There are provided high power laser systems, apparatus and methods for performing laser operations in particular in environments where an optically obstructive medium may be present in the laser beam path, such as within the borehole of an oil, gas or geothermal well, or below the surface of a body of water. The predominant film-forming component is a negatively-charged latex polymer that has negatively-charged ionic groups other than carboxy groups. Vectors and host cells comprising the nucleic acid molecules encoding the FAO proteins, analogs, derivatives and enzymatically active fragments thereof are also provided. 29 and a dielectric constant of about 5. In one embodiment the peripheral circuits are formed in a silicon substrate and an N level array is fabricated above the substrate.
