Solid-Liquid Phase Transition As a Mechanism of Volcano Eruption

This paper considers the formation of the magma volcano chamber and its eruption due to melting of the matter within the earth crust because of heating caused by plastic deformation occurring during tectonic movement. The expansion of matter in the magma chamber which takes place during its heating, leads to elastic stresses in the solid shell surrounding the magma chamber. The elastic energy of such stresses can be as high as 10^17 J per 1 km3 of the melt. The magma flow rate has been assessed according to available data, which agrees well with the observation data. The mechanism of low-frequency vibrations produced by the magma chamber is discussed. The vibrations result from the excess elastic energy formed during melting at the eruption steady stage. The suggested radiation theory allows evaluating the size of the magma chamber according to parameters that can be measured. The obtained theoretical evaluation of the magma chamber size is supported by the available observation data.

Nonpotential Solution of the Electron Problem

Modern physics makes wide use of the equation for which only a potential solution is sought. The probability that this equation has a nonpotential solution is omitted from consideration automatically without any explanation. In this paper, using the electron problem as an example, an exact nonpotential solution linearly independent of the classical one is found. A solution with minimum potential energy is chosen as a physically feasible solution. The force acting on an electron with a nonpotential field in a homogeneous electric field and the interaction energy of two electrons with a nonpotential field is determined. The interaction energy depends on three angles responsible for mutual orientation of the electrons. Taking into account a nonpotential solution explains why there exist two types of neutrons: a neutron and an antineutron, why annihilation of the antineutron - proton is possible whereas that of the proton - neutron is impossible, why neutrons behave similar to protons. All the above properties result from the nonpotential character of an electric field.

Potential. Solution of Poisson's Equation, Equations of Continuity and Elasticity

The modern theory of the potential does not give a solution of Poisson's equation. In the present work its solution has been found via generalized functions and a nonpotential solution of the continuity equation has been obtained. The method is demonstrated by the solution of elasticity equations using the example of a crack in the infinite specimen and a surface crack. Their elastic energies have been calculated. In has been shown that there is no critical condition for a crack in the infinite specimen and the crack always closes. Only the surface crack possesses the critical condition.

Tornado lift

It is shown that one of the causes for tornado is Tornado Lift. At increasing vortex diameter its kinetic energy decreases to keep the moment of momentum constant. A kinetic energy gradient of such vortex is Tornado Lift. Evaluation shows that contribution of Tornado Lift in air lifting in a tornado is comparable to buoyancy according to the order of magnitude.

Crystal Electrostatic Energy

It has been shown that to calculate the parameters of the electrostatic field of the ion crystal lattice it sufficient to take into account ions located at a distance of 1-2 lattice spacings. More distant ions make insignificant contribution. As a result, the electrostatic energy of the ion lattice in the alkaline halide crystal produced by both positive and negative ions is in good agreement with experiment when the melting temperature and the shear modulus are calculated. For fcc and bcc metals the ion lattice electrostatic energy is not sufficient to obtain the observed values of these parameters. It is possible to resolve the contradiction if one assumes that the electron density is strongly localized and has a crystal structure described by the lattice delta - function. As a result, positive charges alternate with negative ones as in the alkaline halide crystal. Such delta-like localization of the electron density is known as a model of nearly free electrons.
