On the other hand, the steric hindrance of the crown ether ring would shield the active center
, which is not advantageous to the formation of the active oxygen affinity species and the inclusion to the substrate.
The ACTIVE Center
(2) is designed to provide a dynamic physical and virtual environment that supports active, collaborative learning; skill mastery through in-class problem solving; and laptop-based in-class laboratory activities.
The Lancer Evolution VII, with an engine capacity of 2000 cc, features a newly developed Active Center
Differential (ACD), which ''brings better handling response and traction,'' it said.
After cross-cutting, the active center
winder is accelerated in order to achieve the necessary intermediate space for the winder change.
Green plants do it with the help of a cluster of 100 to 200 chlorophyll molecules, or "antennae pigments," to harvest light energy and transfer it to an active center
where the first steps of photo-synthesis occur.
Gallagher III, formerly of Kitt Peak National Observatory, now director of the Lowell Observatory in Flagstaff, Ariz., have found such evidence in the form of a pattern of velocities indicating a flow of matter out of the active center
of that galaxy.
