A method for processing thermographic data is disclosed including thermally disturbing a sample collecting, as a function of time, thermal data from said sample, converting the collected data using a 2nd derivative function, and transforming the converted data using at least one Boolean operation. The pigment blend is then used, for example, to pigment a medical prosthesis, so that it matches precisely its wearer’s skin. In addition, a fan shroud is provided, in which plural ram pressure holes are formed in a portion which covers the FC radiator. A second trench is created through the second surface of the substrate effective to form, in combination with the first trench, a slot. This invention is further directed to the uses of the above compositions in the preparation of pharmaceutical compositions.
