Place de l’hypnose dans le désapprentissage de la douleur de l’accouchement : une étude
Authors: Chalut-Natal Morin C. , Bioy A.
Published: May 2022

L'accouchement entretient des liens spécifiques avec la transe et les phénomènes de suggestion du fait des capacités d'hypnotisabilité de la femme enceinte. Cette recherche, innovante, teste un modèle de compréhension de la dynamique d'accompagnement des femmes enceintes jusqu'à l'accouchement. Le potentiel de l'hypnose comme processus de déconditionnement de la peur et de la douleur de l'accouchement est évalué. La méthodologie s'appuie sur l'analyse phénoménologique qualitative des entretiens de neuf femmes, complétée par des questionnaires d'évaluation de l'anxiété, de la douleur, du vécu de l'accouchement et une analyse du dossier obstétrical. Les résultats montrent qu'en anténatal, les processus d'anticipation, d'anxiété et de peur peuvent être réévalués grâce à la pratique de l'hypnose, durant laquelle la femme est systématiquement installée dans une situation émotionnelle positive ou neutre ou en situation de contrôle. Elle va alors réévaluer l'expérience de l'accouchement à venir de façon congruente avec les expériences qu'elle vit en transe hypnotique. À ce niveau, la suggestion est le véhicule du contre-conditionnement. Cette nouvelle évaluation peut être considérée comme un effet du conditionnement évaluatif, puisque ce changement est lié à la création d'une nouvelle relation établie au décours des séances d'hypnose. L'insuffisance de la pratique personnelle est un frein à l'efficacité de l'hypnose. Cette nouvelle évaluation n'est possible que si elle est ancrée par une pratique régulière de l'autohypnose. Ce changement d'évaluation s'appuie sur l'engagement du sujet dans le processus et procède d'un nouvel apprentissage, notamment quant à la façon d'envisager la douleur de l'accouchement et de la gérer.

Published: May 2022

Introduction: Cataract is the major cause of blindness and visual impairment. Although there are several reasons for the generation of cataract, however, most of the cases are due to inter-individual genetic variations in antioxidant genes. Many studies have been conducted for the understanding of the role of reactive oxygen species (ROS) in the regulation of cataract. However, the study of single nucleotide polymorphisms (SNP) of the Glutathione peroxidase gene and Catalase gene and its association with cataract is still lacking in the Pakistani population. Objective: To investigate the relationship between GPX and CAT gene variations and the development of Cataract in Pakistani cataract patients. Methods: This was a case-control study carried out at different centres in Karachi, Pakistan between September 2019 and 2020. A single nucleotide polymorphism (SNP) at rs1050450 for GPX and rs7943316locus for Catalase gene mutations was examined with polymerase chain reaction (PCR) using high resolution melting curve (HRM) technique in 250 cataract patients and 250 healthy control groups of similar age. Results: We detected the ratio of SNP in GPX gene in cataract patientsis higher than in control (OR: 1.8, 95% CI) while there is no significant difference in CAT gene between cataract and control participants. Conclusion: Our findings indicate potential genetic variations in antioxidant genes particularly GPX and CAT genes polymorphisms as risk factors for cataract. This is study the first studyto report the antioxidant SNPs associated with the developmentof cataract in the Pakistani population.

Published: May 2022

Introduction: Renal cell tumours are common neoplasms with varying incidence and mortality rates across the globe. There are many histological types forming not merely the basis of classification but being associated with unique immunological and molecular profiles governing the biological behaviour. Apart from these, there are separate spectrum of neoplasms restricted particularly to paediatric age group. The overall prognosis is conferred by an array of factors including the histological grade, stage, necrosis and lympho-vascular invasion. Case Reports: This discussion aims to outline the renal mass encountered in our setting with special reference to age group and the light microscopic picture. However, we encountered diagnostic dilemmas while dealing with the cases and these were further resolved employing relevant immunohistochemical markers. A particular mention of protocols for staging, grading and relevance of special stains has also been outlined. Conclusion: To conclude, 1 case each of chromophobic renal cell carcinoma and infiltrating urothelial carcinoma of pelvis in middle aged adults have been discussed. 2 cases in paediatric age group have been highlighted namely triphasic nephroblastoma and multicystic dysplastic kidney (MCDK).

Індивідуально-авторське словотворення в поезії Андрія Малишка
Authors: Віняр Г. М.
Published: May 2022

Проаналізовано індивідуально-авторське словотворення в поезії Андрія Малишка. У словотворенні поета знайшло відображення розмаїття іменникових суфіксів, часто деактивізованих у сучасній мові, що посилює художні, виражальні можливості їхніх похідних. Аналіз індивідуально-авторських новотворів у поезії Малишка засвідчує увагу автора до давніх українських словотвірних типів, що переважно вичерпали дериваційну базу і не виявляють активності в сучасній номінації. Проте незмінне чуття слова, пошук нових засобів виразності, знання автором глибинних шарів української лексики сприяли появі цілої низки похідних із експресивно-стилістичною функцією.

Published: May 2022

Проведены ab initio расчёты нового типа дефекта в материалах с ковалентными связями - ориентационного дефекта (ОД). ОД представляет собой типичное дефектное состояние в аморфном тетраэдрическом полупроводнике, в окрестности которого не происходит радикальной перестройки химических связей: последние испытывают лишь угловые и радиальные деформации. Существование ориентационных дефектов позволяет пересмотреть традиционные представления о метастабильных свойствах аморфных веществ и непротиворечиво интерпретировать широкий спектр особенностей их поведения как в условиях термодинамиче ского равновесия, так и в состоянии, далёком от равновесного (например, эффект Стеблера-Вронского). Кроме того, ОД можно рассматривать в качестве модели ангармонических межатомных потенциалов, обуславливающих низкотемпературные аномалии физических свойств неупорядоченных материалов. Некоторые из них впервые рассмотрены с новых позиций.

Peculiarities of using of the Moodle test tools in philosophy teaching
Authors: Abdula Andrii I. , Baluta Halyna A. , Kozachenko Nadiia P. , Kassim Darja A.
Published: May 2022

The paper considers the role of philosophy and philosophical disciplines as the means of forming general cultural competences, in particular, in the development of critical thinking. The article emphasizes that the process of forming over-subject and soft skills, which, as a rule, include also critical thinking, gets much more complicated under the conditions of the reduction in the volume of philosophical courses. The paper grounds that one of the ways to “return” philosophy to educational programmes can be the implementation of training, using the e-learning environment, especially Moodle. In addition, authors point to the expediency of using this system and, in general, e-learning as an instrument for collaborating students to the world’s educational community and for developing their lifelong learning skills. The article specifies the features of providing electronic support in philosophy teaching, to which the following belongs: the difficulty of parametrizing the learning outcomes; plurality of approaches; communicative philosophy. The paper highlights the types of activities that can be implemented by tools of Moodle. The use of the following Moodle test tasks is considered as an example: test control in the flipped class, control of work with primary sources, control of self-study, test implementation of interim thematic control. The authors conclude that the Moodle system can be used as a tools of online support for the philosophy course, but it is impossible to transfer to the virtual space all the study of this discipline, because it has a significant worldview load. Forms of training, directly related to communication, are integral part of the methodology of teaching philosophy as philosophy itself is discursive, dialogical, communicative and pluralistic. Nevertheless, taking into account features of the discipline, it is possible to provide not only the evaluation function of the test control, but also to realize a number of educational functions: updating the basic knowledge, memorization, activating the cognitive interest, developing the ability to reason and the simpler ones but not less important, – the skill of getting information and familiarization with it.

Published: May 2022

STEM-education is a modern effective approach that nowadays can be interpreted in very different ways and it even has some modification (STEM/STEAM/STREAM). Anyway, the “New Ukrainian school” concept includes approaches similar to STEM-education. However, there wasn’t analyzed the current state of STEM-education in Ukraine. We propose to analyses it by using SEO analysis of one of the most popular STEM-oriented cloud environment in Ukraine stemua.science. It is proposed to use the cycle for cloud-based educational environments (publishing/SEO analysis/team’s brainstorm/prediction/creation of further plan) to improve their efficiency. It is found, that STEM-based and traditional publications are characterized by similar demand of educational process stakeholders. However, the way how teachers and students found the publication proves that traditional keywords (47.99 %) used significantly more common than STEM keywords (2.67 %). Therefore, it is proved that STEM-methods are less in demand than traditional ones. However, considering the huge positive effect of the STEM method, stemua.science cloud educational environment provides a positive effect on the educational process by including the STEM-aspects during finding traditional approaches of education by stakeholders of the educational process.

Іван Огієнко про «новий ять» у тексті Крехівського Апостола
Authors: Вербовий М. В.
Published: May 2022

У статті проаналізовані іменники, подані І. Огієнком як приклади до фонетичного явища «нового ятя» в тексті Крехівського Апостола. Уважний розгляд особливостей складу іменників-ілюстрацій фонетичного явища, зіставлення цих номенів з назвами, що мають таку ж форму, але зафіксовані в тексті Крехівського Апостола зі збереженням старого голосного, залучення статистичних показників – все це дає підстави авторові статті свердити, що, найвірогідніше, справжнього «нового ятя» текст Крехівського Апостола не фіксує. Відповідно, номени-ілюстрації, використані І. Огієнком, передають лише графічне, а не фонетичне явище. Зроблений висновок змушує переглянути вже усталену думку Івана Огієнка про українську основу мови Крехівського Апостола.

Published: May 2022

Die Bewegungen und die kinematische Interpretation des Rutschungskomplexes von Brienz/Brinzauls (GR) sind Gegenstand detaillierter Untersuchungen. Sie liefern Grundlagen, um die Gefährdung des Dorfes zu beurteilen und entsprechende Massnahmen zu planen. Neben den klassischen Methoden Total Station (TPS), Global Navigation Satellite Systems (GNSS) und Inklinometer kommen auch terrestrische Radarinterferometrie und digitale Bildanalyse zum Einsatz. Dieser Artikel beschreibt neue Methoden der Integration Satelliten-basierter Radar-Interferometrie (DInSAR) und der digitalen Bildkorrelationsanalyse, die ein flächendeckendes Abbild des Verschiebungsverhaltens in drei Dimensionen generieren. In der Folge beschreiben wir die Stapelung differenzieller Interferogramme von C-, L- und X-Band-Radar-Satellitendaten sowie die Integration von Ergebnissen der Interferometrie mit digitaler Korrelation von hochaufgelösten optischen und Radarbildern der Jahre 2015 bis 2020. Auf der Basis dieser Resultate werden anschliessend verschiedene Verformungskomponenten des Rutschungskomplexes ermittelt, die für die Ermittlung von Rutschungskompartimenten und ihrer Kinematik wesentlich sind. Die Ergebnisse werden mit existierenden GNSS-Messdaten validiert.
Radarüberwachung von Massenbewegungen
Authors: Gassner Johannes , Wahlen Susanne , Meier Lorenz
Published: May 2022

In der Überwachung von Naturgefahren kommen generell Warnsysteme für langsame Bewegungen und Alarmsysteme für schnelle Bewegungen zum Einsatz. Radar hat sich dabei als geeignete Technologie etabliert, da damit aus mehreren Kilometern Entfernung grosse Gebiete abgedeckt werden können und die kontinuierliche Messung bei allen Sicht- und Wetterverhältnissen möglich ist. Mit dem interferometrischen Radar lassen sich millimetergenaue Deformationsanalysen erstellen, während das Dopplerradar die Echtzeiterkennung von Steinschlag oder Lawinen ermöglicht. Bei der Rutschung in Brienz/Brinzauls (GR) sind seit mehreren Jahren beide Radartypen erfolgreich im Einsatz; einerseits zur grossflächigen Überwachung der Rutschung und andererseits als Steinschlag-Alarmsystem mit automatischer Sperrung der Strasse nach Lenz. Die Überwachung von Rutschungen stellt besondere Anforderungen an die Auswertung von interferometrischen Radarmessungen. Deshalb hat Geopraevent ein spezielles Analysemodell entwickelt, das Störeinflüsse herausfiltert, die durch turbulente atmosphärische Bedingungen verursacht werden.

Comparative analysis of different Guanche populations of Tenerife: a preliminary and short review
Authors: Rodríguez-Martín Conrado , Rosario-Adrián M. Candelaria , Benito-Mateo Carmen , Del-Arco-Aguilar M. Mercedes , Martín-Rodríguez Alberto Jesús
Published: May 2022

Along the 19th and 20th centuries the Guanche population of Tenerife (around the C.E. - 1496) was observed as a whole, without chronological and geographic differences. Since the so-called “Cronos Project. Bioanthropology of Guanche mummies” (concluded in 1992) new perspectives in archaeological and bioanthropological research were introduced demonstrating that the Guanche prototype did not exist and, on the contrary, the different pre-Hispanic populations of the island suffered a long period of adaptation depending of the area in where they lived.There was no a Guanche, but many. This paper is a brief summary of the differences observed in several populations according to different parameters.
Sexual differences in several skeletal occupational markers in the Guanche population of the northern slope of Tenerife
Authors: Martín-Rodríguez Alberto Jesús , Versace Giovanni
Published: May 2022

In 1998, in the locality of Mesa del Mar (municipality of Tacoronte, northern slope of the island of Tenerife, Canary Islands), a Guanche funerary site was digged up.This site, dated in the 10th century AD, was located in a cave, on the top of a coastal cliff, and was composed of the skeletal remains of a minimum of 36 individuals of both sexes.
An analysis of these remains, compared to other remains from two other sites of similar characteristics (Cueva de La Lana and Cueva del Guanche) seem to suggest, after analyzing the changes in the cervical vertebral bodies and the presence of occupational stress markers in clavicles and scapulae, the presence of intersexual differences compatible with differences in the type of work performed by the aboriginal population.

Ambas publicaciones, escritas en latín, han sido objeto de controversia en últimos años sobre la cuestión de si los nuevos nombres de especies publicados por Sventenius cumplen o no con las normas del Código Internacional de Nomenclatura Botánica, que es el marco jurídico internacional que rige los nombres científicos de las plantas. Aquí se argumenta que los nombres de Sventenius están publicados válidamente y deben ser aceptados como tales.
On Local Antimagic Vertex Coloring for Complete Full t-ary Trees
Authors: Bača Martin , Semaničová-Feňovčíková Andrea , Lai Ruei-Ting , Wang Tao-Ming
Published: May 2022

Let G = ( V, E) be a finite simple undirected graph without K2 components. A bijection f : E → {1, 2, ⋯, | E|} is called a local antimagic labeling if for any two adjacent vertices u and v, they have different vertex sums, i.e., w( u) ≠ w( v), where the vertex sum w( u) = ∑ e∈ E( u) f( e), and E( u) is the set of edges incident to u. Thus any local antimagic labeling induces a proper vertex coloring of G where the vertex v is assigned the color (vertex sum) w( v). The local antimagic chromatic number χla( G) is the minimum number of colors taken over all colorings induced by local antimagic labelings of G. It was conjectured [6] that for every tree T the local antimagic chromatic number l + 1 ≤ χla( T) ≤ l + 2, where l is the number of leaves of T. In this article we verify the above conjecture for complete full t-ary trees, for t ≥ 2. A complete full t-ary tree is a rooted tree in which all nodes have exactly t children except leaves and every leaf is of the same depth. In particular we obtain that the exact value for the local antimagic chromatic number of all complete full t-ary trees is l + 1 for odd t.
Getting There and Back Again
Authors: Danvy Olivier
Published: May 2022

“There and Back Again” (TABA) is a programming pattern where the recursive calls traverse one data structure and the subsequent returns traverse another. This article presents new TABA examples, refines existing ones, and formalizes both their control flow and their data flow using the Coq Proof Assistant. Each formalization mechanizes a pen-and-paper proof, thus making it easier to “get” TABA. In addition, this article identifies and illustrates a tail-recursive variant of TABA, There and Forth Again (TAFA) that does not come back but goes forth instead with more tail calls.
On the 2-domination Number of Cylinders with Small Cycles
Authors: Garzón Ester M. , Martínez José A. , Moreno Juan J. , Puertas María L.
Published: May 2022

Domination-type parameters are difficult to manage in Cartesian product graphs and there is usually no general relationship between the parameter in both factors and in the product graph. This is the situation of the domination number, the Roman domination number or the 2-domination number, among others. Contrary to what happens with the domination number and the Roman domination number, the 2-domination number remains unknown in cylinders, that is, the Cartesian product of a cycle and a path and in this paper, we will compute this parameter in the cylinders with small cycles. We will develop two algorithms involving the (min, +) matrix product that will allow us to compute the desired values of γ2( Cn□ Pm), with 3 ≤ n ≤ 15 and m ≤ 2. We will also pose a conjecture about the general formula for the 2-domination number in this graph class.
Cerebrospinal Fluid Biomarkers for Cerebral Amyloid Angiopathy Diagnosis
Authors: Charidimou Andreas
Published: May 2022

An accurate diagnosis of sporadic cerebral amyloid angiopathy (CAA) is critical for patient management and research (including clinical trials) for this common small vessel pathology of the brain. While the “big bang” of the CAA field has been the device and wide adoption of the clinico-radiological Boston criteria which allowed for CAA diagnosis during life, these criteria are not without major shortcoming. As it is now becoming evident that CAA is probably not a single disease, but rather represents divergent pathophysiological phenotypes and clinical trajectories, new biomarker-driven diagnostic approaches should be sought. One such complimentary approach for CAA diagnosis is the use of cerebrospinal fluid biomarkers (CSF), which could provide dynamic measures of the underlying disease process and is discussed in this commentary given exciting new advances. A hint on how the practicing clinician could apply the current CSF data for CAA diagnosis is also provided.
Some aggregation operators of credibility trapezoidal fuzzy neutrosophic values and their decision-making application in the selection of slope design schemes
Authors: Ye Jun , Du Shigui , Yong Rui
Published: May 2022

Modern decision-making (DM) systems are becoming more and more complex and sophisticated in their demands for information expressions and credibility levels. In the existing literature, a trapezoidal fuzzy neutrosophic value (TFNV) that combines trapezoidal fuzzy numbers with neutrosophic values can be better depicted by truth, indeterminacy, and falsity membership functions. Unfortunately, TFNV implies its defect since it lacks a measure of credibility. To make TFNV more creditable, TFNV should be related to its credibility level. Regarding the motivation for combining TFNV with its credibility level, this paper first proposes the concept of a credibility TFNV (C-TFNV) as a new framework of TFNV associated with the measure of credibility. The advantage of its information expression is that C-TFNV has a more creditable ability to describe indeterminate and inconsistent knowledge and judgments of human beings by the mixed information of a TFNV and a related credibility level (an ordered pair of TFNVs). Next, we propose the operational laws of C-TFNVs and the score function of C-TFNV. Furthermore, we present a C-TFNV weighted arithmetic averaging (C-TFNVWAA) and a C-TFNV weighted geometric averaging (C-TFNVWGA) operators and their properties. Then, a multicriteria DM model based on the C-TFNVWAA and C-TFNVWGA operators and the score function is established in the case of C-TFNVs. Finally, an actual DM example of slope decision schemes is provided to show the applicability and efficiency of the established DM model in the case of C-TFNVs.

The rapid and effective identification of leaf diseases of woody fruit plants can help fruit farmers prevent and cure diseases in time to improve fruit quality and minimize economic losses, which is of great significance to fruit planting. In recent years, deep learning has shown its unique advantages in image recognition. This paper proposes a new type of network based on deep learning image recognition method to recognize leaf diseases of woody fruit plants. The network merges the output of the convolutional layer of ResNet101 and VGG19 to improve the feature extraction ability of the entire model. It uses the transfer learning method to partially load the trained network weights, reducing model training parameters and training time. In addition, an attention mechanism is added to improve the efficiency of network information acquisition. Meanwhile, dropout, L2 regularization, and LN are used to prevent over-fitting, accelerate convergence, and improve the network’s generalization ability. The experimental results show that the overall accuracy of woody fruit plant leaf diseases identification based on the model proposed in this paper is 86.41%. Compared with the classic ResNet101, the accuracy is improved by 1.71%, and the model parameters are reduced by 96.63%. Moreover, compared with the classic VGG19 network, the accuracy is improved by 2.08%, and the model parameters are reduced by 96.42%. After data set balancing, the overall identification accuracy of woody fruit plant leaf diseases based on the model proposed in this paper can reach 86.73%.

Authors: Priya D. Bhanu , Subramaniyam Murali
Published: May 2022

BACKGROUND: The easy accessibility of smartphones has led to a fivefold increase in their use. People use smartphones almost anywhere, including during travelling and studying. During the global COVID-19 pandemic, the average smartphone screen time has increased from 2.25 to 4.8 hours per day. In India, smartphone usage increased by 68%, and the average screen time increased from 2.42 to 6.9 hours. This dependency on smartphones has led to smartphone addiction. Inappropriate postures during the prolonged use of smartphones can exert adverse effects such as musculoskeletal disorders, digital eye strain, loss of focus and attention. OBJECTIVES: This study was undertaken to understand the effects of prolonged smartphone utilisation and explored fatigue measurement techniques. METHODS: A total of 130 studies examining the effects of smartphone utilisation published in the previous 10 years were identified from the following databases: IEEE, Science Direct, PubMed, PubMed Central, and Google Scholar are reviewed. This study was conducted from September 2019 to January 2021. RESULTS: One in every four adolescents were prone to smartphone addiction, which causes poor mental health. Moreover, India’s research on the effects of excessive smartphone usage is limited. CONCLUSIONS: Studies are required to establish the correlation between fatigue levels and smartphone usage patterns.

Published: May 2022

The article discusses the need to solve the problem of increasing the temperature limits of the operation of the cooling system of the internal combustion engine (ICE) of the helicopter. This issue arose from the fact that during the operation of the helicopter on the territory of African countries with a hot climate, the engine overheated. The use of helicopters in these conditions was due to the demand in the aviation market. To solve the problem, new elements of the cooling system were selected, i.e. radiator and two types of fans. The research was aimed at increasing the heat transfer from the radiators of the cooling system by increasing the size of the radiator and increasing the air flow rate through the radiator. 3D modeling, design of a new cooling system (CO), and then design of CO in two versions with TEMIC and SPAL fans were done. First, ground and flight tests for two prototypes in a temperate climate were done, as a result of which a prototype with the best performance parameters was determined. During the tests the equipment and measuring instruments were used: voltmeter, ammeter, voltmeter; shunt; motor tester with the ability to transfer data via Bluetooth; smartphone with OpenDiag software installed, which is included and connected to the motor tester via Bluetooth, helicopter objective control system, flight data registration system, equipment and devices normally installed on the helicopter. For flight tests in hot climates, a new cooling system with a SPAL fan was used, these tests lasted three days. This article describes the final stage of a series of tests for the effectiveness of the cooling system of a helicopter and an analysis of the results obtained with confirmation of the final achievement of the set goals, i.e. raising the upper temperature limit of the outside air for the safe operation of the helicopter.
Expert express assessment of the impact of heat and mass transfer processes on the residual life of the WWER-1000 reactor vessel due to cyclic damage

Published: May 2022

Ukraine remains a country dependent on nuclear energy for both heat supply and satellite supply. In cities close to nuclear power plants, electric heating from the electricity they produce is appropriate. On the other hand, Ukraine is the only country in the world where the worst accident at a nuclear power plant occurred at the Chernobyl NPP Unit 4 on the night of April 26, 1986. Another characteristic feature of Ukraine's nuclear energy is the significant number of power units with exhausted project resources - the so-called "old" power units. Their wear is associated with the influence of heat and mass transfer processes, which lead to periodic thermal deformation of the elements, which causes cyclic damage. An example of expert rapid assessment of the residual life of a specific reactor vessel WWER-1000 is given taking into account the combined action of non-stationary heat and mass transfer and mechanical processes. A detailed express calculation of cyclic (tired) damage to the metal of the WWER-1000 reactor vessel due to the dangerous emergency mode has been performed. The WWER-1000 reactor is the last most widespread and most powerful water-water nuclear reactor of the former USSR, operated on 13 of the 15 operating power units of Ukrainian nuclear power plants (NPPs) - Zaporizhia, Rivne, Khmelnytsky and South Ukraine (SUNPP). The reactor is the most important indispensable element of a nuclear power plant, which determines its safety and resource. Given the design resource and the dates of commissioning of Ukrainian NPP units, the issue of rapid expert assessment of the technical condition of WWER-1000 hulls is quite relevant. Of course, modern engineering has the full range of tools needed to perform such estimates, from powerful computers to advanced computing software. But the known and inevitable costs of modern engineering - complex and time-consuming modeling and calculations. Experience has shown that a certain "reasonable" combination of the use of relatively simplified "light" calculation methods allows us to assess the safety, strength and service life of WWER-1000 reactors very quickly and with the necessary accuracy acceptable for expert opinion. The publication considers as an example the real emergency situation of October 22, 1985 and the WWER-1000 reactor of SUNPP Unit 1. Since this emergency situation led to rapid cooling of this reactor, the calculation of the effect of cyclic damage of reactor steel on the strength and reliability of the reactor vessel is shown. This example and the consideration of the real emergency situation demonstrates the effectiveness and acceptability of the use of estimated expert rapid assessments to accurately determine the reliability and safety of such critical elements of nuclear power plants as nuclear reactor buildings.
Changes in the composition and quality of gas during its movement in the gas supply system
Authors: Franchuk Y.
Published: May 2022

Gas produced at different deposits has different compositions, namely different amounts of methane, propane, nitrogen and so on. Different gas composition determines different physical and chemical characteristics of the gas, its heat of combustion, dew points on water and hydrocarbons, and Wobbe number. Previously, when using gas, little attention was paid to its characteristics, which are guided by the requirements of GOST 5542-87. With the restoration of Ukraine's independence and the transition to market conditions, attitudes toward gas have changed. Gas is a commodity and has a price. With the integration into the European Union, there was not only the implementation of European legislation but also the widespread use of advanced equipment and technologies in these countries. Gas will be metered in units of energy, not volume as before. This forces us to pay more attention to the quality of gas, set stricter requirements for its component composition, and monitor compliance with regulatory requirements in the process of transporting and supplying gas to the final consumer. GOST 5542-87 defined only a few quality parameters. Currently, the Code of Gas Transmission and Gas Distribution Systems, the Technical Regulation of Natural Gas and other regulations determine the quality of gas by more than 20 parameters that meet European standards. The methane content in the composition of natural gas must be at least 90 %, and other components of the gas are regulated. However, different deposits have different methane compositions. These limits range from 85 % to 99 % of methane. Different composition of natural gas affects not only its properties but also the reliability of the gas transmission and distribution system and affects the work of individual end-users. This problem is especially relevant when using gas appliances with high efficiency. The problem of gas quality is important for its metering in Ukraine and in settlements with other countries. The analysis of gas composition and quality during its transportation from the field to the consumer is carried out. It is determined that in the distribution part of the gas transmission system of Ukraine there are deviations in gas quality from regulatory requirements. This reduces the efficiency of some gas appliances and throttling equipment.

Published: May 2022

Modeling and forecasting of hydrodynamic processes in the Black Sea with high resolution are important for coastal and shelf zones, because of the biggest anthropogenic pressures. Here are the processes of distribution and transformation of pollutants that emerged in the sea in different ways, the transfer and sedimentation of solid river alluvium, lithodynamic and biochemical processes and more. The peculiarities of such processes are directly related to the dynamic processes that develop in coastal areas. Development of a regional operational system for forecasting the state of the Black Sea northwestern part has to be undoubtedly considered as a significant step forward for oceanography in this area. Creation of the integrated monitoring system of the Black Sea aquatic environment as well as its separate areas by means of mathematical modeling, in conjunction with further forecasting instruments meets the modern needs of society. It will help to prevent and respond in a timely manner to crises caused by natural and man-made risks. The created system will contribute to ensuring national security, improving the quality of life of people, the development of new knowledge-intensive industries.

The problem of surface water is one of the key challenges of humanity. In accordance with the goals of research and analysis of the environmental status of water bodies are of great practical importance, as their condition further affects the quality of drinking water. The purpose of the work is to assess the environmental status of the water body. The originality of the obtained results is a comprehensive assessment based on the analysis of time monitoring data on the ecological status of water of the water body, taking into account the weighting factors of pollution indices. The study of the ecological state was carried out taking into account the integrated hydrochemical indicators. Microsoft Excel software was used to conduct the study. Google Maps was used to find places on maps and build the maps you needed to work. Microsoft Excel was used to perform calculations and build graphics. The ecological status of a water body is determined on the basis of pollution index calculations. The method of assessing the ecological status of surface waters by relevant categories has been improved through the use of weights. The assessment method is universal and can be used to study the ecological status of any water body. However, the selection of hydrochemical indicators took into account only the content of major pollutants, namely chlorides, sulfates, phosphates, suspended solids, petroleum products, compounds of copper and zinc violated. The obtained research results can be used in the development of water management plans and measures to improve their condition.
