The article presents the results of experimental studies
of band noise generation and multirip woodworking
machines. The studies have shown that saw
woodworking group, as well as metal, are general
patterns in the formation of the spectral composition
that allows to approach the development of practical
recommendations to reduce sound pressure levels in
the work area to the operators of sanitary norms. Of
particular note is the fact that elevated levels of noise
generated by the cutting tool. The effect of changes in
process parameters, in particular, the depth of cut and
feed to levels of noise generated by the tool. For
example, increasing the depth of cut in half leads to an
increase of sound pressure levels at 5.8 dB
(theoretically obtained value is 6 dB), and supplying a
halving of the sound pressure levels reduces by 5 dB.
High enough for engineering purposes convergence of
theoretical and experimental sound pressure levels and
the fact that the calculated values above experimental,
allows the calculation and design of the system to
reduce the noise under consideration in the machine is,
only in service but also in their design
This article focuses on crude oil trade development
between Russian Federation and European Union with
relation to port of Novorossiysk performance for the
period of 2010-2015 taking into consideration
restrictive measures imposed by European Union.
Literature review on the topic of economic sanctions
on Russia and other countries and impact of these
measures on economy of these countries is given in the
article. After analysis of crude oil trade volumes
between Russia and European Union through port of
Novorossiysk it is possible to conclude that decrease in
crude oil trade started two years before the
introduction of restrictive measures. Current values of
international trade indicators can be under significant
influence of sanctions, but the general trend of decline
started before that, and this trend can be connected
with other then political factors. Another conclusion is
the fact that sanctions made an impact on growth of
crude oil turnover, but at the same time this indicator
was negative for almost a decade before, making it
possible to consider the factor of sanctions as
significant, but not decisive
The significance of humus content in soils of the
Krasnodar region is decreased. Losses amount is 0,03-
0,05 % every year. The main means of preservation of
soil fertility is the introduction of such organic fertilizers
as manure. The availability of manure’s use has
decreased significantly in connection with the reduction
of livestock in agricultural organizations of the
Krasnodar region. It causes the necessity of searching
of other ways of replenishing of soil fertility. The challenge
is to ensure a positive balance of organic matter
in soil without application of manure. The reproduction
of the soil fertility can be achieved at the expense
of proper selection of agricultural cultivars in the crop
rotation and provision of optimal structure of sown
areas. The modeling of the structure of sown areas
using the developed economic-mathematical model
allows to determine the optimal composition and the
areas of crops for maximum gross or net income with a
positive balance of humus. It is proposed to use the
general indicators of economic evaluation - gross or
net income, increased (decreased) in the value added
of (left) humus to assess the effectiveness of land use.
The calculations were made on the example of the Ltd
Company “Vorontsovskoe” of Dinskoy District, they
may be adopted for any agricultural organization
Creation of hydraulic fracturing in the physical structure
of the reservoir rock is one important way to improve the
productivity of oil and gas wells. These artificial
channels increase ability of the reservoir rock for
conducting hydrocarbons to the wellbore. In this study a
new approach has been proposed for optimization of
fracture half length in hydraulic fracturing operation.
Also, this new method that is a combination of various
fracturing geometry models has been proposed for
modeling the hydraulic fracturing geometry. We have
shown that there is a reasonable agreement between the
result of pseudo 3D fracture geometry model and the
predicted results from the proposed approach
The article presents research results of a corn harvester
device for corn cobs separation from the stalks,
constructed as a separate picker. Each picker unit
consists of three pairs of flat conveying belts arranged
in parallel to vertical planes, namely an upper pair of
conveying belts, the lower pair of conveying belts and
fixed to corn harvester sweep frame, kinematically is
not connected to other mechanisms and is provided
with electric power with the possibility of adjusting
the width of the aisle and the rapid replacement of the
failed module with a spare unit in the field repairs.
Picker module provides simultaneous rotation of corn
ear on its axis and motion relative to the stem that
reduces corn cobs defect and energy consumption for
separating cob from stalk. The method of calculation
of the basic design parameters of the picker module is
developed
In the article there is a comparative analysis of the
criminal legislation of the countries of the near

During the last century, in the biosphere occur expressed processes of soil degradation due to anthropogenic influence, which seriously change of top layer of soil. The agricultural landscape is allocated of noticeable accumulation of various wastes at expense of growing of food crops and grazing of farm animals, as well as due to mineral wastes generated in process production of building materials and fertilizers from natural raw. According to physical and chemical characteristics of wastes of plant origin and natural-raw wastes constitute a non-toxic highly dispersed connection with an admixture of different undecomposed organic and mineral substances. Specificity of physical state is determined there of high dispersion, which is represented by system particles of colloidal substances distributed in various environments. Colloids of natural-raw wastes are characterized by a low rate of diffusion; do not penetrate finely porous membrane of cell structures, different very nonequilibrium insolubility and specific chemical composition. For example, phosphogypsum is characterized by high concentration of sulfur and calcium, and trace amounts of entire table of D.I. Mendeleev. Organic wastes are made by variety of chemical compounds and high concentration of carbohydrates, proteins, fats and other organic substances
The article describes the national education paradigm,
which considers the process of learning-education as
an important mechanism contributing to the formation
of students’ personality according to their abilities and
needs. The problem of a modern teacher consisting in
optimization of educational process based on the
student’s individual needs is considered. Etymological
analysis of the term "optimization, which allows
defining its understanding is produced. The basic
criteria of optimality derived by different authors are
described. The article also examines such psychology
section as an educational psychology. It is said about
the structure of modern Russian education system,
which includes four interrelated and interdependent
elements. The article draws conclusions about the
necessity of designing individual educational trajectory
to satisfy the specific individual educational needs.
The basic principles of the Russian educational system
and in accordance with it, the educational process in
terms of constructing the optimization strategy are
considered
The work was carried out in the scientific-research
laboratory of the chair of Biotechnology, Biochemistry
and Biophysics of Kuban SAU, the aim of which is the
search of optimal conditions of obtaining the
hydrolyzates of lactic acid bacteria by thermoacid and
enzymatic ways. The pure cultures of microflora of
gastrointestinal tract of quails − Lactobacillus agilis,
Lactobacillus intermedius and Lactobacillus salivarius
were the object of researches. Under conducting the
thermal acid hydrolysis there were used the same
correlations of bacterial mass and water as well as
procedures of clearing of hydrolyzates. The variable
conditions were рН, temperature and time of hydrolysis.
When carrying out the enzymatic hydrolysis in this
study there was used the enzyme from the group of
muramidase lysozyme. The amount of enzymes and
time of carried out hydrolysis were the variable
conditions under obtaining the enzymatic
hydrolyzates. In the process of researches there were
studied: qualitative content of total protein, peptides
with М.м. < 1500, protein and peptides with M.m. >
1500, aminoacids and as well as GMDP
(glucosaminilmuramilpentapeptide). On the basis of
carried out experiments there was stated that according
to all components of biologically active substances the
thermal acid way is more effective than enzymatic. The maximum accumulation of BAA in hydrolyzates
by different ways was revealed at destruction of cells
Lb. intermedius. Content of GMDP in thermal acid
hydrolyzate was higher than in enzymatic on
0,028 g/100 ml (51,8 %)
The article touches the problem of studying the procedure
of granting housing to refugees and IDPs (internally
displaced persons) as well as their family members. The
procedure of granting housing to refugees and IDPs is a
very important process, being one of the general stages of
the modern border policy of Russian Federation. The
Standards of Housing Code and Code of Federal
Regulations, which secure legal status of these categories
of citizens, are analyzed In this article. The authors
analyze criteria of giving the refugee or IDP status to a
citizen, the procedure and conditions of providing
housing to these categories of citizens. Based on the
studies, the revision of the Standards of Housing Code,
particularly, the expansion and supplement to the notion
«accommodation» is offered, also it is offered to combine
the general regulations on the procedure of providing
accommodations to the refugees and IPDs. It is also
substantiated in the article that there is need to amend the
notion of specialized housing fond. The authors consider
reasonable to clarify what are the other accommodations
of different status that can be provided to refugees, IDPs,
and their family members. The proposed changes in
housing legislation will let us simplify and adjust the
mechanism for implementing the housing regulations in
legal relationships in providing housing for refugees,
internally displaced persons and their families
