The present invention concerns a mixture of inorganic nitrate salts, comprising LiNO3, NaNO3, KNO3 and CsNO3 wherein the LiNO3 content ranges from 17. A body region is positioned so that a voltage bias on the gate electrode will cause an inversion layer in the body region. Deleting a cookie results in a cleaner request, but damaging a cookie may be more efficient in certain circumstances. The system and method is adaptive, in that the samples that are processed can shift as the information bearing point shifts relative to the sample points.
