At present, the preparation of the soil for the hop plant with machines of traditional hop production technology is unrealistic, since there are no more hops and no one is producing them. In this regard, a progressive technology for growing hops and promising machines for them, including for energy-saving tillage for hops, have been proposed. As the main cultivation, two-strip soil cultivation was used for rows of hops with a combined subsoiler-drener developed at the Chuvash State Agrarian University. Moreover, loosening is carried out with the simultaneous introduction of liquefied litterless manure with a dose of 100-120 t / ha to the subsurface zone from 0.20 to 0.60 m. In the soil, liquefied litterless manure fills the drainage canal and the soil pores adjacent to the canal, activates the activity of microorganisms and soil biochemical processes. Row loosening with a combined machine allows to reduce the energy consumption of processing by 57% compared to continuous plowing with plantation plows and to exclude the operation of applying bedding manure with subsequent moldboard embedding. As a pre-planting soil preparation, cultivation with combined stubble cultivators of the KST-3,8 type and its analogues with the incorporation of crushed green manure (up to 75%), high-quality leveling and crumbling of the soil is proposed. Stirring and leveling of the field surface is provided by afrontal discs behind the last row of flat-cut tines, crumbling - by a ribbed roller. The maneuverability of such a cultivator in the cramped conditions of the hop is taken into account. Replacement of plowing operations with general purpose plows and subsequent leveling by a cultivator allows an additional 45-50% reduction in the energy intensity of pre-planting soil cultivation. The main energy source in the main tillage is the tractor BTZ-243k

Compression Time

: In the fast development of information, the information data is increasing in geometric multiples, and the speed of information transmission and storage space are required to be higher. In order to reduce the use of storage space and further improve the transmission efficiency of data, data need to be compressed. processing. In the process of data compression, it is very important to ensure the lossless nature of data, and lossless data compression algorithms appear. The gradual optimization design of the algorithm can often achieve the energy-saving optimization of data compression. Similarly, The effect of energy saving can also be obtained by improving the hardware structure of node. In this paper, a new structure is designed for sensor node, which adopts hardware acceleration, and the data compression module is separated from the node microprocessor.On the basis of the ASIC design of the algorithm, by introducing hardware acceleration, the energy consumption of the compressed data was successfully reduced, and the proportion of energy consumption and compression time saved by the general-purpose processor was as high as 98.4 % and 95.8 %, respectively. It greatly reduces the compression time and energy consumption.

The basic soil preparation is an important factor in ensuring high survival rate and preservation of cultural plants. Its objective is to loosen the soil to a predetermined depth, it is also important to ensure the containment of weeds growth in areas, adjacent to the row of crop strips. Depending on soil conditions it may be cutting of one or double earthboard furrows (drained soil) and in the formation of microhill (temporarily waterlogged soils). For these purposes, currently, ploughs PKL-70, PRL-70, PL-1, PLM-1.5A, PDV-1.5, PL-2-50, PLD-1.2, etc. are used. Their common drawback is the ability to perform only one operation. A large variety of used tillage equipment and its low efficiency confirms the urgency of developing multi-tools modular construction. This will effectively produce basic preparation of the soil in a variety of conditions with a single instrument. The article provides a description of design and basic layout options of multifunctional plough. By simple changeovers, carried out on site, the plough can be adapted for the main preparation of soil on clearings with drained and temporarily waterlogged soils. It is also possible to change the distance between the bodies of the plow in accordance with the specified rows and rearrange them to work "in" or "out". Process works is modeled in conditions of non-uprooted cutting. The simulation experiment showed high efficiency of the plough, which is ensured by the presence of safety recoverable devices. Replacement in the forestry enterprise of a set of ploughs with one multipurpose plough will reduce total specific amount of metal almost in 4 times.

The paper considers the issues of reducing the energy intensity of transportation at opencast mining enterprises, the relevance of which has now increased due to the rise in the cost of fuel and energy resources. It presents the study results concerning the cost structure of the electricity consumed by electric mine transport, which form the basis for the development of technical and operational measures to reduce the energy intensity of the transportation process. It is shown that the work to reduce the electricity consumption for mined rock transportation should be aimed at: Reduction of losses in the power circuits of the traction rolling stock due to the use of more advanced electric rolling stock and regulation of the degree of utilization of the installed traction power; Introduction of new contact materials for electrical circuits with the lowest possible resistivity, including for current collector plates; Introduction of measures to reduce energy consumption for power supply of auxiliary circuits; Development and implementation of rational train control techniques. The introduction of energy-saving measures should include the development and application of effective methods for calculating individual norms of energy consumption and incentives for energy saving of the employees involved in the organization of the transportation process.

The relevance of the research topic is that energy-saving is the key element of modern energy development in the country. In Kazakhstan, energy-saving, and improving the energy efficiency of agriculture is currently a priority task that will solve energy, environmental and economic problems. Without a solution to these problems, the country's development will inevitably hold back. The head of state in the field of energy conservation has set a goal to reduce the energy intensity of the gross domestic product by at least 25% by 2020, and annual energy-savings of 3.5% after 2020. Industry in rural areas consumes more than 70 % of all electricity. As part of the comprehensive plan, their energy audit was conducted 50/50 (50 % of the financing is the enterprises' funds, the remaining 50 % is the state budget). As a result of the energy audit, systematic measures were developed to reduce the energy intensity of the industry, including the electric power industry. Large unproductive losses of energy resources are in the private sector, in this connection, since 2019, the energy audit of JSC "Kazakhstan center for modernization and development of housing and communal services (housing and communal services)" is conducted on budget funds in the private sector. Energy conservation is one of the most important and strategic tasks of the country. Rapidly developing production requires additional energy costs. This is confirmed by the annual increase in energy tariffs. In turn, resources are not unlimited, and their irrational consumption will inevitably lead to not only economic but also to an environmental crisis.

Technological Intensity

This paper analyzes structural indicators of economic efficiency and energy intensity consumption as determinants of sustainable economic development for the selected 33 European countries. The correlation, regression and multivariate factor analyses are applied to test the associations between the selected structural variables of energy intensity consumption, economic efficiency, and the main driving forces behind these developments. Economic efficiency is positively associated with expenditures on research and development (R&D) and a greater technological intensity of exports, while at the same time the economic efficiency of R&D expenditures and technological intensity of exports reduce the energy intensity consumption of the economy. The results suggest that management strategies and policies directed towards R&D expenditures, human capital investments, and technologically intensive export oriented products are improving economic efficiency performance and contributing to energy saving sustainable economic development. The technological intensity of products reduces energy consumption, which is related to restructuring of energy intensive industries into more advanced and energy saving ones with higher value added per unit of product, but with lower energy consumption per unit of product. Santrauka Autoriai analizuoja struktūrinius ekonominio efektyvumo ir energijos vartojimo intensyvumo, kaip vienų iš pagrindinių subalansuotos plėtros kintamųjų, rodiklius. Tirti buvo pasirinktos 33 Europos valstybės. Autoriai, siekdami pagrįsti iškeltus teiginius, naudojo koreliacinę, regresinę analizę bei daugiakriterinius metodus galimoms ekonominio efektyvumo bei energijos vartojimo laipsnio (ir kitų, ne mažiau svarbių elementų) variacijoms nustatyti. Ekonominis efektyvumas labai dažnai asocijuojasi su tyrimais ir plėtra (R&D), eksportuojamomis aukštosiomis technologijomis. Remdamiesi atliktų tyrimų rezultatais autoriai siūlo nukreipti tiek politinius sprendimus, tiek valdymo strategijas į tyrimų ir plėtros (R&D) veiklas, investicijas į žmogiškuosius išteklius, technologinius sprendimus, nes visa tai galima susieti su subalansuotos plėtros koncepcija.
