In this article, on the basis of phenomenological
consideration of kinetic processes in semiconductors
volume, we have conducted an analysis, in order to
estimate the drift and diffusion components of the
output current for hot carriers in the total output of
the conductivity structure of the chip. The result
revealed amplitude and frequency characteristics of
this component of the conductivity, illustrating a
greater amount of its modulus and phase inversion
near the field-strength values of Ghan effect. This
can be used for designing oscillators of millimeter
range of wavelengths. It is shown that the nonlinear
diffusion component along with the drift is important
for the output conductance of the test specimen

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
The article presents data on the development of
recipes and technologies for the production of
functional drinks based on cabbage juice. Theoretical
and experimental justification of the selection of
ingredients of plant origin for the modeling of drinks
with a high content of pectin substances is offered in
the article. The use of carrots, beets and cranberries is
considered as an additional raw material for the
purpose of expanding the range and improving the
organoleptic properties of beverages. The fractional
composition of pectin substances used in the raw
materials was studied. The expediency of introducing
concentrates of pectin substances into beverage
recipes, which define the functional properties of
beverages and their optimal content in the recipes
was determined. The characteristics of basic
parameters of new drinks based on cabbage juice are
given. The results of the study of the complex
forming property of the developed beverages, which
confirmed their functional orientation, are presented.
Experimental studies have shown that the addition of
pectin increases the complex forming property of
juices. Complex forming ability of cabbage juice
with beet pectin in comparison with the control
sample and other samples is the highest. Taking into
account additional complex of biologically active
compounds based on cabbage juice, this product can
be used as therapeutic, prophylactic and
chemoprotective

For different industries, there was a need of creation new equipment and mechanisms with enhanced characteristics. Special requirements are imposed to energetic and mass-dimensional indices of systems of electric drives as one of the main components of such devices. Mass-dimensional and energetic indices due to constructional features and the used management system will allow improving the use of special or controlled asynchronous cascade systems of an electric actuator of axial construction. One of the main difficulties is simulation and design of special systems of the electric drive. In the article, we offer a new approach to determination of magnetic model parameters of the stator of a component of a controlled asynchronous cascade electric actuator of axial construction
An algorithm for obtaining a complex of mathematical
models of electromechanical devices, which can then
be formalized and implemented in software, is
proposed and described. Until recently, the
implementation of this algorithm was possible only
with the manual derivation of all expressions, which
significantly hampered the work of researchers. The
appearance of such programs as Maple, Mathematica
and MathCAD provided the possibility to automate the
process of obtaining analytical calculations that allows
calculating any modes of any types of
electromechanical devices, reduces the likelihood of
errors and allows you to change accepted assumptions
and designations in the developed models. The choice
of the MathCAD program (in comparison with Maple
and Mathmatica) can be justified by the fact that
MathCAD has the most convenient interface, allowing
not only to perform mathematical calculations, but also
to present the results in ordinary mathematical
notation. The analytical results obtained in MathCAD
can be immediately included in numerical models
This article discusses the results of the study to determine the impact of different primary tillage and herbicide against weeds in winter wheat agrocenosis. The task of the research was to determine the impact of primary tillage (moldboard plowing and surface treatment) factor A and herbicide (Lancelot) factor B on the agro-physical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period of winter wheat in 0-100 cm of soil layer didn’t depend on the method of tillage. Introduction of herbicide Lancelot boosted the moisture reserves in soil compared to the control type, in the herbicide-free type the weeds absorb the large amounts of moisture. Surface soil treatment did not have negative effects on soil agro-physical properties and its structure in comparison with moldboard plowing. Number of agronomically valuable aggregates on moldboard plowing is 85.2 - 87.5%, on surface one is - 86.2 87.5%. Density of composition and waterproof aggregates under surface treatment didn’t defer to tillage. Accumulation of wet and dry mass by weeds regardless to the way of soil tillage declined to a minimum when introducing the herbicide Lancelot. The high yield of winter wheat was obtained on this type. Mathematical processing results have shown that due to factor A (main soil tillage) to moldboard plowing the average productivity is 57.5 kg/ha, on surface one is 56.0 kg/ha, i.e. the difference between treatments is 1.5 t/ha (with NSR05 on factor - 2.9 t/ha) is insignificant. To factor B (herbicides) on control the productivity is 54.5 kg/ha, introduction of Lancelot increased the productivity to 59.5 t/ha, i.e. the increase was 5.5 kg/ha at NSR05-by the factor B-2.9 t/ha, i.e. is significant. Thus, the present soil treatments had no effect on yield of winter wheat in ordinary black soil. The use of herbicide Lancelot has produced the harvest increase in 0.5 t/ha on average for 2 years
