Optimal parameters of leader development in lightning
The dependences between the different parameters of a leader in lightning are obtained theoretically. The physical mechanism of the instability leading to the formation of the streamer zone is proposed. The instability has the wave nature and is caused by the self-influence effects of the space charge. Using a stability condition of the leader propagation, a dependence is obtained between the current across the leader head and its velocity of motion. The dependence of the streamer zone length on the gap length is also obtained. It is shown that the streamer zone length is saturated with the increasing of the gap length. A comparison between the obtained dependences and the experimental data is presented

The topic of borrowing in the Russian language remains a favorite object of study for both domestic and foreign linguists. This article presents the ways of penetration of lexical borrowings into Russian from different languages; identifies the areas of Anglicism using in modern Russian; considers loan words from the border areas on the example of Yakutian. Studies have shown that not only Russian has had a considerable impact on the languages of the indigenous peoples of the national republics, enriching them with new words. Also, the lexics of the Russian language itself has been subjected to a particular influence of national languages.Π’Π΅ΠΌΠ° Π·Π°ΠΈΠΌΡΡΠ²ΠΎΠ²Π°Π½ΠΈΠΉ Π² ΡΡΡΡΠΊΠΎΠΌ ΡΠ·ΡΠΊΠ΅ ΠΎΡΡΠ°Π΅ΡΡΡ ΠΈΠ·Π»ΡΠ±Π»Π΅Π½Π½ΡΠΌ ΠΎΠ±ΡΠ΅ΠΊΡΠΎΠΌ ΠΈΠ·ΡΡΠ΅Π½ΠΈΡ ΠΊΠ°ΠΊ Π΄Π»Ρ ΠΎΡΠ΅ΡΠ΅ΡΡΠ²Π΅Π½Π½ΡΡ

A Pulsational Model for the Orthogonal Polarization Modes in Radio Pulsars
In an earlier paper, we introduced a model for pulsars in which non-radial
oscillations of high spherical degree (\el) aligned to the magnetic axis of a
spinning neutron star were able to reproduce subpulses like those observed in
single-pulse measurements of pulsar intensity. The model did not address
polarization, which is an integral part of pulsar emission. Observations show
that many pulsars emit radio waves that appear to be the superposition of two
linearly polarized emission modes with orthogonal polarization angles. In this
paper, we extend our model to incorporate linear polarization. As before, we
propose that pulsational displacements of stellar material modulate the pulsar
emission, but now we apply this modulation to a linearly-polarized mode of
emission, as might be produced by curvature radiation. We further introduce a
second polarization mode, orthogonal to the first, that is modulated by
pulsational velocities. We combine these modes in superposition to model the
observed Stokes parameters in radio pulsars.Comment: 19 pages, 4 figures accepted Ap

The article considers an approach to a formalized description and meaning harmonization for financial terms and means of semantic modeling. Ontologies for the semantic models are described with the help of special languages developed for the Semantic Web. Results of FIBO application to solution of different tasks in the Russian financial sector are given
Preparation and characterization of Bi26β2xMn2xMo10O69-d and Bi26.4Mn0.6Mo10β2yMe2yO69-d(Me = V, Fe) solid solutions
Received: 06.06.2017; accepted: 23.06.2017; published: 14.07.2017.Single phase samples of bismuth molybdate, Bi26Mo10O69, doped with Mn on the bismuth sublattice and V, Fe on the molybdenum sublattice were found to crystallize in the triclinic Bi26Mo10O69 structure at low doping levels and in the monoclinic Bi26Mo10O69 structure - at higher dopant concentration. The assumption that all Mn ions have an oxidation state of +2 was confirmed by means of magnetic measurement results analysis using Curie-Weiss law. Conductivity was investigated using impedance spectroscopy. The conductivity of Bi26.4Mn0.6Mo9.6Fe0.4O69-d was 1.2*10-2 S*cm-1 at 973 K and 2.2*10-4 S*cm-1 at 623 K, and the conductivity of Bi26.4Mn0.6Mo9.2V0.8O69-d was 2.2*10-3 S*cm-1 at 973 K and 2.2*10-5 S*cm-1 at 623 K
