The exemplary embodiments of the invention, as further described herein, provide apparatus, methods and computer program products that, for example, address the notification issue that can occur in extensible markup language document management when a new entry is added to a Shared List document that is referred to from a Shared Group document. A device is provided to sense when the room is occupied, such as by detecting the light level in the room. The invention provides for a chemical reaction between a coupling agent and silica which is substantially decoupled from a reaction between a coupling agent and starchplasticizer to form a filler reinforcement network in situ within the elastomer host followed by a subsequent phase mixing of the carbon black therewith. Objects in the data structure are retrieved and the application is informed of assigned handles thereby enabling the application to access retrieved objects. The design of the connector and the selection of materials facilitate easy installation and help avoid cyclic fatigue and cracks that could result in a loss of hermetic seal.
