Abstract: Systems and methods are taught for providing customers of a cloud computing service to control when updates affect the services provided to the customers. Because multiple customers share the cloud's infrastructure, each customer may have conflicting preferences for when an update and associated downtime occurs. Preventing and resolving conflicts between the preferences of multiple customers while providing them with input for scheduling a planned update may reduce the inconvenience posed by updates. Additionally, the schedule for the update may be transmitted to customers so that they can prepare for the downtime of services associated with the update.

Abstract: A method for improving the efficacy of polar additives used in polyolefins is disclosed. The method is related to the addition of an effective amount of a co-additive compound of the formula R1(OCH2CH2)xOH to the polyolefin prior to forming the film, wherein R1 is a straight or branched chain alkyl of 20 to 100 carbon atoms and x is 2 to 100. The presence of these materials in polyolefin resins allows less polar additives to be used without losing their efficacy and also leads to improved optical properties for films made from such resins.
