COMMUNICATIONS OF THE MOSCOW MATHEMATICAL SOCIETY: A test for non-compactness of the foliation of a Morse form
In this paper we study foliations determined by a closed 1-form with Morse singularities on smooth compact manifolds. The problem of the topological structure of the level surfaces of such forms wasExpand
[Mathevolepis junlanae sp. n. (Cyclophyllidea: Hymenolepididae: Ditestolepidini), a new cestode species from shrews of Far East].
Mathevolepis junlanae sp. n. from shrews (Sorex spp.) of Far East is described given. The new species occupies an intermediate position between the Palaearctic species M. petrotschenkoi Spassky, 1948Expand
Determination of rhenium in gold-containing ores by X-ray fluorescence spectrometry
A procedure is developed for determining rhenium in gold-containing ores by X-ray fluorescence spectrometry. The adsorption preconcentration of perrhenate ions on activated charcoal is studied. It isExpand
Reaction of halo-sym-triazines with N-alkylhydroxylamines
The reaction of 2-chloro-4-methoxy-(benzyloxy, methylthio)-6-alkylamino-sym-triazines with N-alkylhydroxylamine to give the corresponding N-alkylhydroxylamino derivatives of sym-triazine has beenExpand
Noncompact leaves of foliations of Morse forms
In this paper foliations determined by Morse forms on compact manifolds are considered. An inequality involving the number of connected components of the set formed by noncompact leaves, the numberExpand
Herbicidal hydroxylamine derivatives
The synthesis of 2-alkyl(dialkyl)amino-4-chloro-sym-triazine derivatives of hydroxylamine, N-methylhydroxylamine, and N-phenylhydroxylamine has been effected and their properties have been studied.Expand
Herbicidal hydroxylamine derivatives
The energies of intermolecular hydrogen bonding for eight amino derivatives of sym-triazines were obtained from the temperature dependence of the equilibrium constants, which were determined byExpand
[Spasskylepis tiunovi sp. n. (Cyclophyllidea, Hymenolepididae)--a new cestode species from shrews of the Far East].
The description of a new cestode species with a serial homonomous strobila, Spasskylepis tiunovisp. n. (Cyclophyllidea, Hymenolepididae, Ditestolepidini) from shrews (Sorex spp.) of the Far East isExpand
