Growth and spectroscopic investigations of new crystal Er(3+),Ce(3+) : NaLa(MoO(4))(2) promising for 1.5 mu m solid-state lasers
No full textScheelite-like disordered double sodium-lanthanum molybdate NaLa(MoO(4))(2) single crystals co-doped with Er(3+) and different concentrations of Ce(3+) have been grown by Czochralski technique. The 300K spectroscopic properties of the excited states (4)S(3/2), (4)I(11/2) and (4)I(13/2) of Er(3+) ions in grown crystals as a function of Cerium concentration have been investigated. The lifetime of (4)I(11/2) have been found to reduce from 130 mu s in the solely Er-doped sample to approximately 3.5 mu s, when the concentration of Ce reaches 50 at. %. At the same time the lifetime of (4)I(13/2) level at 300 K remains unchanged (3.7 ms) up to the concentration of Ce in crystal equal to 10 at. %, and reduces by less than 30% (2.6 ms) in the 50 at. % Ce co-doped sample. This result looks very promising from point of view of obtaining low-threshold 1.5 mu m laser oscillation

The practical part is devoted to the processing of a particular business plan, which is prepared according to bank's criterions and demonstrates that the project is viable and has a chance of success
Lyrický hrdina v sovětských bardovských písních (60. - 80. léta 20. století)
No full text(in English) The purpose of this work is to analyze the figure of the lyrical hero in the work of Russian- speaking bard poets, to determine the means of artistic expression that form the image of the lyrical hero, to systematize these images and to attempt to determine their archetypes. Main representatives - V. Vysotskij, B. Okudzhava, Y. Vizbor. We consider an equally important aspect of the research to be the study of the connections between the lyrical hero of a bard's song and Soviet reality: of scientific interest are the relationships between literary art, free from censorship and ideology, created by representatives of the intelligentsia of a totalitarian ideologized state, as well as its target audience, which can be directly or indirectly identified with the lyrical hero.(česky) Cílem této práce je analyzovat postavu lyrického hrdiny v dílech ruskojazyčných básníků-bardů 60. - 80. let 20. století, určit prostředky uměleckého vyjádření, které tvoří obraz lyrického hrdiny, systematizovat tyto obrazy a pokusit se určit jejich archetypy. Hlavními představiteli jsou V. Vysockij, B. Okudžava, Ju. Vizbor. Za neméně důležitý aspekt studie považujeme studium souvislostí lyrického hrdiny bardovské písně se sovětskou realitou: vědecky zajímavé jsou vztahy mezi necenzurovaným a ideologickým literárním uměním vytvořeným představiteli inteligence totalitního ideologického státu, jakož i jeho cílovou skupinou, kterou lze s lyrickým hrdinou přímo či nepřímo ztotožnit.Institute of East European StudiesÚstav východoevropských studiíFilozofická fakultaFaculty of Art
COMPRESSIBILITY OF MICROPOROUS MATERIALS WITH CHA TOPOLOGY: 2. ALPO-34.
No full textThe HP behavior of ALPO-34 as-synthesized was investigated by means of in-situ synchrotron X-ray powder diffraction, in the frame of a wider project aimed at understanding the role of the framework/extraframework content in the P-induced deformation mechanisms of natural and synthetic microporous materials with CHA framework topology. ALPO-34 compressibility under non-penetrating P transmitting medium was determined up to 6.0 GPa and upon decompression to Pamb. After an initial large structure deformation at P < 0.4 GPa, a regular volume reduction was observed up to about 3 GPa. Above 3.1 GPa, an abrupt
change in the behavior of all cell parameters was observed,
accompanied by an evident decrease in compressibility. The
isothermal Equation of State (EoS), refined with a II-order
Birch–Murnaghan EoS from 0.4 to 3.1 GPa, yielded the following
parameters: V0 1⁄4 755(1)A ̊ 3, K0 1⁄4 54(3) GPa. No
complete X-ray amorphization was achieved up to the highest
investigated P value. A complete reversibility of the unit
cell parameters was observed upon P release. The compressibility
behavior of ALPO-34 was compared with that of the
other CHA-type zeolites. The volume reduction observed for
natural chabazite, and for SAPO-34 and ALPO-34 assynthesized,
was 6.2%, 9.4%, and 6.0%, respectively. Notwithstanding
the presence of morpholine molecules, as a structure directing agent, in the two as-synthesized phases, they exhibited significantly different compressibility. This can be interpreted as due to the octahedral coordination of part of the ALPO-34 framework aluminum, leading to a more rigid framework compared to that of SAPO-34, which contains only tetrahedral aluminum

Exact static solutions for discrete ϕ4 models free of the Peierls-Nabarro barrier: Discretized first-integral approach
No full textThis is the pre-published version harvested from arXiv. The published version is located at http://pre.aps.org/abstract/PRE/v74/i4/e046609We propose a generalization of the discrete Klein-Gordon models free of the Peierls-Nabarro barrier derived in Spreight [Nonlinearity 12, 1373 (1999)] and Barashenkov et al. [Phys. Rev. E 72, 035602(R) (2005)], such that they support not only kinks but a one-parameter set of exact static solutions. These solutions can be obtained iteratively from a two-point nonlinear map whose role is played by the discretized first integral of the static Klein-Gordon field, as suggested by Dmitriev et al. [J. Phys. A 38, 7617 (2005)]. We then discuss some discrete ϕ4 models free of the Peierls-Nabarro barrier and identify for them the full space of available static solutions, including those derived recently by Cooper et al. [Phys. Rev. E 72, 036605 (2005)] but not limited to them. These findings are also relevant to standing wave solutions of discrete nonlinear Schrödinger models. We also study stability of the obtained solutions. As an interesting aside, we derive the list of solutions to the continuum ϕ4 equation that fill the entire two-dimensional space of parameters obtained as the continuum limit of the corresponding space of the discrete models

Tekhnol. 2017. V. 60. N 1. P. 45-49. In this work crystal data of bis[1-(diaminomethylene)-thiouron-1-ium] sulfate is shown. This compound was characterized by IR spectroscopy and elemental analysis. The monocrystal of this compound was obtained and the structure was confirmed by single X-ray analysis. Moreover, the work describes potential application of synthesized compound. Comparative characteristics of thiourea and its known salts are demonstrated. It is known, that derivatives of thiourea have several tautomeric forms, which can be different in crystalline state or in solution. Therefore, changed scheme of the synthesis of 2-imino-4-thiobiuret is proposed. Elemental cell of crystal consists of two 1-(diaminomethylene)thiouron-1-ium cations and one sulfat anion. A full set of X-ray diffraction data was deposited in the Cambridge Structural Database (deposit CCDC 1421710) and it can be gotten from the site www.ccdc.cam.ac.uk/data_request/cif.</jats:p
Increasing Trust in Banking and Developing Insurance System for Bank Deposits in Russia
No full textIn this article the topical issues connected with changes are considered, occurring in the banking sector of Russia, the number of the operating credit organizations caused by essential reduction, intensive revocation of licenses on bank activity at the credit organizations Bank of Russia. According to the author, in this regard there is a number of the problems connected with sufficiency of a network of the operating credit organizations of requirement of ensuring economic growth, formation of the healthy competitive environment, sufficiency of Fund of insurance of deposits for providing guarantees to investors in case of bankruptcy of banks. In article, recent trends of insurance of deposits in the countries of EEC and the USA are considered. Taking into account the revealed tendencies problems of functioning of system of insurance of deposits of citizens in the Russian commercial banks are analyzed. To number of such problems are carried: insufficient volume of an insurance covering; concentration of deposits mainly in the large banks which are on the one hand, carriers of system risk, with another, - in which capitals participates the state, having thus subsidiary responsibility; limited set of functions of Agency and some other. Taking into account the carried-out analysis and an assessment of operating system of insurance of deposits it is offered: to develop the mechanism of overcoming of "moral" risk; increase of financial literacy of the population, in view of activity of some banks on advance in a segment of private investors of the products which aren't covered by system of guaranteeing; to define introduction of the mechanism of differentiation of contributions to the ASV insurance Fund depending on degree of riskiness of activity of participating bank of system, system modernization risk - the focused supervision as bases of stable functioning of the banking sector and its hotel institutes

Summary
The article presented data regarding the average mesiodistal, vestibulо-oral and vertical dimensions of the teeth of boys and girls fromUkraine, obtained using cone beam computed tomography. We have studied 101 tomograms, male (n = 44) and female (n = 57) between the ages from 18 to 25 years with orthognathic bite. For this investigation we used dental cone beam computer tomography - Veraviewepocs 3D, Morita. When comparing the performance of odontometric features of the similar teeth from right and left sides, no significant differences were found. Established population characteristics for mesiodistal, vestibulo-oral and vertical dimensions of the teeth for the boys and girls fromUkrainewith orthognathic bite. For most sizes of teeth (except mesiodistal size of the second lower premolar) showed significant differences (larger sizes in boys).
Key words: odontometry, computed tomography, the size of the teeth.
