on the scale of the equipment. This makes it increasingly necessary, due to the increased development of more active and selective catalysts, to quantitatively understand the change of the flow pattern with reactor scale and the interaction of it with mesoscale transport. Hence, moving the level ...

melanin went through a substantial change, possibly related to loss of functional groups, or may also be derived from the C–N stretching from the indole ring33. Regardless of these features, both bands can be confidently assigned to the stretching and plane vibrations of C–C, C–OH, C–N...

The effect of different types of case-sensitive matching, use of NP chunking, and removal of dictionary terms that were likely to be highly ambiguous or non-chemical, did not essentially change the performance. Our initial assumption about the beneficial effect of NP chunking on compound ...
Experiments change on weekly basis: these changes are often profound enough that adapting the veto/trigger parameters and algorithms to each experiment would represent a huge effort. At the 120 Hz repetition rate of the source, and the average size and quantity of sensors, our current system can...

values due to action by the brown-rot fungusS. lacrymansand the white-rot fungusT. versicolor. The mannose and glucose percent content in thermally–fungally attacked spruce wood was intensive reduced, e.g., by 17% to 98% in wood after thermal treatments at temperature equal and above 200...
(an exothermic process with ΔE< 0), the decrease in potential energy is accompanied by an increase in the kinetic energy (embodied in the momentum of the bonding electrons), but the magnitude of the latter change is only half as much, so the change in potential energy always dominates. ...
