THE RATIONALE FOR THE USE OF COMBINED UNITS IN THE CULTIVATION OF WINTER WHEAT
06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionIssues related to the use of combined aggregates in soil preparation are relevant and of scientific and practical interest. The relevance is increased when it comes to the cultivation of the main crop – winter wheat. In this regard, the presented results on the efficiency of using combined aggregates in preparing soil for winter crops are important primarily from a practical point of view. Experimental studies were conducted in the conditions of long-term stationary experience in the Federal state budgetary institution «Agrarian Science Center «Donskoy», Zernograd, Rostov region. The article considers the efficiency of using the combined unit APK-4, developed in "SKNIIMESH" now Federal state research institution of the «Agrarian Science Center «Donskoy» in the cultivation of winter wheat. The structural and technological scheme of a combined unit, the technological process of which consists of several technological operations performed at the same time, is justified. Disk working bodies crush plant residues and destroy weeds. This creates a network of cracks in the underlying soil horizons. Next, there are flat-cutting working bodies that loosen the soil to a set depth. The root system of weeds is pruned, the remaining loosened soil layer is loosened to the required depth, the formation of a smooth bottom of the "furrow", and the separation of erosive soil particles to the bottom of the furrow. Next, the roller starts working – a lump-crushing sealer, which provides crushing of soil lumps on the surface and sub-compaction of the treated layer. The last in the technological chain is a mulching roller, which provides the formation of a compacted seedbed for seeds with simultaneous mulching of the compacted soil layer. The use of the combined unit in the technology of winter wheat cultivation allowed to reduce the number of technological operations by 1,5-2,5 times, increase the productivity of winter wheat by 11-13% and the cost of production by 10,4-18,3 %

THE RATIONALE FOR THE USE OF ELECTROMAGNETIC FIELD IN THE PRODUCTION OF SUNFLOWER OIL
01.00.00 Physical-mathematical sciences
DescriptionIn some works, the feasibility of the use of fixed and variable electromagnetic fields of different frequencies and tension in the production technology of sunflower oil are shown, but there is no theoretical justification. The possibility of electromagnetic effects is associated with the presence of polar molecules specific to organic systems. Without prejudice to the role of polar groups of terrestrial circuits, this work tries to address this challenge more comprehensively. The reason for this is the distinctive feature of the behavior of sunflower during its flowering. This characteristic is that the sunflower hat during the day changes its direction in accordance with the direction of movement of the Sun across the sky; so called "magnetism" of their attraction. To justify this effect, we have analyzed the essence of emitted photons, the Sun chemical composition and structure arrangement of seeds in a sunflower hat. Particles of light from the Sun represent a stream of photons - a wide range of electromagnetic waves of frequencies that exhibit and magnetic properties. The article shows principal macro- and micronutrients of sunflower raw materials and divides them into groups of para- , dia- , and ferromagnetic materials. In sunflower seeds, there are chemical elements: diamagnetism-C, H, N, P, S, B, Cu, Zn, J; paramagnetism-O, K, Ca, Mg, Mo, As and ferromagnetic-iron (Fe). As there is resultant force of the magnetic attraction between the sunflower hat and magnetic flow of photons from the Sun, this effect dominates the action of paramagnetics K2O ( -28.4 24.5%), CaO (7.6-17.0)%, MgO (12.3-17.9%), magnetized in an external magnetic field in the direction of the field. The presence of evident effect demonstrates that it is possible to improve a number of technological operations in the manufacture of sunflower oil using electrical, magnetic or electromagnetic fields

05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionThe article presents a methodological approach to the rational selection of the optimal working width by the example of a combined tillage unit using original software. To select the optimal working width of a combined soil cultivating unit, the initial data are: make (type) of the tractor (power tool), unit cost of the machine and tractor unit in comparable prices, production time of the machine and tractor unit to perform the technological operation at a given operating speed with a clear compliance with agrotechnical requirements, both to the technological operation itself, and, directly, to the agricultural machine. As an example, we consider a combined semi-mounted modular tillage and sowing unit for grain crops and the MTZ-82.1 tractor. In this unit, the main working bodies are S-shaped spring teeth and rollers. Based on the performed analytical studies of the pre-sowing (surface) tillage process and the application of theoretical modeling methods, mathematical dependencies have been developed to determine and further analyze the energy-technological parameters of combined tillage units with dynamic working bodies. The performed calculations according to the developed method allow us to choose the optimal working width of the combined soil cultivating unit

Description
Nowadays there is a deficit of irreplaceable and physiologically necessary nutrients in everyday ration to a large extent connected with unfavorable environmental conditions and the increase of morbidity of humans of all ages cause the cute necessity in the creation of functional food that is products with additional functions which are healthy nutritive and physiological characteristics. One of the main demands under their creation is in the positive influence of introduced products on the food value of products because they must be enriched with ingredients which have antioxidant properties. Therefore, nowadays the introduction of functional meat-plant products will promote the effective improvement in the direction of prophylaxis of different diseases. In Russia, the concept of healthy nutrition became a part of state politics. The aim of this politics is the conservation and consolidation of population’s health and the prophylaxis of diseases. In this work, there was considered the technology of the production of meat-plant tinned food of functional purpose enriched with nutrients and intended for preventive human nutrition, for those who are in the conditions of harmful influence of environment and professional activity. There were described the advantages of the given developing, there were recommended the introduced into the product components of functional purpose

Description
The subjects of the study are the foundations of buildings with a high center of gravity, in particular, the foundations of high-rise buildings with developed upper floors due to the large consoles. From a set of loads, transferred to the high-rise building with a high center of gravity, we can highlight the most significant impacts, affecting the distribution of forces in the elements of the foundation. We reveal the factors playing a special role in the choice of design solutions for the foundations. The practical significance of this research is due to the demand for ground areas in the cities which are being developed, although they were previously considered unsuitable for construction. Today, one of the primary tasks for engineers and architects is increasing technical and economic performance of construction projects and meeting customers' requirements in the individual architecture. As a variant of increasing technical and economic performance of buildings in dense city building conditions is to use the arm structures in their design solutions that both low-rise and high-rise building can achieve the architectural attractiveness of the building and significantly increase the usable floor area. In the research, two types of the foundations were projected for the object which is an eight-apartment building in the ground conditions of Sochi. The analysis was carried out with such software as PC ING +. After receiving the results of numerical analyses we performed a comparative analysis of pile-slab and slab foundation with the seismicity of the construction site. Therefore, we have identified the most rational of two types of foundations

JUSTIFICATION OF RATIONAL USE OF VIBRATING TOOLS FOR SOIL CULTIVATION
DescriptionFrom a review of the literary sources it is revealed that the existing vibration exciters are classified into mechanical, electrical, hydraulic and pneumatic. One of the most promising areas of development and use of sources of vibrations for tillage tools are electrical exciters of mechanical vibrations namely solenoid with a metal core inside. Based on the analysis of existing technical means for soil cultivation we are proposed a new technical mean of vibration exposure for tilting the soil without or before ploughing. Theoretical regularities of change of draft resistance depending on the vibration amplitude and the mass of the vibration exciter were received in the studies. A structurally - technological scheme of the combined tillage combine with electric vibration exciter and a device for automatic regulation of the technological process of the work of tillage machine was developed. The proposed vibration tool will supposedly reduce the soil resistance force acting on the working bodies, which will reduce energy costs up to 20% for the technology process of soil cultivation; harmful emissions from the combustion of diesel fuel into the atmosphere were reduced. The proposed technical mean can be used for soil cultivation in different soil fertility under different soil density

Description
In the article, we present existing approaches to the study of the optimal composition of technological systems. We have justified a new method of improving the reliability and the efficiency of technological systems of grain harvesting based on application of mass service theory. An engineering methodology for the substantiation of structure of the technological complex of agro-climatic conditions has been developed. In this case, the basis is the method proposed by S. D. Shepelev and G. A. Okuneva. To justify the structure of the technological complex of agro-climatic conditions of the Krasnodar region we have developed a mathematical optimization model, as criteria of which the losses from downtime of combine harvesters and transport vehicles have been taken. On the basis of the developed technique co-dependence on the number of combine harvesters «Torum-740» from the capacity of vehicles and coefficient for their use for the Northern zone of the Krasnodar region has been found

JUSTIFICATION OF SUNFLOWER SEED CLEANING SCHEME ON AIR-SIEVE GRAIN CLEANING MACHINES
DescriptionA set of actions aimed at preserving seed quality is the task of primary importance, which is expected to produce effective results. To implement this task it is necessary to prepare high-quality seeds by cleaning and sorting sunflower seeds on air-sieve grain cleaning machines. To determine the rational scheme of cleaning sunflower seed piles of the ‘Lakomka’ variety on the air-sieve grain cleaning machine ‘MVU-1500’ a qualitative analysis has been carried out. Cleaning sunflower seeds is carried out by an air stream by one or two sieves for separating large impurities and by two sieves, one of which separates milled seeds into the overseeding ,with the second dividing the whole seeds. In such a scheme of cleaning sunflower seeds, purity corresponds to the 3rd class of seed material and has some disadvantages. The disadvantages are as follows: the gathering seeds in sieve Ø5.0 have low individual weight and the sieves show low quality of work. To facilitate the work of the sowing sieves a grading sieve is installed, which will separate 50% of the seeds into the gathering. The size of the openings in the grading sieve is selected with the help of the correlation table. The sieve for sunflower seed variety ‘Lakomka ‘will be Ø 3.6, which will select the most valuable seeds with weight above 90 g from the purified material thus improving the productivity and performance of the sowing sieves. A promising scheme of cleaning sunflower seeds is the air flow rate equal to 4.43 m/s, with one grading sieve of Ø 3.6 and two sieves of Ø 7 and Ø 3.6 mm in grain cleaning machines that will allow you to get high quality seed material that meets the requirements of GOST(Russian national standard) for seed material
