Possible extreme fluctuations of sea level in the area of the Akkuyu nuclear power plant induced by tsunami, wind, waves, and tides are discussed. The probability characteristics of dangerous sea-level rise in the area are estimated using hydrodynamic modeling and historical data.

Considered are the issues of the impact of the Don River runoff on the water level in the eastern part of the Taganrog Bay as well as the issues of the determination of the real depth in this part of the sea. Investigated are the cases of the wind absence and wind of western and eastern directions. Presented is the forecast of the sea level in the eastern part of the Taganrog Bay.

Natural fluctuations of the Sea of Azov level are determined by means of hydrodynamic modeling based on the equations of long waves in a homogeneous incompressible liquid in the Coriolis force field. The results of computations demonstrated the presence of the series of level fluctuations against a background of the amphidromic system rotating anticlockwise around the central part of the sea.

Some results of theoretical studies of detonation processes in combustible gaseous mixtures are discussed for a model geometry of large combustion chambers of detonation engines in the case of mixtures of hydrogen and oxygen-enriched air. The effect of geometric characteristics on the operation of pulse detonation engines is analyzed. In particular, the propagation of detonation waves in tubes of small diameter to larger volumes and the evolution of detonation under the action of converging shock waves are considered.

Parallel with the traditional hypotheses on the predominantly wind (Ekman), gradient, and thermohaline nature of large-scale currents in seas and oceans, there exist hypotheses on the participation of long-period waves in the formation of these currents. As the physical mechanisms of generation of currents by waves, one can mention nonlinear wave transport and the phenomenon of negative viscosity in waves. From the viewpoint of existence of these mechanisms, numerous scientists explain high velocities of jet currents and their stable character. The predominant role of winds and thermohaline processes in the formation of large-scale currents is also accepted. On the basis of the experimental data, we demonstrate additional possibilities for the formation of large-scale currents given by the transport of water masses by long-period waves.

As you know, a direct inguinal hernia is called a hernia that protrudes the peritoneum in the region of the medial inguinal fossa and penetrates into the inguinal canal outside the spermatic cord through the inguinal gap. It is always acquired.

We would like to share the experience of the interdistrict children's surgery department, which was organized in February 1980 at Leninogorsk Children's Hospital. The department's profile is to provide scheduled and round-the-clock emergency surgical care for children (107631 people) living in six (Leninogorsk, Almetyevsk, Aznakaevsk, Bugulma, Bavly, Cheremshansk) districts attached to TASSR.
