In this work, we develop a model describing the
propagation and branching of a streamer in a conducting
medium in external electric field. To describe the
contribution of the conductivity currents, we modified
the standard electrostatic equation taking into account
the vortex component of the electric field. As a result of
this generalization, the streamer model is formulated in
the form of nonlinear equations of parabolic type. In the
framework of the proposed model, the problem of the
propagation of a streamer in the form of a traveling wave
is considered, which leads to the emergence of SaffmanTaylor
streamers. For streamers of this type, the
branching problem is formulated, which has a unique
solution. The dependence of the branch point on the
parameters of the problem-the speed of the streamer, the
diffusion coefficient of the electrons and the strength of
the external electric field, is found. The branching
mechanism of the streamer head by dividing it into two
parts has been well studied and several alternative
models have been formulated for its description. The
novelty of the problem in question is that the streamer
splits into two three-dimensional channels that are
symmetric with respect to the given plane. Numerical
experiments also revealed the mechanism of branching
of the streamer in the cathode region, connected with the
separation of the main channel into several lateral
branches. It is noted, that in nature both branching
mechanisms are realized, whereas in theory the
instability of the surface of the streamer head is
investigated
This article reviews interpretative position of
prominent German philosopher and psychologist Erich
Fromm on mass men destructiveness analysis. As a
rule, to reach a goal of well-balanced embedding into
consumer society structure, mass man passes through
stages of deindividualization and common averaging
by accepting prescribed general postulates of society’s
authorities. Nevertheless, own personality refusal and
‘rules of the game’ following adduct to moral
degradation, which causes destructiveness
phenomenon. Out of socio-political regimen,
destructiveness appears in attempts of ‘freedom
escape’ by any possible means. Totalitarian regimen
ideologically steers mass men through total subjection
to defined life track by agreement of individuality
sacrifice. Democratically-minded consumer societies
require deindividualization and partly rights pinching
in exchange of status consumption system integration.
Any patterns of counteraction to these system
processes are commenced by personal activity
manifestation and motivation in reaching own goals.
However, conformist majority is meant to live
according to ideologically defined society rules
Industrial region passport is a comprehensive
information tool for forming the sustainable consistent
conception about the industrial economic sector of
administrative territorial unit for third-party users. This
content is being formed by taking into account
following elements: maximum completeness of the
provided information, minimization of the facts
distortion and empirical data; simplicity and clarity of
the data provided in an accessible form with
informative and illustrative material; classifier by
potential users’ interests’ availability. In the article,
exemplary structure of the industrial passport
according to the developed requirements is proposed.
In addition, the formation of a working group in the
structure of economy sector government bodies is
proposed; its tasks include organization and carrying
out the relevant works. The article describes a
proposed phased-gradualist procedure for creating the
industrial passport of the area or district. The
developed industrial passport can be used: in the
investors attraction activities to the regions with an
industrial orientation of the economy; within industrial
exhibitions, convents and conferences conducting; as a
tool for operational diagnosing a certain industrial
potential; as a tool for information accumulating for
comparative analysis of the industrial sector
functioning in the territorial and temporal dimension;
among with other complex tools for the area
investment attractiveness increase; as a reasoning element
for project platforms necessary for the cluster
forms of industrial production organization
For the research period (2003-2016), 57 pest species
and 46 pathogens were recorded on stone and
pomaceous fruits in humid Russian subtropics,
among which the representatives of the order
Lepidoptera and the division Ascomycota
predominate. The greatest number of the species was
recorded on the apple tree - 35 pests and 25
pathogens, the smallest - on cherry and sweet cherry
trees (13 and 10, respectively). 43,7 per cent of the
species are polyphages, while the relative abundance
of monophages among fungi is higher than among
arthropods. The species with activity in the summer
are prevalent. A group of species that are harmful in
humid subtropical environments all year round (11
species of phytophages and 19 pathogens) was
identified. Analyzing the changes in the species
composition of the complex through the time, we can
speak about the relative stability of the dominant
species. The group of the typical dominant species of
pests for almost a century has included Grapholita
molesta Busck., G. funebrana Tr., Cydia pomonella
L., Taphrina deformans (Berk.) Tul., Stigmina
carpophila (Lév.) M.B. Ellis, Monilinia laxa (Aderh.
et Ruhland) Honey, M. fructigena Honey,
Podosphaera leucotricha (Ellis & Everh.) E.S.
Salmon, Venturia carpophila E.E. Fisher and pear
V. pyrina Aderh. Eriosoma lanigerum Hausm.,
Scolytus mali Bechst. and Tranzschelia prunispinosae
(Pers.) Dietel are currently dropped out
from the group of the dominants; Halyomorpha halys
Stål, which is a new pest for Russia, was added.
Groups of the species with sharp fluctuations in
abundance or frequently encountered were
distinguished
This work presents main kinds of colourants and methods of painting wood particles. Based on wood structure analysis, it was revealed that hard wood, possessing tracheides and vessels as conducting elements, have the optimal capacity for coloration, in comparison with coniferous trees. A methodology was developed of cloning wooden particles, in the form of chips, with forced immersion in order to obtain established parameters of saturation and brightness. The experiments were conducted with chips of 15-50 mm long, 5-20 mm wide and 3-7 mm thick. The composition of colouring agent included water, acetic acid, and water-emulsion colourants of different types and colours (№1 – colour code (red, yellow, and brown) №2 – colorant (lilac and orange) and №3 – paint). Experience has shown the needed concentration of liquors and mass percentage of compounding ingredients. The research was undertaken to study concentration dependence on the time of allowance and saturation. In consequence of colouring experimental batches of chips, a painting saturation of 4-9 points was obtained at the allowance of 120 and 140 seconds. Dependence of brightness from solubility was determined, with high correlation between given parameters on Pearson Criteria (more than 0.9). Comparative analysis made it possible to discover that the better colouring of particles is created with the red paint. In this case maximum colouring effect is achieved with liquor of water-emulsion paint. Subsequent to the experimental results, a design of installation for colouring wooden particles was developed and patented
The anthropologism is traditionally considered the
main feature of Russian philosophy. The article
reviews some anthropological ideas that have received
natural development in such direction of thought as
philosophical realism in the 2nd part of XIX century.
Philosophical realism is positioned as a trend that has
emerged within the mainstream of the basic traditions
of Russian philosophy. It is noted that this direction is
defined as an independent, in the wake of the
strengthening of Russian science as a new cognitive
paradigm. Substantively, philosophical realism is
presented with the theories and concepts of the natural
sciences developed in the 2nd part of XIX century.
The realistic outlook, ripening in the Science
environment, not only supported the anthropological
tradition of Russian thought but put them on a
scientific basis. It was dominated by the view that only
by using scientific methods can reveal the objective
laws of coexistence between man, nature and society.
The article deals with the anthropological theories of
Russian thinkers such as A.N. Radishchev,
A.I. Galich, N.G. Chernyshevsky. The anaysis shows
that realistic outlook in the natural sciences in the area
of human theory relies on the principles of integrity,
panmoralizm, cosmism. The conclusion is that the
philosophical concepts by realistic scientists are out of
attention of modern scholars. In the meantime, the
study of these theories can make a significant
contribution to the practical experience of
comprehension of reality, as well as help to discover
new sides of the domestic, national philosophy
The work considers the method of sketches or visual
notes which plays a basic role in the development of
training courses. We have focused on the method of
sketches as "a variety of visual notes, consisting of
handwritten text, drawings, diagrams, figurative
elements". For immersion of the student into the
subject area or object of study, the visualization of the
material is an effective technique of knowledge.
Cognitive function is manifested through the ability to
know the object by the image and the further formation
of ideas about the structure of the material being
studied. It is noted, that visual methods and
techniques are especially effective in the first stage of
researches. Then, there is the collection of material,
knowledge of the research object. Types of pumpkins
were the object of research, presented the works of
artists of different periods. The collection consists of
120 images that were collected in the period from 2012
to 2016. In the work, the attempt is made using the
method of visual notes and visual techniques to build
images of plants pumpkins which displayed in art
works of different centuries and interpreted as "a kind
of door" through which we can enter in our area
(introduction history of culture, archaeogenetic,
developmental biology, the history of selection)
In the article, it is told about need of the correct and rational use of fixed assets with system of the organization of accounting in branch of a structure of power objects. Operational stages of fixed assets at an initial stage of construction are shown. The main questions and problems of rational use of fixed assets are investigated. Fixed assets in the course of production carry out a role of means of labor, which are used by the person as the conductor of his impact on objects of the labor for the purpose of their adaptation to satisfaction of the requirements. Fixed assets make a basis of material and technical resources of the organization, define her technological level, the range, quantity and quality of products, the performed works and the rendered services. Fixed assets via the economic mechanism of depreciation and costs of their repair participate in formation of prime cost of goods (works, services) and financial result of activity of the organization. The facts of economic life on leaving of fixed assets exert considerable impact on financial result as well. Therefore, for ensuring reliability of information, which is contained in accounting reports, the organizations have to keep account of the facts of economic life with fixed assets in strict accordance with normative documents
In the diagnosis of subclinical, serous and catarral mastitis of cows a wide range of microorganisms has been isolated, including the genera Streptococcus (Str. disgalactiae, Str. agalactiae, Str. pyogenes), Staphylococcus (St. aureus, St. epidermidis) и E. coli. When treating cows with mastitis with argovit, the average duration of treatment for animals was2.9 +0.1, 3.3 + 0.3, 4.1 +0,2 days, which is 1.6, 1.9, 1.8 times less compared with the drug spectromast in the control group. The effect of argovit containing silver nanoparticles on antibiotic sensitivity in selected microflora in the treatment of subclinical, serous and catarrhal mastitis of cows was studied. Studies conducted to determine the antibiotic sensitivity of isolated microorganisms after the treatment of mastitis of cows showed the dependence of the results, both on the drug used and on the clinical form of the disease. It has been established that the use of spectromast causes a pronounced decrease in19 (76%) preparations with subclinical, 24 (96%) serous and 23 (92%) catarrhal mastitis. It was also noted that with the development of the pathological process, an increase in the appearance of previously absent resistance to antibacterial drugs was observed with subclinical6 (24%), serous 7 (28%), catarrhal 8 (32%) mastitis of the cows. While using argovit, an increase in antibiotic sensitivity to 21 drugs (84%) in subclinical, 24(96%) in serous and 23 (92%) catarrhal mastitis was revealed. In the treatment of subclinical mastitis in the experimental group, a slight decrease was observed for 4 (16%) drugs
The article reflects information characterizing the significance of mastitis and endometritis in the indicator of premature disposal of cows from herds of large farms in the western regions of the Krasnodar region: an average of 30% of the total culling of cows. The effectiveness of veterinary measures in Pravoberezhny JSC of the Temryuk district for mastitis and endometritis in cows was assessed: 81-95%; fertilization index value ‒ 1.8; the duration of the service period exceeds the requirements by 20 days. The studies the nature of the influence of the drugs called Sepranol and Uteroton on the calving process and the occurrence of postpartum complications in cows from the herd, which was formed with violation of breeding principles. The use of the drugs Uteroton and Sepranol contributed to a 50% decrease in the calving index in calving cows by 50% compared with the results of the combined use of estrophan and oxytocin. The use of Uteroton reduced the damage from the lack of milk by 87880 rubles, and the use of Sepranol - by 171164 rubles. We have given practical recommendation on the use of Uteroton and Sepranol for veterinary effects on the body of cows in the early postpartum period in order to reduce the occurrence of complications
