Russia’s National Interest in Terms of Communicative Competence of Engineers

The article deals with the Russia’s national interest in the framework of the development of communicative skills of international level engineers and managers. Territory integrity and borders continuity are the key aspects of Russia’s national interest. The rest aspects such as wealth, prosperity, culture, etc. are derived issues. Russia’s national interest means survivability and sustainability of the state. Global world introduces new forms of national interest assertion based on interstate, cross-national and individual communication. Quality of communication – diplomatic, professional, cultural – plays the key role in this assertion. Pilot school Proficient English in the Business World (PEBW BMSTU) acting in Bauman Moscow State Technical University is aimed at the formation of Russia’s engineering elite capable to work in favor of Russia. ‘National interest – Corporate culture – Individual values’ ternary implies the fundamental essence of training process and determines its national interest orientation.Commercial education, international students’ educational initiatives such as well known BEST and ESTIEM lack the bonds of the ternary and actually give no contribution to the sustainability of the state. Trainees follow mainly only individual goals because all is paid off. PEBW simulates virtual business company. Interdisciplinary training in English forms the intrigue of students’ involvement and belonging, need for self-expression and leads to the formation of mentality corresponding to the national interest of the country. As a kind of out-of-theclass activity, students of PEBW School organize and conduct visits of international delegations, polishing the skills achieved in training and getting immediate feedback of their contribution to the national interest assertion. Opinions of the school graduates presented in the article evidently illustrate the proof of the training passed. Atmosphere and attitude existing in the PEBW class was witnessed by the chief editor of ‘The Moscow Times’ newspaper, who visited the class and later wrote to the director of the school, – «I was delighted by your class and completely enchanted by your students. They give me hope for the future of the country».</p

Optical properties of excitons in CdS semiconductor-insulator quantum wires

The characteristic features of the luminescence spectra of CdS semiconductor nanocrystals, crystallized in hollow channels in a dielectric template, are explained in terms of excitonic transitions in semiconductor-insulator quantum wires. The excitonic transition energies agree with the values calculated taking into account the effects of size quantization and the “dielectric enhancement of excitons” — the large increase in the electron-hole attraction as a result of the difference between the permittivities of the semiconductor and insulator. The theoretically computed binding energies of excitons in CdS quantum wires with a diameter of 10 nm reach 170 meV. It is shown that the excitonic transition energy is constant for a wide range of wire diameters
