The Theory of Agriculture Multifunctionality on the Example of Private Households

Having appeared in the European Union, the multifunctionality theory was quickly appreciated in most countries of the world. It determines the role of agriculture and its structural elements in the modern economy. This article is aimed at studying the multifunctionality theory in Russia. This study was conducted on the example of private farms in the Samara region by the authors’ classification and identifying their main functions can serve as the basis for a system of their state support. To process the study results, absolute, relative, and average values were used, as well as a regression analysis with the help of the STATISTICA package. The research results are presented in tabular and graphical forms. The growth of production volumes does not lead to an increase in the share of households according to total volume in the case of a steady trend. The impact of all factors on the indicator, except for the production volume amount, results in a 2.272% decrease in the proportion of household plots in the total volume of agricultural regional production annually. It was found that the parameters of households depend mainly not on the geographical location within the region but on the size of the settlements in which they are located. The research result shows that the main focus of state regulation for private farms should be aimed at their support in small settlements, thus ensuring a quick return on invested budget funds. The outcome of the multifunctionality theory in practice should be the strengthening of state support for private farms.

Geomorphological Classification of Monogenetic Volcanoes and Its Implication to Tectonic Stress Orientation in the Middle Atlas Volcanic Field (Morocco)

The Middle Atlas Volcanic Field (MAVF) covers an area of 1500 km2, with a total erupted volume of solid products (e.g., Dense Rock Equivalent or DRE) estimated to be more than 80 km3. The MAVF comprises 87 monogenetic basaltic volcanoes of Tertiary-Quaternary age as scoria cones (71%) and maars (29%). These monogenetic basaltic volcanoes have various morphologies (e.g., circular, semi-elliptic, elliptic in map views). They can be isolated or form clustered monogenetic complexes. They are largely grouped in the Middle Atlas, in an intraplate geotectonic context forming two distinct major alignments (N160–170° and N40–50°), each closely associated with regional structural elements. By the best estimates, the preserved bulk pyroclastic products do not exceed 0.7 km3, and they show large textural and componentry diversity (e.g., bedded/unbedded, coarse/fine, dense/scoriaceous fallout and pyroclastic density current deposit, etc.). Lava flows also demonstrate great variety of preserved surface textures, including pāhoehoe, ‘a’ā, and clastogenic types. Morphostructural features of lava flows linked to lava flow dynamics have also been recognized, and the presence of hornitos, columnar jointed basaltic flow units, lava tubes, tumuli, and clastogenic lava flows have been recognized and mapped. Some half-sectioned dykes expose interior parts of magmatic shallow feeding pipes. The current morphology of the volcanoes of the MAVF reflects various syn- and post-eruptive processes, including (1) erosional features due to weathering, (2) gravitational instability during and after volcanic activity, (3) vegetation impact, and (4) successive burial of lava flows. The documented volcanic features of this typical monogenetic volcanic field form the core of the region’s geoheritage elements and are considered to be unique in the new African geoheritage context. Hence, they will likely form the basis of future geotourism, geoeducation, and geoconservation ventures.

Increasing the content of coarse fractions in the mined coal mass by a combine using paired cuts

The main volume of coal is mined underground using shearers. In modern shearers, auger actuators are mainly used, which are distinguished by the simplicity of design, manufacturability and reliability. However, in the process of separating coal from mass by cutting, the yield of fine grades is 40-50 % of the total production volume. Therefore, the search and development of technical solutions that provide an increase in the yield of large fractions in the process of coal mining with auger shearers is an urgent task. Traditionally, this problem is solved by increasing the thickness of the slices, which is achieved by installing cutters with a larger radial reach and increasing the shearer feed rate. An unconventional way to increase the cross section of slices by forming energy-efficient paired and group slices with mutual superposition of stress fields in the mass from the action of neighboring cutters is considered. The results of modeling the process of cutting coal confirm that an increase in the efficiency of destruction of the rock mass by the cutters of the auger executive bodies of the shearer can be achieved by a complex technical solution, including the formation of paired cuts and combined stress zones in the rock mass. As a result, the output of large fragments when cutting with paired cutters increases by 1.3-1.8 times compared with cutting with a single cutter.

Characterization of supply of marine finfish species with potential for commercial growth in the United States

AbstractGlobal production of marine finfish has grown in total volume of production and the number of species farmed commercially, but there has been little production in the United States of marine finfish other than salmon and red drum. For most species considered to be ready for commercialization, there are few or no farms from which to evaluate the size of the market or to estimate revenues and costs necessary to assess economic feasibility. This present study takes a first step to fill this gap with an analysis of the existing supply of 20 marine finfish species identified as candidates for commercialization in the United States, as a proxy for effective demand (the volume of a product sold at the market equilibrium price). Secondary data from 1950 (where available) through 2019 were compiled on each species, including (1) global aquaculture production, (2) US aquaculture production, (3) US commercial landings, (4) US recreational landings, and (5) imports. Current effective market demand (measured as the sum of commercial landings, farmed production, and imports) was low, totaling 36.6 million kg across the 20 species, which is equivalent to less than 23% of the annual volume sold of US farmed catfish. Commercial landings for 17 of the 20 species exhibited declines, potentially offering opportunities for farmed product to capture market share by filling the increasing gaps in supply. The variability in commercial landings provides opportunities for farms to capitalize on their advantage in supplying product with a high degree of consistency of volume, size, delivery frequency, and quality. Several unknown factors suggest the need for follow‐up studies on consumer preferences, degree of substitutability among finfish species, and effects of recreational landings on demand. An important limitation to prospective producers is the lack of species‐specific import data for the generic categories of “flounder,” “bass,” and “snapper.” This supply analysis provides a foundational analysis for prospective producers, investors, and researchers interested in commercialization of these marine species.

Operational management of the bus fleet maintenance and repair system

Introduction. Recently, due to the increase in the number of vehicles, including public transport, there is a need to streamline the system of maintenance and repair, taking into account the mass of incoming applications for these operations. A decrease in productivity may occur due to an unclear distribution of work by performers, inconsistency of their actions in time and irrational use of technological equipment. The purpose of the research is to develop a system for organizing maintenance and repair of rolling stock based on the principles of centralization and cooperation with other production structures. To achieve this goal, statistical methods, methods of the theory of random processes and queuing theory are used. The concentration of production occurs either due to the growth of the share of large enterprises in the total volume of production of the region / industry (transportation of passengers of the metropolis) or due to the growth of the size of the manufacturing enterprises themselves. The process of concentration can be argued from the standpoint of the principles of synergetics.Materials and methods. The article discusses the operational management of the system of maintenance and repair of the bus fleet. The division of tasks of the technical service of a motor transport enterprise into four complexes is presented. Two ways of drawing up a schedule are analyzed: calendar and by actual mileage of cars. The analysis revealed the advantages and disadvantages of each of the options. The advantages and disadvantages of universal and specialized posts are analyzed, indicating ways to eliminate the identified shortcomings. The positive effect of centralization of management of the specified complexes of tasks for maintenance and repair of rolling stock is substantiated.Results. A scheme for servicing applications for routine repairs with decentralized and centralized systems for managing the production of routine repairs of rolling stock is proposed. The basic principles of functioning of a centralized production management system are described. A general structural scheme of centralized specialized production is proposed. The structural composition of the pre-production complex is presented, with a description of each unit included in its system: a complete set group, an intermediate warehouse, a transport section, a washing and defect section, a tool section. The tasks of the operational management department and the information processing and analysis department, which are part of the control center of a centralized specialized production, are outlined.Discussion and conclusions. The results of the study are intended for the enterprises of passenger transport. This study is an integral part of the development of a common system of centralization and cooperation of maintenance of rolling stock.

Transition from traditional energy to renewable energy: assessment of the contribution of renewable energy in greenhouse gas emissions reduction on the example of the Yereimentau wind farm

Kazakhstan has a high potential for creating international-class green energy, but at the moment alternative energy resources are used in a small amount due to various technical, administrative, social and economic obstacles. This work is devoted to the analysis of the share of renewable energy generated in the total volume of electricity production in Kazakhstan, the amount of electricity produced by renewable energy facilities is estimated. Also in this paper, an assessment of greenhouse gas emissions reductions was carried out on the example of the largest wind power plant in Kazakhstan with a capacity of 45 MW in the city of Yerementau. The share of renewable energy sources in the country’s energy balance was estimated by comparison. The annual data on the generation of electric energy by renewable energy facilities for 2016-2021 are compared according to the statistical data of the Republic of Kazakhstan. A methodological approach to the calculation of greenhouse gas emissions reductions based on a baseline scenario is proposed, which can be used as a methodology for calculating greenhouse gas emissions reductions at renewable energy facilities. Assessment of reductions in greenhouse gas emissions as a result of the implementation of renewable energy projects is important both for calculating the national carbon balance of the country as a whole and for accurately calculating the units of reductions planned to be issued as a result of the implementation of these projects. The Yerementau wind power plant will help the Republic of Kazakhstan in achieving the goals set ahead – increasing the share of renewable energy sources and reducing carbon dioxide emissions. Key words: renewable energy sources (RES), emission reduction, wind power, greenhouse gases, emission factor.

Assessment of the current state of the domestic mixed fodder market under the new economic reality

The article reveals the current state of the domestic market of the feed industry of the Russian Federation, provides data on production volumes and pricing policy in the field of feed and premixes. The main problems associated with ensuring the stable development of the feed industry in the conditions of global instability are outlined. The production volumes of the industry are increasing every year. According to Rosstat, in 2021, the volume of feed production in Russia amounted to 31.9 million tons, which is about 1.1 million tons, or 3.4%, more than a year earlier. At the same time, in the overall structure of production, the share of compound feed for poultry accounted for 49.0% of the total production volume (15,719.6 thousand tons), the share of compound feed for pigs and cattle, respectively, 41.9% (13,421.3 thousand . t) and 8.4% (2,680.3 thousand tons), for other animals - 0.7% (239.5 thousand tons). There are practically no strategic stocks of feed additives in the country, but grain stocks are still stable. The main difficulties that the feed industry is already facing are the statuses of importers of feed additives that are not fully understood. The study made it possible to form a general idea of the current state and development trends of domestic feed production and its raw materials. Not only the stable and progressive future of the domestic feed industry, but also the provision of the country's food security depends on the quality and efficiency of making managerial decisions on these problems.

Evaluation of the Effectiveness and Adaptability of a Composite Water Control Process for Horizontal Wells in Deepwater Gas Reservoirs

Deepwater gas fields have high bottom water energy and a high risk of seeing water. Higher requirements are put forward for the water control process to control the water effect. This article is based on the actual background and well design of the X gas field in the South China Sea and on three sets of physical simulation experiments and three sets of numerical simulation experiments. An analysis and comparison of the water control effect of a combination of continuous packer, continuous packer and variable density screen tube, and their adaptability evaluation in deepwater gas reservoirs were performed. The results obtained from the numerical and physical simulations are consistent. The experimental results show that the water control process of a continuous packer is mainly based on the water-seeing and water-blocking ability. It is less capable of extending the time to produce water in the horizontal section. However, its water-blocking ability is strong and is able to seal the water spot quickly. It extends the total production time by 12.29% and increases the total gas production by 5.96%; the combined water control process of the continuous packer and variable density screen tube can effectively play their respective advantages of water control. The combination of the continuous packer and variable density screen tube can effectively be advantageous of their respective water control processes, enabling the gas–water interface to advance in a balanced manner, extending the water-free gas recovery period by 11.61%, extending the total gas production time by 15.76%, and increasing the total gas production volume by 13.75%. Both water control processes have good applicability in deepwater gas fields and have certain sand control capability. It is conducive to the one-time completion operation for the commissioning of deepwater gas fields.

Modeling of production indicators of mining companies to improve the efficiency of the management system

In the context of the special relevance of the oil and gas complex for Russia, many new oil and gas fields are being developed and exploited every year. The state, in an effort to stimulate economic growth, implements large-scale projects related to the extraction of hydrocarbons. Such projects require geological and economic assessment, which can take place both at different stages of development and by different methods. In this paper, a general method of forecasting total production volumes, drive through mathematical induction, is presented. The methods of forecasting production volumes by the average debit, as well as by the initial and current debit are mathematically described. And also a proof of the hypothesis using mathematical induction is presented. This work can be useful for modeling forecasting by mathematical and economic methods of production indicators of an oil field.

The Impact of Germinated Chickpea Flour Addition on Dough Rheology and Bread Quality.

The research focused on the effect of germinated chickpea flour (GCF) in a lyophilized form on dough rheology, microstructure and bread quality. The GCF addition levels in refined wheat flour with a low α-amylase activity were 5%, 10%, 15% and 20%, up to an optimum falling number value of the mixed flour. Generally, the dough rheological properties of water absorption, tolerance to mixing, dough consistency, dough extensibility, index of swelling, baking strength and loss tangent (tan δ) for the temperature sweep test decreased with the increased level of GCF addition, whereas the total volume of gas production and G′ and G″ modules for the temperature sweep test increased. Dough microstructure analyzed by epifluorescence light microscopy (EFLM) clearly showed a change in the starch and gluten distribution from the dough system by an increase in protein and a decrease in starch granules phase with the increased level of GCF addition in wheat flour. The bread physical characteristics (loaf volume, porosity, elasticity) and sensory ones were improved with up to 15% GCF addition in wheat flour. The bread firmness increased, whereas the bread gumminess, cohesiveness and resilience decreased with increased GCF addition in wheat flour. The bread crust and crumb color of the bread samples become darker with an increased GCF addition in the bread recipe.

The scientific article is devoted to the analysis of approaches to the development of cluster formations in different countries. Researchers distinguish three main models of cluster creation based on the economic and geographical approach and the development of certain megaregions: the American, Western European and Asian models. However, this approach is not universal, since it does not take into account the different availability of Natural Resources, the capacity of national and regional markets, the role of the state in regulating the economy, the specifics of industry, and so on. A research aim is to analyze economic and geographical approaches to the development of cluster formations in different countries. The subject of the research is mechanisms for ensuring clustering of economic elements. For the aim of the research, the following methods were used: comparative, statistical, descriptive, system analysis and synthesis. The basic hypothesis of research was the analysis of the components of the formation of a cluster structure: the innovation component and the competitiveness model, which will reveal the main features and limitations of the clustering process. Exposition of basic material. The article considers the study of economic and geographical approaches to clustering based on the innovative component and key elements of the economic competitiveness model: Natural Resources, macro-and microeconomic competitiveness. The article considers the cluster specialization of countries according to industry affiliation, and provides a statistical analysis of the structure of production of finished products by enterprises that are part of cluster formations in the total volume of production. Originality and practical meaningfulness of research is due to the analysis of the structural components of cluster formations, taking into account regional features. Conclusions and prospects for further research. The analysis of economic and geographical approaches to the development of cluster formations in different countries has shown that enterprises that are part of cluster formations introduce innovations faster and more efficiently, the production process is better established, collaboration and cooperation relations are formed between the participants of the cluster system. However, due to the differences in resource, competitive innovation, economic, and regulatory legal components, the process of studying the system of cluster formations needs to be continued.

Global Trade Pattern of Traditional Chinese Medicines and China's Trade Position.

To depict the evolution of the global trade of traditional Chinese medicine (TCM) products, this article analyzes the 2001–2020 trade data of TCM products in the World Bank and United Nations Commodity Trade Statistics Database to discern the spatial-temporal evolution characteristics of global and China's trade patterns of TCM products from 2001 to 2020 and thereby assess the changes in the global trade of TCM products and in the positions of various countries or regions in the global trade of TCM products. Research findings are as follows: First, on the whole, the total trade volume of TCM products and the number of participating economies and trade connections are on the rise. Second, in terms of topological structure, with higher network density and rising transmission efficiency, the global trade network of TCM products has typical small-world and scale-free network characteristics and has begun to be controlled by a few countries. Judging from the co-opetition between major trading countries, there are more diversified sources of imports for major trading countries, and there is competition between supplying countries. Third, For China, the trade volume of TCM products between China and various countries worldwide has grown rapidly and exhibits a trend of continuous increase followed by decline. China has established extensive trade partnerships and its position in the global trade network of TCM products has been continuously improved. China's participation has contributed to a closer connection among trading entities, but its network heterogeneity remains to be further improved. From the perspective of trade interdependence, the number of countries or regions maintaining high interdependence with China has been gradually increasing, and most of them are European and American countries, Japan, and Southeast Asian countries. The number of countries or regions maintaining low interdependence with China has gradually decreased, and countries or regions that are completely one-way dependent on China are nonexistent.

АНАЛИЗ И ТЕНДЕНЦИИ РАЗВИТИЯ СЕЛЬСКОГО ХОЗЯЙСТВА В УСЛОВИЯХ ЦИФРОВИЗАЦИИ

In the course of agrarian transformations in agriculture in recent decades, there have been profound social and economic changes in the framework of agrarian reform. There has been a trend of transition to new innovative realities in the form of digital transformation of agribusiness, which served as the main goal of the study in the form of analyzing the readiness of agricultural sectors for technical and technological modernization of production and identifying barriers to digitalization of agribusiness. Using generally accepted empirical research methods in the form of a comparison of agribusiness indicators over a number of years, an ambiguous trend in the development of the main production indicators was revealed. From 2011 to 2020 the share of crop production in the Russian Federation in the total volume of agricultural production increased from 50.56% to 53.63%, while the share of animal husbandry decreased by 3.07 percentage points and amounted to 46.37% by 2020. This trend could be a good basis for the introduction of digital technologies. The survey made it possible to cover a large number of respondents and identify a number of problems facing farmers in the transition to a digital economy. Among them: the lack of state support, the high cost of digital products, the lack of awareness of digital innovations, the underdevelopment of infrastructure, the lack of high-tech equipment and personnel with digital competencies. Based on the identified factors hindering the development of digital transformation, the authors propose the main instruments of state and market regulation of the digital transformation of agriculture, which can become the basis for solving a number of problems that have arisen

Analysis of factors of increasing innovation activity of domestic enterprises

Current trends show that the most relevant direction of maintaining competitiveness and obtaining competitive advantages of any state is the development of innovative technologies and knowledge-intensive industries. In this regard, the Russian government faces the task of forming a comprehensive innovation system based on its own technological developments. The fundamental factor contributing to the more effective development of such a system is the innovative activity of enterprises. It is necessary to consider it, as well as factors affecting its condition. It is also worth noting the uneven innovation activity characteristic of our country in different regions, depending mainly on the availability and development of key factors, such as economic infrastructure, financing, scale of production, etc. To date, the share of innovative products produced by theRussian Federation in the total volume of industrial production is approximately 6.7 %. The same indicator in developed countries is about 1619 %. Another characteristic feature of the Russian economy is the predominance of imports of innovative technologies over their exports. Large and medium-sized industrial enterprises have thegreatest innovation activity, and 60 % of their products are science-intensive.

Оценка конкурентоспособности экономик стран ЕАЭС

The article presents the results of a study of competitiveness as a factor in the development of the EAEU member states since the creation of the integration association in 2015 and 2020. The study is based on data from EAEU statistics. The article assesses the competitiveness of the economies of the EAEU countries on the basis of indicators of foreign and mutual trade, the share of the manufacturing industry in the total volume of industrial production, as well as labor productivity. According to the results of the analysis, the countries were identified - those that receive a greater effect from participation in the integration union, and those who are more focused on trade with third countries. Using the author's methodology, an assessment of the competitiveness of industry was carried out and an index of export similarity was calculated in comparison with the European Union. The results showed that the complementarity of economies within the EAEU is still low, and therefore the contribution of integration processes to the development of the economy is still insignificant. The main reasons for the current state of affairs, in addition to the factor of low complementarity of the structure of the economies of the EAEU countries, are that the advantages associated with the creation of the EAEU require the implementation of national economic policy measures related to supporting promising areas of cross-border interregional cooperation.

Biogas manufacture from co-digestion of untreated primary sludge with raw chicken manure under anaerobic mesophilic environmental conditions

This work aimed to co-digest various wastes to assess the best combination of all mixing ratio, also at choosing the best ratio between untreated primary sludge (UPS) singly from two sources, (South valley University (SUPS) and Abu tesht wastewater station (AUPS) and raw chicken manure (RCM) and comparing the results in either case. The co-digestions of untreated primary sludge from Abu tesht wastewater treatment stations with different levels of raw chicken manure (0:100, 10:90, 30:70, 50:50, 90:10, and 100:0) to obtain the best mixtures. Also, co-digestion of untreated primary sludge from south valley university with different levels of raw chicken manure at the same ratios, to obtain the best mixtures. Batch digestion tests were applied in 2.5 L digester with a working volume of 2.0 L. The samples in triplicates were separately loaded into the digesters locally fabricated and kept for 20 days as a retention period and diluted with the same amount of water. Mesophilic under 35 °C was adopted for untreated primary sludge as well as mixtures with raw chicken manure based on total solids (TS) and volatile solid (VS) proportions. The average biogas yields from AUPS/RCM mixture obtained ranged from 8570 to 5600 ml, by the following descending order, 10: 90 > 90:10 and so on >100:0, and the average biogas yields from SUPS/RCM obtained ranged from 6330 to 5635 ml, in the order of 90: 10 > 10:90 and so on >100:0. The results showed highest biogas yield from AUPS/RCM and SUPS/RCM mixtures with mixing ratio of 10:90 and 90:10, respectively, however, the lowest biogas production detected in separate digestion of AUPS and SUPS. The results indicated that co-digestion between the sludge and raw chicken manure could increase total biogas production volume, enhance sludge treatment process, and produce eco-friendly sludge because of co-digestion process than separate processing of each feedstock.

Study of innovation activity dynamics in Russia’s federal districts

The dynamics of indicators of innovation activities of Russia’s federal districts over 2005– 2019 has been studied. During this period, there has been an increase in the number of organisations that carried out research activities, and also in the total domestic expenditure on research and development. The number of new production technologies and the volume of innovative products produced has increased, and the payback rate on research and development costs has risen in all regions. The trends of decreasing in the innovation activities of organisations and a significant reduction in the number of personnel employed in the field of research and development have been detected. The share of new products in the total volume of products shipped remains low. This situation requires national and regional authorities to take appropriate regulatory actions.

Value of grain-growing sector within agro-industrial production: Structural changes and development trends

During the 20th and first quarter of the 21st century, there have been not only significant quantitative, but also structural changes in grain production close to some central applications of grain: food consumption, fodder consumption, industrial consumption, provision of seed production, foreign trade. Strategic planning of grain production in the country depends on many factors, including changes in grain production and processing technologies, widespread and accelerated integration of selective breeding results, multifactorial modeling of animal diets. The volume of consumption and the structure of cereals in the total volume of production is impacted by such processes as population growth, urbanization and changes in dietary preferences of modern people. One of the most important tasks in the development of the farming industry is to assess some possible prospects for the development of grain growing, with due account for new priorities to come up in the use of the entire biodiversity of cereals. Benchmark analysis of the ratio between the volumes of production, consumption and export-import of grain, rationale for the optimal characteristics of the grain-growing sector of the national economy, as an essential element of strategic potential, represent one of the fundamental interdisciplinary challenges facing modern science.

Моделирование и оптимальная диспетчеризация процессов в производственно-логистических комплексах

The paper regards the problem of maximizing the total volume of homogeneous products delivered from the point of production to the distribution center, in the presence of a significant number of practical restrictions on the schemes of technological cycles. Considered issue allows assessing the consequences of economic downturns, caused by the spread of infections. For this task, formalization is constructed in the form of a binary linear programming problem based on discretization of the planning horizon. The adequacy of the proposed formalization is illustrated by a test example of relatively small dimension. The main approaches are described that make it possible both to obtain an exact solution of the considered problem (for special cases) and to construct approximations.
