The article deals with the model of two-step combined control of municipal unitary enterprise in the conditions of uncertainty, which is different from well-known and widely used model of operative correction of specifying current information
The article deals with the models of analysis of a target product’s load flow in the indignant condition of a production corporation against loss of information definiteness of boundary conditions. The classification of the boundary conditions for the stationary conditions of the studied fragment of system is given
The processes of momentum transfer in laminar and turbulent boundary layers are considered. We have obtained the proprietary models for calculation of shear stresses, turbulent viscosity, friction factors, boundary layer thickness and momentum transfer coefficients in boundary layers under different conditions of motion of media. The examples of the calculation of the above characteristics and their agreement with known experimental data are shown. The obtained equations and the methods of calculation of the boundary layer characteristics can be used for calculations of industrial heat and mass transfer apparatuses of various designs as well as of some other types of equipment
The efficiency of mineral and bacterial fertilizers ap-plication for various agricultural crops (watermelon, soy bean, millet and potato) is investigated in the Rostov region. We established the bacteria stocks un-der each culture, allowing to receive the greatest in-creasing of productivity, both on a natural background of fertility, and in a combination with mineral fertiliz-ers: for soy bean - 626а, watermelon - Azorizin-8, millet - Azorizin-6, potato - 18-5. The optimum com-binations of mineral and bacterial fertilizers for each culture are established
The article demonstrates the taxation parameters of the pine plantations that was damaged by fire in 2010 in Suburban forestry of the Voronezh region and was calculated the basic ecological functions they performed before death. The intercommunication was found between increasing level of air pollution in the study areas and growing of heart and pulmonary morbidity of population
In the article, we made an estimation of pine cultures’ (Pinus silvestris L.) sanitary condition in the Savalsky Forestry area of the Voronezh region. The obtained results show their considerable weakness, passing to the drying phase because of pine fungus
The 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
The 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
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
This article gives the review of the analysis of the content of the concept of “theatricality” in both linguistic and extralinguistic contexts
