The article analyzes and summarizes the principles of architectural bionics applied to various construction and technical structures. The analysis was carried out in the course of studying the scientific literature on the topic “Bionics. Architectural structures». The purpose of this work is to study the principles of architectural bionics, to study the possibility and effectiveness of their application for solving engineering and technical problems. The main task of the work was to study the directions and principles of development of architectural bionics, to assess the effectiveness of their application for solving technical problems, to find the correspondence of biological systems to construction and technical structures and facilities, to analyze known architectural structures from the point of view of architectural bionics.

Graphenes in the form of flexible thin films treated with different types of plasma were investigated by Mott-Schottky analysis. The possibility of variation of electrical conductivity in graphene prepared by plasma treatment was shown. Obtained materials are promising for electric energy storage devices.

Using the electronic database of FIPS, the directions for the development of new methods and devices of Russian forestry universities, patented in 2017, have been examined.

There are two different ways to transmit the AC electric power for a long distance: a compensated, the half-wave and tuned to half-wave transmissions. The compensation of the wave length is an effective way to increase the distance and the capacity of the transmission line. Through the wave length compensation it might to give to a long distance line the properties of the short line (except the active power losses). But with the distance and capacity increasing also increases a capacity of the compensation devices. Therefore, usage of the half wave and tuned to a half wave transmission lines to transmit an AC electric power for a long distances is more effective because there is no need to additional expenses to reactive power compensation by the stability conditions. The boundary length of the tuning to a half-wave is defined in article. The advisability of the tuning to a half-wave is arises when the length of the line more than 1500 km. Otherwise it recommended to tune the line to a «zero length».

An analysis of two variants of charging shared utilities is conducted, advantages and disadvantages of each variant are considered. Recommendations for optimization of expenditures for houseowners are given in view of the active legislation

The article presents the research of spintronic devices. According to the authors, using extraction and pyrolytic method it was possible to obtain tertiary oxide in La-Sr-MnO system and to research magnetic behavior of obtained film.

This article describes the role of educational mobile applications in learning English. The authors focus on the didactic characteristics of educational mobile applications and their capabilities.

The article is devoted to a brief review of modern CAD for electromagnetic modeling of microwave devices. Five major CAD systems are described in the article: FEKO, μWave Wizard, Sonnet, AWR Microwave Office, HFSS. The main methods are given for each CAD system used for simulation of microwave structures and the main advantages that distinguish its use.

The article shares personal experience in teaching a foreign language to non-linguistic students. The author reveals the problems facing professors and gives recommendations on how to develop the language skills. Working with electronic means of information transmission has proved to be highly effective.

This article describes the basic concepts of silica nanofibers, their unique properties. There are analyzed the transmission of radiation between these fibers.

The article discusses the role of mobile applications among youth on the example of mobile guide «Education of the Russian Federation», assistant of the applicant, which contains all the necessary information on directions and training profiles, as well as all information about the University. In this app you can find information about each school, gymnasium, lyceum and college. This mobile application is one of the most convenient tools to obtain the necessary information to applicants and students of our country.
