Historiosophical Problems in Russian Thought in the Modern Time
Authors:   Francysk Skaryna Gomel State University, Koren’ Elena V.
Published: June 2023

The article deals with the historiosophical problems of Russian thought in the Modern time. The historiosophical problems of Russian thought were determined by the peculiarities of spiritual and socio-political life, the development of national and civil consciousness of society, the formation of the intelligentsia. The major historiosophical problems of Russian thought since the XIX century have been the reflection on the fate and role of Russia in the global historical process; conceptualization of the meaning of history; analysis of social development options; the definition of progress criteria; the clarification of the role of an individual and people in history, understanding of the meaning of human existence. A number of historiosophical issues were identified in ideological searches of earlier times. Historiosophical ideas also influenced the development of historical science in Russia. The history of philosophy was interconnected with ontology and anthropology, gravitating towards metahistory. One of the most relevant problems for the Russian historiosophy was the meaning of history, which attracted the attention of historians, philosophers and other cultural leaders, in the context of the essence, content, criteria, driving forces of historical development; specifics of historical knowledge; political and moral significance of historical memory. The problem of the meaning of history was often revealed in moral and religious contexts, in connection with spiritual and moral problems of the meaning of human life. In the works of Russian thinkers, the remarkable ideas were expressed about socio-anthropological and moral meaning of history, which retain their significance to modern philosophical and historical research, to the spiritual and value-based self-determination of an individual and society.
Defense of Dissertations by Nikolai Il’ich Pokrovskii at Leningrad University
Authors:   Chelyabinsk State University, Alevras Natalia N.
Published: June 2023

This article is a discussion of the career path of N. I. Pokrovskii. The author attempts to uncover the key points of his biography and research career. Both of his defense procedures that took place in 1938–1939 are examples of the revival of the pre-revolutionary dissertation culture implemented through the practicing of the legal framework of its Soviet counterpart. The article focuses on the procedure and progress of the defense of the historian’s doctorate dissertation. The availability of the transcript enables the author to reveal the principles, style, atmosphere, and ideological components of this academic event typical of the early Soviet dissertation culture. The author highlights the specifics of the selection of opponents, the defense procedure and academic audit organization as well as the ensuing discussion. The opponents included well-known researchers from St Petersburg, I. Yu. Krachkovskii, an Arabist scholar acting as the candidate’s promoter, and B. D. Grekov and S. N. Valk, Doctors of history who were not authorities on the problems covered in the dissertation and treated the candidate with caution. I. P. Petrushevskii, an Orientalist historian, played a special role: he was an opponent during Pokrovskii’s candidate thesis defense and an unofficial expert during his doctoral defense debate. The debate in question involved the members of the Board of the Historical Faculty and the ‘public’ and demonstrated ambivalent attitudes towards the candidate’s position. The article attempts to understand the critical perception of Pokrovskii’s concepts and the impact of the political and ideological atmosphere in the pre-war USSR on the defense procedure and the historian’s life.
Russian America and its Problems in Contemporary National Works of Economists
Authors:   Peter the Great St Petersburg Polytechnic University, Grinev Andrei V.
Published: June 2023

The article critically examines the publications of modern Russian economists on the history of the former Russian colonies in the New World, sold in 1867 to the United States and subsequently forming the territory of the state of Alaska. Paradoxically, economists tend to mainly examine historical problems of Russian America, while some historians research economy, although everything should be just the opposite. The monitoring of scholarship conducted by the author reveals about a dozen works of professional economists — Candidates and Doctors of Sciences — who devoted their works (in whole or in part) to certain problems of Russian America: the earliest work is dated by 2011, and the most recent articles — by 2021. The depressingly low academic level of the vast majority of the analyzed works should be pointed out with regret. The fact is that Russian economists, for some unclear reason, almost completely ignore a wide range of published documentary sources, not to mention archival materials. The latter, if they are used, are not directly related to the history of Russian colonies in the New World. In the same way, national economists stubbornly avoid getting acquainted with the current Russian historiography about the past of Russian America and do not use more or less modern foreign scientific literature about it at all. Instead of academic works, economists often turn to non-scientific publications (including writings on alternative history) and Internet sites with highly questionable content. The natural result is a large number of errors, inaccuracies and incorrect conclusions, which are sometimes supplemented by negligently prepared bibliography and lack of elementary publication culture: almost all national economists economize on references/footnotes in their works: it is often completely impossible to understand where this or that information comes from. Thus, there is an imitation of scholarly activity and all sorts of dilettantism instead of real useful research on the history and economy of Russian America.
The Russian-Chinese Borderland in the Late Imperial Period in the Revision of Trade and Economic Relations
Authors:   St. Petersburg State University, Yanchenko Denis G.
Published: June 2023

The article based on the analysis of modern Russian historiography, archival materials, and press information characterizes a number of problems of economic policy in the Russian-Chinese borderland from 1880–1890 until the crisis in relations between the two powers in 1911. The methods of the 19th century were becoming less and less effective as the economy of the Qing Empire was being put on new capitalist “tracks”. Materials of periodicals, documents of personal origin received by governmental chanceries of Russia allow to reveal patterns of social thought of the turn of the 19th–20th centuries, describing the eastern lines of internal and foreign policy. The article outlines the opinions of the involved Russian regional population and the administration on trade and economic relations. The principles of the Treaty of Saint Petersburg and trade rules of 1881 did not stand the test of time. The Russian population in Eastern Turkestan, Mongolia, and later in the alienation zone of the Chinese Eastern Railway faced numerous problems related to property rights, illegal expropriation, barriers to commerce from the residents and the Chinese Qing authorities who saw in Russia a threat to their territory and even to the existence of the Qing dynasty. Foreign invasion into Manchzhuria, the construction of Russian settlements and cities in Chinese land, and then Russia’s defeat in the war with Japan forced the authorities of the two powers to look for new approaches to resolving trade and economic conflicts.
Political Portrait of Brezhnev
Authors:   St. Petersburg State University, Puchenkov Alexander S.
Published: June 2023

The article analyzes the features of the era of L. I. Brezhnev and its perceptions. The author presents his views on the political portrait of the Soviet leader. The article considers distinctive characteristics and stereotypical features of the image of the long-term leader of the Soviet state formed in the national and foreign historiography. The article indicates the key events and phenomena related to the foreign and domestic policy of the USSR under Brezhnev and describes the specific aspects of his managerial style. The author focuses on the details of the conspiracy to remove N. S. Khrushchev from power, and specifically point out that it was L. I. Brezhnev who headed this conspiracy, and not M. A. Suslov and A. N. Shelepin, as it is indicated in some research papers on the problem. The article also specifically examines the achievements of the foreign policy of the era of “détente”, the role of L. I. Brezhnev in the successes of the policy of those years, the model of his behavior in relations with foreign leaders, such as R. Nixon, J. Ford, V. Brandt, and others. The research is based on the testimonies of people who worked closely with L. I. Brezhnev and those who were in his inner circle. According to the author, L. I. Brezhnev was ready to retire at the end of the 1970s, but members of the Politburo insisted that he should keep his post. Brezhnev did not manage to survive as a politician; his death remained practically unnoticed by the Soviet people.
Names of colour in V.Nabokov’s bilingual worldview (based on the original and self-translated texts of the novel Lolita)
Authors:   Kuban State University in Slavyansk-on-Kuban, Bakumenko Olga N.
Published: June 2023

The article is devoted to the current problem of studying bilingual authors’ idiolects in colour aspect. This research aims to identify the features of Vladimir Nabokov’s lingua-colour worldview associated with the use of English and Russian in self-translation. Lists of colouremes of the original and translated Lolita are made; their part-of-speech facet is analyzed; dominant coloronyms are identified and compared; structural peculiarities of the selected colours in both lists are studied. The novelty of the work lies in the creation of English and Russian lexicons and frequency dictionaries of representatives of Nabokov’s color worldview, which gives objective data about the linguistic personality basing on idiolect. Along with quantitative method, the work uses the method of systematic scientific description, via which the multidimensional systematization of empirical material is conducted and the comparative method implemented in observation, comparison and interpretation techniques for the received language data. The article notes both common and specific features in the two color lexicons. With a comparable number of English and Russian colouremes, the translation language is more coloristic. Part-of-speech differences of colours are noted. In complete lists chromatic designations predominate, they are more frequent in Russian. Among the dominants achromatic colors outweigh, English achromatisms prevail. Numerous hapaxes and complex coloremes, rarely equivalent, contribute to the palette diversity. The main causes of inconsistencies are identified. The author comes to the conclusion that the ways of lexicalizing the color perceptions of the bilingual writer-translator are modified when switching to the target language that indicates differences in Nabokov’s worldview.

Authors:   Pavlov First St. Petersburg State Medical University, Yashin Sergei , Shubik Yuri ,   St. Petersburg State University
Published: June 2023

Atrial fibrillation is the most common supraventricular tachycardia, the incidence of which increases with age. This arrhythmia is the consequenсe of multiple cardiac and noncardiac pathology. The most significant side effects of atrial fibrillation are thromboembolic complications. It is generally accepted that the source of these embolisms is a thrombus in the left atrial appendage. However, the risk of thromboembolism also occurs after the onset of atrial rhythm, which can lead to a more complex hemostasis mechanism in this disease. There is no unambiguous definition of the relationship between structural and functional changes in the atria and atrial fibrillation, which manifests itself in the appearance of treatment. Essential methods of catheter operations in patients with atrial fibrillation do not take into account the peculiarities of the rhythm mechanism, which has an influence on the treatment’s results. The first part of the review reflects the anatomy, histology, and physiology of atria, their main cellular elements, and electrophysiological features. The main experimental and clinical models of arrhythmia are described; as factors provoking atrial fibrillation and mechanisms of its stabilization. The analysis of electrophysiological and structural remodeling. The concepts of atriopathy and atrial cardiomyopathy are discussed, and classification is given. The mechanisms of hemostasis disorders and possible directions of correction are presented.

Experimental study on the dissipation performance of supersaturated total dissolved gas in microbubble treatment
Authors: Ou Yangming , Li Zhenjun , Li Ran , Feng Jingjie , Faisal Shah
Published: June 2023

The production of total dissolved gas (TDG) supersaturation resulting from dam discharges has been identified as a causative factor for gas bubble disease (GBD) or mass mortality in fish. In this study, the mitigation solution for fish refuge in supersaturated TDG water was explored by using microbubbles generated by aeration to enhance supersaturated TDG dissipation. The effects of various aeration factors (aeration intensity, water depth, and aerator size) on the dissipation processes of supersaturated TDG were quantitatively investigated through a series of tests conducted in a static aeration column. The results indicated that the dissipation rates of supersaturated TDG increased as a power function with the factors of aeration intensity and aerator size and decreased as a power function with increasing water depth. A universal prediction model for the dissipation rate of supersaturated TDG in the aeration system was developed based on the dimensional analysis of the comprehensive elements, and the parameters in the model were determined using experimental data. The outcomes of this study can furnish an important theoretical foundation and scientific guidance for the utilization of aeration as a measure to alleviate the adverse impacts of supersaturated TDG on fish.

Published: June 2023

Research on knowledge regarding tooth avulsion and replantation among children and adolescents is still scarce. Objective: This cross-sectional study aimed to evaluate the knowledge about tooth avulsion and replantation and their association with independent variables among 7th-grade students in public schools. Material and methods: Data collection on the knowledge regarding tooth avulsion and replantation (nine questions) and sociodemographic profile was performed through semi-structured and self-administered questionnaires. The presence of trauma in permanent incisors of students (n=251) was obtained in a clinical examination performed by a calibrated examiner in Sertaozinho, Sao Paulo, Brazil. After a descriptive data analysis, association and multiple logistic regression tests were applied at a significance level of 5%. Results: Most of the students were female (61.4%), were residents in suburban areas (89.6%) and did not present dental trauma (87.7%). Students answered correct 42.2% of the questions. The variable “last visit to the dentist” was the only one that showed a statistically significant association with knowledge about tooth avulsion and replantation in the bivariate analysis (p = 0.007) and the logistic regression (p = 0.031). Conclusion: The level of knowledge was low, and the students whose last visit to the dentist was two years or longer showed a greater chance of having less knowledge about tooth avulsion and replantation. Clinical Significance: During routine dental visits, the dental team should educate patients about the procedures to manage different situations of dental trauma.

Authors: kumar Satish , Srivastava Pratima , Mujwar Somdutt , Gupta Sumeet
Published: June 2023

Background:

Rheumatoid arthritis is a progressive disease of human joints characterized by severe pain, stiffness, and tissue damage at the local site. Bone and cartilaginous tissue damage at the synovial joints is initiated by the production of autoantibody induced by inflammatory signaling through cytokines.

Objective:

This study aimed to evaluate the efficacy of Garcinia travancorica against acute and chronic inflammation in a rat model after designing the ligand library and target identification using computational analysis.

Methods:

Acute inflammation was induced by carrageen, and chronic inflammation was induced by Freund’s complete adjuvant in the plantar surface of the rats. The petroleum ether, ethanolic, and aqueous extracts in three divided doses (75 mg/kg, 150 mg/kg, and 300 mg/kg) were administered orally. Diclofenac sodium (10 mg/kg), prednisolone (5 mg/kg), and methotrexate (0.5 mg/kg) were used as standard. Various parameters were evaluated, and statistical significance between means was analyzed using one-way ANOVA, followed by Dunnett’s multiple range test.

Results:

Docking-based in-silico screening of the ligand library has revealed the potential of Polyanxanthone-C as an anti-rheumatoid agent, which is supposed to deliver its therapeutic effect by synergistic targeting of interleukin-1, interleukin-6, and tumor necrosis factor receptor type-1.

Conclusion:

This plant has the potential to be used in the treatment of arthritis-related disorders.
Calcium Folate for Reducing the Side Effects of Low-dose Methotrexate in
Rheumatoid Arthritis: A Case Report
Authors: Liu Renzhu , Yan Qingzi , Hu Yixiang , Liu Xiang
Published: June 2023

Introduction:

We reported a patient with rheumatoid arthritis who received chronic
methotrexate (MTX) therapy and experienced several adverse reactions like hemocytopenia and
renal impairment. Under the monitoring of the therapeutic drug concentration, calcium folate and
other measures were used to accelerate methotrexate excretion and eliminate adverse reactions.

Case Presentation:

A 66-year-old man with rheumatoid arthritis received MTX and developed adverse
effects of bone marrow suppression, like pancytopenia. He had a black stool, and he tested
positive for occult blood, which was considered gastrointestinal bleeding. The blood MTX concentration
reached 4.07 μmol/L, and leucovorin was administered to rescue the patient's life. Besides,
hydration and alkaline urine were applied to quickly clear methotrexate inside the body.

Conclusion:

Low-dose MTX has fewer adverse reactions but may cause bone marrow suppression-
related side effects. Blood concentration monitoring can be used to guide the rescue of MTX
poisoning.

Recent Patents on Thermal Characteristic Analysis and Modeling of
Machine Tools
Authors: Li Zhaolong , Du Junming
Published: June 2023

Modern machining machines are becoming more sophisticated and automated, but the
problems of thermal deformation caused by machining have also come to the fore. CNC machine
tools are used in high-speed, high-feed rate machining conditions, so the impact of thermal deformation
factors will lead to a more prominent loss of accuracy. In this context, the design and
manufacture of future CNC machine tools need to take further account of the errors caused by
thermal deformation and the accompanying loss of accuracy. The principle of thermal characterisation
and thermal error modeling of machine tools is to measure and reasonably analyse the machine
tool at different temperature points and make corrections to the analysis data in order to get
a value as close as possible to the real value and improve machining accuracy. Several representative
patents and studies on thermal characterisation and thermal error modeling of machine
tools at home and abroad are reviewed. This study presents a selection and summary of a large
number of recent patents and studies on machine tool thermal characterisation and thermal error
modeling, focusing on the selection of the machine tool thermal error measurement point area,
thermal error modeling methods, spindle thermal displacement compensation, and other aspects,
and discusses the future trends in the mainstream methods for reducing the thermal error of machine
tools. The analysis and modeling of thermal errors in machine tools have an integral influence
on further improvements in machining accuracy and efficiency in the future.

Published: June 2023

Background:

The control of the Covid-19 epidemic depends on designing a novel, effec-tive vaccine against it. Currently, available vaccines cannot provide complete protection against various mutants of Covid-19.

Objective:

The present investigation aimed to design a new multi-epitope vaccine by using in silico tools.

Methods:

In the present study, the spike-glycoprotein was targeted, desirably stimulating both B and T-cell lymphocytes, providing effective and safe responses in the host immune system. The de-sired vaccine has been found to possess 448 amino acids of spike glycoprotein. The prognosticated epitopes included 10 CTL, 4 linear B-cells, and 14 HTL, including the 128 amino acid sequence of 50S ribosomal protein adjuvant joined by GPGPG and AAY linkers on the N terminus of linear B-cell, HTL, and CTL epitopes, and the C-terminal joined with HHHHHH (6HIS) linker, indicating stability for vaccine structure.

Results:

The molecular docking has revealed the protein-protein restricting communication between the immunization construct and the TLR-3-resistant receptor. The vaccine has been developed through selected epitopes, an adjuvant, and an additional epitope. Docking assays with toll-like re-ceptor 3 have been run on a three-dimensional structural model of the vaccine to gauge its immuno-logical potency. Our findings support the hypothesis that our vaccination will activate TLR-mediated downstream immune pathways by aggressively interacting with the innate receptor.

Conclusion:

The results suggest that the proposed chimeric peptide could initiate an efficient and safe immune response against Covid-19. The proposed vaccine has been proven safe in all critical parameters.

BRUSHLESS DIRECT CURRENT (BLDC) MOTOR SPEED CONTROL USING FIELD ORIENTED CONTROL (FOC) METHOD
Authors: Nurdamayanti Nurdamayanti , Sartika Linda , Prasetia Abdul Muis
Published: June 2023

ABSTRACTBrushless DC motors or commonly known as BLDC motors are starting to be widely used in the automotive and industrial fields compared to three-phase induction motors. This is because the advantages of BLDC motors are high efficiency, large torque, and easy maintenance. Some drive systems that use BLDC motors require a constant motor speed. However, when the drive system is given more load, the speed will decrease. Therefore, we need a motor speed regulation so that the speed becomes constant even though it is given an overload. There are many ways to adjust the speed of a BLDC motor, one of which is using the Field Oriented Control method because it can adjust the field current and armature current separately. From the simulation results, the speed of the BLDC motor using the FOC method in the loaded condition, showed a better response by producing a steady state of 1494 rpm, a rise time of 0.5192 s, a settling time of 0.6362 s while not being given a load, a steady state of 1504 rpm and, a rise time of 0.533 s and a settling time of 0.64 s.ABSTRAKMotor Brushless DC atau biasa dikenal dengan motor BLDC mulai banyak digunakan pada bidang otomotif dan industri dibandingkan dengan motor induksi tiga fasa. Hal ini disebabkan karena kelebihan dari motor BLDC adalah memiliki efisiensi tinggi, torsi yang besar, dan perawatan mudah. Beberapa sistem penggerak yang menggunakan motor BLDC membutuhkan kecepatan motor yang konstan. Akan tetapi sistem penggerak tersebut ketika diberi beban lebih maka kecepatan akan menurun. Oleh karena itu dibutuhkan suatu pengaturan kecepatan motor agar kecepatan menjadi konstan walaupun diberi beban lebih. Banyak cara untuk mengatur kecepatan motor BLDC salah satunya adalah menggunakan metode Field Oriented Control karena dapat mengatur antara arus medan dan arus jangkar secara terpisah. Dari hasil simulasi didapatkan kecepatan motor BLDC menggunakan metode FOC pada kondisi berbeban, menunjukkan respon yang lebih baik dengan menghasilkan steady state yaitu 1494 rpm, rise time 0.5192 s, settling time 0.6362 s sedangkan tidak diberi beban didapatkan steady state sebesar 1504 rpm dan, rise time sebesar 0,533 s dan settling time sebesar 0,64 s.

The motivational effects of working from home for Information Technology employees can vary greatly depending on the individual and the situation. The main motivators tend to be the increased flexibility and autonomy that comes with working from home, as well as the potential for increased productivity and efficiency when there are no distractions from the office. Additionally, having the ability to work remotely can help to reduce stress levels, as employees don’t have to worry about commuting or dealing with distractions in the workplace. For those who are parents, the ability to work from home can provide more time to spend with family, which can be a major source of motivation. The motivational effects of working from home for Information Technology employees can vary. The employees may find it liberating to work from home, while others may find it isolating and have difficulty staying motivated. However, there are some common practices that can help to promote motivation for IT employees working from home. These include setting realistic goals, providing feedback, recognizing employee achievements, and encouraging collaboration. Additionally, managers should ensure that employees have the necessary resources to do their jobs effectively, such as access to secure network connections and adequate communication tools. Finally, employers should ensure that employees have a good work-life balance, and make sure to provide support and guidance when needed.
Improving an Electronic Health Record–Based Clinical Prediction Model Under Label Deficiency: Network-Based Generative Adversarial Semisupervised Approach (Preprint)

Published: June 2023

BACKGROUND

Observational biomedical studies facilitate a new strategy for large-scale electronic health record (EHR) utilization to support precision medicine. However, data label inaccessibility is an increasingly important issue in clinical prediction, despite the use of synthetic and semisupervised learning from data. Little research has aimed to uncover the underlying graphical structure of EHRs.

OBJECTIVE

A network-based generative adversarial semisupervised method is proposed. The objective is to train clinical prediction models on label-deficient EHRs to achieve comparable learning performance to supervised methods.

METHODS

Three public data sets and one colorectal cancer data set gathered from the Second Affiliated Hospital of Zhejiang University were selected as benchmarks. The proposed models were trained on 5% to 25% labeled data and evaluated on classification metrics against conventional semisupervised and supervised methods. The data quality, model security, and memory scalability were also evaluated.

RESULTS

The proposed method for semisupervised classification outperforms related semisupervised methods under the same setup, with the average area under the receiver operating characteristics curve (AUC) reaching 0.945, 0.673, 0.611, and 0.588 for the four data sets, respectively, followed by graph-based semisupervised learning (0.450, 0.454, 0.425, and 0.5676, respectively) and label propagation (0.475,0.344, 0.440, and 0.477, respectively). The average classification AUCs with 10% labeled data were 0.929, 0.719, 0.652, and 0.650, respectively, comparable to that of the supervised learning methods logistic regression (0.601, 0.670, 0.731, and 0.710, respectively), support vector machines (0.733, 0.720, 0.720, and 0.721, respectively), and random forests (0.982, 0.750, 0.758, and 0.740, respectively). The concerns regarding the secondary use of data and data security are alleviated by realistic data synthesis and robust privacy preservation.

CONCLUSIONS

Training clinical prediction models on label-deficient EHRs is indispensable in data-driven research. The proposed method has great potential to exploit the intrinsic structure of EHRs and achieve comparable learning performance to supervised methods.

Introduction. The publication highlights efforts undertaken by Siberia Department of the Imperial Russian Geographical Society (since 1851 — Siberia Department, since 1877 — Eastern Siberia Department) to explore the ethnography of the Mongolic peoples. Despite the available related publications are numerous enough, the topic remains somewhat understudied. Since the creation of Siberia Department, its members had made a great breakthrough in the exploration of Siberia, the latter’s natives, their ethnic histories, ethnogeneses, lifestyles, and cultures. It would be impossible to cover the complete scope of works performed by associates of Siberia Department for comprehensive insights into the ethnography of Mongols. Goals. So, the paper attempts a review of scientific endeavors by Siberia Department of the Imperial Russian Geographical Society aimed at ethnographic descriptions of the Mongolic peoples. The Department also contributed a lot to the ethnographic study of the peoples inhabiting regions neighboring with Russia, including the ones populated by Mongolic ethnic groups. The article identifies key directions of research work, significances of writings by the Department’s members for ethnographic research of Mongols, mentions important periods in the history of the Department, and shows who played critical roles in establishing trends within the exploration agenda. Methods. The study rests on the system of principles, approaches and methods inherent to historical science, including both general (analysis, synthesis, description, etc.) and special (descriptive, comparative-historical, etc.) ones. Conclusions. Despite the difficulties faced by researchers affiliated to Eastern Siberia Department when it came to investigate household life and ethnic culture, their activities yielded essential scientific findings, facilitated further historical and ethnographic analyses of the Mongolic peoples. The original artifacts collected by the Department’s members would lay bases for museum collections, their studies still remaining as unique and required by present-day scholars.
