities in higher education institutions is traced in the article. The results of the theoretical study allowed us to formulate the definition of “terminological competence of future specialists in economics”: the ability to accurately, clearly and appropriately use economic terms in the process of professional activity, clearly operate professional terminology, be able to use business management tools, have professional ways to exchange information, use basic methods of information exchange principles of business communication. The author outlines the peculiarities of forming the foundations of terminological competence of future economic specialists. It is determined that knowledge and mastery of specific terminology will ensure success in situations of professional communication, and a low level of mastery of professional speech makes it impossible to adequately understand, objectively assess and thoroughly master students’ knowledge of professional disciplines. Possible ways of increasing the efficiency of terminological vocabulary formation of future specialists are identified. It is proved that the economic terminology system, as well as the terminology of another field of knowledge, is structured using a number of paradigms, such as synonymous, antonymous, paronymic, homonymous. It is concluded that the given exceptional role of terminology in professional activities is important in order to find new methods and organizational forms of training for economic education.

The article notes that the communicative component of the educational process has a great significance for humanitarian education in the field of culture, which is aimed at forming competencies related to creativity and using communication skills. The demand of the society for these competencies actualizes the urgency of studying the experience of using online educational platforms in the educational process of cultural and artistic education, which have significant communicative potential. The article uses such research methods as pedagogical observation and experiment, methods of analysis, synthesis and generalization. The scientific novelty of the study is to highlight the experience of the department in attracting online educational platforms to work with students during lectures (on the example of teaching in terms of distance learning). It is found that the use of the Mentimeter platform, which is used by lecturer while working with students during lectures both for educational purposes and getting feedback from students about the content of the course or lecturer’s methodological developments, significantly increases the interest of students in the materials of educational course and the learning process in general. Online surveys, created employing the platform, provide an opportunity to establish synchronous communication with students during lectures, which is extremely important for both full-time and distance institutional education. Students’ assessment of the communication and educational components of distance learning has much higher rates. Communicative practices in the educational process in the context of the pandemic are important not only for learning but also for the harmonious development of personality and overcoming the socio-psychological challenges of the time.

From 3 to 10% of the poultry in the process of growing and keeping dies from one reason or another (illness, cannibalism in the herd, etc.), and the disposal of such a bird is now a big problem for many poultry farms. Current practice involves its burial in the so-called “Czech pits”, burning or processing in autoclaves, which requires significant costs and can lead to environmental pollution. Composting such a bird is much cheaper, but it also raises the concerns of some specialists regarding the possible negative impact on the environment. The purpose of these studies was to study the kinetic laws of the composting process of dead birds, its impact on the environment, the quality and safety of the compost obtained. An experiment was conducted in which the corpses of birds were composted together with litter droppings in a ratio of 1: 6 in two versions: without treatment with a microbiological preparation (D1) and a treated microbiological preparation (D2). Option (K) was used as a control, in which the litter was composted without the addition of poultry corpses and treatment with a microbiological preparation. It was found that in the process of composting, the temperature of the raw material reached 64-66 °C, the duration of the period with temperatures of more than 60 °C was 5-9 days, which according to previous studies is enough to neutralize most types of pathogenic microorganisms. Processing the raw material with a microbiological preparation contributed to an increase in the temperature of the substrate in individual periods of the active composting phase by 1-5 °C and a decrease in ammonia emission by 1.1-1.2 times. In both cases (D1 and D2), almost complete decomposition of the corpses of birds was ensured for 45 days. Composting the litter together with the dead bird allowed to increase the nitrogen content in the finished compost. In all cases, bacteria of the genus E. coli and Salmonella were not found in the finished compost.

The historical aspects, significance, peculiarities of ostrich behavior and occupational safety of ostrich farm workers are analyzed. It is noted that ostrich farming began in the world in the late XIXth century. The authors study the domestic and foreign practice of stausivnytstva. Describes the significant contribution of the industry in obtaining ostrich products – leather, meat, eggs, feathers. The value of staus products in comparison with other species of animals is noted. It is emphasized that during the care, feeding and observation of ostriches it is necessary to follow the established precautions. An ostrich can kick from bottom to top with a force of 30 kg per 1 sq. km. With one blow it can easily injure the worker. It has been established that ostriches are quite aggressive during the reproductive period – they can take the employee as an opponent with all the negative consequences. It is noted that during work with adult ostriches (transfer to another place, loading into vehicles, carrying out of medical and preventive actions, etc.) for calming of a bird apply a special hook not less than 2 m long by means of which its head presses to the earth, and then put on an opaque hood on his head. Ostriches can be caught in the appropriate gutters, grabbing them by the head with a hook or hands. Experienced handlers use a number of specialized tools, including boards, hooks and limiters. Due to the risk of injury to birds or humans, ostriches should be handled by an experienced worker. It is noted that it is better to walk a bird to three workers, one holding each wing and one pushing from behind. Ostriches require a very good fence, as they can slip through or go over strung-wire stock fences. Measures to prevent injuries to workers during the care and breeding of poultry are described. It is noted that breeding ostriches is one of the most profitable businesses in agriculture.
« On est quelque part des athlètes d’entreprise »

Dans cet article, les auteurs s’intéressent à ce qui retient durablement les auditeurs expérimentés dans les grands cabinets. À partir de l’analyse de vingt-cinq entretiens, ils montrent que ces derniers peuvent faire l’expérience de réparations affectives soutenant leur engagement. Ils définissent ces réparations affectives comme un ensemble d’émotions capables de compenser la difficulté du métier, par la satisfaction d’avoir délivré, de s’être dépassés et découverts des liens indéfectibles avec les autres. Leurs résultats éclairent une dimension méconnue du métier et contribuent à expliquer son attractivité malgré les menaces qui l’entourent aujourd’hui.
La loi Copé-Zimmermann, quels impacts sur le profil sociologique des administrateur(rice)s du CAC 40
Authors: Ferrary Michel
Published: January 2022

La loi Copé-Zimmermann de 2011 impose un quota minimum de 40 % d’un même sexe dans les conseils d’administration (CA). Elle illustre le rôle des pouvoirs publics et de la contrainte légale pour promouvoir la mixité femmes-hommes au sein des instances de gouvernance. L’analyse de la loi suggère que sa genèse a été influencée par la contrainte sociétale et sa mise œuvre par l’état du marché du travail. La loi a eu des effets de débordement imprévus en s’accompagnant d’une évolution des caractéristiques sociologiques des membres des CA. Cela s’est notamment traduit par la convergence des profils des administrateur(rice)s et une baisse du nombre d’administrateurs diplômés des très grandes écoles et des étrangers.

Published: January 2022

The advantages of reduced iron ore pellets over oxidized ones have been considered. The chemical and physical parameters of the primary material have been given: iron ore (magnetite) concentrate (iron content is 67.30 mass %; particle size distribution is 97.0 % of 0.056 mm fraction), bentonite (montmorilonit content is 70.43 mass %; particle size distribution is 94.5% of 0.056 mm fraction), ground coke. The course of experiments has been described. The zonal structure of the obtained pellets has been characterized: the central zone is composed of hematite with relics of magnetite; intermediate one contains magnetite particles with inclusions of hematite; peripheral zone includes subidiomorphic crystals of magnetite and their dendritic aggregates. The bentonite component in the central and intermediate zones retained a crypto-crystalline structure, in the peripheral one it had been transformed into a crystalline aggregate of garnet and pyroxene. Emphasis is placed on the need to verify the impact of various indicators of temperature, firing time, quantitative ratios of charge components, mineral and chemical composition of the cementing material on mineralogical transformations.

Розглянуті результати дослідження залежності міцнісних характеристик руд і вмісних порід, стійкості підроблених гірничих масивів від мінералогічних показників. На прикладі Первомайського й Ганнівського родовищ Північного залізорудного району Кривбасу показано, що головними мінералогічними чинни-ками міцності руд і порід є твердість мінералів і ступінь досконалості їх спай-ності. Важливе значення мають також їх структура й текстура. Наведена класифікація магматичних, метаморфічних, метасоматичних, тектонічних, осадових, гіпергенних утворень, які складають продуктивну та вмісні товщі родовищ, за показниками стійкості розкритих гірничих масивів.

Приведены результаты геохронологических и геохимических исследований интрузий гранодиоритов западной части Мангушского синклинория. Показано, что U-Pb возраст гранодиоритов по сфену 2024±6 млн. лет. Согласно геохи-мическим характеристикам, гранодиориты могли образоваться в коровом магматическом источнике, в реститовой фазе которого были, вероятно, кли-нопироксен, амфибол и плагиоклаз. Среди плагиогранитоидов западной части Мангушского синклинория выделены ранние тоналиты каратюкского комплек-са, возрастом 2,13 млрд. лет, близкие по составу к ТТГ (тоналит-трондьемит-гранодиорит) адакитового типа, и более поздние (2,024 млрд. лет) гранодиориты, образовавшиеся в коровом магматическом источнике. Формирование интрузий палеопротерозойских плагиогранитоидов может быть связано с субдукцией океанической коры, разделявшей Сарматский и Вол-го-Уральский коровые сегменты около 2,1 млрд. лет назад.
