Zhang et al. (2011) built a single-phase fluid flow pattern in fractured-vuggy media with different vug densities, and concluded that with an increase in vug density, the pressure gradient at the same velocity declined and the critical velocity increased.
Head movement was marked from the onset of gaze till the time point at which head velocity declined below 15°/s.
For movement analysis, the onset of gaze (movement of eye in space) was selected at the time when gaze velocity exceeded 50°/s and gaze offset was marked as time point when velocity declined below 30°/s.
In 1933 in Econometrica, published by the Econometric Society, which he co-founded, he described debt deflation as a sequence of distress-selling, falling asset prices, rising real interest rates, more distress-selling, falling velocity, declining net worth, rising bankruptcies, bank runs, curtailment of credit, dumping of assets by banks, growing distrust and hoarding.
In the unloaded zone, velocity declines dramatically at 12,400 ft TVDml with very little or no change in bulk density (Fig. 2) validating the fact that density can increase even in the zone of unloading.
When the vacuum chamber with 5/34 of the tunnel volume was connected to the flank of the tunnel, gas explosion of the same concentration would greatly weaken with flame propagation velocity declining to about 200 m/s, the quenching distance decreasing to 3/4 of the tunnel length, maximum peak value overpressure running down to 0.1 0.15 MPa and specific impulse of shock wave below 0.9 kPa s.
The grip strength declines in the latter study correlated strongly with nerve conduction velocity declines (r = -0.70), and moderately with increased nerve and muscle cytokine production (r = -0.38 and r = -0.41, respectively) [ 19].
These changes are more noticeable in the aged participants (61 80 years) and could be related to the loss of efficiency of physiological processes in old age (ie, nerve conduction velocity declines with increasing age, action-potential amplitude is reduced, etc).
Furthermore, nerve conduction velocity declines with increasing age (Rivner et al 2001; Valerio et al 2004) and action-potential amplitude is reduced (Bouche et al 1993; Caruso et al 1993).
During pauses, mitochondrial instantaneous velocities declined to 0.5 µm/sec over 1 second.
In this study by Diller and colleagues, left ventricular ejection velocities declined to preoperative values by 18 months, with persistent right ventricular dysfunction.
