Self-Adjointness of Generalized MIC-Kepler System

We have studied the self-adjointness of generalized MIC-Kepler Hamiltonian, obtained from the formally self-adjoint generalized MIC-Kepler Hamiltonian. We have shown that for \tilde l=0, the system admits a 1-parameter family of self-adjoint extensions and for \tilde l \neq 0 but \tilde l <{1/2}, it has also a 1-parameter family of self-adjoint extensions.Comment: 11 pages, Latex, no figur

Система распределения обязанностей по государственной и общественной поддержки издательско-книготорговой отрасли Украины

Сприяння це, перш за все, увага як державних установ так і громадських організацій. В статті систематизована інформація про функціонуючі, на даний момент, організації, що підтримують ВПК України, а такою класифікована інформація щодо функцій, які виконують дані організації.Every sector of Economy needs assistance and attention of Public as well as Private sector organizations. Publishing and Bookselling sectors are not exceptions. Unfortunately, as these activities require monetary and legislative support due to peculiarity of Book as a market product, in case of ignoring, its activity is pointless. In this article author reveals information about up-to-date state of Ukrainian Publishing and Bookselling sectors in terms of organizations which are active and support this sector. Information about their creation, functions which these organizations implement and about areas of activity is classified. The most important disadvantages and aspects which require Government attention are specified.Содействие – это, в первую очередь, внимание как государственных учреждений, так и общественных организаций. В статье систематизирована информация о функционирующих, на данный момент, организациях, оказывающих поддержку ИПК Украины, а также классифицирована информация о функциях, которые выполняют данные организации

Gunn Oscillators Based on Shielded Dielectric Resonators with Mechanical Frequency Tuning

The features of Gunn oscillators based on shielded dielectric resonators with whispering gallery modes and ray oscillations are investigated. Their comparative analysis for oscillators with different dielectric resonant structures is carried out

Vertical Structure of the Milky Way Disk with Gaia DR3

Using a complete sample of about 330,000 dwarf stars, well measured by Gaia DR3, limited to the galactic north and south solid angles (Formula presented.) and up to a vertical distance of 2 kpc, we analyze the vertical structure of the Milky Way stellar disks, based on projected tangential velocities. From selected subsamples dominated by their corresponding population, we obtain the thin and thick disk scale heights as (Formula presented.) pc and (Formula presented.) pc, respectively. Then from the simultaneous fitting of the sum of two populations over the whole sample, assuming these scale heights, we estimate the thick-to-thin disk number density ratio at the galactic plane to be (Formula presented.), which is consistent with a previous result by the authors: in the galactic plane there is a significant number of thick disk stars, possibly as many as thin disk ones, which also points to the existence of more thick disk stars than generally thought. The overall fit does not closely follow the data for (Formula presented.) pc and points to the presence of more stars beyond the thin disk that cannot be accounted for by the two-disk model

VALUE CONCEPTS OF "ACCOUNTING POLICY" AND "BALANCE SHEET POLICY"

The article considers the justification of its own theoretical approaches to accounting and balance policy on the basis of legal, scientific, and theoretical positions of their organization and proposes author definitions of the terms "accounting policy" and "balance policy".The authors prove that the concept of "accounting" and "balance" policy coincides in part, at least in the word "politics". Although the content of these concepts covers common elements, we argue that each of these concepts also includes components that are not elements of another concept. It is stressed that these concepts can not be identified in any way.The article considers the justification of its own theoretical approaches to accounting and balance policy on the basis of legal, scientific, and theoretical positions of their organization and proposes author definitions of the terms "accounting policy" and "balance policy".The authors prove that the concept of "accounting" and "balance" policy coincides in part, at least in the word "politics".

Application of a superparametric finite shell element to the calculation of turbine blade vibrations

Determination of the natural frequencies and forms of vibrations of turbine blades with the present level of knowledge is one of the chief problems that have to be solved at the design stage of turbines in order to ensure vibration reliability. Greater possibilities of devising more correct mathematical models of blades and universal methods of investigating their vibrations are opened up in connection with the application of the finite element method.Для расчета колебаний лопаток турбомашин сложной геометрии используют суперпараметрические оболочечные конечные элементы
