    The chaotic behavior in the global climate system of the Earth and the nonlinear interaction between some teleconnection patterns during different epochs of the twenty century are studied. To study the influence of low ...
  • Belyaev, A.E.; Boltovets, N.S.; Konakova, R.V.; Kudryk, Ya.Ya.; Sorokin, V.M.; Sheremet, V.N.; Shynkarenko, V.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2011)
    Some aspects of measuring the thermal resistance to a constant heat flow at a p-n junction–package region in IMPATT and light-emitting diodes are considered. We propose a method of studying the thermal resistance of ...
  • Ostrovetskyy, V. (Економічний вісник Донбасу, 2016)
    As a result of the macroeconomic assessment of fiscal policy found an inverse relationship between the level of tax burden on economic growth and the physical GDP. It suggested several ways of reforming the tax legislation, ...
  • Rudavskii, Yu.; Ponedilok, G.; Petriv, Yu. (Condensed Matter Physics, 2001)
    The quantum-statistic problem of atoms chemisorption with hydrogen-like electronic structure on semiconductor and dielectric crystalline surfaces is considered. The superficial states are described in tight-binding ...
  • Кистол, Л.П.; Тюнина, Е.В. (Культура народов Причерноморья, 2005)
    В статье предлагается использовать применение интернет технологий в процессе преподавания английского языка студентам компьютерных специальностей технических вузов. Следует подчеркнуть, что в то же время с применением ...
  • Dochev, M. (Економічний вісник Донбасу, 2010)
    The accounting information is a corner stone when making appropriate managerial decisions and providing economic indicators to external contractors. To this end it is necessary that while keeping business accounts the ...
  • Sirenko, B.I.; Smirnov, I.S. (Український антарктичний журнал, 2012)
    According to the rule of de Candolle-Walles a species diversity decreases from low latitudes regions to high latitudes regions. However in the Weddell Sea the biodiversity of the fauna of some groups are approximately the ...
  • Popenko, N.; Ivanchenko, I.; Brovenko, I.; Zhigalov, A.; Karelin, S.; Gorbatyuk, I.; Ostapov, S.; Dremlyuzhenko, S.; Rarenko, I.; Zaplitnyi, R.; Fodchuk, I.; Deibuk, V.G. (Functional Materials, 2006)
    А novel semiconductor solid solution HgCdMnZnTe containing up to 5 % of manganese and zinc has been studied. Microhardness of these crystals and galvanomagnetic characteristics have been measured out as well as the X-ray ...
  • Gardner, B.J.; Parmenter, M.M. (Algebra and Discrete Mathematics, 2009)
    Directoid groups are 2-torsion-free abelian groups with an extra binary operation assigning upper bounds. They thus constitute a generalization of abelian l-groups and an equational substitute for directed abelian groups. ...
  • Nguyen Hoang Son; Vu Duc Thi (Algebra and Discrete Mathematics, 2019)
    The aim of this paper investigates some combinatorial characteristics of minimal key and antikey of closure operations. We also give effective algorithms finding minimal keys and antikeys of closure operations. We estimate ...
  • Umar, A. (Algebra and Discrete Mathematics, 2014)
    Let Xn = {1,2,…,n}. On a partial transformation α : Dom α ⊆ Xn → Im α ⊆ Xn of Xn the following parameters are defined: the breadth or width of α is ∣ Dom α ∣, the collapse of α is c(α) = ∣ ∪t∈Imα{tα⁻¹ :∣ tα⁻¹ ∣≥ 2} ∣, fix ...
  • Umar, A. (Algebra and Discrete Mathematics, 2010)
    Let Xn={1,2,⋯,n} and let α:Domα⊆Xn→Imα⊆Xn be a (partial) transformation on Xn. On a partial one-one mapping of Xn the following parameters are defined: the height of α is h(α)=|Imα|, the right [left] waist of α is ...
  • Dochviri, І. (Український математичний журнал, 2006)
    Some properties of regular and normal bitopological spaces are established. The classes of sets inheriting the bitopological properties of regularity and normality are found. A theorem on a finite covering of pairwise ...
  • Raji, A. (Algebra and Discrete Mathematics, 2021)
    In the present paper, we introduce the notion of *-generalized derivation in near-ring N and investigate some properties involving that of *-generalized derivation of a *-prime near-ring N which forces N to be a commutative ...
  • Borisenko, A.A.; Olin, E.A. (2007)
    We give upper and lower bounds for the ratio of the volume of metric ball to the area of metric sphere in Finsler-Hadamard manifolds with the pinched S-curvature. We apply these estimates to find the limit at infinity for ...
