Reconstruction of the anterior floor of the mouth using a peroneal perforator free flap. A case report.

Personal experience is presented concerning a case in which reconstruction of the anterior floor of the mouth was carried out using a fascio-cutaneous free flap harvested from the lateral part of the leg; the flap pedicle is represented by perforating vessels originating from the peroneal vascular axis.

Ultrasonic testing of anaerobic bonded joints.

The paper deals with ultrasonic testing of adhesive joints between sheets of thickness greater than 1 mm, bonded by a "zero thickness" layer of anaerobic adhesive. In the case of equally thick sheets, interference phenomena can arise that make impossible the use of the "decay method" (a method previously developed by the authors for the case of non-zero adhesive thickness). Consequently an alternative method, termed "first peak", has been proposed. In order to evaluate the applicability of the two methods, a series of tests has been carried out on specimens having geometry suitable for both types of inspection. Also two different levels of surface roughness have been considered. The results allow for evaluating the defect detection capability of each method, accounting for the roughness effect, and give information on the suitable control procedures.
