Over the years the English language has been growing into the world's principal language of science. Many countries other than the English speaking publish mainly in English. According to UNESCO, over one half of the world's science is published in the English language. English has become the only truly global English. The globalization process made Russia a part of the international community. The graduates of universities consequently become part of the international workforce. To make them competitive on the modern job market we are to provide them with the necessary professional skills such as the ability to obtain information and present it effectively both orally and in writing. This paper describes experience and the results of skills courses for post-graduates at Moscow State Aviation University. Through various kinds of activities the post-graduates achieve a certain threshold proficiency in the language.

The methods of teaching French language are considered in the article. They are intended for the students who speak English or learn it as a first foreign language simultaneously. The method of comparative analysis is focused the phenomenon of positive analogies and interference is included as well. The author describes the experience of application of the following methods at the Department of foreign languages of MAI. Furthermore she recommends some training aids and the system of control of knowledge and skills.

The present article shares the experience in using entry tests to assess skills of the students learning English and French languages at the Moscow Aviation Institute (the State Technical University). The authors give a detailed description of making, organizing and checking the language entry tests. The paper deals with some concepts of grading the students according to their knowledge of language after fulfilling the entry tests. Some samples of English and French tests are presented in the article. The method described allows to assess objectively the language skills of the students.

Problems of the text theory, the text's characteristic features and universal properties, the entity and the binary opposition of Language versus Speech (discourse), the text in the inner- and inter-lingual communication and in the foreign language instruction (training) process, the text's grammar aspects and the syntax of the "larger-than-the sentence" entities, the sentence actualization and the theme/rheme relationships within a sentence and a text, etc., are discussed; the notions of "microtext" and "macrotext", as well as the means of implicit expressiveness are presented and described.

The simulator was created and the combined equilibrium equations where solved. The result was the stress (linear strengths) in material and the pressure on pilot's body in anti-g suit or high-altitude partial-pressure suit with laid on bladders in operational status.

This paper focuses on analyzing the stress-deformation relationship of three-layered spherical shell which fixed on ring and taken effect under the shell's sole weight. In the condition of meeting flexibility and stress, the optimizing position of ring on shell and the optimizing parameters of shell has been ascertained that based on the results of analyzing stress-deformation.

The boundary of XX and XXI centuries is a new stage of cosmonautics development. It is a stage of active deployment of low-orbit satellite systems for monitoring and communications as well as international space station. That is why the scientific direction of satellite systems operative planning becomes actual. The problem of operative planning has two main tasks - on-board techni-cal task and algorithmic vs software designing task. The article contains a review of practical sat-ellite systems planning problems and techniques of their solving.

Absorption of a circularly polarized light beam without an azimuth phase structure in a dielectric is considered. We calculate transferring of angular momentum and energy to the dielectric. Our result differs from the result of Loudon [1] (Phys. Rev. A68, 013806). It is found that the torque acting on the dielectric divides into surface and bulk parts in another way and is twice as much as in the paper [1]. To explain the difference a concept of classical spin is used. Absence of the concept in the modern electrodynamics is discussed.

Operational definitions of energy-momentum and spin tensors and the equations connecting these tensors in a curved space and in a space with torsion are considered. According to the definitions, these tensors uniquely localize momentum and spin. By the definition of the spin tensor, as an example, absorption of spin of a circularly polarized electromagnetic wave is calculated for an electro-conducting medium. Such absorption results in an asymmetric energy-momentum tensor of the medium. The widespread objections against a reality of classical spin tensors are considered and rejected. A uselessness of the Belinfante symmetrization procedure is shown. The derivation of the metric energy-momentum tensors is criticized. Attention is directed to an analogy between the momentum and angular momentum conservation laws and the equations of motion of a dipole particle.

The spectral method algorithms for the analysis of stochastic control systems in the unbounded areas of time and phase coordinates are given in the paper. In particular, we consider the computational procedures of non-stationary transfer functions of elementary links such as the differentiator, integrator, amplifying circuit with any given factor, and multiplier regarding generalized Laguerre and Hermite polynomials and functions.
