Published: December 2021

The concept of the embedded genre is of crucial importance if we want to understand the way genres interact, within any given text, within any given genre, and in forming larger genre patterns. By discussing a tentative distinction between three kinds of embedding, “recontextualized embedding” (from Bakhtin), “contextualized embedding” (from Orlikowski & Yates), and “element genre” (from Swales and Martin), the present study initiates an unraveling of some of the intricacies involved in genre embedding. This demonstrates why genre research as well as studies of written communication can profit from integrating an expanded understanding of genre embedding in its theoretical deliberations and analytical work.

Heat supply regulation should ensure high energy efficiency of district heating systems (DHS) in general, reducing the specific indicators of heat production and release and maintaining the normalized thermal regime of the premises with any changes in outdoor temperature, insolation, infiltration and heat. Usually the processes of central regulation of DHS at heat sources and heat consumers are considered separately: not only technically but also organizationally. In this regard, the proposal for joint consideration of central and local regulation of heat supply is relevant and useful. The proposed solutions can increase the efficiency of existing DHS at the stage of transition to modern options for their implementation, in which heat control units are located at the entrance to individual apartments, and thus, the degree of regulation of DHS as close as possible to autonomous heating systems. The purpose of the study is to comprehensively consider the impact of individual stages of heat supply on the overall efficiency of DHS. The most common in domestic DHS is a method of high-quality central control of heat supply by changing the temperature of the coolant in the pipelines of thermal networks at the outlet of heat sources. However, this method has a significant disadvantage - it is inefficient regulation during the period of cutting the temperature schedule with a joint load on heating and hot water. Working during this period leads to significant overheating in premises and unproductive heat loss. Unproductive heat losses because of inadequate regulation when lowering the heat release schedule reach up to 18% of the heat potential of the fuel used. The introduction of a combined quantitative and qualitative regulation is proposed, in which, up to the cutoff temperature of the temperature schedule, the heat release is controlled by changing the temperature of the coolant, and after the cutoff, the transition to quantitative central regulation is carried out. Practical recommendations for the implementation of such regulation have been developed. Combined central regulation ensures the possibility of providing hot water supply services throughout the entire heating period, avoids hydraulic and thermal deregulation of systems and ensures optimal conditions for the operation of heat generators, reduced energy consumption and a significant increase in the overall efficiency of the DHS.

When assessing the thermal condition of the building and the parameters of the microclimate of the premises, the main factors influencing its thermal inertia were identified and taken into account. An assessment of the influence of the resistance of enclosing structures on the efficiency of the heating system, taking into account the influence of external and internal climatic parameters in the dynamic mode. It is shown that the time factor and depth of regulation, as well as the outdoor air temperature are important factors. Researches are carried out and the expediency of introduction of a duty mode of heating of buildings of HIGH SCHOOLS is estimated. The given algorithm of control of process of heat release (especially in the presence of a point of "breaking" - average (them) on the schedule) in addition increases accuracy of the decisions of the specified problems and reduces a temperature deviation by 4 ÷ 6 ° C in comparison with usual ("linear") dependence that allows to correct more precisely release of the heat carrier in system of heating of a structure at introduction of a standby mode. It was found that it took about 6.5 hours to achieve normalized air temperature and space heating in the forced (after a long stay on duty). It is shown that the heat consumption of the system in such conditions of its operation compared to the nominal mode increased by 25 % (taking into account the limit value of the specific allowance from table H1 DBN B.2.5-67: 2013 "Heating, ventilation and air conditioning"), but for the entire period the action of the standby mode savings amounted to about 6-8% of energy consumed. Taking into account the design of the outer walls of the object of study, the temperature graph of the heating system was adjusted taking into account the value of the internal heat capacity of the building when implementing on-duty heating, which, according to preliminary estimates, will: improve comfort in the room; to reduce heating costs of the educational and administrative building of NULES of Ukraine by 10-12 % for the heating period.

Published: December 2021

The motion of material particles on gravitational surfaces, ie the motion of particles on surfaces under the action of its own weight, is used in special devices for their separation by physical and mechanical properties. For this purpose stationary screw surfaces of a steady step are applied. A number of papers have now considered the relationship between the kinematic parameters of motion, the coefficient of friction and the design parameters of the separator, when its surface is a deployable helicoid. The purpose of the study is to investigate helical surfaces with different design parameters in order to improve their separation ability through mathematical and geometric modeling of the process without making surface models. The problem of finding the trajectory of a material particle on the surface under the action of its own weight is preceded by the problem of finding the trajectory on an inclined plane. If a material particle with a certain initial velocity vо and a certain angle of inclination to the horizon falls on an inclined plane, it will move along a certain curve (in the absence of friction and air resistance, the trajectory will be a parabola). A system of equations is obtained, which describes the motion of a material point on the gravitational surface in the general case. If it is created for a specific surface, nonlinear and numerical methods must be used to integrate it. Modern software products allow not only to find the trajectory of the particle, but also to show it on the surface and even make an animation that essentially replaces high-speed shooting. This approach makes it possible to study the kinematic parameters of motion on different helical surfaces without full-scale samples of these surfaces, which significantly reduces the cost of finding the right surfaces. The motion of particles along a helical conoid and a deployable helicoid is considered. Simulation of the motion of a material particle on helical surfaces and its study by modern means of numerical integration and visualization have shown that for different surfaces the nature of the motion of the particle will also be different. When moving on the surface of the helical conoid, the particle in the presence of friction first accelerates, and then stops at a considerable distance from its axis. To prevent this, you need to take a limited compartment of the conoid both in height and on its periphery. When a particle moves on the surface of a deployed helicoid, its velocity becomes constant over time, and the trajectory after that will be a helical line.

A promising alternative energy source is biogas, which is obtained by bacteria processing an organic substrate without access to oxygen. The efficiency of the use and functioning of technological systems is determined by the indicators of their operability and reliability. The aim of the study is to develop a methodology for assessing the performance of technological systems for biogas production by complex indicators. The article analyzes the methods of complex assessment of the state of technological systems. The considered methods have the following disadvantages: most of them can be used only after a certain operating time of the system; expert assessments are based on intuition and, as a result, are not always objective; the functional-parametric approach is methodological rather than practical; determination of the efficiency retention coefficient with an increase in the number of elements and the complication of the structure of the technological system becomes rather difficult. The operability of technological systems for biogas production with an increase in their service life is expressed through a change in technical condition indicators, a decrease in productivity and a change in economic indicators: an increase in costs per unit of work performed and additional costs for maintaining a repair and maintenance base. To analyze the technical state of technological systems for biogas production, it is advisable to use a complex operational indicator , which simultaneously takes into account its technical and economic characteristics during the period of operation, that is, the unit costs of ensuring operability through the cost of a unit of production during the service life up to the limiting state.

The article considers the issue of studying the value of pH, substrate in the process of methane fermentation in the mesophilic regime and the influence of the electromagnetic field of industrial frequency. The aim is to investigate the influence of electromagnetic fields on the pH value of the substrate during fermentation. Different types of microorganisms are involved in the process of methanogenesis, and the decisive role in it is played by methane-forming archaea, which are most sensitive to pH and should be in the range of 6.5 - 8. Therefore, it is necessary to check the effect of low frequency electromagnetic field on substrate pH. The study was performed for 25 days on two substrates, one of which was exposed to a low-frequency electromagnetic field with an electromagnetic induction of 3.5 mT. The research results show that the pH value of the substrate exposed to the electromagnetic field during the methane fermentation process was within acceptable limits, and the second substrate decreased, that is, it was acidified.

The paper is devoted to the analysis of the software life cycle of engineering objects. To implement the processes and relevant procedures aimed at ensuring, as well as maintaining proper management of the level of software quality at the stages of the life cycle, it is proposed to use the life cycle model as a methodological basis for achieving the goal - achieving the proper level of consumer quality of the final product, taking into account the conditions and circumstances. exploitation.. The considered model of the life cycle in the framework of software engineering is a structure that determines the sequence of implementation and relationships of processes and procedures of a different nature that may arise when performing any actions in relation to software, from the emergence of a need for this software and ending with its final withdrawal from use. If necessary, the life cycle model has a relationship with the content, scale and complexity of the corresponding project, on the characteristics of the conditions and circumstances under which a particular software is created and operated. At the same time, the existence of a life cycle model, carefully developed at the same time, adequate to the existing conditions and circumstances, is the basis for the implementation of general quality management within the framework of a program project, which at this point in time is stipulated as a methodological basis for obtaining a project at the output of an object that meets the presented requirements and modern quality standards. The main reasons for the need to pay special attention to modeling the life cycle of the software being developed and the component of the environment surrounding the software at different stages of its life cycle, taking into account the life cycle of material engineering objects, are presented. Taking into account the presented concept of the life cycle implementation in some virtual enterprise, the software sequentially performs the transition from one state to the next, from consumer properties specified by the customer to an already finished software product and quite real consumer properties supported by the corresponding characteristics, this software is in operation to moral aging, and also goes into a state characterized by the modernization or removal of this software from use.

Published: December 2021

The study highlights methodological aspects of predicting stem volume of merchantable Scots pine trees by grade categories using distribution models of different quality zones along stems. The study is based on empirical data collected in the mature stand during clear-cut harvesting. In total it includes measurements of 245 tree stems for which sequence and lengths of different quality categories were evaluated. A semi-Markov model was applied to characterize a random process of height-relevant co-occurrence and length of merchantable wood, firewood, and residues. The model was determined by the following parameters: 1) input occurrence probabilities of specific grade category in the butt section of tree stems (initial state of the system); 2) distribution matrix of grade categories by lengths; 3) matrix with transition probabilities between grade classes on different stem heights. In this study, we considered the process in which the initial state of the system was associated with merchantable wood which was true for most pine stems. We used beta-function to model lengths of grade categories which parameters were fitted using relative stems height. We also used empirical data to calculate probabilities of transition between merchantable wood, firewood, and residuals along pine stems. The analysis indicates that the length distribution of merchantable wood and firewood depends on the relative height where the grade is observed, and total tree stem height. Thus, we identified four zones where the function of beta-distribution was used to model lengths of each grade category with customized parameters depending on the relative height of their location on tree stem. As a result, we developed a methodology that can be used to simulate datasets with tree stem characteristics, and further to predict the distribution of volume by grade categories depending on their diameters, heights, and merchantability. It is worth noting that our study is focused merely on merchantable pine stems, and one should expect another relationship for stems of different tree species as well as for merchantable pulpwood trees. Given the new standard for merchantable wood classification adopted in Ukraine, the developed methodology is suitable for updating existing tables of distribution of tree stem volumes by wood grade categories.

Recent studies show an increase in the number and frequency of catastrophic forest fires in the world since the end of the XX century. Such forest fires often will cause essential economic and environmental losses, human casualties. According to forecasts, in Ukraine due to climate change fire weather danger will steadily grow: temperatures rising, changing seasons duration, prolongation of the vegetative and fire season, increasing the frequency and intensity of heat waves and natural hydrometeorological phenomenon, change of local water patterns. Several catastrophic fires in the natural landscapes of Ukraine occurred in 2020 in different regions of the country. Wildfires in Zhytomyr, Luhansk, Kharkiv and Kyiv regions were the largest and most catastrophic in Ukrainian history, with human casualties, large economic losses, environmental and social negative consequences. The main parameters of such catastrophic fires weather conditions, long period without precipitation, high air temperature and wind gusts of 15-25 m/s. There are two main critical periods in Ukraine, in terms of frequency and risk of forest fires. The first, spring, from the melting snow to the regeneration of a new green cover. The second period lasts from the last month of summer into the autumn rainy season when agricultural vegetation dries up and people and farmers use fires for remnants of vegetation clearing in the fields. The catastrophic landscape fires of 2020 indicate the gaps of the current fire management system on natural and cultural landscapes in Ukraine to effectively respond to large fires. The current system needs enhancement in accordance with new conditions and challenges. The manuscript presented information about catastrophic fires that occurred in the natural landscapes of Ukraine in 2020 based on available official information, remote sensing data and data from the geoportal "Landscape Fires of Ukraine" (wildfires.org.ua). Also in the article, performed the analysis of the components of the current fire management system and the main shortcomings and key recommendations for its improvement are formulated.

Green plantations of ancient park not just only an important ecological component of human habitat, but also a cultural and historical factor of national identity. The history of Ternopil landscape art demonstrates the close links of Ukrainian culture with Polish, Lithuanian and Western European. Galicia is rich in architectural monuments of the past: fortresses, castles, defensive ramparts, courtyards, fortifications, fortified monasteries and temples, estates and manors of the local nobility. Decorative parks, orchards, and collections of medicinal plants were established near such buildings. Most of the ancient parks have undergone significant negative changes due to turbulent historical events in the twentieth century. But some objects, although in a state of disrepair, have been preserved and need to be restored and maintained. Skala-Podilsky Park, a monument of landscape art of national importance, was founded at the end of the 18th century. In the future, this park was repeatedly reconstructed. During that time, many ornamental, fruit, berry trees and shrubs, including exotic ones, have been acclimatized here. During the period of Ukraine's independence, proper care of plantations was not carried out. Such way brings the destruction of the park's infrastructure and a reduction in the number of valuable taxes. A tax inventory of dendroflora was carried out to organize the territory and reconstruct the park-monument. The vital and phytosanitary condition of trees and bushes was determined there according to the Alekseev scale. 63 species of trees, bushes and vines were found during this research. It is established that the general indicator of relative living condition of park plantings makes 57,7% and corresponds to a category "weakened". According to the phytosanitary condition of trees and shrubs, 41% belong to the category of "satisfactory", 34% - "good", 25% - "unsatisfactory". Thus, a quarter of the registered trees need to be rehabilitated or removed from the stand. The received materials testify to the need to conduct counting and inventory of all ancient parks of Ukraine and to develop a system of their geoinformation monitoring in order to streamline revitalization.

Authors: Dzyba А. А.
Published: December 2021

Theater as a place for spectacles is a form of social consciousness, a means of ideological and aesthetic education of the population. Theater reflects the peculiarities of the development of society and is related to its culture. The desire in different periods to harmoniously combine nature and culture, green theaters, and other green scenes has always reflected the tastes and fashions of a certain era. The history of the development of garden theaters in the European countries, including Ukraine, is considered. The types of theaters on the territory of historical gardens, parks, estates, palace and park complexes, and garden and park ensembles of Europe and North America of the XVII-XX centuries are studied. The history and evolution of the development of the main types of theater buildings are characterized and their differences are given. The preconditions for the emergence and popularization of open-air theaters have been clarified. The terms - garden, green, air, summer theaters - are analyzed and generalized. Based on the research, the classification and definition of a garden theater (amphitheater) are proposed. Garden theaters are types and varieties of theaters (forest, landscape, green, air, water, summer, stone, mechanical, palace) and amphitheaters (stone, lawn), located on the territory of gardens, parks, garden and park ensembles. They can be open-air (temporary), closed (permanent), combined (cooperation of temporary and permanent theaters). On the territory of gardens, parks, garden and park ensembles, several types or varieties of theaters or a theater and an amphitheater can be located, the amphitheater can be part of a theater. A comparative analysis of green, water theaters and other theaters is given. The characteristic features of the location of theaters in the planning structure of the studied objects, including elements of topiary art and an assortment of plants for green, water, air, and summer theaters, are revealed.

Authors: Demchenko O. O.
Published: December 2021

The research was conducted on the structure and characteristics of the growth of shoots of the genus Viburnum L. There are significant differences in the structure and dynamics of growth within the genus, so the determination of the structural features of the shoots of species of the genus Viburnum is relevant. The research of the dynamics of shoot growth was carried out according to the method of A.A. Molchanov and V.V. Smirnov (1967). The species studied by us belong to three sections of the genus Viburnum; the peculiarities of buds structure generally determine the structure of the shoots in the species of each section. It was found that the type of each of the three sections of the genus is characterized by a special structure of the shoots. It has been studied the rhythm of growth and development of native and introduced species of the genus Viburnum L. The terms of shoots growth of the species of the genus were analyzed, and the length of the annual growth of shoots was determined. Phenological date of the beginning and end of shoot growth was established. It was revealed that the onset of individual phenophases quite clearly correlates with the sum of effective temperatures above 5 ° C. The species of the genus Viburnum are characterized by the following types of shoots: tillering, stem, generative. Intensive growth of shoots of all studied species occurs in May - mid-June. In the species of the section Lantana, there are 2 peaks of shoot growth - May and mid-July. According to the duration of growth of shoots, viburnum can be divided into two groups: 1) with a short period of growth (65 - 75 days): V.opulus L., V.sargentii Koehne, V.prunifolium L., V.rufidulum Raf., V.lentago L; 2) with a long period of growth (100 or more days): V.lantana L., V.carlesii Hemsl., V.veitchii C.H. Wright, V.rhytidophyllum Hemsl., V.buddleifolium C.H. Wright, V.burejaeticum Rgl. et Herd. The data obtained demonstrated that the greatest annual growth of all Viburnum species was recorded at the age of 4-7 years. A decrease in the annual growth of axial shoots states the need for works on preliminary rejuvenation of the bush.

The theme of this article focuses on the various (and contradictory) measures to deal with the disastrous consequences of the Covid-19 pandemic, that is, on the one hand, by encouraging the immediate resumption of Tourism leveraged by the current administration of the Federal Government of Brazil (such as a strategy to fight the economic crisis) and by protest actions by representatives of the productive sector of Tourism and, on the other hand, by popular demonstrations by residents of Brazilian tourist destinations, against such a resumption of the activity. So, the central question seems to be: how should national public policies be structured in order to mitigate the appalling negative impacts of the pandemic on the Brazilian economy (especially regarding unemployment and lack of income), without disregarding the fundamental commitment to health security of populations in tourist destinations, in view of the increase in the situation of disseminated contamination? The objective of the research is to analyze the contradictions that have been established between national public policies for the resumption of Tourism (in the fight against the economic crisis resulting from the Covid-19 pandemic) and the growing insecurity of populations in Brazilian tourist destinations in view of the expansion of the situation. of contamination. The theoretical foundation is based on: theories of the sociology of absences and emergencies, by Boaventura dos Santos; Hannah Arendt (2010) about the rise of the social sphere that undermined the original distinction between public and private, with action (praxis) being one of the fundamental human conditions. The theoretical-methodological path taken in the development of the essay is the multiple case study through the analysis of experiences, and the triangulation of speeches through analytical categories. The discussions that open from there permeate conceptual debates on an ethical foundation of public policies, to mitigate the effects of structural crises, and the current impact of the pandemic that devastates the world scenario. And if these are in the field of mitigation or irresponsible promotion, under the commitment to save jobs, opposing ethical attitudes in the exercise of imposing violence of legal authority, and the principles of public discussion on "mutual commitment and common deliberation".
“Civilization” As a Local Phenomenon: The First Stage of Theoretical Study
Authors: Ilinskaya Svetlana
Published: December 2021

The author examines the first stage of theoretical research of the concept of “local civilizations”. Nowadays this approach protects the right of non-Western communities to  independently and authentically define their way of development. If  non-Western macro-regions accept the understanding  of civilization as a universal phenomenon, their development will be determined by Western experience.
In case those non-Western regions (and Russia as well) are seen as distinctive civilizational formations, their right to determine the ideal social/state structures and future development for themselves is recognized. 
The stage of classical comprehension was overshadowed by the crisis of the imperial form of existence of large geopolitical spaces and was an attempt to formulate new foundations of their identities. The article reviews the ideas of N. Danilevsky, O. Spengler, A. Toynbee and P. Sorokin. The author also evaluates the heuristic potential of the methodological approaches by the scholars of the fundamental wave.
Problems of The Antarctic Treaty System (Political and Legal Aspects)
Authors:   Primakov National Research Institute of World Economy and International Relations, Russian Academy of Sciences (IMEMO), Gudev Pavel
Published: December 2021

The article considers the key factors that affect the stability of the Antarctic Treaty System (ATS), erode its basic norms and provisions, lead to strengthening of political and legal contradictions between countries and, in general, to a prospective strengthening of interstate conflicts. Among those factors are the attempts of some claimant states to form maritime zones of sovereignty, sovereign rights and jurisdiction in the Antarctic waters and the process of defining the outer limits of the continental shelf within the framework of the Commission on the Limits of the Continental Shelf initiated by them. The author shows how justifying their actions with references to the rights and powers granted to them under modern international maritime law, and above all the 1982 UN Convention on the Law of the Sea, leads to an imbalance of the entire System. The unresolved questions concerning the applicability of the concept of common heritage of mankind (CCH) to the Antarctic, the legality of the formation of maritime zones around the sub-Antarctic islands and restrictions on the exercise of national jurisdiction on the continent itself increase pressure on the sustainability of the established legal regime. It is in the interests of the Russian Federation not to allow the complete destruction of the established system of governance, and if it is inevitable, to be ready to pursue an active policy to defend its national interests.
Methodology of the National Maritime Potential Quantitative Assessment
Authors:   Primakov National Research Institute of World Economy and International Relations of the Russian Academy of Sciences (IMEMO), Polivach Alexander P.
Published: December 2021

This article analyses methodological issues which emerge in case someone attempts to make a comparative quantitative analysis of the overall maritime potential possessed by various countries. The author suggests possible solutions for those problems and also proposes a system, which can help to make an assessment of countries’ capabilities to have control of the sea, to exercise jurisdiction over the sea zones and to use the sea for a variety of their purposes. This system forms the index of maritime power of a nation, which is an overall quantitative expression of these capabilities. The overall index is based on four sub-indexes: maritime resources, maritime instruments, navy, maritime activities.
Intellectual Data Mining in Socio-Geographic Research
Authors: Blanutsa Viktor
Published: December 2021

In social geography, aimed at understanding the territorial organization of society, various methods are used, including data mining. However, there is no generalization of the experience of using such methods in world science. Therefore, the purpose of this article is to analyze the global array of scientific articles on this issue to identify priorities, algorithms and thematic areas with their capabilities and limitations. Using the author's method of semantic search based on machine learning, about two hundred articles published in the last two decades have been identified in eight bibliographic databases. Their generalization made it possible to identify chronological and chorological priorities, as well as to establish that a limited number of algorithms had been used for the geospatial data mining, which can be combined into groups of neural network, evolutionary, decision trees, swarm intelligence and support vector methods. These algorithms were used in five thematic areas (spatial-urban, regional-typological, area-based, geo-indicative and territorial-connective). The main features and limitations in each direction are given.
Labor and Attitude To It: Before and After Modernity
Authors: Shipilov Andrey V.
Published: December 2021

The article examines  the problem of the changing nature of labor and attitudes towards it. The relevance of this topic continues to grow due to current trends in socio-economic development. The author draws attention to the fact that only in the industrial society, which was formed in Europe of the XIX century as result of the industrial revolution, labor was seen as the ability, need and duty of a person, as something that did and makes him a person. The positive value status of labor persists to some extent even today, but the industrial society has ceased to exist due to the overflow of labor force from industry to service. This overflow happened because of the increase in working efficiency. In the postindustrial society the process of a general reduction in labor in favor of leisure is unfolding as the value of the latter increases and the value of the former decreases. In this regard, it is useful to remember that in the agrarian society, as well as in the era of Antiquity and the Middle Ages labor was viewed as an anti-value and was the occupation of the lower classes and estates. The attitude towards labor in the post-industrial era approaches the attitude of the pre-industrial period, turning from positive to negative, while leisure becomes self-valuable and self-sufficient. Thus, one can agree with the opinion that the civilization of labor is being replaced today by the civilization of leisure.
