Published: December 2022

Commercial streets are places that considered as heart of our cities that are mostly intertwined with people’s everyday routines facilitating many activities, movements, and social interactions. The previous studies have researched the streets’ characteristics and qualities to enhance and evaluate the image of the streets and places. But, a less focus has been given to the commercial streets in the Sri Lankan context. The aim of this study is to identify the attributes that influence people’s sense in the commercial streets. The study was conducted in two commercial streets of Jaffna city and emphasis was given to qualitative analysis. Nine attributes namely access, number of people, street vendors, and variety of shops, trees and vegetation, walkways, lighting at night, pedestrians, and wall arts are found as influencing attributes for people’s sense in the selected two cases. It concluded that the activity as the most influential aspect which needs to be considered in facilitating the sense of place in the commercial streets. This paper will contribute to planners, architects, and designers to create and arrange the commercial streets as a meaningful place for people.

BACKGROUND

Reports of cerebrovascular ischemia and stroke occurring as predominant neurological sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which causes coronavirus disease 2019 (COVID-19), are increasingly evident within the literature. While various pathophysiological mechanisms have been postulated, including hypercoagulability, endothelial invasion, and systemic inflammation, discrete mechanisms for viral neurotropism remain unclear and controversial.

OBSERVATIONS

The authors present a unique case study of a 64-year-old male with acute COVID-19 infection and acute worsening of previously stable cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a rare heritable arteriopathy due to mutation in the Notch3 gene, which is critical for vascular development and tone. Delayed cranial neuropathies, brainstem fluid-attenuated inversion recovery signal, and enhancement of olfactory and vagus nerves on magnetic resonance neurography in this patient further support viral neurotropism via cranial nerves in addition to cerebral vasculature.

LESSONS

To the authors’ knowledge, this is the first case in the literature that not only demonstrates the consequences of COVID-19 infection in a patient with altered cerebrovascular autoregulation such as CADASIL but also highlights the tropism of SARS-CoV-2 for (1) cranial nerves as a mode of entry to the central nervous system and (2) vessels as a cause of cerebrovascular ischemia.
THE INFLUENCE OF NASAL BREATHING DISORDERS ON THE ORAL FLUID PARAMETERS IN PRESCHOOL CHILDREN
Authors: Ulasevych L.P.
Published: December 2022

Dental caries is the most common dental disease in preschool children. Negative changes in the quantitative and qualitative parameters of oral fluid create optimal conditions for the development of cariogenic situation. One of the most important factors of oral cavity homeostasis changes in children of 3-6 years old is a persistent disorder in nasal breathing.

The aim of the research is to determine the rate of saliva secretion and mixed saliva viscosity for their possible implementation as the biomarkers of risk of tooth caries appearence and justification of therapeutic and preventive measures prescription for elimination of the cariogenic situation in preschool children with persistent nasal breathing disorders. The rate of salivation and the viscosity of oral fluid were determined according to the method of Redynova T. L., Pozdeev A. R. (1994).

The analysis of the obtained data on the rate of salivation of the examined children of the main and control groups revealed that the average value is within the normal range or at the lower margin of the parameter. A 1.5-fold decrease in the rate of salivation was found in children with persistent nasal breathing disorders compared to practically healthy children (р≤0.05). A more pronounced parameter decrease is observed in case of deciduous teeth presense. The average value of the viscosity of oral fluid is 2 times higher in children with persistent nasal breathing disorders than in the control group (р≤0.05). Higher viscosity of mixed saliva was found in children with caries than in children without it, but in the main group the numerical values were significantly higher (р≤0.05).

The obtained data confirms the possibility of implementation of the determination of saliva secretion and viscosity rate as biomarkers of the tooth caries development in preschool children and provide an opportunity to control the application of therapeutic and preventive measures, considering the presence of nasal breathing disorders.

Published: December 2022

This study aims to analyse the effect of Facebook as a social learning environment in relation to students’ self-regulation (SR), critical thinking (CT) and learning performance in an e-Commerce course. A total of 295 undergraduate students taking the course were selected using cluster random sampling to identify their SR and CT. 50 out of 295 students were then selected purposively and were involved in the intervention process of e-Commerce course learning using Facebook. The post-test result indicated that SR, CT and learning performance in e-Commerce learning had improved after they went through the intervention process. Meanwhile, a positive correlation could be seen between CT and learning performance only, when analysed using Pearson correlation. Furthermore, a cross-tabulation analysis revealed a positive relationship pattern between the students’ SR, CT and learning performance. Hence, this suggests that academic performance can be improved through SR and CT.

Technological, social, and environmental changes are occurring globally. The disruption of technology will impact all sectors of human life. Sociocultural changes occur in the demographics and socioeconomics of the world population. During this chaotic condition, the Indonesian nation, with a large population and natural resources, must inevitably adapt to the global environment. Statistics Center Agency and World Bank data show that Indonesian student enrollment rates are rising, but preschool and tertiary gaps remain. Despite rising student enrollment, Indonesian education remains in crisis. One of the backbones of the nation's civilization to face global competition is good and mature planning in the education sector that adapts to global demands. This paper reviews the future of Indonesian education based on the mapping between Ki Hadjar Dewantara’s education model, the Indonesian education roadmap 2020-2015, the disrupted education model in 2020, The WEF Education 4.0 Framework, and the Future of the classroom model. This paper results in a future Indonesian education model framework to realize Indonesia's education vision for 2035.

Introduction: Patients’ mothers who are admitted to the maternity ward, as well as the nurses who work in the maternity department, may have learning needs or nursing care priority needs. On the other hand, the majority of studies have concentrated their attention on the mother’s knowledge in a variety of domains, and the majority of the research has been carried out in hospitals. Aims: The purpose of this study was to evaluate the efficacy of foot reflexology in promoting lactation in postnatal women. The goals of this study are to determine whether or not foot reflexology stimulates lactation in the experimental group. Methods: At a particular hospital in Karad city, postnatal mothers participated in a descriptive research study that was carried out. The evaluation of sixty postnatal caesarean mothers was carried out with the use of the purposeful sampling technique. The LATCH scale was used to collect data from postnatal moms using a semi-structured questionnaire. The questionnaire was designed to gather background information. Result: The results of the study showed that postnatal women had their lactation levels tested and evaluated to determine how far along they had progressed. With a standard deviation of 0.75 and 0.50 respectively, the mean LATCH score of postnatal caesarean moms in the experimental group using the LATCH breastfeeding assessment scale was 3.53, and it climbed to 9.08 following Reflex zone Stimulation. Foot massage is helpful for post-natal mothers in improving their ability to breastfeed their children. According to the results of the study, the administration of reflex zone therapy is an effective method for initiating the release of breast milk and promoting breastfeeding. Conclusion: The findings demonstrated that stimulating the reflex zones was a very useful method for increasing the amount of breast milk produced by postnatal mothers. The findings demonstrated that reflex zone stimulation is an extremely efficient method for increasing the amount of milk produced by postnatal moms.

The Effect of Temperature on the Creep Ageing Characteristics of Al-Li Alloys
Authors: Feng Tong , Ma Bolin , Chen Fei , Zhan Lihua , Xu Yongqian , Yang Chunyu
Published: December 2022

Abstract: In this paper, the evolution of creep strain and mechanical properties of 2195 Al-Li alloy is investigated at different temperatures (160/170/180°C), with the aim of discovering the mechanism of temperature influence on creep properties and providing a reference for improving the creep properties of the target material by adjusting the temperature in the future. This study demonstrates that the creep curve is strongly influenced by temperature, with a plateau and a transition period occurring at low temperatures. As the temperature increases, the creep curve gradually reverts to the typical two-stage creep characteristics due to the interaction of dislocation density proliferation and dislocation reversion within the material at high temperatures. In addition, by means of tests such as TEM, it was confirmed that the decrease in mechanical properties of the material caused by increasing the creep temperature is mainly due to the coarsening of precipitates and the appearance of precipitation-free zones at grain boundaries.

Abstract. The Baikalsk Pulp and Paper Mill (BPPM) was functioning on the shore of Lake Baikal for almost 50 years. These years of operation inevitably imposed specific adverse effects on the lake ecosystem. Finally, the BPPM was closed in 2013 but with no measures to mothball the plant. During 2013 2016, we observed a few atypical phenomena through our complex investigations of the coastal zone area next to the BPPM. Water temperature measurements, hydrochemical analysis, and FTIR spectroscopy showed these phenomena as unusual for Lake Baikal s pristine coastal areas. (1) We noted an anomalously high temperature of the interstitial water of the beach next to the BPPM. The water from the hole on the beach reached a temperature of 25 C in June 2013. (2) The hydrochemical parameters of the water from the beach were analyzed, and the interstitial water there exhibited an appreciably lower concentration of oxygen and higher content of sulfur, sodium, and chlorine comparing the lake s water. (3) We discovered the specific black depositions to cover the stones of the target beach. The IR spectrum of those depositions was found to be identical to the BPPM sludge-lignin. All these observations and results of chemical analyses point out that the industrial site of the nonfunctioning plant is still a substantial source of pollution, which negatively influences the Southern Baikal coastal zone ecosystem.

Abstract. This work was aimed to a comparative analysis and reconstruction of the phylogenetic position of sunbleak Leucaspius delineatus (Heckel, 1843) from the Irkutsk Reservoir. Determination of a species specific fragment of the Cox1 gene allowed to reveal a unique common haplotype present in all specimens analyzed. Comparative analysis and phylogenetic reconstruction based on nucleotide sequences available in genetic databases showed that the studied species is represented by three phylogenetic lineages. Intraspecific differences of nucleotide sequences of fragments of the Cox1 gene amounted to 5.5%, and within phylogenetic lineages - < 3%. The studied fishes were related to the genetic lineage widely distributed in Europe and northwestern Russia. It is shown that all specimens with 100% genetic similarity belong to the same genotype, which is due to recent introduction of sunbleak into Pre-Baikal and to the founder effect .

Published: December 2022

The relevance of the study is conditioned by the need to create an effective model of the current institutional environment that can ensure the unity of economic processes in the management of rural territories in Ukraine based on the best foreign practice. The purpose is to summarise the experience of the EU countries on the functioning of institutional models for managing rural development for adaptation in Ukraine. The task is to formulate conceptual approaches to the formation of an institutional model for managing rural development in Ukraine, considering the fundamental principles of building a system for rural development management in the EU countries. General scientific methods were used as a tool for obtaining information for informed management decisions in the field of rural development management: analysis and synthesis; induction, deduction and analogy; abstraction; generalisation; idealisation, etc. The main trends and priorities of the agricultural policy implemented by the European Union are considered. Centralised and decentralised rural development management systems are described. Heterogeneous management models between centralisation and decentralisation are presented. The multi-level nature of the management concept as a key specific component is substantiated. The functioning of the system of distribution of tasks between the European Commission, the national state, and the regions is considered. Models of distribution of programming and management competencies in various management systems, and the forms of relations between different levels of government have been improved. The procedure for the functioning of the rural development programming system in Germany is presented. The classification of different countries based on the distribution of responsibility for managing programmes that were intended for rural development is considered. Vertical coordination and relations between the state and regions in countries with a decentralised form of governance are analysed. Methodological approaches to the development of an institutional model for managing rural development are proposed. The practical significance of the study lies in the development of recommendations that improve the efficiency and consistency of management decisions on the establishment of an institutional model for managing rural development in the Ukrainian economy.

Published: December 2022

In the context of market relations development and rapid changes in technological support and technologies, it is necessary for enterprises to use not only publicly available material and financial resources, but also to operate with non-material resources, namely intellectual property objects, to ensure competitive advantages. This is an effective approach to increase the profitability and competitiveness of the enterprise. Improving the methodology and organisation of evaluation of potato varieties for various economic purposes as intellectual property as part of intangible assets is relevant and allows determining the market value of the variety, eliminates errors in calculating the price, and contributes to profit. The purpose of the study is to develop methodological recommendations for assessing the value of potato varieties as an object of intellectual property. The study was based on theoretical elaborations of Ukrainian and foreign scientists. The materials of statistical reporting of agricultural enterprises engaged in the production of seed potatoes, developments of research institutions, data of the Ministry of Agrarian Policy and Food of Ukraine, the State Statistics Service of Ukraine were used for the research. The economic evaluation of breeding stages of creation of potato varieties for different economic purposes was carried out. Methodological approaches to assessing the value of potatoes as an object of intellectual property, and economic mechanisms for ensuring the acquisition of intellectual property rights and use of newly created potato varieties, have been developed. The stages of the breeding process of creating a variety from an economic point of view are studied. The most expenditure stages of breeding are determined. The importance of the direction of use of the variety and the impact on the cost of its creation are analysed. Methodological recommendations for estimating the cost of potato seeds have been elaborated, allowing to establish the payback period of the variety.

Published: December 2022

Two kinds of aluminum alloy, 1561 and 1565 alloys, were tested in parallel within impact velocity range of 250–750 m/s in two schemes of shock loading: (i) under uniaxial strain conditions and (ii) in high velocity penetration. Combination of load regimes allows a formation of multiscale structure to be retraced. In both schemes of dynamic loading, the transition into structure-unstable state and change of scale level of dynamic deformation was found to occur under identical impact velocities. Formation of mesoscale-1 (1–10 µm) for both alloys is found to be identical – the mesoscale-1 structures are nucleated due to particle velocity fluctuations resulting from interaction of shock front with the structural hetero-geneities. The intensity of the velocity fluctuations is registered in real time in tests under uniaxial strain condition by using the interferometric technique. For the mesoscale-2 (50–150 µm), the formation of dynamic structures is studied by using microstructural data of post-shocked specimens. In 1561 alloy, the structural elements in the form of cell-structures of 50–150 µm are the result of collectivization of mesoscale-1 structures whereas in 1565 alloy the mesoscale-2 structures are the periodical fault-cellson the boundary of penetration cavern. The strength behavior of both kinds of aluminum alloys in different schemes of loading turns out to be opposite – where the resistance to penetration increases, the spall strength decreases.
A 3D HIGHER-ORDER GRADIENT MODEL FOR A HALF-SPACE GEOMEDIUM
Authors: Pavlov I.S. , Muravieva A.V.
Published: December 2022

In this paper, a structural model of a geomedium (a soil) is proposed in the form of a simple cubic lattice of spherical particles (blocks) possessing three translational and three rotational degrees of freedom. The force and couple interactions between the particles are modeled by elastic springs of five types. A long-wavelength continuum mathematical model of the soil has been elaborated by the method of structural modeling. An analytical relationship between its macroconstants and microstructure parameters has been found. It is shown that the obtained model differs from the model of the reduced Cosserat medium, which is often employed to describe granular media. In the low-frequency approximation, it can be reduced to the equations of the higher-order gradient theory of elasticity, which are similar to the Cosserat continuum equations with constrained rotation of particles. These equations contain both terms with mixed derivatives with respect to time and coordinate that take into account the inertia of particles rotation in the medium and lead to the wave dispersion, and terms proportional to the spatial derivatives of the fourth order, which describe the contribution of stresses caused by bending of the medium to the potential energy.
In the framework of the higher-order gradient model, expressions for the classical and couple stresses in the considered geomedium are found. Boundary conditions are set that consist in the absence of normal and shear stresses on the upper platform of a half-space medium. A condition for the microstructure parameters has been revealed, under which the couple stresses can be neglected.
The proposed here higher-order gradient model with given boundary conditions can be used to investigate the propagation and interaction of elastic waves in a semi-infinite geomedium, which are generated by the high-speed movement of trains, as well as to identify and study potentially dangerous effects caused by such movement.

Authors: Bondar V.S. , Abashev D.R. , Fomin D.Yu.
Published: December 2022

Variants of theories of plastic flow under combined hardening, widely used in practical calculations of structures, are considered. A comparative analysis of the variants of theories under complex loading along plane and spatial deformation trajectories is carried out, covering a wide range of trajectories from multi-link polylines to curved trajectories of variable curvature and torsion. Trajectories from medium to large curvature and torsion are considered. The analysis of the research results is carried out in the vector space of A.A. Ilyushin. The plane trajectories of deformations in the form of a square and a curved trajectory of variable curvature in the form of an astroid are considered, as well as the spatial trajectory of deformations of variable curvature and torsion in the form of a helix. The results of calculations are compared with the results of experimental studies on stress response trajectories, scalar and vector properties. Variants of the theories are considered: the isotropic hardening model; the Ishlinski–Prager–Kadashevich–Novozhilov model (linear kinematic hardening + isotropic hardening); a model similar to the Ono–Wang model; the Armstrong-Frederick-Kadashevich model; the Shabosh model with three Armstrong–Frederick–Kadashevich evolutionary equations; the Temis model based on the invariant theory of plasticity; the Cooper model with a three-membered structure the evolutionary equation for kinematic hardening. The material parameters (functions), the closing versions of the theories of plasticity are given. Satisfactory compliance with the experiment for all deformation trajectories is achieved by calculations based on the Shabosh and the Bondar models – the difference between the results of calculations and experiments does not exceed 30% with the best correspondence to the experiment of the Bondar model. It should be noted that the Bondar plasticity model is closed by three parameters of anisotropic hardening and one function of isotropic hardening, and the Shabosh model is closed by six parameters and one function.

Published: December 2022

A single interaction of a wave propagating in an inhomogeneous plate in the form of an infinite strip with a one-dimensional distributed mechanical object is considered. A distributed object is understood as a rod lying on a viscoelastic foundation that performs bending and torsional vibrations. It is considered that the plate has different parameters to the left and to the right of the rod. Physically and mathematically correct conditions at the interface between a plate and a rod are obtained as a consequence of the formulation of contact problems of the dynamics of two-dimensional elastic systems with one-dimensional loads, based on the variational principle of Hamilton – Ostrogradsky. The frequencies and wave numbers of the secondary (reflected and transmitted) waves, as well as the critical frequency, below which the wave does not propagate in the plate, are determined. Based on the solution of the kinematics problem from a system of linear algebraic equations obtained from the boundary conditions, the coefficients of reflection and transmission of bending waves are found. These coefficients resonantly depend on the frequency of the incident wave. Calculated graphs of the transmission coefficient versus the frequency of the incident wave are given for various parameters of the rod. The conditions for self-isolation and reflectionless passage of a wave through an obstacle are determined. It has been established that the frequency of the maximum vibration isolation is located above the frequencies at which the waves completely pass through the obstacle. An expression is obtained for the force due to the pressure of bending waves on a one-dimensional object. Its constant component is calculated, which vanishes (for a homogeneous plate) in the absence of waves reflected from the obstacle. It is shown that in degenerate cases the results obtained coincide with previous studies by other authors.

The article presents the results of an experimental study of the structure and strength properties of a heat-resistant nickel alloy of the CrNi65CoMoWAlB grade. This alloy is used for the manufacture of rotor blades for turbines of gas turbine plants. Ensuring the reliability of highly loaded parts is an integral part of the production process. For analysis, samples were taken with different structural states, which were cut from two different batches of blanks for the manufacture of rotor blades. Both batches of billets underwent preliminary hot plastic deformation (forging) and heat treatment (austenization and aging). Samples from the first batch had a reference structure with a uniform distribution of hardening phases, the second batch of samples had a defective structure with a pronounced uneven grain size, stitching and uneven distribution of hardening phases. A detailed analysis of the microstructure and mechanical characteristics of the alloy was carried out both using standard methods and non-standard research methods. Conducting microstructural analysis and relaxation tests using microsamples cut from zones with increased inhomogeneity showed that the standard approach recommended by standard does not reflect the real picture with a negative change in the microstructure of the material and is not sensitive to the presence of microdefects in the alloy structure. The study made it possible to establish the influence of the uneven distribution of hardening phases and inequigranularity on the mechanical characteristics. The limit of microplasticity and long-term strength turned out to be especially sensitive indicators. A significant decrease in the value of microplasticity and time to failure was recorded for a sample with a substandard alloy structure. The detected changes in the structural and strength properties in the material can significantly reduce the performance or lead to failures of critical parts.
Sacralization by the Old Believers of Spatial Loci of Altai
Authors:   Altai State Institute of Culture, Kupriianova Irina
Published: December 2022

This article examines the role and significance of the pre-Christian components of the Old Believer culture in the process of colonization of Altai and the formation of a specific cultural landscape. By renewing the archaic layers of cultural memory, the Old Believers formed the spiritual basis of the colonization process. The basis of this structure was a tradition that accumulates rational experience in the form of a set of stable values, ideas and institutions that can be considered as an important adaptive resource that helps to solve the problems of economic and cultural development of uninhabited territories. This circumstance explains the special saturation of pre-Christian symbols and rituals of the Old Believers' culture in general and the culture of the Old Believers of Altai in particular. The sacralization of its individual components was an inevitable consequence of exceptional life circumstances in which the Old Believers were persecuted and forced to migrate to the outskirts of Russia.

The purpose of the article is to identify the main problems of the transformation of higher educational institutions to the Universitet (University) 4.0 model. The empirical results of the study allowed formulating the main problems of digitalization of domestic education. Socio-cultural transformations caused by deep technologization and digitalization of public life and social relations contribute to the formation of a new model of fourth-generation universities, in which collective and hybrid (human-machine) intelligence will be the key, creating new knowledge, and cognitive technologies forming new approaches will be the key technologies, methods and methodology of education. This, in turn, leads to the transition to mixed learning formats, involving the active use of distance and e-learning technologies in full-time. Digitalization of education requires the development of digital pedagogy: new approaches, tools, teaching methods, and the introduction of new types of classes.

The article briefly describes a role of educational institution of higher education students’ competency in reading in the context of pursuing educational goals. Russian and English-language researchers’ views on reasons of low quality of academic and professionally aimed reading among young people are analyzed. Some factors of unacceptably poor effectiveness of search, selection, interpretation of information undertook by students individually are considered, as well as factors of improper use data took by students from published documents for handling of applied problems. Personally and professionally meaningful consequences of lowering of students’ competency in reading are listed. The authors argue an idea about throwing library specialists at the problem of developing students’ competency in reading through pedagogic technology.
