Abstract: A method in support of potential future delivery of digital content items over a data network includes obtaining at a server over the data network at least one digital content item for potential future delivery and delivery metadata pertaining to potential future delivery of the digital content item. The delivery metadata includes at least one recipient and a monitoring interval. The digital content item is stored by a processor of the server, and, during the monitoring interval, a user account associated with the digital content item is monitored by the processor for an occurrence of an inactivity benchmark. Upon a lapse of the monitoring interval without an occurrence of the inactivity benchmark, the digital content item is delivered to the at least one recipient. A system can be constructed to implement the method described herein.

Abstract: A method for producing menatetrenone that does not have a deleterious influence on the environment, that is safe even when applied to large-scale production, and that is also simple to operate, wherein a compound represented by the following formula (1) is produced by treating with an oxygen source, and without the addition of an additive other than water or aqueous sodium chloride solution, a reaction solution consisting essentially of a solution of a compound represented by the following formula (2) dissolved in a solvent:
