01.00.00 Physical-mathematical sciences
01.00.00 Physical-mathematical sciences
Description
This article investigates hydrodynamic of experimental electrochemical cell with rotating disk in the cation exchange membrane. We have also investigated the flow in open, with the free surface of the solution and in hermetically closed cells. The main regularities of the hydrodynamics of the experimental cell at its real size were set

01.00.00 Physical-mathematical sciences
Description
This work is a continuation of [1], which was devoted to the investigation of the hydrodynamics of the experimental electrochemical cell with rotating disk cation exchange membrane. This article focuses on the transport of salt ions in a closed cell at different initial experimentation with modes of exact current regimes. The main regularities of transport of salt ions and membrane equal accessible surface were set

GENERAL RELATIVITY AND GALACTIC METRICS
01.00.00 Physical-mathematical sciences
Description
It is shown that the metric of the galaxy should be universal, depending only on the fundamental constants. There are examples of universal metrics obtained in Einstein's theory of gravitation and Yang-Mills theory. The axial-symmetric solutions of Einstein’s equations for a vacuum are applied to explain the rotation of matter in spiral galaxies

THE HIGHER ASYMPTOTIC EXPANSIONS FINDING FOR BOUNDARY VALUE PROBLEM OF THE ZOM MODEL
01.00.00 Physical-mathematical sciences
Description
In this article authors propose the asymptotic solution of the boundary value problem modeling the transport of salt ions in the cell electrodialysis desalination unit. The domain of the camera desalting broken into two subdomains: electroneutrality and space charge. Subdomains has own asymptotic expansion. The subdomain of the space charge has unique solvability of the current approach used by the solvability condition of the next approximation

BASIC IDEAS OF INTERVAL DATA STATISTICS
01.00.00 Physical-mathematical sciences
Description
In the article we have considered the basic idea of asymptotic mathematical statistics of interval data, in which the elements of a sample are not the numbers, but the intervals. Algorithms and conclusions of interval data statistics fundamentally different from the classical ones. The results related to the basic concepts of notna and rational sample sizes are listed. Interval data statistics as an integral part of the system of fuzzy interval mathematics is shown

GENERAL RELATIVITY AND METRIC OF LOCAL SUPERCLUSTER
01.00.00 Physical-mathematical sciences
Description
It is shown that the metric of clusters of galaxies should be universal, depending only on the fundamental constants and compatible with the metric of the universe. There are examples of universal metrics obtained in Einstein's theory of gravitation. On the basis of axisymmetric solutions of Einstein’s equation proposed universal metric describing the properties of galaxies, groups and clusters of galaxies

Description
The method of nanoemulsions obtaining with acoustic chemistry method has been considered in the article, the nanoemulsion formula has been found. The researches for emulsion stability and particle sizes determination have been fulfilled. The antioxidant effect of the obtained emulsion and a possibility to use it in meat-vegetable products have been researched

PROBLEMS OF DEVELOPMENT OF COM-POUND COMPOST
Description
Compound compost during its formation involving organic and mineral wastes retains the organic matter by reducing its degradation products with nitrifying and denitrifying organisms due to its economical ex-penditure of phosphorus and calcium, increased am-monia and total nitrogen, formation in the process of development of calcium sulfate with participation in its formation of residue calcium salt and ammonia

FEATURES OF PATHOLOGICAL CONDITION OF URBAN PLANTS IN VORONEZH
Description
The comparative analysis of the condition of green plantings of the city of Voronezh is carried out. The objective differences in the pathogenesis of native and introduced species of forest plants are identified
-
Description
It is shown that under in vitro conditions, regenerated plants of Lilium caucasicum cultivated in the light of varying intensity and spectral composition didn’t have the same biometric parameters (length and width of leaves) or number of micro bulbs. There were established some specific effects of the two main areas of photosynthetically active radiation - blue and red on the growth and development of the plants as well as on the content of photosynthetic pigments
