摘要:
The present invention relates to a method for resolution of a mixture of pinocembrin optical isomers, in particular a pinocembrin racemate, using a chiral primary amine or a chiral sulfinamide. The present invention also relates to a (R)-(+)-pinocembrin obtained by the method.

摘要:
A system and method of selecting content within a web page (110, 300) may include, with a processor (125), determining spatial coordinates of a plurality of nodes (210 through 285) within the web page (110, 300), recording coordinates of a drawn portion (610) of the web page (110, 300), and determining, with the processor (125), a number of corresponding regions (710, 910) for the drawn portion (610) of the web page (110, 300) based on the spatial coordinates of the nodes (210 through 285).
