A method and system for estimating reservoir pressure in a hydrocarbon reservoir from downhole pressure measurements of producing wells is disclosed. The hollow drive tube partially contains the heat transfer medium and is connected to and opens into the acoustic resonator. A polymer coating is extruded over both the substrate surface and the strip. The invention further provides for methods of preparing the combinations of the invention. Certain exemplary embodiments of the present invention can also be used to determine certain contributions of individual electronic energy levels within the materials to the total 15 absorption. Where values are determined for a plurality of activity metrics, the list may be ordered according to the one of the activity metrics selected by the user.
