This e-book provides the proper results of lately stumbled on and interdisciplinary phenomena, caused by way of neighborhood mechanical instabilities. specifically, it seems to be 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 functions for this paintings might 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 followed through neutron emissions. an identical phenomenon seems to be to have happened in different assorted events, fairly within the chemical evolution of the Earth and sunlight process, via seismicity (rocky planets) and storms (gaseous planets). because the authors discover, those phenomena may also clarify puzzles with regards to the background of our planet, just like the ocean formation or the primordial carbon pollutants, in addition to clinical mysteries, just like the so-called “cold nuclear fusion” or the proper radio-carbon relationship of natural fabrics, corresponding to the Turin Shroud. In biology, Piezonuclear reactions may possibly clarify the mechanism that governs the so-called "sodium-potassium pump" and extra as a rule, the metabolic processes.

Scientists engaged in seismology, geophysics, geochemistry, climatology, planetology, condensed topic physics and b

iology, in addition to these focused on theoretical and utilized mechanics, will all delight in the cutting edge paintings offered the following in a holistic way.

The fracture surfaces of specimen P2 were analyzed in order to recognize possible evidence of piezonuclear reactions. Taking into account the homogeneity of the chemical composition of this material (Fe-oxides content ~95 %), the analysis on the external surface of this rock was conducted in a different manner with respect to granitic orthogneiss and basalt.

Introduction It is possible to demonstrate experimentally that brittle fracture in solid materials can be accompanied by the release of different forms of energy [1–3]. In recent studies, it has been observed that quasi-brittle materials such as granitic orthogneiss (Luserna stone) subjected to compression tests under monotonic displacement control, by cyclic loading, or by ultrasonic vibration, are characterized by neutron emissions up to one order of magnitude greater than the background level [1–11].

This equipment allows to apply fatigue loading with a frequency range between 100 and 260 Hz, a mean load up to 50 kN, and an alternate load up to 50 kN. , the cyclic tests, using 2 Hz or 20 KHz as working frequency, were obtained by a servo-hydraulic press for low frequency and by a Bandelin HD 2200 sonotrode for ultrasounds [4, 5]. At a first glance, from the experiments reported in the literature, it was possible to correlate neutron emissions and consequent nuclear transmutations (compositional changes) [3–8].
