Received: March 15th, 2023 ; Accepted: July 17th, 2023 ; Published: September 1st, 2023 ; Correspondence: [email protected] use of traditional tillage technologies in short-rotational crop rotations increases the cost of agricultural production and has a negative impact on the environment. The research was aimed at establishing and improving the ways winter wheat yield increase in short-rotational crop rotations depending on the efficiency of the main tillage system and fertilizing on typical chernozems s in conditions of unstable moisture in the Forest Steppe of Ukraine. The research was conducted at the Department of Agrochemistry National Scientific Centre Institute of Agriculture of National Academy of Agricultural Scienses at the Panfil Research Station of the National Scientific Center Institute of Agriculture of the National Academy of Agrarian Sciences in a stationary technological experiment, on typical low-humus chernozem in 2 short rotation crop rotations with the following crops rotation: crop rotation 1 - winter rape (Brassica napus L.), winter wheat (Triticum aestivum L), grain maize (Zea mays), spring barley (Hordeum vulgare L); crop rotation 2 - soybean (Glycine max (L.) Merrill), winter wheat (Triticum aestivum L), sunflower (Helianthus annuus), spring barley (Hordeum vulgare L). The article presents the results of research in two short-rotation crop rotations with the placement of winter wheat (Triticum aestivum L) after winter rape (Brassica napus L.) and soybean (Glycine max (L.) Merrill) against the background of two tillage systems: ploughing (25–27 cm) and no-till (direct sowing). The impact of different methods of soil cultivation and fertilizing systems on the humus content and nutrient regime of typical chernozems in the agrocenosis of winter wheat was determined. It was established that in winter wheat, placed after winter rapeseed and soybeans, there is a tendency to increase the humus content under zero tillage up to 15% relative to the control (without fertilizers) and from 5–14% relative to moldboard tillage (25–27 cm ploughing). The most effective in nutrient accumulation was fertilizing system N(90)P2О5(90)K2О(90) applied after rape and after soybean. Respectively, the content of mobile phosphorus compounds increased by 10–18% and potassium by 1.3–2.0 times compared to the control (without fertilizers) with the advantage of no-tillcultivation technology. The given comparative assessment of the yield formation of winter wheat when growing it after different pre-crops showed that the average yield of winter wheat grain in both cultivations on the control option for the soybean pre-crop was 3.55 t ha-1 and 4.00 t ha-1 for rape. The highest increases in grain yield on average over the years of research were provided by the fertilizing system of 50–54% (N(90)P2О5(90)K2О(90)) for growing winter wheat after soybeans and 39–47% (N(90)P2О5(90) K2О(90)) on the winter rape pre-crop with the advantage of moldboard tillage (ploughing) in crop cultivation technologies. The fertilizing system with the introduction of N(16)P2О(16)K2О(16) has the prospect of spreading because, in terms of the formation of typical indicators of chernozem fertility and the yield of winter wheat grain, it approaches technologies with the introduction of N(120)P2О5(90–60)K2О(100–90) with significant cost savings for mineral fertilizers

The vertex coordinates of the Galaxy's stellar systems according to the Gaia DR3 catalogue

We present the results of determining the coordinates of the vertices of various stellar systems, the centroids of which are located in the Galactic plane. To do this, the positions, parallaxes, proper motions, and radial velocities of red giants and subgiants contained in the $Gaia$~DR3 catalogue have been used. When determining the components of the deformation velocity tensors in local coordinate systems, we found the coordinates of the vertices of the stellar systems under study. It turned out that there is a complex dependence of vertex deviations $l_{xy}$ in Galactocentric cylindrical ($R, \theta$) and Galactic rectangular ($X,Y$) coordinates. Based on the approach proposed in this paper, heliocentric distances to vertices have been determined for the first time. The results obtained show that in addition to the fact that the angular coordinates of the Galactic center and the vertices of stellar systems do not coincide, their heliocentric distances do not coincide as well. This presumably indicates that there are structures in the Galaxy that noticeably affect its axisymmetry.Comment: 10 pages, 14 figures, 1 table

Endonasal orbitotomy as a first treatment for posttraumatic intraorbital hemorrhages in patients with frontal basilar trauma

Background: Intraorbital hemorrhages are one of the most dangerous complications of frontal bone trauma and frontal and orbital trauma because of the close and intricate anatomical relationships among the cranial cavity, orbit, nose and paranasal sinuses. Failure to solve the problem promptly will inevitably lead to disability. Effective treatment requires a multidisciplinary surgical team including a neurosurgeon, otorhinolaryngologist, ophthalmologist and a maxillofacial surgeon. Purpose: To assess the efficacy of endonasal endoscopic transethmoidal orbitotomy (TEO) and transcutaneous orbitotomy (TCO) in patients with post-traumatic intraorbital hemorrhages. Material and Methods: Fifteen patients (9 men and 6 women) with retrobulbar hematoma were included in this study. Patient age ranged from 33 years to 65 years. Of the 15 patients, 8 received endonasal endoscopic TEO and 7, TCO. Preoperatively, each patient underwent an eye examination, ultrasonography of the orbit, and spiral computed tomography of the paranasal and periorbital sinuses. Postoperative examinations were performed at 7 days and 1 month. Exophthalmos was assessed using a Hertel’s exophthalmosmeter (ALMAS YZ9). Sivtsev-Golovin charts were used to assess visual acuity. Statistical analyses were conducted using Microsoft Excel and Statistica (StatSoft, Tulsa, OK, USA) software. Results: The preoperative exophthalmos was 18.5 ± 2.12 mm in patients scheduled for TEO and 16.9 ± 1.78 mm in those scheduled for TCO. On day 7 after surgery (the day of discharge), exophthalmos reduced to 6.4 ± 0.77 mm in patients undergoing TEO (p < 0.0005) and 8.8 ± 0.94 mm in those undergoing TCO (p < 0.005). The preoperative visual acuity (VA) was 0.07 ± 0.03 in patients scheduled for TEO and 0.09 ± 0.05 mm in those scheduled for TCO. On day 7, mean VA improved to 0.81 ± 0.12 (p < 0.00005) in patients undergoing TEO, and to 0.56 ± 0.34 in those undergoing TCO. The two groups showed practically the same pattern of a longitudinal decrease in chemosis. Diplopia in upward and downward gaze and any restriction in ocular motility disappeared in patients undergoing TEO by the day of discharge (day 7), which was 4-5 days earlier than in patients undergoing TCO, with a postoperative period 4.25 ± 0.75 days longer (p<0.05) in the latter patients. At one month, mean VA improved to 0.89 ± 0.08 (p < 0.00005) in patients of the TEO group, and to 0.75 ± 0.15 (p < 0.005) in patients of the TCO group. Conclusion: Endonasal endoscopic transethmoidal orbitotomy was significantly more advantageous than transcutaneous orbitotomy, with a faster recovery, particularly, shorter postoperative period, faster restoration of visual acuity and ocular motility, minimum trauma to soft orbital tissues, and no external damage to facial skin

Крос-культурний дискурс філологічних студій: новітні підходи

The academic paper is devoted to exploring the newest approaches within the cross-cultural discourse of philological studies. The cross-cultural approach as a scientific basis for linguistic and literary studies emerged in the 30 s of the last century as a counterweight to ethnocentric studies; however, the boundaries of this discourse have now been significantly expanded and modified. Cross-cultural studies are less and less opposed to ethnocentric studies of national literatures and more and more tend to cross-cultural comparison. The primary purpose of the present academic paper is to analyze the methodological fundamentals and latest approaches of cross-cultural discourse in the system of philological studies, in particular, in the fields of linguistics, literary studies, translation studies, intercultural communication theory and linguoculturology. The semantic field of the concepts of “cross-cultural discourse”, “cross-cultural literary discourse”, “cross-cultural literature” and “cross-cultural research” has been outlined. The following newer approaches are distinguished in the cross-cultural discourse: comparative, anthropological, communicative, hermeneutical, which focuses on deciphering cultural codes, and conceptual. It is determined that cross-cultural interpenetration is most often observed in bilingual authors’ works. The researchers consider their texts as a synthesis of heterogeneous cultural elements, which results in a new multicultural artistic space that requires special tools for analysis.Стаття присвячена дослідженню новітніх підходів у крос-культурному дискурсі філологічних студій. Крос-культурний підхід як наукова основа лінгвістичних і літературознавчих студій виник у 30-х роках минулого століття на противагу етноцентричним студіям, однак межі цього дискурсу нині значно розширилися і модифікувалися. Крос-культурні студії все менше протиставляються етноцентричним дослідженням національних літератур і все більше тяжіють до міжкультурних порівнянь. Основною метою цієї статті є аналіз методологічних засад і новітніх підходів до вивчення крос-культурного дискурсу в системі філологічних досліджень, зокрема, в галузі лінгвістики, літературознавства, перекладознавства, теорії міжкультурної комунікації та лінгвокультурології. Окреслено семантичне поле понять «крос-культурний дискурс», «крос-культурний літературний дискурс», «крос-культурна література» та «крос-культурні дослідження». У крос-культурному дискурсі виокремлено такі підходи: компаративний, антропологічний, комунікативний, герменевтичний, який зосереджується на розшифровці культурних кодів, і концептуальний. Визначено, що крос-культурне взаємопроникнення найчастіше спостерігається у творах двомовних авторів. Дослідники розглядають їхні тексти як синтез гетерогенних культурних елементів, у результаті якого виникає новий мультикультурний художній простір

Human cardiac pericytes are susceptible to SARS-CoV-2 infection

COVID-19 is associated with serious cardiovascular complications, with incompletely understood mechanism(s). Pericytes have key functions in supporting endothelial cells and maintaining vascular integrity. We demonstrate that human cardiac pericytes are permissive to SARS-CoV-2 infection in organotypic slice and primary cell cultures. Viral entry into pericytes is mediated by endosomal proteases, and infection leads to up-regulation of inflammatory markers, vasoactive mediators, and nuclear factor kappa-B-dependent cell death. Furthermore, we present evidence of cardiac pericyte infection in COVID-19 myocarditis patients. These data demonstrate that human cardiac pericytes are susceptible to SARS-CoV-2 infection and suggest a role for pericyte infection in COVID-19

Distance learning: opportunities and challenges in quarantine.

The urgent introduction of distance education into the learning process due to the COVID-19 pandemic has become a spontaneous experiment, requiring urgent decisions, effective mechanisms to implement into the educational process and analysis of ongoing educational process. The possibilities of modern digital technologies made it possible to quickly set up the information component of education and to controle student’s knowledge. A detailed analysis of the communication between the faculty members of the department among themselves and analysis of the features of teaching and self-education of students in the field of medical radiology and oncology based on answers and comments with using Google classroom, Socrative, Messenger Telegram, etc. was made. Issues of communicative interaction between faculty members and students, psychological aspects of distance communication, language of instruction, logistics of distance education and methodological problems are described in details. It has been suggested that distance education may be equally effective for theoretical subjects in full-time study form, but when studying clinical disciplines, the priority should be given to traditional methods of teaching, involving student's bedside training. Taking into account technical possibilities and high risk of development of extreme and emergency situations, it is suggested to introduce permanent readiness for distance education, to create all – Ukrainian distance imitation service of patients’ follow-up. The importance of using the state language in training as the basis for mastering the professional Ukrainian and English language as the basis for mastering international medical experience is indicated

Семіотика українського та англійського інтелектуальних романів в контексті “людина-товар”

The article under consideration is devoted to the actual topic in modern society, which is investigated through the scope of Ukrainian and English intellectual novels “Misto” by V. Pidmohylnyi and “The Picture of Dorian Gray” by O. Wilde. This topic reveals the principle that life is a fair”, i.e. everything could be bought and sold, and a man is a commodity in this cruel world. The novelty of the research is that it is the first time an attempt to identify and explore the artistic-semiotic model of “life is a fair” in the works by O. Wilde and V. Pidmohylnyi in the perspective of modern comparative literature; the artistic-semiotic model of &quot;life-fair&quot; in a number of works of Ukrainian and English literature is systematically considered; the functioning of the model at the poetic and semiotic levels is comprehensively analyzed; the main structural elements of the literary model (constant and transient) are highlighted; a comparative-typological comparison of the creative work of writers was made, as well as the role and significance of a complex artistic-semiotic analysis of a literary work were specified. Further development of certain provisions of the research in future literary studies is likely on the basis of not only comparative but also theoretical vectors, which will be based on a more detailed study of the artistic and semiotic space of each of the studied artists. This will create an opportunity to identify complex artistic and semiotic paradigms of modeling the brightest representatives of domestic and world literature
