The article presents the basic concepts, classification
of SCM systems and the field of application of this
management technology. The analysis of the
international and Russian market SCM-systems,
allowed us to choose the five most popular
alternative information systems of this class. For the
procedure of selection of the information system have
been developed criteria, oriented to the demands of
corporate integrated structures. For each criterion
there was determined a value coefficient. This stage
of research was carried out with the involvement of
heads of corporate integrated structures, experts in
the field of it and scientists of Kuban state agrarian
University. As a result of the assessment, we have
chosen an information system called "SAP SCM
EWM" with the highest number of points. The study
of the functional information system was carried out
by building a complex chart of precedents (the
modeling language UML, tool Microsoft Visual
Studio 2012). Generalization of experience of
consulting and analytical companies allowed to
allocate the main stages of implementation for SCM
systems and to develop recommendations for their
implementation. The study has practical value for the
integrated corporate structures from the standpoint of
managerial decision-making of choosing an
information system of type SCM and introducing it
into their operations
In the article we have considered the self-balanced
potato sorting machine differing from existing designs
of self-balanced potato sorting machines with an oscillatory
electric drive. That drive uses a linear induction
motor. As the counterbalancing device, the method of
the duplicating mechanism is applied. The duplicating
mechanism is a specular reflection of the main working
body, and also participates in technological process.
Its application in the drive of machine allows not
only to increase efficiency of cleaning, drying and
sorting of potatoes, but also to increase reliability of
sorting installation that corresponds to the newest
tendencies of development of technology. We have
brought the mathematical model of the offered electric
drive of potato sorting machine, which is implemented
in the environment of object and visual modeling of
Matlab |Simulink|. The mathematical model allows
investigating influence of parameters of the linear induction
electric drive on parameters of oscillatory process
of working body in dynamics. The developed
technique of research and the created experimental
potato sorting machine with the linear induction drive
have confirmed theoretical researches. The main kinematic
sizes of machine and technical parameters of
individual nodes are determined. It is shown, that the
efficiency of inertial transportation can be increased
for 20% in comparison with the classical drive from
the motor of rotation. Results of research will allow to
realize energetically and technologically effective potato
sorting machines with the linear induction drive
This article is devoted to the study of small mammal communities (species composition, daily activity and spatial distribution) in the agrocoenosis. The fields of winter crops that were surrounded by similar fields or by winter crops with meadow vegetation were researched. The Mus musculus became the dominant species in the winter crops agrocoenosis. The R. Sylvaemus living near the border with field-protective forest belts (and 25 meters field around) are subdominant group. Marked single finds Mus musculus in the forest and R. Sylvaemus in the field (at a distance before 50 meters). It is shown that the presence of meadow vegetation increases the species diversity of mice in the agrocoenosis. In the middle of this field a subdominantion group is Microtus arvalis s.l. and Cricetulus migratorius. The both species prefer a neighborhood with meadow vegetation. The method of recapture, followed by labeling with animals, made it possible to fix the movement for a distance of about 400 m. during the night (maximum values were males Mus musculus). The activity of small mammals in the winter crops was timed to coincide with the day-night cycles, with high activity from 01:00 to 04:00 am, and minimum activity after 09:00 hours of the morning before 08:00 pm
The article describes a software interface with the universal cognitive analytical system "Eidos-X++" ensuring the transformation of character, in particular – the numerical series in a form that is directly perceived by this system. As a result, the system can contain 3 statistical and 7 intellectual models of the series, which highlights the relationship between the characters or numbers in these lines. To reflect the relationships between the characters we used the same private and integral data of the automated system of cognitive analysis (ASC-analysis), and in the reflection of reasons-and-effect relationships between events in the real area that has not previously been used in the theory of numbers. The article provides a detailed numerical examples of such studies on the example of the identification of relationships between numbers that represent the decimal digits of the PI number, in the example we use one million digits of the PI number after the decimal point
To determine the mass fraction of linolenic acid in flax
seed oil the authors developed a rapid method based on
the pulse method of nuclear magnetic resonance with
the use of NMR analyzers low resolution. This method
has some significant advantages compared with the
known method on the basis of chromatographic
method for the determination of the mass fraction of
linolenic acid in the oil extracted from the seeds of
flax, namely, does not require additional sample
preparation (extracting oil by solvent), eliminates the
use of toxic chemicals, requires a much lower
investment of time to conduct a single analysis, highly
automated, and eliminates the influence of human
factor on the research results. The method is based on
the revealed correlation between the weighted average
time spin-spin relaxation of protons contained in the
triacylglycerols of the oil of the flax seed, and a mass
fraction of linolenic acid in the seed oil at a
temperature of 23ºc. In article results of research of
influence of temperature on the weighted average time
spin-spin relaxation of protons contained in the flax
seed oil. Installed directly proportional linear
relationship between the temperature of flax seeds and
measured the average time spin-spin relaxation of
protons oil contained in the flax seeds with the correlation coefficient is 0,930, the temperature change
of the sample of seeds at 1 ° C leads to the change of
the coefficient is 0.011 kt. The developed
methodaccuracy in the temperature range from 20 to
26 ºC
Protection of farm animals from diseases remains one of the priority tasks for veterinary practice. A healthy animal is the key to obtaining high sanitary quality of livestock products. Among the veterinary-sanitary and organizational-economic measures carried out for the prevention and control of infectious diseases, disinfection is of particular importance. In the laboratory of veterinary and sanitary expertise of VNIIVSGE-branch of the Federal State Budget Scientific Institution Federal Research Center of the Russian Academy of Medical Sciences, a new composite preparation “Hyponatum BPO” has been developed and is being tested. The studies found that the "Hyponat BPO" has a high disinfecting effect against gram-positive and gram-negative vegetative microflora, located on surfaces of various materials (wood, concrete, tile, stainless steel, plastic), both with the presence of protein protection, and without it
There were presented comparative analysis’ results of
criteria rice quality used in Russian and international
standards. Also there were shown summarized
statistical analysis’ results of rice quality that was
processed in 2013-2016 on rice mill plant at
“Krasnodarzernoprodukt” Company. The purpose of
research was to find factors that had influence on
combining rice bulk effectiveness on specialized
elevator. It was found that diapason of rice moisture
content was quite small. Red rice content was ranging
from 1.08 to 5.10 % with confidence interval of 1.98-
2.56 % that is evidence of small amounts of rice bulks
with extreme high or low red rice content. Broken rice
content varied in the wide range from 3.43 to 9.26 %
with confidence interval from 5.84 to 7.26 % that
shows necessity in length grading procedure applying
for broken kernels removing at the elevator unit.
Grain impurities content exceeded basic norm in 3-4
times that is a sign of low efficiency in the process of
separation. During the treatment of rice bulks
combined at the grain cleaning unit of rice plant
broken rice cereals output varied in wide range from 3
to 9 % during single shift that is seems to be connected
with kernels cracking increasing and rice moisture
decreasing. Moreover, rice bran output also varied in a
wide diapason from 10.2 to 17.0 % that could be
explained by big swing in rice moisture, glassy texture
and cracking of rice grains. According to our research
it was investigated that current rice quality control system that is a base instrument of rice bulks forming
for further processing is not quite efficient and as a
result there should be created and implemented new
methods and technical devices for quick and proper
grain control that could assure stable technological
regimes at different stages of rice treatment process
and that would provide the best quality and the biggest
output of rice cereals
The article shows that for the essential oil industry of
the Russian Federation to solve the problems of import
substitution it is urgent to develop effective technology
to extract fatty oil from the crushed and deprived of
ether by water vapor coriander fruits. The existing
technologies for obtaining fatty oils from deprived of
ether coriander were considered. It is shown, that at
small-scale enterprises it is most advisable to remove
fatty oil by screw pressing. A brief analysis of main
factors affecting the completeness of oil extraction in
screw presses was carried out. The conclusion about
the necessity of preparation of deprived of ether
coriander for extraction with the purpose of increasing
the yield of fatty oil was made. It is shown, that one of
the stages of such preparation is the removal of part of
the shell from deprived of ether coriander, which also
increases the nutritional value of the oilcake.
Fractional composition of deprived of ether coriander
after extraction of essential oil by water vapour and
drying was investigated by sieve analysis method. On
the basis of obtained data, prior to separating the shell
by pneumatic separation, it is recommended to
separate deprived of ether coriander into three
fractions by size – coarse (riddling from the sieve with
the diameter of 1.8 mm), medium (riddling from the
sieve with the diameter of 1 mm) and fine (undersize
from a sieve with a diameter of 1 mm). Component
composition of the coarse fraction of deprived of ether
coriander was studied. It was found, that the content of the shell in this fraction is 36%, which indicates the
possibility of its effective separation by pneumatic
separation
