The latest requirements for specialist training in the system of higher education in the Russian Federation call for enhancement of foreign language learningand improving foreign language teaching. The aspect of interdisciplinary link between foreign language learning and cross-cultural communication is emphasized in the article. We suggest that in order to overcome cultural and language barriers we need to actively engage experts in cross-cultural communication in foreign language teaching, particularly, for science students.

Piezoceramics phases of (1-х)PbTiO3-xPbZrO3 is the basis of most high-performance piezoelectric materials. Electrophysical and mechanical properties of these materials can be varied over a wide range by varying the composition and by processing methods: the methods and modes of sintering conditions polarization. Topical to study the influence on the properties of PZT materials processing methods at the stages of manufacturing piezoelectric samples. In the role model of the object has been selected multicomponent system PbTiO3-PbZrO3-PbNb2/3Zn1/3O3-PbW1/2Mg1/2O3-PbSb2/3Mn1/3O3. Samples of piezoelectric elements for the study were obtained in two ways: in the first case, the sintering samples was carried out by the usual ceramic technology, and in the second by hot pressing. The grain structure was formed in both cases in the presence of the glass phase, the quantity of which decreases with increasing temperature, while in the first case, an increase in the velocity of the secondary recrystallization, and in the second of its suppression. It was found that regardless of the technology of the samples εT33/ε0, d33 and VЕ1 at high temperatures, due to the increase of grain and coercive field, which complicates the process of polarization. Maximum values εT33/ε0, d33 and VЕ1 samples prepared by hot pressing at 10 - 15% higher than if received by conventional ceramic technology.

Strength properties of high-strength concrete on the basis of a mixture of high-calcium ash and cement crushed to a specific surface of 600 m2 / kg in the presence of a superplasticizer were investigated. It was established that at the initial stages of hardening of the binder, its strength strongly depends on the dosage of fly ash and it depends little on the water/binder ratio. After 28 days of hardening, the strength of concrete, depends more on the water-binder ratio, rather than on the ash content of the cement-ash binder. There was concluded that minerals of fly ash affect on strength of the cement-ash binder in later periods, and at the initial stages, its hardening is provided by hydration of the cement clinker. It was established that in high-strength concretes was no decrease in strength in later periods when using finely grinding ash containing a significant amount of free CaO.

Thermoresistors nowadays are used not only as parts of temperature sensors and flowmeters but they are used as components of starting and control devices. Use of low-powered thermoresistors as starting and control devices parts needs a lot of devices that reduces equipment reliability. Current step-up running through motor-starting devices simplifies control circuit. For using thermoresistors in electric circuits with high-discharge rate it is necessary to use special constructions in order not to let termoresistor body be overheated. Thermoresistor expansion results in changing of thermal fields distribution pattern inside this semiconductor. The authors show calculated characteristics which let determine proportions and shapes of semiconductor subject to thermoresistor temperature.

The article describes the role of reduced order models (ROM) in MEMS design & testing, reflects their advantages in comparison with the finite element method (FEM) full models for real-time behavioral modeling of MEMS dynamic characteristics and versatile research of the objects' properties. The mathematical interpretation of the procedure for reducing the system dynamics equations order by switching from the full model presented in the form of state variables equations to the ROM state variables equations is given, the four existing scientific methods for reducing the FEM model order are presented in generalized form. The particularities of embedded ANSYS software capabilities application to automatically generate the ROM from the original full FEM model with lower computer power requirements and the preservation of the original model accuracy in the presence of only the structural mechanics are set out in details. Two equal algorithms for further work with the ROM in MatLab software in order to simulate the MEMS dynamics and study time and frequency properties of the model are presented: by designing the scheme consisting of prearranged Simulink function blocks and by writing an M-file program listing using the special MatLab programming language. Scientific novelty of the results is the combination of the methods for MEMS design (system of partial differential equations, ANSYS program) and behavioral modeling (system of ordinary differential equations, MatLab program) that can significantly reduce the complexity of the FEM model adaptation to the real-time modeling and eliminate computation errors.

A promising direction of creation of new lubricants is their modification by nanoclusters of metals, which form in the zone of friction of the protective film, providing reduction of wear of friction pairs. In this regard, the aim of this work is to study tribological properties of lubricating compositions containing nanosized particles of lead and palladium. A lubricating composition was obtained in aqueous solution during electrolysis with a lead anode or in the presence of salts of palladium in an ultrasonic field (complex processing). Tribological studies showed that the lubricating compositions have high anti-wear and extreme pressure properties.

One of the most important elements of the bridge, from which the service life of this structure directly depends, is the supporting part. It provides the movement and rotation of span structures, as well as the transfer of all loads from the forces acting on them to the supports. The task of the designer is to select such support parts, that could be allowed maximum reducing of the forces, acting at the ends of the beams and having a minimum resistance to their free movement. It is necessary in each case to select the support part, which will most closely meet the requirements. To solve this problem, the author structured and tabulated the kinds of support parts. And also an analysis of the main characteristics of some of them.

This article discusses some of the problems arising in the study of political processes of network modeling methods. The relation of concepts, models and their practical application in the analysis of political events is analyzed. The purpose of work is to examine the hypothesis testing problem in the practice of political analysis using empirical methods in the field of cooperation between public institutions and networks of civic engagement structures. It is shown that the use of network modeling methods to move from descriptive methods, cluster analysis to statistical models, reproducing the interaction of political subjects, which makes it possible to produce test of hypotheses by empirical methods. Statistical models combine the methods of qualitative analysis and quantitative methods of hypotheses verification and application of the results of various concepts in political practice. Revealed the limitations of the use of the research capacity of the network models, associated with incomplete empirical data obtained during the field research that requires the experiments, various forms of observation and interviews.
