Abstract
Aim. To determine the main factors of inadequate fat diet (IAFD) and indicate the ways of their change.
Methods. Analysis and generalization of existing scientific literature data and the results of our own research.
Results. The following factors of IAFD have been identified:
1) excess fat in the diet;
2) an excess of palmitic acid in dietary fats;
3) an excess of linoleic acid in dietary fats;
4) consumption of thermoperoxide fats;
5) deficiency of ω-3 polyunsaturated fatty acids (PUFA).
Conclusion. IAFD is a cause of metabolic and neuropsychiatric disorders underlying non-communicable diseases.

Archaeological Work at the Kotelnich Hillfort in 2023
No full textThe article describes the preliminary results of rescue archaeological work at one of the oldest Russian sites in the Vyatka region — the Kotelnich hillfort, carried out in 2023 during the gasification project along Staroe Gorodishche Street. Seven small excavations were laid and explored on the site with a total area of 13.15 m, in which, after a complete study of the cultural layer, gas equipment was installed to lay a gas pipeline to private households located on the monument. A general description of the excavations is given. Despite the limited area of the work, new information was obtained about the stratigraphy of this rather complex site. The set of finds is characterized. The rescue work reflected different periods in the history of the early core of the town of Kotelnich — the Kotelnich hillfort. In one of the excavations, a section of a wet cultural layer was discovered. In another excavation, a section of the Kotelnich burial ground of the 16th–18th centuries was discovered and described. A preliminary description of the ceramic complex was separately conducted, and the results of the technical and typological analysis were presented. The collection of ceramic ware is both the most widespread and the most important source for the description of the urban cultural layer, but since the early 1990s, this category of finds has not received due attention in publications dedicated to Russian sites of the Vyatka region. A rather archaic technology for the production of ceramic ware, typical of this site, is preliminarily shown. Certainly, the research at the Kotelnich hillfort represents scientific novelty and interest for further research
Structural properties of concave cylindrical brushes interacting with free chains
No full textWe present a self-consistent field theoretical study of the microstructure of concave cylindrical brushes as a function of the cylinder radius, grafting density, grafted chain length, and the solvent quality. We show that the results for the radial monomer density profile and the distribution of the free ends are in good agreement with the corresponding molecular dynamics results. Part of the investigation is focused on the conformational behavior of a free macromolecule in a cylindrical brush. A central result is the observed non-monotonous variation of the size of a free chain in a brush-coated tube when the tube radius is systematically changed. An interpretation of this behavior which differs qualitatively from that of a polymer in cylindric confinement is suggested in terms of scaling theory and rationalized by considering the overlap between the free polymer and the grafted chains as a function of the tube radius. © 2011 The Royal Society of Chemistry.Adiga SP, 2005, NANO LETT, V5, P2509, DOI 10.1021-nl051843x; Adiga SP, 2007, MACROMOLECULES, V40, P1342, DOI 10.1021-ma0617522; Advincula R.

О составных формулах для математического ожидания функционалов отрешения уравнения Ито в гильбертовом пространстве
No full textThis article is devoted to constructing composite approximate formulas for calculation of mathematical expectation of nonlinear functionals of solution of the linear Ito equation in Hilbert space with additive noise. As the leading process, the Wiener process taking values in Hilbert space is examined. The formulas are a sum of the approximations of the nonlinear functionals obtained by expanding the leading random process into a series of independent Gaussian random variables and correcting approximating functional quadrature formulas that ensure an approximate accuracy of compound formulas for third-order polynomials. As a test example, the application of the obtained formulas to the case of a one-dimensional wave equation with a leading Wiener process indexed by spatial and temporal variables is considered. This article continues the research begun in [1].The problem is motivated by the necessity to calculate the nonlinear functionals of solution of stochastic partial differential equations. Approximate evaluation of mathematical expectation of stochastic equations with a leading random process indexed only by the time variable is considered in [2–11]. Stochastic partial equations in various interpretations are considered [12–16]. The present article uses the approach given in [12].Данная работа посвящена построению составных приближенных формул для вычисления математического ожидания нелинейных функционалов от решения линейного уравнения Ито в гильбертовом пространстве с аддитивным шумом. В качестве ведущего процесса рассматривается винеровский процесс, принимающий значения в гильбертовом пространстве. Формулы представляют собой сумму аппроксимаций нелинейных функционалов, полученных разложением ведущего случайного процесса в ряд независимых гауссовских случайных величин, и корректирующих аппроксимирующих функциональных квадратурных формул, обеспечивающих точность составных формул для полиномов третьего порядка. В качестве тестового примера рассмотрено применение полученных формул к случаю одномерного по пространственной переменной волнового уравнения с ведущим винеровским процессом, индексированным пространственной и временной переменными

Professional development of teachers on the basis of a digital educational platform: Challenges to the expert community
No full textThe relevance of the research lies in the fact that teachers often fail to cope with the tasks of digital communication and their own learning via digital platform, and therefore, digital means become a kind of a communication barrier for them, instead of being a unifying bond. The research objective is to summarize the experience of psychological and pedagogical interaction with the participants of the professional development program based on a digital educational platform in order to identify psychological and pedagogical defi ciencies of working teachers, who are enrolled in the professional development program, and the challenges faced by the experts of the training program. The study hypothesizes that the teacher-training professional development program, organized on the basis of a digital educational platform, will allow us to identify specifi c challenges to the expert community caused by the practice of exclusively distant interaction, on the one hand, and on the other hand, it will help to identify professional defi ciencies of working teachers and to overcome them. Participants: 53 teachers working in diff erent regions of the Russian Federation aged from 21 to 70 years old with work experience from 1 to 40 years. Methods (tools): the questionnaire for fi xing the psychological and pedagogical problems of the interviewees and the signifi cance of the professional activity (by I. V. Egorov, D. V. Naumova, T. V. Sklyarova, L. B. Schneider), the expert method (included observation and expert assessments) to determine the manifestation of professional competencies of teachers. Results. The research results helped to fi nd out that under the conditions of online learning, teachers demonstrate commitment to the position of a passive participant/listener, rather than an active co-author of the process. It is shown that adult education (of teachers, in particular) becomes a challenge to the expert community: the established mental patterns, individual and habitual models of obtaining knowledge determine the internal resistance and distrust to digital learning tools. It is revealed that the key shortage of the students is insuffi cient digital communication. Conclusions: to overcome teacher defi ciencies the authors propose the construction of an individual educational route for professional development and the use of gamifi cation techniques in digital learning. Practical signifi cance: the results obtained will allow to adjust the professional development programs that are conducted via the digital platfor
