    Notes: Abstract Theoretical and experimental aspects of the production, transformation, diffusion and loss of N2 in the upper atmosphere are considered. The N2-CO2 near-resonant system in theD andE regions is taken into account. We describe our understanding of the methods necessary to find the vibrational populations of N2 and CO2 (asymmetric mode of CO2). The calculations of the vibrational temperatures in theD, E, andF regions for the mid-latitude ionosphere and an aurora are presented. The connection between the excited species and the 4.26-μm radiation intensities is considered. The models for the rate coefficient of the reaction of O+ with N2 and the electron density decrease resulting from N2 in the F region are discussed.

    Notes: Abstract In this paper we present the results of a study of the electron cooling rate, the production rates of vibrationally excited N2(v), and the production frequency of the N2 vibrational quanta arising from the collisions of electrons with unexcited N2(0) and vibrationally excited N2(1) molecules as functions of the electron temperature. The electron energy transfer rates for vibrational excitation of N2 have been calculated and fit to analytical expressions by use of the revised vibrationally excited N2 cross sections. These new analytical expressions are available to the researcher for quick reference and accurate computer modeling with a minimum of calculations.

    Notes: Abstract Repair processes in the liver and adrenal cortex of hemiadrenalectomized female rats with an acute disturbance of the circulation resulting from orthostasis were studied by quantitative methods (cytometry, karyometry, nucleolometry, determination of the cell composition and of the nucleo-cytoplasmic and nucleolo-nuclear ratios). Regeneration of the organs studied showed some common features. During the first days after the experiment the number of dying cells in the organs was increased. Meanwhile the number of amitoses and of binuclear cells increased in the liver. By the 15th day in the adrenal and by the 45th day in the liver the cell composition of the organs was stabilized. During the first week after orthostasis mitotic activity of the epithelial cells was increased in both organs. In the later stages regeneration took place at the intracellular level (activation of the nuclear apparatus and hypertrophy of the cytoplasm of the cells).
