N=4 supersymmetric Eguchi-Hanson sigma model in d=1

We show that it is possible to construct a supersymmetric mechanics with four supercharges possessing not conformally flat target space. A general idea of constructing such models is presented. A particular case with Eguchi--Hanson target space is investigated in details: we present the standard and quotient approaches to get the Eguchi--Hanson model, demonstrate their equivalence, give a full set of nonlinear constraints, study their properties and give an explicit expression for the target space metric.Comment: LaTeX, 9 page

Synthesis and Characterization of Organic Impurities in Bortezomib Anhydride Produced by a Convergent Technology

A profile of impurities in bortezomib anhydride, produced by a recently developed convergent technology, has been characterized. HPLC-MS analysis of the drug essence revealed three impurities: an epimer of bortezomib, resulting from partial racemization of l-phenylalanine’s stereogenic center during the chemical synthesis, and two epimeric products of oxidative degradation of bortezomib, in which boron is replaced by the OH group. The impurities were obtained by chemical synthesis and characterized by physical methods

Jogo ciberrealidade como um implemento de impacto de conflito sobre a segurança nacional da Federação Russa

The research objective is the identification of the negative image of the Russian state in computer games of the western developers. The characteristics and tendencies are given in the development of virtual game space from the first person (shooters) where the image of the enemy of the Russian origin is created. Virtual game communications are considered as a special form of social interaction on the Internet where technologies of political convictions and increase in level of hostility of rather specially chosen object are approved.The research has cross-disciplinary character. When studying virtual game network space authors used structurally functional and sociocultural approach.Computer games can serve as platform for the information wars, first of all, directed against the Russian youth.Destructive communicative strategy is used in the computer games devoted to World War II where the role and value of participation of the Soviet Union in a victory over fascist Germany is leveled. It is reached in fictional images of Russia in virtual reality which do not relies on objective reality of historical process and carries a negative connotation.Computer games are time the tool which can put motives of political and ideological hatred, xenophobia or hostility concerning any social group or the country.El objetivo de la investigación es la identificación de la imagen negativa del estado ruso en los juegos de computadora de los desarrolladores occidentales. Se dan las características y tendencias en el desarrollo del espacio de juego virtual de la primera persona (tiradores) donde se crea la imagen del enemigo del origen ruso. Las comunicaciones de juegos virtuales se consideran como una forma especial de interacción social en Internet donde se aprueban las tecnologías de convicciones políticas y el aumento en el nivel de hostilidad, especialmente, del objeto elegido. La investigación tiene carácter interdisciplinario. Al estudiar el espacio virtual de red de juegos, los autores utilizaron un enfoque estructuralmente funcional y sociocultural. Los juegos de computadora pueden servir como plataforma para las guerras de información, en primer lugar, dirigidas contra la juventud rusa. La estrategia destructiva de comunicación se usa en los juegos de computadora dedicados a la Segunda Guerra Mundial donde se nivela el papel y el valor de la participación de la Unión Soviética en una victoria sobre la Alemania fascista. Se alcanza en imágenes ficticias de Rusia en la realidad virtual que no se basa en la realidad objetiva del proceso histórico y conlleva una connotación negativa. Los juegos de computadora son la herramienta del tiempo que puede poner motivos de odio político e ideológico, xenofobia u hostilidad con respecto a cualquier grupo social o país. Objetivo de pesquisa é a identificação em jogos de computador dos desenvolvedores ocidentais de projetar a imagem negativa do estado russo.

Improving the Mechanical Properties of SiC-ceramics by means of Vacuum Electron-ion-plasma Alloying with Titanium

The investigation results of elemental and phase composition, state of defective substructure and microhardness of the surface layer of "film (Ti)/substrate (SiC-ceramics)" system (Ti film 0.5 [mu]m thick was deposited on the surface of SiC-ceramics) subjected to treatment with an intense pulsed low-energy electron beam (15 J/cm{2}, 200 [mu]s, 0.3 s{-1}, 20 pulses) are presented. It is shown that irradiation of the "film (Ti)/substrate (SiC-ceramics)" system with an electron beam is accompanied by the formation of multielement multiphase (SiC; TiC; Ti5Si[3]) surface layer having submicro- and nanocrystalline structure. Microhardness of the irradiated surface layer reaches a value of 74 GPa, that is twice the value of microhardness of SiC-ceramics (36 GPa)
