A hot melt adhesive comprising an adhesive polymer and a modified rosin-terpene, preferably a phenol modified rosin terpene. A method includes receiving a set of data relating to Quality of Service pre-authorization, and conditionally processing subsequent QoS configuration requests based at least in part on the pre-authorization information. Any sequences that are required to be present in cis on the rolling circle DNA replicon in order that the Rep protein might promote replication of the rolling circle DNA replicon and elicit an immunization reaction are included. In one embodiment, the communication network includes a number of information gathering devices such as traffic cameras that collect information on traffic conditions within the communication network. Electronic circuitry is also provided, that may be added to at least one of the hazard alarms, for transmitting and receiving digital information with other hazard alarms connected thereto.
