Published: April 2020

Abstract
The authors discuss effectiveness of use of land resources for the agricultural sector in the Sakha Republic (Yakutia) and substantiation of the need in evaluating effectiveness thereof. They analyzed the contemporary condition of the republic’s land resources and of the main sectors of industry in the countryside - agriculture. The authors also analyzed the interconnection of the primary agricultural indicators and the quality of land resources. The results demonstrate a rather low effectiveness and negative trends of primary indicators. Therefore, the need in evaluating effectiveness of use of land resources is substantiated. Also, there is a need in improving effectiveness of use of land resources in agriculture at the present time by means of continuous intensification.
Transactional Analysis of Agrarian Sector

Abstract
The Russian agrarian market shows a difficult situation. We research this market with the institutional point. The food chain is rather long. We can see the following subjects: “farmers – manufacturers – wholesale merchandisers – retailers – ultimate consumers”. We can’t deny “egoistical” motive of each subject to increase his own utility (and this idea is under the neoclassical paradigm). If we speak about the first four subjects, this utility is in the desire to sell the product to the following link in a chain at higher price. We can consider such desire normal if the price extra charge at each stage of the agrarian chain doesn’t exceed on average 5% over the cost value (in one of the reports the President of Russia has said such trade extra charge as “normal” profitability for food sellers). Meanwhile, we see an essential distortion at the stage “farmers – manufacturers”. We suggest to consider this phenomenon through the institutional theory which operates with categories “contractual relations”, “behavioral opportunism”, “transactional costs”. The companies- manufacturers often hold a monopoly position at the local markets. As a result farmers have no opportunity to realize a product at reasonable price. Thus, production of a qualitative, environmentally friendly and healthy product becomes almost impossible. Farmers have no motivation to produce a qualitative and safe product, and in general to produce it. The efficiency of contractual interactions of a food chain is low already on start. Thus, researching the agrarian market since 2015, we have come to a conclusion concern such phenomenon as “a transactional rent”. This category has been introduced for scientific use. Using this category we point to the institutional imperfection of the agrarian market. More over in the article the we make quantitative analysis using developed technique. It allows to estimate the level of transactional costs at each stage of food chain.
Evaluation of the Impact of Climatic Changes on the Development of Agriculture of European North Russia
Authors: Druzhinin P , Potasheva O 
Published: April 2020

Abstract
Observations indicate that global warming may be currently taking place, which has accelerated markedly since the 1970s. Research on the implications of climate change has shown that the greatest effect is to be expected in the following sectors of the regional economy: agriculture, transport infrastructure, utilization of coastal resources, energy, forestry, tourism, fish industry and water. Studies for Russia, which is overall a relatively cold country, showed that climate change has a direct effect on production in agriculture and it may be either positive or negative in different regions of the country. To assess the effect of climate change on agriculture in European Russia we distinguished climatic zones with similar temperature and precipitation values. Several models of the dynamics of agricultural production and yield depending on climatic characteristics, farming practices and socio-economic characteristics were built. As a result, the positive impact of climate change on crop yields in Russia has found only partial confirmation. A greater effect can be manifested by increasing the level of management and transition to modern technologies, and gradual shift to the north of grown crops. This will accordingly require increased investment in agricultural science to implement new projects in line with the changing external environment.
Features of Machine-Technological Stations Organization in the System of Agro-Industrial Production
Authors: Terentyev S E , Gnezdova J V , Semchenkova S V 
Published: April 2020

Abstract
The creation of modern machine-technological stations (MTS) causes a lot of disputes about the effectiveness of their operation. The majority of MTS are commercial enterprises, independent of services consumers, which, in the conditions of decreasing equipment availability of agricultural producers, turned out to be monopolists comparing with them. Agricultural enterprises could not become founders of MTS and do not have the ability to influence on the activities of service enterprises directly. The efforts of the stations are greatly aimed to get their own profit and much lesser to increase the efficiency of served arms. Many experts have the opinion that the achievement of economic well-being of MTS often is due to the decreasing of the economy of services consumers.
As a result of the direct economic effect of the MTS activity - the profits of agricultural producers are not yet available. The reason of this, in our opinion, is explained by the fact that the relations of stations are not connected with final results of agricultural production. The efficiency of their functioning will become economically viable only when their own profitable activities ensure the effectiveness of services for agricultural producers. The purpose of the research is to justify the need of creation machine-technological stations in the system of agroindustrial production.

Published: April 2020

Abstract
Renewable resources are of particular importance in decentralized power systems typical of the Arctic and remote areas of a number of countries. One of the fastest growing renewable energy sources is kinetic wind energy used for power generation. Over the past two decades alone, the installed capacity of wind turbines in the European Union has increased hundreds of times, with a significant reduction in the cost of generation. The article discusses some aspects and features of wind power development in Northern and remote areas. In some areas of the Arctic coastal and remote areas, the wind speed has a fairly large value; on the one hand, it is considered highly favourable conditions for the economically efficient use of wind energy. On the other hand, wind speed exceeding certain limits can cause significant loads to be placed on wind turbines components and parts, resulting in the destruction of the device as a whole. The article discusses the possibilities of improving the reliability and durability of wind turbines operating under extreme loads. In addition, as a rule, wind farms are used where the wind speed is characterized by appropriate values, in places with low terrain and a shortage of natural resources. On the basis of methods of multidimensional scaling, cluster analysis, fuzzy modelling, the article investigates the possibilities for determining the most suitable, from the point of view of economic efficiency, places for installation of wind farms with optimization of schemes of their joint application. The technique of determining the wind characteristics and taking into account these characteristics to identify regions with the most favourable conditions for the use of wind turbines and the development of wind power in general are shown.

Abstract
The work is devoted to the analysis of the regional industry level development in the Orenburg region. The state of the oil and gas industry, power industry, metallurgy, mechanical engineering and light industry has been considered. The analysis showed that since 2012, the region is characterized by multidirectional dynamics of the sectoral structure industry, in the face of fluctuations — either growth or production decline in individual sectors. There are positive moments. Orenburg region has successfully implemented its solar potential over the past 5 years. During this period, the region has earned 7 solar power plants with a total capacity of 200 MW. Further, the paper proposes a method for multidimensional assessment of the industry state. It consists in building a beam of coordinated development of industries and determining in the plane called theequal contributions plane of two parameters: distance and angle of rotation. The distance is estimated as the distance between the point representing the given moment and the point of intersection of the beam of coordinated development with the plane of equal contributions. The angle of rotation is determined between the line of intersection of the constant plane on the main type of production (oil production) with the plane of equal contributions and the line passing through the point of intersection of the beam of coordinated development with the plane of equal contributions and representing the point
Innovative Development of Mechanical Engineering Complex Based on Project Management

Published: April 2020

Abstract
The relevance of the study is driven by peculiar features of the current economic model characterized as rapidly changing and requiring maximum flexibility from all market agents. In this situation such factors as scientific, technological, innovative, informational development come to the fore. Accordingly, it is necessary to choose adequate methods for the management of key industries, which include mechanical engineering. In our opinion, for the purposes of mechanical engineering further development it is necessary to develop a strategy for the scientific and technological development of the entire complex aimed at modernizing the material and technical base, organization, technology, socio–environmental sector, personnel and information support of production, increasing the investment attractiveness of mechanical engineering and expanding the markets for domestic products sale. To overcome the crisis, the main strategic objective of the Russian government should be to recover and ensure intensive growth of domestic markets for industrial products consumption. This is only possible with the implementation of many large infrastructure projects that will ensure domestic demand. Project management, which gradually replaced traditional management, is based on the preliminary development of a comprehensive system model in order to achieve the original goal and is aimed at implementing this model within the specific time frames. It is important to keep in mind that the objective in project management is usually distinguished by elements of novelty and, therefore, the project itself is original, non–traditional. The concept of project portfolio management should be defined separately. Project portfolio management helps determine the optimal level of investment for each project, which should be well combined with each other and not contradict the overall strategic plan. The result is the best balance between current and new strategic initiatives. At the same time project portfolio management is a tool for achieving strategic goals (including industry goals).
Biological Aspects of Economic Efficiency of Crop Farming
Authors: Glinushkin A P , Startsev V I , Startseva L V 
Published: April 2020

Abstract
A robust increase in crop production has lately been associated with the government incentives to agricultural producers to comply with production technologies, which include the use of synthetic fertilizers in the required quantities. Heavy crop yields remove nutrients from the soil, thus, necessitating supplementary fertilizing, which affects the soil, it being a developed agricultural ecosystem. The plant nutrient uptake from the soil becomes difficult, phytotoxic effect may occur. Certain measures for soil rehabilitation should then be taken, the most important of which is the use of green manure and minor nutrients as a basis of the symbiotic relationship between organic and mineral constituents of the soil.
Innovations as a Factor for the Sustainable Functioning of a Construction Company
Authors: Shreyber A , Abramov I 
Published: April 2020

Abstract
Competitive threats from international and domestic construction companies compel construction industry participants to intensify innovative processes with a view to improving the profitability of construction operations, expanding their offerings and upgrading the quality of their products.
The introduction of assorted innovations is thus a way of enhancing the efficiency of construction operations.
In terms of development levels, innovations may be classified into global, national, regional and industrywide.
A construction company can introduce innovations by:
- Consuming or using materials, machinery or equipment;
- Making construction products in the form of units, buildings or structures;
- Applying products to control corporate organizational structures and construction operations. Focused on technological innovations, this paper identifies those in the heaviest demand, used most frequently in construction operations, exploring the impacts of construction operation innovations on the sustainable functioning of a construction company. The authors propose a research and engineering hypothesis to the effect that the expert assessment method is instrumental in identifying innovations with positive impacts on construction operations, while ensuring the sustainable functioning of a construction company, subject to the correct selection of experts and assessment criteria.
Peculiarities of Steam Treatment of Food Plant Products and Simulation Thereof

Published: April 2020

Abstract
Methods of water steam treatment of disperse food raw materials at various pressures have become widely used in the processing industry. Humidity and temperature conditioning, drying and blanching are typical non-stationary processes progressing at a uniform or non-uniform (decreasing) rate. This article describes an analytical solution to the system of differential equations of joint heat and mass transfer outlining distribution of heat and moisture fields at the material heating stage. The following peculiarities of the food raw materials processing have been considered to set the appropriate boundary value problem: some of the processed food quality horticultural products (harvested potatoes to be dried, washed fruits or pretreated sunflower seeds prior to vegetable oil expression) were included with the group of products characterized by a tight-fitting subspherical fruit (seed) coat, which is why we consider them a single, homogenous, and isotropic particle with averaged thermophysical properties. The difference in temperatures of the heated air and the treated material results in condensation and formation of a liquid film on the surface of the objects, which is why heat is spontaneously transferred from the condensate film to the body primarily on account of heat conductivity and moisture distribution from the periphery to the center. The issues of storing agricultural plant products closely related to the discussed ones are no less important. Rational natural resource management globally acknowledged as the dominant economic development trend presumes the fullest possible use of processed human-consumed plant products. For instance, vegetable proteins prevail over meat ones in food patterns in most countries. In Japan, this ratio is 78.3/21.7, in Ukraine - 72.3/27.7, in the USA - 65.3/32.9, in the United Kingdom - 61.?/32.4, in Germany - 65.3/34.7, in France - 60/40, in Canada - 68.4/31.6, in China - 87.3/12.7, in Italy - 74.6/25.4. Adequate storage of the harvested plant products prepared for processing significantly contributes to the solution of this problem. Given the considerable amount of root vegetables, grain and seeds in food plant products, it is clear why foodstuff manufacturers show interest to conditions and modes of storage thereof. Modern warehouses used for these purposes are equipped with various means to ensure required hygrothermal modes and even to control composition of the environment within the units intended to store preserved bulk root vegetables, grain and seeds. That is why the discussed problems of analytical evaluation of storage conditions for various steam-treated bulk agricultural raw materials are of genuine interest.

Abstract
Use of porous materials in heat exchangers makes them more efficient in a smaller form-factor. Heat exchangers based on porous materials have uses in various industries, e.g. in power engineering. The latter currently relies on steam-to-water heat exchangers that load the environment. One promising way to make heat exchangers more eco-friendly is to use porous materials. An experimental setup was made to study heat transfer in porous materials. The setup enabled the research team to find the degree of cooling the hot coolant (water) passing through a porous heat exchanger. For comparison, experiments also involved a second heat exchanger (tubular, non-porous). The paper presents the installation diagram and the experiment methodology. It also reports the processed experimental data, draws conclusions, and suggests further experimentation.

Published: April 2020

Abstract
The use of multilayer enclosing structures in modern construction poses a new task of studying the mutual influence of all materials of multilayer structures on the durability of the structure as a whole. Masonry is the oldest and most representative multi-component envelopes. This work is devoted to the study of the processes of chemical destruction, taking into account the mutual influence of building ceramics (clay bricks) and cement-sand mortar. The article deals with the main process of destruction of materials, based on the destruction of the amorphous part of the brick under the influence of calcium hydroxide, penetrating into the brick of cement-sand mortar, where it is produced in the process of dehydration of calcium silicates and aluminosilicates (leaching reaction). We consider the side processes of the first type, taking into account the presence in the amorphous phase of brick oxides of alkali and alkali-earth metals.
