Tillage energy efficiency increase is one of the important tasks in improving the profitability and sustainability of agricultural production. The paper proposes to increase cultivation energy efficiency due to the use of traction-drive tilling implement with active working bodies, not creating a high traction resistance and not requiring a large towing weight of aggregated tractor. The analysis of the energy efficiency of soil cultivation using traction-driven tilling implements with active working bodies has been carried out, and theoretical dependences of the coefficient of efficiency of a traction-driven machine-tractor unit has been obtained. The possibility of increasing the efficiency of the unit by reducing slipping of the tractor wheels and losses on rolling of the unit has been determined, which has been achieved by transferring part of the power through the power take-off shaft (PTO) of tractor to the drive working bodies of tilling implement, which compensate for traction resistance of the implement and create a pushing force, reducing the resistance to rolling.

Abstract Stamping is employed in a wide range of applications including household appliances, automobiles, vessel, and aerospace. Due to the discrete flow energy-intensive processes and dynamic energy changes in stamping production, it has great potential for energy savings. There still lacks an effective method to monitor and analyze the energy efficiency in stamping workshop. To this end, this paper proposes an energy efficiency monitoring and analysis system based on Internet of Things (IoT). The characteristics in stamping workshop are first analyzed, the energy consumption is decomposed, and the makespan is quantified. Besides, energy efficiency indicators of energy efficiency in the press machine, specific energy consumption in the part, and energy efficiency in the workshop are analyzed and defined. Then the detailed information about the energy efficiency monitoring and analysis system as data acquisition, data transmission, data storage, data analysis, and display based on IoT is presented. Finally, a forklift stamping workshop was investigated to validate the effectiveness of the proposed method. The interface and the results of the data analysis showed that the proposed system can monitor the energy efficiency in the stamping workshop comprehensively. Furthermore, potential opportunities for energy consumption reduction and efficient production can be identified.

In the article technological methods energy and economic evaluation of growing sage in southern steppe of Ukraine conditions have been analysed. The economists’ views on the raw medicinal herbs under drip irrigation formation of efficient production have been considered. The analysis of previous agronomic studies on the cultivation of crops under drip irrigation has allowed us to conclude that there are no such results on the plantations of Salvia sclarea. The yield level of Salvia sclarea inflorescences was stable during the first three years of using, on the average in the first year it was 9.51 t/ha, in the second year it was 9.38 t/ha, in the third year it was 9.69 t/ha. Only in the fourth year of crops using (the fifth year of life) the yield was decreasing sharply. On the basis of yield data, the calculation and analysis of such indicators as energy efficiency, energy intensity of growing 1 kg of inflorescences and the conditional net profit when growing sage in drip irrigation in southern Ukraine. The maximum values of energy efficiency ratio were obtained in the first year of using and sowing in the first decade of December against the background of N60P90 - 3,25 application. When the crops sowing was postponed to the first decade of April, this indicator decreased twice to 1.59. In our experiment the minimum values of energy ratio of Salvia sclarea growing technology were obtained in the fourth year of plantation using. The classical indicators which reflect the economic and energy efficiency level of inflorescences of nutmeg production at long-term use of a culture plantation culture have been analysed. The analysis of the factors which influence for efficiency change of cultivation of culture was carried out. The mechanism of efficiency increase of cultivation of sage nutmeg in the conditions of the southern Steppe of Ukraine has been offered.

This paper presents the Least Energy Demand as an independent reference value for evaluating energy efficiency of additive manufacturing (AM) processes. Nowadays an essential challenge is represented by a proper evaluation and calculation of the energy efficiency of production processes. The reason for this is the lack of appropriate reference values. A comprehensive comparison of the energy efficiency is not possible without consistent reference values. However, this comparison serves as a first step towards the goal in order to reveal the actual energy savings potential of additive manufacturing procedures and to take actions on this basis. Therefore, as a first step the basic concept of the additive manufacturing principle is introduced. Subsequent the scope of the current research regarding the considered additive manufacturing techniques is illustrated. Afterwards the general system of the Least Energy Demand is presented, which serves the needs in terms of evaluating the energy efficiency of additive manufacturing processes. To sustain the comparability of the Least Energy Demand between the presented AM-procedures a solid basis for further calculations is established. Finally this paper concludes with the results of the calculated Least Energy Demands for the individual additive manufacturing processes and a comprehensive energetic comparison.

The historical context in which the State Plan for Electrification of Russia (GOELRO) was developed, establishment of the GOELRO Commission, the GOELRO Plan content, the specific features of its implementation, and the role of the plan in the soviet period of Russia’s history are considered. Attention is paid to the electrification plants of other countries and territories of all inhabited continents, and to the participation of states in the electrification of countries and regions with small-scale and agricultural production in the 1920 s. The specific features pertinent to the electrification of the Russian Socialist Federative Soviet Republic are pointed out, namely, low starting conditions (in 1923, the energy consumption per capita in Russia was 100 times lower than that in Norway), its being state-owned in nature and revolutionary in its purpose: to get done with the main upheavals in the country and to shift the national economy for fore efficient production. The role of V.I. Lenin and G.M. Krzhizhanovsky, who were the initiators of the electrification of Russia, is analyzed in detail. A conclusion is drawn about the need to study both the GOELRO Plan itself and the specific features and circumstances of its implementation within the framework of training modern specialists in electrical engineering.

The Relationship

The article discusses a non-standard view of the formation of human capital for work in organizations of the agricultural sector of the economy, in the context of modern socio-economic transformations. In the classical sense, human capital for agriculture should be formed and developed in rural areas. But in real life, this is not always the case, because there are many factors that prevent the classical solution of this problem. First, the demographic factor affects, second, social and household factors, and third, in many rural areas there are no working agricultural organizations where qualified agricultural specialists can work. All these and other circumstances actualize the problem of the quality of human capital in rural areas in relation to the development of agricultural production.

Urban Complex

This study quantified the improvement in energy efficiency following passive renovation of the thermal envelope in highly inefficient residential complexes on the outskirts of the city of Madrid. A case study was conducted of a single-family terrace housing, representative of the smallest size subsidized dwellings built in Spain for workers in the nineteen fifties and sixties. Two units of similar characteristics, one in its original state and the other renovated, were analyzed in detail against their urban setting with an experimental method proposed hereunder for simplified, minimal monitoring. The dwellings were compared on the grounds of indoor environment quality parameters recorded over a period covering both winter and summer months. That information was supplemented with an analysis of the energy consumption metered. The result was a low-cost, reasonably accurate measure of the improvements gained in the renovated unit. The monitoring output data were entered in a theoretical energy efficiency model for the entire neighborhood to obtain an estimate of the potential for energy savings if the entire urban complex were renovated.
