    Exact theory of the (Einstein) gravitational field in an arbitrary background space-time (1984)
    Springer
    Communications in mathematical physics 94 (1984), S. 379-396

    Topics: Mathematics , Physics
    Notes: Abstract The Lagrangian based theory of the gravitational field and its sources at the arbitrary background space-time is developed. The equations of motion and the energy-momentum tensor of the gravitational field are derived by applying the variational principle. The gauge symmetries of the theory and the associated conservation laws are investigated. Some properties of the energymomentum tensor of the gravitational field are described in detail and the examples of its application are given. The desire to have the total energymomentum tensor as a source for the linear part of the gravitational field leads to the universal coupling of gravity with other fields (as well as to the self-interaction) and finally to the Einstein theory.

    Relation between T c and the defect structure of neodymium cerium cuprite Nd2−x CexCuO4−y (1998)
    Springer
    Physics of the solid state 40 (1998), S. 157-162

    Topics: Physics
    Notes: Abstract Neutron powder diffraction has been used to study the defect structure of neodymium cerium cuprite Nd2−x CexCuO4±y (x=0.15). It has been shown that in addition to oxygen vacancies, O2 sites in superconducting samples may also contain a small quantity of implanted oxygen atoms positioned between copper ions and neodymium/cerium, which control the electrical charge in the Cu-O planes. The oxygen distribution among crystal lattice sites in Nd2−x CexCuO4±y (x=0.15) as determined, the average charge of the copper ions was calculated by the method of valence sums, and a correlation was established between the charge of the copper-oxygen plane and T c.

    Ferro-and antiferromagnetic ordering in LaMnO3+δ (1999)
    Springer
    Physics of the solid state 41 (1999), S. 91-96 
    Details
    ISSN: 1063-7834
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A neutron diffraction study of the crystalline structure and magnetic state of LaMnO3+δ samples with different deviations from oxygen stoichiometry has been made at 4.2 K. It is shown that annealing at reduced oxygen pressure is accompanied by transformation of the magnetic structure from ferromagnetic, with magnetic moments parallel to the b axis, to antiferromagnetic, with the wave vector k=0 and the moments along the a axis (space group Pnma). A comparison of experimental with expected Mn ion moments suggests that magnetic order does not extend throughout the sample volume. Part of the Mn ions form magnetic clusters ∼20 Å in size.

    Mechanism of noradrenalin liberation from the rat brain under the influence of nicotine (1975)
    Springer
    Bulletin of experimental biology and medicine 80 (1975), S. 900-902

    Notes: Abstract Definite relationships were found between the noradrenalin concentration and Mg++-ATPase activity in the rat brain during the action of nicotine. It is suggested that Mg++-ATPase regulates the storage of noradrenalin in the tissue depots.

    Effect of nicotine on noradrenalin content in the rat brain (1975)
    Springer
    Bulletin of experimental biology and medicine 79 (1975), S. 147-150 
    Details
    ISSN: 1573-8221
    Keywords: rat brain ; noradrenalin and its content ; nicotine and its effect on the CNS
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract In doses of 0.4 and 4 mg/kg nicotine reduced the noradrenalin (NA) content in the rat brain for 2 h. The greatest decrease in NA was observed in the period of hyperkinesia evoked by nicotine in a dose of 4 mg/kg. A further injection of the same dose of nicotine 30 min later did not give rise to hyperkinesia and did not induce, any further decrease in NA. In a dose of 4 mg/kg given 4 and 20 h after reserpine (5mg/kg) nicotine reduced the NA level and caused the appearance of hyperkinesia. Injection of nicotine (4 mg/kg) 25 min after amphetamine (5 mg/kg) did not significantly lower the NA level. Liberation of NA in the brain tissues is evidently an important central effect of nicotine and it shares a common mechanism with the effect of amphetamine.

    Distribution of the adrenoblocking drug pyrroxan in albino rats (1976)
    Springer
    Bulletin of experimental biology and medicine 82 (1976), S. 1815-1816 
    Details
    ISSN: 1573-8221
    Keywords: adrenoblockers ; pyrroxan ; distribution ; hypothalamus
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract The distribution of the adrenoblocking drug pyrroxan in the blood plasma and organs of albino rats was investigated. Pyrroxan was shown to appear rapidly in the brain, liver, kidneys, and other organs and to accumulate selectively in the hypothalamus. The use of a spectrofluorometric method showed that unchanged pyrroxan molecules disappear from the plasma and organs in the course of 2 h. In studies with pyrroxan-14C, radioactivity was detected in the organs for 24 h, but in the plasma for several days, indicating the formation of metabolites of pyrroxan or its complexes with plasma proteins and with structural elements of the organs. The high effectiveness of pyrroxan in different forms of hypothalamic disturbances accompanied by symptoms of overexcitation of the sympathetic nervous system can be explained by its selective accumulation in the hypothalamus.

    Effect of benactyzine and arecoline on Na,K-ATPase activity and content of Na+ and K+ ions in the rat brain (1977)
    Springer
    Bulletin of experimental biology and medicine 83 (1977), S. 185-187 
    Details
    ISSN: 1573-8221
    Keywords: Na,K-ATPase ; electrolytes ; arecoline ; benactyzine ; rat brain
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract Activity of Na,K-ATPase and the content of Na+ and K+ ions in the rat brain were studied after administration of arecoline and benactyzine. Both drugs increased Na,K-ATPase activity, possibly on account of changes in the redistribution of Na+ and K+ ions in the nerve cell. Arecoline was shown to cause changes in the distribution of electrolytes characteristic of depolarization, and benactyzine changes characteristic of hyperpolarization of the nerve cell membrane.
