The «elite–mass» dichotomy in the ideology of the non-systemic opposition of modern Russia
Authors:   Academy of Management of the Ministry of Internal Affairs of Russia, Kozyrev Maksim S. ,   Plekhanov Russian Economic University
Published: December 2023

The article aims to identify the features of the social opposition between the population and the nonsystemic opposition based on an analysis of the ideology of the latter. The methodological basis of the work was the proposition that a certain social position corresponds to certain points of view and type of thinking (total ideology). Therefore, similar ideological intentions of various groups of non-systemic opposition in relation to the described dichotomy leads to the idea that their social position is also similar. Apparently, these are groups of professional politicians seeking to occupy higher social positions or return to the ones they previously occupied. These groups can also be characterizsed by a high level of qualification resources, which makes it possible to formulate certain ideological constructs, a relatively high level of economic resource, which excludes from their discourse the problem of scarcity of material means of subsistence, inherent in the majority of the population of modern Russia, as well as social isolation, which does not allow them to articulate the interests of other groups to which they do not belong. This leads to the conclusion that the non-systemic opposition represents people from the urban intelligentsia, including the near-elitist intelligentsia, with inflated expectations of their social status. From «to have or to be» they choose the former. Despite their being in opposition, these groups do not seek to blow up or substantially reconstruct the existing social order. Their ideologies cannot be classified as utopias, and the limit of the aspirations of the non-systemic opposition is its own upward vertical social mobility.
The practices of human spatial existence in a post-conflict situation
Authors:   Ural Federal University named after the first President of Russia B.N. Yeltsin, Satybaldina Diana K.
Published: December 2023

This article attempts to develop understanding of human practices in a post-conflict situation within the framework of the spatially oriented approach. Traditional methods of understanding conflicts, such as trauma studies, focus on the psycho-emotional state of the participants in a conflict. Based on the works of A. Lefebvre, M. de Certeau and G. Bachelard, the author proposes to consider this problem in a manner of Philosophical Anthropology, which allows us to identify the relationship between the experience of a post-conflict situation and everyday space of the individual. Considering the spaces of a post-conflict situation as «non-places», and based on the theoretical approach of M. de Certeau, the author proposes several tactics for a person’s staying and adaptation to a post-conflict situation. The author believes that there are two main tactics of this kind: the «tactics of immobility» and the tactics of «temporary rootedness». «Immobility» is understood as an individual’s right not to act, as an opportunity while not to form but to comprehend the probabilities of constructing new spatial connections «here and now». In addition, «immobility» is considered by the author as an opportunity to move on to the next step — «temporary rootedness». Such rootedness is characterized by more stable boundaries and spatial practices that allow us to reproduce «home» practices, and thereby find psycho-emotional and even physiological stability in the new post-conflict everyday life. The possibility of reproducing elements of the old pre-conflict existence sets the prospect of existence in a new reality.

Published: December 2023

At the end of the 20th century, the demand for more efficient methods for solving large sparse unstructured linear systems of equations increased dramatically. Classical single-level methods had already reached their limits, and new hierarchical algorithms had to be developed to provide efficient solutions to even larger problems. Efficient numerical solution of large systems of discrete elliptic PDEs requires hierarchical algorithms that provide a fast reduction of both shortwave and longwave components in the error vector expansion. The breakthrough, and certainly one of the most important advances of the last three decades, was due to the multigrid principle. Any appropriate method works with a grid hierarchy specified a priori by coarsening a given sampling grid in a geometrically natural way (a "geometric" multigrid method). However, defining a natural hierarchy can become very difficult for very complex, unstructured meshes, if possible at all. The article proposes an algorithm for calculating the deformation that occurs under the action of a thermal expansion force in three-dimensional solid models based on a grid approximation of the problem by hexagonal 8-node cells. The operation of the algorithm is illustrated by solving three problems.

Solid solutions 0.65BiFeO3–0.35Ba1-xSrxTiO3 (0 ≤ x ≤ 1) with the compositions in the vicinity of the morphotropic phase boundary “rhombohedral-cubic” were synthesized by the Solid-state reaction method. The crystal structure and morphology of the ceramics 0.65BiFeO3–0.35Ba1-xSrxTiO3 were studied based on the data obtained by X-ray diffraction, scanning electron microscopy, Raman spectroscopy, as well as energy-dispersive X-ray spectroscopy methods. It was determined that the chemical substitution of barium ions with strontium ions leads to a decrease in the magnitude of rhombohedral distortions, while the unit cell parameters decrease in the whole substitution concentration range. The solid solutions with x ≥ 0.25 are characterized by a single-phase structural state with a cubic unit cell; the average crystallite size decreases with increase of the dopant ions. The results of the structural studies carried out using Raman spectroscopy indicate the presence of rhombohedral distortions in the structure of all studied compounds, which is caused by the presence of nanosized clusters with rhombohedral symmetry. The obtained results made it possible to determine the sequence of the changes occurred in the phase state and the unit cell parameters in the region of the morphotropic phase boundary “rhombohedral -pseudocubic”; the concentration intervals corresponding to the single-phase and two-phase structural states of the compounds were determined. The region of concentration stability of the polar rhombohedral phase was clarified using the structural data obtained by local and microscopic research methods.

Magnetoelectric (ME) composites can be useful due to their wide range of possible applications, especially as sensors of weak magnetic fields at room temperature for magnetocardiography and magnetoencephalography techniques in medical diagnostic equipment. In most works on the topic of ME composites, structures are tested in uniform magnetic fields; however, for practical application, a detailed consideration of the interaction with inhomogeneous magnetic fields (IMF) is necessary. In this work we made measurements of IMF with radial symmetry of individual thin wire with AC voltage with different placements of ME sensor. A ME self-biased structure b-LN/Ni/Metglas with a sensitivity to magnetic field of 120 V/T was created for IMF detection. The necessity of external biasing magnetic field is avoided by a nickel layer and its remanent magnetization. ME composite shows a non-zero ME coefficient of 0.24 V/(cm·Oe) in absence of DC external magnetic field. It is shown that output voltage amplitude from ME composite, which is located in AC IMF, is dependent from relative position of investigated sample and magnetic field lines. Maximum ME signal is obtained when long side of ME sample is perpendicular to the wire, and symmetry plane which divides the long side in two similar pieces contains an axis of the wire. In frequency range from 400 Hz to 1000 Hz in absence of vibrational and other noises a limit of detection has value of (2 ± 0.4) nT/Hz1/2.

Silicon-carbon films are of great interest as diamond-like materials combining unique properties – high hardness, adhesion to a wide class of materials, abrasion resistance, as well as chemical resistance, low coefficient of friction and biocompatibility. The presence of silicon in the composition makes it possible to significantly reduce the internal mechanical stresses in such coatings compared to diamond ones. In modern production, films have been used primarily as solid lubricants and protective coatings. There are a large number of methods for producing silicon-carbon films, the most widespread among which are various variants of vapor-phase chemical deposition. In this paper, a method for the synthesis of silicon-carbon films was proposed and tested, based on the use of a high-frequency inductor to produce a plasma of vapors of silicon-carbon liquid injected into the chamber from an external source. Pure silicon-carbon films with a carbon atom content with sp3-hybridized orbitals of 63–65 % were obtained on sitall substrates. The composition, surface roughness and coefficient of friction of unalloyed silicon-carbon films obtained by the proposed method were studied. The possibility of resistive switching in thin silicon carbon films in crossbar structures with metal electrodes was studied.

Charged domain walls (CDW) in ferroelectric materials are interesting from fundamental and applied points of view, since they have electrical properties different from bulk ones. At the microstructural level, CDW in ferroelectrics are two-dimensional defects that separate regions of the material with different directions of spontaneous polarization vectors. Compensation of the electric field of the bound ionic charge of the CDW by mobile carriers leads to the formation of extended narrow channels with increased conductivity in the original dielectric material. By controlling the position and angle of inclination of the CDW relative to the direction of spontaneous polarization, it is possible to change its conductivity in a wide range, which opens up broad prospects for creating memory devices, including for neuromorphic systems. The review presents the current state of research in the field of formation and application of CDW formed in single crystals of uniaxial ferroelectric lithium niobate (LiNbO3, LN) as resistive and memristive switching devices. The main methods for forming CDW in single crystals and thin films of LN are considered, and modern data on the electrophysical properties and methods for controlling the electrical conductivity of CDW are presented. The prospects for using CDW in memory devices with resistive and memristive switching are discussed.
OPTIMIZATION OF OPERATION MODES OF THE PLUNGER PUMP OF THE FORMATION PRESSURE MAINTENANCE SYSTEM

Published: December 2023

The efficiency of pumping equipment in the context of continuous growth in electricity prices is a priority for any oil and gas production department (OGPD). The pumping stations of the reservoir pressure maintenance system are the main consumers of electricity in the OGPD. The efficiency of pumping units, as a rule, is reduced primarily to the value of their efficiency, and the criterion for the efficiency of the injection system is usually the consumption of electrical energy per unit volume of pumped liquid. At the same time, they often focus only on maintaining high pump efficiency, which optimizes pump operation, but does not take into account the impact of collectors on electricity costs.Typically, the PPD pump station will inject service water into several directions. The purpose of the studies is to find optimal modes of pumping by pumps of a pump station in several directions, which ensure minimum electric power consumption for injection. The presented article presents the calculation of the cost of pumping by one plunger (volume) pump into two directions during laminar movement of liquid in the pipeline. Injection volumes for each area are specified. Three options are considered: separate injection in each direction (1), parallel injection in both directions simultaneously until the ordered volume is injected in one of the directions, after which this direction is blocked and injection in the other direction (2), and parallel injection in both directions simultaneously with «pressed» one direction, so that the injection of the ordered volumes is completed simultaneously (3).The performed calculations showed that the useful operation of the pump performed during simultaneous pumping of some volumes of liquid (modes 2 and 3) in two different directions of the same system is the same and significantly less compared to the operation of the pump performed to fill one of these directions during separate pumping (mode 1). The maximum effect is achieved with equal injection volumes in each direction and the same reservoirs. In this case, the useful operation of the pump for simultaneous injection (mode 2 and 3) is half as much as for separate injection (mode 1).
ABOUT SOME PROBLEMS OF WATERFLOODING IN CARBONATE RESERVOIRS
Authors: Svalov A.M.
Published: December 2023

The features of waterflooding of carbonate (fractured-porous) rocks, caused by the interaction of the system of fractures with the matrix (blocks) of the rock, are considered. It is shown that the slower propagation of the pressure pulse in the rock matrix in comparison with the propagation of this pulse along the fracture system of the formation leads to compression of the rock blocks in the near-wellbore zone of the injection well, as a result of which stress concentration occurs at the ends of vertical fractures, which increases the likelihood of these fractures growing into the roof of the productive formation. It is shown that in order to prevent the development of this process, the growth rate of water injection pressure should be limited in accordance with the time of liquid pressure equalization in the pore space of the rock matrix and in the fracture system. When developing production wells drilled in fractured porous media, in order to prevent the development of the process of closing fractures in the bottomhole zones of these wells, the drawdown reduction rate must also be limited in a similar way. It is noted that when applying technologies for non-stationary flooding of productive reservoirs, the main factor determining their effectiveness is the change in the direction of filtration flows in the reservoir. This leads to the activation of filtration processes in the stagnant zones of the formation and the intensification of the processes of capillary impregnation of low-permeability interlayers with water from more flooded highpermeability interlayers.At the same time, it is important to take into account that when changing the direction of filtration flows at a late stage of development of carbonate reservoirs, in order to prevent reimpregnation of hydrophobic rock blocks with oil, it is more expedient to change the operating modes of production rather than injection wells. It is shown that water flooding of hydrophobic carbonate reservoirs results in incomplete water displacement of oil as a wetting phase from rock blocks. To reduce the residual oil saturation of rock blocks, it is advisable to increase the displacement pressure gradient in the reservoir in combination with a change in the direction of filtration flows in it.

The efficiency of oil recovery from oil-bearing reservoirs by modern, Abstract. industrially developed development methods in most oil-producing countries today is considered unsatisfactory, and the final oil recovery of reservoirs in various countries and regions averages from 25 to 40 %. For example, in Latin America and Southeast Asia, average oil recovery is 24–27 %, in Iran — 16–17 %, in the USA, Canada and Saudi Arabia — 33–37 %, in the CIS countries and Russia — up to 40 %, depending on the structure of oil reserves and the development methods used [1].Therefore, the task of managing the productivity of oil and gas reservoirs remains relevant at present.The article discusses a special technology for the use of gamma and electro-logging as part of the Perfobur technical system (hereinafter referred to as pyrolysis oil). These geophysical methods of investigation, at the end of drilling radial channels over a small diameter and radius of curvature, performed with trajectory control, make it possible to prove that drilling was carried out in a given reservoir, and provide more detailed information about its productivity.One of the areas of use of pyrolysis oil is enhanced oil recovery, intensification of inflow, restoration of normal operation of wells stopped or hindered due to falling at the bottom of oil field equipment, blocking or contamination of the perforation zone, including during initial penetration [2–5].Complex geological conditions are noted, such as high reservoir fragmentation, heterogeneity of the carbonate reservoir, fracturing, large lateral permeability variability, high oil viscosity and presence of washed zones, caverns after salt-acid treatment (SW) with subsequent steam injection. Under such conditions, it is difficult to develop a field, new well logging methods are required, as well as high-quality logging to determine saturated interbeds. Effective development of the field requires the determination of the current reservoir saturation with higher accuracy, which will help the subsoil user to better develop the field, eliminate stimulation of watered beds, and carry out better and more selective intensification of interbeds. It should be noted that the presence of a steel column practically eliminates the possibility of using electrical logging methods. Therefore, it is recommended to use such methods in an open hole. Drilling of radial channels using the Perfobur technology allows electro-logging with a special tool due to the possibility of repeated entries into the drilled channels [2–5].

The paper presents a unique method for studying mudstone samples using an independent triaxial compression unit developed at the Department of Oil and Gas Well Drilling, Samara State Technical University. Drilling directional and horizontal wells has difficulties associated with wellbore stability. Stability is directly determined by the strength and deformation characteristics of the rocks, and also takes into account anisotropy, bottomhole pressure and wellbore configuration. In this regard, there are emergency situations at the rig: scree and collapse of the walls of wells in the intervals of unstable rocks. The purpose of the study is to study the core properties to prevent these complications during the design phase. Analysis of rock compression test methods was performed. The method of study is physical modeling of mountain stress at the plant for triaxial compression. The work presents a phased study plan. Analysis of the problem of microcracking of mudstones was also carried out. Based on the design characteristics of plant classes for independent triaxial loading, the installation of the second class with multi-stop systems was chosen. At this stage, the installation is equipped with software. Experiments were carried out according to the first loading program, that is, first the core sample was uniformly compressed along all three axes in one position, and then in a turned position on the 90º. Pressure versus displacement plots were obtained. After processing the results, you can find the Poisson ratio, Young’s modulus, and shear modulus, as well as determine anisotropy. In the future, it is planned to conduct experiments on core saturation.

The oil and gas refining industry in Russia and other countries is faced with the challenge of searching for new highly active catalytic systems and innovative methods for processing various types of petroleum feedstocks, including heavy petroleum feedstocks. One of the main tasks of this industry is to increase the depth of processing of petroleum raw materials to obtain more valuable petrochemical products.The purpose of the work is to study the dependence of the thermal destruction of heavy petroleum feedstock – heavy vacuum gas oil from the AVT-5 unit of PJSC «Bashneft-Novoil» in the presence of a new metal-complex catalytic system, where the active component is a chlorferrate complex (NaFeCl4) in an amount of 10 %, deposited on a carrier representing is a deeply decationized Ymmm zeolite of the acidic form (H-form), when varying process conditions, temperature in the range from 450 to 550 °C and volumetric feed rate of raw materials – 1,75–2,50 h-1. The physicochemical characteristics of the metal complex catalyst – 10 % NaFeCl4 / HYmmm zeolite were studied: characteristics of the porous structure, study of the phase composition, study of the morphology of the surfaces of catalytic systems.During experimental studies, it was established that the 10 % NaFeCl4/HYmmm zeolite catalytic system has a highly developed surface with a pore distribution of micro-, meso- and macropore sizes (total pore volume ~ 0,64 cm3/g); preserves the degree of crystallinity of the lattices relative to the original support Ymmm. It has been established that thermocatalytic destruction of heavy vacuum gas oil in the presence of a metal complex catalyst leads to its deep and selective conversion. The data obtained indicate that in the studied modes of the thermal destruction process, it is possible to achieve the formation of unsaturated olefinic hydrocarbons of the composition C2-C4 ~ 20 % wt., gasoline fraction ~ 45 % wt., total light ~ 68 % wt.

Dilated cardiomyopathy (DCM) is a disease of the heart muscle resulting in decreased myocardial function and is the second most common myopathy in canine. Previously, canine dilated cardiomyopathy was considered to be an inherited disease among large and giant breeds, however, recent reports suggest a possible link between certain grain-free diets and this condition. Several investigations into the incidence of this condition in relationship to grain-free diet consumption have been conducted in recent years. The most recent research shows a static overall trend in the incidence of DCM despite a five-fold increase in the sales of grain-free pet foods. Inadequate intake of protein, taurine, and specific sulfur-containing amino acids may have a potential role in the development of DCM, as these nutrients are crucial for cardiac muscle development and function. However, significant research remains to be done on the topic to discern any potential definitive causation.

A certain percentage of individuals in any society have disabilities, which can be further complicated by the presence of disease. This can create additional burdens in their lives, making it essential to provide them with adequate attention and satisfactory care to alleviate their difficulties. Good nutrition, both in terms of quantity and quality, is an important factor in human life. This article serves as a reminder of the basics of healthy nutrition for all individuals while also highlighting the challenges related to nutrition for those with disabilities and disease conditions. Research has shown that people with disabilities and chronic diseases are often malnourished. For patients who have difficulty with swallowing and/or have gastrointestinal disorders, nutrition support therapy in the form of enteral or parenteral nutrition must be employed. This article includes a brief description of the tubes that are used in artificial feeding. Decisions on tube feeding should be made carefully, taking into consideration the quality of life on a case-by-case basis. Oral nutritional supplements can be used to provide all essential nutrients based on the type of disability and medical condition. There is a need for more research concerning the area of nutrition for individuals with disabilities, and specialized training of involved healthcare professionals is a necessity. From a public health perspective, raising awareness about all types of disabilities among families, educators, healthcare providers, and the public should be a priority.

The circumstances of the coronavirus disease-2019 (COVID-19) pandemic and the resulting confinement of persons culminated in political unrest, demonstrations for social justice, and increases in crime, including intimate partner violence. The pandemic gave intimate partner abusers free reign to monitor the activities, movements, and communications of domestic abuse survivors, restricting access to planning and implementing an escape route. This resulted in the need for psychologists to provide psychological services, some of which were restricted by the limitations of the pandemic. With psychologists providing this assistance, it appears clear that they are in a unique position to inform policy, political decisions, and social justice based on their training, clinical practice, and expertise in human behavior and human suffering. This paper addresses the need for psychologists as social advocates, arguing that they occupy a vital position in both treatment and research that enables them to represent those affected by intimate partner violence (IPV), as well as inform legislation on this issue.

These systems enable such individuals to secure appropriate compensation and lead fulfilling lives within their communities. Objective This stakeholder engagement process explores the lived experiences of individuals with disabilities and their journey through the claims processes, understanding their concerns and expectations. Results A total of 152 participants participated in the seminar. Thirty-nine participants with extensive experience in medical disability assessment and the claims process were purposefully surveyed, and in-depth interviews were conducted. Several themes emerged from the interview: awareness and education, the legal and judicial system and processes, expert opinion, and reports. Conclusion The findings concluded that expert opinion and report emerged as a critical theme, with participants stressing the need for guidelines, professionalism, and accreditation for expert witnesses. Establishing a multidisciplinary regulatory body to design and develop an educational program for court experts is suggested, as is creating and maintaining a public register of court experts. Such measures will promote transparency, accountability, and quality in expert testimony and reporting

Ascosphaera apis is the sole source of the invasive mycosis known as “chalkbrood disease”, which only affects honeybee larvae. Around 5-37% less honey is produced globally as a result of the illness, and 80% of broods perish. Because of the disease’s current severity, more pesticides are used, and colonies are frequently transported over great distances, which may have created new opportunities for Ascosphaera apis infection. There are signs that the incidence of this disease, which is now widespread worldwide, may be increasing. It is also highly unlikely that Ascosphaera apis will ever be completely eradicated due to its widespread distribution throughout the world, the fact that it can persist for more than 15-years in soil near infected apiaries, and the fact that viable spores can be found in stored honey, pollen, pollen capsules and tablets, used hive components, and used beekeeping tools and equipment. Safe control of the disease has been noted to be challenging, despite the fact that management techniques, medications, and the adoption of particular chalkbrood-resistant bees have all been demonstrated to have some benefits thus far. Thus, current research for a better understanding of chalkbrood will focus on genetic engineering for better fungus manipulation, molecular investigation of Ascosphaera apis pathogenesis pathways, and the potential identification of strategies to break the pathway through the identification of responsible genes for its pathogenesis. Some researchers have noted the prevalence of chalkbrood disease and linked chalkbrood diseases to bee colony losses and decreased productivity in affected bee colonies.

Bu çalışmanın ana amacı; sporcu ve sedanter bireylerde Wingate anaerobik güç testi (WAnT) performansının beş saniyelik segmentler ekseninde incelenmesidir. Çalışmanın ikincil amacı ise fiziksel özellikler ile WAnT performansı arasındaki ilişkiyi ortaya koymaktır. Çalışmaya iyi antrene durumdaki 13 erkek sporcu (Ort. yaş: 23,31 ± 2,06 yıl) ve 13 sağlıklı sedanter (Ort. yaş: 22,84 ± 1,99 yıl) gönüllü olarak katılmıştır. Öncelikle katılımcıların demografik ve antropometrik ölçüm aşaması tamamlanmıştır. Daha sonra katılımcılar, tek seanslık laboratuvar ölçümünde bir bisiklet ergometresi (Monark Wingate Ergometer model 834E) aracılığıyla 30 saniyelik WAnT (WAnT-30) protokolünü tamamlamıştır. Test yükü, vücut ağırlığının %7,5’i olarak belirlenmiştir. Test sonucunda ergometre yazılımından elde edilen WAnT-30 zirve güç (ZG) ve toplam altı segmentten oluşan beş saniyelik ortalama güç (OG) çıktıları kaydedilmiştir. Sporcular, WAnT-30 ZG ve tüm beş saniyelik segmentlere ait OG çıktılarında sedanterlere göre daha yüksek değerlere sahipti (p<0,001). Sporcularda WAnT-30 ZG değeri ile tüm beş saniyelik OG çıktıları arasında pozitif ilişki olduğu belirlenirken (p<0,05; r = 0,594- 0,970), sedanterlerde ise bu ilişki 3. segmentten sonra kaybolmuştur. Basit doğrusal regresyon sonuçlarına göre sporcularda boy uzunluğu ve vücut ağırlığı, WAnT-30 performansının en iyi belirteçleri olarak tespit edilmiştir (R2 = 0,362- 0,689 ve R2 = 0,457- 0,590 sırasıyla). Sonuç olarak, sporcuların WAnT-30’a ait tüm segmentlerde sedanter bireylere göre daha yüksek güç çıktısına sahip olduğu belirlenmiştir. Ayrıca sporcularda tam eforlu bir anaerobik performansın fiziksel özelliklerden etkilenebileceği görülmüştür. Sonraki çalışmalarda spesifik spor dallarından katılımcılarda farklı segment aralıkları kullanılarak anaerobik performansın gelişmiş bir değerlendirmesi yapılabilir.

El profesorado debe tener la competencia de reflexionar sobre su propia práctica. El enfoque ontosemiótico ofrece como herramienta para este propósito los “Criterios de Idoneidad Didáctica”. Los objetivos de esta investigación son refinar los indicadores de la Idoneidad Epistémica (IE) y profundizar en la dimensión epistémica del conocimiento meta didáctico-matemático de los profesores de matemáticas de secundaria en formación inicial. Para ello se han examinado las investigaciones sobre el objeto función en la educación secundaria. De forma mixta, se ha analizado, en 119 “Trabajos Finales del Máster (TFM) de Formación del Profesorado de Matemáticas de Secundaria (Catalunya, España)” sobre funciones, la reflexión que hacen los futuros profesores sobre su docencia, sobre la IE. A partir de estos estudios se realiza el diseño de la adecuación de la IE para analizar el objeto matemático función. Finalmente se reanalizan los TFM con esta nueva pauta y se constata que sus reflexiones presentan importantes carencias que podrían influir en la calidad de sus procesos de instrucción. Se concluye que, si se dotara al profesorado de una pauta especializada que les facilite considerar todos los significados, representaciones y procesos involucrados en la complejidad de las funciones, así como las prácticas matemáticas en las que estos emergen, mejoraría la calidad del diseño, implementación y reflexión sobre sus procesos de instrucción.

This article discusses the methodology and results of molecular dynamics simulation of the diffusion of carbon nanotubes in water. The main goals of this work were to study diffusion longitudinal to an axis of the nanotube and transverse to this axis and determine the velocity autocorrelation functions and diffusion coefficients in these directions. The interaction of water molecules with each other was described by the Lennard-Jones potential, and that of carbon nanotube molecules by the AIREBO potential. The diameters of the nanotubes were 1.15 and 1.44 nanometers, their length varied from 5 to 15 nanometers. The number of water molecules in the simulation cell reached one hundred thousand. It is shown that the nanotube center of mass velocity autocorrelation function in the longitudinal direction decays much more slowly than in the transverse direction. The corresponding values of the diffusion coefficients differ by a factor of 2–4; this diffe¬rence increases with increasing ratio of the nanotube length to its diameter. The directionally averaged diffusion coefficients of flexible nanotubes decrease with increasing nanotube length. Its values exceed the corresponding values for their solid analogues. A nonmonotonic decay of the nanotubes center of mass velocity autocorrelation function was discovered. The characteristic time between the maxima of this function coincides with the period of bending vibrations of the nanotube.

This work is devoted to developing an algorithm for trajectory filtering in multi-position passive radar systems. This paper presents an algorithm that uses the flight altitude in the geodetic coordinate system as an additional observation. In practice, this information can be known if the radio radiation source uses an onboard IFF responder in A/C mode. In this case, the flight altitude can be decoded and used as an additional observation. In this paper, a simulation was performed to compare the effectiveness of the proposed algorithm with the standard one based on the Extended Kalman filter without using additional observation. Comparison of the algorithms was also carried out on experimental data. It is shown that the use of a priori information about the geode¬tic altitude of the flight as additional observations of the algorithm allows not only to increase the accuracy of two-dimensional coordinate estimation (up to 2.5 times), but also to increase the stability of trajectory tracking in comparison with the algorithm that does not take this information into account.
J. G. Hamann’s Conversion as the Key to His Work

Published: December 2023

The article deals with the mechanism of the religious conversion of the 18th century Königsberg writer J.G. Hamann as well as the infl uence of this event on his subsequent literary activity characterized by an insightful critique of the Enlightenment project. In his autobiography not geared toward the public, this conversion has features of a typical Pietist conversion with its peculiar language as well as normative accents on feelings along with the lowered role of reason. His debut work “Socratic Memorabilia”, however, which was addressed to I. Kant and I.K. Berens, served as vindication of his new “Weltanschauung”, and enables one to interpret his conversion as a transition to a new conceptual scheme with its own distinct interpretation of texts, ideas, and events. Theological-philosophical foundations of Hamann’s conversion have greater signifi cance than its psychological aspects. Within this framework, the former life is then viewed from a different perspective. However, it is the text and the author behind the text (rather than internal feeling of the heart) that is primary to Hamann. This text presupposes subsequent authorship of Hamann himself. Thus, the London conversion experience of Hamann may not be reduced to ecstasy, elimination of cognitive and rational capacities, but rather viewed as “metanoia”, a change of thinking, way of life, and worldview. From this perspective it is more appropriate to view the ensuing philosophical career of Hamann as activity in a different framework rather than conceptualization of personal experience of conversion. While his efforts were directed at a variety of subjects (theology and philosophy of history, aesthetics, philosophy of language, correlation of faith and reason, critique of political basis of the Enlightenment), the very thrust of his thinking was governed by a conceptual scheme, which in turn also implied a different lifestyle (attitude to professional activity, family, and marriage), incongruent with the conventional notions of the time.
