Here we present a brief survey of noise effects on
human’s organism in production conditions, including
noise effects on operators of machines and technical
devices. It is well known, that any biological organism
exists in balance with its environment. However, noise
effects being stress factors knock the operator of
machines and technical devices out of the working
rhythm and cause different kinds of health disorders
such as blood pressure increase, fatigue, disorders of
the central nervous system and gastrointestinal tract
and the like. All this may lead to accident situations,
reduction of labor productivity and quality of work.
Frequently health disorders start with hearing
impairment which leads to disorientation in the threedimension
space and malfunction. It is because the
hearing apparatus as biological system provides the
organism with sensory information and ensures selfpreservation.
In the noise conditions, these
characteristics are conflict: on one hand, the hearing
organ should possess high enabling capability to
receive positive signals, and on the other hand, in
order to adapt to the sound hearing and sensitivity will
decrease. The duration of noise exposure and the
number of years spent under influence of the noise are
also of great importance. Thus, it is obvious that
control of the noise and prevention of harmful effects
of the noise on machine operators are important
components of production process in the agrarian
sector
Disc tools are designed for the surface treatment of the
soil, as well as for loosening and preparing the soil for
planting, weed control and grinding residue, for
seedbed preparation without preliminary plowing in
the system of minimum tillage technology and after
thick stem row crops harvesting. It implements a disk
type implements include a disc mounted on the
individual rack. Classical instruments of this type are
made with a rigid stand mounting the cutter body to
the frame. In the classical working body attachment
scheme has a number of disadvantages. One of them is
the lack of a safety element. The proposed version of
the working body of the fastening using a spring strut
has the following advantages. When zooming in on the
disc obstacles (dense soil, bump, pit, stone), flexible
disk drives backward, up, down or to the side (left,
right) by the spring property (elasticity) of the curved
rack. This design reduces the shock load on the
bearing assembly, wherein the disc is returned to the
original position by passing earth and crop residues
without blockage. The purpose of structural changes
was to reduce the energy intensity of the surface
treatment process of the soil while improving
reliability
Early-ripening white cabbage has a special place
among the vegetables cultivated in Kuban region. It
opens the pipeline of vegetables from the open
ground and is supplied to other regions at a time
when shortage of vegetables of domestic production
is felt the most. Modern producer requirements to
domestic hybrids are the highest - product quality,
uniformity and productivity should not concede to
foreign analogues. Ways to improve the quality of
early ripening hybrids: development of lines based on
modern foreign hybrids, high uniformity of lines by
morphological and economic traits. Development of
male sterile lines and dihaploid lines in culture in
vitro can more successfully solve the problem of
quality of early ripening hybrids. The use of the
above methods and approaches helped develop series
of inbred lines - gene sources for complex agronomic
traits. On the vase of obtained lines promising earlyripening
hybrids were developed. One of the hybrids,
Ritsa F1, entered the State register of breeding
achievements. Advantages of the hybrid: earliness,
uniformity and high marketability of heads, high
productivity. According to results of contest trial new
hybrid Milana F1 is passed for State trial, this hybrid
has high productivity potential for growing in sale
cropping. Both hybrids were produced with the
participation of male sterile line Dt46f, resistant to
fusarium. High quality seeds of these hybrids were
produced in a greenhouse in direct crop for a wide
industrial and environmental testing
The article proposes a solution to one of the problems
of small business, which is creation of a part of the
software of management of information system
efficiency for small processing enterprises of AIC.
The fact is, that currently, there are almost no
information systems to support small business. All
known information systems have approximately the
same list of automated functions, covering the
accounting phase, and sometimes phase of analysis.
Practically, not affected by the evaluation function of
the economic situation, prediction, planning and
regulation. The proposed mathematical model has
been developed on the basis of the creation of
streaming schemes of one-product processing
enterprises of agroindustrial complex and
mathematical description of the proceeding financial

The struggle against soil erosion and the restoration of disturbed lands is a pressing issue for the regions of the North Caucasus and southern Russia. This problem is also acute in Kabardino-Balkaria, where more than 30% of agricultural and coastal lands suffer from water, anthropogenic and man-made erosion.
Existing methods need to be improved and adapted to natural and local conditions. The aim of the work was to develop more efficient methods for the accelerated recovery of eroded and disturbed areas of land with the use of biopositive products and fastenings from local materials. Several technological solutions have been developed for the protection and restoration of land plots of agricultural and recreational zones located on slopes and coastal zones that have been eroded and disturbed by economic activity. All of these technical solutions are investigated and brought to the level of inventions and utility models. According to the results of the research conducted for the mountain and foothill areas of eroded lands, new methods are proposed based on the use of environmental protection technologies and restoration of damaged land. The introduction of these methods increase the effectiveness of anti-erosion measures and reduce the material costs of their implementation
The article is devoted to the development of a compressor
type ozonator. It describes the design of a
high-productivity compressor ozone generator, which
can be used for industrial decontamination of mixed
feeds, water, milk, and in the system of presowing
treatment of seeds. This construction allows generating
ozone with high concentration to 5 g/m3 at high feed
air or oxygen from the compressor station (up to 2000
l/min). The article describes the design of the basic
elements of tubular ozone generator, examines the
factors influencing the productivity of the ozonator.
The proposed mathematical model allows calculating
the productivity of the ozonator when considering multiple
influencing factors. These factors take into account:
the parameters of supply voltage, such as the
magnitude and frequency of the supply voltage; the
configuration and geometrical parameters of electrodes
such as, the area of the electrodes, the configuration of
the surface of the electrodes and distance between
electrodes; parameters dielectric barrier; and the transported
gas parameters such as volume, temperature,
pressure and composition. Special attention is paid to
the design of the electrodes made of woven wire mesh
with mesh sizes from 1.5×1.5 to 2.0×2.0 mm. It is noted,
that such electrodes allow obtaining the maximum
productivity of an ozonator, and they do not lead to
overheating of the dielectric barrier, and do not output
down the generator. In the same way, the article presents
the results of the mathematical modeling
of ozone generator productivity while changing
various factors
The work was done based on the collection of the
natural flora of the Yakut Botanical Garden. The
object of research was the seeds of 22 species of the
family Ranunculaceae. It is known that the seeds of
many buttercup characterized morphophysiological
tranquility associated with hypoplasia of the fetus
(Nikolaeva, 1988; 1999), due to what delayed the
germination of their seeds. Laboratory germination of
seeds of the studied species varies from 0 to 100%.
Among them, we have not found the kinds seeds
which have explosive or fast germination (1 type of
seed germination). The germination of the studied
seeds states ranging from 6-7 days or more. The
studied seeds were evenly distributed between 2 (12
species), and 3 types of seed germination (10 species).
Type 2 is characterized by slow germination, type 3 -
poor germination or lack of it
Russia begins to work on the formation and
implementation of recycling systems for

Nigeria has the largest oil sands and bitumen resources
in Africa and is one of the main leading countries in the
world from the point of view of its significant potential
heavy oil deposits. Research of geological and physicochemical
properties confirmed that the Nigerian bitumen
is an important energy source and an alternative source
of hydrocarbon feedstock for the petrochemical industry.
Nigeria imports black oil for the petrochemical industry
and its heavy oil can act in place of this black oil. In
addition, researchers have successfully established the
possibility of producing electrical energy from this
heavy oil. Tar sands and bitumen are able to help
improve the economy of Nigeria
Nicotiana tabacum and rustica are facultative self-pollinated plants, therefore, because of pollination peculiarities, specific methods are applicable to growing seeds of this plants. Researches on mass, individual and family, recurrent methods of seeds selection for productivity and sowing properties are carried in the institute for revealing most efficient methods of getting seeds. Seeds growing system for Nicotiana tabacum and rustica is a part of general seeds growing system for all agricultural plants and consists of breeding, testing new sorts, mass reproduction of seeds with retained biological and productivity properties, seeds harvesting and controlling their sort and sowing properties. Primary growing of nicotiana tabacum and rustica seeds is carried by individual and family or recurrent selection and further testing of chosen plants, distinctive for this sort, on economically valuable and biological properties. Peculiarities of each zoned sort are kept by retaining its primary genome with constant selection of highly productive genotypes, specific for this sort. Well-organized seed growing system leads to sort potential revealing. Biotype composition of sort is obviously changing in a few years, so primary seeds growing system should be constantly improved
