Using space syntax measures to assess the human impact on ground cover plant communities in recreational forests
Authors: Kryukovskiy A , Kupriianova A , Melnichuk I , Smertin V 
Published: October 2020

Abstract
This study used space syntax theory to predict the recreational impact on natural forest ecosystems. We assumed a correlation between specific space syntax measures and parameters that describe the recreational impact on forest ecosystems. For constructing a model of spatial structure of recreational forest, we chose an angular segment map of a road network. Most of the recreational impact is caused by trampling which we used to evaluate the visitors traffic. Field observations of ground cover were made on transects. For the road network we used the natural logarithm of the T1024 Choice measure, called LNchoice, and divided the range of values into two subsets. The subset ‘zone 0’ included segments where LNchoice was lower than the mean value of LNchoice, while the subset ‘zone 1’ included all other segments. Comparative analysis of the field data and indicators of the road network confirmed that zone 1 had higher trampling impacts than zone 0. In zone 1, degree of coverage by typical forest plants and their degree of dominance were lower than in zone 0, and the percentage of dead ground cover was greater. These results show that space syntax theory has great potential for landscape design and management of recreational forests.

Published: October 2020

Abstract
The differences arising in the analysis of the throttling process in different reference systems are considered. It is shown that it is convenient to analyze the change in internal energy when throttling a certain volume of gas in a system of counting that is rigidly connected to its center of mass. In this system, gas expansion works, resulting in energy being diverted to the environment. At the same time, energy is transferred from the environment to the gas by the movement of the throttle device. The sign of the increment of the internal energy of the considered volume of ideal gas in the non-equilibrium process adiabatic throttling is determined by the ratio between the two named energy exchange processes. From the first law of thermodynamics, an expression is obtained for the value of the increment of specific internal energy when throttling an ideal gas.

Abstract
The analysis of the irreversible process of adiabatic throttling of an incompressible liquid using the construction of physical and mathematical models of the process is carried out. The nature of irreversible dissipation of mechanical energy in the fluid flow is revealed. An analytical expression is obtained for the always positive so-called specific heat of friction, the value of which depends on the nature of the flow. This value can be equal to zero only in the case of a vortex-free or helical movement. Therefore, only with such movements, the mechanical energy of the flow does not dissipate.

Abstract
The Paris Agreement is the legal basis for the current stage of regulation of greenhouse gas emissionsaimedat preventing further climate change. The Russian Federation has declared its national climate commitments taking into account the carbon absorption capacity of forests. It has been established that the current stage of development of the national economy is accompanied by an increase in greenhouse gas emissions, which will require additional measures to implement Russia’s climate policy. The article assesses the contribution of the Russian forestry to the fulfilment of the national obligations under the Paris Agreement. A negative tendency towards reduction of carbon sequestration in Russian forests has been revealed. As the main factors influencing the dynamics of greenhouse gas emissions and their absorption in the forest ecosystems, the study identified forest fires, logging activities and the scale of reforestation. The article substantiate the expediency of the development of forestry as a condition for the implementation of the climate policy of both the country as a whole and its business entities. By implementing forest projects aimed at compensating for greenhouse emissions, representatives of the Russian business will be able to avoid the risks of losing the investment attractiveness of their enterprises and reducing the competitiveness of their products in international markets.

Authors: Lobovikov M , Pryadilina N 
Published: October 2020

Abstract
Branch and regional prioritization of the forest sector is a necessary condition for its development and compatibility growth. It allows toplan and forecast the forest management activities and their allocation across the country. Strategic planning and forecasting should use the following methodology. Firstly, it is necessary to rank the priority branches of the forest sector according to the criterion of their income (for example, wooden housing construction, packing paper, furniture, bioenergy, etc.). At the next iteration, economic regions are to be ranked according to the transportation cost criterion (for example, North-West, West, Center of Russia, Siberia, the Far East etc.). Merging both iterations in a single matrix will show the direction of diminishing effectiveness of the managerial solutions. The most effective solutions will be in the upper left corner of the matrix. The least effective solutions will move to the lower right corner. This matrix should serve a conceptual basis of the methodology for the long-term strategic planning and forecasting of the forest sector in the Russian Federation.
The problem of integrity in the context of quantitativistic and qualitativistic research programs competition in biology
Authors: Lubomirov D E , Petrov S O , Sapenok O V 
Published: October 2020

Abstract
The article considers the role of biological knowledge in the formation of modern holistic worldview, developed in the framework of global evolutionism, which has been established within the post-nonclassical scientific rationality. The studies of material in the history of science and the history of philosophy, as well as the works of modern authors, revealed the existence of contradictory quantitative (quantitativistic) and qualitative (qualitativistic) research programs in the development of knowledge and its worldview interpretations, which alternately claimed to dominate in science. On the basis of retrospective analysis of the science of living it is shown how the development of a qualitatively-holistic approach in biology helped to overcome the principles of reductionism and to what extent it can contribute to the introduction of significant adjustments to its methodology. The authors made an attempt to identify and justify a special role in this process of evolutionary and environmental studies, which serve as the basis for the formation of new promising theoretical and methodological programs based on the principle of integrity. The scientific novelty and relevance of the article consists in explicating on the biology material the heuristic and methodological significance of qualitativism as a cognitive-methodological approach in comprehending biological processes.

Published: October 2020

Abstract
Making (identifying) the right decision, just making a decisionis a choice from a variety of acceptable alternatives, depending on various factors, one in which the effective value is optimized. If a decision maker (DM) or a decision support system (DSS) can isolate a control parameter with unconditional preference that is relevant and most fully characterizing the properties of the system (process, object), it can be considered an objective function, subject to certain restrictive (by an acceptable set, resources) conditions. A similar problem is single-criterion, solved by classical methods of the decision theory. Decision-making tasks can be solved by a sequence of steps, a procedure: generation of acceptable options, selection of relevant criteria, search for an acceptable choice, its evaluation. In solving the problems of the decision support system (DSS), the decision-maker is usually involved - an expert, an analyst with competencies in the subject area and evaluating options, a consultant who helps to formulate acceptable options. The article discusses the development of a conceptual model of a geographic information system to support managerial decision-making. The basis of such GIS is an automated mapping system.

Published: October 2020

Abstract
The population’s demand for recreational services tends is growing steadily, the amount of growth varies depending on objective and subjective factors. The problem of economic assessment of forest recreation can be solved only after the recognition of recreational services and their inclusion in the economic relations between the state, the population and private business. Economic estimation of the recreational function of forests will help to scientifically justify the amount of damage to be compensated for damage caused to forests by industy, institutions, organizations and citizens. Recreational function can be attributed to natural resources, since it has a potential value. In market conditions, it is the final consumer of recreation-the population-that should evaluate the recreational function. The size of this theoretical payment revealed in the course of the study allows us to judge the value that the recreational function of forests represents for the state and the population. The inclusion of recreational services in economic relationships will allow to get an independent and objective estimation of the recreational function of forests.

Published: October 2020

Abstract
Research of the food and minor resource potential of the Russian forest and market demand for these products has been done in the article. The objective of the work is to show an imbalance between the huge potential of food and other non-timber products and the limited demand for such resources. The subject of study is economic results of food and minor resources consumption of the Russian forest. The novelty of the research is that regularities are identified and development trends of demand for food and secondary resources of the Russian forest have been assessed. The demand is formed by supply and demand, on the one hand, by the national management system, forest legislation, traditions and customs, on the other. Harvesting centers of food and secondary resources of the Russian forest are shown. Measures are proposed to increase the efficiency of the use of food and minor resources of the Russian forest. The research results can be used by forest companies, scientific organizations. The research can be continued towards the inclusion of food and secondary resources of the Russian forest in the economic relations system in forestry at national and international levels.

Abstract
The possibilities of the use of geoinformation systems (GIS) for green areas managing were discussed. The features of the use of the Field-Map software and hardware complex on landscape architecture objects are given. Field-Map allows you to perform mapping of any object in real time, estimate distances and areas, create thematic maps, perform dendrometric measurements, i.e. use all the features of a full-featured GIS directly when working in the field. The GIS of urban garden and park objects on the example of the city of Simferopol (the Republic of Crimea) were demonstrated. It seems promising to perform a planned inventory of urban green spaces of municipalities with mandatory GIS of plants collections of introduction points can contain an unlimited number of attributes, which allows to enter into a single database information on the time, origin and sources of receipt of the plant sample, the type of planting material, estimation of frost resistance, drought resistance, disease and pest infestation, the beginning and duration of flowering or fruiting, the period of greatest decorative effect, and other features. The work on creation of GIS arboretum and scientific exhibitions were conducted in N V Bagrov Botanical garden of the V I Vernadsky Crimean Federal University.

Abstract
Robinia (Robinia pseudoacacia L.) is known for high honey productivity: in Ukraine, in Romania it is 600-800 kg, in Nonblack soil area it is up to 360 kg from 1 ha of a continuous forest stand.According to observations of the scientists, a bee family can collect up to 8 kg of honey under favorable weather conditions from a Robinia tree, and under adverse weather there were from 4 to 6 kg of Robinia honey in strong families at the apiary.The task of our study was to determine honey productivity of Robinia depending on locality, exposure and the slopesteepness. Optimum forest vegetation conditions for maximum nectar emission by Robinia flowers were defined. A number of methods defining taxation indices, sugar content in nectar, blooming intensity and honey productivity was used to solve the assigned tasks. Carried out comparative analysis of honey productivity indices showed that local topography influences the blooming terms of plants and nectar emission. So, the most productive locality for beekeeping is locality with gulches. It provides the best honey yield under favourable meteorology and forest vegetation conditions.

Abstract
The surface roughness of wood products has a direct impact on many technological and operational properties of parts as a whole and is an important production factor, which is associated with the consumption of materials and the technical and economic efficiency of many technological operations such as gluing, grinding, varnishing, etc.We must not forget about the aesthetic properties of wood - reflective and absorbing ability, which is directly affected by surface roughness. The urgency of the problem of obtaining the required quality of the treated wood surface is now becoming increasingly important in connection with the increasing requirements for the quality of woodworking products and obtaining the greatest economic effect for the enterprise. A polished surface is formed as a result of the simultaneous action of many factors. The main ones are geometric factors, plastic and elastic deformations that accompany the grinding process.From a geometric point of view, the roughness is created due to the copying of the path of the cutting tool of a certain geometric shape on the wood surface. Plastic and elastic deformations occurring during the cutting process strongly distort the microrelief resulting from the action of geometric factors.

Published: October 2020

Abstract
The purpose of this publication is to generalize the available experimental data on the survival, growth, stability, technical and other characteristics of this hybrid and to clarify proposals for its practical use. Long-term studies have been carried out on the five variety testing sites in various soil and climatic zones of the South-Eastern part of Russia and in Ukraine. The survival rate of this poplar were quite high (from 75 to 96%), on average 81%. The age of economic exploitability in the forest-steppe zone with a 20 m2 feeding area per tree was equal to 29 years. To this age the ‘Voronezh Giant’ accumulated stem wood stock of 550-640 m3/ha. The duration of shoot growth was 146 days, and the growing season was 177 days. It was distinguished by high winter hardiness, relative drought resistance, wind resistance, low damage by primary and secondary entomopests, and affection with phytodiseases, but a low straight trunk. It has a fairly high timber density, the length of the wood fiber and the cellulose content, which is important for the pulp and paper industry. The freshly picked green leaves of this poplar are close to the nutritional value of meadow herbs and lucerne. In general, the poplar ‘Voronezh Giant’ is promising for growing wood pulp, introducing into energy, shelter-belts, roadsides, riversides and other reclamation plantings. Given into account its male gender and high decorativeness, it can be also recommended in the greenery landscaping.

Published: October 2020

Abstract
Global environmental changes and increased consumption of forest resources require special attention to forest exploitation. The relevance of studying the role of forest hunting in solving the problems of exploitation and regeneration of forest resources is justified by the need to switch to sustainable forest management, increase the biological stability and productivity of forests, strengthen water and soil protection, and ensure sanitary, recreational and other benefits of forests. The article substantiates that the future development of forestry should be based on the principles of sustainability; that is, in the process of regeneration and development of forests, environmental, economic and social goals should be taken into account. We have formulated the tasks and the role of forest hunting enterprises in forest exploitation. As structures engaged in integrated economic activity, forest hunting enterprises, with a rational approach, are able to reduce the risks of forestry activities and ensure environmental, economic and social effects. We have clarified that these effects can only be obtained if the balance between environmental, economic and social components of the sustainable development model is ensured. We have formulated the basic conditions that will allow forestry enterprises to carry out their tasks with maximum efficiency.
