Ultrasonic testing of austenitic stainless steel welds is often difficult because the ultrasonic beam is subjected to many perturbations : deviation, partition, distortions and sometimes ghost echoes. These perturbations are due to the anisotropic and heterogeneous metallurgical structure of the welds. We are carrying out a research program in order to(More)
RNA transcription processes were visualized within chromatin from cultured Mouse cells, spread according to Miller, and Bakken (3), by high resolution autoradiography. The cells were labelled for a short time with 3H-uridine and lysed using the detergent Nonidet P 40. Transcription complexes of both ribosomal ("Christmas tree"-like forms) and non-ribosomal(More)
