Materials Used

Problems of technical service of machinery and equipment in animal husbandry are mostly related to the restructuring of the economic model of interaction between agricultural producers and organizations that supply and service of machinery and equipment. Currently, the entrance control of products and spare parts purchased abroad is not established, and the materials used to make parts in contact with milk (teat rubber, milk hoses, etc.) are not checked for compliance with the requirements of the Ministry of Health. (Research purpose) The research purpose is in justifying the structure of the engineering center for integrated solutions in the field of dairy farming based on the Federal Scientific Agroengineering Center VIM. (Materials and methods) The article presents the results of studying sources describing the past and present experience of organizing a system of technical service of machines and equipment for dairy farming in the Russian Federation and foreign countries that are leading in terms of milk production. Authors collected information from key equipment suppliers when visiting industry exhibitions (Euro Tier, AgroFarm, Golden Autumn, etc.). (Results and discussion) The article proposes the concept of creating an engineering center on the basis of the Federal Scientific Agroengineering Center VIM according to the developed structure. (Conclusions) The implementation of the proposed structure for creating an engineering center will eliminate the existing imbalance in the field of technical service of livestock enterprises, establish information, design, machine-technological and service support for the reconstruction and successful development of livestock enterprises in the industry.

Aluminum Oxyhydroxide

Agricultural production in the Russian Federation is several times more energy-and material-intensive than in developed countries. (Research purpose) The research purpose is evaluation of the effectiveness of energy-saving technologies for technical maintenance of equipment using nanostructured aluminum oxyhydroxide and hydrothermal processing of agricultural waste in supercritical conditions. (Materials and methods) Nanostructured aluminum oxyhydroxide (boehmite) was produced by hydrothermal synthesis from aluminum powders. Tribological studies were carried out on a four-ball friction machine, a special device from WAGNER, on friction machines 2070 SMT-1M and MTU. Bench-in run was carried out on the D-240 engine and gearbox of a mobile drilling rig. The crushed solid waste of the agro-industrial complex was used as adsorbents for organic wastewater pollution. Their joint processing was carried out under hydrothermal supercritical conditions. (Results and discussion) It has been shown that nanostructure boehmite has antifriction, antiwear and extreme pressure properties. The possibility of its use as a product for running of a diesel engine has been found. The application of the boehmite in oils accelerates the running-in of a diesel engine, provides savings in material, labor and energy resources. For running-in of power transmission units, an additive containing bemite, surfactant, talc and kaolin reduced the running-in time of the drilling rig gearbox by 2.5 times. The article shows that the crushed plant waste of the agro-industrial complex, such as buckwheat husk, rice, and sunflower can be effectively used as adsorbents for the localization of pollution and wastewater treatment of agricultural enterprises. Subsequent processing of the adsorbent saturated with organic matter under hydrothermal supercritical conditions ensures the complete processing of organic substances to produce purified water and a high-enthalpy vapor-gas mixture or combustible gases, depending on the processing conditions. (Conclusions) Energy-saving technologies for the technical service of a diesel engine and transmission units can be based on the use of tribotechnical materials containing nanostructure boehmite. Technological solutions for energy-saving technologies for processing solid and liquid organic waste can consist in adsorption wastewater treatment followed by hydrothermal treatment in supercritical conditions.

Timely conducting of all types of maintenance and routine repairs is possible only in the conditions of an innovative service center, equipped with the necessary equipment and having a complex of facilities to ensure favorable conditions for technical service. (Research purpose) The research purpose is in identifying opportunities for updating the technical service system in the agro-industrial complex by creating innovative service centers to ensure highly efficient operation of agricultural machinery and equipment. (Materials and methods) The system of maintenance in agriculture is characterized by a significant decrease in efficiency due to physical and moral wear of equipment of repair and technical enterprises, low level and insufficient qualification of personnel and managers of enterprises of the agro-industrial complex. The availability of existing enterprises of the agro-industrial complex with production areas is no more than 50 percent, technological equipment is no more than 47 percent, and technological equipment and equipment for jobs are 15 and 40 percent. (Results and discussion) The modernization of the infrastructure of technical service of agricultural machinery is aimed at updating the technological base of machine repair. Repair and technical enterprises do not have the necessary equipment to perform a number of maintenance and routine repairs. The process of developing technical service infrastructure is significantly behind the level of structural and technological complexity of agricultural machinery. Due to technological requirements, complex components and assemblies, such as engines, hydraulic equipment, fuel pumps of domestic and imported agricultural machinery should not be repaired in the conditions of farms. (Conclusions) The high technological level of innovative technical service centers serves as a condition for efficient operation of production, ensuring its stability and reliability of operation, flexibility and adaptability, high intensity and waste-free operation.

Abstract In this paper, an algorithm for multipath connection provisioning in elastic optical network (EON) has been proposed. Initially, the algorithm prefers the single-path routing for service provisioning. But when single-path routing is not adequate to serve a dynamic connection, the algorithm switches to the connection request fragmentation. Its computation is based on the parameters such as capacity_constant and capacity_allowed to fragment the connection request on disjoint paths. Simulation results clearly state that the proposed algorithm performs well in service provisioning as compared to the traditional single-path routing algorithms and improves the average network throughput. Thereafter, we have investigated the limitation of Erlang B traffic model in EON for calculation of link blocking probability using routing and spectrum assignment (RSA) algorithm. It is verified by the following two ways: (i) effect on the blocking probability in case of constant load and (ii) effect of slot width on the blocking probability. Our simulation results indicate that in EON due to dynamic RSA, blocking probability is not constant in case of proportionate varying of call arrival and service rate giving constant load and blocking probability depends on the number of slots per link, but in Erlang B traffic model blocking probability is always constant in case of constant load and it considers wavelength per link instead of slots per link. This is attributed to the fact that Erlang B traffic model fails to calculate blocking probability accurately in EON. We have computed the carried traffic on 14 nodes, 21-link National Science Foundation Network (NSFNET) topology.
