... Properties of Stellar Populations in Isolated Lenticular Galaxies I. Yu. ... The resulting average ages of the stellar population in bulges and discs fill an entire range of possible values from 1.5 to 15 Gyr which indicates the absence in the isolated lenticular galaxies, unlike in the members of groups and clusters, of a certain epoch when the structural components are formed: they could have been formed at a redshift of z > 2 as well as only several billion years ago. ... 69 NGC 2350 No. ...

... Objectives of the study . To survey and evaluate the technical and economical feasibility of European initiatives by start-up companies, for privately-funded crew vehicles for commercial human space flight. ... New commercial markets, among them space tourism, have a great potential to become major drivers in space technology development. This study aims at the assessment of the feasibility of European initiatives to address these new markets through the development of crewed space vehicles. ...

A methodical and didactical complex "Sign Language" . ... ABSTRACT The process of communication of the deaf includes the wide use of the sign language. ... The aim of this work is to develop a tool that should facilitate process of sign language teaching and also give to the trainee a means for independent study of various normative variants of sign language - for example, Russian, English, International and so on. ... The process of dialogue of the deaf people includes wide use of sign languages. ...

... A non-linear relationship is observed between the sky brightness on clear and overcast nights, with a change in behavior near the rural to urban landuse transition. ... The great variation in skyglow radiance observed from site-to-site and with changing meteorological conditions underlines the need for a long-term international monitoring program. he introduction of artificial light has caused an unprecedented disruption to the nighttime environment over large areas of the Earth. ...
