The method involves using a fluorescent dye on the biological tissue, where the fluorescent dye is selected from patent blue v, isosulfan blue, toluidine blue, hypericin, indocyanine green, mvac, or doxorubicin, and using a microscopic linear or non-linear imaging system to form an image of the biological tissue, where the fluorescence of the dye reveals the morphology of the tissue at cellular scale..

Method of pre-treating a filter used in a small-scale water separometer


The safety and proper performance of jet aircraft engines requires that any contamination of jet fuel, for example by water or by improper contaminants, be filtered (removed) before delivery of the fuel, through hoses, to the fuel tanks of the aircraft. Coalescing devices and filters in the fuel delivery system are used to attain this result.
