Abstract: Systems and methods are provided to track viral marketing. The resulting user interfaces can include a map that tracks propagation via a node tree or a geographic map that shows where media was viewed. The information may also be displayed as a cumulative or absolute tracking graph, which is based on various parameters, such as number of views, number of transmissions, rewards earned, etc. The systems and methods can track viral propagation through, e.g., email, social networking service or site messages or postings, and instant messages. Data used by the invention include URLs as received from a media transmission page form, the URLs pertaining to both the propagator and the recipient, time stamps at which the media was propagated and viewed, and so on.

Abstract: An ergonomically profiled hand grip for a hand-held tool. The hand grip has a contoured top surface and a pommel attached thereto. The centerline of the pommel is offset from the axis of the contoured top surface at an angle of approximately 45.degree.. The pommel is contoured to comfortably fit between the thumb and index finger of the user while the fingers extend over the top surface. Preferably, the pommel is rotatably attached to the top surface making the hand grip equally accessible and comfortable to right and left hand users and for users with large or small hands.

Abstract: In the thermal cracking of a hydrocarbon feedstock, the quenching of the gases leaving the cracking zone is deliberately deferred for a very short time to permit continued endothermic reaction and thereby increase the ethylene yield.
