The species composition of carabidae in area was classified according to the Sharova’s system of living form and the detailed analyze has been done in this work
In rapidly changing conditions of the modern world,
analysts and decision makers are in need to use new
formal means of analysis and evaluation of alternatives
problems. This work is dedicated to the development
of such tools. The article presents a detailed analysis
and technical and economic characteristics of the
subject area - the financial market and its specific
components - the value of a time series of gold, silver,
palladium, platinum, and two kinds of exchange rates:
EUR / RUB, USD / RUB. The authors have proposed
a 5-criteria economic-mathematical model of the main
components of the ranking of the financial market. The
authors argue the impossibility of using a single
integrated set of criteria for the replacement of the
criteria or the use of criteria convolution procedures as
the standard procedure of solving the problem of
multi-criteria optimization. It demonstrates that such
criteria as criteria for "risk" must be considered as an
estimate of the degree of deviation from the expected
value of the possible values of this criterion. The
practical significance of the results is determined by
the fact that the main points, conclusions,
recommendations, models and methods can be used in
order to improve the management and planning of
development strategies of banking systems, trading
platforms, as well as by developers of information and
analytical systems to support management decisionmaking
At the nodes of the various machines, we use plain bimetal bearings: a steel base - antifriction cladding layer. Bimetal bearings have increased performance. One of the ways of making such bearings is the way of centrifugal bimetallization with heating of the independent electric arc. An important requirement of this technology is a uniform heating of the workpiece along the entire length until the formation of a continuous layer of the molten cladding material. The process of bimetallization require temperature control, since within the movement of the electric arc, low heat or high heat are possible due to heat dissipation from the ends of the workpiece in the installation and from the outer surface of the workpiece to the environment. A viable option the temperature control of the heat process of bimetallization for industrial conditions is to control the temperature of the outer surface of the steel base. It is necessary to solve the heat problem of the relationship between the temperature on the surface of the workpiece with the temperature on the boundary layers. For this purpose the numerical solution of the mathematical model of the thermal process, which includes the heat transmitting equation of Fourier and heat transfer at the ends of the sleeve according to Newton's law. The equivalent coefficients of heat transfer are obtained based on calculated and experimental thermograms. This is a time-consuming work. To minimize the time of fixing the boundary value problem of the thermal process of bimetallization, in this work we present the preliminary modeling based on the analytical solution of the thermal task of bi-metallization
The industrial safety on cereal production is currently
important due to the severity of the consequences of
accidents occurring to them. It should be noted that,
despite the considerable efforts of recent years,
awareness-raising and supervisory plan towards
preventing their occurrence, the lack of attention of
organizations operating hazardous production facilities
to comply with the relevant standards and
requirements allows us to characterize the recent
situation in this area quite difficult, as evidenced by
statistics. In this article it is clearly illustrated the
qualitative and quantitative expression of such an
approach in practice. The conceptual framework is
disclosed in the light of efforts to carry out industrial
safety examination in the conformity assessment of
hazardous industrial facilities according to industrial
safety requirements in the Russian Federation. The
basic methods and technical means used for the
prevention of accidents at hazardous production
facilities of storage and processing of plant raw
materials provide an overview of domestic and foreign
producers. The item-description of the system of
protection of buildings and facilities of hazardous
production facilities is given taking into account the
industry specifics. There are specified the key factors
meeting modern technical requirements, cost-based
position of enterprises, ensuring conditions for safe
operation of the storage and processing of plant raw
materials
The article presents the results of the analytical
research of the movement of components of forages in
screw drums on the example of relative reels of
Rts7.1.A and Rts5.1a having the next feature: on the
perimeter, we have obviously expressed conditionally
cylindrical screw lines formed. The carried-out
analysis of the movement of particles of components
of forages in relative screw drums and the executed
review of mathematical models in relation to the
