Administration of BAA increased calpastatin activity at 20 d (1.1 vs 1.5 units/g), but not at 0 h (3.9 vs 4.8 units/g) postmortem, decreased myofibril fragmentation index (60.7 vs 44.9), and increased shear force (8.2 vs 10.9 kg) at 20 d postmortem (P < .05). These data suggest ...
Cellular signaling networks are complex and appear to include many nonfunctional elements. Recently, it was suggested that nonfunctional interactions of proteins cause signaling noise, which, perhaps, shapes the signal transduction mechanism. However, th
A force is a vector quantity which means it has both magnitude and direction. When objects interact with one another, it is likely to cause a push or pull resulting in the Force. For example, when you try to push a ball, it causes a force on the ball that changes its state of ...
Get inspired with a wide selection of built-in effects or customize your own. Make it storm. Add lasers. Or even pop a spinning UFO into a tracking shot. Turn any idea into an effect your audience will never forget. Explore After Effects features. ...
The effect of shear force on aerobic granulation was studied in four column-type, sequential aerobic sludge blanket reactors. Hydrodynamic turbulence cause
Between the end of the previous and the start of the next stimulation trains was a minimum interval of 5000 ms. Full size image Figure 2 Transcranial alternating current stimulation. (A) Bifocal electrode montage with centre electrodes (surface area 9 cm2, diameter 3.4 cm) over C3 ...
if we did not tell participants that the study could contain pornographic materials it would be unethical to force participants to view material that some find objectionable (and may even cause participants harm). Third, our method allows participants to indicate no use of pornography and not cause...
Sexual selection is an important evolutionary force that can drive rapid phenotypic diversification within and among species1,2,3,4,5and even promote speciation6,7. For example, competition for mates drives the evolution of traits that can increase attractiveness to the opposite sex and/or increase...
Our results can explain why early claiming has remained very high in the last years even as the early retirement penalties have increased substantially compared with previous periods, and why labor force participation has remained quite high for older workers even in the midst of the worse ...
