The article offers a comprehensive assessment of the linguistic viability of Russian as a heritage language in the United States, following a framework that provides three factors involved in promoting language vitality (Lo Bianco, 2008a, 2008b): capacity, the level of knowledge that heritage speakers of Russian have in the heritage language and the factors that create conditions for development of such capacity; opportunities for the use of Russian in different domains and contexts; and heritage learner motivations and desire for continued use of Russian and for developing the skills necessary for its maintenance and transmission

Plasma arc gasification is an emerging technology for generation of renewable energy and other by-products from a variety of waste. This bold technology is under development in a number of locations around the world, although it is too early to fully know if the technology is technically feasible and economically viable on a truly heterogeneous municipal waste stream like that found in the U.S. Plasma arc technology in the United States in other applications dates back approximately 40 years when it was utilized by NASA to test heat shield materials for spacecraft. In 1989, plasma arc technology was used in an iron melting furnace in Defiance, Ohio (USA). Plasma arc gasification has been used in municipal solid waste destruction since 1999 in Japan for destruction of solid waste and automobile shredder residue. Plasma arc gasification heats waste materials to temperatures in excess of 10,000 degrees Fahrenheit (°F) to break the molecular bonds and gasify the materials. This liberates the energy potential of the waste materials and melts the residue to an inert, glass-like slag, which may be used as an aggregate in construction and manufacturing operations. If this market can be developed, it will significantly reduce the need for landfill disposal in the future. St. Lucie County, Florida (USA), is in the process of negotiating with a developer for the construction of a plasma arc gasification facility that will process 1,000 tons per day of municipal solid waste. The facility may be the first large scale solid waste plasma arc processing facility in the United States. Camp Dresser & McKee is assisting St. Lucie County to negotiate the agreements for this project. The project is expected to be privately financed, so the County will not be putting any money at risk. In this paper, we will describe the plasma arc technology, present its historical applications, and discuss the St. Lucie project from initial conception to its current status.

This article will present the result of an analysis of the geopolitical and geo-economic interests of China, Russia and the United States in the Central Asian region. Central Asia is a field of world power collision because of this region is characterized by an advantageous geostrategic position, communication and energy opportunities, and a significant stock of natural resources. The strategy implemented by China is aimed to cooperate in the development and transportation of hydrocarbon raw materials, the development of the region’s energy potential, the development of hydro resources, the development of transport communications, and industrial facilities. China takes first position of investments and loans in the economy of the republics. There is a cooperation in the fight against terrorism, extremism, drug crime. The United States is pursuing its own national interests in Central Asia in the military-strategic sphere, as well as by investing in the development of the oil and gas industry. The weakening of Russia and China influence in the region also belongs to the national interests of the United States. The realization of Russian’s geopolitical interests is connected with ensuring national security by protecting state borders, combating terrorism and religious extremism, drug crime. Geo-economic interests are associated with the development and transportation of natural resources (hydrocarbon raw materials), cooperation in the energy and transport and transit sectors. In addition, in this article will be analyze a number of geopolitical models that characterize Russian policy in Central Asia.
