Abstract: Plasticizer compositions are prepared by reacting a vegetal oil with isopentyl alcohol to provide a glyceride/fatty ester composition comprising from about from about 40 to about 80% wt isopentyl fatty acid ester, and reacting the glyceride/fatty ester composition with acetic anhydride to form an acetylated glyceride/fatty ester composition. The vegetal oil may be epoxidized before the reaction with isopentyl alcohol, or the acetylated glyceride/fatty ester composition first prepared and then epoxidized. Epoxidized acetylated glyceride/fatty ester plasticizer compositions are also described. Alternatively, plasticizer compositions are prepared by preparing a C4-C10 fatty ester composition separately from acetylated glyceride composition and mixing the compositions in a weight ratio of 3:7 to 7:3. The C4-C10 fatty ester composition and the acetylated glyceride composition may be epoxidized either before or after mixing.

Abstract: In a method for managing a directory (10) stored on at least one server (8), the directory (10) includes entries (12) arranged in a tree structure. Each entry (12) includes at least one attribute. An alias entry (12A) includes an attribute pointing to a target entry (12T). The method includes assigning to an application (14) an owner role in relation to an alias entry (12A). An application (14) is referred to as owner of the alias entry (12A). The method further includes requesting, by an application (14), deletion of the alias entry (12A), determining if a deletion condition is satisfied, and, if so, deleting the alias entry (12A). The deletion condition includes that the application (14) is the only owner of the alias entry (12A). A controller (30) for managing a directory (10), a server (8) including a directory (10), a system, and a computer program are also disclosed.

Abstract: Method and system to manage the state maintenance and the traffic maintenance of a Signalling Gateway Process (SGP), and of the corresponding Signalling Gateway (SG) or SGs served by such SGP, in scenarios where traditional Switched Circuit Network (SCN) signalling is transported over data networks, such as IP-networks. The method and the system for implementing the method involve defining a set of messages exchanged between a SGP and one or a set of concerned (connected) Application Server Process (ASP); driving the corresponding state-machines by the reception of such messages; and defining procedures for sending such messages and for receiving such messages. These messages can, optionally, convey also information about the destination routing parameters served by the SGP that become available or unavailable in the SCN through such SGP.
