The article presents results of research of quality,
safety and content of biologically active substances of
food red beet roots of Bordo 237 variety, grown in the
Krasnodar region in 2014. On the basis of the research
carried out it was established, that there are
carbohydrates, proteins, organic acids and mineral
substances in the food red beet roots of Bordo 237
variety. Food red beet roots are a source of dietary
fibers (pectin, protopectin, hemicelluloses and
cellulose), possessing antitoxic, antioxidant, radiation
protective, cholesterol-lowering and lipid correcting
qualities, and also a source of vitamins C, B9 (folic
acid) and P-active substances, possessing antioxidant
properties. Due to high content in food red beet of a
complex of microelements – iron, zinc, manganese and
copper, and a complex of macro elements – potassium
and magnesium, it can be recommended for
prophylaxis and treatment of hypertension,
atherosclerosis and other diseases of heart and vascular
system, and for prophylaxis of iron-deficiency anemia.
Thus, the research of quality, safety and content of
biologically active substances showed that food red
beet roots of Bordo 237 variety are a high quality component ingredient for creation of food products of
specialized and functional purpose
The article presents an overview of the run-in and testing
of internal combustion engines, the analysis of
break-brake- stands. We gave recommendations on
expediency of the application of asynchronous motors
with phase rotor winding on modern stands; we also
considered its advantages over asynchronous motor
with a short-circuited winding. As an alternative to the
modern techniques, we have proposed a scheme of
adjustable ballast circuit rotor using PWM modulation
current. The process of adjustable ballast resistance
and implementation of major break-regimes using the
proposed device was also considered in this study
The article presents the results of studying of prospects
of use of the relative screw and combined drums in
agro-industrial complex. The developed and approved
classification of the relative screw and combined drums
has been shown in expanded form. The kinds of the
equipment on the basis of the relative screw and
combined drums making a rotary motion in which the
oscillating motion with a big amplitude, only at the
expense of an original spatial form of their internal
surfaces is reported to subjects of processing are
presented. In such devices, there are no vibroactivators.
Equipment samples in which the relative screw and
combined drums aren't rotated are also presented. They
are fixed elastically on the bed and are supplied with
vibroactivators. During the operation of the
vibroactivator, processing subjects in such cars, as a
result of the circulating movement in the relative screw
and combined drums in the planes, perpendicular axes
of their symmetry, receive the additional movement
from the walls of drums of various geometrical forms
inclined to each other
The article presents the experience of creation of the
equipment on the basis of the relative screw and
combined drums providing highly effective
technological processes, because for such drums it is
characteristic not only creation of fluctuations to
processing subjects with an amplitude of movement of
15-1000 mm and more, but also the opportunity to
operate oscillatory process, changing transport or
technological effect. Therefore, works on creation of
the equipment, for realization of such technological
processes, are extremely important and actual for
dehydration of manure, drying of chicken dung, and
for preseeding processing of seed material. We present
kinds of the equipment in which vibroactivators are
absent. Equipment samples in which relative screw
and combined drums aren't rotated are also presented.

The article reveals a possibility of using equipment
based on relative screw and combined drums for
mixing of bulks. Change of relative positioning of flat
elements of sidewalls of internal surfaces in relative
screw drums allows operating the difficult and spatial
movement of streams of bulks. In relative screw
drums we have developed effective processes of
mixing and sets of the equipment, which are
characterized by that fact the difficult and spatial
screw movement taking place in relative screw drums
is dismembered on rather simple, in the kinematic
relation, in the movements. The difficult and spatial
screw movement with a big amplitude of 15-1000 mm
and more, in the offered equipment constructions on
the basis of relative screw or combined drums, is
reported to bulks by elements of the relative screw or
combined drums of various parameters and
configurations which becomes complicated also screw
lines on perimeter of a relative screw drum with
various number of calling and the directions from each
other or rounds of the springs fixed in the relative
combined drums
This article presents an algorithm based on the discrete
wavelet transform for the analysis of current root mean
square (RMS) value and total harmonic distortion
(THD) in power systems. Power quality indices play
an important role in case of non-stationary distorted
waveforms, where neither a frequency-domain-based
approach using fast Fourier transform tools nor a timedomain-based
approach using real time data give
satisfactory results. The algorithm proposed
decomposes the current waveforms into uniform
frequency bands corresponding to the odd harmonic
components of the signal. The proposed algorithm
overcomes the spectra leakage problem. Computer
simulations verified the effectiveness of the proposed
algorithm
The article describes the basic techniques for working
with Kontrol automated monitoring system. We suggest

software settings-governmental applications,
technologies used in the tests of text, graphics and
multimedia data
Basing on brief-analysis of nature-climate and economical conditions conformed for field-production in Russian agriculture, needfulness of finding of new ways, one of that is reducing of number of mobile technologic special-purpose equipment and its removing with advanced universal energetic techniques is presented. The results of design of modern constructive decisions of new-generation schemas of universal energetic machineries are presented. The algorithmprogram package, designed in our institute, was used during calculation of economical efficiency of machines complexes based on universal energetic techniques. Estimated effect of using machinery in south of Russia was evaluated through comparing costs creating by optimal machinery parks of typical farms of eleven sub-zones, filled with serial machines, vs. field complexes based on universal energetic machine
The aim of the work is theoretical and experimental
confirmation of the possibility of improvement in
tractor unit acceleration due to the variable inertia
moment of the rotating masses of the engine. The use
of high-speed tractors in agricultural production
meets a number of difficulties associated with unsteady
processes during acceleration of the tractor
units. The emerging significant inertial loads during
acceleration result in the loss of engine power because
of what the machine and tractor unit is operating
at reduced productivity and efficiency. An analysis
of published works shows that the tractor unit
acceleration is strongly influenced by the rotating
mass of the engine. A device based on the application
of additional rotating masses in a free flywheel
connected or disconnected automatically to the main
engine flywheel at appropriate stages is offered. As a
result, the tension during acceleration is reduced.
The results of experimental studies on the effect of
the additional rotating masses on the engine acceleration
characteristics of the machine and tractor units
on the basis of Class 1.4 tractor are given. It is
proved that the use of the tractor additional rotating
mass connected or disconnected to the respective
modes of movement of a machine and tractor unit to
the flywheel of the engine, improves acceleration
performance
The article considers the existing at the present stage
of management approaches, describes their advantages
and disadvantages. We have obtained scientific and
special management approaches. Of all the approaches
described in detail, we could highlight system,
integration, dynamic, structural, functional and process
approaches. It was indicated, that the use of the above
approach to production management, as a whole, and
the staff in particular - is limited to the economic
sphere of activity, meanwhile, as there is a prospect of
using these approaches in the field of labor protection.
We also substantiate the choice process approach as
the most promising in the management staff of
mechanical engineering enterprise
