    Kharchenko, N.V.; Piskunov, A.E.; Roser, S.; Schilbach, E.; Scholz, R.-D. (Кинематика и физика небесных тел, 2005)
    We present the results of a systematic study of the wider neighbourhoods of 520 Galactic open clusters from data of the all-sky high-precision homogeneous catalogue ASCC-2.5. About 30 000 members have been selected on the ...
  • All types of coherent radiations, which arise in the collision of relativistic electrons with crystal 
    Morokhovskii, V.L. (Вопросы атомной науки и техники, 2015)
    The general quantum theory, that describes all types of X-and-γ-rays coherent radiations, which arise in the collision of relativistic electrons with a crystal target, is described briefly. Such types of coherent radiations ...
  • Alma mater 
    Автор відсутній (Україна. Наука і культура, 2009)
    Сьогодні ніхто вже не скаже: вчуся в Києві в університеті, бо це тільки викличе нове запитання — тобто в якому? Університетів у Києві тепер — скільки? — принаймні понад двадцять, з них тільки національних, здається, ...

  • Almost all derivative quivers of artinian biserial rings contain chains 
    Avdeeva, T.; Ganyushkin, O. (Algebra and Discrete Mathematics, 2003)
    A lower estimate for the number Mn of all labelled quivers with n–vertex parts of Artinian biserial rings is given and the asymptotic of the relation Mn/Bn, where Bn denotes the number of those quivers all connected ...
  • Almost MGP-Injective Rings 
    Zhu Zhanmin (Український математичний журнал, 2013)
    A ring R is called right almost MGP-injective (or AMGP-injective) if, for any 0 ≠ a ∈ R, there exists an element b ∈ R such that ab = ba ≠ 0 and any right R-monomorphism from abR to R can be extended to an endomorphism of ...
