Data of long-term measurements of under-ice solar radiation, water temperature, and chlorophyll a are analyzed in four phytoplankton groups (green, diatoms, blue-green, and cryptophyte algae) in a small mesotrophic Vendyurskoe Lake (Karelia) in the p

An approach to determining the frequencies of vibrations of ribbed shells with axisymmetric imperfections under different types of loads is proposed. The effect of rib parameters, loads, and imperfections on the minimum frequencies of vibration of cy

An approximate approach to the estimation of critical load parameters of imperfect shells with a thickness decreasing for different reasons is proposed. Cylindrical shells, smooth, stiffened with stringers, with ring frames, and with stringers and ri

A numerical approach to the assessment of the critical stresses for imperfect ribbed shells is developed. Initial deflections occupying a part of the shell surface (they are circumferentially bounded) are considered. The couple stresses and nonlinear

This paper reports results from a hydrogeochemical study of thermal springs on Mutnovskii Volcano. The solutions of boiling pots and the pore water of thermal localities in the Donnoe Field were found to have an anomalous composition over a wide rang

The analytical method developed to determine the upper and lower critical stresses is applied to cylindrical shells reinforced with stringers and rings. Buckling modes typical of shells reinforced with discrete ribs are considered. The minimum critic

We present a procedure of analytical calculation of minimum natural frequencies of cylindrical shells stiffened with stringers and ribs. A new approach is put forward which allows for the presence of some axisymmetric imperfections in shells and a lo

Features of the composition of thermal sources in active volcanic regions reflect a multitude of factors influencing the spectrum and content of chemical elements in the solutions reaching the surface. The primary factor is the ratio of magmatic flui
