Deethanization unit is a part of the process chain of a gas processing plant included in the ethane gas processing complex, and is designed to separate dehydrated and purified natural gas (NG) into dry stripped gas (DSG), ethane fraction and natural gas liquids (NGL). Low-temperature separation of dried and purified NG is carried out in two stages in column-type apparatuses. One of the most important blocks responsible for ethane fraction recovery depth at the deethanization unit is the gas treatment block before it is fed to the demethanization column. In this unit gas is cooled, separated and reduced, ethane-containing condensates are separated. In the present article the main technologies of natural gas processing are considered. The peculiarity of known technologies is low yield of ethane fraction due to insufficient gas cooling. The aim of the work is to increase the yield of marketable products during natural gas processing at the gas processing plant by using the deflegmation process. In order to achieve this aim, five variants of the gas treatment system before its supply to the demethanization column are analyzed in the article. Calculation studies and optimization of the natural gas treatment unit were carried out in the Aspen HYSYS software package. In order to select the optimal scheme of the gas treatment unit, in the article there were considered the following parameters: ethane fraction recovery depth, ethane concentration in DSG, temperature of the demethanizer top. It is determined that high recovery depth and low ethane losses in the demethanization column are ensured by using deflegmation process in the gas treatment system. The main technological solution is to use deflegmation of separation gas by using technological cold and isoenthalpic (throttling) expansion of gas. The result of the research is a calculation scheme in Aspen HYSYS, in which the ethane recovery depth is 96.7 %.
APPROBATION OF NEW MODELS OF SPECIAL EQUIPMENT FOR ADMISSION TO USE AT HAZARDOUS PRODUCTION FACILITIES
Authors: Zakharov Denis Yu.
Published: September 2024

The existing economic conditions caused by geopolitical risks require accelerated import substitution and import outrunning, especially in strategically important sectors of the economy, which include the Oil and Gas Complex of the Russian Federation.Especially, it is worth considering equipment directly affecting the productivity and safety of work, where it is impossible to use outdated solutions and to exceed the safe operating time. If the majority of the operated units of the definite equipment are manufactured abroad or contain a significant proportion of foreign components, there are risks of untimely repairs of the equipment itself, as well as re-equipment and technical up-grading of production facilities as a whole.The main and perspective solution of this problem is exclusively the development and commissioning of Russian equipment samples in the industry. The initiatives of equipment manufacturers, their cooperation and interaction with future consumers are key factors in the successful implementation of projects.Having created a prototype or even a serial sample, the manufacturer inevitably faces the problem of launching a new product to market. To check the safety and effectiveness of the equipment, to recommend it among the operators today is necessary during pilot tests implementation. At the same time, pilot tests implementation is expensive both in terms of the degree of material, technical and human resources attraction, and in terms of time factor. Due to the fact that equipment life cycle lasts about 10 years, spending at least one year, that is, in the best case 10 % of the time on the development of a domestic innovative product, on obtaining the results of pilot tests, after which adjusting to the production chain are seen as irrelevant and inhibiting the development of innovative machinery and equipment.The article is devoted to the description of the procedure and experience of the approbation process implementation as the fastest, most flexible and effective tool for launching to market, re-equipping and upgrading innovative equipment that can at the same time guarantee the safety of the technological processes in which it is involved.
Hyperborean Toponymy on Ancient Maps
Authors:   Financial University under the Government of the Russian Federation (FinU), Moscow, Russia, Matveychev Oleg
Published: September 2024

The article studies various versions of the localization of Hyperborea that existed in antiquity and reached the Middle Ages and Modern times. The geographical knowledge of the ancient Greeks and Romans is considered in connection with their mythological, religious, and philosophical views. The author identifies two main versions regarding the dislocation of Hyperborea — the north-eastern (Scythian) and the western. The first was based on messages from Arimaspi by Aristeas of Proconnesus, transmitted mainly by Herodotus; it was followed by Hellanicus, Pomponius Mela, Pliny the Elder. The second goes back to Pindar, who represented the Hyperboreans as anti-Scythians; it was adhered to by Hecataeus of Abdera, Pseudo-Apollodorus, and others. The author mentions that toponymy and geographical paradigms dating back to Ptolemy dominated in the European cartography in late antiquity and the Middle Ages. And the concept of Hyperborean was used mainly as a poetic synonym for the word northern. From the 9th to the 16th century, the epithet Hyperboreans mostly referred to the Russian people. The toponymy Hyperborean begins to be replaced on maps withRussian names only when Muscovite Russia was discovered by the European researchers and merchants, and when the notes on Russia were released by Matvey Mehovsky and Sigismund von Herberstein. At the end of the article, the author turns to the search for a hypothetical northern continent undertaken in the 15th–16th centuries. His descriptions, dating back to the lost book Happy Discovery (14th century), created a whole cartographic tradition, supported by Martin Behaim, Johannes Ruysch, Orontius Phineus, Gerardus Mercator, Abraham Ortelius, and gave new life to Hyperborean metaphor. However, there was no empirical evidence for the existence of the northern continent, and by the middle of the 17th century, the arctic continent had already “melted” on the majority of the maps.
Non-Metaphor: Phenomenology of Cartographic Image
Authors:   Institute of Geography, Russian Academy of Sciences (RAS), Moscow, Russia, Kagansky Vladimir
Published: September 2024

The map is a powerful cultural and epistemological metaphor for travel and landscape; demetaphorization was carried out. A map is considered in a generalized sense (but mainly on the material of geographical maps) — a solid designated scaled image of some denotative space. The map is fundamentally distinguished from non-categorical images (aerospace, etc.) by its post-categorical character. A map is a categorized image; concepts correspond to each of its fragments. The subject and obvious denotation of the classical map is the earth’s surface. The map is distinguished from the fashionable “maps of subject areas,” many types of computer graphics and other visualizations by the continuity of both the depicted (denotative) space and the map space itself and the obligatory scale of the cartographic image. Undoubtedly being an image given by visual apperception, a map is rarely entirely copy-iconic. This is an important and widespread mass card variant; but every map contains a pictorial-iconic component as an address layer that provides denotative recognition; iconicity and recognizability are not synonyms. In the center of the article are thematic special geographical maps, they are given a general interpretation; they basically use color. The basis of the work is introspection and reflection of the personal experience of the cartographer-compiler and the user of maps, the experience of reading a landscape from a map / reading a map over a landscape in cognitive journeys, methodological studies based on theoretical geography, semiotics and classification theory. Not a review or criticism of literature. The main task of the work is to clarify the epistemological, semiotic and cultural status of the map.
Digital Earth: The Geospatial Revolution and Its Worldview Implications
Authors:   Regional World Data Center for Geography, Eremchenko Eugene ,   Lomonosov Moscow State University (MSU), Russia
Published: September 2024

The paper considers the so-called “Digital Earth” — a new concept of the organization of geospatial information, formulated and implemented in practice at the turn of the 20th–21th centuries. The history of the creation of the Digital Earth is discussed, the main features that distinguish it from previously known geographical instruments, such as scale independency and projection independency, are analyzed. A typology of geovisualization methods that unveiled the evolution of geospatial method, is proposed, including maps, atlases, globes and Digital Earth. The factors that made it possible to provide the Digital Earth with its new functionality are discussed. The main one was the widespread use of images to form a geospatial context, unlike classical geovisualizations, in which the geocontext was set using cartographic signs. This feature allows you to raise and discuss the issue of the semiotics of geocontext. It is concluded that the semiotic features of the Digital Earth can be interpreted as paradoxical. Their analysis allows us to hypothesize the possibility of the existence of a carrier of metrically accurate and reliable information about the geospatial context other than signs, and that such a carrier can be considered a “zero sign” in semiotics by analogy with the zero sign in a particular sign system — mathematics. As part of this approach, the Digital Earth appears to be a heterogeneous information system using non-signs, mosaics of remote sensing data, to form a geocentric framework and allowing it to include any other geospatial products as elements. The possibilities of the Digital Earth as a new management paradigm are briefly discussed.
Domesticating Absolute Idealism
Authors:   National Research University Higher School of Economics in Saint-Petersburg (HSE St. Petersburg), Russia, Rogonyan Garris
Published: September 2024

The article offers a general overview of how John McDowell tries to “domesticate” Hegelian philosophy by fitting it into the context of contemporary Anglo-American philosophy. One of the ways of such “domestication” (or even appropriation) of Hegel’s philosophy is to bring the “identity thesis” (identity of the of the subject and object of thought) into line with the philosophical quietism of Ludwig Wittgenstein. According to McDowell, absolute idealism is quite compatible with the realism of common sense, which Wittgenstein proposed to focus on in our reflections on philosophical problems. Moreover, in McDowell’s eyes, Hegel’s philosophy has the same “therapeutic” potential as “reminders” from the Philosophical Investigations. In other words, the goal of Hegelian philosophy may also not be to find a solution to philosophical problems (primarily in the field of ontology and epistemology), but to get rid of them, provided that their conceptual source is discovered. Therefore, the “identity thesis” in Hegel’s philosophy does not mean that the world is a projection of the subjective abilities of the mind (whether individual or collective). On the contrary, it means the denial of the ontological gap between the mind and objective reality. One of the main sources of the idea of this gap, as well as many other problems of modern philosophy, McDowell considers the reduction of nature to the sphere of causal laws. In the light of this approach, it remains unexplained how external reality not only causally, but also rationally affects us. Inspired by the philosophy of Hegel, McDowell shows how the recognition of primarily a conceptual structure of external reality guarantees us not only its knowability (subjective idealism would also guarantee this), but also the objectivity of this cognition.
Relativist, Pluralist, Syncretist… An Non-Trivial Portrait of a Philosopher
Authors:   Institute of Philosophy, Russian Academy of Sciences, Moscow, Dzhokhadze Igor
Published: September 2024

In her book, Oksana Tselishcheva traces the evolution of Richard Rorty’s views “from sharp criticism to recognition” of the analytic philosophy in its dialogue-confrontation with the continental tradition. Casted himself as a kind of disciplinary provocateur in the Philosophy and the Mirror of Nature (1979), Rorty, according to Tselishcheva, mitigated his criticism by the 90s and took a stance of a peculiar “philosophical ecumenism.” This author’s conclusion, however, is not supported by thorough arguments and evidences. Rorty’s writings of the 1990s and 2000s do not allow us to suggest that his attitude towards analytic philosophy has been changing noticeably over time. The American pragmatist criticized analytic philosophers for their theoretical narrowness, underestimation of the history of philosophy, and isolationism. The linguistic turn, according to Rorty, was useful only insofar as it “turned philosophers’ attention from the topic of experience toward that of linguistic behavior,” allowing them to “break the hold of empiricism.” In the current trends and tendencies of the analytic philosophy Rorty traced symptoms of the “ontotheological” tradition’s decline. The monoideistic philosopher, who for 35 years of his life adhered to one essentially unchanged position (anti-representationalism, historicism, criticism of the empiricist dogmas), Rorty is portrayed by Tselishcheva as constantly self-doubting thinker, oscillating between “paradigms” and academic divisions, and deeply concerned with the problem of self-identification. Further, the author confines herself almost exclusively to metaphilosophical reflections (regarding the particularities of philosophy as an academic discipline and the ongoing quarrel between the faculties, communities and schools), as well as discussion of Rorty’s relationship with colleagues — analytical and continental philosophers. The most interesting in Rorty (his sui generis deflationism, reinterpretation of Hegel’s, Freud’s and Dewey’s thought etc.) remains behind the scenes. The history of philosophy here is actually replaced by the sociology and psychology of knowledge. For the sake of an adequate understanding of Rorty’s ideas, it doesn’t do much.
Hegel on Logic as Metaphysics
Authors:   University of Chicago, USA, Pippin Robert
Published: September 2024

Over the past 30 years the question of Hegel’s vision of metaphysics has become widely debated. Especially important is the issue: what does Hegel mean when he says, not that metaphysics requires an unusual, speculative logic for its exposition, but “coincides with logic.” The aim of this chapter is to offer an interpretation of this claim, with special attention to Hegel’s understanding of Kant’s transcendental logic, which Hegel both highly praises and sharply criticizes, and to his equally important attention to Aristotle, the originator of the view that logic itself has metaphysical implications. Hegel is a post-Kantian philosopher and he should not be considered as a fallback into the old metaphysics, which understood thoughts as essentialities of things (as in Scholastic philosophy or early modern rationalism). Hegel’s project in the Logic is the completion of the enterprise initiated by the founding assumption of Ancient metaphysics: that to be is to be intelligible. Accordingly the task of metaphysics is not to say of things what they are, but to say of anything at all what it must be, such that the question “what is it” can be raised.

La (re)presentación identitaria de género en el retrato. Análisis del binarismo hegemónico desde la indagación poética
Authors: Peña Sanchez Noemi , González Álvarez Miriam
Published: September 2024

In antiquity, identity was bound to the word. In contemporary times, the 'self' becomes an image. Aware of this shift, we position the portrait as a pedagogical and aesthetic tool to analyze the relationship between the signifier and the signified body. In this regard, the present study examines the use of the portrait as a strategy for (re)presenting identity. This research analyzes, from the perspective of gender studies and the intersectional approach, the presence of hegemonic binary in the discursiveness of the image. This research reinterprets, from a poetic perspective, an artistic-educational experience carried out in four educational centers on the island of La Palma (Canary Islands) and draws data from 109 students in Compulsory Secondary Education. To analyze visual and discursive grammars, various strategies are combined based on visual methodologies as a reliable means of data collection and analysis. The results obtained indicated the presence and persistence of gender archetypes and dichotomous "masculine" and "feminine" roles. On the other hand, it was observed that the journey through the different portraits invites opening up other ways of telling new stories. It proposes a critical perspective that deconstructs hegemonic visual narratives and enables the generation of counter-discourses.

Chinese Multinationals and Europe’s Geoeconomic Turn: The De‐Globalization of the Chinese ICT and Automotive Industry?
Authors: Köncke Philipp , De Graaff Nana
Published: September 2024

Amid increasing geopolitical tensions between Western powers and China over the alleged state-capitalist nature of Chinese corporate internationalization, European governments have introduced a set of political measures tightening their trade and investment regimes on grounds of national security and economic competitiveness. This article analyzes how this “geoeconomic turn” in Europe affected the internationalization of (state-backed) Chinese firms into Europe and hence the establishment of Sino-European corporate relations. With a focus on the Chinese ICT and automotive industries, we zoom in on corporate internationalization by distinguishing two modes: (a) outward foreign direct investments (greenfield investments and mergers and acquisitions) and (b) the formation of collaborative ties (strategic alliances and joint ventures) with European companies—a hitherto underexplored form of Sino-European corporate relations. Our analysis is predicated on a comprehensive dataset consolidating information on both modes of internationalization for the period 2000–2023. We show that, in relation to investment numbers, Chinese companies continue to expand into Europe, even if values are decreasing. We also find that the formation of collaborative ties (strategic alliances and joint ventures) has not halted but increased in the wake of Europe’s geoeconomic turn, indicating a further intensification of Sino-European corporate relations, though under the radar of tightening investment policies and mechanisms. When unpacking the variegated impact of the geoeconomic turn on Chinese companies’ internationalization strategies in Europe, our study also finds, however, that its ramifications vary substantively—not only per sector but also among companies exposed to varying degrees of party-state permeation. Applying a novel fine-grained measure to party-state permeation, the article shows that the geoeconomic turn seems to have affected predominantly those leading Chinese firms with a high party-state exposure.

The article examines the features, current state and prospects of Ukraine's interaction with the Gulf monarchies in the context of escalating security challenges. Authors substantiates the intensification of political dialogue between Ukraine and the GCC member states in connection with the increase in the number of official contacts in the context of the growing need for Ukraine to increase the level of political support. The qualitative characterization of official contacts is generalized, on the basis of which the main directions of such interaction are outlined. The importance of such support is confirmed, which is determined by the growing influence of the Persian Gulf states in the international arena. The authors substantiates the origins and peculiarities of the GCC member states' position on the Russian-Ukrainian war through the view of their national interests. The reasons for the interest of the Gulf monarchies in economic cooperation with Russia are highlighted and the negative consequences of this trend for Ukraine are emphasized. The impact of Ukraine's strategic documents on its current position in relations with the GCC countries is described. The negative impact of the Russia-Ukraine war on the trade and economic relations between Ukraine and the GCC is reflected. Key problems for Ukraine's foreign policy in relations with the GCC countries are outlined, referring to the current geopolitical situation, which is determined by the expansion of BRICS and closer interaction of the monarchies with Asian countries, particularly China and India, as a counterbalance to the western direction of their foreign policy in the context of a multilateral approach. The study emphasizes the need to develop a comprehensive and long-term strategy for interaction with the GCC member states in both bilateral and multilateral formats, considering the effectiveness of such an approach as outlined by the authors.
Analysis of the Temporal Trend of HDW Index for the Chernobyl Exclusion Zone during 2000-2021 yrs
Authors:   Odesa State Environmental University, Odesa, Ukraine, Koval R. V.
Published: September 2024

Climate changes have become a significant threat in the 21st century, particularly due to its impact on the forest ecosystems and the fire activity. Forest fires in the Chernobyl Exclusion Zone are a serious problem that endangers ecosystems and human life. Given the high level of radiation contamination, the forests of the Chernobyl zone regularly experience fires that often escalate beyond control. One of the crucial tools for analyzing adverse atmospheric conditions contributing to fires is the Hot-Dry-Windy (HDW) index. This index combines data on wind speed, temperature, and humidity; allowing for the identification of days with an increased fire risk. The aim of this study is to analyze the temporal dynamics of the Hot-Dry-Windy (HDW) index for the period of 2000-2021 yrs and its impact on the fire risk in the Chernobyl Exclusion Zone. In this work, we use ERA5 reanalysis data provided by the European Centre for Medium-Range Weather Forecasts (ECMWF), as well as satellite data from MODIS and VIIRS by NASA, to calculate the HDW index for the Chernobyl Exclusion Zone. Utilization of modern methods of climate data processing and analysis enables us to obtain accurate and reliable results that can be used for further research and practical implementation. The analysis of the monthly distribution of HDW index values from 2000 to 2021 yrs revealed a dependence on seasonal changes, with the highest HDW index values observed in summer months and the lowest in winter. It was also found that the HDW index shows a tendency to increase over the last decades, possibly linked to the global climate changes. The conducted analysis also confirmed a correlation between high HDW index values and fire occurrences, especially when the index value exceeds the 95th percentile. The results obtained from the analysis of the HDW index for the Chernobyl Exclusion Zone are crucial for understanding the dynamics of the fire activity and the impact of climate changes on this territory.
Assessment of the water flow regulation effectiveness by urban green spaces (on the example of Kyiv)
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Korohoda Nataliia
Published: September 2024

Ecosystem services (ES) for water flow regulation provided by urban green spaces (UGS) are an effective mechanism for keeping the ecological balance of the city. The volumes of ES depend on the effectiveness of the UGS. If the assessment of ES is based on the efficiency of the functioning based on general natural laws, universal methods can be achieved, which can be applied to any territory. It is also important to use open remote sensing data, which will allow this assessment to be used not only by scientists but also by urban planners. The purpose of the paper is to assess the effectiveness of UGS in regulating water flow based on remote sensing data and the use of open source GIS tools on the example of Kyiv. The effectiveness of each green space (or the whole blue-green infrastructure (BGI) in providing water regulation is the level of its impact on the overall water balance within the basin. Effectiveness should be assessed at two territorial levels: city-wide and local. At the city-wide level, the whole city's BGI will be assessed, and at the local level – individual UGS. The results of modeling at the city-wide level show that the BGI in sub-basins on the city's outskirts is above average in its effectiveness in regulating water flow. At the local level, it was determined that the soil and vegetation cover in most of the UGS of Kyiv determines similar efficiency levels. Converting the obtained efficiency values into volumes of ES showed that 10 % of UGSs provide ES in maximum volumes, 70 % – in volumes above average. At the city-wide level, the BGI of Kyiv provides ES in average and below the average volumes, which is observed in 19 and 2 sub-basins correspondingly. Such an assessment of the effectiveness of green spaces is a good way to demonstrate their role and value in regulating water flow, as well as to identify ways to design BGI effectively and prioritise management decisions to achieve the greatest flood control effect.
Earthquake Interactions in Eastern Taiwan: Insight from the 2024 Mw 7.3 Hualien Earthquake

Published: September 2024

Since 2000, eastern Taiwan has experienced 38 Mw≥5.5 earthquakes, leaving three seismic gaps along the Longitudinal Valley fault (LVF). In April 2024, the Mw 7.3 Hualien earthquake occurred near the LVF. Herein, we first apply comprehensive geodetic data including Interferometric Synthetic Aperture Radar and Global Navigation Satellite System to estimate two potential fault geometries and invert for the coseismic slip. Our results suggest that a transpressive WNW-dipping low-angle fault related to the Central range fault is responsible for the Mw 7.3 Hualien earthquake. We then perform the Coulomb stress analysis to probe earthquake interaction in eastern Taiwan. The increased stress of ∼2.6 bars due to the preceding major earthquakes at the hypocenter of the 2024 event significantly pushes this fault toward failure. Moreover, the conjugate LVF and the Milun fault are activated, and some aftershocks are promoted here. Finally, we note that the Coulomb stress changes from historical earthquakes and the 2024 Hualien earthquake exert positive stress on the seismic gaps in the northern LVF, potentially influencing future ruptures.
Selectivity hypothesis and task bind: Explaining gender difference in NPD’s cost information and control adoption
Authors: Wardani Rika Alvira Brisa , Jatiningsih Dyah Ekaari Sekar
Published: September 2024

Research aims: This study aims to examine how gender will differentiate the effect of cost information and management control system adoption during the New Product Development (NPD) process. The importance of such research lies in the suggested development of gender-diverse teams to achieve optimum performance.Design/Methodology/Approach: An experimental design was employed to test proposed hypotheses. Data from 117 Accounting undergraduate students as surrogates of professional NPD designers were analyzed using Analysis of Covariance (ANCOVA).Research findings: Results revealed that female designers, due to comprehensive processing and stereotype threat, achieved more cost-effective designs with specific information and diagnostic control systems. In comparison, males would achieve better performance using relative information and designing in interactive control since they tended to be heuristic and free from stereotyping.Theoretical contribution/Originality: This research confirms gender differences in NPD. The explanation using the selectivity hypothesis and task bind mechanism contributes to the literature by supporting clear causal relationships in gender-related NPD contexts.Practitioner/Policy implication: In NPD, management should consider the proper presentation of information across specific users, including across teams with gender variability. Further, the design of the management control system should consider variability once the gender-diverse team has been developed.Research limitation/Implication: The causal relationship in this study was limited to a specific experimental setting, which did not reflect all complexities in practice. However, the interplay between variables under study leads to the avenue for future research to broaden the test into different metrics of NPD performance, types of information, and possible designer variability.

Published: September 2024

The aim of endodontic treatment is to prevent and treat apical periodontitis. To determine the outcome of endodontic treatment, clinical and radiographic evaluations need to be done at the follow up appointments. After complete assessment, the result of endodontic treatment can be categorized as successful or failed based on clinical and radiographic features. It can also be classified as healed, healing or diseased depending on the periapical status of the treated tooth. This review article includes both these criteria. It explains the clinical and radiographic features and their role in differentiating successful and failed cases. It also emphasizes on the importance of patient related factors, iatrogenic errors and post treatment factors like coronal seal that can directly influence the outcome of endodontic treatment.
Comparative evaluation of anesthetic efficacy of buccal & palatal infiltration of maxillary permanent first molar: An in vivo study
Authors: Swati Swati , Nagpal Ajay Kumar , Kumar Sunil , Sharma Abhishek , Rahman Muhammad Mutiur
Published: September 2024

An essential pre-requiste to success in dentistry is to achieve good quality local anesthesia. Local anesthesia forms the backbone of pain control technique in dentistry & there has been substantial research interest in finding safe & more effective technique for maxillary 1st molar.

The purpose of this prospective, randomized, single-blind crossover study was to evaluate the anesthetic efﬁcacy of a combination of buccal and buccal plus palatal inﬁltration of the maxillary ﬁrst molar.

In a crossover study, 42 participants received two maxillary first molar injections at separate appointments spaced by at least a week. Each side of the mouth acted as either the experimental or control group. The anesthetic used was 2% lidocaine with 1:80,000 epinephrine.One injection set consisted of a buccal infiltration of 1 mL of 2% lidocaine with 1:80,000 epinephrine followed by a palatal infiltration of 0.5 mL of the same anesthetic two minutes later. The other set involved a 1 mL buccal infiltration of 2% lidocaine with 1:80,000 epinephrine followed by a same palatal infiltration, where only the needle pierced the palatal tissue. The first molar was tested for pulp sensation using an electric pulp tester five minutes after the final injection. The testing continued at two-minute intervals for ten minutes, reaching a maximum of 80 readings. Anesthetic success was defined as the absence of a response to two consecutive readings of 80 on the electric pulp tester. If a participant did not achieve anesthesia within ten minutes, they were excluded from the study. The depth of anesthesia was monitored throughout using the electric pulp tester. Pulp test readings were also taken on the buccal and lingual surfaces of the first molar five minutes after the final injection.

The success rates were 78.6% for the buccal inﬁltration and 92.8% for the buccal plus palatal inﬁltration. The difference was not statistically signiﬁcant. The buccal plus palatal inﬁltration signiﬁcantly increased the incidence of pulpal anesthesia from 21 minutes through 57 minutes. Although there was an increased incidence of pulpal anesthesia with the combination buccal plus palatal inﬁltration, anesthesia was not provided for 60 minutes.

In conclusion, adding palatal infiltration of 0.5ml of 2% lignocaine with 1:80,000 epinephrine with the buccal infiltration did not significantly increase the anesthetic success in maxillary first molar.
Unusual occlusal morphology of permanent maxillary second molar and mandibular first molar: A case report
Authors: Kaur Harpuneet
Published: September 2024

Typically, maxillary second molars have a different number, size, and arrangement of cusps than molar teeth, which have four cusps and a square occlusal surface. Mandibular molars are considerably less likely to have an oblique ridge, and buccal accessory cusps are very rare. This case study aimed to describe a unique case of a permanent maxillary second molar and a permanent mandibular first molar with an oblique that resembled the maxillary molar crown.

Published: September 2024

It is crucial to have a thorough grasp of the anatomical changes in the roots and root canals of third molar teeth, as well as the endodontic consequences of these variations, before beginning any endodontic therapy. The key to the success of endodontic therapy is the cleaning and shape of the root canal. While treating curved canals, a few procedural mistakes might occur, such as ledge development, obstructions, and apical transportations and perforations. It was advised utilizing precurve files or flexible NiTi files to minimize procedural errors. Third molars face a variety of anatomical differences, such as merged canals, C-shaped canals, curved roots, and bayonet roots. Curved canals have become more common and been discovered to be comparatively higher in mandibular third molars (3.3 to 30.92%) as opposed to maxillary third molars (1.33 to 8.46%).

The following article presents a case report of the endodontic treatment of a mandibular third molar with severely curved canals and highlights the various disciplines and modifications employed for its management.

It is essential to give thorough attention to the radiographic assessment, access cavity preparation, and exploration in order to successfully navigate curved canals.

The paper, entitled The time of the offence in the Polish penal law (The basic substantive of legal issues)”, is to show the timing issues of human behaviour, behaviour that is subject to criminal valuation.
Considerations begin with the presentation of philosophical views on the issue of time and its passing from ancient times to our modern times. In the next part of the paper it is outlined the problem of the time of the offence before the entry into force of the Criminal Code of 1997, in particular with regard to legal status under the Criminal Code of 1932 and the Criminal Code of 1969.
Development of the title issues are considerations over whether art. 6 § 1 of the Criminal Code of 1997 is a carrier of a legal definition of the expression “time of the offence”. Following the interpretation of the contents of that provision in line with the concept of derivational interpretation of the law by Professor Maciej Zielinski, presented thesis is achieved justification.
In the next section of the work, attempt to differentiate expressions “running time”, “time of failure” and “the effect of the time”, while indicating that only the first two terms characterize the behaviour of the perpetrator of the time involving the commission of an offence.
Another chapter of the work is devoted to the role of the time of the offence on the basis of the fundamental principles of criminal responsibility, such as lex retro non agit (law is not retroactive), nullum crimen sine culpa (no crime without guilt) or lex mitior agit (principle of the law more favourable). The discussion in Chapter 6 is devoted to a specific group of offences that are referred to as “crimes over time”. The crimes of these include, among others factors constant, continuous crime, permanent crime, collective crime. A characteristic feature of these constructs is that the behaviour of the perpetrator of a criminal violation of a prohibition lasts longer than just a short while.
Another part of the work deals with the consequences that result from the adoption of one of the two models, determining the time of the commission a crime over time. The first model assumes that the time of a crime is a time of a last behaviour of the perpetrator. The second model assumes that the time is determined by all behaviours taking by perpetrator.
The final chapter of dissertation discusses time of the offence through the prism forms, which this action can be allowed. According to the Criminal Code of 1997, we can distinguish: stage forms [preparation, attempt, achievement (accomplishment)] and forms of cooperation (single perpetration, complicity, management perpetration, perpetration of recommendation, icitement, aiding and provocation).
It was described the aforementioned criminal justice agencies, often referring to the views of science and reaching for the rich judicial decisions.

Introduction. The aggravation of migration problems both in Russia and in other countries actualizes the study of migration relations, identifying the causes and consequences of emerging problems. Research methodology. The research is based on a systematic approach, as well as provisions on the correlation of objective contradictions, problems and conflicts. Results. The manifestation of internal contradictions of various elements of the migration relations system, as well as contradictions between the elements of this system, in the problems of migration is revealed. In this aspect, the problems of shadow and unstable employment of migrants, the problems of migrants’ social dependency, the contradictory influence of migration on demographic processes and socio-economic development of Russia, on the preservation of Russian identity are considered. It is proved that adequate forms of resolving contradictions in the system of migration relations do not allow problems to escalate into conflicts, but promote equal coexistence of representatives of various national ethnic groups and cultures on the territory of Russia, effective participation of migrants in the economic, social and cultural life of Russian society. Migration flows have a contradictory effect on solving problems in the field of socio-economic development of the country: they stabilize the situation with labor resources, and reduce the quality of the workforce; resolve the contradiction between the needs of demographic reproduction of the Russian population and natural population decline and pose a threat to the preservation of Russian identity, etc. Conclusion. The imperfection of migration policy, its inadequacy to the challenges of the current migration situation, the lack of adequate forms of resolving the contradictions of this system lies at the heart of the aggravation of problems and tensions in migration relations, and the emergence of conflicts. Due to the fact that conflicts can lead to the intensification of extremist and terrorist activities with devastating consequences, in order to avoid them, society and the state must learn how to prevent conflicts in a timely manner and successfully resolve them so that migration processes can realize their positive potential.

Introduction. The high influence of territorial, agroclimatic, infrastructural and other factors causes significant economic differentiation at the regional level. The proven influence of the economy’s condition on construction activity leads to the conclusion that differences in the economic level of development also give rise to stratification in the housing construction sector across the constituent entities of the Russian Federation. Еmpirical analysis. Continuing the authors’ work on this topic, we will expand the work of previous researchers by searching for the most dependent indicators of housing construction of economic development. To do this, we introduce per capita indicators into the calculation, as well as growth indices for indicators over a long (more than 20 years) period of time. Results. During the work, it was established that a high degree of housing construction dependence on GRP is observed only in current values for a certain year (in our case, 2022), while per capita indicators do not show a significant level of correlation. One can also note the mutual dependence of the housing stock and GRP growth dynamics (growth indices for both indicators). For other indicators, the quality of correlation models is unsatisfactory, which indicates the absence of mutual connection. Cluster analysis demonstrated a high level of regional differentiation in housing construction indicators and related indicators of economic development. Only 10 subjects of the Federation can be classified as prosperous regions with a high level of housing construction. The remaining regions, due primarily to economic factors, do not demonstrate high-quality development of housing construction.

Introduction. The relevance of the topic under consideration, on the one hand, is due to external factors, when decisions of a strictly political nature by the Western world leaders and subsequent economic sanctions “cut Russia off” from a number of important technologies. On the other hand, the lack of a coherent domestic economic policy leads to a mismatch of targets at the national and regional levels. subjects of economic activity, both at the micro and macro levels. In this regard, the development of methodological foundations that allow for the integration of economic entities at the macro level, while qualitatively improving the efficiency of management is extremely important. Theoretical analysis. The article analyzes and evaluates the international experience of technological development management. The main directions of improving management efficiency have been identified. A structural analysis of the subjects of regional management was carried out, which allowed us to identify the main problems. Results. The necessity of using a project approach based on regional technology platforms is substantiated. An organizational model of regional management is presented, which allows for dynamic technological development in strict compliance with all principles of sustainability. Conclusion. Qualitative improvement of management efficiency is possible only on the basis of integration of both different types of management and target indicators of management entities. Such integration should be based on a new industrial policy and represent a permanent process.
