The article considers the modern parameters of development of enterprises of metallurgical complex of the Russian Federation, determining the prospects of their competitiveness in the world market of non-ferrous metals. The role of the metallurgical complex is indicated, the market segments by types of metals and their impact on the economy are determined. The dynamics of prices on non-ferrous metals markets, as well as macroeconomic indicators are analyzed.
Identified strengths in the work of metallurgical enterprises: production growth; stability of the macroeconomic environment; market capacity; introduction of modern technologies. Besides, negative determinants of their activity are defined: wear of technical equipment; localization of reserves of raw resources; underutilization of production capacities; shortage of qualified personnel.
The vector of the direction of development and improvement of metallurgy is specified. The logical result of the study was the conclusion that the enterprises of the metallurgical complex of the Russian Federation need to increase production efficiency by increasing the capacity of individual units; improve the quality of steel products; implement technological modernization; form technological clusters that realize the production potential of metallurgy and improve the technological uniformity of production.The article is devoted to the system of factors and criteria indicators necessary to assess the economic efficiency of the use of construction machines and the solution of relevant optimization problems.
The article, in particular, analyzes the possible criteria for the efficiency of construction equipment (net present value, profitability, unit costs, discounted costs), indicates the scope of their application, reveals the factors (technical, organizational, climatic, economic) that affect the productivity and cost of use of machines, as well as the overall efficiency of the equipment. Provides an overview of the individual works performed in recent years and affecting certain aspects of the performance of construction machinery. The importance of professional standards of the profession "Machinist" (by types of construction machines) is pointed out. Emphasized the need for a differentiated consideration of the terms of the lease agreements and leasing.
At the end of the article it is concluded that it is necessary to conduct a quantitative analysis of the influence of certain factors on the values of criteria indicators.Military Affairs

One of the most important physical qualities defining health and efficiency of the person in any kind of activity is the endurance. Among all physical qualities it is one of the most powerful indicators of assessment of level of a physical state and physical fitness of the person. Along with the speed providing the speed of performance of this or that movement, speed of simple or difficult reaction and, respectively, efficiency and timeliness of performance of labor or other physical actions, development of endurance is one of important problems of professional and applied physical training of automobile and road specialties.
Among huge variety of the physical exercises contributing to the development and improvement of these qualities the most popular and most effective exercises for development of endurance and speed are presented in article on the basis of the analysis the Internet of resources. The basic methodical provisions of development of these physical qualities are given.
