derived from the Greek wordskata("down") andlyein("loosen.") As Berzelius defined it, catalysis involved an activity quite different from that of an ordinary chemical reaction. Catalysis induced decomposition in substances, resulting
the dataset was comprised of 64 examples for the L-M arousal class and 40 examples for the M-H arousal class. Regarding valence, we distinguished the L-M from the M-H valence regardless of the images belonging to the neutral classes. This choice is justified by the fact that the neutral...
Two-phase reaction for stage 2 region during discharge process. One-dimensional profile of the diffraction patterns for carbon during the discharge process at the 0.05 C rate. The diffraction peaks of the 004 and 006 reflections are indicated in the figure. The peak splitting of the 004 reflecti...
摘要: In this paper, we consider two methods of computation of failure probabilities by adapted polynomial chaos expansions. The performance of the two methods is demonstrated by a predator–prey model and a chemical reaction problem.会议名称: Conference on the Mathematics of Finite Elements & ...
Overall, full N2O decomposition could be reached at temperatures as low as 490掳C in realistic reaction conditions. Additionally, stability tests emphasise stable activity for at least 60h. Furthermore, no irreversible deactivation even in the presence of NO, O2 and H2O was found. The catalysts ...
1.1 Illustrative examples These challenges can present themselves in a wide array of task scenarios. We choose three examples, from robotics, healthcare and software systems to illustrate how these challenges can manifest themselves in various ways. A common robotic challenge is autonomous manipulation,...
Proof. Let f(x) = Σjαjaj(x) be an atomic decomposition of f. By Lemma 6.10, the sequence {Σ1NαjH(aj)}∞N=1 is Cauchy in L1 and (6.30)‖Hf‖L1≤c0∑j|αj|.But (6.24) shows that atoms lie in the unit ball of L1. Hence, (6.31)‖f‖L1≤∑j|αj|.Now taking th...
15N- and13C-glutamine were detected in both the underground and aboveground parts of the plant by a high-performance liquid chromatography equipped with an ion trap mass spectrometer. The results suggested that glutamine itself was absorbed from the root without decomposition in the rhizosphere and ...
lifetime are small. Here, we rely on the results of time-independent quantum-mechanical studies of reactive atom-dimer collisions with alkali-metal atoms and molecules72,73. They found that total reaction rate coefficients are not affected when the non-additive part of the potential is or is ...
Myoelectric hand prostheses offer a way for upper-limb amputees to recover gesture and prehensile abilities to ease rehabilitation and daily life activities. However, studies with prosthesis users found that a lack of intuitiveness and ease-of-use in the human-machine control interface are among the...
