Authors:   Krasnoyarsk State Agrarian University, Arzumanyan Misak
Published: April 2023

The study reflects the principles and approaches to assessing the effectiveness of the activities of local authorities of municipalities of the second level in the Volgograd region, the most important tool for quantifying the well-being, standard of living of the population, aggregated in the form of the author’s methodology. The potential to achieve the values of performance indicators quantifies the degree of feasibility of the planned, expected values of the indicators of the municipality, interpreted as the ratio of “resistances” in relation to the achievement of the planned goals. The mechanism of the application of tools for converting the values of performance indicators is presented: coefficients (growth, achievement and resistance), potential, elements, integral values (and their degree of stability) of achievement. The achieved level of performance is analyzed. The application of the methodology provided information for the development of management decisions for the future: a high degree of stability is not observed in any of the municipalities; an average degree of stability is achieved in seven, and a moderate degree of stability is achieved in 24 municipalities; the remaining seven of the 38 municipalities have a low degree of stability. The most stable (effectively managed by local self-government bodies) municipalities of the Volgograd region are: Oktyabrsky, Chernyshkovsky, Novoanninsky, Surovikinsky; the least stable are Olkhovsky, Uryupinsky municipal districts.
The Impact of Urbanization on Living Standards of the Population in Russia
Authors:   LLC International Business Consulting Group, Mitroshin Igor
Published: April 2023

Urbanization has a significant impact on the development of human civilization. At the same time, the way civilization develops generates urbanization. The growth of large million-plus cities is changing the quality and style of life of an individual, family, household, as well as society, region and country. Large urban formations in modern conditions are both a consequence and indicator of the development of a country and the engine of its economic development. The greater the number and size of urban agglomerations and the faster their growth, the faster economic growth occurs. Under the conditions of urbanization, the structure of household incomes and expenditures, average wage and other factors affecting the standard of living of the population are changing. The purpose of this study is to analyze the relationship between individual aspects of the standard of living of the population in large cities of Russia. In particular, the dependence of the average wage and the purchasing power of the population on the size of the city’s population is considered. The article provides a more detailed analysis of the purchasing power of the population in the 15 largest cities of Russia and the degree of its dependence on the size of the city, as well as its growth rate. The relationship of urbanization with other factors affecting the standard of living of the population during the period of constant reform of the country’s economy has been studied. The analysis carried out is the basis for further forecasting of changes in the standard of living of the population and other aspects that affect household finances. The findings of the study make it possible to understand in general the main changes in the standard of living of the population in the conditions of urbanization, and sometimes deurbanization. The study was carried out on the basis of official statistical data of Rosstat, analysis of materials and works of other authors carrying out scientific activities in this direction.

Authors:   Vyatka State University, Kolesnikova Olga , Kozlova Elena ,   Vyatka State Agrotechnological University
Published: April 2023

The article is devoted to the problem of linguo-axiological research into modern leaders' value picture of the world, broadcasted to the youth audience in the emotiogenic discourse. The study is aimed at identification and analysis of the emotional representation of the axiological component in the texts of the discursive personality of the leader, who is thought as an influential and socially recognized person. The video recording of the student discussion clubs "Dialogue on Equal Terms" provided the material for the study. In line with the cognitive and discursive methodology based on recognition of axiological parameters of discourse determining cognition, the authors identified the value components of leadership in their emotiogenic representation, verbalized in talk shows as "secrets of success." The use of the linguo-axiological analysis of about 500 facts made it possible to identify speech tools for creating an emotiogenic utterance: the discursive genres "Advice" and "Suggestion", as well as an indirect way of "instructing young people" in a narrative form with adherent emotivity. With the help of axiosphere modeling, dominant and peripheral conceptual signs of leadership are established. The analysis of the frame composition of values objectified in the emotiogenic discourse as components of the personal system of leaders and group consciousness (leadership) testifies its purposeful creation for the translation of the value orientations of the subject of the discourse of youth.
Emotive Pragmatics of Popularisation Discourse: The Impact of Contextualisation on Reader’s Interest
Authors:   Herzen University, Trushchelev Pavel
Published: April 2023

The paper adheres to the pragmatic approach to emotion processes and focuses on emotion-evocative communication. Its goal is to investigate the impact of contextualisation techniques, which employed by popularisation discourse to induce readers' interest. The research is carried out in two ways, discourse-pragmatic and experimental. First, by adopting the sociopragmatic view of emotions and using methods of discourse analysis, the paper fleshes out a model of emotion-evocative communication, outlines contextualisation techniques, and introduces text materials. Second, by representing the experimental study, the paper assesses the interest-evoking effect of contextualisation. The experimental study involved 400 undergraduate students. We employed the scaling method (7-point bipolar scales) to measure participants' attitude to generalised and contextualised text passages. The data analysis applied the Wilcoxon test, the Kolmogorov – Smirnov test, Spearman's correlation coefficient, the linear regression, and the explanatory factor analysis. The comparing tests reveal that contextualisation promotes reader's interest in the popularisation text. The findings suggest that contextualisation techniques make the text content more relevant to the reader. Personal relevance – as a kind of mediator – causes interest responses. Beyond that, it was found that that reader's expectations about text strategies to presents knowledge construct interest-evocative communication. The findings demonstrate how communicative variables combine into the model of emotion-evocative communication.
On the Existence and Uniqueness of a Positive Solution to a Boundary Value Problem for a Nonlinear Second Order Differential Equation with Integral Boundary Conditions
Authors:   Dagestan State University, Abduragimov Gusen
Published: April 2023

In this Problems of the type presented in this article describe the operation of a harmonic oscillator under the influence of external forces, which is fixed in the extreme left position and has some mechanism at right one, that controls the displacement according to the feedback from devices measuring the displacements along parts of the oscillator. Above in the introduction, references are given to some papers in which integral boundary conditions for differential equations were considered. The paper is organized as follows: the boundary value problem considered in the paper is reduced to an equivalent integral equation, and the existence of a positive solution of the integral equation is established using the fixed point principle of an operator defined on a certain cone. An a priori estimate of such a solution is obtained, which subsequently participates in the proof of the uniqueness of a positive solution. Sufficient conditions for uniqueness follow from the uniqueness principle for u0 convex operators on a cone. At the end of the work, an example is given that demonstrates the results obtained.

The transport of suspended microplastic particles in an aqueous medium is closely related to hydrodynamic circulation. There are several mechanisms of horizontal and vertical movement of suspended microplastic particles associated with their concentration. In the article, a model describing the change in the concentration of suspended microplastic particles is considered, discretization is carried out, and the results of numerical experiments in two-dimensional and three-dimensional cases are obtained. The results of both the analytical model and numerical simulation demonstrate that waves can affect the distribution of floating particles near a free surface. The results of numerical simulation are largely consistent with the theory.

Authors:   Institute of High–Temperature Electrochemistry UB RAS, Zakiryanov D.
Published: April 2023

In vitro and in silico studies should supplement each other in order to obtain reliable and comprehensive data on physicochemical properties of molten salts. To attain the aim, the appropriate simulation technique is needed. Because of the computational speed that classical molecular dynamics could deliver, this method is often the most suitable for calculation of the transport properties. The accuracy of calculation is to a high degree depending on parameters of the potential. In this paper, we review the basics of the pair potential fitting procedure. As an example, a molten lithium chloride is considered. The comparison of different pair potentials in terms of potential energy and per-atomic forces is performed, with the reference data were obtained by means of the density functional theory. Among the macroscopic properties, the melting temperature and viscosity are calculated.

This article examines the relationship between the level of development of resistance to psychophysiological stress and elective martial arts classes among students of the Northern State Medical University. The authors analyzed the essence and structure of adaptation mechanisms to stressful situations, as well as the role of resistance to stress during the learning process. The purpose of the study is: to evaluate the effectiveness of martial arts classes in comparison with physical education classes. The study was conducted in the form of a survey among two groups of students of the Northern State Medical University: those who regularly attended elective martial arts classes, and a control group (students attending regular physical education classes). In total, 64 students of the 3rd and 4th courses of medical and pediatric faculties aged from 20 to 22 years took part in the study. To conduct a survey among students, the Lemur-Tessier-Fillion "Psychological Stress Scale" (PSM-25) was used, which helps to assess stressful feelings by various indicators. As the results of the survey presented in the article showed, students who engage in martial arts on a regular basis have low and medium levels of stress, whereas students of the control group are more characterized by a high level.

Hats off to Prometheus, who stole fire from heaven. From fire to WebGL, it's a long journey. But in today's world, WebGL is said to be the world's greatest invention. This paper is on the inquiry of the Web3D visualization methods in WEB. Three. js is a perfect 3D graphics engine out
of many We- bGL frameworks that has a lot ofbuiltin lights and materials. Meanwhile, it provides many convenient functions for this study. In addition, this research can be applied to the customization of LED lights and lanterns, interior de- sign, etc. This article introduces a kind of Web3D
technology along with Unity 3D engine, that combines great advantages in GPU acceleration in fields of game designing and visual effects. The basic scene setup is a bit different from Three JS and Babylon JS because Unity has its own editor. All the basic things like creating a scene, adding
mesh and lights can be done directly from the editor without coding a single line. This is a very ba- sic Unity feature and anyone with a little experience with the program can easily do this by adding the necessary objects to the scene from the Unity menus. Unlike Three. JS and Babylon. JS,
Unity does not require the creation of a rendering loop, which is done automatically by the game engine.

Increasing epidemiological evidence suggests a bidirectional relationship between non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes, and that NAFLD may precede and/or promote the development of diabetes. This study aimed to investigate whether liver steatosis is associated with the incidence of diabetes in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The ELSA-Brasil is an occupational cohort study of active or retired civil servants, aged 35-74 years, in six capital cities in Brazil. We excluded participants with diabetes at baseline, those who reported excessive alcohol consumption or with missing information on relevant covariates, and those with self-referred hepatitis or cirrhosis. In total, 8,166 individuals participated, and the mean duration of follow-up was 3.8 years. The Cox proportional regression model was used to estimate the adjusted hazard ratio (HR) for the associations. Abdominal ultrasonography was used to detect liver steatosis. In the follow-up period, the cumulative incidence of diabetes was 5.25% in the whole sample, 7.83% and 3.88% in the groups with and without hepatic steatosis, respectively (p < 0.001). Compared to those without steatosis, individuals with hepatic steatosis had an increased risk of developing diabetes (HR = 1.31; 95%CI: 1.09-1.56) after adjustment for potential confounders, including body mass index (BMI). Hepatic steatosis was an independent predictor of incident diabetes in the ELSA-Brasil cohort study. Physicians should encourage changes in lifestyle and screen for diabetes in patients with fatty liver.

Published: April 2023

RESUMO Este artigo pretende refletir sobre as grandes linhas que caracterizaram os processos de reforma da Administração Pública portuguesa entre 1967 (data da criação do primeiro organismo responsável por ela) e 1978 (data da criação do primeiro Ministério da Reforma Administrativa). Para tal, serão analisados debates parlamentares, legislação, documentação arquivística, programas de governo e alguns dos documentos mais relevantes dos primeiros tempos da Democracia. Argumenta-se que o processo de reforma administrativa apresentou continuidades entre os dois regimes, em termos institucionais, metodológicos e no que concerne aos seus objetivos. Defende-se que os seus pressupostos testemunharam, antes e depois da revolução, um processo contínuo de adaptação a diferentes conjunturas e desafios. Por fim, afirma-se que o período democrático permitiu um maior enquadramento institucional da reforma administrativa, na esteira da preparação do país para os desafios da época, a exemplo da integração europeia.
Between Antifascism and Antifa: A Conversation with Mark Bray, Author of Antifa
Authors: Schargel Sergio , Guimarães Julia de Oliveira Góes
Published: April 2023

ABSTRACT Antifa, by Mark Bray, innovated in a field of study with wide coverage: fascism. Bray dared to look at the other and forgotten side: anti-fascism. In his book Antifa: The Anti-Fascist Handbook, Bray deals not with anti-fascism as mere opposition to fascism, but with a tradition of political combat that dates back to the beginnings of Mussolini’s Fascism. It is noticeable in Antifa, and even in the interview that follows, the combination between the two universes of the author. Bray, an academic historian at Dartmouth College, analyzes historical and contemporary fascisms, as well as the evolution of the concept of fascism over the last century and the equally secular struggle of anti-fascists. But this is not just a book of academic or historiographical analysis. The militant side of the author (one of the organizers of Occupy Wall Street) emerges, especially in the dozens of interviews with anti-fascists around the world.

Abstract This study analyzes the strategies and challenges identified in the beginning of the Covid-19 pandemic to the provision of schooling for special education students, particularly from the perspective of public primary education teachers. The data were generated by means of the responses of 937 teachers from across Brazil to an online questionnaire that was posted on an accessible platform and translated into Libras. Among the results, it was observed that despite pre-pandemic investments on digital technologies, remote learning was predominantly carried out using printed material, and teaching special education students was pointed out as the main challenge. It is expected that this study will contribute to mapping the implications of remote learning for special education.
Men’s Perceptions of Domestic Violence Against Women: A Qualitative Study
Authors: Magrin Juliana Cristina , Oliveira Wanderlei Abadio de
Published: April 2023

Abstract Domestic violence against women is a serious social problem that requires male’s perspective understanding to be prevented. This study aimed to understand the perceptions of adult men, with higher education degree or higher education students, on this type of violence. Using Bandura’s social learning theory, a qualitative study was developed with 13 men. The data were collected using remote semi-structured interviews. The analytical process used thematic analysis presuppositions. It was found that men do not agree with sexist ideals that can increase the rates of violence against women. However, participants oscillate between understanding women as victim and as guilty. The data may be a reflection of the current greater debate on issues related to gender equality. We conclude that it is important to invest in the multidimensional training of men to break with hegemonic masculinity, which can foster the struggle against gender-based violence.

Regional Inequality in the Federal Budget Execution in Russian Regions
Authors:   Orenburg State University, Mokhnatkina L. B.
Published: April 2023

Federal budget expenditures in regions are not reduced to intergovernmental fiscal transfers to the budgets of the constituent entities of the Russian Federation. A significant part of the federal budget is spent directly in regions to support the expenditure commitments of the Russian Federation. The study aims to describe inter-territorial redistribution of financial resources and assess the contribution of the federal budget to regional per capita consumption by analysing data on 76 Russian constituent entities for 2016-2019. The article ranks regions according to the indicators of the federal budget per capita, estimates the ratio of federal and regional budgetary resources and tests the hypothesis about the impact of federal expenditures on regional per capita consumption. The following negative effects and trends were identified. Regions receive significantly less federal funds than the federal budget; the number of constituent entities with federal budget surplus increased. The regional inequality in terms of the federal budget execution indicators is growing: the gap between the maximum and minimum values of federal budget revenues per capita by region increased from 62 to 74 times; the gap between per capita expenditures is about 6 times. The disincentive effect of redistribution is strengthening due to increased withdrawals of income generated in donor regions and reduced spending of federal resources in recipient regions. Federal budget expenditures amplify the inequality in regional per capita consumption. Maximum and minimum specific values of the total federal and regional budget expenditures in regions differ by more than 10 times. The identified effects lead to an increase in regional inequality in the Russian Federation. According to the research results, intergovernmental redistribution mechanisms should be improved taking into account direct federal budget expenditures in regions.

This paper focuses on improving energy absorption through a series of heat treatment and quenching in medium, presence of nanoparticle. The characterisation of the experiment was to determine the suitable combination of composition factors: temperature, soaking time, and the medium that consist of nanoparticle on magnesium alloy surface structure to improve the energy absorption using quenching in nanofluids. The diameter and thickness of the specimen are 6 mm and 10 mm, respectively. All specimens undergo heat treatment based on the temperature of the furnace and the soaking time of the specimen in the furnace, which will be submerged into three medium distilled water, and the addition of a 0.1% wt carbon-nanotube (CNT) and 0.1% wt nano-silica. The addition of CNT and nano-silica shows an increment of 106.68%% and 59.30% for energy absorption, respectively, when compared to the controlled sample. Later microscopy has performed on the specimen to correlate the addition of nanoparticles in the heat treatment and improved energy absorption by EDS analysis on the material composition on the specimen’s surface. Therefore, this paper reveals factors of heat treatment and the presence of CNT and Nano silica effects on enhancing magnesium alloy energy absorption: UTS and yield strength using quenching method.

The usage of bollard is very important in protecting buildings. It can prevent vehicles from passing through the building. But the public now is less sensitive about the use of bollards. They assume the use of bollard is wasteful and for aesthetic only. Therefore, most buildings did not install bollards to protect the building. Besides that, there are also mounted bollards installed that are inappropriate to that place. For example, some bollards installed around buildings are not concrete type that can withstand strong impacts. Furthermore, some important and historic buildings need to install an explosive-proof type of bollard as building protection. The methods used for this research were non-destructive test and destructive test. Non-destructive test is slump test and destructive tests are compression test, tensile test, flexural test, and air blast test. Seven mix were used and tested in this research. From the compression test result, it shows that concrete mixed with 0.5% of macro synthetic is much stronger than control sample and other mixtures. From the tensile test, it shows that the control sample of the concrete achieved tensile strength of 3.48 N/mm2 while the mixed concrete with 0.5 % mix of macro synthetic fiber gave higher tensile strength. The flexural test shows that the concrete mixed with percentage ratio of 0.5%, 1.0%, and 1.5% of macro synthetic fiber gave higher strength than the control sample which is only 2.77 N/mm2. Based on experiments that have been carried out, it can fulfil objective one, which is to evaluate the type of blast safety for building envelope with the concrete bollard grade 30. Quality of concrete in terms of strength, tensile, and flexure of the proposed material with 0.5% of macro synthetic fiber can produce the same quality and meets the quality grade C30 concrete.

Traditionally, wind tunnel models are made of metal and the processes are very expensive. Since then, many researchers have been looking for new alternatives, hence 3D printing technology is the solution. Under right test conditions, 3D printed parts could be tested in a wind tunnel to get the aerodynamic performances. By using 3D printing technology, the cost and time can be significantly reduced to produce the wind tunnel models. This investigation was done to compare the aerodynamic performances which are drag and lift forces of the existing wind tunnel metal models with 3D printed wind tunnel models. Polylactic acid (PLA) was used as the printing materials by using two 3D printers which are Poseidon X and CR-10 S5. The wind tunnel testing covered the wind speed in the range of 0.57 m/s to 10.35 m/s at angle of-attack of 0°. Results from experiments show that the drag and lift forces of the 3D printed models show very close similarities with the metal models. It can be concluded that the wind tunnel models produced by using 3D printing technology can be used in wind tunnels for early testing.
ASSESSMENT OF THE GREEN AREAS CONDITION AS POTENTIAL OPPORTUNITIES TO PROVIDING ECOSYSTEM SERVICES
Authors:   Taras Shevchenko national University of Kyiv, Korohoda Nataliia
Published: April 2023

Manifestations of the environment to provide human needs with benefits arising from the healthy functioning of ecosystems are called ecosystem services (ES). Taking into account the large number of population – consumers of ES, which is concentrated in cities, green areas as the main providers of ES require significant attention. Accordingly to this, the objects of our study are the urban green areas (on the example of Kyiv). Despite the existing attempts to estimate ecosystem services in monetary terms, the cost of providing some of them (primarily regulating and cultural services) is almost impossible to estimate. In this case, attention should be focused on the condition and functions of ecosystems, and as a consequence – ES, which are different in each system, but provided in maximum volumes only in its sustainable functioning. After all, in a normal (stable) state, the ecosystem gives all its functions, and therefore provides its maximum benefits – ES. Therefore, the purpose of this work is to determine the urban green areas condition, as a prerequisite for their sustainable functioning as the potential possibility of providing ES by them. The study is based on the comparison of natural and actual vegetation cover of Kyiv. The parameters by which this correspondence is determined are the type of vegetation and the proportion of the green zone covered with typical (natural) vegetation. As a result of the work, based on remote sensing data, indicators of the state of individual green areas of the city were obtained, as well as averaged indicators for the city, individual administrative districts, etc. It is determined that the actual vegetation of green areas in Kyiv corresponds to the natural on 63.1 % of the green spaces area. Such condition is “close to natural”, according to Harrington’s desirability scale. However, such indicators differ significantly with administrative districts. They range from 34 % in Pecherskyi to 74 % in Sviatoshynskyi district. The example given in the paper demonstrates that even two neighboring green spaces can differ significantly in their condition, which, in particular, determines their opportunities to providing ES. These indicators will be very useful in further research on the overall assessment of ES, because, according to the general algorithm, it consists in determining 1. the condition of the green zone – potential opportunities in the provision of ES; 2. the efficiency of its functioning – the real volumes of ES provision; 3. the risks of ES loss. The results of this work are the implementation of the first component of the general algorithm and can be used in further research on the assessment of the real volumes of ecosystem services and the risks of their loss.

The research was carried out on the material of the Ukrainian Internet discourse, since nowadays it is an extensive source (it covers various electronic media, social networks, forums, blogs, chat rooms, guest books, search sites) and a powerful communicative environment, thanks to which the spheres of interpersonal and group communication have been enlarged enormously. That is why within it a significant amount of semantic neologisms are being created and productively functioning there. The main factors contributing to the activation of semantic processes in the modern Ukrainian language have been identified. It is characterized by neologisms that appeared due to the expansion of the semantic structure of a number of proper and borrowed words. The main thematic groups of well-known lexemes, represented by military, medical, sports, artistic and other topical fields, have been outlined and analyzed. Considerable attention is also paid to the creation of the non-codified new words through semantic derivation within the colloquial variantof language, and slang. It is characteristic that the vast majority of semantic neologisms recorded in modern Internet communication arise thanks to various metaphors that expand and enrich the expressive and figurative means of the Ukrainian language. Only some of neologisms appeared due to the shift of the meaning structure of the words based on metonymy and synecdoche. The main reasons for the active production of semantic neologisms in the Ukrainian Internet discourse are being analyzed.

Highlights. Stroke prevention in patients with atrial fibrillation is extremely important and difficult. Lifelong anticoagulant therapy is not always an effective way of preventing thrombosis in the left atrial appendage in this group of patients. In this regard, one of the most urgent problems of modern surgical arrhythmology and cardiac surgery is the search for new open and minimally invasive surgical methods of excluding the left atrial appendage from the blood flow.

Aim. To investigate the safety and efficacy of using the left atrial appendage stapler for video-guided thoracoscopic ablation (TSA) of non-valvular atrial fibrillation (AF).

Methods. The retrospective, single-center study included 100 patients with non-valvular AF who underwent video-guided thoracoscopic ablation of AF with single-stage left atrial appendage exclusion using an Endo GIA stapler (Medtronic, Minneapolis, Minnesota, USA).

Results. The mean age of the patients was 56,2±8,8 years, the majority of the patients (73 patients, 73%) were male. Patients with persistent 50 (50%) AF and longstanding AF 50 (50%) were included in the study. The duration of atrial fibrillation was 4 (1,7–7) years. The median CHA2DS2-VASc and HAS-BLED scores were 2 (1–1,5) and 1 (0-1), respectively. The mean anticoagulation therapy-to-ablation time was 4,2±1,9 years. Thirty-eight (38%) patients were prescribed warfarin preoperatively. The completeness of left atrial appendage (LAA) exclusion was confirmed by intraoperative transesophageal echocardiography. The average length of the staple lines was 48 (35–75). A single left atrial appendage exclusion was performed using a 60 mm staples. In 12 (12%) patients, stapler exclusions were performed using two 45 mm staples due to insufficient staple length. None of the patients had ruptures, punctures along the staple lines or rupture of the surrounding epicardial tissue. Anticoagulant therapy was discontinued 6 months after TSA in 70 (70%) patients with sustained sinus rhythm observed on 24-h Holter Monitoring, satisfactory CHA2DS2-VASc scores and after confirmation of absence of left atrial thrombus by transesophageal echocardiography and contrast-enhanced MSCT. No strokes were reported within 1,2±0,7 years after discontinuing anticoagulation therapy.

Conclusion. Exclusion of LAA using a stapler for TSA is a highly effective and safe technique for patients with non-valvular atrial fibrillation compared to alternative methods of excluding the LAA from the systemic blood flow.

Highlights. Ultrasound and MR venography of internal jugular veins in case of unilateral cerebellar hypoplasia or extrinsic stenosis enables noninvasively and without contrast agents differentiation of these conditions due to local and region-specific indicators, including the area and velocity of blood flow, arterial-venous balance, visualization of low blood flow, compression factor, and the overall clinical picture of venous network of the neck remodeling and the development of collateral circulation.

Aim. To compare the visual and hemodynamic characteristics of ultrasound and magnetic resonance venography of extrinsic stenosis and hypoplasia of internal jugular veins (IJV).

Methods. Ultrasound and magnetic resonance (MR) venography were performed in 47 patients with extrinsic stenosis and 23 patients with hypoplasia of one of internal jugular veins, and in the control group (30 patients).

Results. In case of obvious vein compression and deformation and local stenosis (65% on average), there is a decrease in the vein cross-sectional area by 2 times compared with the contralateral vein, the blood flow velocity in the stenotic vein in acute cases increases (on average, up to 45 cm/s), and in chronic cases it significantly (p = 0.00001) decreases (to 13 cm/s on average). The criteria for hypoplasia are the small caliber of the vein (on average 0.22 cm², within the range of 0.13–0.46 cm²) throughout its entire length - with the cross-sectional area not exceeding that of the common carotid artery, and the vein being 4 times smaller than IJV on contralateral side, as well as a significant (p = 0.0006) velocity increase on the contralateral side (on average 40.9±12.52 cm/s) with normal velocity in the hypoplastic vein. Ultrasound assessment of the arterial-venous balance (AVB) makes it possible to evaluate the contribution of each IJV to the outflow of venous blood from the brain separately. From the hypoplastic side it was only 11.01±6.72%, and from the stenotic side it was 18.22±17 42% on average, which is significantly (p = 0.000001) below the norm, but does not allow us to differentiate these conditions. The total AVB for IJVs on both sides was within normal values (65–85%), and the absence of a pronounced expansion of the vertebral veins during MR venography confirms their insignificant role in the compensatory mechanisms of ensuring adequate outflow of venous blood from the brain in cases of unilateral hypoplasia and extrinsic stenosis of IJV.

Conclusion. Ultrasound and MR venography of internal jugular veins in cases of unilateral hypoplasia or extrinsic stenosis enable noninvasively and without contrast agents differentiation of these conditions due to local and region-specific indicators, including the area and velocity of blood flow, arterial-venous balance, visualization of low blood flow, compression factor, and the overall clinical picture of venous network of the neck remodeling and the development of collateral circulation.
Semantic Annotator for Knowledge Graph Exploration : Pattern-Based NLP Technique

Published: April 2023

Semantic Annotator for knowledge Graph Exploration, abbreviated as SAGE is a “Thing” annotation system. Here, “Thing” refers to any concept, named individuals (aka entities), entity relations, and attributes. The system is primarily built based on the idea of “string to thing” where the “string” is any given text (e.g., abstract of an article) as input by the user. For annotation, the system utilises knowledge graph(s). SAGE can be used by anyone for annotating Things and for their exploitation on the Web. The annotation of things is done through exact and partial matches. For exact matches, the system makes explicit the name of the knowledge graphs it is sourced from. It also shows the type hierarchies for the matched named entities. In the current work, we describe the SAGE annotation system, designed on pattern-based NLP techniques, along with its features and various usage, and the experimental results.

The number of hip arthroscopies has rapidly increased worldwide due to the new knowledge of intraarticular hip pathology. This procedure is successful with a low rate of complications but severe. One of the most important, from the anesthetic point of view, is hypothermia, carrying out a physiological response that could be dangerous for the patients. In hip arthroscopies, a warmed irrigation solution has been implemented as a simple, low-cost, and effective method for preventing hypothermia. There is limited literature on hip arthroscopy; therefore, much of the literature is focused on shoulder and knee arthroscopy. This systematic review of the literature aims to analyze the current evidence of warmed irrigation solutions in hip, shoulder, and knee arthroscopy. This systematic review of the literature aims to analyze the current evidence of warmed irrigation solutions in hip, shoulder, and knee arthroscopy. Eight studies of patients undergoing arthroscopy were included in the qualitative synthesis (6 shoulder studies, 1 hip study, and 1 knee study; 526 patients). Warm irrigation fluid reduced the degree of core body temperature drop and the incidence of hypothermia in 6 studies (5 shoulder studies and 1 hip study). In conclusion, warming irrigation fluids for shoulder and hip arthroscopy significantly decreased the risk of hypothermia, increased the lowest mean temperature, decreased the maximum temperature drop, and decreased the risk of shivering and hypothermia.
