Authors: Mallikarjuna M V , Ali Zeeshan , Ahmed MD Zain , Kulkarni Vishnuteja , P Rathnakumar , Nagaral Madeva
Published: June 2022

Increased interest in polymer composites filled with natural organic fillers, fillers derived from renewable sources and biodegradable, has resulted from growing concern about environmental concerns and, on the other hand, the desire for more adaptable polymer-based materials. The composites, which are often, referred to as "Green," have a wide range of industrial uses. This research conducts a literature assessment in the wide field of green composites in order to identify materials with the potential to be used on automobile body panels in the near future. Materials derived from renewable resources will be favoured over finite fossil goods from now on. When the polymer matrix is biodegradable and originates from renewable sources, these composites may be even more environmentally beneficial. This rapid overview (with no pretence of exhaustiveness over such a big issue) demonstrates the major routes and findings of study (both academic and industry) on this relevant subject, as well as acceptable sources for further in-depth studies.

Authors: M Sh Mokhtar , AW Radwan , MA Fakher , MA Khalil , Sh Y Abd Elraouf , LH Abu kamar
Published: June 2022

Introduction: Age is linked to an increase in the incidence of a variety of diseases and disabilities, as well as a loss in the functional reserve of numerous organ systems and a gradual reduction in personal and social resources. A serious shortage of intensivists and ICU beds is expected as a result of existing unitization practices. In 2006, approximately 50% of all admissions to intensive care units were elderly patients, and those patients consumed 60% of all ICU days. Further, during the last 6 months of life, ICU days account for 25% of all Medicare dollars spent. Aims: This study aimed to predict the risk factors of intensive care unit mortality in critically ill elderly patients ≥65 years old with special emphasis on age as a predictor of poor outcome. Methodology: This is a retrospective cohort historical study carried out for one year from January 2015 to January 2016 at the intensive care unit of Teaching Hospital, Menoufia Governate. A total of 800 consecutive patients were included over 12 months, 402 (50.2%) were male and 398(49.8%) were female aiming at assessment of risk factors of their in-hospital mortality with special emphasis on age as a predictor of poor outcome. Results: There were statistically significant differences between survival and mortality among patients regarding cardiac, renal and electrolyte disorders, neurological and gastrointestinal disorders, MPM II predicted death rate, hematological and oncologic disorders except Hematological malignancy and pulmonary disorders except Airway diseases. Conclusion: Anemia, thrombocytopenia, non-hematological malignancy, systolic blood pressure≤90 at admission, C-reactive protein (CPR) prior to admission, vasopressor infusion, and mechanical ventilation were the independent risk factors associated with raised mortality in elderly patients. We should adopt measures to decrease the incidence of these complications to try to reduce mortality. A better comprehension of factors associated with death in the elderly can improve medical care to these patients.

Published: June 2022

Introduction: Oral cancer is the most prevalent and globally fifteenth-most reported cancer worldwide, as per International Agency for Research on Cancer (IARC). Several forms of oral malignancies are recognized clinically and pathologically, although oral squamous cell carcinomas (OSCC) account for 90% of all oral cancers. Aim: To find out whether socioeconomic factors and clinicopathological traits may play a role in the development of oral squamous cell carcimoma (OSCC). Methodology: A total of 197 individuals were incorporated in the study who were diagnosed and treated in the ENT department. A systematic questionnaire was used to collect clinicopathological and socioeconomic data. Descriptive analysis was used for socioeconomic status (SES) and demographics, whereas regression analysis was used to establish a link between SES and tobacco chewing practices, tumor size, and stage. Study design: A cross-sectional study. Place and Duration: This study was conducted at Jhalawan Medical College Khuzdar Pakistan from January 2021 to December 2021. Results: We found a higher prevalence of males, -+++-++-and the average age of patients with OSCC was 43.6 ± 12.2 years. Most of the individuals had a low SES status, and 76.6% chewed tobacco and related substances regularly. Tobacco chewing behaviors or consumption of Smoke Less Tobacco (SLTs) products were substantially connected with gender (male) and SES (p<0.05). The late-stage presentation of OSCC was strongly linked with middle age, tobacco chewing behaviors, and education (=0.05). Conclusion: Most OSCC cases were male patients in their forties from low socioeconomic backgrounds who had a long history of tobacco chewing practices. Tobaccochewers’ most prevalent tumor site was the buccal mucosa, and the majority had advanced malignancies.
The “War Alert” in the Middle East in 1923: The Story of a Forgotten Crisis
Authors: Fomin Alexander
Published: June 2022

This article focuses on a previously unexplored episode in the history of international relations, related to the temporary suspension of the Lausanne Conference on the Middle East in February 1923, which threatened to revive a state of war between Turkey and the Entente powers. This crisis, which unfolded at the same time as the Franco-Belgian occupation of the Ruhr, had a significant impact on the final outcome of the peace settlement in the Middle East enshrined in the Lausanne Treaty. The aim of the article is to determine the place and role of this crisis in the process of establishing a new system of international relations after the Great War and its interconnection with other major events and processes of this period. The author consecutively analyses two phases of this crisis, the first relating to the Turkish demand for the withdrawal of the ships of the Allied Powers from its ports, and the second to the sharp aggravation of the situation on the Turkish-Syrian border. The crisis demonstrated the inability of France to defend its interests in the Middle East “single-handedly” and its forced dependence on British policy. Thus, its role in the development of international relations in the Middle East was similar to that played by the Ruhr Crisis in Europe. The paper draws on numerous sources, primarily British, French and Italian diplomatic documents.
The Foreign Policy Orientation of the Russian Officers and the Factors of the Formation and Failures of the White Movement: Formulating the Problem
Authors: Posadsky Anton
Published: June 2022

The article examines the political and military orientation of the Russian officer corps after the October Revolution of 1917. Drawing on a wide range of ego-sources, the question is posed as to the validity of the widespread version of the outcome of the Civil War and the fate of the White Movement. The disintegration of the Russian army and the subsequent fragmentation of the vast body of the Russian Empire predetermined a change in the position on the “Russian question” of all the main participants in the Great War, above all Britain, France, Germany, and to a certain extent the United States and Japan. Military considerations dictated the active participation of these countries in the struggle around a potential Eastern Front on the territory of the former Romanov's Empire. The Russian officer corps was also forced to determine who they wanted to support – the German side, the Allies and/or the Soviets. The article provides a general characteristic of the composition and state of the corps by the autumn of 1917 and its further evolution, identifying the factors that predetermined this or that choice. The authors analyse the distribution of political and personal predilections of officers with regard to foreign policy orientation. They examine the full range of motivations for choosing an orientation in the circumstances of 1917–1918 and partly in 1919 for different categories of officers. The question of the motives of those officers who chose the path of “national” self-determination is addressed. Each case is illustrated with examples of prominent officers of the rank of general and officers of the staff. In conclusion, the authors chart the trajectories for further research on the subject of political orientations among Russian officers in exile, up to the end of the Second World War.
The Experience of Deaconesses in Europe as a Basis for Organising a Marfo-Mariinsky Convent of Mercy
Authors: Gromova Anna
Published: June 2022

The article explores the attempt to revive the order of deaconesses, which existed since antiquity, by Grand Duchess Elisabeth Feodorovna in the Marfo-Mariinsky Convent founded by her in Moscow, in Russia at the beginning of the twentieth century. Raised in the European tradition of charity and benevolence, the Grand Duchess Elisabeth transferred her experience of charitable ministry to the Russian land. The article demonstrates that the idea of reviving the order of deaconesses was met with a mixed public reaction. “A Great Undertaking in Moscow” was the title of the article on the founding of the Marfo-Mariinsky Convent by the famous philosopher Vasily Rozanov. At the same time Bishop Hermogenes (Dolganov) of Saratov was categorically against the institution of deaconesses, mentioning in the heat of the debate that the idea of reviving the order was “muddled with Protestant yeast”. The article outlines the complex process of discussing the question of deaconesses. The Synod considered it in two sessions, in March and November–December 1911. Since the Synod failed to arrive at a unified position, it was decided to postpone consideration of the issue to the Local Council. However, the 1917–1918 Council never had time to reach a decision on the diaconesses, as its sessions were discontinued under pressure from the Soviet authorities. The question of re-establishing the order of deaconesses on a full scale is not on the current agenda. Nevertheless, the experience of early twentieth-century Russia is quite relevant and needed today.
The Test of Patriotism: Germany in the Perception of the Baltic Germans during the First World War
Authors: Bahturina Alexandra
Published: June 2022

The article examines the attitude of the Baltic Germans towards Germany during the Great War. With the outbreak of the war, the Baltic Germans were forced to define their position towards their ethnic homeland, which had gone into war with the Russian Empire. The Baltic Germans' perception of Germany is reflected in a wide variety of sources, resulting in diametrically opposite assessments. The aim of the article is to provide a comparative analysis of official documents of the Ministry of Internal Affairs, the Council of Ministers, ego-sources, and applications for Russian citizenship from “enemy subjects”, to identify different attitudes towards Germany among the Baltic Germans, which were shaped by a variety of factors, including the anti-German activities of the Tsarist government, general imperial measures prompted by the war, and emotional assessment of what was happening. Previous studies have examined the views of the Baltic Germans mainly on the basis of Russian periodicals and the writings of nationalist publicists. This has left the complex process of searching for the boundary between loyalty to the Russian Empire and attitudes towards Germany, the country of their culture and mother tongue, among the Baltic Germans, outside the realm of research interest. This article aims to fill this gap. The study suggests that the patriotism of the Baltic Germans did not extend so far as to actively and publicly demonstrate rejection of their historic homeland. A considerable proportion of the Baltic Germans sought to strike an acceptable balance between their Russian citizenship and their German background, while attitudes towards Germany among them varied, depending on social background, degree of attachment to Russia and other factors.
“The Slavs are Invincible”: Otto von Bismarck’s Fictional Statements in Contemporary Russia
Authors: Vlasov Nikolai A.
Published: June 2022

The author focuses on the phenomenon of fictitious quotations attributed to the German statesman Otto von Bismarck, which are common in contemporary Russian information space. This topic, as well as the problem of fictional quotations of historical figures in general as a form of collective memory of the past, has not yet been the subject of independent research. The goal of the present article is twofold. First, to identify the role and function of quotations falsely attributed to Bismarck in contemporary Russian information space. Secondly, to examine the reasons for attributing these statements to the Iron Chancellor, i.e. Bismarck's place in contemporary Russian historical memory. To this end, a wide range of materials have been drawn upon, from scholarly works and press articles to online entertainment texts that contain fictitious quotations ascribed to Bismarck. The author concludes that the key thesis of the most popular pseudo-Bismarck statements is the principal invincibility of Russia and the Russian people. Emerged at the turn of the twentieth and twenty-first centuries, they quickly gained popularity primarily within “patriotic” discourse and, due to their widespread popularity, are perceived even by some members of the academia as a well-known truth. The choice of Bismarck as fictitious author of these statements is determined by his position as a “non-friend” in the collective memory, i.e. a foreign figure who had no sympathy for Russia, yet recognised its strength and favoured good relations with it.
European Historical Science of the Late 1930s ‒ Early 1940s: International Connections and Chimeras of Isolation
Authors: Bukharin Mikhail
Published: June 2022

In the late 1930s and early 1940s, European science plunged into a period of regional isolation and the breakdown of established international ties. As a result, rumour replaced reliable verifiable information. A notable case in point was the attempt to celebrate the 70th anniversary of M.I. Rostovtzeff (1870‒1952), a prominent historian of the first half of the twentieth century, who lived and worked in the United States. In the run-up to the anniversary, rumours of the death of Rostovtzeff began to circulate among immigrant historians in Eastern and Southeastern Europe. Unable either to verify reports of his death or to verify that Rostovtzeff was alive, European academic community declined both to commemorate the anniversary and to hold memorial events. Perhaps it was the director of the Kondakov Institute in Prague in 1939‒1945, N.E. Andreev who disseminated rumours about the death of M.I. Rostovtzeff, thus trying to avoid involving the European and North American academic community in the celebration, which would have necessitated publicly soliciting the support of the pro-Nazi authorities of the Protectorate of Bohemia and Moravia, on which the Institute depended. Throughout the period of the II World War, colleagues could not get acquainted with each other’s work. In the post-war period, the structure of European science did not return to the point of the beginning of the crisis of the late 1930s. The new transformation was due to the redistribution of spheres of political influence in Central and Eastern Europe and the formation of new barriers to scientific communication.
Acoustic Analysis Using Symmetrised Implicit Midpoint Rule

Published: June 2022

In wave propagation phenomena, time-advancing numerical methods must accurately represent the amplitude and phase of the propagating waves. The acoustic waves are non-dispersive and non-dissipative. However, the standard schemes both retain dissipation and dispersion errors. Thus, this paper aims to analyse the dissipation, dispersion, accuracy, and stability of the Runge–Kutta method and derive a new scheme and algorithm that preserves the symmetry property. The symmetrised method is introduced in the time-of-finite-difference method  for solving problems in aeroacoustics. More efficient programming for solving acoustic problems in time and space, i.e. the IMR method for solving acoustic problems, an advection equation, compares the square-wave and step-wave Lax methods with symmetrised IMR (one-and two-step active). The results of conventional methods are usually unstable for hyperbolic problems. The forward time central space square equation is an unstable method with minimal usefulness, which can only study waves for short fractions of one oscillation period. Therefore, nonlinear instability and shock formation are controlled by numerical viscosities such as those discussed with the Lax method equation. The one- and two-step active symmetrised IMR methods are more efficient than the wave method.
Role and mechanism of circular RNA circ_0050486 in regulating oxidized low-density lipoprotein-induced injury in endothelial cells
Authors: Zhang Pu , Wang Weiping , Li Meilan
Published: June 2022

BACKGROUND: Dysfunction of endothelial cells in the arterial vasculature is an essential contributor to the pathogenesis of atherosclerosis. Circular RNAs (circRNAs) exert important regulatory functions in endothelial cell dysfunction. Here, we explored the precise role and mechanism of circ_0050486 in regulating endothelial cell injury induced by oxidized low-density lipoprotein (ox-LDL). METHODS: Circ_0050486, microRNA (miR)-182-5p and myeloid differentiation primary response gene 88 (MyD88) were quantified by quantitative real-time PCR or western blot. Cell viability, proliferation and apoptosis were examined by MTS, 5-Ethynyl-2’-Deoxyuridine (EdU), and flow cytometry assays, respectively. Direct relationship between miR-182-5p and circ_0050486 or MYD88 was verified by dual-luciferase reporter and RNA immunoprecipitation (RIP) assays. RESULTS: Circ_0050486 was upregulated in atherosclerosis serum and ox-LDL-treated human aortic endothelial cells (HAECs). Silencing of circ_0050486 suppressed HAEC injury induced by ox-LDL. Mechanistically, circ_0050486 targeted miR-182-5p, and the effects of circ_0050486 silencing were partially due to the upregulation of miR-182-5p. MYD88 was a direct target of miR-182-5p, and miR-182-5p-mediated inhibition of MYD88 attenuated ox-LDL-evoked HAEC injury. Circ_0050486 bound to miR-182-5p to regulate MYD88 expression. Additionally, the NF-κB signaling pathway was involved in the regulation of circ_0050486/miR-182-5p/MYD88 axis in ox-LDL-treated HAECs. CONCLUSION: Our study identifies the functional role of circ_0050486 in ox-LDL-induced endogenous cell injury and establishes a mechanism of circ_0050486 function by affecting MYD88 through competitively binding to shared miR-182-5p.

Published: June 2022

Optimization algorithms are being widely applied in real-time applications. In recent times, Jaya and Rao algorithms have been prominent. The performance of these algorithms will be analyzed for the objective function. The results thus obtained are more accurate and fast compared to previous algorithms. Also, Jaya and Rao algorithms will be utilized for linear array antenna synthesis for the arrays that are equally spaced. Therefore it is of present interest to evaluate the performance of linear antenna array using these algorithms.
Threats and violence towards urban bus drivers in Sweden’: Drivers experiences and general recommendations to prevent violence and threats
Authors: Anund Anna , Ihlström Jonas
Published: June 2022

BACKGROUND: Approximately 30% of Swedish urban bus drivers report having been exposed to threats or violence. As 50% of drivers have voiced concerns about the occurrences, threats and violence also represent contributing factors to driver stress and fatigue. OBJECTIVE: The aim of this study was to explore bus drivers’ experience of threats and violence; how threats and violence manifests and how the problem is handled by drivers. Gaining understanding of the circumstances is important to reduce the number of threats and violent incidents to provide healthy and attractive working conditions for drivers. METHODS: This study is based on in-depth interviews with 12 urban bus drivers in the City of Malmö in Sweden. RESULTS: Urban bus drivers experience threats daily from passengers, although physical violence occurs less often. The most common situations resulting in threats involve asking passengers to show valid tickets, denying child carriages onboard and running late to a bus stop. The drivers have not received clear guidelines as to strategic handling of the invalid ticket situation. CONCLUSIONS: Recommendations include a clear policy and consensus with regard to handling invalid tickets, providing drivers with guidelines for appropriate procedures for passengers refusing to pay, improving reporting routines and establishing a strategy for the Public Transportation provider and operator to follow with regard to reports, in-vehicle surveillance cameras including informing passengers that they are being video recorded as well as harmonizing the location of alarm buttons on buses.

Authors: Abareshi Fatemeh , Salimi Fatemeh , Farnia Faezeh , Fallahi Majid , Rastaghi Sedigheh
Published: June 2022

BACKGROUND: Job burnout syndrome is caused by prolonged exposure to difficult working conditions. Emergency medical services (EMS) staff are exposed to varying levels of mental workload (MWL) depending on the operation, so it is more likely that they experience burnout syndrome. OBJECTIVE: The main aim of the current research was to investigate the effect of MWL, work-related and socio-demographic factors on job burnout among Iranian EMS staff. METHODS: The current cross-sectional and descriptive-analytical research was carried out among 198 EMS. In doing so, the Maslach Burnout Inventory (MBI), The NASA task load index (NASA TLX), and an author-developed work-related and socio-demographic factors were distributed among participants to collect data. The data were analyzed using descriptive and inferential statistics (t-test, ANOVA test, multiple linear regression, and Pearson correlation coefficient). RESULTS: The results showed a significant statistical relationship between burnout and MWL. A significant statistical relationship between overall workload and two dimensions of MBI, namely, emotional exhaustion and depersonalization were observed (P < 0.05). Moreover, a significant statistical difference regarding the mean of burnout in the different groups of educational levels and occupational categories were observed. CONCLUSIONS: The EMS staff generally reported moderate levels of MWL and burnout. Findings showed that socio-demographic and occupational factors had little effect on burnout. MWL, education levels, and occupational categories are the main predictors of job burnout.

Authors: Khamaj Abdulrahman M. , Ali Abdulelah M. , Alam Mohd Mukhtar
Published: June 2022

BACKGROUND: Musculoskeletal disorders (MSDs) are the most common work-related injuries identified among caregivers in the health sector as a high-risk group. OBJECTIVES: The study aimed to investigate the factors that influence musculoskeletal disorders among caregiver and to evaluate the relationship between work and non-work related factors with MSDs. METHODS: Data were collected from 104 caregivers using descriptive design and stratified cluster sampling. The survey included a demographic questionnaire and a Nordic Standardized Musculoskeletal Questionnaire. Logistic regression was performed to determine the risk factors associated with MSDs. The Odds ratio (OR) was calculated to define the influence of each risk factors. In addition, we used forward logistic regression analysis to validate the predictive model. RESULTS: In this cross-sectional survey, the results showed that 70 (67.3%) participants reported MSDs. MSD was highest at the lower back (46%), then knee (15.4%) and shoulder (11.5%). The overall success of the prediction is 90.4% (94.6 for having MSDs). The most important risk factors were manual handling (p < 0.001, odds ratio = 45.64) followed by bending (p = 0.008, odds ratio = 39.4). CONCLUSIONS: The results of this study reaffirmed the high prevalence of work-related MSD among caregiver’s primarily in the lower back. The most important risk factors were manual handling, followed by bending / twisting, and handling of an excessive number of patients. Therefore, it is necessary to consider appropriate policies for managing MSDs among caregivers.
EXPLICIT FIFTH-ORDER HYBRID METHODS FOR DYNAMICAL SYSTEMS WITH DELAY
Authors: Pechuk Vasiliy , Bondarenko Nataliya
Published: June 2022

In the paper we consider the systems of delay differential equations, which are mathematical models of many technical processes with delay in time. An explicit fifth-order hybrid method for systems of delay differential equations for the variable step of numerical integration is constructed. This algorithm is based on the most commonly used explicit fifth-order Runge-Kutta methods for ordinary systems of differential equations and the construction of Newton polynomials for the prehistory of the model and Taylor formula. The basic principles of construction of such explicit hybrid methods of higher orders of convergence are given. An accurate estimate of the local error of numerical integration by this method is obtained.

This algorithm allows the use of numerical integration steps greater than the magnitude of the delay or procedures for adjusting the magnitude of the step depending on the calculation error. Such a problem of numerical integration of time-delay dynamical systems occurs when the time interval is large enough compared to the delay. Implicit continuous Runge-Kutta methods were previously used for numerical integration such problems, which complicated the numerical algorithm, because nonlinear systems of equations have to be solved at each step of numerical integration. The explicit hybrid method constructed by us for systems of delay differential equations is convenient for programming, has a high speed of calculation of numerical solution, in comparison with implicit methods for such models of problems. Also, this method has no restrictions on the magnitude of the delay, in contrast to the hybrid methods with decomposition in Taylor series for delay. The method obtained by us can be used to construct maps of dynamic modes in the study of regular and chaotic behavior of time-delay dynamical systems.
Hydrodynamical instability of newtonian flow of downstream on axisymmetric sudden contraction
Authors: Orel Vadym , Pitsyshyn Bohdan , Matsievska Oksana , Konyk Tetiana
Published: June 2022

Measures to reduce energy losses in pipeline transport systems must be implemented already at the design stage. In particular, this also applies to local resistances of pipelines. In the paper, the separation length and separation height downstream of the contraction plane of axisymmetric sudden contraction of the circular pipe of a single-phase Newtonian flow have been investigated. Area ratios 0.250 and 0.321 were considered. After all, measures to reduce energy losses on the axisymmetric sudden contraction must be effective at values of the area ratio not less than 0.250. The separation length and separation height have the extreme dependence with a maximum at the transition of the laminar flow into a turbulent flow one. When the values of the Reynolds number at the laminar flow increase, these sizes increase, and they decrease at the turbulent flow. In the first case, the separation point is shifted downstream from the plane of contraction. The separation length and separation height are proportional to the Reynolds number. This is similar to changing the separation length and separation height of upstream from the plane of contraction. A transition zone be located between 9650 and 40000 and 1200 and 5000 if the Reynolds number is based on smaller pipe diameter and step height correspondingly. The separation length of downstream of the contraction plane are decreased if these sizes are length - smaller pipe diameter ratio, and increase if these sizes are length - step height ratio. The changing of separation height is similar. But the change of the separation length is greater than the change of separation height. There is enough good agreement between the experimental results and the results described in the literature. For taking measures providing decrease in energy losses, the investigation of the separation length and separation height downstream of the contraction plane at different values of area ratio being more than 0.250 is proposed.
Study of changes in groundwater quality indicators during operation of water intake well
Authors: Khomutetska Tetiana , Arhatenko Tetiana
Published: June 2022

Groundwater is one of the main sources of providing people with drinking water. However, during the period of operation of water wells, the quantitative and qualitative characteristics of groundwater change significantly. These changes depend on many factors of natural and man-made origin, in particular, depletion of reserves, conditions of operation and construction of wells, anthropogenic impact on the environment and so on. To assess the water quality of the underground source intended for water supply of one of the facilities in Kyiv, a number of studies of the quality of water extracted from a well 67 m deep were compared. Experiments conducted after the well in 2010 and 2021 were compared. The analysis of the obtained results showed changes in the indicators of groundwater quality during the well operation, which relate to water turbidity, color, total hardness, dry residue, total iron and manganese content.

In the current operating conditions of the water intake, the groundwater raised to the surface does not meet the current regulatory quality requirements, and therefore it needs to be purified before it is delivered to consumers. For this case and the need to provide water to a small facility, it is recommended to use the technology of deironing water by biological oxidation. The use of a bioreactor with an insoluble carrier and a contact-clarifying filter with expanded polystyrene loading is proposed. The technology has shown high efficiency in both laboratory and production conditions for local water mains.

The effect of this plant study was determined by the application of different nutrient solutions and increasing doses of dry mass and pots potential on aerial production of corn plants grown in a sample content of a Red-Yellow Latosol in pots under greenhouse conditions. The treatments consist of three nutrient solutions, the treatments of additional doses (K) and a solution that received neither nutrient nor K application. The root quadratic model is the most suitable among the results to describe a dry mass production of corn plants as a function of the K dose.

Background. The geological structure of the Laptev Sea basin is characterized by a rift nature, thus providing no favorable conditions for the presence of hydrocarbon accumulations. However, the lack of seismic information and the absence of well drilling indicate an incomplete stage of the basin exploration.

Aim. To analyze the results of geological modeling based on structural mapping and to identify promising areas of hydrocarbon exploration. A geological hydrocarbon study of the Laptev Sea basin was carried out in order to recommend areas for licensing, as well as to identify exploration drilling sites and estimate the total initial prospective geological resources according to the conducted numerical basin modeling. To design sedimentation models and predict reservoir properties in the Laptev Sea basin.

Materials and methods. The analysis was based on the data retrieved from production reports for individual large objects in the water area. A model developed by Equinor specialists was used for the basin analysis. The results of hydrocarbon system modeling, the prediction of hydrocarbon saturation obtained from sections of two sample profiles while structural mapping of the basement and top of Oligocene-Miocene sediments were used.

Results. Prospective areas of accumulation of hydrocarbons and their confinement were determined. The probability of hydrocarbons in non-anticlinal traps was estimated. Priority areas of hydrocarbon exploration within the unallocated subsoil area were identified. Recommendations for further geological exploration across the license area were formulated.

Conclusion. Further exploration of the Yuzhno-Laptevomorsky promising area is recommended by means of analyzing the available data, processing of new geophysical data, updating the geological model and designing 3D seismic surveys within the identified promising areas. In addition, 2D seismic surveys at the regional level should be carried out to define the sedimentary boundaries of the Eastern Artic water area.

Efficacy of therapeutic measures for chorioptosis of cattle
Authors: Kovalenko S.
Published: June 2022

Skin diseases in farm animals are most often caused by ectoparasites, which are complex with the host. Chorioptosis of cattle is caused by skin mites of the genus Chorioptes, Chorioptes Bovis, which occupy a significant place among ectoparasites and cause great economic damage to livestock, has become widespread. Effective control and protection of animals against chorioptosis requires the development of highly effective insecticides, the therapeutic and economic feasibility proven by experimental studies. The study aimed to study the therapeutic efficacy of modern drugs for chorioptosis of cattle, taking into account the method and frequency of use of chemicals and active substances that are part of them. Experimental testing of domestic and foreign drugs for Chorioptes Bovis: brovermectin 1 % (DR – ivermectin), sebacil 50 % (DR – foxim), neostomazan (DR – transmix, tetramethrin). The leading indicators of the effect of drugs were extensibility and intensity. According to the results of the studies, it was found that the most effective drugs for spontaneous chorioptosis of heifers were drugs brovermectin 1% and sebacil 50% with three times their use with an interval of 10 days. Their extensibility and intensity efficiency at 25 and 30 days, respectively, was 100%. With double use of these drugs, the therapeutic efficacy (EE and IE) decreased, and on the 60th day of the experiment, brovermectin was 1 % – 66.67 and 87.82 %, sebacil 50 % – 53.30 and 82.04 %, respectively. The use of neostomazan in chorioptosis patients did not lead to their complete recovery. With double use of the drug on the 60th day of the experiment, the indicators of extensibility and intensively were 40.0 and 89.59 %, with three uses – 60.0 and 89.59 %, respectively. The obtained research results recommend brovermectin 1 % and sebacil 50 % to effectively carry out treatment and prevention measures for chorioptosis in cattle.

A SYSTEMIC-FUNCTIONAL APPROACH IN LINGUISTIC ANALYSIS (ON THE EXAMPLE OF TWO ONLINE ARTICLES ANALYSIS RECOUNTING THE 2014 CRIMEAN REFERENDUM FOLLOWING THE RUSSIAN ANNEXATION)
Authors: Кульчицька Олена , Браун Веслі
Published: June 2022

a comparative analysis of two texts recounting the 2014 Crimean Referendum following the Russian Annexation has been conducted through a systemic-functional paradigm in order to examine linguistic features that have been employed to convey bias or impartiality. These texts have been analyzed taking into account M. Halliday's theory, which states that semantics of the text is inextricably linked with grammar, as meanings are realized in language through formulations [6]. In order to trace the meaning of a text, discursive grammar must be both functional and semantic, i.e. grammatical categories must be interpreted as expressions of semantic models. Field, Tenor and Mode are defined as three aspects of the context that influence ideational meaning, interpersonal meaning, and textual meaning respectively. In the given article ideational and textual meanings are examined.
ДИСКУРСНІ СТРАТЕГІЇ ІНШОМОВНОЇ КОМУНІКАЦІЇ: ФРАНКОЗНАВЧИЙ АСПЕКТ
Authors: Теплий Іван
Published: June 2022

У статті висвітлено франкознавчий аспект дослідження у контексті провідних дискурсознавчих стратегій і пошуків, передовсім тих, що належать перу доктора філологічних наук, професора Катерини Яківни Кусько. Доречно вирізнити три магістральні лінії франкознавчого аспекту дослідження стосовно іншомовного дискурсу: дискурс як масивний обсяг текстів, об’єднаних на підставі когнітивних і прагматичних параметрів; дискурс в особистісному вимірі: проблема мовної особистості; поняття інтердискурсу як інтегративного чинника.
