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. 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 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

HYDRODYNAMIC PRESSURE OPTIMIZATION METHOD IN A WELL AT ROUND-TRIP OPERATIONS
DescriptionThe aim of the article is to study the effect of velocity and acceleration of a drill string on hydrodynamic pressure in a well. We obtain the formulas of pressure versus time. We also established the method for optimizing hydrodynamic pressure in a well at round-trip operations

MINERAL AND VITAMIN SUPPLEMENT IN FEEDING OF REARING FLOCKS
06.00.00 Agricultural sciences
DescriptionThe studies have determined the effect of bentonite clay, vitamin complex "microvan Blend" and BAKD of local raw materials for the viability, the growth and the development of the young rearing flocks of the “Hisex brown" egg cross. To improve the quality of the grown rearing flocks and pullets increased yield, egg poultry farms were proposed to use the bioactive feed additive (BFA) made from local cheap raw materials (bentonite clay, sunflower oil, drug-soluble vitamins A, D3, E and antioxidants)

Description
The global financial crisis has had a negative impact on the domestic economy, resulting in a much more complicated task of achieving the most important indicators specified in the Concept of long-term socio-economic development of the Russian Federation until 2020. Implementation of the goals depends on a number of factors, including, how successful energy efficiency policy in Russia will be implemented. In this regard, actual task is to analyze the impact of the energy factor on the dynamics of change of gross domestic product in Russia
