Сollector mm-wave load circuit of differential stages, as well as the optimization of Q-factor are considered. Optimization of the form of microstrip line in order to increase quality factor is shown. Differential line shorted at one end, at the resonant frequency in the operating mode of the standing wave. At the shorted end of the line voltage is at minimum level, while the current at the maximum, so losses are mainly due to the series resistance of the microstrip line. On the other side of the line, the current is minimized, and the voltage - maximum, so the parasitic losses associated with shunt conductance between the differential lines. This effect use for reducing line losses and increasing the Q-factor. To this end, at the shorted end of the line is necessary to increase the line width and the gap between them, and at the other end to reduce the width and gap.

In a classical ferroelectric material the real condition of the crystals, caused different type defects, leads to insignificant effects of degradation. In systems of firm solutions and difficult oxides эфти effects are the integral physical properties. The features of degradation of phase transitions are available and in a ferroelectric material-relaksorakh.

The synthesis of nanocomposite FeNi3/C based on the PAN, FeCl3 · 6H2O and NiCl2 · 6H2O, whereby the first time by the IR heating at 400 ÷ 700 ° C obtained nanocomposite FeNi3/C FeNi3 particle size of 10 to 80 nm are uniformly distributed UM. Using thermodynamic calculations based on the minimization of the Gibbs energy, confirmed the synthesis of nanocomposite FeNi3/C at T=400 ° C reduction of Fe and Ni with H2, produced during the process of carbonization of polyacrylonitrile with infrared heating. Designed as a nano material of the films can be effectively used as a carrier material for a magnetic information recording superdense. Recording density is achieved in such a carrier (85-100) Gb/dyuym2.

Analyses the cost-effectiveness of investments in environmental protection measures and methods for identifying them. Capital investment in manufacturing ensures increase of profits and the effect of environmental costs is expressed in the form of avoided losses caused by pollution. Through extensive and wasteful environmental management regime many industrial actors enterprises-users of irreparable environmental damage to the Habitat of the region. Of possible solutions to the problem of environmental pollution, it is the ekorestrukturizacia of production and its ecological modernization of environmental pollution requires improvement of existing models for the protection of the environment, optimizing the choice of the most effective measures, radical improvement of socio-ecological and economic climate in the regions. Ekorestrukturizacia national complex branches of industrial and territorial systems and environmental improvements within sectors, forms the most important areas of the «new green industrial policy». Critical issues are handled at the macro level, are the determination of the level and structure of key macroeconomic indicators, including gross domestic product, gross national product. The regional nature conservation is not only and not so much at the enterprises and in industry, where these activities are carried out on the whole of the territory covered by their action. Environmental issues should be based on the economic mechanism of nature protection measures not inconsistent with socio-economic objectives of industrial and territorial systems in General.

In the article the author examines factors and reasons causing the problem of strengthening the power asymmetry as a result of market expansion of trading networks, which is identified by the author as a system empirical trend in the market determining structurization of its organizational field.
Evaluating the high potential of development of format trade in the Russian market, the author concludes that the rapid expansion of trading networks creates enormous pressure on the manufacturing business: increasing potential difference is transforming into asymmetry of market power of network retail trade and production companies that stimulates the process of their extremely non-equilibrium strategic positioning in the system of goods supply in the domestic market of the country.
The author comes to the conclusion that the potential of building mutually beneficial strategic partnership relations between manufacturers and trading networks is today relatively restricted by reason of dominant position of networks in the system of goods circulation in the consumer market. Formation of economically effective and strategically balanced partnership alliance of networks and suppliers occurs predominantly only with medium-sized and large manufacturing FMCG companies which have sufficient level of technological capacity and resources which allow them to produce quality high-tech production adequate positioning of which automatically creates in the market powerful production brand.

The simulation of two-dimensional spherical crystals consisting of a large number of particles is carried out. These shells were analyzed based on their geometric structure and energy distribution. Various types of defects formed in a state of equilibrium is considered. Being shown the ambiguity of the existing method of their interpretation. A new way of describing such defects in the close-packed two-dimensional crystals with different topology is suggested.

At the beginning of the 19th century balconies usually arranged in a mansion on the second floor. Most often, they were made of wooden structures with their own vertical supports. In the second half of the 19th century the use of cast-iron and steel struts rail rolling. Balcony plates are in the form of brick svodikov on rails. In tenement houses balconies began to carry out the scheme on the console (embedded in the masonry exterior walls), departure balconies declined.
At the beginning of the 20th century in the construction of a new material - concrete. Supporting structures balconies as steel beams cantilevered embedded in the masonry. Filling the balcony slabs of concrete performed (rubble mixed with concrete, rebar steel rod in the form of a knitted mesh).
In the mid-60 ÷ early 70s. 20th century 5-storey buildings with brick walls were used precast concrete balcony slabs, cantilever embedded in the masonry (250 mm).
