Amur State University (Russian: Аму́рский госуда́рственный университе́т) is a university in Blagoveshchensk, Amur Oblast, Russia. is closely associated with the history of the Amur Region. Blagoveshchensk Technological Institute was founded on the basis of Blagoveshchensk Technical Faculty in 1975. At that moment it was the first institute of light industry in the Far East. In 1992 Blagoveshchensk Technological Institute was renamed into Blagoveshchensk Polytechnical Institute. Two years later the Polytechnical Institute developed into a full-fledged multidisciplinary university; the Amur State University..
This study examines PbZrO3 ceramics synthesized from nanodispersed PbO and ZrO2 powders with BaTiO3 nanoparticles with sizes of 50, 200, and 400 nm. The incorporation of barium titanate (BaTiO3) nanoparticles into lead zirconate (PbZrO3) ceramics expanded the stability range of the ferroelectric (FE) phase, extending it down to room temperature. As BaTiO3 content increased, the peak of dielectric permittivity shifted toward lower temperatures, while ε′ values rose significantly, reaching a maximum at 10 wt.
The demarcation between religion and quasi-religion is a widely debated issue in the humanities and theology. Clearly, a definitive solution to this problem is difficult to achieve due to the complex morphology of religion, the presence of transitional forms between religious and non-religious phenomena, the dynamics of the religious landscape, and a number of other objective factors. At the subjective level, the problem is complicated by the presence of numerous concepts (pseudo-religion, ersatz religion, and others) that are poorly distinguished from the concept of quasi-religion. This article presents definitions of religion and quasireligion. Religion is a spiritual formation that includes ideas, actions, and social groups based on the belief in the existence of an otherworldly world that has power over this world. The essence of religion is the orientation of consciousness and activity toward the otherworldly world. This intentionality distinguishes religion from science, art, politics, and other cultural formations focused on objects and goals within the confines of human existence. A quasi-religion is a religion-like configuration of ideas and practices that syncretically combines religious and non-religious components, with the latter being dominant. The components of religion included in a quasi-religion do not define the essence and content of the system, being secondary and serving a subsidiary function. Non-religious components – political, social, ecological, ethnic, scientific, ethical, psychological, and other – are dominant in religion-like systems. The typology of quasi-religions includes political, ethnic, ecological, psychological, therapeutic, scientific, psychic, and other types of quasi-religions.
Relevance. Phytoremediation is the most relevant and popular method of soil purification from pollution. However, in addition to the ability of plants to accumulate metals, it is necessary to take into account their adaptability to growing conditions. Therefore, information on native plant species with wide adaptability is important. Screening of plants in metal-bearing areas will help identify plant species that are optimal for phytoremediation. Aim. To study the accumulation capacity of plants growing on the territory of the mining enterprise JSC Pokrovsky Rudnik (Pioner gold deposit, Amur Region) in relation to polluting elements. Methods. The elemental composition of soils, grounds, plants and the content of mobile forms of soils were determined using atomic emission and mass spectral methods. Results. The authors have identified the following pollutant elements: As, S, Mn, Cr, Co, Ni, Cu, Zn, Mo, Cd, Sb, Te, W, Pb, Bi, requiring closer attention in the territory of the mining enterprise of JSC Pokrovsky Rudnik. The predominant pollutant is As. The ability of native plant species to enrichment was studied using accumulation factors and the actual biogeochemical mobility of elements. As a result of the correlation analysis between the content of elements in plant samples and their mobile forms in soils, it was found that plants growing on technogenically transformed soils have barrier mechanisms for the absorption of As, Sb, Pb, Bi, Co, Cr, Ni and Cu. A number of plant species were identified as potential remediants of contaminated soils in the territory of the mining complex, due to their ability to accumulate toxic elements without damaging their normal physiological state, adaptation to the harsh climate of the region, and altered soil conditions.

The article synthesizes a system of combined control of a class of nonlinear-nonstationary multi-mode plants operating under conditions of structural-parametric uncertainty and different types of delays (neutral delay and state delay). A procedure for complete (structural and parametric) synthesis of a control system is proposed. Firstly, based on the hyperstability criterion, $\boldsymbol{L}$-dissipativity conditions, as well as the use of filtercorrectors (setting and output) and an implicit reference model, a structural synthesis of the combined control system is carried out. Structural synthesis includes four key stages: presentation of a mathematical model of the control system in deviations, solution of two positivity problems, and verification of the fulfillment of control purposes. Secondly, with the help of a genetic algorithm, automatic selection of the coefficients of the developed control system is performed by minimizing the criterion of the generalized work - parametric synthesis. The efficiency of the synthesized control system is demonstrated at the simulation stage in the Matlab development environment, Simulink package.
The current paper investigates L1-induced interference patterns in manifestation of unstressed vowels in the Russian speech of a female speaker of the Ust-Nyukzha local Evenki accent. The subject pronounced words containing unstressed allophones expressed in spelling by letters “е”, “а”/“я” and “о”. The material was processed using auditory and acoustic analyses. It was found that due to the difference between Russian and Evenki phonological systems expressed in vowel harmony and weakly-centralizing stress in the latter, there was the absence of standard vowel reduction that triggered the realization of wrong allophones and the absence of standard phoneme changes or wrong phoneme changes. 38% of unstressed vowels demonstrated the absence of phoneme /e/ reduction in pretonic and post-tonic positions. When proceeded by soft consonants, in 63% of all unstressed positions, phoneme /ɑ/, instead of standard /i/ substitute, lacked reduction displaying the features of stressed /ɑ/ after soft consonants. When preceded by /ʧʲ/, /ʃʲ:/, /j/, unstressed vowels displayed the phoneme /e/ pattern instead of the standard /i/ pattern accounting for 13% of all unstressed instances. After hard consonants, 82% of first pretonic vowels, due to the lack of quality reduction, displayed [ɑ] allophone characteristic for stressed position instead of the standard reduced [ʌ]. There were very few instances (0.05%) of the absence of phoneme /o/ reduction. In all other instances its quality was reduced following the standard pattern that resulted in the standard /ɑ/ substitute. The obtained results demonstrate interference manifesting itself for two out of the three unstressed vowels in separate words.
