In the article we consider methodical bases of the analysis of financial and economic activity and a substantiation of rational high-quality structure of crops of winter wheat, as the principal grain culture defining in many respects a gain, financial results of implementation of an agrofirm
It is known, that the voltage deviation from the
nominal value leads to a change in the technical
characteristics of the equipment and may cause a
violation of their working ability, including leading to
an emergency. The article deals with the known
structural diagram of single-phase voltage stabilizers
of AC power, the peculiarities of their work and their
disadvantages. To improve the performance
characteristics of single-phase AC voltage stabilizers,
we have proposed a functional scheme of the
stabilizers performed on transformers,
autotransformers and optosymistors. The article
considers features of the proposed circuit voltage
stabilizers. To stabilize three-phase voltage we have
proposed using a three-phase stabilizer. In this case, to
improve the reliability of the reserve there may be a
single-phase stabilizer, which automatically connects
to the appropriate phase at malfunction of one of the
working electronic voltage stabilizers. To stabilize
three-phase voltage, a stabilizer can be made based on
the three-phase transformer. In comparison with the
use of a single-phase stabilizer in a three-phase
system, the voltage stabilizer will have improved
weight and overall dimensions. To significantly
improve the technical characteristics of voltage
stabilizers, working in the autonomous power supply
systems, it is possible only through the use of modern
mathematical apparatus, allowing to simulate the
physical processes in power circuits of stabilizers in
nominal and emergency modes of operation
At present, the state management of labor protection
in Russia adheres to the goals of harmonizing the
domestic legislation with the best world practices in
this field, eliminating internal contradictions in
legislation and building an active management
system for labor protection provided that a «favorable
climate» for the conduct of business activities is
provided. The regulatory and legal state regulation of
labor protection forms the basis for the development
and implementation of a set of measures to create
conditions for maximum protection of life and health
of workers. The authors consider the modern legal
framework and standards in the field of management
of labor protection in the organization. Reflects the
changes that have occurred in the Russian labor
legislation regarding the employer's duty to create
and maintain a labor protection management system.
The aspects of introduction of the health and safety
management system are considered taking into
account the requirements of the draft international
standard ISO/DIS 45001 «Occupational health and
safety management systems - Requirements with
guidance for use». It is shown that one of the modern
directions of standardization in the field of labor
protection is the development of risk management
and an analysis of foreign practice of legal regulation
of issues in the field of occupational safety. The
article is intended for specialists in documenting
processes carried out implementation, operation and
maintenance of a health and safety system, and on
students of higher education institutions and teaching staff
The problem of establishing of the factorization of
irreducible polynomials with integer coefficients on
prime modules p has been long of interest to
mathematicians. The quadratic and cubic reciprocity
laws solve this problem for quadratic polynomials and
binomials of the form x3-a . More general reciprocity
laws solve the formulated problem for some classes of
polynomials, for example, with Abelian Galois group,
but for polynomials with non-Abelian Galois group,
the problem is far from its complete solution. Our
study shows how using the results of Voronov G.F.,
Hasse H. and Stickelberger L., one can find conditions
that must satisfy prime number p. Gauss received a
similar result for binomial x3-2. Specific examples are
given, for instance, for the polynomial x3-x - I, also
conditions arc formulated for which a quadratic field is
immersed in non-Abelian Galois extension of degree
6. Also, conditions are given under which a
Diophantine equation: а12a22-4a22-4a13a3-
27a32+18a1a2a3=D has a solution for integer values
of D
The study of the productive qualities of crossbred
offspring from different breeding combinations and
identifying the most effective ones providing the
maximum increase in the production of high quality
lamb while reducing its cost is an important problem
and is essential for further development of methods of
creating a new type of precocious meat and wool
sheep. In the Rostov region in the result of the
establishment of populations of meat-wool sheep there
are several groups of animals with different
characteristics and hereditary inclinations. As the base
of the work there is a method of mating and breeding
of sheep of the desired type. The article presents the
results of one of the fragments of a large complex
work in which the possibility of using three-pedigree
hybrids, created with the involvement of potential
salskaya, edilbaevskaya and intense meat-wool breed,
which is severokavkazskaya, to improve productive
quality in the breeding of sheep. We have evaluated
productivity and biological features of hybrids and
proved the economic efficiency of their use in the
production of mutton. We have given the results of the
control slaughter and assessment of qualitative
indicators of the meat of young sheep. The set of
indicators characterizing meat productivity and meat
quality revealed that the superiority of the studied
indicators remained for two - and three-bred cross
cattle. Hybrids have a higher rate of growth and
quality parameters of meat productivity. These options
are simple and complex industrial crossing are
promising and can be implemented and used on the
farms of the zone of breeding Merino sheep. Thus, the
use of crossbreeding gives an opportunity to convert a
flock of sheep in the desired direction quickly. At the
same time, three-pedigree hybrids better combine the
valuable qualities of the used species
In breeding programs, evaluation of initial material is
made on all the stages of developing the variety. Great
difficulties for the breeding process are made by
absence of modern mechanisms for storing, retrieving,
manipulating the relevant data, and using the
information previously obtained for use in solving the
set breeding task. In order to organize the management
of breeding process for development of high-quality
rice varieties, based on the urgency of problem of
intellectual analysis of data, the Database "Rice
Quality" was designed as a set of structured data - the
rice quality characteristics identified in the stages of
the process of developing variety belonging to the
"Rice". In the domain model, the infologic model, a set
of parameters for evaluating rice quality in terms of
out-of-program components is defined. The program is
written in the Microsoft Access database environment
using built-in query building tools, forms, reports. The
structure of the developed tables includes static and
refreshed directories in which the necessary
information is stored, the tables are combined into
one-to-many relationships, while ensuring data
integrity, cascading updates and deletion of fields
Trends in economic growth and the active inclusion of
Russia in the global dynamic processes require a sharp
increase of its competitiveness on the world stage, the
growth of production and consumption culture, which
in its turn sets the task of raising the quality and
education efficiency to a new level, corresponding to
the scale of problems. In the article the ways of
improving the education management system, allowing
not only to identify new approaches, but also to look at
the problems of the industry in a completely different
way are analyzed. The article presented by the authors
is based on the modern conception of education
potential that should be fully used for consolidation of
the society, the preservation of a single socio-cultural
space of the country, overcoming ethnic tensions and
social conflicts on the basis of the priority of individual
rights and equality of national cultures and different
faiths, limit of social inequality. The authors consider
education as one of the largest areas of the world
economy and one of the fastest growing sectors
Tasting and smoking properties of tobacco products
depend on chemical composition of dried tobacco. The
most important are nicotine, carbohydrates, and
proteins. Their content is controlled when new sorts
are bred. In the article data on chemical composition
and their analysis for some hybrids, new and zoned
sorts are presented. Most of studied samples had
medium nicotine content in dried tobacco. Hybrid of
Jubileiniy noviy 142 and Ostrolist 46, sorts: Trapezond
159, 359, 115 and Ostrolist 46 were characterized as
low nicotine tobaccos. Jubileiniy (standard) and
Oktiabrskii were characterized as high nicotine
tobaccos. This indicator depends on rain quantity
during vegetation period. During drought seasons this
indicator is higher. Total soluble carbohydrates content
affects smoke taste. The more water soluble
carbohydrates content the better smoking properties
tobacco has. Unlike nicotine, carbohydrates content
when rainy season increases. Best results were for
Krupnolistniy 9M and Oktiabrskii. Proteins have
negative effect on smoke taste as it becomes bitter and
with smell of burned feathers. Most of studied hybrids
have quite high protein content. For cured tobacco
quality assessment, not total contents of proteins and
carbohydrates are important but their ratio
(carbohydrates/proteins) called Shmuk ratio. Best
results were for Krupnolistniy 9M and Oktiabrskii
The article is devoted to the various elements of the cultivation technology of winter wheat called Antonina with the application of different soil fertility backgrounds, fertilizer norms, and plant protection systems against weeds, pests and diseases. Investigations are carried out in a multivariate stationary experiment: factor ‘A’- soil fertility; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - medium (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil tillage: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. Based on examined researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased, by that, the high quality of the grain is provided
In the soils of rice fields, eluvial gley processes
develop, which are manifested in redistribution of silty
particles along the profile, water-soluble humus,
mobile compounds of iron and phosphorus. Most
intensively, these processes are developed in meadowbog
soils, confined to closed depressions of the plains
plain. Meadow-black soils lying on elevated relief
elements have more favorable physical, physicochemical
and oxidation-reduction properties for
cultivating rice and accompanying crops in crop
rotation. The highest yield of rice is formed on high
checks and higher at 12,4 c/ha than on low ones
