Abstract: A method of decreasing a cycle time of a brazing process is provided. The method includes arranging each of first and second pairs of braze parts together, each of the first and second pairs of the braze parts having braze material interposed between the braze parts, stacking the first and second pairs of the braze parts to form a stack, interposing pyrolytic graphite (PG) between the first pair of the braze parts and the second pair of the braze parts in the stack and heating the first and second pairs of the braze parts to a brazing temperature to braze the braze parts of each of the first and second pairs of the braze parts together.

Abstract: Disclosed herein are compounds of Formula (I), or a pharmaceutically acceptable salt, ester, amide, thereof; and methods of modulating the activity of a cannabinoid CB2 receptor comprising contacting a compound of Formula I with the cannabinoid CB2 receptor. Also disclosed are methods of imaging of a tissue by positron emission tomography, the method comprising administering to the subject a compound of Formula I, wherein the compound comprises a radioisotope. Also disclosed are methods of measuring the relative concentration of cannabinoid CB2 receptors in tissue of a subject, by using a compound of Formula I which comprises a radioisotope. In addition, method of diagnosing a disorder in a subject are disclosed.
