We have studied numerically the evolution and decay of axion strings. These global defects decay mainly by axion emission and thus contribute to the cosmological axion energy density. The relative importance of this source relative to misalignment production of axions depends on the spectrum. Radiat

When the amount of the axion emitted from the axionic string and the a~ionic domain wall is evaluated, the number density of the source string should be necessarily determined. Although it is the simplest assumption that the axionic string obeys the scaling distribution similar to the cosmic gauged
The low energy coupling of the electromagnetic field to the axion leads to two distinct dispersion relations for the electromagneticaxion oscillations. The one frequency being the normal electromagnetic (E. M.) oscillation while the other represents a coupled oscillation. When a non-zero chemical po
## Abstract We consider the generation of acoustic waves by turbulent convection and perform spectral analysis of a monopole source of sound related to the heat production by condensation of moisture. A quantitative explanation of the correlation between intensity of infrasound generated by superce
