The potential of the proposed model-based simulation procedure is demonstrated through 1D and 2D isothermal cases including cased bomb expansion and fragmentation, blast wave expansion through a broken case, and blast and fragment impact on a concrete wall.
Controlled, forced collapse of cavitation bubbles for improved stone fragmentation during shock wave lithotripsy.
The feasibility of using controlled, forced collapse of cavitation bubbles for improved stone fragmentation during shock wave lithotripsy was demonstrated using microsecond tandem shockwave pulses.
According to these studies, one can conclude that a conventional blasting process has two major stages which contribute to crack propagation and rock fragmentation: (a) stress wave and (b) gas pressure.
We show in experimentally relevant regimes and device configurations, that transmission resonances, tunnelling probabilities, diffraction patterns and wave packet fragmentation of indirect excitons are largely determined by the internal dynamics, and could not be reproduced by point-like dipole models or mean-field calculations.
The relationship between gallstone fragmentation during extracorporeal shock wave lithotripsy (ESWL) and gallstone volume is poorly understood.
To better understand the mechanism of stone fragmentation during extracorporeal shock wave lithotripsy (ESWL), the model developed in Part I [P. Zhong and C.J. Chuong, J. Acoust. Soc. Am. 94, 19-28 (1993)] is applied to study cavitation microjet impingement and its resultant shock wave propagation in renal calculi.
Box has made an acquisition in the past — Increo Solutions, the document feedback and collaboration tool, back in 2009, but Levie says the bigger potential for Box is to ride the wave of fragmentation in the market (the very thing that is driving M&A) by becoming a platform for the rest to coexist peacefully together.
The wave of fragmentation of manufacturing activity benefited from the incorporation of large swaths of lower-wage workers from Asia and Eastern Europe into the global market economy (Canuto, 2015a).
Slow-wave sleep fragmentation also did not influence baseline perfusion within the caudate region of interest [ t(10) = 0.42, P = 0.68].
