The development of the agricultural sector and the entire national economy of Russia at the present stage is determined by the key realities of globalization trends and the mechanism of adaptation to them. The current confrontation of the interests of world powers under the influence of sanctions against Russia, which is a new form of global political and economic transformation, requires increased use of tools and mechanisms for state regulation of socio-economic processes, the main of which is strategic planning. The system of state planning has always been and remains the most important tool for justifying agricultural policy, both at the Federal and regional levels, which determines the search for the main trajectory of economic development of agricultural production sectors. The article deals with the deep causes of the protracted systemic crisis in the agricultural sector of the country’s economy. It is revealed that the lack of effective science-based tools of the state management system is becoming the main factor hindering the development of the country’s agricultural production sector. It is established that in the new Russian reality, state management of the agricultural sector of the economy should be based on its key function – strategic planning. The necessity of implementing a systematic campaign in planning is justified. Methodological aspects of the development and implementation of program-target planning in agriculture in Russia allowed us to identify the main shortcomings of the modern practice of planning and forecasting. The necessity of developing a strategy for the development of agriculture in the new macroeconomic conditions is justified. The developed model of a modern strategic planning system based on an integrated approach, including concepts, forecasts, economic orientation, plans, programs, excludes the possibility of fragmented planning and forecast management of the agricultural sector of the economy.

Published: October 2020

The development of the marine industry and processing of raw materials is very important. Many floating marine transport platforms are engaged in processing and preparing raw materials. The paper presents an experimental study of the absorption method of the dependence of the degree of protein denaturation on the absolute value of external hydrostatic pressure, which was used to process minced fish for 5 minutes at a temperature of 295 K. A mathematical model of the process of denaturation of protein molecules in minced fish under the influence of high hydrostatic pressure has been developed. Based on experimental data, the equilibrium constant K = 0.0019439869 of denaturation of protein molecules after 5-minutes action of external hydrostatic pressure at room temperature was determined. Extrapolation of experimental data using a model curve determined the pressure P = 520 MPa, at which the concentration of denatured protein molecules in minced fish for 5 minutes at a temperature of 295 K becomes equal to the concentration of denatured protein molecules in boiled minced fish. These studies are very important for the food and transport industry.

Published: October 2020

The paper is devoted to the formation of a system of reliability indicators for joints and rail crossings. Reliability indices related to the groups: reliability, durability, maintainability, safety, are considered. Since the joints and crossings of rail tracks consist of a system of elements, a model of functioning, in particular turnout, is built for their analysis. As a comprehensive indicator of reliability, it is advisable to use the availability factor - the probability that the object will be in working condition at an arbitrary time moment, except for periods of scheduled maintenance, and will work without fail during the periods between scheduled maintenance works. The basis of the methodology for determining the readiness coefficient of the turnout economy of an infrastructure object can be the concept of a reference turnout. As a reference turnout, it is advisable to take the most widespread type of turnout products used on the railroads of a particular infrastructure owner. Reliability indices of specific types of turnout products operated at specific places of track development of stations can be determined using a system of coefficients that take into account the design features of this turnout and the conditions of its operation. The greater the availability factor, the more reliable the transportation process is.

Authors: Yurieva N I , Vitvitskiy E E
Published: October 2020

Solving operational tasks in the planning of road freight transportation requires the transportation organizer to take into account the possible impact of a set of factors on the performance of vehicles: the volume of transportation, transport work performed at the specified time, transportation costs, and the cost of the transportation contract. Modern theoretical and methodological provisions in the field of operational planning of road freight transportation are the basis for the development of a more correct theoretical and practical base for the cost of road transportation. The previously established theoretical dependencies of the impact of technical and operational indicators on the effectiveness of road transport systems of cargo transportation (RTSCT) and the operation of rolling stock do not take into account the specifics of the organizational and legal forms (OLF) of Carriers. The practice of cargo functioning of road transport systems, but also on the complex of organizational factors of the functioning of Carriers. Studies and calculations of possible results of one car on the pendulum route with a return unloaded mileage during the time spent in the duty were carried out using the example of transporting sand by car-dump truck in the city of Omsk, as part of a Carriers with different OLF with the number of cars in the composition of up to 20 units.

Published: October 2020

Improving the quality of human capital in transport is closely related to the development of the ability of transport specialists to self-regulation. The training of modern, qualified transport specialists (as human capital development strategy) requires no less highly qualified teachers and managers, capable of not only managing others, but also themselves. In modern socio-cultural space, researchers pay special attention to the preservation and development of man as the highest value, the recognition and upholding of him as the highest value on earth. Such an understanding assumes the professionalism of consultative interaction with the client as a person, partner and professional, based on a detailed analysis of the characteristics and properties, processes and results of human activities. Appeal to followers in understanding the human mental life is associated with well-known methods for diagnosing and transforming the most complex internal world of a person, as well as the features, processes and results of the interaction of the internal and external worlds surrounding a person. Psychological comprehension of a person, penetration into the matrix structures of his personal, interpersonal and professional formation and development is sometimes serious difficulties, so our appeal to the psychodynamic and behavioural models of self-regulation, as well as in social and individual psychology and their methods, is dictated by these ideas. The appeal to classical conceptual constructs, in particular, modern and traditional domestic and foreign psychology, allows us to comprehend and practically develop methods and methods of immersion in the mental world of a person, his research, as well as subsequent transformation and development.

Authors: Kivarina Mariya , Makarevich Anna
Published: October 2020

The development of the services market is impossible without improving the regulation of trade in services. Trade in services has been regulated bilaterally for many years. However, as a result of the emergence of a network of services based on the use of modern technical means of communication and computers, the effectiveness of traditional regulatory methods in this area has decreased, which, in turn, has hindered the full realization of the economic potential of scientific and technological progress in the service sector. As a result, it became necessary to create a universal effective mechanism by which trade relations in this area could be coord inated. An important component of the implementation of state and private projects in the field of socially significant public interests at an effective level is the study of the functioning environment of economic entities that is adequate to modern competitive conditions for the provision of socially significant services. First, we are talking about the formation of a business environment, the functioning conditions of which are set by the state. The article substantiates the need to form a system of relations between economic entities based on the principles of public-private partnership in the field of public passenger transport services. It is proved that this system is aimed not only at increasing the number of financially independent actors and their associations, but also at transforming state institutions that become active participants in market relations, interacting, and sometimes competing with the business community, transferring more and more functions to it even in those industries for which they previously traditionally held sole responsibility.

Published: October 2020

Occupational injuries rates in the construction industry and transport remain at an unacceptably high level both in Russia and in a number of other countries. According to the world statistics, one of six fatal accidents at work occurs during construction works. Even in industrialized countries, 25% to 40% of all reported fatal accidents occur during construction work, although only 6% to 10% of the total workforce is employed in this industry. The same ratios are peculiar to Russia. According to official statistics, fatal occupational injuries in the country’s construction industry average 20% of the total number of such accidents, although the average number of workers in the construction industry for 2004-2019 does not exceed 7% of all workers. Management measures for occupational safety in construction related to controlling and reducing the risk of injury are not based on any special calculations, quantitative justifications, or application of optimization methods. In the field of inspection arrangement, there are no convincing methods to determine the control program, its results, the level of actual occupational risk, and the necessary time spent on administration of control. The existing causes of accidents in construction are formulated in a generic form, without details, which does not allow indicating specific preventive measures. In this regard, it is important to search for new approaches, methods and means of improving safety, as well as developing preventive measures in the management of occupational safety in the construction industry and transport.

Published: October 2020

Automobile is one of the greatest inventions of mankind which helps people to migrate from one place to another in a short span of time with comfort. In the last few decades, many innovative technologies have been emerging. One such technology is Self Tire Inflation System. This system will monitor the tire pressure continuously and inflates or deflates the tire depending upon the road conditions. But there are many chances for the tire to get blown out, hence the plan of implementing an additional tire-tube setup in the tire has been brought up, which will act as a secondary tube until the primary tube gets blown out. This tube setup makes use of the Self Tire Inflation System and immediately inflates when the primary tire-tube setup gets damaged. This will act as an immediate remedy for reducing the accidents that are caused due to sudden blown out of tire, especially for the Off-Road vehicles and military vehicles that roll their wheels on tough terrain and extreme weather conditions.

Measurement of thermal expansion and contraction of a solid material during heating and cooling is done using dilatometer. To obtain best results dilatometers are operated under vacuum or inert atmosphere. The physical and chemical characteristics are inferred from the dilation of the material. It helps to study the properties of the sintered material and the phase transition of the solid material. Few authors also developed a customized dilatometer for their research applications. This paper deals with those different designs, the various material characteristics providing adequate data to make researchers identify the new area of research for the dissimilar materials. The thermo physical chemical property studies based on the dilatometer are reviewed in this paper.

Present research targets finding compacted quality as well as scraped spot opposition capacity for polymer tar changed cement with silica rage. While exploratory program, solid blends are planned with allotted estimations of water-to-binder proportion at 0.7, volume of total at 67%, sand level at 45% volume of total, as well as polypropylene measure fiber at 0.6 % volume of cement. Trial factors incorporated the silica smolder sum shifted at 0 %, 5% and 10% of powder volume, and the measure of unadulterated acrylic polymer pitch differed at 0%, 5% and 10% load of powder. The exploratory aftereffects of study shows when strength of cement diminished by 22.4 %∼34.2 % with the expansion of the polymer content. The weight decrease of the polymer altered cement incited by scraped area assault diminished 6.78%∼21% and 14.68%∼25.82% in dry and wet conditions, individually.

A novel composite Mg-3Zn-1Cu-0.7Mn reinforced with Al2O3 particulates was synthesized using the powder metallurgy route and extruded at 400°C. The investigation mainly focuses on the influence of Al2O3 on the hardness characteristics of the composites. The results indicate the microhardness of the composite is enormously enhanced by incorporating the Al2O3 particulates to Mg alloy. The homogeneous distribution of the hard ceramic reinforcement particulates and the presence of intermetallic phases such as Cu5Zn8, MgZnCu, and Al0.93Cu1.07Mg attributed the improved hardness. It is recognized that the stress-relieving process further improves the hardness of the composites. The extrusion parameters also influence the hardness characteristics of the composites.

Metal matrix composites (MMCs) corrosion nature is discussed with significance in regard to MMCs corrosion behavior with MMCs electrochemical and chemical properties. Galvanic corrosion between base metal and reinforcement influences the corrosion process in MMCs. The corrosion behaviour of Aluminium Metal Matrix Composites (AMMCs) reinforced with carbide and other solid waste is reviewed. AMMCs are capable of admitting the assault of corrosion over the base metal. AMMC’s corrosion type of behaviour is localized with galvanic corrosion, the intermetallic phase between base alloy and reinforcement, micro cracks, voids, are the corrosion-influencing factors. The corrosive action of solid carbide-reinforced AMMCs (Aluminum Metal Matrix Composites) and other solid waste is analysed. The AMMCs have strong mechanical and tribological characteristics but no achievement in the effects of corrosion. Coatings methods are used to enhance the behaviour of AMMCs in corrosion.

A Rectified Sinusoidal based Pulse generation method for a DC – DC converter is proposed in this discussion. To exhibit this, the methodology is applied to a Self-Lift topology based SEPIC converter. In this paper a two stage grid connected system is used. In stage I the said converter is used for boosting and DC rectification. This converter is considered, can provide the required voltage from a renewable source. The DC rectification is done by using the RSPWM technique. Stage II uses an inverter which inverts the DC rectified signal to produce AC signal. The usage of the bulky transformers are avoided by using the proposed modulation technique. The notable advantages of the RSPWM technique are : (i) the switches of the inverter are functioned at low frequency (50Hz), (ii) harmonic content of the output waveform is reduced because of RSPWM, (iii) decrease of the filter size and (iv) inverter switches life time are increased as complicated control techniques are avoided. These features are validated through simulations.

Biodiesel from plants can compete economically with petroleum diesel fuels as a future prospective fuel. The bio-oil was extracted from the plant of Aloe barbadensis by soxhlet extractor using hexane as an organic solvent, and then further, the oil was analyzed for moisture content, pH, specific gravity, density, viscosity, saponification value, refractive index, peroxide value, acid number, free fatty acid, and iodine value. The results showed that four major fatty acids, like nonadecanoic acid, n-hexadecanoic acid, octadecadienoic acid and octadecenoic acid were present in the bio-oil of Aloe barbadensis and characterized by GC-MS, which showed that the bio-oil could be used for producing high quality of biodiesel. In furture studies, converted crude biooil into biodiesel using hetergenous catalyst will be anlaysed for their engine characteristic studies.
