The specifics of training of students of forest profile of bachelor 's degree in discipline "Technology and equipment of discontinuous and low-volume cuttings" are considered. There is a list of questions for the front survey of students.

In given article the technique of planning of carrying out of research and development on the basis of the volume determined models is described. Basically, the problems concerning top level of hierarchy, namely, problems of definition of the schedule chart of realization of the basic stages of research and development and volumes of expenses necessary for it are considered. The most effective and modern approach to realization of such substantiation is use of mathematical models. It is thus essential that the models applied to the decision of problems of this level, should consider not only internal properties of the enterprise are models of its organizational system, but also consider with accessible completeness of property of environment of the enterprise. As this completeness is rather limited, in view of incompleteness of the information on properties of environment of the enterprise, the planning technique should provide possibility of correction of planned offers, their recalculation under the specified data.

The monograph contains research of background radiation of the population from natural radionuclides in the premises of the Lower Volga region and presents methods of protection against the influence of natural radionuclides. Direct studies have established the absorbed dose rate of the Lower Volga region in the premises of wooden, brick and concrete buildings. The frequency distribution of the effective specific activity of natural radionuclides in building materials is analyzed. It has been established that the dose received by the body over a long period leads to more serious damage than the same dose received in a short period.

In this article the problem of radioactive effect of radon on the population of the Lower Volga region is considered. The studies made it possible to calculate the averaged annual effective equivalent doses to the population of the Lower Volga region, caused by radon and daughter products of decay. Methods for reducing radon exhalation using different types of finishing materials are proposed.

The article contains characteristics of forest residues. In the analysis it was found that the billet, chernivsti and usage of logging residues has a significant influence the volume, size, strength and contamination.

A comprehensive financial and economic analysis of the activities of the two largest fright railways of the first class of the United States was carried out in the article. This analysis has made it possible to identify a number of tools and methods that ensure the achievement of a level of financial efficiency and a previous level of profitability, while reducing the volume of cargo transportation.

The graphs of cylinder-piston group’s temperature dependences on the changes of the engine speed are presented in this article. Experimental researches show, while using different working masses in pumping section it is possible to decrease cylinder-piston group’s temperature.

In this article studies of radiation radon characteristics of sites for the construction of the Volgograd region are presented. The regularities of radon distribution at the objects of the construction complex were established, depending on the influence of various factors. The studies made it possible to calculate the average annual effective equivalent doses to the population of the Volgograd Region caused by radon and daughter decay products.

This article provides studies of radiation (radon) characteristics of premises in the Volgograd Region. The purpose of the study was to identify factors of the radiation background caused by radon in civil engineering objects. The regularities of radon distribution at the objects of the building complex are determined depending on the influence of various factors. The studies made it possible to calculate the average annual effective equivalent doses of exposure to the population of the Volgograd Region caused by radon and daughter products of decay.

Some features of the working program of the discipline "Technology and equipment of discontinuous and small-volume logging" are considered in the course of training bachelors in the direction: "Technology of logging and woodworking industries".

Performed the market of low-rise wooden housing, the basic trend of the market analysis, the factors influencing the market of low-rise construction.

The article is devoted to a model construction, which shows how the volume of electricity production by nuclear power stations depend on the power of these stations. The authors demonstrate correlation and regression analysis, evaluate the statistical significance of the model.

In his article the author investigates didactical and methodical aspects concerning formation of object affilation to notion volume skill in the process of mathematics teaching at school.

Describes the features of the construction of the block diagram modeling the shape and volume of tree trunks to predict the output of trunk wood with forest land according to the taxation data.
