In order to ensure import substitution and threshold
values of meat production, it is necessary to stabilize
the livestock of animals and introduce intensive
technologies. In conditions of arid steppes, the animals
of Kalmyk, Hereford and Aberdeen-Angus breeds are
best suited to stall-pasture technology. Before weaning
from mothers at 7-8 months of age, their offspring is
grown without additional feeding, just mothers’ milk.
Therefore, the growth rate of suckling young animals
rarely exceeds 850 grams of daily growth, while the
live weight reaches 400-450 kilograms at the age of 18
months, with some advantage in favor of the young
generation of Hereford breed. Using the intensive 9-
months growing at the fattening complex with feeding
from the self-feeders ensured the average daily gain in
the Kalmyk bull-calves at the level of 1398 grams, and
for the Aberdeen-Angus and Hereford breeds the
growth is 1533 grams. The highest growth energy, live
weight (661 kilograms), was with Hereford bulls.
From bulls of the native Kalmyk breed with intensive
technology of growing, a heavy body weight increase
of 331 kilograms at 18 months of age was obtained.
All tested samples of meat according to
microbiological indicators comply with the
requirements of the Technical Regulations

The article begins with the letter of the chief
engineer of chemical plant near Moscow. He
requests to analyze of data by means of modern
statistical methods and give an opinion on the
presence (or absence) of the relationship between
the two methods of determining the viscosity of the
mastic. For each of the batches of mastic It was
presented two numbers - the viscosity measurement
results of the two methods. These numbers form two
paired samples. We want to install, give whether
two specific methods similar results. The true values
of viscosity in different batches are not equal. Their
difference is not allows us to combine the results of
the first measurement method in first sample, the
results of the second method - in the second sample,
as we can do in the case of testing the homogeneity
of two independent samples. For solutions to this
problem we discuss four statistical criterions, based
on a study of the differences between corresponding
values in two paired samples. We test the hypothesis
of equality 0 of median of these differences (sign
test) and of equality 0 of the mathematical
expectation of these differences. Hypothesis of
testing of equality of the distribution functions of
two paired samples is reduced to the hypothesis of
symmetry of the distribution function of these
differences with respect to 0. In the alternative of the
shift is proposed to use the Wilcoxon signed rank
criterion. In the total alternative is proposed to use
criterion of the omega-square type which is
developed by the author of this article
The article deals with studying the ways of optimizing
the amount of chemical additives in the wood-concrete
material, i.e. arbolite, which contains foamed
polystyrene gravel aggregate. To make arbolite
honeycombed structure more conglomerated a nonreactive
aggregate, i.e. hogged chips, has been partially
replaced with foamed polystyrene gravel aggregate
which has a mean particle size equal to a concrete
pocket size. The article also deals with various
additives to be used, taking into account the nonreactive
aggregate type and its quality, the composite
density and its reinforcement level. All chemical
additives have been chosen to make the initial material
more porous, to produce a film covering the aggregate
surface and to speed up the process of concrete
hardening. To solve to above problems a series of
experiments was carried out, the latter studied various
combinations of factors changing at certain levels. The
results of studying the foamed polystyrene gravel
aggregate influence on the arbolite structure and its
characteristics were used to make a choice of the
arbolite composition. The main criterion of the optimal
amount of chemical additives has been considered the
arbolite strength. The experimental data processing has
resulted in the finite regression model which describes
the chemical additive amount influence on the arbolite
strength. The tables in the article show the levels of
technological factors varying and the matrix of
planning the experiments to be carried out in order to
optimize the chemical additive amount. As a result of
the research accomplished the optimal amount of
chemical additives has been determined which enables
to produce the arbolite with some foamed polystyrene
gravel aggregate in its composition
To develop the novel herbicide antidotes for the

Decision-making requires a thorough analysis of the
external environment in which the economic system
operates. Anti-Russian economic sanctions is
significantly destabilized external environment that
has complicated the task of making decisions on
management of the enterprise. This study analyzes
the problem of decision making under conditions of
the uncertainty caused by the anti-Russian sanctions,
the conclusion about the limited decision-making
methods based on game theory. The most effective
are management practices supported by information
systems. The article analyzes the current information
technology of managing a company made by
different developers who have already installed their
software products on objects, which are strategic for
the Russian economy. In terms of economic
sanctions, such a situation creates a threat to the
economic security of the country. Based on domestic
developments, it is proposed to construct an
information model of the enterprise, which will
reduce the risks and increase the quality of
managerial decisions. The work presents a structural
scheme of the information model and defines its
objectives and characteristics

Every year pirates attack hundreds of ships and
thousands of sailors. So, by the end of 2014 violent
actions of the pirates have undergone more than 5,000
sailors. In 2015, the pirates attacked 246 vessels they
had captured 15 ships and 271 of a sailor. While one
sailor was killed and 14 wounded. The economic
damage from pirates was tens of billions of dollars.
For these reasons, the fight against piracy and
Maritime terrorism becomes a major concern of the
world community. In today's complex for a variety of
reasons conditions, convoy of transport ships warships
for the passage of areas endangered by pirates is
considered the most effective and reliable means of
coping with the corsairs of the XXI century,
precluding the capture of the ship and its crew. At the
same time, the training of personnel to solve specific
problems impeding reoperate requires performing the
whole complex of preparatory measures, including
psychological and physical training of sailors for the
upcoming action of a dangerous nature. The article
reveals the content of the methodology of forming and
evaluating the readiness of military seamen to counter
pirates and terrorists at sea represents a set of methods,
forms and means of pedagogical influence with the
purpose of providing soldiers pedagogical assistance in
the development of military-professional activities,
standards of behavior and support in preparation for
military service in the areas endangered by pirates; the
development of military-professional competence; the
full realization of personal potential of specialist fleet
The analysis and assessment of risk at the macrolevel
in this context is understood as assessment of extent
of influence of the external environment (macro
environment) on activity of the integrated production
system. In the article the model and the technique of
calculation of an integrated indicator of risk of an
adverse effect of the external environment of the
agro-industrial integrated production system is
offered. All stages of creation of the model which
include representation of basic risk factors of
macrolevel in the form of linguistic variables are
described, each of basic risk factors is a compound
linguistic variable. For obtaining total value of a
basic factor the matrix scheme of aggregation of
compound factors to basic level is used. The
equation of model of an integrated indicator of risk
of an adverse effect of the external environment on
the integrated production system is presented. The
principle of recognition and interpretation of result
on the basis of standard fuzzy 01-classificators is
shown. Also in this article the interrelation of an
integrated indicator with the choice of the strategy of
