EFFECT OF DEFORESTATION ON THE BIOLOGICAL PROPERTIES OF MOUNTAIN SOIL OF WESTERN CAUCASUS
DescriptionEFFECT OF DEFORESTATION ON THE BIOLOGICAL PROPERTIES OF MOUNTAIN SOIL OF WESTERN CAUCASUS
-
Description
In the article, we have proposed regional environmental standards for heavy metals, oil and oil products in the main soils of southern Russia

Description
In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear

Description
Particular qualities of growth of homofermentative lactic acid producer Lactococcus lactis CH5 depending on the composition nutrient medium: glucose and yeast autolysate concentration are examined in the article. The influence of the method of cultivation on the productivity and the speed of the lactis acid synthesis is analyzed

MATHEMATICAL MODELING OF FINANCIAL PYRAMID SCHEME. PART 2. DISCRETE MODELS
01.00.00 Physical-mathematical sciences
DescriptionThis article analyzes the changes in the number of cases of various clients of the pyramid and the establishment of the basic rules of the pyramid schemes based on discrete models. The article is also a continuation of previous work [1], which had formulas to simulate the amount collected by the pyramid scheme

MATHEMATICAL MODELING OF FINANCIAL PYRAMID SCHEME. PART 1. DEFINITIONS
01.00.00 Physical-mathematical sciences
DescriptionThe article analyzes the various approaches to the mathematical modeling of financial pyramids. It considered “economically rational subject”, game approach and the approach of Dubovsky. In this article, the mathematical models of the unproblematic approaches examined; we also analyzed their characteristics, including the dependence of the lifetime of the pyramid of accrued interest and the number of clients, the maximum possible profit of the founders of the pyramid, etc. This work analyzes the various options of the campaign, including whether the implicit advertising company, which arises from the spread of the financial company clients and rumors about their income

MATHEMATICAL MODELING OF FINANCIAL PYRAMID SCHEME. PART 2. CONTINUOUS MODELS
01.00.00 Physical-mathematical sciences
DescriptionThis article is devoted to the analysis of different cases of changing the number of customers of the financial pyramid and the establishment of the basic rules of the pyramid schemes on the basis of continuous models, and it is a continuation of works [1, 2], which had formulas to simulate the amount collected by the pyramid scheme and it considers the discrete models

INTERFEROMETRIC METHOD OF LASER RADIATION TRANSMISSION USING FREE SPACE OPTICS
01.00.00 Physical-mathematical sciences
DescriptionThe analysis of the various conditions of the two (four) laser radiation streams coherent addition was realized. It is shown that it is possible to create devices providing continuous subtraction of waves. In such radiation stream a continuous subtraction on the line can be replaced by the continuous addition on the photomultiplier by using a dispersive delay line. The research results can be used for creation of modern open atmospheric connection lines
