Sentence examples for decay of activity from inspiring English sources

"We will stay with the comet through its most active phase, and then afterwards through the decay of activity.

On the other hand, too much strong Brønsted acid leads to rapid decay of activity because of coking and cracking.

Several surface treatments have been studied in order to find suitable procedures for catalytic activity recovery, but regular decay of activity is always observed after every treatment.

The Pd@S1 not only exhibits excellent reactivity at low Pd adoption (Pd/PhI= 0.0025) during the reaction, but also can be reused for more than 10 runs with negligible loss of activity, in contrast to rapid decay of activity of conventional Pd/C catalysts.

Growth on Fe is characterized by a relatively high growth rate (∼50 μm/min) and long catalyst lifetime (>90 min), with the catalyst showing no decay of activity, while growth on a Co catalyst shows a lifetime of ∼60 min, with a slower growth rate of ∼7 μm/min.

However, at a very high temperature, denaturation of biological materials might occur, and in the case of 213Bi, a longer reaction time will result in decay of activity.

These findings are perhaps consistent with the view that this early LRP effect reflects the decay of motor activity and activity from reafferent processes (Leuthold and Jentzsch 2001 , 2002 Steinhauser et al. 2009).

where x i is the node's activity, μ i the natural decay rate of activity, τ i the time lag of feedback inhibition, τ e the delay of feedforward excitation and both F i ( x ) and G i ( x ) are bounded monotonically increasing functions that represent inhibitory and excitatory synaptic activation, respectively.

The occipital and posterior cingulate source showed a comparatively strong activity during the first laser stimulus, and a decay of source activity during subsequent stimuli, illustrated for stimuli 1, 5 and 10 in Figures 3A 3E.

The decay of catalyst activity in a diffusion-influence isothermal single catalyst pellet is characterized by idealized mathematical models.

Under such conditions both steady state and dynamic reactor performances were affected by the progressive decay of catalyst activity.
