Las especies híbridas se adaptan mejor a diferentes ambientes que sus progenitores. El pino híbrido (pino híbrido PEE×PCH) entre Pinus elliottii Engelm var. elliottii × Pinus caribaea Morlet var. hondurensis (Sénéclauze) W.H. Barrett & Golfari ha mostrado buen desempeño en regiones subtropicales de Australia, Brasil, Estados Unidos, Sudáfrica y Argentina. Sin embargo, su principal limitante en la expansión del área de plantación es la susceptibilidad del material al daño generado por las bajas temperaturas. Para ello se evaluó por medio de un análisis de componentes principales, como los caracteres asociados a crecimiento, desarrollo fenológico y diferentes condiciones de micrositio afectan a 3 familias de pino híbrido PEE×PCH y a su parental femenino Pinus elliottii. Se encontró un efecto diferencial del daño por bajas temperaturas a nivel sitio de plantación (BAJO y ALTO), especie (PEE y PEE×PCH), pero no a nivel de familia híbrida (F12, F28 y F51) afectando a todas por igual. Su crecimiento inicial y la rápida respuesta a condiciones favorables de crecimiento, son los principales factores que causan la susceptibilidad a bajas temperaturas.

Distribution of the invasive ambrosia beetle Xyleborinus attenuatus Blandford, 1894 (Coleoptera: Curculionidae: Scolytinae) in the Czech Republic (Central Europe)
Authors: Fiala Tomáš , Holuša Jaroslav
Published: March 2024

In Europe, Xyleborinus attenuatus Blandford is considered an invasive bark beetle native to East Asia. We used the results of many local surveys and data from private and museum collections to get information on the distribution and abundance of X. attenuatus Blandford in the Czech Republic. The ambrosia beetle X. attenuatus Blandford is probably widespread throughout the territory of the Czech Republic, from the lowlands to the mountains, and has one generation per year in Central Europe. The flight activity lasts from mid-March to May, F1 adults emerge in August and September and overwinter in wood or in the ground under an infested tree. X. attenuatus Blandford predominantly occupies soft deciduous trees and so far there economic damage have not been reported yet. However, X. attenuatus Blandford is a vector of ambrosia fungi Ambrosiella spp. and Raffaelea spp., and therefore this ambrosia beetle should be monitored.
An Examination of Work Conditions and Well-Being of Slovene Train Drivers
Authors: Murko Danica , Khawaja Sarwar , Qureshi Fayyaz Hussain
Published: March 2024

Background and purpose

While the occupation of a train driver can be likened to other transportation professions like truck or bus drivers, it is essential to note that there are distinct hazards exclusive to this role that have a notable impact on the mental and physical well-being of train drivers. The study aims to define personal characteristics, work organisation and work characteristics, professional development and work in general in connection with risk factors among employees who perform the work tasks of train drivers in railway transport.

Methodology

The study on train drivers in Slovenia was conducted with 179 participants, representing 13.3% of the total population of train drivers. The sample was predominantly male and varied in age, most hailing from the Podravska region. The OPSA digital tool was used to analyse risk factors and gauge psychosocial stress across 17 areas, using a questionnaire split into two sections. Data was collected through online and physical surveys, with voluntary and anonymous participation.

Results

The study found that the personal characteristics of train drivers do not significantly impact their perception of workplace workload. While professional development factors negatively influenced workload perception, the impact was not statistically significant. However, general work characteristics strongly impact how train drivers perceive their workload. These findings suggest that interventions should focus on modifying general work characteristics to improve train drivers’ work conditions.

Conclusions

These findings have important implications for the railway industry. They suggest that interventions aimed at improving the work conditions of train drivers should focus on modifying general work characteristics rather than targeting personal characteristics or professional development factors. Future research should explore these relationships and develop strategies to mitigate the identified risk factors.
Jan Bavinck’s (1826-1909) Reformed Piety: Experiential and Holistic
Authors: Leiva Israel José Guerrero
Published: March 2024

This article introduces the theology of a neglected figure in the Dutch Reformed (Gereformeerde) tradition of the nineteenth century: Jan Bavinck (1826-1909), the father of Herman Bavinck (1854-1921). The approach to his theology is done by describing his definition of piety (vroomheid or godzaligheid), a fundamental subject within the Reformed tradition. The relevance of piety is briefly described in the theology of John Calvin (1509-64) and the Nadere Reformatie in order to argue for the necessity of exploring Jan Bavinck’s description of the nature and application of godliness. After analysing some primary sources, I argue that Jan Bavinck’s theology of piety can be described as experiential and holistic. In this way, it may be considered, in general terms, as a bridge between the praxis pietatis of old Calvinism – characterised by Calvin and the Nadere Reformatie theologians – and neo-Calvinism, represented by Abraham Kuyper (1837-1920) and Jan’s son Herman Bavinck.
The Multifaceted Work of Christ: Herman Bavinck’s Doctrine of Atonement as Both Corrective and Retrieval
Authors: Crosby Sarah Killam
Published: March 2024

This essay examines Herman Bavinck’s doctrine of atonement within his treatment of Christ’s humiliation in volume three of his Reformed Dogmatics. Through an investigation of Bavinck’s critiques of key nineteenth century theologians and of Bavinck’s own constructive account of the atonement, I show that Bavinck intended his theology of Christ’s work to serve as a corrective to the dominant approach to the theology of the atonement in his day. Against what he considered one-sided views of Christ’s work, I argue that Bavinck sought to offer an account which emulates Scripture in its multifaceted character. This theology further sought to retrieve and build upon historical Christian theology, most notably that of Anselm and especially the Protestant Reformers, in its focus on Christ’s vicarious satisfaction as the central (though not only) concern of his redeeming action. This exploration of Bavinck’s doctrine of the atonement not only deepens our understanding of Bavinck’s theological method but has relevance for broader studies of nineteenth and early twentieth century conceptualizations of Christ’s person and work and shows Bavinck’s attractiveness for contemporary constructive approaches to the atonement.

Published: March 2024

This study aimed to describe the impact of the COVID-19 pandemic and related public health decisions on dental services. A retrospective study was conducted using secondary data on dental services (2019–2021). Data were obtained from the Latvian National Health Service and the Centre for Disease Prevention and Control and analysed using descriptive statistics and data visualisation methods. In the first wave of COVID-19, the frequency of routine dental services decreased by 81.6% at the patient level, which coincided with the restrictions imposed as public health measures. The amount of regular dental manipulations returned to its previous level immediately after lifting restrictions. Still, they decreased to a more moderate extent (not exceeding 25% decline) with the beginning of the second wave. We observed a decrease in all manipulations, regardless of their aerosol-generating risk, and no increase in preventive manipulations that could be performed without any physical contact. We conclude that the most significant decrease in the availability of services was directly linked to existing public health measures. It seems that these measures allowed time to adapt the clinics to the new sanitary requirements, further ensuring continuity of service provision.

Even though more than two years have passed since the global pandemic started, COVID-19 continues to impact children all over the world. The most common course of SARS-CoV-2 infection in children is short term with no or mild symptoms. However, there are two long-term consequences: long COVID and multisystem inflammatory syndrome (MIS-C). A post-COVID19 programme for children has been created in Latvia; however, we know that the availability of this service is limited. We developed an online survey so that we could screen for those paediatric patients with long COVID who needed to see a specialist as soon as possible. The cross-sectional study from 1 November 2021 to 27 March 2022 included 220 patients. In our study, the most frequent symptoms in the age group < 1.5 years were irritability (50%), mood swings (50%), persistent cough (33.3%) and loss of appetite (33.3%). In the group aged 1.5–5 years, a persistent cough (54.4%), mood swings (43.9%) and irritability (42.1%) were the most common symptoms, while in the group aged 6–10 years, fatigue (56.6%), abdominal pain (55.3%), headache (50%), and mood swings (50%) were seen most often. Meanwhile in the 11–18 age group, impaired physical activity (66.7%), fatigue (62.3%) and drowsiness (62.3%) were the most frequently seen symptoms.
Using the Health Belief Model to Predict Vaccination Intention in Unvaccinated Adults in Latvia During the COVID-19 Pandemic
Authors: Feldmane Sandra , Mārtinsone Kristīne , Perepjolkina Viktorija
Published: March 2024

Vaccination is a global health development success story that saves millions of lives every year and reduces the risk of getting various infectious diseases, including COVID-19. At the end of 2021, a rapid increase in the size of the population infected with COVID-19 and a low vaccination coverage were observed in Latvia (Centre for Disease Prevention and Control, 2021). Also, despite the available vaccines, by the beginning of May 2022, only 60.6% of the population of Latvia had completed the full course of vaccination against COVID-19. According to the Ministry of Health, the vaccination process is characterised by variability and flexibility, and in general, vacci-nation rates have declined in recent years. Therefore, the aim of the study was to investigate the vaccination predicting factors of unvaccinated adults in Latvia using the Health Belief Model (HBM) during the COVID-19 pandemic. The study sample consisted of 539 respondents aged 18 to 75 years (M = 45.35, SD = 15.70), who were not vaccinated against COVID-19 and who had to make a decision to vaccinate or not, and who were part of a representative sample of Latvian residents (n = 1017). The data was collected in September and were analysed using Spearman’s rank correlation coefficient and multivariate linear regression analysis. A statistically significant moderate strong positive correlation was shown between vaccination intention and all six vaccination motives as perceived benefits (r = 0.40–0.44, p < 0.01); statistically significant but weak positive correlation between vaccination intention and risk appraisal as perceived threat (r = 0.20, p < 0.01) and COVID-19 experience as cues to action (r = 0.20, p < 0.01); and statistically significant negative but weak correlation for vaccination intention and fear of vaccination as perceived barriers (r = –0.21, p < 0.01). The results revealed a statistically significant positive association of vaccination intention and the components of HBM: perceived threats, perceived benefits and cues to action, as well as a statistically significant negative association with perceived barriers. The results revealed several factors that predict vaccination intention, explaining 32% of the variation in vaccination intention: education level, perceived threats, perceived benefits, perceived barriers, and cues to action. Higher levels of education, higher perceived threat of contracting COVID-19, many different social motives for vaccination (e.g., to be able travel), confidence that the vaccine will not cause significant side effects and long-term consequences, and experience with COVID-19 are factors that predicts an individual’s intention to vaccinate against COVID-19.

Published: March 2024

Private–public partnership is a collaboration between two major sectors of a municipalities economy. It is a so called “win-win” partnership, where both parties can benefit in achieving their planned goals while working jointly. In December 2019, in China, the first reported cases of COVID-19 were detected. The virus spread quickly throughout China and reached Latvia in March 2020. In this study we analyse the role of private–public partnerships in organising effective COVID-19 testing of the population in Latvia. By 1 June 2020, Latvia had the 3rd lowest incidence of COVID-19-caused deaths per 100,000 inhabitants. This study included a systematic review, data acquisition, analysis of the findings, and conclusions were drawn and discussed. During the 1st wave of the pandemic, the private sector collected and conducted more than 95% of the COVID-19 testing in Latvia. The study showed that there could be many contributing factors to success of Latvia during the 1st wave of the pandemic, one of which was that Latvia seemed to rely more on the private sector to organise the testing, which seemed to pay off at first.
Applying Section 140 Paragraph 71 of the Criminal Procedure Law of the Republic of Latvia During the COVID-19 Pandemic
Authors: Neimane Liene
Published: March 2024

The goal of the legislator, by supplementing Article 140 of the Criminal Procedure Law of the Republic of Latvia with Part 7.1, was to make the regulation of criminal proceedings more efficient, to speed up the execution of investigative activities, as well as to facilitate the organisation of court work in connection with the planning of court sessions and the conduct of trials. During the spread of the COVID-19 infection, the mentioned article provided an opportunity for the achievement of epidemiological safety goals to conduct criminal procedural activities using a video conference. The article “Application of the procedure set out in Article 140, Part 7.1 of the Criminal Procedure Law during the COVID-19 pandemic” provides an insight into how the regulation of the criminal procedure, which has been streamlined in theory, is not used in practice, and during the spread of the COVID -19 infection, its use was not effective enough. According to the Author, the problem that has arisen in practice — insufficient use of the legal norm — is related to the insufficient knowledge of industry specialists, including the inability to apply a uniform interpretation of the legal norm.
Mental Health Attitudes in Bosnia and Herzegovina
Authors: Goreta Andrea , Long Susan M.
Published: March 2024

Mental health is not openly discussed in Bosnia and Herzegovina and there is a dearth of research on this topic, particularly related to general mental well-being. A convenience sample recruited online of 281 people from urban, suburban, and rural areas in Bosnia and Herzegovina reported their attitudes and knowledge about mental health and illness. Despite mental health being a publicly taboo topic to discuss, participants had fairly positive attitudes about mental health and illness. These findings differed by religion (ηp2 = .06) and nationality (ηp2 = .14). Participants who identified as agnostic or Muslim (as opposed to Catholic or Orthodox) had more positive attitudes toward people with mental health. Additionally, Serbian participants (versus Bosnian or Croats) expressed the least positive attitudes about mental health issues. Finally, younger people and more educated people had more positive attitudes about mental health (R2Adj = .10). This suggests cultural and religious differences in the ways that mental health is conceptualized and acknowledged.

Authors: Hughes Jennifer L. , Treadwell Kimberli R. H. , Mendoza Albee T. O.
Published: March 2024

The APA Guidelines for the Undergraduate Psychology Major, now on version 3 (APA, 2023), includes personal and professional development as its fifth goal. Because of this, faculty are increasingly being asked to teach about career exploration and professional development in their psychology courses (Halonen & Dunn, 2018; Spencer, 2019). This article covers readings developed by Psi Chi, the International Honor Society in Psychology, which can be useful for instructors when selecting content about career exploration and professional development for their courses. These readings could also be useful for faculty to give to undergraduate psychology students when advising them. In this article, three inexpensive and useful Psi Chi eBooks are discussed, which cover career exploration and joining the workforce, graduate school, and business-related careers. In addition, articles from Psi Chi’s magazine, Eye on Psi Chi, are presented. Those articles are grouped into the following categories: career exploration and joining the workforce, graduate school, professional development, and specific areas of psychology. These student-friendly and content-rich articles are free to access for students and faculty.
“Not Liking the Look of This”: Examining the Relationship Between COVID-Related Social Media Exposure and Mental Health Symptoms
Authors: Punjabi Pooja , Jensen Anna , Mota Ortega Ashley , Perez Aleksandria
Published: March 2024

The COVID-19 pandemic led to the implementation of quarantine measures, resulting in widespread isolation and encouraging more online engagement, especially around information related to the novel COVID-19 virus. Uncertainty reduction theory suggests that individuals who sought this information were likely exposed to distressing media content that increased their stress, rather than reducing it as intended. Indeed, research has identified COVID-19 as a traumatic stressor capable of eliciting PTSD-like responses, with recent studies demonstrating associations between higher levels of media exposure to COVID-19 information and greater psychological distress. However, there is some evidence to suggest potential adaptive uses of social media related to the pandemic. Moreover, scarce research exists on the actual pandemic-related content that individuals have been exposed to on social media. The present study utilized quantitative and qualitative methods to examine the relationship between mental health outcomes and positive/negative exposure to COVID-19-related social media, as well as the moderating influences of positive COVID-related social media exposure and previous trauma, respectively, in college students. Participants completed an online survey assessing their exposure to COVID-19 content on social media, mental health symptoms, and previous trauma exposure. Our quantitative results indicated significant associations between high fear following a COVID-19 post and more depressive, B(SE) = 0.13(0.04), p = .003, anxiety, B(SE) = 0.26(0.05), p < .001, and posttraumatic stress symptoms, B(SE) = 0.27(0.09), p = .003, with previous trauma moderating fear and anxiety symptoms, B(SE) = 0.59(0.23), p = .02. Our thematic analysis identified news stories as the main type of content that elicited both negative and positive emotions among participants. Further research is needed to continue to understand how to better mitigate the risk of exposure to negative social media content on mental health outcomes.

The problems of the quality of diagnostics at the prehospital stage remain relevant. Diagnostic errors represent an urgent medical and social problem. The purpose of the study was to study the continuity in the provision of medical care to patients with acute surgical pathology of the abdominal organs in terms of the coincidence of the diagnoses of the emergency medical teams and the emergency hospital. The statistical data of the State Budgetary Institution St. Petersburg Research Institute of Emergency Medicine named after I. I. Dzhanelidze for the period 2015–2022, content analysis, statistical and analytical methods were used. Study results. Among patients with acute surgical pathology of the abdominal organs, a significant discrepancy in the diagnoses of prehospital and inpatient stages was revealed: “acute cholecystitis” in the diagnosis of emergency medical teams was confirmed by the hospital in 51.2% of cases, “ectopic pregnancy” — in 28.9% of cases, “acute appendicitis” — in 20.7% of cases, “acute pancreatitis” — in 6.7% of cases, “acute intestinal obstruction — in 5.7% of cases,” perforative ulcer” — in 3.1% of cases. 36.1% of patients received an unverified diagnosis of acute abdominal surgical pathology. Conclusion. Defects in the formulation, execution or coding of a diagnosis — an indicator of unsatisfactory qualifications of a medical worker and the quality of the organization of the medical and diagnostic process. It is the diagnosis, as an integral indicator of the clinical thinking of a doctor (paramedic), that is of exceptional importance, since it performs cognitive-logical, scientific, statistical and legal functions. However, reasonable overdiagnosis in the prehospital stage of emergency medical care is welcome, as underestimating the severity of the condition in conditions of limited diagnostic capacity and time deficit can have severe consequences for the patient.The tasks of clarifying the diagnosis, determining the indications for hospitalization and further tactics are designed to solve inpatient emergency departments with real medical and diagnostic, material and technical and personnel resources.

Purpose. Conduct an analysis of projects of various inpatient emergency departments and identify optimal planning solutions. Methods. To analyze the projects of various inpatient emergency departments and search for optimal planning solutions, it is possible to use simulation modeling. This approach allows you to create a virtual model of the system and conduct many scenario tests in order to evaluate the efficiency and optimize the work of departments in various conditions. Using simulation modeling, three models of inpatient emergency departments of various sizes (1000, 1200 and 2500 m2) were created. The definition of functioning features was carried out with the same threshold value of the incoming flow of patients — 150 per day. In addition to the structural components of the departments, a “point of primary decision-making” was singled out. After the experiments, a comparison of the obtained statistical data was carried out. Results. As a result of the study, on the model of an inpatient emergency department with an area of 1200 m2 and 2500 m2, there were no queues in the process of work at the “point of primary decision making”. At the same time, on a model with a total area of 1000 m2 with the same flow of patients, a queue was formed at the established “primary decision point”, waiting for 10 minutes of model time, which was due to the initial small area in the waiting room. Conclusion. Based on the data obtained, it was concluded that the optimal design solution for the creation of an inpatient emergency department is the department area of 1200 m2.

In order to monitor injuries and improve the provision of medical care to patients with injuries abroad and in the Russian Federation various models of injury registers (trauma registers) are used. The purpose of the study: to form and test a working model of the regional register of patients with injuries according to the registers of compulsory medical insurance accounts. Materials and methods: a register of patients with injuries treated in hospitals has been formed St. Petersburg for the period 01.01.2015–12.31.2022. The register contains information about 1162023 cases of medical care for patients with injuries of various localizations (ICD‑10 codes: S00.0–T09.9). To study long-term results, the register includes information on all cases of medical care provided to patients after discharge from the hospital. The results of the study: an analysis of the gender and age structure of patients with injuries in St. Petersburg, an analysis of the structure of patients in adult and children’s hospitals by localization of injuries and by the option of providing medical care: cases without hospitalization; cases with hospitalization without treatment in the intensive care unit; cases of hospitalization with treatment in the intensive care unit. The indicators of hospital mortality and annual survival of patients treated in intensive care units were also analyzed.

The article presents an analysis of the staffing of the ambulance service in various regions of the Russian Federation. The problems of personnel shortage are outlined and possible ways of their solution are presented. The purpose of the study was to analyze the staffing of the ambulance service in the constituent entities of the Russian Federation.  Methods.  A  retrospective  analysis of the reporting forms of federal statistical observation No. 30  «Information  on a   medical organization» was carried out on the availability, staffing and part ‑time ratio of doctors working in emergency medical care in the Russian Federation, in federal districts and their subjects for the full period from 2016  to 2021.  Results. According to the results of the analysis, a  trend  of aggravation of the personnel shortage in various regions of the Russian Federation was revealed. One of the solutions to this problem was to change the curriculum for 5th and 6th year students, after which an increase in students’ interest in emergency medicine was revealed. Another solution to this problem was proposed by the department of the Ivanovo region  —  to increase the financial support of full ‑time employees of the ambulance service through various programs. Thanks to these changes, it was possible to increase the staffing of medical personnel by 20% in the period from 2021   to 2023.  Conclusion. To address the staffing shortage issue, various solutions are possible, including increasing the interest of young professionals through changes in curricula and increasing the salaries of emergency medical staff through various funding programs.

Subregional Differentiated Safety Factors Design Based on Nonprobabilistic Structural Reliability
Authors: Xu Yusheng , Wang Xiaojun , Wang Lei , Shi Qinghe , Gong Jinglei , Yu Yongbo
Published: March 2024

The structural safety factor is an essential parameter in aircraft design, representing the ratio of the design load to the operating load. Traditional design methods rely on subjective determination of safety factor values based on experience, lacking objectivity in quantifying uncertainty. However, with advancements in aircraft design technology and increasing competition in the commercial space market, new-generation hypersonic aircraft with complex load environments require a more optimal approach. Applying a uniform safety factor to each component within subregions of the aircraft leads to overly conservative results and impacts flight performance. To address this limitation, a design scheme that incorporates subregional, differentiated safety factors is necessary. This approach allows for better material utilization and ensures compliance with safety requirements. This paper utilizes reliability-based design optimization theory to consider uncertainty in structural systems. It establishes a mapping relationship between structural reliability and differentiated safety factors, providing safety under uncertainty while guaranteeing weight reduction. Additionally, this paper develops a subregional, differentiated safety factors distribution program to determine the safety factors of different subregions of the structure. Consequently, a refined subregional differentiated safety factors scheme that balances safety and economy is derived.

Published: March 2024

As the world faces the threat of the coronavirus pandemic it is imperative that people comply with the prevention guidelines provided by the experts. Despite the prevention guidelines in place, the compliance rates among individuals differ. In order to improve voluntary compliance with the COVID-19 prevention guidelines, it is important to examine the personality attributes owing to the individual differences in compliance rates. The objective of this study is to explore the relationship between Compliance with COVID-19 prevention guidelines and Risk Propensity, Locus of Control, and Intolerance of Uncertainty respectively. The study employed a survey method wherein standardized questionnaires were administered to participants from different cities of India. The results indicate that there exists a significant negative correlation between Risk Propensity, External Locus of Control and, Intolerance of Uncertainty and Compliance with COVID-19 prevention guidelines. The results also demonstrate a significant positive correlation between Internal Locus of Control and Compliance with COVID-19 prevention guidelines. The findings suggest the importance of a plurality of messages in communication by the experts and officials. Theoretical and quantitative findings are elaborated in detail.

Objectives:

The influence of the autonomic nervous system on the heart can be quantified by assessing changes in the heart rate variability (HRV) during orthostatic challenge and exercise. However, the combination of oscillatory lower body negative pressure (oLBNP) and isometric handgrip exercise (IHE) on HRV has not been previously investigated. Therefore, the present study aimed to assess the effects of (oLBNP) at sympathetic (0.1 Hz) and parasympathetic (0.25 Hz) frequencies and IHE at 30% of maximum voluntary contraction (MVC) on HRV in normal healthy individuals.

Materials and Methods:

We conducted a cross-sectional study on 18 healthy male subjects. Beat-to-beat blood pressure, lead-II electrocardiogram, and oLBNP chamber pressure were recorded continuously during oLBNP at 0.1 and 0.25 Hz for 3 min each and IHE at 30% of MVC (for 4 min) along with oLBNP at 0.1 or 0.25 Hz (oLBNP was added in last 3 min) each followed by HRV analysis.

Results:

The oLBNP at 0.25 Hz reduced the root mean square of successive inter-beat (RR) interval differences significantly as compared to baseline values and came to normal during the recovery phase (P = 0.008). The absolute power of the high-frequency band (HF power), Poincaré plot standard deviation perpendicular to the line of identity (SD1), and percentage of successive RR intervals that differ by more than 50 ms (pNN50) were also reduced significantly during oLBNP at 0.25 Hz and when IHE at 30% of MVC (IHE) was added to oLBNP at 0.25 Hz as compared to baseline (P < 0.05).

Conclusion:

oLBNP and IHE could be used as a non-invasive haemodynamic stressor to assess the neurocardiac axis and its mechanism of action during orthostatic stresses.

The article is devoted to the hectographed Old Believer publications stored in Scientific Research Department of Rare Books (the Book Museum) in Russian State Library. A brief description of the composition of the collection is presented, as well as the specifics of its formation (in the absolute majority such publications were received after the revolutionary events of 1917). The main sources of their receipt were the book collections of the most famous Old Believer community in Moscow (at the Rogozhsky cemetery), as well as the nationalized library of the Brotherhood of St. Peter the Metropolitan. For historians of the book, the thematic composition of the collection of Old Believer authors and writings is of interest.
Scientific Activity of Russian Libraries in the Field of Bibliography (Bibliographic Researches)
Authors: Levin Grigoriy L.
Published: March 2024

The historical process of separating bibliographic science from a single bibliography as a science is briefly examined. The role of domestic libraries and their employees in the development of bibliographic thought in the Soviet period and at present is revealed. It is noted that in the context of a reduction in the teaching of bibliographic disciplines in universities and the corresponding liquidation of special bibliographic departments, the center for conducting bibliographic research and specialized scientific events (conferences, seminars, methodological meetings etc.) is moving to libraries.
A compact, equality-based weighted residual formulation for periodic solutions of systems undergoing frictional occurrences.
Authors: Legrand Mathias , Pierre Christophe
Published: March 2024

A very compact weighted residual formulation is proposed for the construction of periodic solutions of oscillators subject to frictional occurrences. Coulomb's friction is commonly expressed as a differential inclusion which can be cast into the complementarity formalism. When targeting periodic solutions, existing algorithms rely on a procedure alternating between the frequency domain, where the dynamics is solved, and the time domain, where friction is dealt with. In contrast, the key idea of the present work is to express all governing equations including friction as equalities, which are then satisfied in a weak integral sense through a weighted residual formulation. The resulting algebraic nonlinear equations are solved numerically using an adapted trust region nonlinear solver and basic integral quadrature schemes. To increase efficiency, the Jacobian of the friction forces is calculated analytically in a piecewise linear fashion. The shape functions considered in this work are the classical Fourier functions. It is shown that periodic solutions with clear multiple sticking and sliding phases can be found with a high degree of accuracy. The equality-based formulation is shown to be effective and efficient, convergence being achieved in all cases considered with low computational cost, including for large numbers of harmonics. Importantly, this new friction formulation does not suffer from the typical limitations or hypotheses of existing frequency-time domain methods for non-smooth systems, such as regularization, penalization, or massless frictional interfaces.

В условиях глобализации и интенсификации научно-технического сотрудничества между странами актуализируется вопрос о необходимости качественного образования специалистов в сфере нефтегазовой промышленности. По данным Петербургского государственного горного университета, около 68% исследований в этой сфере публикуются на английском языке. В данной статье исследуется возможность применения нейронных технологий сравнительного перевода для улучшения уровня языковой подготовки студентов нефтегазовых вузов на базе русского и английского языков. Разработанная система на основе многослойных перцептронов и долгосрочной короткосрочной памяти (Long Short-Term Memory, LSTM) показала эффективность в определении семантических отношений между терминами в текстах нефтегазовой тематики, достигая точности до 94.7% на тестовой выборке из 800 документов. Эти данные предоставляют значительный потенциал для создания новых методик обучения, повышая уровень междисциплинарной компетентности будущих специалистов. Технологии нейронного сравнительного перевода — это тип моделей машинного обучения, которые помогают решать задачи межъязыкового перевода. Эти модели предварительно обучены и используют параллельные данные для предварительного обучения, что дает им возможность прогнозировать замаскированные слова на исходной и целевой стороне со ссылкой на контекст любой стороны параллельных данных.

In the context of globalization and intensification of scientific and technical cooperation between the countries, the issue of the need for high-quality education of specialists in the oil and gas industry is being actualized. According to the St. Petersburg State Mining University, about 68% of research in this field is published in English. This article examines the possibility of using neural technologies of comparative translation to improve the level of language training of students of oil and gas universities based on Russian and English. The developed system based on multilayer perceptrons and long-term short-Term Memory (LSTM) has shown efficiency in determining semantic relations between terms in oil and gas texts, achieving accuracy of up to 94.7% on a test sample of 800 documents. These data provide significant potential for the creation of new teaching methods, increasing the level of interdisciplinary competence of future specialists. Neural comparative translation technologies are a type of machine learning models that help solve problems of interlanguage translation. These models are pre-trained and use parallel data for pre-training, which gives them the ability to predict masked words on the source and target side with reference to the context of either side of the parallel data.

Terminal imido complexes, containing metal-nitrogen multiple bonds, have been widely used in organometallic chemistry and homogeneous catalysis. The role of terminal imido ligands span from reactive site to spectator motif, largely depending on the nature of the metal center and its specific coordination sphere. Aiming at identifying reactivity descriptors for M-N multiple bonds, we herein explore solid-state 15N NMR spectroscopy (ssNMR) on early-transition metal terminal imido complexes augmented by computational studies and show that the asymmetry parameter k, (skew, 1 ≥ k ≥ -1), readily available from experiments or calculations, is diagnostic for the reactivity of M-N multiple bonds in imido complexes. While inert imido ligands exhibit skew values (k) close to 1, highly reactive imido moieties display significantly lower skew values (k << 1) as found in metallocene or bis-imido complexes. Natural Chemical Shielding analysis shows that skew values away from 1 are associated with an asymmetric development of pi orbitals around the M-N multiple bond of the imido moiety, with a larger sp2-hybridized character for reactive nitrogen. Notably, this reactivity descriptor does not directly relate to the M-N-C bond angle, illustrating the shortcoming of evaluating hydridization from geometrical parameters alone. Overall, this descriptor enables to obtain direct experimental evidence for pi-loading effect seen in bis(imido) and related complexes, thus explaining their reactivity.
