The aim of the study was to develop and validate an express procedure for the isolation and quantification of water-soluble polysaccharides from high devisyl roots (Ínula helenium L.). In order to accelerate the process of extracting biologically ac

Published and original data on the steppe viper distribution in the Central Chernozem Region, including the museum-reserve Divnogorie, were generalized for the period of 2012 to 2016. The sex and age composition of vipers as well as their morphologic

This paper describes a method for estimating of disturbances development and the laminar-turbulent transition location on a base of the linear stability theory in presence of the acoustic field. In a stable region amplitudes of perturbation velocitie

New data about the morphology of Nikolsky’s viper (Vipera berus nikolskii Vedmederja, Grubant et Rudaeva, 1986) were summarized for 2008–2014. Average values of metric features and data of scalation were defined. Sexual dimorphism is observed on

On the basis of resonance theory the possibility of the longitudinal structures generation was fixed in the compressible boundary layer by an external vorticity. It takes place under a condition when parameters of externally vortex wave become the cl

Present paper is devoted to those acoustical problems which are also related to the problem of the turbulence onset in high-speed boundary layers. Basic equations governing linear development of both hydrodynamic and acoustic waves in high-speed boun

In linear and nonlinear approach (weakly nonlinear theory of stability) interaction of disturbances on a boundary layer of compressed gas is considered at surface cooling. The regimes of moderate (Max number М = 2) and high (М = 5.35) are considere
