A method is provided for fabricating a PMOS transistor. The invention thus relates to the plants, seeds and tissue cultures of the variety CH552985, and to methods for producing a corn plant produced by crossing a corn plant of variety CH552985 with itself or with another corn plant, such as a plant of another variety. On the other hand, in response to a validation request including a digital-signed-digital document and a public key from a sign validating device 20, the server 30 compares a value resulting from the decryption of the digital sign with the public key and a digest value of the digital document canonicalized and returns the result to the sign validating device. If the web service customer is authenticated and authorized, a session and session ticket are created. The sensing pixels generate signals as a function of the light produced. The composite sacrificial material includes a polymeric or oligomeric matrix with filler material mixed therein.
