On the problem of synthesis of superheavy nuclei. A short historical review on first theoretical predictions and new experimental reality

It is shown that it is just Dubna that possesses the priority both in the recent synthesis of a superheavy nucleus with charge Z = 114 (Flerov Laboratory of Nuclear Reactions, JINR) and in its theoretical prediction (Bogoliubov Laboratory of Theoretical Physics, JINR) made 33 years ago. Possible sizes of the island of stability of superheavy nuclei are discussed.Comment: LaTeX, 6 page

Synthesis of Superheavy elements and Theory of Atomic Nucleus

The connection of synthesis of long-lived superheavy nuclei and existence of the island of stability with the choice of realistic nuclear potential is discussed: the behaviour of the average field of nuclei is an important element of nuclear models. It is also shown that it is just Dubna that possesses the priority both in the recent synthesis of a superheavy nucleus with charge Z=114 and in its theoretical prediction made 35 years ago. Possible sizes of the island of stability of superheavy nuclei are considered.Comment: 14 pages . Talk at the Intern.Symp.on Exotic Nuclei . Baikal Lake, July 24 -- 28, 200

Theory of constraints in value based cost management

This article highlights the problem of setting value-focused cost management and implementation of Theory of Constraints in enterprise management. To do this, analysis statements of theory of constraints within the concept of relevance is made and pre-requisites for implementation of such statements are formulated. From the perspective of the value-based management, business process optimization mechanism is analyzed and an alternative model for calculating relevant costs is proposed. This study was made on the example of oil fields development process. © IDOSI Publications, 2013

Continued fraction representation of the Coulomb Green's operator and unified description of bound, resonant and scattering states

If a quantum mechanical Hamiltonian has an infinite symmetric tridiagonal (Jacobi) matrix form in some discrete Hilbert-space basis representation, then its Green's operator can be constructed in terms of a continued fraction. As an illustrative example we discuss the Coulomb Green's operator in Coulomb-Sturmian basis representation. Based on this representation, a quantum mechanical approximation method for solving Lippmann-Schwinger integral equations can be established, which is equally applicable for bound-, resonant- and scattering-state problems with free and Coulombic asymptotics as well. The performance of this technique is illustrated with a detailed investigation of a nuclear potential describing the interaction of two $\alpha$ particles.Comment: 7 pages, 4 ps figures, revised versio

Nuclear Scissors Mode with Pairing

The coupled dynamics of the scissors mode and the isovector giant quadrupole resonance are studied using a generalized Wigner function moments method taking into account pair correlations. Equations of motion for angular momentum, quadrupole moment and other relevant collective variables are derived on the basis of the time dependent Hartree-Fock-Bogoliubov equations. Analytical expressions for energy centroids and transitions probabilities are found for the harmonic oscillator model with the quadrupole-quadrupole residual interaction and monopole pairing force. Deformation dependences of energies and $B(M1)$ values are correctly reproduced. The inclusion of pair correlations leads to a drastic improvement in the description of qualitative and quantitative characteristics of the scissors mode.Comment: 36 pages, 5 figures, the results of calculation by another method and the section concerning currents are adde

Urzhumian stage in geochemical variations

Geological site Cheremushka is known as key stratigraphic record of Urzhumian stage of Middle Permian (Biarmian) series. It is situated on the Volga River's right bank, near Kazan city (Russia). In present paper lithology and geochemistry of this section is analyzed by EDXRF and discussed to reveal regional facial and cyclic features of the succession formed in altered sedimentary environments. Bulk geochemistry of sediments can be used to characterize the distribution of allogenic and authigenic components. It can also be used to compare these distributions with the general evolutionary stages of Volga River's region. The sedimentary sequence at site Cheremushka is divided into nine geochemical stages and sedimentary cycles using bulk geochemistry profiles, where silica change is considered as basic. The stage (cycles) boundaries correlate with the significant lithologic boundaries. Paleoenvironmental evolution is interpreted as alteration of lagoon and terrigenous flux influenced environments in arid climate during Sulitzkian time and in humid climate during Isheevskian time. © 2006-2014 Asian Research Publishing Network (ARPN)
