A process for making tricyclodecenyl esters is disclosed. The apparatus may also include a storage unit for storing the initial breath samples and the subsequent breath inputs. A mobile terminal receiving a differential BSPM updates the flows with the information contained within the differential BSPM or adds the information contained within the differential BSPM for a new flow. Preferably the boron compound is capable of reducing the adsorbed portion of the metal source compound into its elemental electrical state. A pivot lever is rotatably installed inside the shutter housing and engaged with the shutter panel such that the shutter panel is pivoted to open and close the through-hole. As data elements in the group are traversed, the reader traverses the links between new and old data element versions to find a version having a matching generation number, if any.
