The alternating acceleration caused by the power impulse and deceleration caused by compression result in nonuniform rotation.
A typical parabolic flight manoeuvre provides alternating acceleration levels of regular gravity (1 g), microgravity (0 g) for 22 s, and two periods (20 s) of hypergravity (up to 1.8 g for 20 s) before and after each period of microgravity.
Mössbauer data were recorded on a spectrometer with alternating constant acceleration.
Mössbauer spectra were recorded on a spectrometer with alternating constant acceleration.
Mössbauer spectra were recorded on alternating constant acceleration Mössbauer spectrometers equipped either with a Janis SVT-400 variable-temperature cryostat (weak-field) or a Janis 8TMOSS-OM-12SVT variable-temperature cryostat (strong-field).
The alternating signs are in principle consistent with the alternating CMB secular acceleration pulses described by Chulliat et al. (2015), but in particular, our surface observations around 2012 indicate an additional or more complicated source than just a pulse similar to their 2006 one.
When slowing alternates with rapid acceleration of the heart rate (tachycardia) in sick sinus syndrome or when bradycardia is accompanied by congestive heart failure or other serious complications, an artificial pacemaker may be necessary to regulate the heart rate.
The cap are sometimes zonate (marked with concentric lines that form alternating pale and darker zones); this depends on changes in the humidity of the environment, as variations in the amount of moisture will cause alternating periods of acceleration or slowing of growth.
Interestingly, pig neutrophils exhibited periods of very slow rolling (mean velocity < 10 μm/s) alternating with sudden acceleration, rapidly followed by deceleration (Fig. 7B).
In particular, pig neutrophils, and also bovine and equine neutrophils, exhibited periods of very slow rolling velocity, alternating with rapid accelerations and decelerations (Fig. 7).
