Sixty Year's Experience in Operating the Rybinsk Reservoir

The social and economic role of the Rybinsk Reservoir is assessed, and its hydrological, hydrophysical, and hydrochemical features are characterized. The reservoir biota formation is described and its potential for fishery is determined. The attitude of the state structures and the community toward the reservoir in different periods of its existence is discussed.     

Impact of Reservoirs on the Fauna

The main forms of the impact of man-made lakes on terrestrial fauna populations and communities are considered. Peculiarities of the effect of man-made lakes on zoocomplexes in the upper and lower pools of hydraulic structures are analyzed. Approaches to developing measures aimed at decreasing environmental damage caused by reservoir construction are substantiated.

Role of a scalar field in the radiation dominated epoch of the development of the universe

The recently discovered accelerated expansion of the universe is of current interest in theoretical research on the evolution of the universe. The cause of this behavior is presumably the presence of dark energy, which has been estimated to form up to 70% of the universe and generates a “repulsive force.” In this paper a cosmological model is constructed which takes the dark energy into account in a Jordan-Brans-Dicke tensor-scalar model with a dominant, nonminimally coupled scalar field in the presence of a cosmological scalar. The radiation dominant epoch is discussed. __________ Translated from Astrofizika, Vol. 51, No. 1, pp. 151–159 (February 2008).
