The use of mass spectrometry to determine the position of the label in naphthalene-C13

Conclusions A mass spectrometric method was proposed for the determination of the position of the label in naphthalene-C¹³, based on its conversion to 1,4-naphthoquinone-C¹³ and the utilization of the peculiarities of the dissociation of the latter during electron impact.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 845–849, April, 1970.     

Low-molecular-weight mushroom metabolites V. Eburicoic acid fromPolyporus ailanthus

The triterpene acid isolated fromPolyporus ailanthus (Aphyllophorales) is identified as eburicoic acid on the basis of¹H and¹³C NMR, electron-impact mass, and IR spectra.S. Yu.

Numerical and Physical Modeling of the Circulation Flow in a Vortex Cell in the Wall of a Rectilinear Channel

The results of physical and numerical modeling of the three-dimensional vortex flow in a circular cell forming a recess in the wall of a rectangular constant-area channel are presented.     

Jucys-Murphy elements for Birman-Murakami-Wenzl algebras

The Burman-Wenzl-Murakami algebra, considered as the quotient of the braid group algebra, possesses the commutative set of Jucys-Murphy elements. We show that the set of Jucys-Murphy elements is maximal commutative for the generic Birman-Wenzl-Murakami algebra and reconstruct the representation theory of the tower of Birman-Wenzl-Murakami algebras.
