SLF/VLF electric radiation emitted by rock samples due to the slow-growing pressure and the shock impact was studied. Rock samples’ specific electrical resistance change due to the shock impact is examined
The article presents the experimental results of the
study of the concentration dependence of the electrical
conductivity of heterogeneous ion-exchange
membranes that are in contact with solutions of weak
electrolytes - carboxylic acids. It is shown that in this
case the membrane conductivity is higher than the
conductivity of the solution, wherein the conductivity
of cation exchange membranes substantially greater
(by an order of magnitude) than the conductivity of
anion exchange membranes. This fact must be
considered when designing the actual electrodialysis
processes of processing solutions containing organic
ions. The work identified the need to develop modern
ideas about transport and the structural organization of
ion-exchange materials, to describe the structure of the
ion-exchange membranes that are in contact with weak
electrolytes solutions
The article deals with the study of vehicles impact on
the environment, since one of the main causes of air
pollution are cars with internal combustion engines.
One of the most important measures in the fight for
clean air is the creation of an environmentally
friendly transport. From this point of view, the most
promising is the electric car, as the only solution to
the problem of atmospheric pollution. In this article,
the history of the development of modern electric
vehicles, the advantages and disadvantages of their
design, as well as the possibility of introducing
electric vehicles into everyday life are considered.
After the analysis, it was concluded that, in spite of
the obvious advantages and the huge path that electro
mobiles went through in their development,
humanity is still not ready to refuse from cars with
internal combustion engines, opting for electric
vehicles
Wave solutions of Einstein's equations in the sixdimensional
space-time with metric signature (+, +, +, -, -, -) have been found. It is shown that solutions of this type can be used to model the structure of the electric charge
The article gives the results of elaboration of the express method to identify high olein sunflower-seed oils based on nuclear-magnetic relaxation
The article contains the mathematical model of cooling shaving boards, which was made with small-toxic resins; it make possible to determine the length of the cooling boards on given temperature in every moment. Suggested the equipment for cooling shaving boards, which will make it possible very effectively cool the boards
The article considers the new method for recovery of P. arbelaeziion intact material on the basis of grafting into endogenous pathogens resistant Passiflora species in vivo. The influence of the explants origin depending on the stock of intact plants on the development of regenerated P. arbelaezii under in vitro condition is examined
The article deals with the possibility of expanding of agricultural tools in risk management based on commodity financial instruments and weather derivatives. On the basis of summarizing the research results of domestic and foreign scholars and creative interpretation of the results the authors supplemented and refined definition of the category of "risk" and "risk of agricultural production” is obtained. The article supplements classification of risk in agricultural production and circulation of agricultural products, considers a proven techniques and methods of agricultural risk management, discusses the current trends of the global and domestic market of derivatives, gives a market segmentation by type of derivative instruments and the characteristics of the underlying assets, analyzes the reasons for the low level of development of derivatives markets at the meso level using the example of the Krasnodar Region, describes the potential derivatives in addressing management of agricultural risks on the basis of foreign sources, gives an insufficient level of financial literacy of potential participants, the lack of regulations and regulatory infrastructures, describe the problem of accounting and reporting of the results of operations in this segment, insufficient training of market operators and reveals the possibility of expanding the agricultural tools of risk management
Dependence of the fishery efficiency to the number of factors is determined. Dynamics of industry’s profitability is prognosticated. The strategy of development of fishery is fixed. Marketing strategy of reconstruction and development of the fish industry is worked out
Objective: To improve the consistency and effectiveness
of strategic planning and forecasting in
modern conditions it requires development of the
existing classifications of types of planning, strategies,
forecasts and forecast methods. This study examines
the introduction to problems of spectral
analysis of the macroeconomic dynamics of key
world and Russian sugar subcomplex. The article is
devoted to forecasting the activities of integrated
manufacturing systems of sugar subcomplex in agro
industrial subcomplex. As well as to the practical
application of economic-mathematical methods
(based on spectral analysis) to control the economic
parameters of the integrated industrial systems of the
sugar subcomplex, oriented to meet the needs of the
sugar production of the population not only of individuals,
but of the regions and the country as a
whole. Discussion: Procedures to identify and study
the dynamics of periodic components of the development
of the agriculture segment agriculture are
based on methods of spectral analysis of random
processes. The article describes the performed experiments
with various kinds of non-stationary time
series of agricultural sector and food industry sugar
sub-complex. The article presents results of numerical
experiments with the spectra of time series of
sugar production, sown areas, gross harvest and
yield of sugar beet and sugar cane country. Systematic
ideas and methods underlying the spectral analysis
were shown. The article also assesses the results.
Results: The algorithm developed by the author
for the adaptive method of spectral analysis was
implemented by the author in the context of a specific
software product, namely in MS Excel format.
The results of the empirical research confirmed the
possibility of practical use of developed models in
forecasting likely scenarios for the development of
sugar sub-complex in the interests of integrated production
systems. The results are illustrated by numerous
graphs based on real data. We have also
built projection of latent structures of sugar subcomplex in the macroregions. It is revealed that each of
the macroeconomic time series can contain at least
from 2 to 9 harmonics (cycles) of different kind and
strength of impact on the trend
