Published: August 2023

Introduction. The article presents the overview of the Livvic dialectal audio materials stored in the Phonogram Archive of the Institute of Linguistics, Literature and History of the Karelian Research Centre of the Russian Academy of Science (Petrozavodsk).
Materials and Methods. The article is based on the digital information resources, folklore-ethnographic and linguistic data obtained in the ILLH KarRC RAS archives. The research was carried out using descriptive, comparative, historical and chronolohical methods.
Results and Discussion. The Institute’s Phonogram Archive stores field materials which have been collected by the Institute’s specialists since the 1930s. These are speech samples, folklore works, as well as information about the culture and life of the peoples living in the Republic of Karelia, and neighboring regions. The article considers collections of audio materials in the Livvik dialect of the Karelian language, which were collected on the territory of South Karelia in the Olonetsian, Pryazha’s, Suoyarvi’s, Pitkyaranta’s districts. They include not only speech samples, but also some data on ethnography, toponymy, folklore, etc. Part of the material from the Livvic collection (dialect and folklore-ethnographic materials) is presented in the article as the tables that help navigate it. It can be useful for a wide range of specialists: ethnographers, linguists, folklorists, historians.
Conclusion. The collections of Livvic dialect and folklore-ethnographic materials of the Phonogram Archive of the ILLH of the Karelian Research Centre of the Russian Academy of Sciences include valuable linguistic, folklore and ethnographic material. The authors have presented a small part of the unique material stored in the archive. Digitization of archival and field audio samples of Karelian speech in the format of a speech corpus can further simplify the processing and storage of materials, can make it possible to introduce into academic and research environment and make available the unique audio materials which reflect the state of Karelian and Vepsian dialects since the middle of the last century.

New aspects of weaving K-frames: the excess and duality
Authors: Agheshteh Moghaddam Elahe , Arefijamaal Ali Akbar
Published: August 2023

Weaving frames in separable Hilbert spaces have been recently introduced by Bemrose et al. to deal with some problems in distributed signal processing and wireless sensor networks. Likewise weaving K -frames have been proved to be useful during signal reconstructions from the range of a bounded linear operator K. In this paper, we study the notion of weaving and its connection to the duality of K-frames and construct several pairs of woven K-frames. Also, we find a unique biorthogonal sequence for every K-Riesz basis and obtain a $K^*$-frame which is woven by its canonical dual. Moreover, we describe the excess for K-frames and prove that any two woven K-frames in a separable Hilbert space have the same excess. Finally, we introduce the necessary and sufficient condition under which a K-frame and its image under an invertible operator have the same excess.

On sum annihilator ideals in Ore extensions
Authors: Paykanian Mahsa , Hashemi Ebrahim , Alhevaz Abdollah
Published: August 2023

A ring $R$ is called a left Ikeda-Nakayama ring (left IN-ring) if the right annihilator of the intersection of any two left ideals is the sum of the two right annihilators. As a generalization of left IN-rings, a ring $R$ is called a right SA-ring if the sum of right annihilators of two ideals is a right annihilator of an ideal of $R$. It would be interesting to find conditions under which an Ore extension $R[x; \alpha, \delta]$ is IN and SA. In this paper, we will present some necessary and sufficient conditions for the Ore extension $R[x;\alpha, \delta]$ to be left IN or right SA. In addition, for an $(\alpha,\delta)$-compatible ring $R$, it is shown that: (i) If $S = R[x;\alpha,\delta]$ is a left IN-ring with ${\rm{Idm}}(R) ={\rm{Idm}}(R[x;\alpha, \delta])$, then $R$ is left McCoy. (ii) Every reduced left IN-ring with finitely many minimal prime ideals is a semiprime left Goldie ring. (iii) If $R$ is a commutative principal ideal ring, then $R$ and $R[x]$ are IN. (iv) If $R$ is a reduced ring and $n$ is a positive integer, then $R$ is right SA if and only if $R[x]/(x^{n+1})$ is right SA.
Piecewise polynomial numerical method for Volterra integral equations of the fourth-kind with constant delay
Authors: PİSHBİN Saeed , DARANİA Parviz
Published: August 2023

This work studies the fourth-kind integral equation as a mixed system of first and second-kind Volterra integral equations (VIEs) with constant delay. Regularity, smoothing properties and uniqueness of the solution of this mixed system are obtained by using theorems which give the relevant conditions related to first and second-kind VIEs with delays. A numerical collocation algorithm making use of piecewise polynomials is designed and the global convergence of the proposed numerical method is established. Some typical numerical experiments are also performed which confirm our theoretical result.

Authors: AMİATAEİ Azim , DERAKHSHAN Mohammadhossein
Published: August 2023

In the present study, a mathematical model of non-steady partial differential equation from the process of oxygen mass transport in the human pulmonary circulation is proposed. Mathematical modeling of this kind of problems lead to a non-steady partial differential equation and for its numerical simulation, we have used finite differences. The aim of the process is the exact numerical analysis of the study, wherein consistency, stability and convergence is proposed. The necessity of doing the process is that, we would like to increase the order of numerical solution to a higher order scheme. An increment in the order of numerical solution makes the numerical simulation more accurate, also makes the numerical simulation being more complicated. In addition, the process of numerical analysis of the study in this order of solution needs more research work.
Malcev Yang-Baxter equation, weighted $\mathcal{O}$-operators on Malcev algebras and post-Malcev algebras
Authors: HARRATHİ Fattoum , MABROUK Sami , NCİB Othmen , SILVESTROV Sergei
Published: August 2023

The purpose of this paper is to study the $\mathcal{O}$-operators on Malcev algebras and discuss the solutions of Malcev Yang-Baxter equation by $\mathcal{O}$-operators. Furthermore we introduce the notion of weighted $\mathcal{O}$-operators on Malcev algebras, which can be characterized by graphs of the semi-direct product Malcev algebra. Then we introduce a new algebraic structure called post-Malcev algebras. Therefore, post-Malcev algebras can be viewed as the underlying algebraic structures of weighted $\mathcal{O}$-operators on Malcev algebras. A post-Malcev algebra also gives rise to a new Malcev algebra. Post-Malcev algebras are analogues for Malcev algebras of post-Lie algebras and fit into a bigger framework with a close relationship with post-alternative algebras.
On a minimal set of generators for the algebra $H^*(BE_6; \mathbb F_2)$ as a module over the Steenrod algebra and applications
Authors: TİN Nguyen Khac
Published: August 2023

Let $\mathcal P_n \cong H^{*}\big(BE_n; \mathbb F_2 \big)$ be the graded polynomial algebra over the prime field of two elements $\mathbb F_2$, where $E_n$ is an elementary abelian 2-group of rank $n,$ and $BE_n$ is the classifying space of $E_n.$ We study the {\it hit problem}, set up by Frank Peterson, of finding a minimal set of generators for the polynomial algebra $\mathcal P_{n},$ viewed as a module over the mod-2 Steenrod algebra $\mathcal{A}$. This problem remains unsolvable for $n>4,$ even with the aid of computers in the case of $n=5.$ By considering $\mathbb F_2$ as a trivial $\mathcal A$-module, then the hit problem is equivalent to the problem of finding a basis of $\mathbb F_2$-graded vector space $\mathbb F_2 {\otimes}_{\mathcal{A}}\mathcal P_{n}.$ This paper aims to explicitly determine an admissible monomial basis of the $ \mathbb{F}_{2}$-vector space $\mathbb{F}_{2}{\otimes}_{\mathcal{A}}\mathcal P_{n}$ in the generic degree $n(2^{r}-1)+2\cdot 2^{r},$ where $r$ is an arbitrary non-negative integer, and in the case of $n=6.$ As an application of these results, we obtain the dimension results for the polynomial algebra $\mathcal P_n$ in degrees $(n-1)\cdot(2^{n+u-1}-1)+\ell\cdot2^{n+u},$ where $u$ is an arbitrary non-negative integer, $\ell =13,$ and $n=7.$ Moreover, for any integer $r>1,$ the behavior of the sixth Singer algebraic transfer in degree $6(2^{r}-1)+2\cdot2^r$ is also discussed at the end of this paper. Here, the Singer algebraic transfer is a homomorphism from the homology of the Steenrod algebra to the subspace of $\mathbb{F}_{2}{\otimes}_{\mathcal{A}}\mathcal P_{n}$ consisting of all the $GL_n(\mathbb F_2)$-invariant classes. It is a useful tool in describing the homology groups of the Steenrod algebra, $\text{Tor}^{\mathcal A}_{n, n+*}(\mathbb F_2,\mathbb F_2).$
Inequalities for the $A$-joint numerical radius of two operators and their applications
Authors: FEKİ Kais
Published: August 2023

Let $\big(\mathcal{H}, \langle \cdot, \cdot\rangle \big)$ be a complex Hilbert space and $A$ be a positive (semidefinite) bounded linear operator on $\mathcal{H}$. The semi-inner product induced by $A$ is given by ${\langle x, y\rangle}_A := \langle Ax, y\rangle$, $x, y\in\mathcal{H}$ and defines a seminorm ${\|\cdot\|}_A$ on $\mathcal{H}$. This makes $\mathcal{H}$ into a semi-Hilbert space. The $A$-joint numerical radius of two $A$-bounded operators $T$ and $S$ is given by
\begin{align*}
\omega_{A,\text{e}}(T,S) = \sup_{\|x\|_A= 1}\sqrt{\big|{\langle Tx, x\rangle}_A\big|^2+\big|{\langle Sx, x\rangle}_A\big|^2}.
\end{align*}
In this paper, we aim to prove several bounds involving $\omega_{A,\text{e}}(T,S)$. This allows us to establish some inequalities for the $A$-numerical radius of $A$-bounded operators. In particular, we extend the well-known inequalities due to Kittaneh [Numerical radius inequalities for Hilbert space operators, Studia Math. 168 (1), 73-80, 2005]. Moreover, several bounds related to the $A$-Davis-Wielandt radius of semi-Hilbert space operators are also provided.

A criterion for nonzero multiplier for Orlicz spaces of an affine group $\mathbb{R}_{+}\times \mathbb{R}$
Authors: ÜSTER Rüya
Published: August 2023

Let $\mathbb{A}=\mathbb{R}_{+}\times \mathbb{R}$ be an affine group with right Haar measure $d\mu$ and $\Phi_i$, $i=1,2$, be Young functions. We show that there exists an isometric isomorphism between the multiplier of the pair $(L^{\Phi_1}(\mathbb{A}),L^{\Phi_2}(\mathbb{A}))$ and $(L^{\Psi_2}(\mathbb{A}),L^{\Psi_1}(\mathbb{A}))$ where $\Psi_i$ are complementary pairs of $\Phi_i$, $i=1,2$, respectively. Moreover we show that under some conditions there is no nonzero multiplier for the pair $(L^{\Phi_1}(\mathbb{A}),L^{\Phi_2}(\mathbb{A}))$, i.e., for an affine group $\mathbb{A}$ only the spaces $M(L^{\Phi_1}(\mathbb{A}),L^{\Phi_2}(\mathbb{A}))$, with a concrete condition, are of any interest.

Published: August 2023

In this article, we study the piezoelectric beams with thermal and magnetic effects in the presence of a nonlinear damping term acting on the mechanical equation. First, we prove that the system is well-posed in the sense of semigroup theory. And by constructing a suitable Liapunov functional, we show a general decay result of the solution for the system from which the polynomial and exponential decay are only special cases. Furthermore, our result does not depend on any relationship between system parameters.
On the computation of some code sets of the added Sierpinski triangle
Authors: ŞEN Aslıhan İklim , SALTAN Mustafa
Published: August 2023

In recent years, the intrinsic metrics have been formulated on the classical fractals. In particular, Sierpinski-like triangles such as equilateral, isosceles, scalene, added and mod$-3$ Sierpinski triangle have been considered in many different studies. The intrinsic metrics can be defined in different ways. One of the methods applied to obtain the intrinsic metric formulas is to use the code representations of the points on these self-similar sets. To define the intrinsic metrics via the code representations of the points on fractals makes also possible to investigate different geometrical, topological properties and geodesics of these sets. In this paper, we investigate some circles and closed sets of the added Sierpinski triangle and express them as the code sets by using its intrinsic metric.

Published: August 2023

Gel'fand Dorfman superbialgebra, which is both a Lie superalgebra and a (left) Novikov superalgebra with some compatibility condition, appears in the study of Hamiltonian pairs in completely integrable systems and a class of special Lie conformal superalgebras called quadratic Lie conformal superalgebras. In the present paper, we generalize this algebraic structure to the Hom-conformal case. We introduce first, Hom-Novikov conformal superalgebras and exihibit several properties. Then we introduce Hom-Gel'fand Dorfman superbialgebra and provide some construction results.
Nonconvex integro-differential sweeping processes involving maximal monotone operators
Authors: MANSOUR Mouchira , KECİS Ilyas , HADDAD Tahar
Published: August 2023

This paper is devoted to the study of a perturbed differential inclusion governed by a nonconvex sweeping process in a Hilbert space. The sweeping process is perturbed by a sum of an integral forcing term which the integrand depends on two time-variables and a maximal monotone operator. By using a semi-regularization method combined with a Gronwall-like inequality we prove solvability of the initial value problem.

Authors: DAVVAZ Bijan , ULUCAK Gülşen , TEKİR Ünsal
Published: August 2023

In this paper, we introduce new expansion classes, namely weakly $ (k,n) $-absorbing hyperideals and weakly $ (k,n) $-absorbing primary hyperideals of a Krasner $ (m,n) $-hyperring, including $ (k,n) $-absorbing hyperideal and $ (k,n) $-absorbing primary hyperideal. In summary, we give generalizations of $ (k,n) $-absorbing hyperideal and $ (k,n) $-absorbing primary hyperideal. Also, we examine the relationships between classical hyperideals and the new hyperideals and explore some ways to connect them. Additionally, some main results and examples are given to explain the structures of these concepts. Finally, we study a version of Nakayama's lemma on a commutative Krasner $ (m,n) $-hyperring.

Authors: GAO Yuan , PANG Bin
Published: August 2023

$\top$-convergence structures serve as an important tool to describe fuzzy topology. This paper aims to give further investigations on $\top$-convergence structures. Firstly, several types of $\top$-convergence structures are introduced, including Kent $\top$-convergence structures, $\top$-limit structures and principal $\top$-convergence structures, and their mutual categorical relationships as well as their own categorical properties are studied. Secondly, by changing of the underlying lattice, the ``change of base" approach is applied to $\top$-convergence structures and the relationships between $\top$-convergence structures with respect to different underlying lattices are demonstrated.
Graphs of schemes associated to group actions
Authors: KİŞİSEL Ali Özgür , ÖZKAN Engin
Published: August 2023

Let $X$ be a proper algebraic scheme over an algebraically closed field. We assume that a torus $T$ acts on $X$ such that the action has isolated fixed points. The $T$-graph of $X$ can be defined using the fixed points and the one-dimensional orbits of the $T$-action. If the upper Borel subgroup of the general linear group with maximal torus $T$ acts on $X$, then we can define a second graph associated to $X$, called the $A$-graph of $X$. We prove that the $A$-graph of $X$ is connected if and only if $X$ is connected. We use this result to give proof of Hartshorne's theorem on the connectedness of the Hilbert scheme in the case of $d$ points in $\mathbb{P}^{n}$.

Statistically order compact operators on Riesz spaces
Authors: Aydın Abdullah
Published: August 2023

This research paper introduces and establishes the concept of compact operators in the context of Riesz spaces, specifically considering statistical order convergence. We define statistical order compact operators as operators that map statistical order bounded sequences to sequences with statistical order convergent subsequences. Additionally, we define statistical $M$-weakly compact operators. By utilizing these non-topological concepts, we derive some new results pertaining to these operators.
Regarding equitable colorability defect of hypergraphs
Authors: SHAEBANİ Saeed
Published: August 2023

After Lovász’s break-through in determining the chromatic number of Kneser graphs (1978), and after extending this result to the chromatic number of $r$-uniform Kneser hypergraphs by Alon, Frankl, and Lovász’s (1986), some important parameters such as colorability defect and equitable colorability defect were introduced in order to provide sharp lower bounds for the chromatic number of general $r$-uniform Kneser hypergraphs. As a generalization of many earlier results in this area, Azarpendar and Jafari (2023) introduced the $s$-th equitable $r$-colorability defect ${\rm ecd}^r (\mathcal{F} , s)$; a parameter which provides a lower bound for the chromatic number of generalized Kneser hypergraphs ${\rm KG} ^r (\mathcal{F} , s)$. They proved the following nice inequality
$$\chi \left( {\rm KG} ^r (\mathcal{F} , s) \right) \geq \left\lceil \frac{ {\rm ecd}^r \left( \mathcal{F} , \left\lfloor \frac{s}{2} \right\rfloor \right) }{r-1} \right\rceil ,$$
and noted that it is plausible that the above inequality remains true if one replaces $\left\lfloor \frac{s}{2} \right\rfloor$ with $s$.

In this paper, considering the relation
${\rm ecd}^r \left( \mathcal{F} , x \right) \geq {\rm cd}^r \left( \mathcal{F} , x \right)$ which always holds, we show that even in the weaker inequality
$$\chi \left( {\rm KG} ^r (\mathcal{F} , s) \right) \geq \left\lceil \frac{ {\rm cd}^r \left( \mathcal{F} , \left\lfloor \frac{s}{2} \right\rfloor \right) }{r-1} \right\rceil ,$$
no number $x$ greater than $\left\lfloor \frac{s}{2} \right\rfloor$ could be replaced by $\left\lfloor \frac{s}{2} \right\rfloor$.
The Legal Regulation Development of Key Technologies of Industry 4.0: Digital Tokens as Special Investment Instruments
Authors:   Volgograd State University, Matytsin Denis
Published: August 2023

Introduction. In the modern information space, digital assets are becoming increasingly popular. For example, tokenized stocks, bonds, and other financial instruments, which are represented by special digital algorithms, are getting used in the investment turnover; they are so called because of the word “token.” These digital algorithmscodes exist and are only accessible within blockchain technology. The specified digital code is functionally a legal substitute for the right to participate in the business of a joint-stock company, or, as a variant of a bond, a legal substitute for a monetary claim of a certain person (the lender) against another person (the borrower). Falsification of a digital token (substituting by some other software algorithm-code) is impossible. The judicial practice that developed before the adoption of the legislative act in 2020 and came into force in 2021 had a contradictory and fragmented character. In this connection, the author sets the goal of continuing to analyze the new federal legislation to improve the procedure for protecting investors’ rights, developing investment turnover, and enhancing the investment climate. Methods. The methodological framework for the study is the methods of scientific cognition, among which the main ones are systematicity, analysis, and comparative law. Results. The behaviors for legal protection are considered, which must necessarily be realized and evaluated by investors when investing in tokens of a particular project. The issue of procedures for the protection of violated rights is raised. The author makes distinctions between token protection in the legal system, legislation, and law enforcement practice. Conclusions. Based on the analysis of the new federal legislation, further doctrinal elaboration is required to substantiate effective procedures for protecting the rights of investors that may be violated in the process of the turnover of digital investment instruments in the modern Internet space.

Authors:   Office of the Commissioner for Human Rights in the Irkutsk Region, Ustinov Andrey , Iakimova Ekaterina ,   Baikal State University
Published: August 2023

The right to a stable national currency is considered in the presented study as one of the types of economic rights of citizens, ensuring the realization of personal, political, social and other economic rights, since the stability of the national currency allows citizens and the state to plan the costs of implementing rights and guarantee the fulfillment of obligations assumed by the state. During the constitutional reform of 2020, the right in question received additional constitutional regulation, which requires scientific understanding. The purpose of the work is to determine the degree of influence of the constitutional reform of 2020 on the level of constitutional guarantee of the right to a stable national currency in the Russian Federation. Methods. As part of the study, mainly special methods of cognition of socio-legal phenomena (the formal legal method, circular causality method) were used which allowed assessing the impact of the correction of the language of the Constitution of the Russian Federation by provisions establishing additional guarantees for the implementation of the constitutional right to a stable national currency, and to identify the potential for improving the constitutional and current legislation to ensure the implementation of the designated right. Results. The significance of the constitutional reform of 2020 on increasing the level of guarantee of the constitutional right to a stable national currency has been revealed. Conclusions. Despite the adjustment of the provisions of the Constitution of Russia, there is still a potential for improving the constitutional and current legislation, whose implementation would ensure the guarantee of the right to a stable national currency of the Russian Federation.
Traditional Family Values in the Social and Legal Thought of Russia in the 19th – Early 20th Centuries
Authors:   Volgograd Institute of Management, Branch of the Russian Presidential Academy of National Economy and Public Administration, Mun Viktoriya
Published: August 2023

Introduction. An important guideline in the legal evolution of Russia is the preservation of traditional family values. The idea of preserving traditional family values is reflected in the Basic Law and official policy papers and is consistently implemented in state programs and national and federal projects. The understanding and legal formalization of the concept of traditional family values are conditioned by the need to preserve the Russian identity and moral guidelines in society. The analysis of historical experience will contribute to the development of an adequate model of Russia’s cultural identity. The research on the concept of traditional family values in the works of outstanding pre-revolutionary ethnographers, anthropologists, historians, philosophers, lawyers, and public figures has formed the purpose of the study. Methods. The methods of historicism, systematicity, analysis and comparative law. Results. The study analyzes the works of Russian pre-revolutionary ethnographers, anthropologists, historians, philosophers, lawyers, and public figures according to the concept and content of traditional family values in Russia in the 19th – early 20th centuries; a theoretical and legal analysis of the categories “tradition”, “value”, and “family” is also made; and the role of traditions in law is investigated. Conclusions. The preservation of traditional family values, increasing the role of the family in society and increasing the authority of parenthood in the family and society are currently relevant priorities for state family policies. The pre-revolutionary Russian legislation considered marriage a religious act; hence, the legal regulation of family relations at the conclusion and dissolution of marriage was based on the religion of the spouses and the recognition of the exclusively ecclesiastical form of marriage. According to the Russian social and legal thought of the 19th – early 20th centuries, traditional family values were based on such aspects as natural (sexual), including the physiological mutual desire of spouses; spiritual, consisting in mutual love and affection of spouses; reproductive, associated with childbirth; and the desire to continue the family and transfer knowledge and skills from generation to generation.

Introduction. Currently, human rights to medical care and health protection in our country are regulated by the Constitution of the Russian Federation, federal laws and by-laws. And, accordingly, to realize these rights, the state needs to form, allocate and effectively spend a sufficient amount of financial resources. The purpose of the study is to analyze the procedure and sources of healthcare financing in the constituent entities of the Russian Federation. Methods. The analysis of modern scientific literature, as well as the regulatory framework on the procedure and sources of healthcare financing in the Russian Federation is carried out. For this purpose, the methods of bibliographic, informational and semantic search of sources in various databases are used. Results. The sources of financing the healthcare system in the Russian Federation are employers’ insurance premiums for Compulsory Health Insurance (CHI) of the working population, insurance premiums from the budgets of the constituent entities of the Russian Federation for CHI of the non-working population, as well as expenditures of regional budgets and inter-budgetary transfers. The CHI system is currently the main source of funding for the state healthcare system in the Russian Federation. Single-channel financing made it possible to increase the efficiency of the healthcare system and played a positive role during the pandemic, which allowed the system to compensate for epidemiological risks quite quickly, but currently there are problems that require the reform of the healthcare system. The disadvantages of the CHI system are the complexity of the medical care financing chain, as well as the problems of distributing the capacity of medical care between medical organizations within the framework of the territorial CHI program. From the standpoint of the objective situation of insufficient financing of healthcare in the Russian Federation, it is advisable not so much to increase financial resources as to increase the efficiency of the use of allocated funds, which requires the legislative consolidation of responsibility for their irrational use, as well as strengthening the state control of resources allocated to healthcare. Conclusions. The activities of the Compulsory Health Insurance system require strengthening public control measures.

Purpose. Modern methodologies for maintaining technical facilities are focused on simultaneously ensuring a given level of equipment reliability and minimizing system maintenance costs. The development of maintenance systems is usually based on the use of equipment reliability data, analysis of diagnostic results and forecasting of the residual life of locomotive equipment. In addition, the development of maintenance systems takes into account the costs of maintenance and repair of components. The main goal of the study is to increase the efficiency of the locomotive fleet by reducing the cost of maintaining locomotives, taking into account the technical condition of its components. Methodology. To achieve this goal, we propose a methodology for determining the rational periods for diagnosing locomotive components based on minimizing the cost of diagnostics and performing maintenance and repair of equipment. To determine the frequency of control, we used data on the reliability of components and parts obtained from the processing of statistical information on the operation of locomotives in operation, as well as data on the costs of restoring components in the event of failures. Findings. A method for determining the rational periods for diagnosing locomotive components based on minimizing the cost of diagnosing and restoring them in case of failure is proposed. Based on the analysis of the reliability of hydraulic transmissions of locomotives in their operation, the reliability indicators of hydraulic transmission units and parts are determined in the form of dependencies of the average number of hydraulic transmission failures on the operating time of the locomotive. A techno-economic map of hydraulic transmission repair and a techno-economic map of its diagnostics have been developed. The results of determining the frequency of diagnostics of the hydraulic transmission UGP750–1200PR of diesel locomotives TGM4 and TGM6 are presented. Originality. The methodology for determining the frequency of monitoring the technical condition of locomotive components has been further developed by taking into account the impact of the system of preventive, scheduled maintenance and diagnostics on the reliability of the locomotive. Practical value. The use of the proposed methodology for the formation of a system for repairing and diagnosing locomotives and their components will allow the formation of a system for maintaining locomotives taking into account their actual condition.

Abstract The pandemic of COVID-19 demanded unprecedented efforts from psychologists to adapt to technology-mediated care. This study aimed to analyze the scientific production concerning the perception of Brazilian psychologists on online psychotherapy during the pandemic through a scoping review. We consulted four databases, while the reviewed corpus comprehended 29 studies. Psychologists identified both benefits and barriers in the transition to online psychotherapy practice, but the perception that the sparing use of this resource is valid and beneficial predominated. There is a strong perception that information and communication technologies will definitely integrate the repertoire of resources used by psychotherapists, as another relevant alternative, posing the need for further studies.
CONTRIBUIÇÕES DAS NEUROCIÊNCIAS PARA A APRENDIZAGEM ALÉM DA SALA DE AULA
Authors: Rodrigues Felipe Viegas
Published: August 2023

A despeito da educação formal existir há milênios e a psicologia contribuir com a compreensão da aprendizagem há mais de cem anos, técnicas eficazes de aprendizagem continuam ausentes do repertório de estratégias dos estudantes. Este trabalho teórico foca em insights da neurociência para a aprendizagem de estudantes e examina a efetividade das estratégias de estudo comumente empregadas. Um achado fundamental é que as memórias tendem ao esquecimento a menos que as emoções sejam engajadas no momento da aquisição da informação ou que ocorra uma repetição explícita do processo de aprendizagem. Além disso, prestar atenção integral ao conteúdo desejado é fundamental para otimizar a formação de traços de memória efetivos. Dessa forma, não é surpreendente que técnicas com baixa relevância para os mecanismos de atenção ou com interação limitada com as informações – como grifar textos, fazer uma leitura simples, usar palavras-chave ou imagens mentais e até mesmo fazer resumos – tenham eficácia baixa. Por outro lado, envolver-se em exercícios de resolução de problemas e estabelecer uma rotina de estudos que distribui e promove acessos espaçados à informação, engaja aspectos fundamentais dos circuitos de atenção e facilita a formação de traços de memória robustos, o que maximiza a probabilidade de aprendizagem efetiva. A aplicação correta de estratégias que se fundamentam nos mecanismos pelos quais o cérebro armazena informações é a maneira mais efetiva de se produzir aprendizado duradouro.
DYNAMIC ANALYSIS OF THE VISCOELASTIC MICROTWEEZER UNDER ELECTROSTATIC FORCES AND THERMAL FIELDS
Authors: Nie Ju
Published: August 2023

This is the first study to examine the nonlinear dynamic behavior of a microtweezer under electrostatic forces by
taking into account viscoelastic effects and linear and nonlinear thermal stresses. The van der Waals (vdW) forces
and Casimir intermolecular forces have been included in order to consider more realistic assumptions. Hamilton's
principle is applied to derive the nonlinear equations governing the system. A nonlinear partial differential equation has been converted into an ordinary nonlinear differential equation using the Galerkin method. The equations are numerically solved and the results are analyzed at different values of the effective parameters, such as the coefficients of the Casimir force and the vdW forces. Results indicate that the increase in the small size parameter and Casimir and vdW forces results in a decrease in the equivalent stiffness and, therefore, a decrease in the pole's voltage. In addition, the viscoelastic behavior causes a significant change in the stability behavior of the microbeams, and with an increase in damping, the resonance frequency increases by about 33%. Therefore, it is essential to take into account the effect of viscous damping when designing a microtweezer.
ONSET OF DOUBLE-DIFFUSIVE CONVECTION WITH A KELVIN–VOIGT FLUID OF VARIABLE ORDER
Authors: Dhumd D. Z. , Haddad Shatha A.
Published: August 2023

The onset of double-diffusive convection in a horizontal layer, which is heated and salted from below, of Kelvin-Voigt fluid of order two is studied. The linear instability theory is applied to investigate the influence of salt concentration and viscoelastic parameters on the stability of the system. The critical values of Rayleigh numbers are calculated by utilizing the golden section search in the Matlab platform. The results confirm that for different values of the Kelvin-Voigt parameter and the viscoelastic parameters, the onset of convection is delayed, while the salt concentration advances the onset of convection.

Authors: Kim Il Sun , Choi So Yeong , Yang Eun Ik
Published: August 2023

The fundamental properties and durability of mortar mixed with phytoncide, zeolite or copper powder were evaluated. For different phytoncide substitution ratios (SRs), there was no significant difference in the flow, compressive strength and flexural strength of the mortar. With an increase in the SR of zeolite, the workability decreased, while the compressive strength, flexural strength and chloride penetration resistance increased. The compressive and flexural strengths of the mortars mixed with copper powder were higher than those of the reference mix. With an increase in the SR of copper powder, the flow slightly increased and the chloride penetration resistance decreased.
Prediction of fire spalling behaviour of fibre-reinforced concrete
Authors: Jiang Jin , Wu Ming , Ye Mao
Published: August 2023

Fire spalling prediction of fibre-reinforced concrete containing polypropylene (PP) or steel fibre at elevated temperatures is challenging. It is difficult to use conventional methods, such as finite-element modelling and discrete-element modelling, to solve the problem, because of the complicate coupling mechanism of PP and steel fibres in concrete. To this end, two artificial neural network (ANN) models, one (ANN1) based on a concrete mix study and the other (ANN2) based on a compressive strength study, were introduced to assess the resistance of concrete to explosive spalling. Test data (321 and 318 items, respectively) gathered from the literature were utilised to train the proposed models. Twenty-four concrete mixes (96 groups), that is, seven plain concrete mixes, four high performance concrete mixes reinforced with PP fibre, three ultra-high-performance concrete (UHPC) mixes with reinforced PP fibre and ten UHPC mixes reinforced with PP and steel hybrid fibres were designed and tested to validate the accuracy of the models. The study demonstrates that ANN1 and ANN2 can achieve a predictive accuracy of 89.6% and 84.4% for the explosive spalling, respectively, indicating the feasibility of the proposed models for predicting explosive spalling threat of the hybrid fibre-reinforced concrete.
Early Medieval Language and Literature as Heritage: a Sutton Hoo Case Study
Authors: Allfrey Fran
Published: August 2023

This article is both a reflection on the cultural, social, and political stakes of how early medieval literature and language functions as heritage in England, and on my practices as a museum educator. Language and literature in heritage contexts may enable rich emotional and intellectual engagement with early medieval stories, landscapes, and objects in ways which may unloose the early medieval from the grip of exclusionary narratives. I discuss how Old English language and literature may be understood within wider contexts of early medieval heritage, often called ‘Anglo-Saxon’ in English institutions, by sketching the overlapping public spaces of encounter with the past, and how we may read across them. With its longstanding links with Old English poetry across scholarship and public history, I suggest that Sutton Hoo provides an ideal case study for examining the enmeshment of early medieval literature, language, landscape, and archaeology as heritage categories. I discuss the planning and delivery of ‘Trade and Travel’, a temporary display and learning programme that I organised with the National Trust in 2017, and present findings from qualitative data I collected to suggest how people make sense of place, archaeology, and early medieval language and literature. Understanding language and literature as heritage, I show how visitors discover and create meaning through encounter and conversation. In heritage spaces, literature and language are sensory and emotional artefacts and experiences: observing visitor engagement reveals how both become integral to creative and identity-making work.
