History of the komi-permyak writing system: a comparative overview of alphabets from the late 19th to the mid-20th century
type: item
description: This article presents a comparative historical analysis of alphabets developed for the Komi-Permyak language from the 19th century until the adoption of the modern Cyrillic standard in 1938. The relevance of the study stems from the lack of comprehensive works that systematize the numerous and often uncommon variants of its writing system in the scholarly literature. The aim of the work is to conduct a comparative analysis of these systems based on the criteria of adequacy in representing Komi-Permyak sounds, as well as the practicality and consistency of graphic solutions. The research material comprises alphabets from key monuments of Komi-Permyak writing: N. Rogov’s dictionary (1869), a series of primers (1894–1908), V. Molodtsov’s original Cyrillic alphabet (1918), Latin-based projects (1924, 1932), and projects for a Cyrillic alphabet from 1937. To ensure an objective comparison, the article first provides a detailed overview of the phonetic system of the Permic languages, including consonantism, vocalism, and main dialectal differences. The study identifies the main trends in the evolution of Komi-Permyak writing: from early projects that were guided by the rules of Russian orthography and often ignoring the language’s specificity, through strictly phonemic systems (the Savvaitov-Rogov, Molodtsov, and Latinized alphabets), to the modern alphabet, which represents a compromise between the phonemic principle and an orientation towards the Russian graphic base. The article contributes to the systematization of knowledge on the history of KomiPermyak writing and assesses the effectiveness of the considered alphabetic systems from linguistic and practical points of view.

New data on the craniology of the population of the Perm Kama region of the modern era
type: item
description: The article publishes primary craniometric data of small samples from the territory of the Perm Kama region which date back to the Modern era. Three groups from the cemeteries of Solikamsk, Perm (Egoshikhinsky cooper smelter) and Pyskor are compared. After the morphological characterization, a canonical analysis was carried out. The research led to assumption regarding the genetic links between the Solikamsk population of the XVII – XVIII centuries and certain medieval groups in the region. The conclusions known from the literature concerning the complexity of the formation of the anthropological composition in the Perm Kama region have been confirmed. The unique nature of the population formation issue in the city of Perm as the new industrial center of the XVIII century is becoming obvious.

title: Sosnowski’s hogweed (Heraculum sosnowskyi manden) as an object of ecological and legal regulation: a comprehensive analysis of invasion, control methods and the evolution of the legislative framework on the example of the Perm Region
description: Sosnowsky’s hogweed (Heracleum sosnowskyi Manden) is a striking example of the transformation of an introduced species into a large-scale environmental and social threat requiring a comprehensive legal response. The article provides a comprehensive analysis of the problem, based on a synthesis of data on the biological and ecological characteristics of the plant, agricultural control practices, and a detailed study of the regulatory framework. Special emphasis is placed on the evolution of legislative regulation of invasive species control in the Russian Federation – from fragmented regional initiatives to the formation of a unified federal legal framework. The history of the species’ introduction, the mechanisms of its invasive success, and the multifaceted damage, including reduced biodiversity, economic losses, and a direct threat to public health, are examined in detail. Control methods (mechanical, agrotechnical, chemical) are described, with an assessment of their effectiveness, resource intensity, and environmental risks. The central focus of the study is an analysis of legislative measures: tracing the dynamics from a legal vacuum, through active regional rulemaking (using the examples of Moscow, Leningrad, Tver, Kaluga Oblasts and Perm Krai), to systemic changes at the federal level initiated by Federal Law No. 294-FZ of July 31, 2025. An overview of sanctions established in various constituent entities of the Russian Federation and administrative procedures is provided. Using the example of Perm Krai, the model of escalation of management measures is analyzed in detail – from the introduction of a “High Alert” regime and the establishment of administrative liability to the extension of the legislation’s scope to all lands of municipalities and the organization of planned interdepartmental work. It is concluded that effective suppression of invasion is possible only if scientifically based control methods are integrated into the strict framework of continuo…

Analysis of the current state of knowledge of the causes of spontaneous combustion of sulfide ores
type: item
description: This paper analyzes the current state of knowledge of the spontaneous combustion of sulfide ores. The main factors affecting the heating of sulfide ores are presented, including the excess of heat release from oxidation processes over heat loss to the environment. The primary factor determining the level of heat loss is the geometric size of the waste heap. It is noted that little-studied factors accelerating sulfide ore oxidation include temperature, fractional and mineralogical composition of sulfide ores, as well as the presence of ammonium nitrate-based explosives. A review of international experimental research and methods for determining the susceptibility of sulfide ores to spontaneous heating and combustion is presented. It is noted that existing methods and mathematical models of waste heaps do not allow for the reliable determination of the conditions for spontaneous heating and combustion of sulfide ores. Based on this, further research directions have been identified to determine the conditions for spontaneous heating and combustion of sulfide ores in underground workings and waste heaps of ore stored on the surface.

Features of hydrocycloning technology when changing the sludge processing method
type: item
description: A method has been developed for processing stockpiled (flotation) sludge for the purpose to extract precious metals. One of the main stages is the process of three-phase hydrocycloning of calcined sludge (cinders) using primary and secondary hydrocyclones at each stage. The ground cinder is pulped and fed to a series of hydrocyclones with taper angles of 10, 7 and 5 degrees. These hydrocyclones desludge the ground cinders and produce sands for centrifugal separation, yielding a concentrate consisting of a mixture of intermetallic compounds (Pd, Pt, Ag, Cu, Sn, Pb) and intermetallic compounds (Fe, Cr, and Ni). Magnetic separation allows for the separation of these intermetallic compounds. The result of using three-phase hydrocycloning was a 10-fold reduction in the volume of ground cinder, which, in turn, made it possible to reduce the scale of equipment in centrifugal separation operations for sand by 10 times.

Low-temperature large-scale modeling of air flow stability in an inclined mine working with a heat source
type: item
description: An analysis was carried out on the possibilities of large-scale modeling of downward airflow in inclined mine workings with a heat source within the parametric range of airflow instability. It was established that accurately reproducing model similarity to reality in this range is only possible within the framework of the Froude scaling rules with identical air temperature, which at the fire source reaches 1500 K or more. Since achieving such air heating under laboratory conditions is problematic, an attempt was made to obtain approximate low-temperature scaling relations based on estimated calculations targeting a threefold reduction in temperature with a tenfold reduction in geometric dimensions. The obtained relations were verified through numerical modeling of the thermal plug effect in the SolidWorks software suite, as well as on a laboratory simulation stand. The relative error in determining the overturning point of airflow due to thermal depression in model and full scale was 2%. Both methods of modeling the thermal plug effect showed the same dynamic scenario of airflow direction change via instability, in which the flow overturns gradually, forming large-scale convective vortices and multidirectional vertical velocity stratification across the cross-section.

Smart-watches for medicine. Review
type: item
description: Modern wearable devices have evolved from simple pedometers to complex multi-sensor systems providing continuous and non-invasive monitoring of a wide range of physiological parameters. This transition is transforming consumer gadgets into tools for preventive medicine and biomedical research. This analytical review focuses on the physical principles underlying the recording of physiological parameters and their potential application for health monitoring. The key technology of the smart-watches is the method of optical photoplethysmography which allows for the recording the modulation of reflected scattered light flux by pulsating blood flow. Smart-watch functionality, recently expanded to include electrocardiogram measurements, offers additional opportunities for medical application of these gadgets. The most anticipated features include arterial blood pressure and biochemical monitoring via smart-watches. The second part of the review provides a detailed analysis of the physiological characteristics that can be derived from the physical signals recorded by smart-watches. The third part outlines medical applications, and the forth describes the diagnostic value of the recorded physiological parameters, as well as the possibility of potential using of the obtained data in medical practice.

Anyushkar settlement: tasks and prospects of new research
type: item
description: Anyushkar settlement is one of the most famous and best–excavated archaeological sites in the Perm Region and the only one whose name is known thanks to the traditions of the Permian Komi. It rises on the shore of the Kama reservoir near the village of Kylasovo, and is a very picturesque and iconic place. It is an ancient settlement that occupied an advantageous strategic position near the confluence of the river. During its heyday, the village of Inva in Kama was a Bulgarian trade and craft trading post. The presence of a Muslim burial ground testifies to the residence of the Bulgars here. A variety of craft workshops, dwellings, and defensive structures have been studied at the settlement. During the excavations, rich and expressive materials were collected, testifying to the peculiarities of the way of life, economic and industrial activities of the inhabitants of the settlement, and their cultural and economic ties. However, the results of its research have received little publication coverage, and the materials obtained have remained unpublished. Since 2024, the settlement has been the object of research by the Institute of Humanitarian Studies, Ural Branch of the Russian Academy of Sciences. Firstly, the monument requires urgent rescue operations, as it is rapidly being destroyed by the reservoir. Secondly, it requires clarifying some of the conclusions made by previous researchers, taking into account new knowledge and techniques, using an interdisciplinary approach. The continuation of the research is also due to the fact that the technology of medieval crafts remains a priority area in the research of archaeologists of the Institute of Humanitarian Studies, Ural Branch of the Russian Academy of Sciences and Anyushkar can provide a lot of additional data for the development of this topic. The ultimate goal is to collect disparate data on previous studies, supplement them with new information to prepare a large-scale publication, which this landmark archaeolo…

Passive vibration damping of a plate made of functionally graded material
type: item
description: The use of functionally graded materials in smart systems based on piezoelectric elements provides a number of additional advantages over homogeneous metals and alloys. Smooth variation of the mechanical properties of a structure along one or more directions makes it possible to optimize its dynamic parameters at the design stage, within the given constraints on the dimensions and mass of the structure. In this paper, the finite element method was used to study the free and forced steady-state harmonic vibration of a rectangular functionally graded plate with a piezoelectric element connected to an external electrical RL circuit. The examples analyze the influence of the volume fraction index of the functionally graded material on the electromechanical coupling coefficient, natural frequencies and vibration amplitude. The possibility of varying them within limits sufficient for safe operation of the structure in the vicinity of the initial resonance is demonstrated.

Modeling aerodynamic characteristics of a wing airfoil using artificial neural networks
type: item
description: The paper considers the application of artificial neural networks to solve the direct and inverse aerodynamic modeling problems using the example of a two-dimensional NACA2415 wing profile. Based on the numerical solution of the steady-state Navier–Stokes equations, a training dataset is formed, which includes aerodynamic lift and drag coefficients for various values of the geometric parameters and angle of attack. A neural network with two hidden layers of 10 neurons and a sigmoid activation function is built and trained on datasets with regular and random distribution of parameters. The feasibility of solving the inverse problem of recovering the geometric parameters of an airfoil and angle of attack from given aerodynamic coefficients with an error of no more than 5% is demonstrated. The results confirm the effectiveness of neural networks for modeling and inverse design of aerodynamic profiles.

The use of by-products of animal husbandry and K-Mg ore processing for potato mini-tubers production a greenhouse
type: item
description: The article discusses the use of by-products of processing K-Mg ores (sludge) and animal husbandry (dry chicken manure) for potato mini-tubers production in greenhouse conditions. The changes in the agrochemical parameters of the substrate (peat), the content of trace elements in potato leaves and the productivity of mini-tubers of the Julia and Grand potato varieties were studied depending on the doses and ratios of by-products. The higher rate of consumption of nutrients from the substrate led to degradation of peat agrochemical parameters for the early variety Julia relatively to the medium-ripened Grand variety on the 45th day after planting. The use of sludge led to increase of water-soluble salts concentration and chloride content in peat by 2.6 g/l and 0.32%, respectively (LSD05=0.6 g/l and 0.12%, respectively). The highest content of mobile forms of phosphorus and potassium, as well as nitrate nitrogen, was obtained by the combined application of sludge and dry manure. The total mass of mini-tubers for the Grand variety was 156.1 g, for the Julia variety 144.5 g (the difference is 11.6 g with LSD05=9.7 g). The average number of mini-tubers formed was 8.6 pieces per Julia variety and 7.1 pieces per Grand variety (LSD05=1.2 pieces). The use of sludge had the greatest impact on the total weight and number of mini-tubers. The content of trace elements in potato leaves had complex patterns of distribution according to experimental variants. Reliable inverse correlations were established between the total mass of mini-tubers and Co content (r=-0.82), as well as between the quantity of mini-tubers and the Mo content (r=-0.72). No negative effect of increased chloride concentration in peat on the productivity of mini-tubers was observed.

description: The rapidly growing threat of microbial resistance has driven increased interest in the research and development of new antimicrobial agents from various sources. Consequently, increasing attention is being paid to methods for screening and assessing antimicrobial activity. Some testing methods, such as disk diffusion, agar well diffusion, and broth dilution, are well-known and widely used. However, methods for assessing antibiofilm activity and identifying and inhibiting dormant forms have not been widely adopted. Methods such as flow cytometry, fluorescence, and bioluminescence provide rapid results for assessing the activity of antimicrobial compounds and understanding their impact on cell viability and damage, but require specialized equipment and subsequent assessment of the reproducibility and standardization. This article provides an overview of bacterial susceptibility testing methods used to analyze new compounds with antibacterial potential. It presents widely known and laboratory-developed methods for detecting antibacterial activity. These include methods for identifying antagonist strains that produce antimicrobial compounds, quantitative assessment of antibacterial activity, identification of dormant forms of bacteria, inhibition of bacterial adhesion on a solid surface, the effect of antibacterial compounds on the biofilm formation and the destruction of mature biofilms, and studying the mechanism of action, as well as enhancing antimicrobial properties.

Statistical aspects of dayly fluctuations of water quality indicators (on the example of the Kama reservoir)
type: item
description: Water bodies located in zones of active technogenesis are characterized by significant time variability of hydrochemical indicators of water quality. When conducting traditional monitoring of water bodies with water sampling using standard bathometers, the values of monitored water quality indicators are determined, as a rule, with a characteristic time averaging of ~10 seconds. The problem arises, however, as to how do these indicators relate to their average daily values? What should be the minimum averaging period in order to obtain objective average daily values of the considered water quality indicators? The paper considers the application of the analysis of variance to study every-second and five-minute observations of water conductivity and turbidity for two sections of the Kama Reservoir: the Chusovskoy Ples area of Perm and the Berezniki area. It has been demonstrated that water quality monitoring in the Perm area of the Kama Reservoir should be based on the evaluation of integral sampling methods with a time averaging scale of at least 10 minutes. At the same time, with regard to the Kama reservoir near Berezniki, the need for integrated sampling with averaging of at least 1.5 minutes is confirmed

Linguistic corpus and experimental study of axiological categories in the mentality of Russians and Chinese (based on the corpora of the modern Chinese language)
type: item
description: Values as the foundation of human existence influence our thoughts thus invisibly setting the direction of life. Different cultures reflect values in their own national way. GOOD and EVIL are the main concepts in the category of value, the main standard for judging behavior in general, the main means of national emotional evaluative judgments and important polar concepts that represent value and anti-value, respectively. The purpose of the article is to identify and analyze the semantic components of the value aspect of the lexemes GOOD / 善 and EVIL / 恶, as well as to model the semantic structures of these lexemes. The material for this study were fragments from the «Dictionary of Russian Mentality» and two national corpora of the Chinese language. The article identifies the value features of the meaning of the lexemes GOOD / 善 and EVIL / 恶: in Russian and Chinese society as aesthetic and ethical categories, i.e. moral principles underlying human behavior. The antithesis GOOD – EVIL in Russian society is explained from the point of view of the philosophical category of the unity of opposites; in Chinese society – from the point of view of the theory of «moral language».

Study of the interrelation between abrasive wear resistance of cast polyurethane-type elastomers and their structural and physical-mechanical features
type: item
description: Several series of cast polyurethane and polyurethane-urea elastomers, potentially promising for use in aggressive abrasive environments, have been synthesized. The relationships between the degree of abrasive wear under dry friction conditions and such factors as the chemical structure of the materials under study, their phase state, ambient humidity, and the content of friction modifiers have been studied. An assessment was made of the possibility of predicting the abrasive wear of the materials under study using their physical and mechanical characteristics obtained during stretching. The features of the mechanism of changing the parameters of the spatial network of polyurethane and polyurethane-urea elastomers during abrasive wear were revealed. It was established that the dependence of the degree of abrasive wear of the studied elastomers on the content of hard segments in the polymer chain had the form of a function with an extremum. Studying the effect of the content of friction modifiers on the abrasive wear of the specified elastomers made it possible to determine the optimal level of such additives in known casting compositions used in industry.

On the predictability of magnetic field inversion within a simple dynamic model
type: item
description: A viscous generalization of the Rikitake two-disk dynamo model, known as the simplest dynamic model of random reversals of the geomagnetic field, is considered. A systematic study of the emerging solution modes in the parameter space (the degree of ohmic dissipation and the ratio of the moments of forces rotating the disks) has been carried out under a fixed magnetic Prandtl number Pm=10-6, acceptable for the liquid core of the Earth. It is shown that there is a narrow domain in the parameter space in which the rare-reversal chaos, characterized by very long chrones (time intervals during which the sign of the magnetic field is preserved), within which the solution is quasi-stable, and the field fluctuations are characterized by a small amplitude and an extremely slow growth rate. Some regularity of the evolution of field disturbances within a single chron has been revealed, which makes it possible to predict the time of the next magnetic field reversal.

To the language of ancient inhabitants of Perm
type: item
description: This review article looks into some aspects of the origin, development and current state of the Komi-Perm language. The paper touches upon the origin of the ethnonym Komi-Perm, shows the sources of penetration of foreign language words into the language under study. The importance of imagery words in labeling sound and associative forms has been determined. The article briefly notes the ways of realizing the representations of space and time by grammatical means of the language: developed case and postpositional systems, grammatical forms of the past tense. The paper presents an attempt to explain how the Komi-Perm language has adapted to the absence of rather ordinary abstract words. Imagery and symbolism actively realized by highly motivated lexemes are demonstrated on the image of a fly (gut), when set expressions and words are perceived by all KomiPerm language speakers clearly semantically without any comments and clarifications. The development of the modern Komi-Perm language is connected with the tendencies of word reduction, further development of the case system, changes in grammatical forms of adverbs and so on.
