in particular, the aspect of non-integral powers of base units, which some might find unusual for units in the SI system. In many ways the fact that the units of the rate constants as usually defined convey information about the order of the reaction or reactions involved is very useful...

Catalysis is the phenomenon in which a relatively small amount of a foreign material, called a "catalyst," augments the rate of a chemical reaction without itself being consumed. The catalyst enters into reaction but is regenerated at the end of each reaction cycle. Thus, one unit of catalyst...
Results Post hoc analysis from the previous cohort yielded PRU of at least 220 as the optimal threshold for modified preparation selection. The thromboembolic event rate of the clopidogrel responders (one of 126 [0.8%]) was lower than that of the historical control group that received standard ...
relatively fast process and that the observed multiple oligomeric species corresponds to the equilibrium state of Bax in the membrane. In addition, the density of Bax particles detected on the SLBs increased with time, suggesting that membrane binding is the rate-limiting step in Bax oligomerization...
aLet's "test" Jed when I see him in a couple of weeks - please send me the English phonetic spelling of the Chinese word panda bear and I'll let you know what his reaction is. I do suspect that if he were to see a picture of you he'd remember you. 我们“测试” Jed,当我看见...
摘要: Recent advances in FCC short contact time operations coupled with heavier feedstocks have resulted in more catalytic crackers operating in a mass transfer limited regime. The rate of mass transfer-not catalytic activity-determines the reaction rate in these units....
A computer analysis of fluorescence induction curves of leaves treated with 3-(3,4-dichlorophenyl)-1,1 dimethylurea was done for several species. These measurements gave the ratios of the total chlorophyll to photosystem II reaction cent... S Malkin,DC Fork - 《Plant Physiology》 被引量: 192...
