Abstract:
The present invention provides an optically active compound of general formula (I) and salts thereof: wherein R' is selected from a group consisting of t-butyl amine, n-butylamine, iso- butylamine, iso-propyl amine, 4-phenyl-piperazine-1-ylamine, 4-(2-methoxyphenyl)- piperazin-1-ylamine, and 3, 4-dimethoxy phenethyl amine; wherein R 1 , R 2 and R 3 are selected from the group consisting of hydrogen, methyl or iso pentenyl; R 4 , R 5 and R 6 are selected from the group consisting of OH, O-alkyl, O-benzyl, O-substituted phenyl or combination thereof.
Abstract:
Embodiments of the present disclosure are directed to a ring protection device. The ring protection device can have a shell layer to at least partially encase a ring. The ring protection device can have a shell layer containing a housing segment. The segments of the shell layer can be connected to other segments via a hinge mechanism. The shell segments and hinge mechanism can be configured to encase a ring and protect it from damage. The shell layer can be connected to a sealing layer to aid the ring protection functionality. The hinge mechanism can be opened and closed to insert and remove a ring into the ring protection device.

Abstract:
The present invention provides a method, a system and a computer program product for maintaining data consistency between multiple databases. A dependency graph for a data entity is generated based on a declarative specification the data entity. A source instance and a destination instance of the dependency graph are instantiated. Each data record in the source instance and a corresponding data record in the destination instance are compared to ascertain data consistency therein. One or more database transactions are performed based on the result of such consistency analysis.
