A distributed packet switch to control data packet flows in a network is described. The present invention further relates to the use of these alkoxylated polyalkyleneimines as a soil detachment promoting additive to laundry detergents and cleaning compositions and to laundry detergents and cleaning compositions which comprise these alkoxylated mono- or polyalkyleneimines. The messaging client is configured to send outgoing messages, each of the messages having message characteristics, to determine whether a record for an addressed recipient of an outgoing message exists in the data store, and to select messaging settings to control the message characteristics of the outgoing message based on the record where a record exists. Queries to the network, which may be written in any native search description language, are also translated to normalized schema prior to performing the search. A semiconductor material is formed between the source contact and the drain contact. The flange portion further has an inwardly-facing land at an outer edge of the engagement face which restrains the component against radial movement.
