Projective lattices of tiled orders
No full textTiled orders over discrete valuation ring have been studied since the 1970s by many mathematicians, in particular, by Yategaonkar V.A., Tarsy R.B., Roggenkamp K.W, Simson D., Drozd Y.A., Zavadsky A.G. and Kirichenko V.V. Yategaonkar V.A. proved that for every n > 2, there is, up to an isomorphism, a finite number of tiled orders over a discrete valuation ring O of finite global dimension which lie in where K is a field of fractions of a commutatively discrete valuation ring O. The articles by R.B. Tarsy, V.A. Yategaonkar, H. Fujita, W. Rump and others are devoted to the study of the global dimension of tiled orders. H. Fujita described the reduced tiled orders in Mn(D) of finite global dimension for n = 4; 5. V.M. Zhuravlev and D.V. Zhuravlev described reduced tiled orders in Mn(D) of finite global dimension for n = 6: This paper examines the necessary condition for the finiteness of the global dimension of the tile order. Let A be a tiled order. The kernel of the projective resolvent of an irreducible lattice has the form M1f1 +M2f2 + ::: +Msfs, where Mi is irreducible lattice, fi is some vector. If the tile order has a finite global dimension, then there is a projective lattice that is the intersection of projective lattices. This condition is the one explored in the paper.Key words: tiled order, exponent matrix, projective lattice.Pages of the article in the issue: 16-19Language of the article: UkrainianTiled orders over discrete valuation ring have been studied since the 1970s by many mathematicians, in particular, by Yategaonkar V.A., Tarsy R.B., Roggenkamp K.W, Simson D., Drozd Y.A., Zavadsky A.G. and Kirichenko V.V.

A new species of the conodont genus Siphonodella Branson & Mehl (late Tournaisian)
No full textA new upper Tournaisian (Lower Carboniferous) siphonodellid conodont species Siphonodella carinata n. sp. is described. The material comes from the shallow-water carbonate sediments of the Pechora Swell (Timan-Pechora region or NE of European Russia). The co-occurrence of conodonts Hindeodus cristulus (Youngquist & Miller), Bispathodus stabilis (Branson & Mehl) Morphotype 1, Polygnathus longiposticus Branson & Mehl and Pseudopolygnathus nodomarginatus (Branson) suggests the late Tournaisian (Lower Siphonodella crenulata Zone) age of the deposits. Morphologically the new species is similar to Siphonodella semichatovae Kononova & Lipnjagov and S. ludmilae Zhuravlev & Plotitsyn, but differs in possessing three rostral ridges at the late stages of ontogeny and Class III symmetry. The presence of the shallow-water siphonodellids Siphonodella bella Kononova & Migdisova and S. quasinuda Gagiev, Kononova & Pazuhin in the upper part of the Tournaisian is detected for the first time
Nasledie «Sidora Karpovicha» v sovremennoj pesennoj kul'ture
No full textThe article analyzes the transformation of the Russian folk song “Dear
Sir Sidor Karpovich”, studied by V. N. Toporov in 1979. This text was a
prison game depicting a funeral rite and having a function of initiation,
but re cently it has become a popular song and lost its minor mood. At the
same time, the protagonist (Sidor Karpovich) loses his name and becomes
a secondary character. The main role is taken by his wife, Lyubka, called
by the epithet “gray dove”. The plot of the song is based on twists and turns of her life after the death of her husband. Analyzing the image of the dove in poetry and, in particular, in prison lyrics, as well as looking at possible influences of other popular songs, the author proposes possible reasons for such a transformation

rbcL and rpoL gene sequences of Panax vietnamensis var. fuscidiscus and Panax vietnamensis, the background for identification and comparison
No full textThe Panax vietnamensis var. fuscidiscus samples collected at Phong Tho district, Lai Chau Province have morphological characteristics very similar with those of Panax vietnamensis distributed in Ngoc Linh mountain at Quang Nam and Kon Tum provinces that hinders the identification of these taxons. To supply the information to identify two species and know the genetic distance of these species with other Panax species, we sequenced rbcL and rpoB genes that are among DNA barcoding markers recommended for plant species identification. In the rbcL gene of 700 bp in length, we found 9 nucleotide differences between Panax vietnamensis var. fuscidiscus and Panax vietnamensis and the genetic similarity was 98,8%, while in the rpoB gene of 500 bp in length, only 2 nucleotide differences were discovered and the genetic distance was 0,4%. The sequences of rbcL and rpoB of Panax vietnamensis var. fuscidiscus and Panax vietnamensis were submitted to Genbank with the accession numbers KT194325.1, KT194324.1 and KT154685.1, KT154686.1 respectively.

Broadening of the superconducting transition by fluctuations in three-dimensional metals at high magnetic fields
No full textThe Bragg-chain model of the two-dimensional (2D) vortex state at high magnetic field [V. N. Zhuravlev and T. Maniv, Phys. Rev. B 60, 4277 (1999)] is extended to an array of coupled superconducting (SC) layers. Application to MgB2 and YNi2B2C yields good quantitative agreement with high-field magnetization measurements, indicating that the smeared transitions observed in these materials are, at least in great part, due to SC fluctuations. Similar to the situation in a 2D system, the melting of the vortex lattice in strongly coupled SC layers is predicted to occur well below the mean field H-c2.This article is published as Maniv, T., V. Zhuravlev, J. Wosnitza, O. Ignatchik, B. Bergk, and P. C. Canfield. "Broadening of the superconducting transition by fluctuations in three-dimensional metals at high magnetic fields."
