This booklet offers the correct results of lately came across and interdisciplinary phenomena, brought on by way of neighborhood mechanical instabilities. particularly, it appears at emissions from nano-scale mechanical instabilities akin to fracture, turbulence, buckling and cavitation, focussing on vibrations on the TeraHertz frequency and Piezonuclear reactions. destiny purposes for this paintings may possibly comprise earthquake precursors, weather swap, strength construction and mobile biology.
A sequence of fracture experiments on ordinary rocks demonstrates that the TeraHertz vibrations may be able to result in fission reactions on medium weight parts observed via neutron emissions. an identical phenomenon appears to be like to have happened in different various occasions, relatively within the chemical evolution of the Earth and sun process, via seismicity (rocky planets) and storms (gaseous planets). because the authors discover, those phenomena may also clarify puzzles on the topic of the historical past of our planet, just like the ocean formation or the primordial carbon toxins, in addition to medical mysteries, just like the so-called “cold nuclear fusion” or the proper radio-carbon relationship of natural fabrics, similar to the Turin Shroud. In biology, Piezonuclear reactions might clarify the mechanism that governs the so-called "sodium-potassium pump" and extra in most cases, the metabolic processes.
Scientists engaged in seismology, geophysics, geochemistry, climatology, planetology, condensed topic physics and b
iology, in addition to these considering theoretical and utilized mechanics, will all delight in the leading edge paintings offered right here in a holistic way.

The maps, with dimensions of about 250 μm Â 200 μm, were analyzed before the loading tests. The typical concentration on external surfaces show high percentages of Fe (~65 %) (b) and O (~30 %) (c).

As a matter of fact, the greater the size-scale and the slenderness, the higher the neutron bursts. In the present paper, Luserna stone (a granitic rock), Basalt, and Magnetite, containing different iron concentrations, were tested in fatigue experiments using low (2 Hz), intermediate (200 Hz), or high (20 kHz) frequency. We investigated different cyclic conditions to confirm that energy emission in the form of neutrons takes place also in the case of fatigue tests under different frequency regimes.
