Authors: Hasan Mariwan
Published: May 2024

Ecocriticism is a growing discipline within literary studies that has become prominent as a critical framework for studying the connection between literature and the environment. Ecocriticism is a method of analysing texts that helps us understand how literature reflects and influences cultural views of the natural world. It has gained popularity due to growing environmental concerns. This research examines the reoccurring nature imagery present in Mary Oliver's selected poems, namely "Wild Geese" and her poetry collection, American Primitive, through textual and analytical.  It shows how her poetry acts as a medium for actively exploring and articulating environmental awareness. By conducting a detailed examination of these poems, the researcher’s aim is to decipher the complex and detailed depiction of nature created by Oliver, and to understand the thematic importance of repeating themes. The investigation produces significant discoveries that enhance comprehension of the poet's distinctive approach to ecocritical ideas. Ultimately, Mary Oliver is a poet who has a profound sensitivity for the natural world, establishing a profound bond, promoting introspection, and highlighting the ethical aspects of humanity's interaction with nature.

Expression of a person’s emotional state using phraseological units with a color component in Russian and Persian languages
Authors: Haji Mousaei Svetlana Aleksandrovna , Madaeni Awwal Ali
Published: May 2024

This article is devoted to a comparative analysis of phraseological units with a color component in Russian and Persian linguistic cultures, expressing the emotional state of a person. Color is an integral part of the perception of the reality around us; with its help, we can consciously or unconsciously convey our mood, inner state, and attitude towards everything around us. Phraseologisms, being a stable combination, give speech an emotional coloring and figuratively characterize a particular state. The object of the study is phraseological units of the Russian and Persian languages containing a colorative component, selected by a continuous sampling method from explanatory, phraseological, etymological and encyclopedic dictionaries and other literary sources of the Russian and Persian languages. The main research method used in this work is the comparative method and axiological analysis of phraseological units containing a color component in the Russian and Persian languages. Let us note that work on the comparative analysis of various lexical units is currently being carried out quite actively, but research in the field of comparing phraseological units with the color component of the Russian and Persian languages is not numerous. The scientific novelty of the work lies in the study and understanding of information about the emotional state of a person, which is conveyed by phraseological units of the Russian and Persian languages, containing a color component. Based on the results of the study, the symbolism and associative perception characteristic of representatives of Russian and Persian culture were determined, and the colors included in the phraseological units characterizing the emotional state of a person were identified, and the subjective evaluative attitude of a person to existing or possible situations and the objective world was indicated, transmitted by them.
The realization of the concept of the features of the historical novel by Walter Scott on the example of Barry Unsworth's novel "Moralite"
Authors: Sadovnikova Yuliya Mikhailovna
Published: May 2024

The article examines the features of the concept of the historical novel by Walter Scott on the example of Barry Unsworth's novel "Morality Play". The purpose of this article is to identify the features and principles of the historical method. The great merit of the outstanding Scottish writer Walter Scott (1771-1832) is that he introduced the principle of historicism into literature and wrote a number of brilliant historical novels. In them, readers see a picture of the struggle of contradictory and complex interests of various social groups, parties, and religious sects. His historical novels provided a better understanding of contemporary issues. He combined historical truth with fiction, explaining the validity of such a connection by saying that “the most important human passions in all their manifestations, as well as the sources that feed them, are common to all classes, states, countries and epochs; hence it invariably follows that although this state of society affects opinions, way of thinking and the actions of people, these latter are extremely similar in their very essence. Walter Scott was the founder of the historical novel in its modern sense. In the XIX century, he developed the principles of the historical method, which made it possible to create fascinating novels, freed from excessive archaization of language and at the same time fully conveying the originality and recognizable imprint of the described epoch. In the 19th century, along with the tradition dating back to Walter Scott, another form of aesthetic insight into the past also asserted itself. Real historical characters in such works are optional, although their presence is not excluded. The "hero" for the writer is not a historical event, but an "epoch". The author of such a work creates his own self-sufficient world, achieves credibility not by more or less accurately following historical material, but by the reality of the psychological experience of the characters, the reality (often illusory) of everyday life. The novel "Morality Play" is a historical detective novel by British writer Barry Unsworth, was published in 1995, and was first published in Russian in 2005. The novel is an example of a fruitful combination of two updated genres: new historical fiction and metaphysical detective.
The frequency of the use of the word "Tibet" in the Russian-language discourse of the 18th and 20th centuries.
Authors: LUO XUE
Published: May 2024

The analysis of the reasons for the appearance of the "three peaks" of the use of the word "Tibet" from the 18th century to the present day in the national corpus of the Russian language is made in the article. Author, by considering the compatibility with the word "Tibet" in text materials, draws conclusions about the dynamic perception of the image of Tibet by native speakers of the Russian language. The article examined the image of Tibet based on materials from the NKRR. The author highlights such characteristics of the image of Tibet as the complexity of the location, the difficulty of the path, the connection with the religious and mystical worldview, mystery, etc. The analysis of the process of designing the image of Tibet reflects the development of relations between China and Russia. We used the main body of the NCR to analyze the uses of the word "Tibet" from the 18th century to the present day. The number of word usage shows three so–called "peaks" occurring in 1740-2000. The research is based on frequency and description. The frequency method helps to determine the number of word usage in different years and identify three "peaks" of the use of the word "Tibet". The descriptive method allows us to trace the peculiarities of the use of the word "Tibet" at the moment. It was revealed that the first peak of the use of the word Tibet was at the end of the 19th century. At the end of the 19th century, Tibet was an unknown region for Russians. The design of the image of Tibet is helped by textual information coming from scientific and trade expeditions. Most of the words combined with the word Tibet set the vector of movement to a new country for Russians. The second peak of word usage occurred in 1926. At this time, Russian people's knowledge of Tibet became deeper in the aspects of religion and tourism, and the description of Tibet became more detailed. During the third peak of word usage (2009), with the continuous development and popularization of Tibetan culture in Russia, more and more attention is paid to describing the image of Tibet, and there are more and more works dedicated to Tibet, advertisements for Tibetan clinics, travel blog texts about Tibet. Thus, the study of the image of Tibet is relevant for modern linguistics. The materials of the article can be used to develop educational materials, and will also be useful in studying the dynamic aspect of the worldview.
"Hello, girlfriend": an advertising narrative in the context of a visual turn (using the example of Wrigley's and Dirol brands)
Authors: Platitsyn Aleksandr Vladimirovich , Arepjev Andrei Valentinovich , Golovanov Aleksandr Nikolaevich
Published: May 2024

The subject of the research is the materials of advertising campaigns of brands-manufacturers of chewing gums Wrigley's (1930) and Dirol (2008). The object of the research is the specificity of the advertising narrative in the context of an appeal to the optical language of communication. The authors examines in detail such aspects of the topic as the narrative structure of the advertising text and visual means of presenting visual images. Special attention is paid to the dynamic context of the visual turn, as well as the main aesthetic characteristics of advertising materials at different historical stages. The subject of this article is considered from the point of view of changing the communicative paradigm, mixing verbal and optical on the screen plane. The main directions related to the new visual reality are noted, thanks to which the importance of aesthetics is determined, the degree of its influence on current media text formats. The research methodology is based on general scientific methods of working with media text, in particular on descriptive and contrastive methods. Also, within the framework of the subject analysis, a range of general philological methods is used, including transformational, contextual and semantic-stylistic methods. The novelty of the research lies in the articulation of the aesthetic components of the analysis of a modern advertising product. The main conclusions of the study are the observation and interpretation of the motive of duality within the advertising narrative, as well as the syncretic nature of the iconic image and the subjective perception of the viewer. The media text appears as a means of releasing the image from the external field and integrating it into the aesthetic experience of the recipient. The authors' special contribution to the research of the topic is the generalization of two key dimensions of the advertising text (narrative, visual) and the formulation of objective criteria that allow us to detect patterns in advertising narratives (repeatability of the plot, variability of visual means, identity of advertising objects, the presence of sufficient historical distance). The possible directions of future research on visual turn in various industries, including television and cinema, are emphasized.

To investigate the process of drying wheat grain under conditions of combined acousticvacuum exposure, a mathematical model of the process under consideration was developed based on differential equations. Preliminary numerical experiments were carried out using the developed mathematical model. The results of mathematical modeling were obtained in the form of dependencies of changes in mass, temperature and humidity of wheat grain both under separate acoustic and vacuum exposure, and under combined acoustic-vacuum exposure. The drying rate of wheat grain was determined, which is 0.01 g/min under acoustic exposure, 0.19 g/min under vacuum exposure and 0.28 g/min under acoustic-vacuum exposure.
ESTIMATION OF SIMULTANIOUS ANGLE AND PARALLEL MISALIGNMENT AND IMBALANCE OF SHAFTS RELYING ON VIBRATIONAL SIGNALS
Authors:   Belarussian state university of informatics and radioelectronics, Minsk, Belarus, Kechik D. A.
Published: May 2024

One of the important tasks of non–destructive testing of rotary mechanisms is to determine the degree of shaft misalignment. Currently, the misalignment is detected based on the analysis of the amplitude spectrum of vibration. Experimental data show that the amplitudes of the vibration components depend on the displacement of the shafts according to a law close to linear, but with different coefficients of proportionality. The coefficients depend on the design of the coupling, and are usually unknown. In well-known works, the vibration of centered shafts is modeled as a rule by introducing forces into the system at different frequencies of equal amplitude. This does not agree with the observational data, in particular with the different dependence of the amplitudes of the components on the magnitude of the misalignment. In addition, there are usually several sources of forces in the system. In particular, parallel and angular misalignment can be expressed simultaneously and create oscillations at three harmonics of the rotor speed. The imbalance of the rotor leads to the appearance of oscillations at the frequency of its rotation. The oscillations can only be summed vector-wise, i.e. taking into account the phase. Without taking into account the phases of the vibration components, it is impossible to make a correct conclusion about the magnitude of the defects present. In this paper, a method is proposed for calculating the magnitude of the parallel alignment of the shafts and the imbalance of one of them

Numerical solution of the systems of linear equations (linear system), especially in case of nonstationary problems, takes a significant part of computer time. Normally, for solving linear system the applied program packages use either Chebyshev iterative method (wave linear problems etc.), which requires setting the optimal parameter, or gradient iterative schemes, which do not require the initial setting of the optimal iterative parameter and the system matrix self-adjointness. For the systems of linear equations Chebyshev method is optimal in terms of convergence rate (theoretically not improvable) if the system matrix is selfadjoint and positively defined. The only downside of this method is the requirement to know the spectrum boundaries for the equations matrix being solved. This paper proposes the numerical test of the Chebyshev method stability both in classical variant and in the form of multistep scheme.

Authors:   Samara National Research University, Samara, Russia, Krikunov M. M.
Published: May 2024

The work presents simulation of dynamics of a spacecraft~(SC) with variable mass. A generalized method for analyzing the phase trajectory curvature is used, being refined for the case in which the moments of forces applied to the SC depend on the angular velocity. Special cases are considered along with analyzing a spacecraft with dynamic asymmetry. Using the method, the presence of complex evolutions of angular motion is shown, in which the jet stream of the engine creates Coriolis effects (Magnus effect), destabilizing the precession cone and leading to an increase in the nutation angle.

A traction measurement stand based on the aerodynamic method has been developed. To test the stand, a prototype electric rocket engine was used as a cold gas engine. The working medium was nitrogen gas. At a flow rate of 1.2 mg/s, the thrust value was from 0.674 to 0.736 mN, at a flow rate of 1.7 mg/s, the thrust value was 0.934-1 mN and at a flow rate of 2.6 mg/s, the thrust value was from 1.59 to 1.634 mN. The experimental specific thrust impulse was at a flow rate of 1.2 mg/s from 574 to 613 m/s, at a flow rate of 1.7 mg/s from 549 to 588 m/s and at a flow rate of 2.6 mg/s from 612 to 623 m/s. According to the measured pressure values in the chamber of the prototype electric rocket engine, the values of the ideal flow rate of the working fluid from the nozzle were obtained, which amounted to 661 m/s at a flow rate of 1.2 mg/s, 667 m/s at a flow rate of 1.7 mg/s and 674 m/s at a flow rate of 2.6 mg/s. The obtained values of the specific thrust impulse do not contradict the previously obtained experimental data on cold gas jet engines using nitrogen as the working fluid, and also do not exceed the ideal design flow rate

Objective: To analyze the association between epidemiological and clinical factors and the severity of scorpion accidents in children and adolescents. Methods: This is a retrospective cross-sectional quantitative study that analyzed 648 medical records of patients aged between zero and twelve years. The outcome variable was the severity of scorpionism, with bivariate analysis (Pearson's chi-square test) and Poisson multivariate analysis to identify associated factors. Results: A total of 34.7% of the cases were severe, predominantly in female children, under three years old, non-white, urban and from Montes Claros. The majority of accidents occurred before 5pm, on the lower limbs, with care provided after 1am. Sequelae (PR=1.75; 95%CI 1.00-3.05) and ICU (PR=2.45; 95%CI 1.23-4.88) were associated with severity, while bites to the lower limbs reduced the prevalence of serious accidents (PR= 0.76; 95%CI 0.6-2.94). Conclusion: The epidemiological profile indicated that the majority of bites occurred before 5pm, with care after 1am, and bites to the lower limbs were associated with a lower prevalence. The clinical profile was related to ICU admission and the use of vasoactive amines. Given the importance of scorpionism in children, it is crucial to educate the population in order to prevent accidents and improve prognosis.

Published: May 2024

Background. Wide local excision with sentinel lymph node biopsy has been the standard of care for melanoma with a Breslow depth greater than 1 mm. Wide local excision with 1- to 2-cm margins can result in large wounds that cannot be primarily closed. Traditionally, management has included reconstruction with autologous flaps and skin grafting. Case Report. The authors of this case report achieved successful closure of a large posterior calf wound after 2-cm–wide local excision of the melanoma biopsy site in a 61-year-old male. The dermal lesion was a Clark level IV superficial spreading malignant melanoma with Breslow depth of 1.1 mm. Wound closure was achieved with a DTS adhesive skin closure device coupled with MTP xenograft powder as a healing adjunct. Conclusion. The results of this patient's case indicate that DTS adhesive skin closure device should be considered as an additional option for the closure of large defects following wide local excision in the management of melanoma.

In the absence of GI symptoms, the histopathologic and clinical features of CCD can present as a variety of inflammatory skin conditions that can range from ruptured follicle-associated granulomas to cutaneous ulcerations. While a variety of therapeutic options for patients with CCD and concurrent luminal CD have been described in the literature, there is no standard treatment algorithm for the management of refractory CCD with limited or covert GI involvement. Case Report. The authors discuss the case of a 33-year-old female who presented to the wound care clinic with multiple "knife-edged" cutaneous ulcerations involving the intertriginous spaces, found to be consistent with CCD. Her original cutaneous symptoms and diagnosis manifested with minimal GI involvement and responded to IVIG treatment. Conclusions. This case supports the inclusion of CCD in the differential diagnosis in patients with knife-edged granulomatous skin lesions in intertriginous locations. This clinical condition may present in the setting of no or limited GI symptoms. The management of CCD and a proposed treatment algorithm are also presented.

Background. Changes in electrocardiographic parameters of the heart, reflecting the processes of depolarization and repolarization of the myocardium, can be signs of early cardiotoxicity (CT). Aim. To study changes in electrocardiographic parameters of the myocardium in patients with verified breast cancer 12 months after the end of chemotherapy with doxorubicin. Material and methods. The study included 100 patients with a confirmed diagnosis of breast cancer who were treated at the health care institution “Grodno University Clinic” (Grodno, Belarus). A number of electrocardiographic parameters of the myocardium were measured in patients before and 12 months after the end of chemotherapy using electrocardiography and 24-hour Holter monitoring. Results. A statistically significant increase in electrocardiographic parameters of depolarization and repolarization was revealed (P, P-Q, Tpeak-Tend, Q-Tc / QRS, Q-Tc - p<0.007; p<0.001; p=0.042; p=0.009; p<0.001, respectively) before and 12 months after the end of chemotherapy. A change in the time and total number of episodes of sinus tachycardia and supraventricular extrasystoles was also noted (p=0.029, p=0.026 and p=0.002). The Tpeak-Tend indicator changed statistically significantly in the CT+ subgroup (p=0.032) after 12 months. The dynamics of the Q-Tc indicator before and 12 months after the end of chemotherapy was observed in almost all patients. However, in the CT+ subgroup, an increase in Q-Tc was recorded statistically significantly more often compared to the CT- subgroup (p <0.005). Conclusion. During chemotherapy with doxorubicin, an increase in Tpeak-Tend and Q-Tc was observed. An especially significant increase in these indicators was noted in the CT+ subgroup. The number and duration of sinus tachycardia episodes as well as the number of supraventricular extrasystoles also increased. This may correlate with the relationship between chemotherapy with doxorubicin and the dynamics of electrocardiographic parameters.

Background. To carry out adequate antibacterial therapy directed against pathogenic microflora in patients with surgical infection it is necessary to take into account indicators of antibiotic resistance of leading etiological agents. The aim of the work is to study the spectrum and current dynamics of changes in antibiotic resistance of purulent pathogens in soft tissues of surgical patients. Material and methods. An analysis of the results of antibiotic resistance of the seeded leading microflora in patients with purulent processes of soft tissues was made. Results. Isolates of Staphylococcus aureus from surgical patients are characterized by high resistance to all β-lactam antibiotics, the combination drug trimethoprim-sulfamethoxazole, and macrolides. The resistance of Klebsiella pneumoniae and Proteus mirabilis to all studied β-lactam antibiotics, as well as fluoroquinolones, aminoglycosides, tetracyclines, nitrofurans, and chloramphenicol ranges from 37 to 100%. Escherichia coli resistance to β-lactams, fluoroquinolones, carbapenems, and aminoglycosides reaches 50-73%. A high level of antibacterial resistance is also characteristic of other bacteria most often cultured in surgical patients. Conclusions. The most frequently cultured strains of both gram-positive and gram-negative groups of microorganisms from surgical patients are characterized by a high level of antibacterial resistance, reaching 100%. Currently, cases of polyantibiotic resistance and resistance even to reserve antibiotics are not uncommon. All this dictates the need to search for new classes of substances that have an antimicrobial effect, and metal nanoparticles may be one of them.

Purpose. To identify the attitude and stereotypical perception of the population about the use of in vitro fertilization (IVF) in the Republic of Belarus. Material and methods. A sociological survey of a representative republican sample, which consisted of 1805 respondents (851 (47%) men, 954 (53%) women) aged 18 to 65 years, was performed. Results. In general, there is a positive attitude on the part of society towards reproductive technologies (21.6% of respondents claimed absolutely positive attitude and 30.2% had rather positive attitude to IVF; a neutral attitude was revealed in 37.1% of respondents). Some of the population retain stereotypes associated with varying degrees of influence of reproductive technologies on the psychophysical health of children (about 34%). Conclusion. A system of measures is needed to improve the preparation of married couples with an established diagnosis of infertility and the ineffectiveness of other treatment methods for artificial conception. This approach will minimize the number of failed IVF cycles and reduce the risk of complications for the mother and child. The effective use of assisted reproductive technologies (ART) with positive outcomes in overcoming infertility will contribute to the formation of a positive attitude towards reproductive technologies on the part of society.

Purpose. To analyze the aggregation function of platelets in patients with diabetic foot syndrome (DFS). Material and methods. Prospective clinical trial in which 31 patients participated have been conducted by us. To achieve this purpose, 2 groups have been formed: group 1 – patients with no history of diabetes (n=17); group 2 – patients with diabetes mellitus type 2 complicated by DFS (n=14). The studying of platelet aggregation was carried out once for first days after the admission of patients to the general somatic health care units, turbidimetric count method with an inductor: adenosine diphosphate (ADP) (concentrations of 0.3 mcg/ml, 0.6 mcg/ml, 1.25 mcg/ml and 2.5 mcg/ml were used), adrenaline (concentrations of 2.5 microns and 5.0 microns were used), collagen – 2 mg/ml. Results. In group 2 patients, the average platelet aggregation time, as well as in group 1, was lower than the reference values with an ADP inducer at a dose of 0.6 mcg/ml, 1.25 and 2.5 mcg/ml, and higher with adrenaline at a dose of 2.5 microns and with adrenaline at a dose of 5.0 microns. The degree of aggregation was lower than normal when used with all inducers except ADP 0.3 mcg/ml (normal), and the average platelet aggregation rate was lower with adrenaline. With the other inducers, platelet aggregation parameters were within the reference values. When adding inducers with all platelet aggregation parameters, significant differences were obtained between the two groups (p<0.05), and only when using ADP at doses of 0.6 mcg/ml, 1.25 mcg/ml and 2.5 mcg/ml, no significant differences were obtained for the aggregation rate parameter (p>0.05). Conclusion. In patients with DFS, compared with the people without diabetes mellitus type 2, the lowest degree of aggregation is noted with the use of ADP and adrenaline, the aggregation time is less with ADP, the aggregation rate is less with adrenaline and collagen 2 mg /ml. The degree of aggregation has increased with the use of collagen, and the aggregation time with adrenaline and collagen. The studying of platelet function is an important link in the laboratory control of spontaneous aggregation, which will limit the appearance of new vascular occlusions in patients with DFS.

Congenital malformations of the appendix are an extremely rare pathology, do not have a specific clinical picture and are usually detected at the time of surgery or pathohistological examination of the removed appendix. The purpose of the study. To present a description of a rare pathology – a case of incomplete doubling of the appendix and its atypical location, which contributed to the development of chronic recurrent appendicitis and periappendicitis. Results. The patient, aged 19, was operated on with a diagnosis of acute appendicitis. Laparoscopy has revealed that the appendix is partially retracted into the inguinal hernia and purulent fibrinous periappendicitis occurs. The vermiform appendix was removed. During its examination by both the surgeon and the pathologist, no developmental abnormality was detected. Pathohistological examination revealed incomplete doubling of the appendix. The additional process was located in the thickened mesentery of the main appendix. The complete absence of the outer layer in the muscle membrane and the serous membrane of the accessory process was revealed. This abnormality has provoked the development of chronic recurrent appendicitis and periappendicitis with the formation of an appendicular infiltrate. Conclusion. This article describes a rare clinical case of not only abnormal development of the appendix with the formation of chronic recurrent appendicitis, the formation of periappendicular infiltrate, but also its atypical location – it was partially involved in an inguinal hernia.
