We present the confirmed validity of the prediction（made in unpublished article（simonenko, 2019 b） presented on December 9, 2019 to the journal Energy Research） of the thermohydrogravidynamic theory（simonenko, 2014） concerning the evaluated probabilities of the forthcoming intensification of the global seismotectonic, volcanic, climatic and magnetic processes of the Earth during the evaluated beginning（from December 7, 2019 to April 18, 2020） of the established in 2012 AD（simonenko, 2012 a） and finally confirmed in 2019 AD（simonenko, 2019 a） "first forthcoming subrange 2020 ÷ 2026 AD of the increased intensification of the Earth" determined by the combined non-stationary cosmic energy gravitational influences on the Earth of the planets（Mercury, venus, Mars and Jupiter） and the Sun（owing to the gravitational interaction of the Sun with Jupiter, Saturn, Uranus and Neptune）.

The Confirmed validity of the Explanatory Aspect of the Thermohydrogravidynamic Theory Concerning the Evaluated Maximal Magnitude of the Strongest Earthquake of the Earth near the Predicted Date 2021.1 AD during the Range from October 27, 2020 to May 17, 2

作者： sergey v.simonenko v.I.Il’ichev Pacific Oceanological Institute Far Eastern Branch of Russian Academy of Sciences

We present the confirmed validity of the significant explanatory aspect of the thermohydrogravidynamic theory（simonenko, 2007, 2009, 2012-2020） concerning the evaluated（on April 7, 2021, especially for the presentation on the 11 th International Conference on Geology and Geophysics） maximal magnitude 7.725 of the possible most strongest earthquake during the considered（simonenko, 2020） intensification of the global natural processes of the Earth from December 7, 2019 to April 18, 2020 AD. To obtain the satisfactory explanation of the maximal magnitude M = 7.7（according to the U.S. Geological Survey） of the strongest earthquake occurred on January 28, 2020 AD（123 km NNW of Lucea, Jamaica） near the calculated（simonenko, 2020） mean date（February 5, 2020 AD） of the probable most strongest earthquake during the considered（simonenko, 2020） range from December 7, 2019 to April 18, 2020 AD, we have analyzed the strongest earthquakes of the Earth occurred near the calculated local maximal combined（planetary and solar） integral energy gravitational influences on the internal rigid core of the Earth.

作者： sergey v.simonenko v.I.Il’ichev Pacific Oceanological Institute Far Eastern Branch of Russian Academy of Sciences

We present the explanation(in the frame of the established thermohydrogravidynamic technology) of the maximal magnitude M = 8.1(according to the U.S. Geological Survey) of the strongest earthquake of the Earth occurred in Kermadec Islands, New Zealand on March 4, 2021 AD(during the considered range from October 27, 2020 to May 17, 2021 AD). This strongest earthquake occurred near the calculated date 2021.1 AD corresponding(in the frame of the thermohydrogravidynamic theory) to the local maximal combined planetary and solar integral energy gravitational influence on the internal rigid core of the Earth. To obtain this explanation, we have analyzed the strongest earthquakes of the Earth(according to the U.S. Geological Survey) occurred near the dates of the local maximal combined planetary and solar integral energy gravitational influences on the internal rigid core of the Earth.

The practical significance of the established generalized differential formula-tion of the first law of thermodynamics (formulated for the rotational coor-dinate system) is evaluated (for the first time and for the mesoscale oceanic eddies) by deriving the general (viscous-compressible-thermal) and partial (incompressible, viscous-thermal) local conditions of the tidal maintenance of the quasi-stationary energy and dissipative turbulent structure of the mesoscale eddy located inside of the individual fluid region of the ther-mally heterogeneous viscous (compressible and incompressible, respective-ly) heat-conducting stratified fluid over the two-dimensional bottom topog-raphy characterized by the horizontal coordinate x along a horizon-tal axis X. Based on the derived partial (incompressible) local condition (of the tidal maintenance of the quasi-stationary energy and viscous-thermal dis-sipative turbulent structure of the mesoscale eddy) and using the calculated vertical distributions of the mean viscous dissipation rate per unit mass and the mean thermal dissipation rate per unit mass in four regions near the observed mesoscale (periodically topographically trapped by nearly two-dimensional bottom topography h(x) eddy located near the northern region of the Yamato Rise in the Japan Sea, the combined analysis of the energy structure of the eddy and the viscous-thermal dissipative structure of turbulence is presented. The convincing evidence is presented of the tidal mechanism of maintenance of the eddy energy and viscous-thermal dissipa-tive structure of turbulence (produced by the breaking internal gravity waves generated by the eddy) in three regions near the Yamato Rise subjected to the observed mesoscale eddy near the northern region of the Yamato Rise of the Japan Sea.

Testing rocket and space technology objects in ground conditions for resistance to the impact of meteoroids and fragments of space debris can be carried out using shaped charges. To substantiate the design parameters of shaped charges that ensure the formation of aluminum particles in a wide velocity range(from 2.5 to 16 km/s), numerical modeling of the formation process was carried out within the framework of a two-dimensional axisymmetric problem of continuum mechanics using three different computing codes to increase the reliability of the results. The calculations consider shaped charges with a diameter of 20-100 mm with aluminum liners of various shapes. It is shown that the formation of particles with velocities close to the lower limit of the considered range is ensured by gently sloping segmental liners of degressive thickness. To form higher-velocity particles with velocities over 5 km/s, it is proposed to use combined liners, the jet-forming part of which has the shape of a hemisphere of constant thickness or the shape of a semi-ellipsoid or semi-superellipsoid of rotation of degressive thickness.
