    Experimental research on specific volumes of rubidium and potassium vapors (1987)
    Springer
    International journal of thermophysics 8 (1987), S. 239-246 
    Details
    ISSN: 1572-9567
    Keywords: dosing device ; piezometer ; potassium ; PVT measurements ; rubidium ; specific volume ; superheated vapor
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Results are reported of an experimental study of superheated rubidium vapor in the temperature range 1450–2000 K and pressure range 1.7–5.2 MPa and potassium in the range 1500–2100 K and 1.4–4.0 MPa. The experiments have been performed with an apparatus adaoted to implement a modified constant-volume piezometer technique, where the sensing element of a pressure transducer represented by a diaphragm is placed in a low-temperature zone. A dosing device is described which permits the performance of accurate measurements of the mass of the metal in the piezometer chamber. The present results are in good agreement with those reported by other investigators in the overlaping temperature and pressure ranges.

    Fertilization and cleavage of the human ovumin vitro (1976)
    Springer
    Bulletin of experimental biology and medicine 81 (1976), S. 451-453 
    Details
    ISSN: 1573-8221
    Keywords: human ovum ; fertilization and development in vitro
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract A method of cultivating and fertilizing human ova obtained from ovaries removed at operation is described. A special method of sampling active spermatozoa was used for fertilization. Zygote formation was observed 24–36 h after fertilization of the ripe ova, an embryo of the two-cell stage was formed after 36–40 h, and an embryo at the four-cell stage after 48 h. The number of blastomeres reached 8 after 60–64 h, and after approximately 100–120 h the embryos reached the morula stage. The results provide wide scope for the study of the physiology and pathology of early human embryonic development.

    Dipole moments of the carbonyl groups in cyclic β-diketones from IR spectroscopy data (1995)
    Springer
    Russian chemical bulletin 44 (1995), S. 670-677 
    Details
    ISSN: 1573-9171
    Keywords: IR spectroscopy ; dipole moments ; coplanar arrangement ; carbonyl groups ; 2-arylindan-1,3-diones
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The αCO angles between the carbonyl groups and the dipole moments of a number of 2-arylindan-1,3-diones were determined from the data of IR spectroscopy. The effects of substituents on αCO depending on their positions and inductive factors were found. It was established that the interaction between the vibrations of the carbonyl groups depends on both the αCO angle or the ΣμCO dipole moment and the coplanar arrangement of these groups.
