The aim of the study was to improve evaluation of the uniformity of irrigation with a machine of continuous translational motion, according to the test results of the apparatus with radial methods. Research method – mathematical modeling of the running of four machines of circular actions on a device of continuous translational motion using the result of the tests of the device with a radial method. The algorithm of calculation, recommended by the standard ISO 7749-2-2004, has been improved to minimize manual calculations and measurements. The algorithm is implemented in a computer program. Program of CDU(B) implements an advanced algorhythm. The program calculates a matrix of irrigation doses on meter squares area of spray irrigation between the positions of the two devices. The progressive movement of the machine is modeled by summing the doses in column-major order with constant X. At vector doses after the passage of the machine, it calculates the coefficient of uniformity of irrigation by Christiansen. The calculation is performed at different steps of the installation of devices, and so it determines the optimal location of them. The improved algorithm of calculating the figures of sprinkling uniformity using the test results for devices using a radial method was implemented in the program of the CDU(A) [1]; it allows to choose the optimal step for installation of devices. The algorithm of calculating the uniformity in the step of installation of the apparatus on the pipeline which is greater than the radius of the irrigation apparatus simulates the operation of two devices. During the installation step of the apparatus of smaller radius than irrigation apparatus, we model the work of four adjacent devices. The optimal step of installation of i-Wob is 14.5 meters, which is 1.75 times greater than the radius of the irrigation system and 1.5 times greater than the pitch of stationary devices with the same tolerance on the uniformity. Two-nozzle devices, which assessment standard does not meet the requirements of the uniformity of irrigation at the drive of the translational motion ensures a better distribution in the pitch of less than 24 meters

A 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
Gardening is one of the high-value and highly profitable
branches of agriculture. However, the level of fruit
production in Russia still lags far behind the needs of
the population: 20-25 kg of fruits and berries per year
are grown per capita, which is a quarter of the minimum
consumption rate. Currently, domestic gardening has a
low efficiency due to non-compliance with the criteria
of world production of fruits. The production of gardens
is not competitive enough and does not meet the
requirements of the highest quality categories of
domestic standards. To increase fruit production, it is
necessary to increase the level of intensification of fruit
growing using the most valuable varieties and
progressive technologies of cultivation. In this article,
we consider devices for soil content in orchards, as well
as for pruning trees - the main agrotechnical techniques
in the technology of growing pomegranate crops that
promote the production of stable, optimal harvests of
fruit crops. The universal device of fruits is also covered, which makes it possible to reduce labor costs
during the laying, care and harvesting of the fruit
garden. The wide development of intensive
technologies for growing fruits adapted to specific
climatic conditions and ensuring a high level of
competitiveness and profitability of production is one of
the necessary conditions for the further development of
gardening in Russia
In this article, we consider approaches to the transfer
of knowledge to students and an objective
semiautomatic assessment of knowledge. The
characteristic features of the application and the
possibility of using cognitive training methodologies
and complex systems for testing skills and the
theoretical base of trainees are analyzed. The
problems of development of this direction and
possible ways of their solution are described. The
basic concepts are introduced and the existing
methods of calculating the average score for
checking the student's knowledge are considered,
and a new approach to solving this problem is
proposed. Based on the conducted researches it is
offered to use the complex system of testing of end
users, which includes testing, monitoring, collecting,
analyzing and displaying the results of
students/groups/ course. The main requirements for
the creation of such a complex and the rules to be
followed are formulated for a more objective
assessment of knowledge. A model of an integrated
modular system for objective semi-automatic testing
of knowledge through testing is described

information exchange, as well as comfort for users
The article considers a combination of the process-based and systematic approach in the management of OSH at the enterprise for the development of the OSH management system model. The OSH management system is created by the enterprise based on the model provision, the branch requirements and recommendations of the current standards. Features of the system are determined by the state of the external and internal environment of the enterprise (context). The context forms the basic requirements for the inputs of the system and determines its capabilities. An analysis of the context of the enterprise makes it possible to identify the system: describe its inputs and outputs, identify key stakeholders and consumers. Based on this analysis, a model of the OSH management system is suggested, which, in analogy with the modern model of the quality management system, allows us to identify the place of the OSH in the context of the organization, and also to clarify the interaction of the main groups of OSH
The mechanical activation allows creating a active
state in a solid, opening the prospect for holding and
accelerating the chemical reactions between solids and
getting materials in a nonequilibrium state. As a result
of mechanical activation of the powder compositions
of the active phase transformations occur in them,
which lead to the formation of solid solutions and
various intermediate connections, providing dispersion
and dispersion hardening of materials included in the
composition. The results of the study of the
granulometric composition, the phase transformations
and structure evolution in multiphase materials with
SME Ni-30%at.Ti-20%at.Hf and Ni-33%at.Ti-
18%at.Zr at different stages of the process of
mechanical activation carried out in planetary ball mill
the centrifugal type is represented in the article.
During mechanical activation, a composite mix is
assimilated by the particles of processed material input
of mechanical energy in the form of new interfaces,
defects of the crystal lattice. At collision of particles
and grinding bodies in contact high local temperature
and pressure occur, which in some cases can lead to
melting of the most fusible components. When a local
increase in temperature between the particles of
titanium, hafnium, zirconium and carbon solid-phase
reactions become possible due to diffusion of atoms of
one component into the crystal lattice of the other.
Experimental studies have shown that the use of
mechanical activation allows creating an effective
technology of preparation of the starting material for
high-speed flame spraying
The article deals with the study of vehicles impact on
the environment, since one of the main causes of air
pollution are cars with internal combustion engines.
One of the most important measures in the fight for
clean air is the creation of an environmentally
friendly transport. From this point of view, the most
promising is the electric car, as the only solution to
the problem of atmospheric pollution. In this article,
the history of the development of modern electric
vehicles, the advantages and disadvantages of their
design, as well as the possibility of introducing
electric vehicles into everyday life are considered.
After the analysis, it was concluded that, in spite of
the obvious advantages and the huge path that electro
mobiles went through in their development,
humanity is still not ready to refuse from cars with
internal combustion engines, opting for electric
vehicles
